/\* USER CODE BEGIN Prototypes \*/
extern GPIO_PinState led\_on(void);
extern GPIO_PinState led\_off(void);
/\* USER CODE END Prototypes \*/

为了支持printf, 直接在usart.c的最下面添加串口的重定向:

/\* USER CODE BEGIN 1 \*/
#ifdef \_\_GNUC\_\_
  /\* With GCC/RAISONANCE, small printf (option LD Linker->Libraries->Small printf
 set to 'Yes') calls \_\_io\_putchar() \*/
  #define PUTCHAR\_PROTOTYPE int \_\_io\_putchar(int ch)
#else
  #define PUTCHAR\_PROTOTYPE int fputc(int ch, FILE \*f)
#endif /\* \_\_GNUC\_\_ \*/
/\*\*
 \* @brief Retargets the C library printf function to the USART.
 \* @param None
 \* @retval None
 \*/
PUTCHAR_PROTOTYPE
{
  /\* Place your implementation of fputc here \*/
  /\* e.g. write a character to the EVAL\_COM1 and Loop until the end of transmission \*/
  HAL\_UART\_Transmit(&huart3, (uint8_t \*)&ch, 1, 0xFFFF);

  return ch;
}
/\* USER CODE END 1 \*/

在main.h添加头文件:
