here's the revised baud rate test chart 9998
ASM , very impressif code, thanks.
its always better to use the hardware than bit-banged routines and there is nothing better than a ring-buffer to overcome traffic snarls ...
there are some good ideas here https://www.romanblack.com/DTMF/DTMF_alg.htm
Plenty fast, I'd say. At 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...
edited BaudR var word : baudr = 3313 and TRISA = 111110 1st receiving random characters 2nd normal what could be done to avoid the first thanks. 9997
Although it is a low frequency, still a zero cross happens every 156.2 usec for the 3.2KHz signal. Will the pic be fast enough to process that signal? I am sure ZCD and timers will be enough, but...
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,...

when testing baud rate, usualy I start at 300 and up when it stopped working then I set pace = 1 and re-start from the last baud rate tested. 16F690 Xtal 20Mhz set pace to 1 sEROUT2...
