以上引脚都有对应的寄存器可以控制其输入和输出。使用时需要根据实际的外设或存储器进行配置。
#include <reg51.h>
// 引脚定义
sbit P0_0 = P0^0;
sbit P0_1 = P0^1;
sbit P0_2 = P0^2;
sbit P0_3 = P0^3;
sbit P0_4 = P0^4;
sbit P0_5 = P0^5;
sbit P0_6 = P0^6;
sbit P0_7 = P0^7;
sbit P1_0 = P1^0;
sbit P1_1 = P1^1;
sbit P1_2 = P1^2;
sbit P1_3 = P1^3;
sbit P1_4 = P1^4;
sbit P1_5 = P1^5;
sbit P1_6 = P1^6;
sbit P1_7 = P1^7;
sbit P2_0 = P2^0;
sbit P2_1 = P2^1;
sbit P2_2 = P2^2;
sbit P2_3 = P2^3;
sbit P2_4 = P2^4;
sbit P2_5 = P2^5;
sbit P2_6 = P2^6;
sbit P2_7 = P2^7;
sbit P3_0 = P3^0;
sbit P3_1 = P3^1;
sbit P3_2 = P3^2;
sbit P3_3 = P3^3;
sbit P3_4 = P3^4;
sbit P3_5 = P3^5;
sbit P3_6 = P3^6;
sbit P3_7 = P3^7;
int main() {
// 配置引脚
P1_0 = 1;
P1_1 = 0;
// 读取引脚状态
if (P2_0 == 0) {
// ...
}
return 0;
}
以上代码演示了如何通过8051微控制器的引脚配置和读取,具体的使用方式可以根据实际的应用场景进行调整和修改。
