It is well known that industrial production and technological development rely heavily on the automation control provided by PLCs. A PLC can be broadly understood as a centralized relay extension control cabinet. In practical production applications, PLCs significantly reduce the costs of industrial control and enhance centralized management and automatic control of equipment. To master … Read more
Introduction Now we will begin addressing topics related to programming robot controllers. We will design a simple controller to avoid the obstacles (boxes) created in the previous tutorial. This tutorial will introduce you to the basics of robot programming in Webots. By the end of this chapter, you should understand the link between scene tree … Read more
As shown in the figure above, to implement a BLE application, you first need a chip that supports BLE radio frequency, then you need to provide a BLE protocol stack that matches this chip, and finally, you can develop your own application on top of the protocol stack. It can be seen that the BLE … Read more
Respect Function Interfaces and Minimize Internal Modifications C++ Code Statements are divided into: built-in types, names, variables, operators, scalars, strings, preprocessor directives (such as #include), etc.Classes in C++ are defined to organize data structuresThe header files of the standard library are enclosed in angle brackets < >, while non-standard library header files are enclosed in … Read more
Methods for Python to Call C/C++ Programs Recently, while debugging, I encountered a situation where Python was running very slowly, so I researched methods to embed C++ programs in Python. I am documenting this for future reference. Generally, calling C/C++ programs from Python can be divided into three steps: 1. Write the C/C++ implementation program. … Read more
STM32CubeMonitor not only provides variable monitoring capabilities but also offers a rich set of components to build various styles of graphical interfaces, along with numerous free third-party components for functional expansion. Additionally, STM32CubeMonitor supports remote monitoring functionality. STM32CubeMonitor is a variable monitoring and visualization tool that connects to the target MCU via the ST-LINK’s SWD … Read more
1.The multimeter is divided into analog and digital multimeters. As shown in the figure below, the left image is an analog multimeter, and the right image is a digital multimeter. 2.The function of the multimeter is to measure AC voltage, DC voltage, DC current, resistance, and other multifunctional measurements. 3.Pre-use checks for the multimeter. (1) … Read more
Microcontroller development engineers and electronics enthusiasts deal with various digital circuits daily. In addition to using multimeters and oscilloscopes for circuit debugging, a logic analyzer is also essential. A logic analyzer is an instrument that collects and displays digital signals from a test device using a clock, primarily for timing analysis. Unlike oscilloscopes, a logic … Read more
