Teach you how to make an infrared remote control

Suddenly interested in infrared remote control in recent days, so the Internet mixed a bit and found that there are several encoding methods, and there are many different details of the same encoding, in order to find out what remote control is coming from, helpless There was no such thing as a logic analyzer or the like that could not be reached at hand, and Meng had an impulse to write this software.
The circuit diagram, lower computer and upper computer software and related source programs are all put in a compressed file. If you are interested, you can refer to it. Of course, if a master wants to laugh, he may also wish to look at it to act as a joke after the meal.

Finally, briefly explain the use of software. Turn on the power, open the upper computer software, press the "start acquisition" button, this time the software is waiting to wear the next machine's data. Because the lower unit is triggered by a low level, press the button on the remote control to start collecting data for about 10 seconds and display it. When the mouse moves in the waveform window, there will be a straight line following it, and the length of time that appears relative to the first trigger pulse will be displayed. When clicking in the waveform window, a reference line will be left at this point. If you move the mouse to another position and then click it, the length of the line relative to the previous reference line will be displayed. To facilitate the comparison of the logic of multiple keys, the software has three display channels, select different channels, and then collect data, you can compare the waveform logic of different buttons.
