We are looking at using the AT91SAM7S64 in a new project. We had previously tried the ATMEGA32, but it turned out to be underpowered for our needs. The program, however, was less than 100 lines of assembly code for the ATMEGA32.
The AT91 does not seem quite as easy to get into as the AVR. I have the AT91SAM7S64-IAR development kit, and am having trouble figuring out where to go next. Most of the resources I find are for C programming and somewhat larger programs.
Essentially, the program will be outputting data over 10 output lines, and needs an interrupt for listening for data to clock on another 8 input lines. That's it. It will all be ideally written in pure assembly.
If anyone can point me to any resources related to small program development for this processor, I would very much appreciate it. I am currently using the IAR software that came with the development kit with the JLink interface.
Thank you.
