1.STM32CUBE中使用printf

/* USER CODE BEGIN PTD */
// 2023-07-31 使用printf()
#if 1
#include "stdio.h"
#ifdef __GNUC__
#define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
#else
#define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)
#endif
PUTCHAR_PROTOTYPE
{
	HAL_UART_Transmit(&huart1, (uint8_t*) &ch, 1, 0xffff);
	return ch;
}
#endif
/* USER CODE END PTD */

 

2.在MDK中使用printf

// 在usat.c中添加

#include "stdio.h"

/* USER CODE BEGIN 1 */
int fputc(int ch, FILE *f)
{
  HAL_UART_Transmit(&huart1, (uint8_t *)&ch, 1, 0xffff);
  return ch;
}
int fgetc(FILE * f)
{
  uint8_t ch = 0;
  HAL_UART_Receive(&huart1,&ch, 1, 0xffff);
  return ch;
}
