pcf8592 AD DA C51程序

基于ADT75的c51数字温度读写以及IO口实现模拟i2c通信驱动(ADT75 based C51 digital temperature reading and writing as well as IO port to achieve analog I2C communication driver)

说明：  GY521--MPU6050 Gyroscope Data

金沙滩（KingST）C51单片机的开发板原理图(Principle diagram of C51 development board in Jinshatan)

可以使用keil软件，利用51单片机实现抢答器功能(Keil software can be used to achieve the use of 51 single-chip Responder function)

智能台灯可以根据光照的亮度自动调节亮度，可以保护大人和孩子的视力。(Intelligent desk lamp can automatically adjust the brightness according to the brightness of light, which can protect the eyes of adults and children.)

用51单片机读取AD芯片7135，并显示在1602上，7135是一个高精度低速的AD芯片(With 51 MCU read AD chip 7135, and displayed in 1602, 7135 is a high-precision low-speed AD chip)

TCS3200 RGB颜色采集，可用于检测LED等颜色(TCS3200 RGB color acquisition, can be used to detect LED and other colors)

测量USB电压电流，5秒轮流显示，数字接近5V的为电压，另外一个为电流(Measurement of USB voltage and current, 5 second rotation display)

说明：  通过按键调节PWM输出占空比并实时显示，最小1%最大99%(Adjust the duty cycle of PWM output and display by key-press)

使用NTC热敏电阻进行测温单片机为stc12c5A60s2(Temperature measurement)
