Hi Steve

I have done the following:
Edit C:\pbp\16F877.INC, Replace _XT_OSC to _HS_OSC

And edit my code as followings:


Include "Modedefs.bas"

DEFINE OSC 20 ' Set the Xtal frequency to 20mHz
RFVDDPin VaR PORTA.3 ' RF Module Power Pin.

Main:
ADCON1 = 7 ' Set Analog pins to Digital.
TRISA = 0 ' Set all PortA Pins as output
high RFVDDPin ' Switch RF Module On.
here:
goto here
end



But with no luck, it is still flickering?
