Can anyone help me to built a sine PWM using 16f877.How to make a sine lookup table.

I am using asm code.Plz guide me.

Hi Raja,
Why beat your head against the wall? What you want to do is basic analog stuff, better done with analog parts, like 555 timers and op amps, they're cheap, available and millions have been used to make what you are making. On top of all that you seem unable or unwilling to use anything but assembly language, and we only do our own homework.
Look at these links if you need to build a function generator, and please use google, keywords Function Generator. Good Hunting !

Hi,

Thanks for the response.

I am not goin to design function generator,I am interest to built a UPS control with PID.

So for that my requirement is adaptive control which means sine and triangular wave .

I am new to PIC so i need some guide to generate sine lookup table and triangular wave generation.
