programming must use the GNU C Kernel programming lacks a memory protection mechanism like user spaceThe memory in the kernel is not paged. Difficult to perform floating-point arithmetic during kernel programming The kernel gives each process only a small fixed-length stack Because the kernel supports asynchronous interrupts, preemption, and SMP, you must always be aware of synchronization and concurrencySMP: Symmetric multi-processing system.Common ways to solve competition: sp

A: The point of time should not be the most important, the most important is the user feedback.The 13th Chapter Software testProblem: There are

Multithreading allows programmers to write efficient programs that maximize CPU utilization3. Two ways to create a thread:① declares a subclass that inherits the thread class and implements the run () method of the Thread class② declares a class that implements the Runnable interface, and then im

First, preface:In the above, the author systematically expounds the two driving modes of 1602, and simply mentions the Liquidcrystal Library of Arduino. In this article, the following two questions are explored in more depth: how can I minimize the 1602-to-Arduino port footprint? How should the Liquidcrystal library learn? Under the Arduino LCD1602 Comprehensive

The article once introduced how to use the RF module to implement wireless control over Arduino. Its principle is very similar to that of remote control, which can implement RF wireless remote control with four buttons. HoweverThis solution is not suitable for data transmission scenarios. For example, you need to transmit the value of the light sensor collected by Arduino to the PC end wirelessly. Technical

Arduino is a convenient, flexible and easy-to-access open source electronic prototyping platform. Includes hardware (various models of Arduino board) and software (Arduino IDE). Smaller than raspberry (Raspberry Pi), but still powerful. It is built on the open source simple I/O interface version and has a processing/wiring development environment that uses Java-l

Just translated the box2d2.3.0 version of the English user's guide, although the original text only 70 pages, not the kind of hundreds of pages of "magnum opus", but still feel the harvest quite abundant. Here also share some of my personal summary of some of the skills and experience. I think that before translating the original textbook, the translator should be more to understand the technical details of the te
