PIC18F2685 config settings for 20 MHz

[wwilson17]

What should the configuration settings be set to for a PIC18F2685 when running a 20 MHz crystal? Right now I have the oscillator set on HS and the watch dog timer disabled. I have DEFINE OSC 20 at the beginning of my program. It seems to be running too fast and it is not seeing my serial input.

Well there's a slight difference in the fuse that may screwup things... there's _OSC_HS_1H and _OSC_HSPLL_1H .

Now how faster it is? Led Blink, serial comm, HPWM are nice start point.

Just post your code here.

I'm using MicroCode Studio to burn the chip and I use the configuration settings provided by the software. Other than that, the only line dealing with the oscillator setting in my code is the DEFINE OSC 20 (PicBasic Pro). I can't post my entire code here because it is over 15,000 lines long. I'm driving a graphical LCD with the PIC. Concerning the header info you showed in your response, what language is that written in?

Well, if you're using PicBasicPro, and this is a PicBasicPro oriented site, then it would follow that the line given above is a PicBasicPro compatible line....in one way or another...

Bookmark it, Hotlink it, read it, then read it again, then read it again after that.
Lots of good info on how things integrate with PBP, assembly, etc.

I've read the thread you suggested. Can't I just establish the proper settings in the configuration listing instead of writting a line of code?

You can modify the *.inc file for the chip ( make a back up for safety)
