    Default Re: PBP command execution time

    I can't, I tried 8MHz but the software said it couldn't keep up and lowered the speed.


    EDIT: So I tried another approach and lowered the OSC speed, but I get INVALID OSC DEFINE whenever I try DEFINE OSC 1 or 2.

    PIC 18F44K22, PBP 2.60c, MPASM v5.49

    Code:
    asm

     __CONFIG    _CONFIG2L, _PWRTEN_ON_2L & _BOREN_SBORDIS_2L & _BORV_285_2L

    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
