Re: three level pwm using pic

Hi... thanks for all your guides.... after read the datasheet, i found out that the pic allows analog input, for the comparator mode... so this means that i can directly supply analog input to the pic and the comparator will do it works...rite??... and i just need to do some delay to the pic...the q...

Re: three level pwm using pic

hi.... what is stabalizing cap means?? and one more thing, how does the output of the p16f628 is like,i.e is it in 8 bit output or its output in serial bit.... im doing the lookup table....does each of the data occupy one memory add???or the memory location is replaced from one data to another; this...

Re: three level pwm using pic

hi.. thanks a lot for the link... the project that im doing rite now requires me to use the pic for the switching scheme for my inverter... so..in order to 'on' or 'off' the switches, i need to use the pwm method...i need to generate 3 level pwm by using sine wave and two triangular wave... currentl...

Re: three level pwm using pic

hi..
if we use the comparator to generate pwm,it is possible that we use external source rite...for instant if we use sine voltage,then we dont need sine lookup table anymore rite??

Re: three level pwm using pic

Yeah..thanks a lot...
does the triangle lookup table also use the same method as sine table.
how to program it using assembly language?
and one more thing..what is actually flowcode... :?: :!:
