Communication between two PicChip

[Charles Linquis]

Do you have your TX pin set for output (TRIS = 0)?

[lerameur]

i ADDed this after I sent the code yesterday.:
TRISB = %00000000
AND

the other pic:
TRISB =%11111111

could it be in the include file?

If you are talking about "modedefs.inc" no. You do not need that file for what you are doing so it is not doing any harm. It is for SERIN/SEROUT and a couple other commands.

Have you tried sending/receiving to a PC?

[lerameur]

nO DID NOT SEND TO pc. Actually never done that in my life....

[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...

[Charles Linquis]

Are you using HSERIN for the receive side?

Just do this -

LCDOUT $FE,$1

Topp:

HSERIN [X]
LCDOUT X

Goto Topp
