Hello, I am new to STM32 and need help with UART.
In recent days I have been trying to deploy my own neural network model on NUCLEO-H755ZI-Q development board. Through ST Edge AI Developer Cloud, I have generated my own CUEB IDE project. In the IDE project, it uses USART3. After reading the development board manual, I learned that USART3 communication between TM32H7 and STLINK is enabled by default, but I cannot receive the data sent through the serial port on the PC side.
Then, I used other serial ports such as USART2, USART1 to test serial output, and connected the PC to the development board through a USB to serial port module, but still could not receive data on the PC side.
/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_USART1_UART_Init();
/* USER CODE BEGIN 2 */
uint8_t data[] = "Hello World!\n";
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
HAL_UART_Transmit(&huart1,data,10,1000);
HAL_Delay(1000);
/* USER CODE BEGIN 3 */
}
The value returned by the function is HAL_OK.
I posted the IOC file generated by ST Edge AI Developer Cloud and the IOC file for testing the serial port output. I am happy to get any help and suggestions!
