sbit key1 = p1^0; sbit key2 = p1^1; sbit key3 = p1^2; sbit key4 = p1^3; sbit fmq=p2^1;
sbit key1 = p1^0;
sbit key2 = p1^1;
sbit key3 = p1^2;
sbit key4 = p1^3;
sbit fmq=p2^1;

怎么了
再问：程序编译出错 #include #include #define uchar unsigned char #define uint unsigned int sbit key1 = p1^0; sbit key2 = p1^1; sbit key3 = p1^2; sbit key4 = p1^3; sbit fmq=p2^1; uchar code table[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0xbf,0x0ff}; void jia(); void jian();

#include sbit CLK= P1^0; sbit DIO= P1^1; sbit CE= P1^2; sbit sbit P1_0 = P1 ^ 0; #include sbit a=P1^0; sbit b=P3^2; unsigned int n; void main 单片机c语言 sbit P1_0 = P1 ^ 0; 单片机程序sbit didi=P1^5;是什么意思 #includesbit d1=P1^0;sbit d2=P1^7;void timer0(void)interrup 单片机中地址的分配sbit P1=P1^0,那个P1^0中^0什么意思,有什么作用 sfr p1=0x90 sbit p1_0=0x90 0一样吗 #include sbit p1_1=P1^0; unsigned int a ; void main() {while #include "reg52.h" sbit P1_0 =P1^0; void DELAY(); main() { w sbit P10=P1^0是什么意思啊?请详细说明!谢谢! 51单片机sbit led=P1^0是什么意思?语句里面起什么作用,怎么看的?和sbit CY=PSW^7有什么区别
