18f4520 serial communication

[skimask]

Thanks Steve,
It is connected to a MAX232 . OSC is at 4 mhz. didnt know about the serial communicator. Nice toy. Still learning. But not giving up.

Thanks for taking the time to reply.

Didn't you say earlier you were using C.6 for TX and C.7 for RX?
Your code says exactly the opposite...

--> My circuit board uses portc.6 for tx and portc.7 for rx.

--> Serout PORTC.7, N2400, ["test"] ' Send string

You need to use non-inverted serial mode if you're going through the max232.

ok, i did have the incorrect pin. Thank you
second, i needed to change to T2400. Thank you

I will try to review my work closer in the future. Didn't see these.

It is now working. One more question.


include "modedefs.bas"


print:
Serout PORTC.6, t2400, ["test"] ' Send string
pause 100 ' pause 1/10 sec
Goto print ' Forever

end


If i was to use this statement how would the con be stated? SO con PortC.6. It does not compile with this. What should be here. I would think that i need to state port and bit.

SO con portc.6 ' Define serial out pin

PBP automatically makes the pin an output.

Serout PORTC.6 tells PBP which port & pin to use. You can't declare a port
pin as a constant.
