Hello all, I am working on a project where I need to make an ajustable PWM Curve over time... Any ideas on calculating/ creating a fully adustable ramp ( 10 bit range ) in assembly?
 

If the curve is to be constant, you can store the required duty cycle values in a table, retrieve the values periodically (depending on the required frequency) and then assign them to the duty cycle register. Then filter the output.
