This config looks good to me: - XINST disabled - DEBUG = disabled - Fosc is 1001 (internal osc with clock out on ra6) One advise: Dont use FOSC=0x34 but use FOSCbits.IRCF0 etc. this makes your code more readable and you can find errors easier. > > My problem right now is that all 8 LEDs remain on at the same time as > power is applied to the system.

I have attached a copy of the code in the email. You running with Fosc=8Mhz, since the pic need 4 steps to complete an instruction, the 2Mhz = 8Mhz/4 is ok (see page 23 of the datasheet chapter 2.1). <quote> 7. INTIO1 Internal Oscillator with FOSC/4 output on RA6 and I/O on RA7 </quote> A clock cycle takes 4 / 8Mhz = 5e-7 secs. A delay of 2x500 let your LED blink with a 0.0005 secs or 2kHz. Thats why they seem to be on. They are just blinking very fast. Try it with a bigger, like 65530, delay. So for me everything looks fine now. jan ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
