That depends on the PIC and its oscillator rate. PR2 sets the period of the carrier and CCPR1L the duty cycle. Read Bruce's article for the details...Since only one pin is needed to output the bursts of IR carrier, you could do this with the 12F683 - the 5 free pins can support 32 buttons. I assume you want this small and battery powered.
