Yes, I always forget about doing this stuff directly in a processor;
providing the frequency of the beep isnt too high (1KHz ish, I
guess), then most small processors will be fast enough to do a
pseudo-DSP tone detection, either doing software PLL, or maybe doing
a filter and detector. Rough and ready is all that is required here.
Or do it for real in DSP, get a DSP starter kit which has all the
hardware for audio capture on board.
All to clever for me by half, though!
Interestingly, BSR for X10 got a patent on doing software detection
of the 120KHz carrier...
