see this link, you can add CONFIG_NFCT_PINS_AS_GPIOS at c_preprocessor_definitions.

Thanks you very much!

Another question again ^^. Why pin 9&10 of nRF52832 cannot invert like GPIO, their description is "NFC antenna connection" and "General purpose I/O", the default usage of them is NFC? How to change its purpose to GPIO?

HAL is the hardware abstraction layer with bare minimal interface to the peripheral. The driver provides more abstract API and is built on top of HAL (i.e, the driver uses HAL API and builds more features on top of it)

Thank you! I have another question. What's the difference of "I2S driver" and "I2S HAL" while using?

The driver for I2S for example have init function you have nrfx_i2s_config where you can set the interrupt priority.the second argument will plugin your handler when the interrupt handler is called and When stopped, release all buffers, including these scheduled for the next transfer.

I am also cannot see any example configuration about interrupt from the SDK driver.

Hi Susheel,

Yes, I know this document "nRF5 SDK", but don't know how to configure it, such as interrupt entrance address, or just register a callback function.

Best regards,

Sean

Strongly recommend to use the nRF5 SDK drivers to access the peripheral instead of configuring it directly. Using drivers will also help you understand their usage and give you more confidence to configure then directly in future (if you need to)
