Custom nrf52 gpio toggle

[NJ_B]

Hey guys,

I have nrf52832 custom Bluetooth module. It is stand alone nr52832 module . I just want to toggle any gpio on this module .

Can you guys tell me which library should I use ? Or do I have to develop my own firmware?

Thank you.

Hi,

You can use the GPIO HAL functions to configure and control GPIOs.

#define OUTPUT_PIN NRF_GPIO_PIN_MAP(0, 31)  // P0.31

nrf_gpio_cfg_output(OUTPUT_PIN);
nrf_gpio_pin_set(OUTPUT_PIN);
nrf_gpio_pin_toggle(OUTPUT_PIN);

Best regards,
Jørgen
