RE: Please let me know the reason why the PWM sample program cannot output PWM.

Hello,

Other than changing the default pins in your application, did you do any other changes?

Did you try the default pins from the application? And is there a particular reason why you need to use exactly GPIOs P0.09 and P0.10? Please note that these are the default NFC pins. I don't know what DK you are using, but if you are using the nRF52832 DK from Nordic, these GPIOs are not actually routed out to the GPIO headers.

Please see the NFC Interface Antennas section on infocenter.

I just realized that on the bottom they mention pin 11 and pin 12. That should be pin 09 and pin 10. The figures and diagrams are correct. You need to desolder and solder on some resistors on the pcb in order to use the GPIO headers for pins P0.09 and P0.10, in addition to adding the preprocessor definition: "CONFIG_NFCT_PINS_AS_GPIOS" to your project.

Best regards,

Edvin
