setup_ocillator
PostPosted: Sat Dec 30, 2006 10:16 am     Reply with quote

can anyone prvide clarification on the setup_oscillator function?
I am using a PIC18F4680 and trying to use the iternal oscillator at 8MHZ and use the PLL to clock it up to 32MHZ.
using the CCS constants in setup_oscillator doesn't seem to work. However setting the registers manually does seem to work. If I want to run @ 32Mhz immediately when should I call setup_oscillator?

What compiler version?.
On 3.249, if you call 'setup_oscillator(OSC_32MHZ);', it works OK.
It also does it OK, if you just define the fuse as 'INTRC', and on the next line set the clock as 32MHz.
With either (or both) of these, it correctly sets the PLL enable bit, and sets the oscillator to 8Mhz.

Best Wishes
