The objective if the lab will be to redirect printf to USART2 which is connected to ST-LINK Virtual COM port on your Nucelo board.
We will then use the terminal in the STM32CubeIDE to view the printf output.

*Code to be added:*
in main.c:

/* USER CODE BEGIN PFP */
#define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
/* USER CODE END PFP */
////////////////////////////
while (1)
{
printf("** Hello World ** \n\r");
HAL_Delay(1000);
/* USER CODE END WHILE */
/////////////////////////////
/* USER CODE BEGIN 4 */
PUTCHAR_PROTOTYPE
{
HAL_UART_Transmit(&huart2, (uint8_t *)&ch, 1, 0xFFFF);
return ch;
}
/* USER CODE END 4 */
