I have a problem using a PIC18F4550. Here is my code
Code:
DEFINE OSC 20
'rcsta.7 = 0 tried turning usart off but not work
store var byte
number var word
let number = 65531
tx var portc.6
rx var portc.7
led1 var portd.0
led2 var portd.1
low led1
low led2
input rx
high tx
PAUSE 1000
high led1
serout tx, 2, ["Hello"]
pause 500
serout tx, 2, [#number]
start:
serin rx, 2, ["A"], store
pause 1000
low led1
high led2
serout tx, 2, [#store]
pause 1000
low led2
high led1
goto start
end
I am using a terminal program to test serial comms. If I compile for a pic16f871 it works fine, but compiled for a 18f4550 i just get garbage and the pic does not seem to receive anything.
Can anyone tell me what i'm doing wrong please?
