    Re: A Universal PIC18 Bootloader for PDS

    Hi all,
    I would intend to create a new bootloader that will record only in the upper part of the ROM from a defined address to update the subroutines and many tables written in the ROM.

    Re: A Universal PIC18 Bootloader for PDS

    Hi John,
    The "HRSOut" was the label also for the asm routine that puts the byte into the UART buffer. I think it is better now to avoid confusing.

    Has anyone used this Microchip platform for PIC18?
    Is it essential to use the MPLAB Xpress to program the PIC?
    Can the USB port be used as PC connection => UART?
