Hi.

The function hal_leds_init() does not work.

What would work is if you can instead initialize all the PINS you're using as output manually for each pin, by using the function nrf_gpio_cfg_output

__STATIC_INLINE void nrf_gpio_cfg_output(uint32_t pin_number)
{
    nrf_gpio_cfg(
        pin_number,
        NRF_GPIO_PIN_DIR_OUTPUT,
        NRF_GPIO_PIN_INPUT_DISCONNECT,
        NRF_GPIO_PIN_NOPULL,
        NRF_GPIO_PIN_S0S1,
        NRF_GPIO_PIN_NOSENSE);
}

Best regards,

Andreas

Hi Andreas, sorry, I am new to this development.

I had redefine the BSP_LED_1 with NRF_GPIO_PIN_MAP(1,1), but the LED still not working.

Btw, I found that the registers for port 1 is different with port 0:

And the code shown:

void hal_leds_init(void)
{
for (uint32_t i = LED_START; i <= LED_STOP; ++i)
{
NRF_P1->PIN_CNF[i] = LED_PIN_CONFIG;
NRF_P1->OUTSET = 1UL << i;
}

is it the reason of not working?

How can i fix this?

Hi.

I think the problem is that in Mesh, you use BSP_LED_1 and so on.

Can you try to redefine BSP_LED_1 with NRF_GPIO_PIN_MAP(1,1) ?

Best regards,

Andreas
