说明：  单片机I/O口控制红外发射管，模拟格力空调遥控器的代码。典型应用：上位机发送一个通用的“开机，温度，模式……”命令，单片机自动发射出和遥控器一摸一样的波形，实现智能遥控器的功能。 (MCU I/O port control infrared emission control, analog Gree air conditioner remote control code. Typical applications: host computer to send a generic &quot boot, temperature, mode ... ...&quot command, microcontroller and the remote control automatically emit the same wave first touch, intelligent remote control functions.)

本作品以MSP430单片机为核心， 基于DDS原理，通过查表方式输出步进量为10HZ，频率为100HZ~2KHZ的正弦波。两路被测信号通过过零比较、异或和低通滤波整流，实现了对相位差的测量，误差小于(This works with MSP430 microcontroller as the core, based on DDS principle, by look-up table output step sizes for the 10HZ, frequency of 100HZ ~ 2KHZ sine wave. Two by the signal zero-crossing comparator, XOR, rectification and low-pass filtering, the realization of the phase of the measurement error is less than)
