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,...

Since this question has come up again, I thought I'd throw this module out to the masses. It is something I worked on a while back, with DT's help. Amid life's other priorities, it got put on the shelf to collect dust.
The basic idea is that by adding the module as an INCLUDE and inserting a couple of commands inside your code, you can have the PIC send timing data to your PC via the hardware serial port. It's made for 18F PICs (although some 16Fs may work too). You also need a timer that is not being used for anything else.
1) Instructions are included, as well as a small example.
2) It worked well for me, and as I recall, DT in testing.
3) Use it however you want.
4) I won't be able to offer much support, but figure there are enough knowledgeable folks around here that can help those who need it.
