I'm trying to set up UART with printf()
#include <stdio.h>
UART_HandleTypeDef huart3;
static void MX_USART3_UART_Init(void);
int __io_putchar(int ch)
{
HAL_UART_Transmit(&huart3, (uint8_t *)ch, 1, 10);
return ch;
}
....
// in main
// in while
prinf("UART test\r\n");
// MX generated USART3 init
static void MX_USART3_UART_Init(void)
{
/* USER CODE BEGIN USART3_Init 0 */
/* USER CODE END USART3_Init 0 */
/* USER CODE BEGIN USART3_Init 1 */
/* USER CODE END USART3_Init 1 */
huart3.Instance = USART3;
huart3.Init.BaudRate = 115200;
huart3.Init.WordLength = UART_WORDLENGTH_8B;
huart3.Init.StopBits = UART_STOPBITS_1;
huart3.Init.Parity = UART_PARITY_NONE;
huart3.Init.Mode = UART_MODE_TX_RX;
huart3.Init.HwFlowCtl = UART_HWCONTROL_NONE;
huart3.Init.OverSampling = UART_OVERSAMPLING_16;
huart3.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE;
huart3.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_NO_INIT;
if (HAL_UART_Init(&huart3) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN USART3_Init 2 */
/* USER CODE END USART3_Init 2 */
}
Clock tree from MX
Output in Tera Term window
TT is set up exactly the same as the UART init in the code.
Anyone know whats going on here?
