Difference: http://www.piclist.com/techref/diff.asp?url=H:\techref\atmel\avr\index.htm&version=1 ON 20040214@10:23:45 PM at page: http://www.piclist.com/techref/atmel/avr/avrbot.htm#38031.9331597222 James Newton[JMN-EFP-786] Says This is a quick test for the AVRbot board. Briefly, you navigate the robot
via q,a,z,w,s,x keys, sent through RS-232 interface.

q - turn left motor forward
a - turn off left motor
z - turn left motor backward

w - turn right motor forward
s - turn off right motor
x - turn right motor backward



The provided hex file is for a 11.0592 MHz crystal and 115200 RS-232
communication . Please take a look at main.h and main.c and adjust it to your
needs. Then recompile with avr-gcc. Note that this is built as a development
board. You access most of the controller's peripherals through header JP5.
It's up to you if you want to improve the system. Or you can wait until I
finish mine as I will publish both schematics for sensors and software for
handling them.

You must provide a TTL (0-5V) level to the AtMega128 serial channel. Connect
to RXD and TXD. Some new PC mother boards automatically detect 5V and in this
case you won't need MAX232 to convert levels. Be aware that if your mother
board doesn't support this detection you will blow the controller. You have
been warned.

If you have questions, read the source code. If still in trouble you
can write to dinux at mail dot bg.
