    Hi all,

    I have recently designed a program for the PIC12f683. This program takes an input voltage of 0-5VDC and creates a PWM signal on the output. (0V = 0% duty, 5V = 100% duty) so far i have managed to get the output at arround 1000Hz.

    My questions are:

    Is it possible to get a low frequency PWM signal out of a pic??
    Is it possible to use an external clock to create this frequency??


    Any help is greatly appreciated.

    I didnt realise the PIC12F683 had various oscilator frequencies (125KHz - 8MHz). i have set it at a lower one now :D
