mdk5 printf 乱码

honghongbuqi

在 mdk5 里实现 printf 通过 usart1 打印出来， 结果不能打印正确数据， 全部是乱码， 各位大神指点一下。 extern ARM_DRIVER_UART Driver_UART1;  static void Display (void const *arg) {   while(1) {     printf("LCD , AND WAIT 2s!!\r\n");     osDelay (2500);   } } int main (void) {         Driver_UART1.Initialize(NULL, 0);         Driver_UART1.PowerControl(ARM_POWER_FULL);          Driver_UART1.Configure(115200, 8, ARM_UART_PARITY_NONE, ARM_UART_STOP_BITS_1, ARM_UART_FLOW_CONTROL_NONE);            ADC_Initialize ();   net_initialize ();   osThreadCreate (osThread(BlinkLed), NULL);   osThreadCreate (osThread(Display), NULL);   while(1) {     net_main ();     dhcp_check ();     osThreadYield ();   } } int fputc(int ch, FILE *f) {    Driver_UART1.WriteData ((uint8_t *)&ch, 1);   while (Driver_UART1.TxDone() == RESET)   {}   return ch; }
