In the past two days, according to the method of learning from the Internet, an infrared computer remote controller was used. It was very successful, and it was quite cool. Can imitate the mouse and keyboard, achieve shut down and restart regularly, but also control some common multimedia software, such as thousands of listen, storm video and so on. Because its sending end is an ordinary TV remote control, the decoding of the receiving end is completed by the computer software (IRCtrl 2.4 download address below), so only need to be an infrared receiver that can connect with the serial port of the computer. Only a few electronic components can be set up for this receiver, so it is not complicated to do it. If you are interested in referencing the following circuit diagrams, you can believe that it can be done quickly. Do not talk about nonsense, see finished product map: The state of use, very small, and serial port extension connected to the chassis can be. A few close-ups On the back... oh... wiring is a bit messy Remote control, any TV remote control can be identified The following is the interface to receive decoding software, which is equivalent to the driver of this remote control. Download address see the end of the article. This software is very selfless, although it is a professional computer remote control worn, but it has a strong learning ability to be able to read and identify almost all TV and DVD, VCD remote control infrared encoding format. When you use it, you can define the corresponding function of each key. The specific method can refer to its use help. The following is the hardware circuit diagram. The 0038 in the upper left corner is an all-in-one integrated infrared receiver. There are several models such as HS0038 and SM0038, which can be used universally. Almost all of them sell electronic components. It can complete the acceptance and amplification of infrared signals. Receive instructions and power indications are optional. I have omitted the power indicator. The rightmost 2 7 4 5 are connected to the 2 7 4 5 pins of the 9-hole serial port. Coupled with several diode transistor resistors and capacitors became! The following is the physical map and pin definition of 0038
