飞思卡尔的键盘中断源代码,C语言写的,很不错的

#include "GP32C.H"          //MCU头文件
#define ReSendStatusR SCS1  //SCI状态寄存器    
#define ReTestBit     5     //接收缓冲区满标志位         
#define SendTestBit   7     //发送缓冲区空标志位     
#define ReSendDataR   SCDR  //数据寄存器 
//串行接收与发送函数声明
unsigned char SCIRe1(unsigned char *p);  //接收1字节
unsigned char SCIReN(unsigned char n,unsigned char ch[]);  //接收n字节
void SCISend1(unsigned char o);          //发送1字节
void SCISendN(unsigned char n,unsigned char ch[]);         //发送n字节
