    Re: Proton PC PWM library for devices 18F1230, 18F1330, 18F2331, 18F2431, 18F4331, 18

    Hi David
    Thanks
    But my only target was less ambitious..
    i wanted only have a ~5 mV resolution instead of ~20 mV
    with a PWM output to an analog voltmeter 0-5 Volts.
    As it seemed too complicated...

    as CCP2RL is only 8 bit, no way to have a 10 bit value
    still work to do....

    Hi Les
    i tested your file PCPWM_Test.bas with the new PCPWM.inc .
    After compilation and simulation, IT WORKS. :smile:
    After a LPF, i obtain a ramp 0 to 1.25V on PWM 1 and 3,
    and a ramp 5V to...
