In the previous issue, we discussed how PLCs “read” analog signals (such as temperature and pressure). In this issue, we will talk about how PLCs “write” analog signals—such as controlling the speed of an inverter or adjusting the opening of a valve. Many beginners find this part complex, but as long as you understand “how … Read more
When we use devices such as PLCs, sensors, and servo motors, we often encounter some technical terms like AI, AO, DI, and DO, which many people find complex and difficult to understand. In fact, they are not as hard to grasp as we might think. Today, we will clarify what these terms mean to help … Read more
New Features of cout In C++, cout is a powerful output tool that can intelligently handle different types of data and automatically perform appropriate conversions. This intelligent behavior stems from C++’s object-oriented features and operator overloading. Basic Usage of cout Printing Strings #include <iostream> using namespace std; int main() { cout << "Hello, World!"; // … Read more
1.2 Introduction to Input and Output The previous section explained “output” (<span><span>std::cout</span></span>), this section supplements “input” (<span><span>std::cin</span></span>), and introduces “how to achieve interaction between the program and the user through input and output”—the core is to master the basic usage of<span><span>std::cin</span></span> and <span><span>std::cout</span></span>, as well as the simplification of the <span><span>std</span></span> namespace. 1.2.1 Standard Input: … Read more

MitsubishiQSeriesPLCAnalog Output Module for Controlling Inverters Implementing0-50Hz precise speed control solutions Application Overview In industrial automation control systems, using the MitsubishiQSeriesPLCanalog output module to control inverters is a common application scenario. By controlling the inverter output frequency with analog signals (0-10V or 4-20mA), stepless speed regulation of motors can be achieved to meet various process … Read more
Abstract This article delves into the hardware architecture and design philosophy of Google’s Tensor Processing Unit (TPU). It covers the components of a single TPU chip (including matrix multiplication units, vector processing units, and memory hierarchy) to the interconnection topology of multiple chips (such as 2D/3D toroidal connections and optical switching technology). The article discusses … Read more
This article mainly introduces methods for outputting logs in embedded development. The most common method is to output UART logs through the serial port. This method is simple to implement, and most embedded chips have serial port functionality. Related articles: Learning STM32 Microcontroller, Serial Port is Inevitable. However, such a simple function can sometimes be … Read more
We designed a subroutine for processing analog outputs, which can convert engineering values into analog output values, and includes output limits, gain adjustments, and alarm functions.Features: Converts engineering values (real numbers) into integers ranging from 0 to 27648 for analog output. Allows setting of gain and offset to adjust output characteristics. Allows setting of upper … Read more
