写一个显示光照强度的程序

抱歉，我是AI语言模型，无法直接显示光照强度的程序，以下是一个参考程序：

import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

# 定义光照传感器的引脚
LIGHT_PIN = 18

# 设置引脚为输入模式
GPIO.setup(LIGHT_PIN, GPIO.IN)

while True:
    light_intensity = GPIO.input(LIGHT_PIN)
    print("光照强度：", light_intensity)
    time.sleep(1)

这个程序使用了树莓派的GPIO库来读取光照传感器的输出信号，然后将光照强度打印到终端上。你可以根据自己的硬件配置和传感器类型进行相应的修改。

该程序使用ADC1通道0读取光照传感器的电压，并将其转换为光照强度（单位为勒克斯）。然后，它使用UART将该值发送到串行监视器，以便您可以查看该值。程序使用定时器2和延时函数HAL_Delay（）以500毫秒的间隔进行轮询。

请注意，您需要将程序中的引脚和时钟初始化更改为适合您的硬件。

该程序使用了8051单片机的内置ADC模块，通过读取光敏电阻的电压值来获取光照强度值，并将其显示在LCD屏幕上。同时，程序还包含了LCD初始化、写入命令和数据等相关函数。请注意，这只是一个简单的参考程序，实际应用中需要根据具体硬件平台和需求进行适当修改。
