Here a simple HelloWorld,
/* Includes ------------------------------------------------------------------*/
#include ''stm32f3xx_hal.h''
/* USER CODE BEGIN Includes */
#include <stdio.h>
/* USER CODE END Includes */
/* Private variables ---------------------------------------------------------*/
UART_HandleTypeDef huart1;
/* USER CODE BEGIN PV */
/* USER CODE END PV */
/* Private function prototypes -----------------------------------------------*/
void SystemClock_Config(void);
static void MX_GPIO_Init(void);
static void MX_USART1_UART_Init(void);
/* USER CODE BEGIN PFP */
/**
* @brief Retargets the C library printf function to the USART.
* @param None
* @retval None
*/
int fputc(int ch, FILE *f){
/* Place your implementation of fputc here */
/* e.g. write a character to the USART */
HAL_UART_Transmit(&huart1,(uint8_t*)&ch,1,1);// 1 tick waiting (1ms) enough for 87us/byte at 115200
return ch;
}
/* USER CODE END PFP */
/* USER CODE BEGIN 0 */
/* USER CODE END 0 */
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();
/* Configure the system clock */
SystemClock_Config();
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_USART1_UART_Init();
/* USER CODE BEGIN 2 */
//HAL_SuspendTick(); // comment because needed for timeout
/* USER CODE END 2 */
/* USER CODE BEGIN 3 */
/* Infinite loop */
printf(''Hello from STM32CubeMX\n'');
while (1)
{
}
/* USER CODE END 3 */
}
Regards,
Régis
