Larsie and CorB,
Thank you again for the code and recommendations.
By the way, larsie, in reference to the LarsRF code example - the uart code not working. If you call uartInit() before RF_init() (in main_acktest.c), then the uart code works. I'm wondering if it may have to do with changing PxSEL after the interrupt lines for the switch (P1.3) have been set.

I'm just glad that P1IE se
