Serin serout problem

[lerameur]

Did you make the changes in post #61?

I saw the new picture. Let me think about this for a couple of minutes...

it updated now

[lerameur]

ok I am gpoing to bed now, see ya tomorrow

[skimask]

it updated now

3 more things to try to get this narrowed down...bear with me....

Try this out now:


'RECEIVE PIC

o, I wil wait a bit,

the receing LCD shows only on the second line, with zerosss.

Are you splitting that program up between the 2 PICs or programming the whole thing into one PIC?

[lerameur]

like on the picture, its 2 pics

i tried this thing but it do not work
loop:
lcdout $fe , $c0 , "Waiting.." , DEC3 try1 , "," , DEC3 try2
try1 = try1 + 1 : temp = 0 : tempf = 0
serin portB.2 , t2400 , [ temp1 , temp2 , temp3 , temp4 ]
if temp1 > temp2 then
Portb.4 =1 ------------putting a led here, maybe lcdout is confusing with serin
pause 500
portb.4=0
else
Portb.3 =1 -----------putting a led here
pause 500
portb.3=0
endif

goto loop
End

Ok I am really going now to sleep, see ya later

I meant are you putting the transmit code into the transmit PIC and the receive code into the receive PIC, not the whole thing into both PICs...

'TRANSMIT PIC = one pic

'RECEIVE PIC = another pic
dont worry, only the part that belongs there
