PostPosted: Sun Sep 04, 2005 9:35 am     Reply with quote

Hi there,

i jut use the floowing commands to operate my PIC at 48MHz.

#fuses HSPLL,NOWDT,NOPROTECT,NOLVP,NODEBUG,USBDIV,PLL5,CPUDIV1,
VREGEN
#use delay(clock=48000000)

I was supposed to flash a led through A5 once in a second, but it flashes once in approx. 3 seconds. When i set

#use delay(clock=48000000)

everything is fine! Can you help me? What am i doing wrong?

Power off and then back on. You have to do this when you set the PLL.
