单片机用P1口显示红外遥控器的按键值，单片机的应用(Display the key value of the infrared remote control, microcontroller MCU with P1 port)

利用单片机IO口模拟UART程序,系统用了一个定时器和一个外部中断,外部中断主要是用来检测串口起始位的到来。(IO mouth simulation UART program, microcontroller system with a timer and an external interrupt, external interrupt is mainly used to detect the arrival of the start bit serial port.)

说明：  I2C_SHT21 温湿度传感器测量 I2C 读取SHT21 温湿度传感器 SHT21驱动库有两种操作模式，适合不同操作 自动转换测量模式： 1：启动任意一个测量指令,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值, autoMeasure(float * th); 该函数读取测量得出的数据，并根据数据的类型进行转化，再自动启动下一个类型的测量 指定转换测量模式： 1：先启动一次测量,例如测量温度执行 measureT(); 2：延时200ms 3：读取测量后的数值,例如读取温度执行readT();(2C_ SHT21 temperature and humidity sensor measurement I2C read SHT21 temperature and humidity sensor SHT21 driver library has two operation modes, which are suitable for different operations Automatic conversion of measurement mode: 1: Start any measurement command, for example, measure the temperature and execute measure(); 2: Delay 200ms 3: Read the measured value and Automeasure (float * th); This function reads the measured data, converts it according to the data type, and then automatically starts the next type of measurement Specify the conversion measurement mode: 1: Start a measurement first, for example, measure the temperature; 2: Delay 200ms 3: Read the measured value, for example, read the temperature and execute readt();)
