1. Basic concepts of signals: 1. Signal mechanism When process A sends a signal to process B, once process B receives the signal, it will stop the executing process and process the signal. After processing the signal, it will continue to return to execute the previous process. It can be seen that the priority of […]

WebServer parsing timer Timer class (1)
Premise:This WebServer version is not the one on Niuke.com, this version is https://github.com/linyacool/WebServer.git, using the Reactor model At the same time, this is my personal understanding and personal analysis when I was studying, so my analysis may be wrong, and I welcome corrections and exchanges. The main function of the Timer class 1.TimerNode uses the […]

Peripheral advanced timer complementary output with dead zone control experiment
Introduction to complementary output with dead zone control, H bridge, channel introduction In this section, we will learn to use the complementary output with dead zone control function of the advanced timer. Friends who are new to this knowledge may ask: What is complementary output? And with dead zone control? What? Let me tell you […]
PSP – Protein Complex AlphaFold2 Multimer MSA Pairing Logic and Optimization
Welcome to follow my CSDN: https://spike.blog.csdn.net/ URL of this article: https://spike.blog.csdn.net/article/details/134144591 In protein complex structure prediction, when the sequence is a heterologous multi-chain, whether it is AB or AABB, MSA pairing is required, that is, MSA Pairing. During the search process of MSA, the search is performed according to the single chain dimension, merged through […]
FreeRTOS software timer
The software timer is an optional feature of FreeRTOS, implemented based on the system clock beat. Its implementation does not require the use of any hardware timer resources and is not limited in quantity, only system resource permissions are required. Software timers allow specified functions to be executed after the set time has elapsed. This […]
