After several consecutive days of preparation, the Android mobile phone code has finally been completed. At present, the remote control of the infrared remote control electrical equipment in my dormitory, home, and control room has been completed, in addition, I remotely controlled my D7000 camera, and it was finished.
The code is classified into two types:
Various TV, camera, and other remote control codes are the simplest. You only need to copy the key code and directly convert it into a mobile phone launch code. (In this encoding mode, a single key only emits a single message)
The most difficult part is the air-conditioning code, because the air-conditioning code is to transmit all the control information for a single key, such as increasing the temperature for a certain time, and to transmit all the information such as the control mode, temperature, air volume, and so on together, there is also a verification code. After a long experiment, if the device that imitates the remote control (such as the universal remote control) code is to save the various combinations separately, it will be very long and troublesome, however, the first method is easy to implement. The second method is difficult to find the rule, and it is troublesome to convert the code into a combination in the program and then an android launch code.
After exploring the Gree Remote Control Coding rules as follows (the previous information was collected online and summarized here ):
