以下是一份简单的C51代码,实现了智能灯控制的功能,使用了三路开关信号、光敏电阻数值、DS1302、超声波模块和LCD1602。需要根据具体的硬件连接情况进行修改。
```
#include <reg52.h>
#include <stdio.h>
#include "lcd1602.h"
#include "ds1302.h"
sbit switch1 = P1^0;
sbit switch2 = P1^1;
sbit switch3 = P1^2;
sbit light = P1^3;
sbit trig = P1^4;
sbit echo = P1^5;
unsigned int adc_value = 0;
void delay(unsigned int n) {
unsigned int i;
for (i = 0; i < n; i++);
}
void init_adc0832() {
ADC0832 = 0x80;
delay(100);
}
unsigned int read_adc0832(unsigned char channel) {
unsigned char i;
unsigned int value = 0;
ADC0832 = 0x08 | channel;
delay(100);
for (i = 0; i < 8; i++) {
ADC0832 = ADC0832 | 0x04;
ADC0832 = ADC0832 & 0xFB;
value = value << 1;
if (ADC0832 & 0x10) {
value++;
}
}
return value;
}
void init_ds1302() {
ds1302_init();
ds1302_set_time(0, 0, 0, 1, 1, 1, 2020);
}
void main() {
unsigned int distance;
char buffer[20];
lcd1602_init();
init_adc0832();
init_ds1302();
while(1) {
adc_value = read_adc0832(0);
if (adc_value > 500) {
light = 0;
} else {
light = 1;
}
if (switch1 == 0) {
light = 0;
}
if (switch2 == 0) {
light = 1;
}
if (switch3 == 0) {
light = !light;
}
trig = 1;
delay(10);
trig = 0;
while(echo == 0);
TH0 = 0;
TL0 = 0;
while(echo == 1);
TR0 = 1;
while(echo == 0);
TR0 = 0;
distance = (TH0 << 8) | TL0;
distance = distance / 58;
sprintf(buffer, "Distance: %d cm", distance);
lcd1602_set_cursor(0, 1);
lcd1602_write_string(buffer);
ds1302_get_time(buffer);
lcd1602_set_cursor(0, 0);
lcd1602_write_string(buffer);
if (light == 0) {
lcd1602_set_cursor(13, 0);
lcd1602_write_string("OFF ");
} else {
lcd1602_set_cursor(13, 0);
lcd1602_write_string("ON ");
}
delay(100);
}
}
```
其中,init_adc0832() 和 read_adc0832() 函数用于初始化和读取光敏电阻的数值;init_ds1302() 函数用于初始化DS1302时钟芯片并设置当前时间;while(1) 循环中,根据三路开关信号和光敏电阻数值来控制灯的状态,同时使用超声波模块测量距离,并在LCD1602上显示当前时间和距离。
