    Hello everybody I would like to control an AC motor (three phase),with a potentiometer connected to an RA0 of the PIC18F46K22,the potentiometer is used for setting the frequency of the sine wave signal which is used for controlling the H-Bridhe (Six MOSFET),can anybody help me to implement the multiplication operation so that the ratio V/F remain constant for all operating period?

    I would like to be using the PIC18F46K22 with C language (MicroC or ccs c compiler),the three phase signal has been implemented but the integration of a potentiometer which allows the variation of F which leads the change in voltage is a problem.

    Please help,
