pic 2 pic pic'n my brains out!

[earltyso]

Hello all,
I have been multiplexing a keypad to my hyperterminal with no problems!
Now I am trying a more simple program from PIC-2-PIC with no success. I have checked all the basics, ADCON settings, baud rates, modes, qualifier and I am stumped. I have included my code in hopes I made a simple mistake someone with more experience will find.

'transmitter pic16f628a
CMCON = 7
include "modedefs.bas"
'all other i/o info
intro:'...all my other stuff
main:
while switch = 0
serout portb.5,n2400,["A",#55] 'I am sending the decimal value 7 to portc of the other pic
pause 1
wend
goto intro
end


'reciever pic16f877
adcon1=7
include "modedefs.bas"

'all other i/o info

main:
serin porta.0,n2400,["A"],B0 'A is the qualifier , then store a decimal number in B0
portc=B0' send 7 to port c so I have C.0, C.1, C.2 leds come on
got main

thanks,

is it possible to post the whole codes and OSC speed?

And post your code in code boxes

[code]
paste your code here
[/code]

this will looks like

       paste your code here

so your codes stay indented.. more readable.

serout portb.5,n2400,["A",#55] 'I am sending the decimal value 7 to portc of the other pic

From the manual

3) A numeric value preceded by a pound sign ( # ) will send the ASCII representation of its decimal value. For example, if W0 = 123, then #W0 (or #123) will send '1', '2', '3'.

I have been wondering how to post code in box form for a while...

'transmitter side pic16f628a

OUTPUT PORTB.5
OUTPUT PORTA.0
SWITCH VAR PORTB.0
Buzzer VAR PORTB.5
x VAR BYTE

INTRO:
for x = 0 to 1

pause 50
low buzzer
pause 50
next x

main:
while switch = 0
        SEROUT PORTB.5,N2400, ["A",#55]
        PAUSE 1
WEND
GOTO INTRO
END

As this is only a test, I just want to see something on my pcb to show that I have good serial data coming in (leds on portc) then I will move on to LCD text input output from pic16f628a multiplexed keypad...
thanks for the help with the text boxes!

So your serial data is on the same pin as your Buzzer?

Did you set HS_OSC fuse for your F877?

Your PIC16F628 use the internal OSC? Sure the Config fuses are set for it?

As Dave suggested, you want to make sure your qualifiers match on Both Side. Two way here.. or you change #55 to 55 in your SEROUT line, or you change B0 to #B0 in your SERIN line.

Looks like my reply did not come through,
yep I made some dumb mistakes....including, forgetting to set clock to HS on the 877, setting the correct output for my serial data on the 628a, and the way my data was sent #...thanks alot for the help

I am wondering...can you send serin/serout without using a qualifier?
