Getting Started with neural networks (serial 1-6)

version of a real nerve cell, but are simulated in an electronic way. The number of artificial neural cells used in an artificial neural network can vary greatly. Some neural networks require only 10 artificial nerve cells, while some neural networks may require the use of thousands of artificial nerve cells. It all depends on what these artificial neural networks are prepared to actually do. Interesting facts.A fellow named Hugo de Garis, who had created and trained a network of 1

Explanation of using do{...} while (0) in embedded programming

Recently looking at ESP32 's IDF, there are some macro definitions that use the Do while (0) code that seems to be useless. Then I looked up the information and found that it was often used in Linux kernel code!Now get this thing sorted out.Why do you encounter a lot in the kernel#define ... There are several reasons for this:1, the empty statement will be compiled when the warning appears, so it is necessary to use the # define FOO do{} while (0)2,

Quick knowledge of the Linkit 7697 Development Board

LinkIt 7697 is a versatile and affordable development Board that can be used to connect to your network or to your devices, while providing both Wi-Fi and Bluetooth online capabilities. The Development Board uses the MediaTek MT7697 chip, which is a little bit less than the ESP32 microcontroller used in other similar wi-fi/bluetooth development boards, but still far superior to Arduino Uno. After adding the board data and installing the USB driver in

Introduction to JSF 2, part 2nd: Templates and composite components

source Facelets implementations, the JSF 2 Expert group also made changes to the underlying Facelets APIs, but retained a back-to compatibility with the tag library. This means that the existing views implemented with open source Facelets should apply to JSF 2.More information about Facelets's many features can be found in these two articles in Rick Hightower, "Facelets is perfect for JSF" and "Advanced Facelets programming." Tip 1: Follow th
