Hi guys,
As of the following drawings.
I have a pic A, and a pic B. my codes run in A, and I have no control of B. They are connected in TTL serial.
I need to send a stream of data (in packet) from A to B. B will simply repeats what it received from A back to A, and also generated it's own data (in packet).
My question is: how can I filter out the data repeated from B to A, I am only interested the data generated within B.
The data stream is very slow, it's about 16kbps.
Thanks guys!!
