Question
How to init GPIO on CubeMX generated code ?
Posted on April 26, 2015 at 11:42
Guys,
I have generated a code for Keil from CubeMx but I can't initialize GPIO, I can see a code in main.c below....anyone knows how to initialize GPIO,reset and set a bit on it at CubeMx generated code ?? I used LwIP,USB and RTOS and FatFS...HAL_GPIO_Init(GPIOE, GPIO_CR_CNF_GP_OUTPUT_PP );
/* USER CODE BEGIN 5 */
/* Infinite loop */
for(;;)
{
HAL_GPIO_WritePin(GPIOE,5,0);
osDelay(2000000);
HAL_GPIO_WritePin(GPIOE,5,1);
osDelay(2000000);
osDelay(1);
}
/* USER CODE END 5 *//**
