1. MEMORIA

Inverduino

1. Memoria descriptiva • Objeto

El objetivo de nuestro proyecto es el de construir invernadero o semillero

automatizado mediante hardware libre como lo es Arduino. En este caso he usado Arduino Mega por su mayor número de pines de entrada/salida.

• Antecedentes Existen muchos tipos de automatizaciones de invernaderos la mayoría compuestos por autómatas, mediante pic, incluso usando equipos informáticos usando sus puertos serie y paralelo. Estos sistemas mencionados suelen ser bastantes caros de implementar además de ser más complejo para un uso personal. Por lo que nuestro sistema es más favorable que los anteriores para un uso domestico.

• Datos de partida La primera idea que tengo es la de que necesito controlar y los actuadores que usare para ello. Necesitamos averiguar la temperatura/humedad del ambiente, la humedad de la tierra, la iluminación del ambiente y la capacidad del depósito que usaremos para el riego. Con estos datos activaremos una serie de relés que alimentaran a unos actuadores para cambiar esos valores a los que buscamos, esos actuadores son: ventiladores, célula Peltier, tira led, bomba de agua. Toda esta información será procesada por nuestra placa de Arduino y se verá reflejada en una pantalla Lcd de 20X4.

Inverduino

• Análisis y Descripción del circuito La alimentación de todo nuestro sistema lo realizamos mediante una fuente de alimentación de pc reciclada de un equipo antiguo. Para esto debemos de puentearla, uniendo el pin de Power On (color verde) con una Masa (cable negro).

Mediante esta fuente alimentamos con 12V DC nuestro Arduino Mega mediante un conector DC macho de 2.1mm. A nuestra placa arduino ya le hemos cargado anteriormente nuestro código de programación que posteriormente veremos.

Con la fuente también alimentamos la placa de 8 relés protegida mediante optoacopladores a 5V,alimentados por Arduino.

Inverduino

Los sensores usados son los siguientes:

• Sensor Humedad/temperatura DHT22:

• Sensor humedad tierra:

• Sensor fotoeléctrico o LDR:

• Sensor ultrasonidos HC-SR04

Inverduino

Nuestra placa arduino recoge la información proveniente de estos sensores y la transforma en datos que nosotros entendemos y mediante el código posterior procederá a usar según necesite a los siguiente actuadores:

• Bomba de agua sumergible:

• Ventiladores:

• Tira led smd 5050 12v :

Inverduino

• Célula Peltier 12v:

Toda la información de los sensores y si están en funcionamiento los actuadores podrá ser representado en la Lcd 20x4 con un adaptador con comunicación I2C que usare:

• Manual para el Cliente

Inverduino El “Inverduino es un sistema compuesto por 3 partes: La unidad de control, el invernadero de metra quilato y el depósito de agua, como vemos en la siguiente imagen:

Inverduino

Estas partes vienen separadas en el kit, para su ensamblaje en el lugar deseado. Para su ensamblaje solo necesitaremos un destornillador plano, como vemos en la imagen, para unir los cables con las clemas, estas vienen identificadas para mejorar su facilidad.

Inverduino

• Arranque: Despues del correcto ensamblaje de las 3 piezas procedemos a proporcionarle electricidad para hacerlo funcionar. Esto lo conseguimos mediante un cable de corriente similar a los usados en pc, incluido en el kit. Está compuesto por un conector Sucko 250v 16A y en el otro extremo, un conector IEC 60320 C13.Posteriormente debemos de asegurarnos que el interruptor de la fuente de alimentación está en posición de encendido.

• Configuración Inicial: Lo primero que debemos de tener en cuenta es el tipo de planta que vamos a introducir en el invernadero, ya que cada tipo soportara distintas temperaturas, humedad, riego, iluminación. Esto lo podemos conseguir mediante un interruptor de 2 posiciones. Recuerde que debe de estar seleccionado el modo de funcionamiento antes del arranque del dispositivo.

Inverduino

• Mensaje de bienvenida: Si todo va por buen camino en la Lcd debe de aparecer durante unos instantes un mensaje de bienvenida, como vemos en la imagen, y posteriormente proceder a la configuración manual si hemos seleccionado esto o a su funcionamiento automático.

• Configuración manual: Durante la configuración manual nos pedirá unos parámetros que debemos de tener en cuenta para la perfecta configuración del dispositivo, según la planta en cuestión. Estos parámetros son: Temperatura mínima, temperatura máxima, humedad mínima, humedad máxima, humedad tierra mínima, iluminación mínima, para posteriormente procesar esta información la unidad de control (Arduino Mega) y activar/desactivar los actuadores según condiciones ambientales. Los parámetros iremos cambiándolos mediante dos pulsadores con uno aumentaremos el valor inicial de 0 y con el otro lo reduciremos por si nos pasamos en algún valor, disponemos de otro pulsador para pasar al siguiente valor como vemos en la imagen.

Inverduino

- Cosas a tener en cuenta: El depósito de agua dispone de un sensor de ultrasonidos que nos informara de su capacidad con lo que cuando se encuentre en un nivel bajo para el funcionamiento de la bomba de agua sumergible activara un buzzer con el nos avisara mediante un tono acústico, por lo que procederemos a rellenarlo. Siguiendo estas instrucciones de funcionamiento mínimas tendrás un sistema autónomo de cultivo para pequeñas plantas.

Dicha información técnica se ha obtenido directamente de los datasheets suministrados por los fabricantes y en ellos se encontrara información acerca de parámetros eléctricos, tamaño, encapsulado, graficas de funcionamiento, etc.

- Protocolo de test Para comprobar el correcto funcionamiento de nuestro prototipo de Inverduino procederemos a comprobar tensión de alimentación de la fuente de alimentación y bomba de agua, como vemos en la imagen debemos de tener aproximadamente 230v, con ayuda de nuestro polímetro en la medida de tensión alterna. Como vemos en la imagen:

Inverduino

• Posteriormente procederemos a comprobar la tensión que nos proporciona la fuente de alimentación, esta debería de ser de 12v DC (cable amarillo positivo y negro, masa) y 5v DC (entre cable rojo, positivo, y cable negro, negativo)

• Arduino mega

The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.

The Arduino Mega2560 can be powered via the USB connection or with an external power supply. The power source is selected automatically. External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.

The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.

The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter.

The power pins are as follows:

• VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.

• 5V. The regulated power supply used to power the microcontroller and other components on the board. This can come either from VIN via an on-board regulator, or be supplied by USB or another regulated 5V supply.

• 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA. • GND. Ground pins.

The ATmega2560 has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library).

Each of the 54 digital pins on the Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions:

• Serial: 0 (RX) and 1 (TX); Serial 1: 19 (RX) and 18 (TX); Serial 2: 17 (RX) and 16 (TX); Serial 3: 15 (RX) and 14 (TX). Used to receive (RX) and transmit (TX) TTL serial data. Pins 0 and 1 are also connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip .

• External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.

• PWM: 0 to 13. Provide 8-bit PWM output with the analogWrite() function. • SPI: 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS). These pins support SPI communication, which, although

provided by the underlying hardware, is not currently included in the Arduino language. The SPI pins are also broken out on the ICSP header, which is physically compatible with the Duemilanove and Diecimila.

• LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.

• I2C: 20 (SDA) and 21 (SCL). Support I2C (TWI) communication using the Wire library (documentation on the Wiring website). Note that these pins are not in the same location as the I2C pins on the Duemilanove.

The Mega2560 has 16 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the AREF pin and analogReference() function.

There are a couple of other pins on the board:

• AREF. Reference voltage for the analog inputs. Used with analogReference(). • Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset button to shields which

block the one on the board.

The Arduino Mega2560 has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega2560 provides four hardware UARTs for TTL (5V) serial communication. An ATmega8U2 on the board channels one of these over USB and provides a virtual com port to software on the computer (Windows machines will need a .inf file, but OSX and Linux machines will recognize the board as a COM port automatically. The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the board. The RX and TX LEDs on the board will flash when data is being transmitted via the ATmega8U2 chip and USB connection to the computer (but not for serial communication on pins 0 and 1).

A SoftwareSerial library allows for serial communication on any of the Mega's digital pins.

The ATmega2560 also supports I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus; see the documentation on the Wiring website for details. To use the SPI communication, please see the ATmega2560 datasheet.

The Arduino Mega2560 can be programmed with the Arduino software (download). For details, see the reference and tutorials.

The Atmega2560 on the Arduino Mega comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).

You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header; see these instructions for details.

http://www.arduino.cc/en/Reference/SoftwareSerial

Rather then requiring a physical press of the reset button before an upload, the Arduino Mega2560 is designed in a way that allows it to be reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the ATmega8U2 is connected to the reset line of the ATmega2560 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line drops long enough to reset the chip. The Arduino software uses this capability to allow you to upload code by simply pressing the upload button in the Arduino environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can be well-coordinated with the start of the upload.

This setup has other implications. When the Mega2560 is connected to either a computer running Mac OS X or Linux, it resets each time a connection is made to it from software (via USB). For the following half-second or so, the bootloader is running on the Mega2560. While it is programmed to ignore malformed data (i.e. anything besides an upload of new code), it will intercept the first few bytes of data sent to the board after a connection is opened. If a sketch running on the board receives one-time configuration or other data when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before sending this data.

The Mega contains a trace that can be cut to disable the auto-reset. The pads on either side of the trace can be soldered together to re-enable it. It's labeled "RESET-EN". You may also be able to disable the auto-reset by connecting a 110 ohm resistor from 5V to the reset line; see this forum thread for details.

The Arduino Mega has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.

The maximum length and width of the Mega PCB are 4 and 2.1 inches respectively, with the USB connector and power jack extending beyond the former dimension. Three screw holes allow the board to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins.

The Mega is designed to be compatible with most shields designed for the Diecimila or Duemilanove. Digital pins 0 to 13 (and the adjacent AREF and GND pins), analog inputs 0 to 5, the power header, and ICSP header are all in equivalent locations. Further the main UART (serial port) is located on the same pins (0 and 1), as are external interrupts 0 and 1 (pins 2 and 3 respectively). SPI is available through the ICSP header on both the Mega and Duemilanove / Diecimila. Please note that I2C is not located on the same pins on the Mega (20 and 21) as the Duemilanove / Diecimila (analog inputs 4 and 5).

Arduino can sense the environment by receiving input from a variety of sensors and can affect its surroundings by controlling lights, motors, and other actuators. The microcontroller on the board is programmed using the Arduino programming language (based on Wiring) and the Arduino development environment (based on Processing). Arduino projects can be stand-alone or they can communicate with software on running on a computer (e.g. Flash, Processing, MaxMSP).

ultrasonic is the sound wave beyond the human ability of 20KHZ .

1.21.21.21.2 UltrasonicUltrasonicUltrasonicUltrasonic distancedistancedistancedistance measurementmeasurementmeasurementmeasurement principleprincipleprincipleprinciple

Ultrasonic transmitter emitted an ultrasonic wave in one direction, and started

timing when it launched. Ultrasonic spread in the air, and would return

immediately when it encountered obstacles on the way. At last, the ultrasonic

receiver would stop timing when it received the reflected wave. As Ultrasonic

spread velocity is 340m / s in the air, based on the timer record tttt, we can

calculate the distance (s) between the obstacle and transmitter, namely: s =

340t / 2, which is so- called time difference distance measurement principle

The principle of ultrasonic distance measurement used the already-known air

spreading velocity, measuring the time from launch to reflection when it

encountered obstacle, and then calculate the distance between the transmitter

and the obstacle according to the time and the velocity. Thus, the principle of

ultrasonic distance measurement is the same with radar.

Distance Measurement formula is expressed as: L = C X T

In the formula, L is the measured distance, and C is the ultrasonic spreading

velocity in air, also, T represents time (T is half the time value from transmitting

to receiving ).

6. Operating specifications:(1) Power and PinsPower's voltage should be 3.3-6V DC. When power is supplied to sensor, don't send any instruction to the sensor within one second to pass unstable status. One capacitor valued 100nF can be added between VDD and GND for wave filtering. (2) Communication and signalSingle-bus data is used for communication between MCU and DHT22, it costs 5mS for single time communication.

Data is comprised of integral and decimal part, the following is the formula for data.

DHT22 send out higher data bit firstly! DATA=8 bit integral RH data+8 bit decimal RH data+8 bit integral T data+8 bit decimal T data+8 bit check-sum If the data transmission is right, check-sum should be the last 8 bit of "8 bit integral RH data+8 bit decimal RH data+8 bit integral T data+8 bit decimal T data".

When MCU send start signal, DHT22 change from low-power-consumption-mode to running-mode. When MCU finishs sending the start signal, DHT22 will send response signal of 40-bit data that reflect the relative humidity

Without start signal from MCU, DHT22 will not give response signal to MCU. One start signal for one time's response data that reflect the relative humidity and temperature information from DHT22. DHT22 will change to low-power-consumption-mode when data collecting finish if it don't receive start signal from MCU again.1) Check bellow picture for overall communication process:

2) Step 1: MCU send out start signal to DHT22

Data-bus's free status is high voltage level. When communication between MCU and DHT22 begin, program of MCU will transform data-bus's voltage level from high to low level and this process must beyond at least 1ms to ensure DHT22 could detect MCU's signal, then MCU will wait 20-40us for DHT22's response.

8. Attentions of application:(1) Operating and storage conditions We don't recommend the applying RH-range beyond the range stated in this specification. The DHT22 sensor can recover after working in non-normal operating condition to calibrated status, but will accelerate sensors' aging.(2) Attentions to chemical materials Vapor from chemical materials may interfere DHT22's sensitive-elements and debase DHT22's sensitivity.(3) Disposal when (1) & (2) happens Step one: Keep the DHT22 sensor at condition of Temperature 50~60Celsius, humidity <10%RH for 2 hours; Step two: After step one, keep the DHT22 sensor at condition of Temperature 20~30Celsius, humidity >70%RH for 5 hours.(4) Attention to temperature's affection Relative humidity strongly depend on temperature, that is why we use temperature compensation technology to ensure accurate measurement of RH. But it's still be much better to keep the sensor at same temperature when sensing. DHT22 should be mounted at the place as far as possible from parts that may cause change to temperature.(5) Attentions to light Long time exposure to strong light and ultraviolet may debase DHT22's performance.(6) Attentions to connection wires The connection wires' quality will effect communication's quality and distance, high quality shielding-wire is recommended.(7) Other attentions * Welding temperature should be bellow 260Celsius. * Avoid using the sensor under dew condition. * Don't use this product in safety or emergency stop devices or any other occasion that failure of DHT22 may cause personal injury.

Soil Moisture Sensor

Overview

What is an electronic brick? An electronic brick is an electronic module which can be assembled like Lego bricks simply by

plugging in and pulling out. Compared to traditional universal boards and circuit modules assembled with various

electronic components, electronic brick has standardized interfaces, plug and play, simplifying construction of prototype

circuit on one’s own. There are many types of electronic bricks, and we provide more than twenty types with different

functions including buttons, sensors, Bluetooth modules, etc, whose functions cover from sensor to motor drive, from

Ethernet to wireless communication via Bluetooth, and so on. We will continue to add more types to meet the various

needs of different projects.

Electronic brick of soil moisture sensor is mainly used to detect the moisture content in the soil. The control board can get

the moisture value or threshold in the soil via analog or digital pins.

Features

1. Plug and play, easy to use. Compatible with the mainstream 2.54 interfaces and 4-Pin Grove interfaces in the market.


, April, 2013

2


2. With use of M4 standard fixed holes, compatible with M4-standard kits such as Lego and Makeblock.

3. With switch to shift between analog and digital output. Able to read the specific soil moisture information (analog) or

the over-wet or over-dry soil information according to the threshold (digital). The adjustable potentiometer is used to

set the moisture threshold.

4. With hysteresis comparator circuit for more stable digital output voltage.

Specifications

PCB size 71.65mm X 24.00mm X 1.6mm

Working voltage 3.3or 5V DC

Operating voltage 3.3 or 5V DC

Compatible interfaces 2.54 3-pin interface and 4-pin Grove interface(1)(2)

Note 1： D for digital output port, A for analog output port, S for analog/digital output port ( defined according to the

switch), V and G for voltage at the common collector and ground respectively

Note 2： When setting as analog output, output range is 0-3.3V or 0-5V according to the working voltage; when setting as

digital output, output is 0/3.3V or 0/5V according to the working voltage.

Switch and indicator

1. Regulating of threshold voltage:

The threshold voltage is a voltage for comparison. When the soil moisture value read by the sensor is above the threshold

value, a low level (0V) will be digitally output; when the soil moisture value read by the sensor is below the threshold value,

a high level (3.3V or 5V) will be digitally output. In this way, the digital pin can be used directly to read the current soil

moisture value to see if it is above the threshold or not. The threshold voltage can be regulated by simply twisting the

potentiometer which is shown in Figure 1., and it increases by rotating to left side and decreases by rotating to right side.

2. Switch to shift between analog and digital output

For 4-pin Grove interface, this switch makes no sense.

For S pin in 2.54mm 3-pin interface, it outputs analog signals when switch is pushed to A terminal and digital signals

when pushed to D terminal. When there is analog signal output, it can read the specific soil moisture value; when

there is digital signal output, it can only indicate whether the soil moisture value is above threshold value or not.

DEMO

1. Push the snap switch of sensor to analog output, connect S port to A0 port of Arduino board, and we will use the

following program to read the analog value of soil and send it to computer for display via the serial port.

int ASignal = A0;

void setup() {

Serial.begin(9600);

}

void loop() {

int sensorValue = analogRead(ASignal);

Serial.println(sensorValue);

}

2. Push the snap switch of sensor to digital output, connect S port to D2 port of Arduino board, and we will use the

following program to read the digital value of soil and send the threshold to computer for display .

int DSIGNAL = 2;

void setup()

{

Serial.begin(9600);

Systronix 20x4 LCDBrief Technical Data

July 31, 2000

Here is brief data for the Systronix 20x4 character LCD. It is a DataVision part and uses theSamsung KS0066 LCD controller. It's a clone of the Hitachi HD44780. We're not aware of anyincompatabilities between the two - at least we have never seen any in all the code and customapplications we have done.

This 20x4 LCD is electrically and mechanically interchangeable with 20x4 LCDs from severalother vendors. The only differences we've seen among different 20x4 LCDs are:

1) LED backlight brightness, voltage and current vary widely, as does the quality of the display

2) There is a resistor “Rf” which sets the speed of the LCD interface by controlling the internaloscillator frequency. Several displays we have evaluated have a low resistor value. This makesthe display too slow. Looking at the Hitachi data sheet page 56, it appears that perhaps the“incorrect” resistor is really intended for 3V use of the displays.

At 5V the resistor Rf should be 91 Kohms. At 3V it should be 75 Kohms. Using a 3V display at5V is acceptable from a voltage standpoint (the display can operate on 3-5V) but the oscillatorwill then be running too slowly. One fix is to always check the busy flag and not use a fixed timedelay in your code, then it will work regardless of the LCD speed. The other option is to alwaysallow enough delay for the slower display.

All Systronix 20x4 LCDs have the 91 Kohm resistor and are intended for 5V operation.

Thank you for purchasing Systronix embedded control products and accessories. If you have anyother questions please email to [email protected] or phone +1-801-534-1017, fax +1-801-534-1019.

Reset Function

Initializing by Internal Reset Circuit

An internal reset circuit automatically initializes the HD44780U when the power is turned on. Thefollowing instructions are executed during the initialization. The busy flag (BF) is kept in the busy stateuntil the initialization ends (BF = 1). The busy state lasts for 10 ms after VCC rises to 4.5 V.

1. Display clear

2. Function set:

DL = 1; 8-bit interface data

N = 0; 1-line display

F = 0; 5 × 8 dot character font

3. Display on/off control:

D = 0; Display off

C = 0; Cursor off

B = 0; Blinking off

4. Entry mode set:

I/D = 1; Increment by 1

S = 0; No shift

Note: If the electrical characteristics conditions listed under the table Power Supply Conditions UsingInternal Reset Circuit are not met, the internal reset circuit will not operate normally and will failto initialize the HD44780U. For such a case, initial-ization must be performed by the MPU asexplained in the section, Initializing by Instruction.

Instructions

Outline

Only the instruction register (IR) and the data register (DR) of the HD44780U can be controlled by theMPU. Before starting the internal operation of the HD44780U, control information is temporarily storedinto these registers to allow interfacing with various MPUs, which operate at different speeds, or variousperipheral control devices. The internal operation of the HD44780U is determined by signals sent fromthe MPU. These signals, which include register selection signal (RS), read/

write signal (R/:), and the data bus (DB0 to DB7), make up the HD44780U instructions (Table 6). Thereare four categories of instructions that:

• Designate HD44780U functions, such as display format, data length, etc.

• Set internal RAM addresses

• Perform data transfer with internal RAM

• Perform miscellaneous functions

HD44780U

191

Normally, instructions that perform data transfer with internal RAM are used the most. However, auto-incrementation by 1 (or auto-decrementation by 1) of internal HD44780U RAM addresses after each datawrite can lighten the program load of the MPU. Since the display shift instruction (Table 11) can performconcurrently with display data write, the user can minimize system development time with maximumprogramming efficiency.

When an instruction is being executed for internal operation, no instruction other than the busyflag/address read instruction can be executed.

Because the busy flag is set to 1 while an instruction is being executed, check it to make sure it is 0before sending another instruction from the MPU.

Note: Be sure the HD44780U is not in the busy state (BF = 0) before sending an instruction from theMPU to the HD44780U. If an instruction is sent without checking the busy flag, the time betweenthe first instruction and next instruction will take much longer than the instruction time itself.Refer to Table 6 for the list of each instruc-tion execution time.

5.2. Proceso de fabricación

- Preparación de componentes: Primero se adquieren los componentes teniendo en cuenta sus especificaciones técnicas, a continuación se obtienen las placas de circuito impreso, basándonos en las pautas anteriores. Como último punto, montaje de componentes en placa de circuito impreso y soldadura. - Obtención de circuito impreso: El material elegido es la baquelita, de 1.7mm de grosor obteniendo así mayor resistencia térmica y a los cambios climáticos y mecánicos. - Soldadura y montaje de componentes en placa de circuito impreso: Se debe tener muy en cuenta la manipulación de los componentes, ya que este material es susceptible a la hora de su transporte e instalación en circuito impreso. Los dos circuitos integrados de nuestro proyecto deben ser instalados en zócalos, para su instalación, también debemos prever el lugar y la indumentaria del personal de montaje, ya que estos pueden acumular cargas electrostáticas.

5.3. Cláusulas sobre garantías, plazo de ejecución, etc. …

Este tipo de cláusulas intentan proteger a las partes de posibles errores de manipulación del equipo diseñado, así como establecer un período de garantía de funcionamiento del equipo. Reconocimiento de los materiales. El cliente queda autorizado a utilizar para el desarrollo de este proyecto los materiales que cumplan las condiciones indicadas en el pliego de condiciones., sin necesidad de reconocimiento previo de la empresa proyectista, siempre y cuando se trate de materiales de procedencia reconocida y suministros normales. Indemnizaciones por daños y perjuicios. El cliente no tendrá derecho a indemnización por causas de pérdidas, averías o perjuicios ocasionados en el desarrollo del proyecto. Será de cuenta de la empresa contratista indemnizar a quien corresponda y cuando a ello hubiere lugar, de todos los daños y perjuicios que puedan causarse por las operaciones de desarrollo y ejecución del proyecto. El contratista será el responsable de todos los accidentes que sobrevinieran durante la instalación del equipo electrónico, de cualquier avería o accidente. Plazos de ejecución. Se indican en el contrato y empezarán a contar partir de la fecha en que se comunique a la empresa proyectista la adjudicación del proyecto. Los retrasos debidos a causas ajenas a la voluntad de ésta serán motivo de prórroga. El retraso en el pago de cualquier valoración superior a partir de la fecha de la misma, se considerará motivo de prórroga por igual plazo Recepción provisional. Una vez terminado el equipo electrónico en los quince días siguientes a la petición de la empresa proyectista se hará la recepción provisional del equipo por la empresa contratista, requiriendo para ello la presencia de una persona autorizada para cada empresa y levantándose por duplicado el acta correspondiente que firmarán las partes. Si se detectasen fallos de funcionamiento, la empresa contratista lo comunicará por escrito a la empresa proyectista para su reparación fijando un plazo prudencial. Periodo de garantía. Como garantía de la bondad de la obra se descontará a la empresa contratista la última liquidación, el 3% del importe total de la obra.

5.4. Cláusulas de índole económica.

En estas cláusulas se suele determinar la forma de pago en las distintas fases del proyecto: Pagos valorados. Mensualmente se hará, entre la empresa proyectista y la contratista, una valoración del proyecto desarrollado, con arreglo a los precios establecidos y con los planos y referencias necesarias para su comprobación. La comprobación y aceptación deberán quedar determinadas en 15 días. Abonos de materiales. Cuando a juicio de la empresa contratista no exista peligro de hurto de los componentes adquiridos para el desarrollo del equipo electrónico, éstos se abonarán antes de la finalización del proyecto según establezcan las partes, no obstante la empresa contratista podrá exigir las garantías necesarias para evitar la salida o deterioro de los componentes abonados.

Inverduino Descuento por equipo defectuoso. La empresa contratista podrá proponer a la empresa proyectista la aceptación de estas taras con la rebaja económica que estime oportuna si se ha observado defectos de funcionamiento en el equipo electrónico diseñado con relación a lo exigido en el pliego de condiciones. Si no quedara satisfecho la empresa contratista con la rebaja quedará obligada al rediseño y construcción de toda la parte del equipo electrónico afectada por los efectos señalados. Revisión de costos. Se revisarán los costos siempre que resulten modificados las condiciones económicas de los costos de materiales en una diferencia superior al 5% al valor prefijado del precio estipulado en el presupuesto. Cuando la empresa contratista requiera la ampliación de alguna de las especificaciones o características del equipo electrónico se deberá realizar un estudio económico del sobreprecio a pagar por la empresa contratista. De no haber acuerdo, la empresa proyectista quedará relevada del compromiso de ejecución quedando obligada al empresa contratista al abono total de todos los costes de mano de obra, y similares desembolsados hasta el momento por la empresa proyectista. Abono de obras. Los pagos valorados se abonarán dentro del mes siguiente a la fecha de redacción. Cualquier retraso sobre estos plazos será indemnizado con el interés oficial para efectos comerciales fijado por el Banco de España. Liquidación definitiva. En el plazo máximo de un mes desde la recepción del equipo electrónico por parte de la empresa contratista ésta deberá realizar la liquidación definitiva. De existir fianza, éste se devolverá en el mes siguiente a la finaliza. 5.5. Cláusulas de índole legal En estas cláusulas se delimitan las condiciones en las que ambas partes podrán rescindir el contrato de construcción del equipo electrónico objeto del proyecto. Modificaciones de obra. El diseño del equipo electrónico podrá ser cambiado total o parcialmente por la empresa contratista, no obstante si la empresa proyectista se considera perjudicada en sus intereses, solicitará la indemnización a que se considere acreedora, y cuya estimación someterán las partes a la decisión de la comisión arbitral. En los casos de suspensión no correrá el plazo. Derecho de rescisión. La empresa proyectista podrá rescindir el contrato en los siguientes casos: 1. Cuando las variaciones introducidas en el equipo electrónico aumenten o disminuyan el importe total de ésta de un 20%. 2. Cuando por razones ajenas a la empresa proyectista pase más de un años sin poder trabajar en el equipo electrónico. 3. Cuando se retrase más de seis meses el pago de alguno de los pagos valorados estipulados. Rescisión por incumplimiento del contrato. En el caso de retraso injustificado sobre los plazos fijados se impondrá a la empresa proyectista una multa de 1,5% del presupuesto asignado como pago valorado. Liquidación en caso de rescisión. Se hará una liquidación única que será la definitiva con arreglo a lo estipulado en este pliego.

Inverduino Cuestiones no previstas o reclamaciones. Todas las cuestiones que pudieran surgir sobre interpretación, perfeccionamiento y cumplimiento de las condiciones del contrato entre ambas partes serán resueltas por la comisión arbitral. La comisión arbitral deberá dictar resolución después de oídas las partes dentro de los quince días siguientes al planteamiento del asunto ante la misma. Durante este plazo, la empresa proyectista deberá acatar las órdenes de trabajo indicadas por la empresa contratista sin perjuicio de proclamar las indemnizaciones correspondientes si la resolución le fuese favorable. Entre las resoluciones dictadas por la comisión arbitral figurará en todo caso la proposición en que cada una de las partes deberá participar en el abono de los horarios de las personas que forman la comisión y de los peritos cuyo informe haya sido solicitado por ella.
