Need to know how to start PWM with slow increase in duty cycle(SOFT START LIKE RAMP FUCNTION) slowy increase from 0% to some set duty cycle

[GH M]

code is attached below

You do this by changing the PWM duty cycle by changing the content of respective TIMx_CCRx register.

[GH M]

it should change on its own..

Then use DMA, triggered from the timer's Update event, to reload TIMx_CRRx from a precalculated table upon each cycle.
