I have what looks to be a 1.6/3.2kHz FSK signal that I'd like to demodulate to a bitstream using a suitable PIC.
It's a two wire system with bursts of the FSK signal riding on top of the DC supply,...
My code honours the timing as specified by the lcd defines , timing that most lcd displays need esp the cheapest and oldest examples of them.
If you send data at a rate that exceeds the specified...
Here is an example of a neat little solar panel tracker that I built for a NiMh battery charger. I decided to build it for a variety of reasons - - -

Re: FSK demodulator in firmware
Plenty fast, I'd say.
HenrikOlsson Today, 20:42At 32MHz an instruction cycle is 125ns. That's ~1250 cycles between zero crossings.
I'm not trying to interpret/decode the data, just demodulate the signal.
Every other...
