Windows Driver Development Foundation, reprint marked Source: http://blog.csdn.net/ikerpeng/article/details/38793995Let's talk about how to compile the driver after it's developed. Generally there are several ways to do this:1. Create makefile file, compile and link with NMAKE tool;2. Build makefile,sources, dirs file, compile with build tool.3. Compile the link with the integrated development environment.I

Windows cannot verify the digital signature of the driver required for this device. A software or hardware has recently changed and may have a signed or damaged file installed, or the file may be an unsolicited malicious software. (Code 52)Recently replaced a new motherboard, upgraded WINDOWS10 RS2 (14955)The good news is that Windows 10 is now like an apple, capable of supporting the coreaudio of those sound cards, and is free-drive.The bad news is t

I. Overview Speaking of writing I2C drivers in Linux, there are currently two main methods: one is to treat I2C devices as a common character device, the other is to use the Linux I2C driver architecture. The two drivers are compared below. The advantages of the first method (corresponding to the disadvantages of the second method) include:● The idea is straightforward and you don't need to take the time to understand the complex I2C subsystem operati
