xmega + freertos + c problem
So is the variable "c" referenced only in task_a()? Are you trying to use it in the ISR? If you are trying to use "c" in an ISR, it must be a global. Stu

xmega + freertos + c problem
Haven't been in for more than a year, poke my head in just to see how things are going, and here's a question I think I can answer. Take a look at the code generated for task_a...

AVR port I/O changing timing
I'm guessing that an AVR (1) is something in the ATtiny series. That series, while small, is better suited to low part-count applications. Adding a parallel 32 K x 8 bit SRAM is...

AVR port I/O changing timing
You are using what AVR chip? "n AVR (1)" is not anything I know about. "design calls for a 32 Kb memory" -- external memory, I presume. "ports will be changing very fast" - well...

Asynchronous Serial TX
I was going to post my standard UART debug tutorial, but since you are using CodeVision and my canned rant is for GCC, I didn't. However, now that you've posted the problem with...
