Regarding Fpwm Frequency for Arduino Nano using NRF24L01+ #43

Closed AmeerHafez closed 2 years ago

Hello there,

I have used the audio library on arduino nano for quite some time and it works very well. I'm doing this for my project and I'm wondering what is the default PWM frequency for audio sampling on the default output D9?. As well, how to change the PWM frequency or access it from the RF24Audio library?..

The default frequency is 24khz and can be changed by editing the userConfig.h file found in the library folder.

So the PWM frequency is the same as the audio sampling rate?

Yup!
