Functions include getting and setting GMT time, as well as local time. This library provides interrupt-based I2C slave functionality for Atmel 8-bit microcontrollers equipped with a TWI peripheral. Includes a function to identify common I2C devices and special optimizations for AVR devices to allow clock speeds which meet or exceed normal I2C speeds. It is available on PORTB on all of the ICs, whether 28 pin or 40 pin. For general purpose computers, programs written in one programming language can support different hardware configurations. Readers are advised to go through TWI Communication and TWI registers]of ATmega32 before going further. The I2C Slave add on comes with different libraries for different AVR processors.Sensor Test Utility HEX File ATmega32 (Version 1.Avr i2c library asm * * Library procedures for i2c bus (Atmega48) * The library is intended for use as a plug-in * To other projects. Sensor Test Utility HEX File ATmega16 (Version 1.00) Sensor Test Utility Complete AVR Studio Project for ATmega32 Sensor Test Utility Complete AVR Studio Project for ATmega16 If the LEDs are NOT emitting IR then check their connections. The invisible IR rays are easily visible onĬameras. ToĬheck if the IR LEDs are working you can use a Handicam (or any other digitalĬamera like you mobile camera). If the sensors don’t work as expected then please check the connections. If the LCD Does not show any text please adjust the contrast Otherwise I have also provided a HEX file ready to burn to the ATmega32 (orĪTmega16 MCU) and run the Utility in no time. V2.0 then please consult the following documents.

If you don’t know how to compile and burn programs for xBoard You will need these value for calibrating the master robot program. Sensor when NO obstacle is in front of it and when an Obstacle is nearly 6inches It nearer and value should approach 1023. When you bring a Obstacle near one of the sensors the value should go up, bring Screen Shot of xBoard Sensor Test Utility. The screen should show the reading of the 3 sensors as shown below. After That Connect LCD and Sensor Board You made and power LCDWriteIntXY( 10, 1,adc_result, 4) //Print the value LCDWriteIntXY( 5, 1,adc_result, 4) //Print the value LCDWriteIntXY( 0, 1,adc_result, 4) //Print the value Uint16_t adc_result //Array //Wait for LCD to StartupĪdc_result=ReadADC( 0) // Read Analog value from channel-0Īdc_result=ReadADC( 1) // Read Analog value from channel-1Īdc_result=ReadADC( 2) // Read Analog value from channel-2
