hello Guys

I want to know how to generate a sine wave using 16F876A + H-Bridge Driver ??

without using DAC

Use the PWM output, change the duty-cycle with sinusoidal law, then feed the PWM to the bridge switch and put a output LC filter in order to retain only the 1st harmonic.
About the sinusoidal modulation of the duty cycle you can use a look-up table stored inside the micro.

Just a idea.
