Loaded up my first program to my ATmega644P board today. Its just a simple program to set Pin 0 on port B as output and then loop forever toggling the the pin as high and low with a short delay in between.
Board setup and scope output.
The code is not so interesting so I wont bother posting it here. Its nothing that can not be seen in any other beginner tutorials for AVR micros around the net.
I will be doing some experimenting with the Analog-to-digital converter and dual USART ports on the ATmega644P that will probably be a bit more interesting.
