When using the above commands ie. connecting 2 x 08m's together for data transfer and send a "GO" command across to start the 2nd chip going, what is the recommended circuit? The manuals seem full of info for connecting everything else except 2 x PicAXE's or am I missing it?
So if I use Pin 2 (Serial In) do I still need the 22k/10k resistor network or should a 10k to 0v then on to the 2nd 08m which also should have a 10k resistor to 0v?
If I don't use the Serial In can I save space on the board and just use a 33k resistor, as I would not be programming the chip once on the board.
Can I use the same pin for IN/OUTPUT, so chip 1 TX's "GO" then issue a SERRXD, 2nd 08m listening on pin 5, RX's the "GO" command, does some code and then TX's back out pin 5. 1 wire data, but will need a 2nd wire for 0v to common supply. Code should be straight forward but resistors required to stop floating one side or both sides?
Sorry if these questions seem daft.
TIA
