Unable to display messages on Tera Term via USART1 on STM32F429I-Discovery Post edited by ST moderator to be inline with the community rules for the code sharing. In next time please use </> button to paste your code. Please read this post: How to insert source code.
Hello,
I’m using the STM32F429I-Discovery board and trying to display “Hello World” on Tera Term via USART1 (PA9, PA10).
I configured the project in STM32CubeIDE as follows:
USART1 → Mode: Asynchronous
TX: PA9, RX: PA10
Baudrate: 115200, 8N1, No Flow Control
Using the ST-LINK Virtual COM Port (USB connector CN1)
main.c
HAL_Init();
SystemClock_Config();
MX_GPIO_Init();
MX_USART1_UART_Init();
const char msg[] = "Hello World\r\n";
HAL_UART_Transmit(&huart1, (uint8_t*)msg, sizeof(msg)-1, HAL_MAX_DELAY);
while (1)
{
HAL_UART_Transmit(&huart1, (uint8_t*)"Hello Again\r\n", 13, HAL_MAX_DELAY);
HAL_Delay(1000);
}
However, nothing appears on Tera Term.The “ST-LINK Virtual COM Port (COMxx)” is visible in the Windows Device Manager, and I’ve selected the correct COM port in Te
