Automatic Baud Rate Detection

[NavMicroSystems]

Thanks you all, is there a codes samples can be offered? . . .

Joe,
You are asking too much.

Start small.
Think about how this could be solved.
Steve's approach is something you could start with.

Let's assume the "unknown" device sends out a (more or less) continous datastream
at unknown Baudrate, Parity etc. and there is now way to influence that Datastream.
So there will be no $55 or $AA Pattern you could sync to.
It will be a challenge to detect the comms parameters.

Even worse if the "unknown" device sends out data on request only.

Again,
start small, let your PC transmit data and try to detect it on your PIC.
(and you'll soon see what I mean)

Thank you Ralph,

I understand what you mean; somehow I have short of experience with PDS and PBP compilers. Anyway your advice still appreciates
