新手,先做个功能,3个按键,每个按键分别控制3个灯循环点亮,使用STC15F204EA,在网上找的程序片段拼的,但是编译不过,好多错误,麻烦大神帮我看看,我到底错在哪了,谢谢...
#include <STC15X.h>
sbit key1 = P3^7;//定义按键端口
sbit key2 = P3^6;//定义按键端口
sbit key3 = P3^5;//定义按键端口
sbit led1 = P1^7;//定义LED1端口
sbit led2 = P1^6;//定义LED1端口
sbit led3 = P1^5;//定义LED1端口
sbit led4 = P1^4;//定义LED1端口
sbit led5 = P1^3;//定义LED1端口
sbit led6 = P1^2;//定义LED1端口
sbit led7 = P1^1;//定义LED1端口
sbit led8 = P1^0;//定义LED1端口
sbit led9 = P2^7;//定义LED1端口
