Communication between two PicChip

[Charles Linquis]

If you are using the hardware serial port (as I suggest), then the polarity will be wrong for a direct connection to a PC, so that won't work.

If you issue HSEROUT [...] and the port doesn't even toggle, then you have some other problem.

I can some steady activity on the HSEROUT port. Seems to me the receiving end is a problem. I used another picF88 chip in case it would be a hardwire pin problem, but still the LCD is not showing the input. I removed the First LCDOUT and juste the one after the HSERIN and the L:CD is showing blank...

Are you using HSERIN for the receive side?

Just do this -

LCDOUT $FE,$1

Topp:

HSERIN [X]
LCDOUT X

Goto Topp

this is what I have now. the tiny rail of the breadboard seems to be defective, although I tested it with my multimeter and it seems to be conducting, but then if I put the wire from the transmitting pic directly to the receiving chip leg then I could see something on the LCD. that fixed. I am sending 5 or 22 or 85 from the TX pic and I am always receiving 49 on the RX chip....
Mainloop:

Pause 50


Hserin [encoded22]
PAUSE 100

lcdout $FE,1, "input ", bin encoded22
pause 200


goto Mainloop

end

I removed the defines commands for HSERIN, ans used the serout command. It WORKS !!!. But i would like to make the HSEROUT AND HSERIN command works. I still get the number 48 or 49 showing up. sometimes after a minute or so the LCD shows some erratic behaviour, showing a lot oo???oo?? on both of the line.....
any ideas?
