Celtic Kings Rage Of War Trainer For Igi. AVR-Software The following example programs, which I have developed, are written in C for use with the AVR-GCC compiler. Tested with AVR-GCC ( WinAVR 20060125 or newer) using a AT90S8515-8PC at 4 Mhz and ATmega8 with 1Mhz. For easy downloading, all these examples are available in a single archive: • helloled basic port input/output techniques • walkingled Turns on one LED on port B which walks from bit 0 to bit 7 in intervals of 0.5 sec Uses AVR Timer/Counter1 interrupt to generate the 0.5 sec delay. • flashled Uses Timer/Counter Output Compare Mode to flash a LED with 1 Hz.

• externint Read input port using external Interrupt • pwmdemo Dims a LED using Pulse Width Modulation • test_eeprom Accessing variables stored in internal EEPROM • RC5decode Decodes RC5 remote control codes • test_starterkit Test program for my • externalsram Example using the External Memory Interface available on some AVR. • debounce_keys Demonstrates debouncing eight keys using a timer interrupt. • adc Analog to digital conversion using the built-in ADC of the ATmega8 I have developed the following libraries which can be used with the AVR-GCC compiler: Tested with AVR-GCC ( WinAVR 20060125 or newer) using a AT90S8515-8PC at 4 M hz and ATmega8 at 1Mhz and 4 Mhz. All libraries are open source under the GNU GPL license. • I2C Master Interface This library consists of a C include file i2cmaster.h and an assembler module i2cmaster.S.

It can be used to communicate with I2C devices (serial EEPROM, serial RTC etc) from any AVR device. L • LCD library for HD44780 based LCD's This library can be used to access a HD44780-based character LCD module. The library can be operated in both the memory-mapped mode and in the 4-bit I/O port mode, depending on the value of LCD_IO_MODE in lcd.h.

• UART library This library can be used to transmit and receive data through the built-in UART. AVR Studio compatible Boot Loader This boot loader support the STK500v2 protocol as used by AVR Studio 4.x and allows application firmware to be upgraded at the target microcontroller via a serial link without the use of a ISP programmer. Fits into a 512work boot loader section. Test program for my AVR Starter Kit For testing my, I have developed the following test program, which is already compiled/linked for direct downloading with a programmer.. © Copyright 200 6 Peter Fleury.
