Communication between two PicChip

[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....

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

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
