Interrupt recursion
My point was is you still use the external interrupt to wake the cpu*Thank You* for letting me know that!  I rewrote the external interrupt as an event capture using the T5...

Interrupt recursion
The comments I made were based on Kartman's statment: disable the interrupt and enable a timer tick interrupt to sample the pushbutton input and debounce properly.I'm going to...

Interrupt recursion
Ok thanks for that, Kartman! disable the interrupt and enable a timer tick interrupt to sample the pushbutton input and debounce properly.I've googled around and searched the...

Dropping UART bits after ATXMEGAA3Bu clock speed change
Ok!  I changed the USART initialization code to look like this: // Initialize usart driver in RS232 mode sysclk_enable_module(SYSCLK_PORT_C, PR_USART0_bm); // set UART...

Dropping UART bits after ATXMEGAA3Bu clock speed change
@ryanfleming > did you recalculate your UART baud value after doing this clock change?   If you mean baud rate as in "bits per second", no, that has not changed.  It...

xmega a3bu cannot change status of a PORT's pins
hi Howard,   hey, thanks for that!  i've swapped in that code, and it works fine.  while i can't judge speed without adding timing code, it certainly looks more...
