nrfx

The Bare Metal is set up to use nrfx that comes with the nRF Connect SDK.

In Bare Metal, it is expected that the application uses either the nrfx driver or, if needed, interacts directly with the peripheral register interface (nrf hal).

To learn more, see the nrfx documentation that is distributed as a separate bundle. The nrfx source code is located in ../modules/hal/nordic/nrfx.

Note

The CMake in Bare Metal is already set up to include the source code from nrfx.

To include and start using the nrfx driver:

• Include the interface file, like #include <nrfx_spim.h> for the SPI Master driver.

• Start adding code in your application to set up, initialize, and start using the driver.

To start interacting directly with a peripheral through the register interface:

• Include the interface file, like #include <hal/nrf_gpio.h> for GPIO.

• Start adding code interacting with the register interface (nrf_gpio_pin_write).
