Me thinks this will be of interest to you.

And changing

START
SEROUT PORTB.4,N2400,["1234"]

to

START
N = 1234
SEROUT PORTB.4,N2400,[DEC N]

might help

Much simple... your SERIN line is wrong

SERIN PorPin, Mode, Variable

Using the square bracket says you want to wait a specific character..

INCLUDE "modedefs.bas"
M VAR BYTE
pause 500
START
        SERIN PORTB.5,N2400,#M
        lcdout $FE,1,#M
        GOTO START

if you send 1234... it will never fit in a BYTE variable.. max=255...

Leave your transmitter code as is, but change 1234, to 123 for now to see what happen.


PS: DEC modifier should not work for SEROUT, but for SEROUT2 .

have a look here, esp. post 16:http://www.picbasic.co.uk/forum/show...highlight=cren

Thanks to everyone for the quick replies. I havent had chance to try the corrected code as yet, Ill post back when I get chance.

Ok I now have a working prototype, thanks to all that contributed.
Transmitter:

INCLUDE "modedefs.bas"
N VAR BYTE
FOR N=0 TO 255
serout PORTB.0,N300,[N]
TOGGLE PORTB.1
PAUSE 100
NEXT N

Receiver:

INCLUDE "modedefs.bas"
N VAR BYTE
PAUSE 1000
START
LCDOUT $FE,$C0,"SERIAL RECEIVER"
SERIN PORTB.4,N300,N
LCDOUT $FE,1,#N
PAUSE 50
GOTO START

Hello,

You can put the schema to understand it better.

Thank you
