uart发送和接收字符串(可proteus仿真)(共2页).doc

/此程序主要用于uart发送字符和字符串(proteus终端不能显示汉字，但串口助手可以),输入换行符结束#includevoid uart_init(void);/串行口初始化unsigned char getbyte(void);void sendbyte(unsigned char c);void sendstring(unsigned char *string);void getstring(unsigned char *string);int main(void)unsigned char c,string100;uart_init();while(1)/发送字符c=getbyte();sendbyte(c);/换两行sendbyte(r);/r为终端换行符sendbyte(r);/发送字符串getstring(string);sendstring(string);
