Laser pointer failure restart the laser pointer
During lectures and lectures, I had to use the mouse to turn over the slides and always felt my hands were in a hurry. With a page-turning pen, these problems are solved. However, some problems will inevitably be encountered when using the pen, such as the pen can not turn the page, the restar Green laser pointer keys are confused, and the receiver can not be recognized. What should I do if the flip pen doesn't flip? The failure of the laser pointer to turn pages may be caused by the failure of the driver installation or the poor contact between the receiver and the computer. What should I do if the flip pen light doesn't work?

Please confirm the operating system version of your computer. It may be too old to use. Or some computers originally installed a simplified version of the system (that is, not installed with the usual configuration driver package), some operating systems have not been cleaned for a long time, and the system itself is unstable or has a virus, which can also cause drivers to fail to install properly. In addition, some anti-virus software will prevent the automatic driver installation and prompt you to manually confirm the installation. Solution: Reinstall the laser pointer, replace the computer, and kill the virus completely. If an anti-virus software message is displayed, confirm the installation. The wirelessly emitting laser pointer produces a steady and reliable laser beam, and has five function buttons that send different control messages. According to the design requirements, the laser head is divided into key coding module and wireless transmitting module. The design block diagram is shown in Figure 3. PT2262/PT2272 codec chip is used in this paper, among which PT2262 is the encoding chip. PT2272 is a decoding chip. Based on the working mode of PT2262, a 6-button coding circuit scheme is designed, as shown in Figure 4. K0 to K5 represent six buttons, corresponding to data bits D0 to D5 respectively.
