nRF52840 and P0.24 output blinking on a PCA10056 board

[STE]

Dear Team,

I'm using a custom board to test a radio module based on the nRF52840 chip, in this board the P0.24 pin is tied to a led that blink during the execution of an SAADC example written for the PCA10056 board. It is possible to know where I can found the led/button settings table for such board inside the SAADC example? There are plenty of function to follow but I need to found where this led is practically driven to understand the right purpose.

Thanks and best regards.

Hello,

Are you using the nRF5 SDK or the nRF connect SDK? If you are using the nRF5 SDK, you can use the GPIO HAL here to drive the LED: GPIO HAL.

e.g.

#include "nrf_gpio.h"

nrf_gpio_cfg_output(24) // Configure P0.24 as an output

nrf_gpio_pin_toggle(24) // Toggle the output.

Best regards,

Vidar
