Generate any frequency output by PWM

[chianglin]

Hi,

Does nRF52832 can output any frequency waveform by PWM interface? What's the maximum frequency output of PWM?

Which timer is used by PWM?

If I want to use "APP_Timer", "PWM", "ESB" function on the same function, which timers will be occupy?

Thank you,

Chianglin

The datasheet describes the PWM peripheral.

The Application Timer documentation tells you which Timer it uses:  infocenter.nordicsemi.com/.../group__app__timer.html

Hi awneil,

If I use the demo source code ".\nRF5_SDK_15.2.0_9412b96\examples\peripheral\pwm_driver" to create a PWM output, what is the maximum PWM frequency can I set?

And how to set it's parameter to get the maximum frequency?

Thank you,

Chianglin

Have you looked at the documentation?

Have you looked at the code?

Hi awneil,

I had study the source code and try to modify it's setting (for example: change the base clock to 16MHz).  the maximum frequency is about 1.3MHz

How can I get the maximum PWM output when I set the base clock is 16Mhz?

Thank you,
