Can i generate pure sine wave using a PIC. if it is possible, please help me to make sine wave from pic...

 

Not sure that there is such a thing as a pure sine wave. You need to specify important things such as harmonic distortion or harmonic content.

But most essentially, you have to specify the frequency.

You can come close to perfect if the frequency is below 100Hz.

 

I build this one

Work fantastic

 

I want only 50/60 Hz. it is for making a pure sine wave inverter.

 

Good to tell us your application. For DC to AC inverter you do not need a pure sine wave.
A crude step wise function with as few as 8 steps would work.

 

Can i make this using this technique? What are the steps??
