if i use this the output freq and wave will be 12hz and modified squr duty= sample * amp_scale duty = temp_math_H ' Taking the High byte is faster than but if i use "duty= sample" the freq and wave for will be okay

here is the GCB file, i'm using proteus for simulating should i post the proteus file?

yes here is the picture

Hi everyone, I'm trying to add feedback, but when ever i add it the modulation frequency ll be dropping from 50Hz to 12Hz and the wave will be modified wave , but if i remove the feedback the modulating frq will be stable to 50Hz and the wave will be clean what will be the solution? chip 16F876A, 16 option explicit config FOSC = HS config WDTE = OFF config PWRTE = ON config CP = OFF config BOREN = ON // ===== I/O ===== Dir PORTC.3 Out ' H-bridge direction A Dir PORTC.4 Out ' H-bridge direction B...

all in zip

Ok, thank you Anobium for the point out ;correction. i have tested it and it works i attached the reading pictures for more verifications
