I have wrote and programmed PIC and tested the circuit which very simple yet it wont work,


LED var portb.0
trisb = %11111110
main:
high led
pause 1000
low led
pause 1000
goto main
end

I have tried fused xt and also hs
I hope you can help thanks.

I have done all this before and am now returning but I cant get of square one.
