how to blink led by using BSP function with gpio pin p0.2,p0.3,p0.4

[amey3]

Hello sir,

              I am using nrf52832 soc with customized board  having  gpio pin  with P0.2,P0.3 and P0.4 used for led blinking for different purposes.The function used for led blinking is BSP function .

When i change the pins in PCA10040.h  files from LED_1 17,LED_2 18,LED_3 19,LED_4 20 to as described below as :

#define LEDS_NUMBER 4

#define LED_START 3
#define LED_1 3
#define LED_2 4
#define LED_3 5
#define LED_4 6
#define LED_STOP 6  

Due to above following changes the led is not blinking .What changes are required so that the led should Blink properly.

Can it be that some of these pins are configurd as UART or SPIM pins? See pca10040.h that you may need to redefine pins that already used for pins 3-6.

hello sir ,

                 Currently i am testing on the development kit board with redefining the pins as 

              #define LED_START 2
              #define LED_1 2
              #define LED_2 3
             #define LED_3 4
             #define LED_4 5
             #define LED_STOP 5  

  The other pins which are configured with same pins are changed which are spi and uart which are changed given the pin as p0.17 to p0. 20.Still i am not getting the led blinking when it goes  in advertise mode.By mistake i have given the start pin as p0.3 but actually it start from p0.2 to p0.5. currently i am testing on the development kit board by using BSP function if it properly working then i tried into my customized board.But my query we can change the LED_pin in development kit board  from P0.17 to P0.20 as P0.2 to P0.5 .The second question is how i can redefine the PCA10040.h so that it is compatible for the led pins i mention in development kit board

What debugging have you done? Does the code "hang" somewhere when executed on your custom board?
