Hi, I am curious if anyone here has written any software that interfaces to an fsk 4-Level decoder circuit such as this: Image:4levfsk1.gif - The RadioReference Wiki
Specifically, I am trying to determine how to translate the output of the dataslicer to ones and zeros. My loose understanding is that the dataslicer converts the possible combinations of 4 (or 2) frequencies to a voltage level which raises various combinations of the 3 output pins. I think it should be relatively easy to read data in from the slicer with an Arduino, I know that several different pieces of software use this same circuit. I don't care about formatting or the protocol coming in at this time, as long as I can convert the decoder output to ones and zeros.
Thanks,
