Hi Hitsware,
Yes, that is in my application (2x N-channel FET) needed, so I need an invertor for one signal, and a buffer for the other (the 3.3V pico cannot reliably drive anything other than a logic FET, so I will add buffers).
But using 2 buffers (or 2 inverters) you can drive a P channel and N channel combo (half bridge).
Beauty of the PWM is that "soft start" is simply a short basic algorithm controlling the PWM0A from 5% to 49% while controlling the PWM0B from 95% to 51%.
