    Re: 18f25k42 pps

    I wrote a library for the PIC18FxxK40 series based on Les' code. It could be possible to use it for the K42 series. Just check the 2 datasheets and seee the differences.

    HPC Development Board DM164136

    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?
    Thanks for the info.
