I'm using AD9833 to generate sine, triangle and square wave. Square from IC has 0,65V amptlitude and 50% duty cycle. I would like in simple way change duty cycle this square signal from 0-100%. Using potentiometer or uC. I have only one ideas, generate PWM from uC, but AD9833 is easier to control frequency.
edit I designed this layout I want use 3 potentiometer to set duty cycle, ampltiude, and signal offset. You can check the correctness? In spice everything is okay. V1 and V3 is AD9833 output
