Three Essential Tools for Modbus Learning The three essential tools for learning Modbus are ModbusPoll, ModbusSlave, and VSPD, which can facilitate Modbus debugging. ModbusPoll software is mainly used to simulate a Modbus master station or Modbus client. ModbusSlave software is primarily used to simulate a Modbus slave station or Modbus server. VSPD, which stands for … Read more
Some may still be unaware of what Modbus is; in fact, Modbus is widely used in real life, and it is present in almost all industrial electronic device systems. Below, we will describe some common questions about Modbus for beginners. What is Modbus? Modbus is a communication protocol developed by Modicon (now Schneider Electric) in … Read more
Previously, I shared a document-based tutorial on creating an SPI Flash programming algorithm. However, feedback from users indicated that it was not very convenient to port to other microcontrollers. This post is created to facilitate the migration to various platforms. Application scenarios for the SPI Flash programming algorithm: 1. In an IDE environment, such as … Read more
When using TWS true wireless earbuds, with the phone’s Bluetooth turned on, simply opening the earphone case usually allows the earbuds to connect to previously paired devices, eliminating the hassle of re-establishing the connection. This feature is made possible by the application of the Hall sensor, providing users with a smooth connection experience due to … Read more
ET-UARTSWD: An Efficient Tool for Motor and Power Circuit Development In the process of electronic engineering R&D, the quality of debugging tools directly affects project progress and product quality. From the physical image, we can see that ET-UARTSWD, as a debugging tool specifically designed for engineers, is not only made with high-quality materials in hardware … Read more
In Python programming, debugging is a crucial step that helps developers quickly locate and fix issues in their code. SWD (assumed here to represent a specific, powerful debugging library, although in reality, SWD may not directly correspond to any widely known Python library, but for the sake of completeness in this example, we will conceptualize … Read more
If you don’t want to miss my updates, remember to check the public account in the upper right corner and set it as a star, giving me a star in return. Based on the Cortex-M core, the mainstream download interfaces are JTAG and SWD. Differences Between SWD and JTAG Pins: JTAG: TDI: Test Data In. … Read more
There has been a lot of discussion about 100G recently. This year, a new alliance called the SWDM Alliance was established, which utilizes WBMMF fiber, and the WBMMF standard will be released next month. Today, let’s discuss what this is about. The alliance includes many manufacturers, including Commscope (promoting WBMMF), Corning, Panduit, OFS, Prysmian fiber … Read more
Recently, while handling a bunch of data analysis tasks, I was struggling with Excel files every day. I wrote a lot of pandas code and had to remember all those strange function usages. By chance, I discovered the SWD library for Python, and I was amazed after trying it out. Not only can it handle … Read more
Shapefile and File Geodatabase (GDB) are two commonly used spatial data formats in ArcGIS, each with its own characteristics and advantages. The following are the main differences between these two formats: Storage Capacity: Shapefile: The maximum size of a single shapefile is 2GB. File Geodatabase: A single file geodatabase can store up to 1TB of … Read more
