GPIOS: Toggle two leds

Toggle two leds every 200ms. We can configure two or more pins from the same port using the same configuration structure, we just need to use the or ( | ) binary operator and the pin definitions

#include "bsp.h"

int main( void )
{
    GPIO_InitTypeDef GPIO_InitStruct;               /*gpios initial structure*/
    
    HAL_Init();                                     /*Init HAL library*/
    __HAL_RCC_GPIOC_CLK_ENABLE();                   /*Enable clock on port C*/
  
    GPIO_InitStruct.Pin = GPIO_PIN_0 | GPIO_PIN_1;  /*pins to set as output*/
    GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;     /*output on mode push-pull*/
    GPIO_InitStruct.Pull = GPIO_NOPULL;             /*no pull-up niether pull-down*/
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;    /*pin speed*/
    /*use the previous parameters to set configuration on pin C0 and C1*/
    HAL_GPIO_Init( GPIOC, &GPIO_InitStruct );
  
    while (1)
    {
        /*Toggle leds connected to C0 and C1 state*/
        HAL_GPIO_TogglePin( GPIOC, GPIO_PIN_0 | GPIO_PIN_1 );
        /*Blocking delay for 200ms*/
        HAL_Delay( 200u ); 
    }
}
