getchar.c

用MSP430F149控制普通射频芯片CC1000的双向通信程序（串口、液晶显示）

#include <msp430x14x.h>

// Simple implementation of the ANSI getchar() routine, reads from UART
unsigned char getchar(void)
{
  unsigned  char rval;
 
  while ((IFG1 & URXIFG0)==0);  //等待接收字符
  rval = RXBUF0;
  return rval;  	        /* Return received character */
}
