Digital outputs PA6 and PA7 dont work

[programer]

I send the code for PIC 18F97L94 on Fusion PIC Board v8

Digital outputs PA6 and PA7 dont work. I aks kindly for help.

I turned of WDT.

Code: Select all

Hi,

Both RA6 and RA7 are used for the external crystal oscillator, this is why you cannot use in your project.

If you want to use these pins, you can set the internal oscillator as clock source in the project settings thus freeing the RA6/7 pins.

Filip.
