33FJ128GP310 PLL
PostPosted: Fri Dec 28, 2007 12:40 am     Reply with quote
Hi,
Could anyone please tell me how to setup the dspic33FJ128GP310 to run at 40mhz with a 10mhz crystal. Maybe I'm just dizzy but it runs perfect on the internal osc, but as soon as I try to switch it over to external it all turns to custard. I am running the PR fuse as suggested in another thread, but still it doesn't want to know me,

Thanks Smile

Try the PR_PLL option. This is used for chips that have PLL on the primary oscillator like HS, XT.

Something like
Code:

#fuses HS, PR_PLL, NOWDT
#use delay(clock = 40 M)
