NUCLEO-55WLJC1: Most Elemental HAL Functions Don't work
Hey guys, I'm Working on the NUCLEO-55WLJC1 Board. My Problem seems very simple but I've been struggling with this for some time now. I want to use HAL_GPIO_TogglePin To toggle a pin, but it has no effect at all. I tried to use HAL_GPIO_WritePin instead, which doesn't work either. So I meassured the Voltage of the Pin and this is how it looks like:
I thought there might be something wrong with HAL_Driver, but since I'm working with the Device Configuration Tool of the STM32ide everything was initialized from the start.
static void MX_GPIO_Init(void)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};
/* GPIO Ports Clock Enable */
__HAL_RCC_GPIOA_CLK_ENABLE();
/*Configure GPIO pin : RelayS_Pin */
GPIO_InitStruct.Pin = RelayS_Pin;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
HAL_GPIO_Init(RelayS_GPIO_Port, &GPIO_InitStruct);
}and in the main i do nothing but setting/Toggling this Pin:
int main(void)
{
/* USER CODE BEGIN 1 */
/* USER CODE END 1 */
/* MCU Configuration--------------------------*/
/* Reset of all peripherals, Initializes the Flash interface and the Systick. */
HAL_Init();
/* USER CODE BEGIN Init */
/* USER CODE END Init */
/* Configure the system clock */
SystemClock_Config();
/* USER CODE BEGIN SysInit */
/* USER CODE END SysInit */
/* Initialize all configured peripherals */
MX_GPIO_Init();
/* USER CODE BEGIN 2 */
HAL_GPIO_WritePin(RelayS_GPIO_Port, RelayS_Pin, GPIO_PIN_SET);
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_4);
HAL_Delay(5000);
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}I got no clue where i might have gone wrong.
Please Help! Thank You in advance!
