Lets just stick to GPIO

1. I am trying to initialize multiple input buttons and multiple output LEDS.

2. I am trying to glow the LEDS with corresponding buttons. ex:- button 0 glows led0 and so on.

   // Here i can only initialize single input and output But not multiple one. #ifdef BSP_LED_0 #define GPIO_OUTPUT_PIN_NUMBER BSP_LED_0 /**< Pin number for output. */ #endif

   #ifndef GPIO_OUTPUT_PIN_NUMBER #error "Please indicate output pin" #endif

   #ifdef BSP_BUTTON_0 #define GPIO_INPUT_PIN_NUMBER BSP_BUTTON_0 /**< Pin number for output. */ #endif

   #ifndef GPIO_INPUT_PIN_NUMBER #error "Please indicate output pin" #endif

   #define BSP_LED_0 #define BSP_LED_1 LED_2 #define BSP_BUTTON_0 #define BSP_BUTTON_1 BUTTON_2

   int main(void) {

    while(1)
    {
        
        if(BSP_BUTTON_0 == 1) // Here I am facing error every time
        {
            nrf_gpio_port_pin_toggle(BSP_LED_0);
            nrf_delay_ms(500);
            
   
        }
    }
   

   } Explain my mistakes
