PIC microcontrollers

Aug 01, 2006 3 Replies

I'm looking to get started using PIC microcontrollers and was looking for a good forum for discussing the basics. Questions like, given that I want to run an PIC18 microcontroller at 40 MHz, for the external clock, would it be better to use a ceramic resonator or a crystal (presumably with the required parallel resistor and two capacitors).



So, is this the right newsgroup? Are there better online forums for this topic?



Thanks, Jeff


Most of the PIC 18 chips, _will not_ run at 40MHz, with an external crystal or resonator (they will with a complete external oscillator). The maximum internal oscillator frequency is usually 25Mhz, but the chips have a *4 PLL, and you run the oscillator at 10Mhz, with the PLL enabled,to have the chip run at 40MHz. A crystal will be more accurate in general, the resonator will be cheaper. Microchip have a fairly good forum. Particular software development tools/kits, will have their own sites.

Best Wishes
