RE: Frequency Measurement

Take a look at the answer given in this thread, where the frequency is measured by using multiple PPI channels, two TIMER's and the GPIOTE peripheral. I don't think we have any examples doing this in the SDK, but It shouldn't be too difficult to create it yourself.

I would recommend you to follow this approach:

Understand how the PPI works
Understand how the GPIO and the GPIOTE works
Understand how the TIMER works
Take a look at the GPIOTE example and the PPI example and understand how they work
Implement the solution based on the drawing and code given in this thread

If you encounter any problems along the way, please ask! I will assist you till you have a complete solution.

Best regards,

Simon
