  First, introduce my installation environment: Windows 7 + wmware workstation 6.5 Then install it. The detailed installation process is mostly online. Here is a brief introduction: (1) Generally, after the virtual machine is installed, the

Some time ago, a simple graphics library was encapsulated in Linux, and the source code of MiniGUI 1.33 was used for reference. After that, I found that programming was very tedious and missed the years of dragging the mouse in windows. Looking at

When multi-thread mutex synchronization is solved, the following problems often occur: 1. How many mutex and semaphore are required in a given question? What is the rule?2. What are the requirements and rules for locking and waiting for semaphores

Serial ProgrammingHardware query methods: query methods, interrupt methods, and DMA methods. Many serial ports use interrupt methods. This method is generally effective for the CPU. UART operations mainly include the following parts:Data

During the loading of modules on the board these two days, I encountered various problems, which were similar to the problems I encountered when loading the module for the first time. Therefore, I recorded the problems in my blog for reference only.

Because the arm-linux-gcc3.4.5 is used, the version is too low, some configurations of the new version of the kernel is not compatible, the old compiler may be using oabi, and when the kernel is configured with the use of Eabi, therefore,

This article uses a simple example to illustrate how to create and use dynamic link libraries in Linux. What is confusing is the path of library files during the compilation of links and the path of library files during the runtime. 1. Create a

Summary: 1. You can save some frequently opened program windows for the next time; 2. You can add a process group to the background for debugging. Original article: Linux tips: use screen to manage your remote sessions

In Linux, once fork has a sub-process, the sub-process will inherit the descriptor of the main process, which brings many problems for developers, such as when I use socket, once I bind a port, and then fork, if the child process from fork does not
