At the beginning, led projectors were listed because of low lumen bottlenecks, which did not make people think of their great practicality. Therefore, they were once banned ". Because the brightness of listed machines is between dozens of lumens, the projection screen effect is very dark. Even if the light is turned off, the screen effect is still normal. As a result, it is impossible to meet the needs of most people and can only be used as toys. With

in the 64bits system MATLAB 64-bit software does not have the LED control ActiveX control, the LED ActiveX control controls are located in the Gauges Blockset module, and gauges Bloc Kset module can only be installed in the version of Matlab 32-bit (not necessarily need to install in window 32-bit, I test environment is win10 64bit), in WIN10 64-bit environment installed by default is Matlab 64-bit, So the

LED Driver Implementation Principle : Although the Liunx drive directly with the hardware, but not the Linux driver directly to the hardware in the hardware of the memory data, but with the native I/O memory interaction, so-called i/ o Memory is a mapping of hardware in host memory that is connected to the host through various interfaces. The Liunx kernel provides multiple functions that interact with I/O memory, and each hardware that connects Liunx

This chapter completes a real Linux Drive. The Linux driver is used to control 4 LED lights on the development version . that is, by sending data to the Linux driver, you can control The switch of the LED light. In order to address this driver conveniently, this book and later chapters refer to it as the LED driver. The realization principle of

27. Light the LED operationLEDs can be used as a tool for my debug program: In embedded system software, such as bootloader and kernel, in the early stages of development, because the serial port and other hardware has not been initialized, so debugging means is quite limited, this time can use led as a debugging means.OK6410 schematic diagram of the LED:From know, to let

In accordance with the normal application of the topology of computers, routers, cats connected, if the corresponding router LED is not bright, this problem may be connected with the network cable, fault, port failure and other reasons, this article provides detailed troubleshooting ideas. The WAN port LEDs are not lit 1, check whether the WAN port wiring, check and WAN port connection of the cat is power (network cable households without troublesho

One: Led driver writingTo write LED drivers, the first knowledge of the Development Board structure, the Development Board is divided into the core board and the backplane; the first step in writing a driver is to look at the Development Board, find the position of the LED light on the Development Board and the corresponding name; The first step is to view the co
