    Re: using the pwm's in pic18f2431-2331-4331-4431

    hello bruce
    i have a doubt abt carrier generation in 18f4431.sine wave ne how il generate through luk up table bt m nt bin able to generate carrier frequency of 20khz to compare it with ma sine...

    Re: parameters on which PIC is selected

    hello mike
    actually what i have in my mind is carrier if 20khz il generate tru microcontroller itself by using the up-dwn counters.my oli problem is hw do i generate 50hz ref to compare it with my...
