hi,
I am working with two controllers 16f84 and 18f4520. I use my picbasic pro compiler to compile following program. It works fine with 16f84 but does not work with 18f4520. For 18f4520 i have connected just vdd and vss pins. Is the circuit fine??
I also get a warning 230 while compiling the code for 18f4520. I think that is for the configuration bits.
I think my controller is not running at all. Because it cannot have the clock. so, i want to know the configuration bit settings for internal 8Mhz rc oscillator. So, how can i configure them. I use the EPIC programmer given from melabs. So, what should be the option for internal rc oscillator??
whether it should be INTRC Clockout or INTRC??
My very simple code was as below....
-----------------------------code-----------------------------------
OUTPUT PORTA.0
loop: High 0 ' Turn on LED connected to PORTB.0
porta.0 =0
high portb.3
Pause 500 ' Delay for .5 seconds
Low 0 ' Turn off LED connected to PORTB.0
low portb.3
porta.0=1
Pause 500 ' Delay for .5 seconds
Goto loop ' Go back to loop and blink LED forever
End
