Not getting status of multiple pins configured as output

[Agam]

Hi, I am working on a custom board of NRF 51822 driving multiple leds from pin 21 to 30. I am trying to get and transmit the status of all the pins with help of bsp functions, but I am only getting status of 4 pins. 

I even used but it is giving me the same result. nrf_gpio_pin_out_read(pin_num) 

I used SEGGER_RTT lib to display the result, loop only runs 4 times and does not print anything after that. 

uint32_t status[10];
status[0] = bsp_board_led_state_get(BSP_BOARD_LED_0);
status[1] = bsp_board_led_state_get(BSP_BOARD_LED_1);
status[2] = bsp_board_led_state_get(BSP_BOARD_LED_2);
status[3] = bsp_board_led_state_get(BSP_BOARD_LED_3);
status[4] = bsp_board_led_state_get(BSP_BOARD_LED_4);
status[5] = bsp_board_led_state_get(BSP_BOARD_LED_5);
status[6] = bsp_board_led_state_get(BSP_BOARD_LED_6);
status[7] = bsp_board_led_state_get(BSP_BOARD_LED_7);

for(int i=0;i<10;i++){
    SEGGER_RTT_printf(0, "pinNo:%d- %u _ ", i, status[i]);
}

Please help me in getting status of all the pins and transmit them. 

Thanks.

Hi Agam,

You may have forgot to add the extra defines for the LEDs in your "custom_board.h" file referred to in "boards.h".

(use the correct values for "LEDS_NUMBER" and so on.)  

 

You could still use "bsp", but remember BSP_BOARD_LED_n uses LED "index" and not pin number. (BSP_BOARD_LED_0 == 0)

I would recommend you to use nrf_gpio functions so you can use actual pin number.

Thank you :), It worked
