Hi Dave,

Thanks. I've done a lot of IR apps with/without external components. Except for the IR LED
and resistor of course.

I just worked up the Data Signal Modulator example while playing with the new 16F1827.

The DSM module on this thing goes well beyond simple modulated IR communications. And
a single resistor + IR LED is all you need to setup an IR wireless network with multiple PICs
all using the hardware USART with HSERIN/HSEROUT.
