NRF52832 PWM limitations

[Gustavo Corrente]

Hello,

With sdk13 and app_pwm library, I only got 9bits resolution for 32KHz freq.

The pwm should have 16bits resolution, with max freq 100KHz? please could anyone confirm that.

Nope: Base PWM frequency is 16MHz. 16MHz/32khz = 500. Those 500 are just short of 9bits=512.

More bits would require a lower PWM frequency.

Turbo is correct. If you need 16-bits resolution the maximum frequency would be no more than 244 Hz ;)
