使用STVD编译器，重定义printf函数后，使用的时候报错
下面是程序
#define __GNUC__
#ifdef __GNUC__
#define PUTCHAR_PROTOTYPE int __io_putchar(int ch)
#else
#define PUTCHAR_PROTOTYPE int fputc(int ch, FILE *f)
#endif
PUTCHAR_PROTOTYPE
{
/* Write a character to the USART */
// USART_SendData8(EVAL_COM1, c);
/* Loop until the end of transmission */
// while (USART_GetFlagStatus(EVAL_COM1, USART_FLAG_TC) == RESET);
UART1->DR=(ch);
/* Loop until the end of transmission */
while (!(UART1->SR & UART1_FLAG_TXE));
return (ch);
}
下面是报错内容
