52810 PWM control

[Roland]

I have intention to use 52810's PWM output to drive motor. The timing requirement are critical so hardware PWM is essential, rather than CPU generated waveform output.

I have found some posts on forum discussed about pwm related issue like this link (on 51822 though):

Seems 51822 has some problem when comes to hardware PWM. As 52810 is a new chip and has higher hardware profile in spec, so my question is: is 52810 capable of doing hardware PWM other than GPIO toggling ?

nRF51 has no PWM HW peripheral block, it's more or less SW driven, hence some obvious issues. All nRF52 chips have dedicated PWM HW peripheral block which can run independently (= from pre-set registers) even when MCU and other parts of processor do something else. But indeed you should clarify detailed requirements against nRF52810 chip specification...

Thank you @endnode

I will read more about the spec.
