The reference firmware is targeted for the Microchip C18 compiler and will not work with other PIC compilers without alteration. U can reply in my mail hryroses yahoo. And so it was started practically without problems.

In addition, the firmware now allows the user to access the AN0-AN4 analog pins for monitoring and data acquisition. This work fine to. Display posts from previous: S thanks a lot!! September 25, at 5: The PICkit 3 is not recommended for new designs.
