Hello:
Has there been any desire or efforts to include the dead time for PWM signals in 16 bit pics?
If not then:
Any future thoughts for this?
Any ideas on implementing dead time?
I believe that a significant amount of hardware and thought is required in order to allow H bridge transistor shutoff time to occur,
Thoughts?

Re: PWM Dead time
Hi
This gives a basic overview of H-Bridge for those unaware of the potential problem
https://www.allaboutcircuits.com/techni ... -time-pwm/
Microchip have a lot of resources regarding control and implementation and many PICs have programmable Dead Band

This also give a little insight on calculation using switching times of MOSFETS

Re: PWM Dead time
Hi
Outputs > DC Motor has properties for using hardware H-Bridge that include setting dead band values. I've not used it though.
