In the previous article, a "group chat system based on TCP design" was written to demonstrate the use of the select function. This article then introduces the remaining poll and epoll functions. And use poll and epoll functions to rewrite the client code to complete port data monitoring
"Live up to the time, the creation of non-stop, this article is participating in 2021 year-end summary essay contest" preface MY junior student.

Not only can help you say while recognizing, export into chapter, when there is a personalized name is not difficult to it. That's the beauty of embedded speech recognition. The selection of embedded speech recognition technology is introduced. Speech recognition, which allows machines to "understand" human speech and identify the content of speech as corresponding text. It can be said that speech recognition is the forefront of human conquest of artificial intelligence, is currently machine translation, natural language understanding, human-computer interaction...
Just like memorizing text when we were young, there are some codes that need to be memorized (a little exaggeration, but at least familiar). The demo of threadX for STM32 is posted here today to familiarize me a little bit.
The purpose is to demonstrate how to use ThreadX in an embedded multithreaded environment. The demo includes initialization, eight threads, a byte pool, a block pool, a queue, a semaphore, a mutex, and an event flag group.
In this section, we are familiar with the three components of servlet, servlet, filter, listener, and the built-in Tomcat of SpringBoot. Springboot does not support JSP (because of embedded Tomcat).
