It might be easier to use nrfx pwm driver directly here. Take a look at e.g. this sample here:

https://github.com/too1/ncs-nrfx-pwm-simple-example/tree/master

(It's a 2 year old sample, so there might be some minor changes required to compile it for the NCS version you are using)

the lines in within the block represent 1mhz pwm is on.

Basically, I need to control 2 GPIOS (turn on and off). And cointrol 3 pwm siganls(turn them on and off) to generate the waveform as shown in the figure

Hi,

[quote user=""]I need to control 2 gpios and 3 pwm pins in matter of few microseconds. I am getting 4X the desired time period. [/quote]

Could you describe a bit more what you are trying to implement? You want to generate a PWM pulse or something? or count pules?
