Hello everyone,

I have good news !

it's finally work fine let me explain my mistakes.

Changed :
CONFIG FOSC = HSHP ; HS oscillator (high power > 16 MHz) (need External Xtal)

for :
CONFIG FOSC = INTIO67 ; Internal oscillator block (Internal OSC)

and all the pin signals shows up on the scope.

I like to thanks everyone here for your excellent support, and also Charles Leo from MELabs.

Just one more question about the LAT and @ NOP instruction I'm not familiar with theses instructions where can I find
documentations, and does it work with all PIC or just for a family of PIC like this one PIC18F25K22.


Here's the scope results with 2 set of code.
