    Yes. The analog signal will have to made into a digital value.

    I think with the same pic one can make pwm, with exterior R2R ladder. And of course it is necessary to program the pic.

    With only an alalog signal to wirk with, how will the PIC be able to use the control? Digital numbers are the only thing the PIC can use.

    Yes, a fault. I thought for D/A conversion of a pwm signal from pic
