This article guide The RS-485 bus is a half-duplex communication bus, so it usually requires an MCU to control the transmit/receive state of the RS-485 transceiver. To save MCU I/O resources, RS-485 automatic transceivers have emerged, but these types of transceivers encounter some application issues to varying degrees. How can these issues be resolved? This … Read more

01 【SPI Concept】 SPI (Serial Peripheral Interface) is a synchronous serial port for communication between microcontroller units (MCUs) and peripheral ICs (such as sensors, ADCs, DACs, driver chips, and external storage devices). The communication rate can range from a few thousand bps to hundreds of Mbps or even higher, depending on the specifications and performance … Read more
Click the blue words Follow us 1. Introduction to CAN Background of the CAN Protocol In the 1980s, the number of electronic control units (ECUs) in automobiles gradually increased, and traditional point-to-point electrical communication methods were becoming inadequate. The point-to-point connections between each electronic control unit and other devices made system wiring complex, costly, and … Read more

Proteus is a single application with many service modules that provide different functions (schematic capture, PCB layout, etc.). The wrapper that allows all various tools to communicate with each … Read more
Build a 100MHz Logic Analyzer with Raspberry Pi Pico Transform a Raspberry Pi Pico (or any RP2040 board) into a simple logic analyzer in just 5 minutes. Introduction A logic analyzer is an electronic instrument that captures and displays multiple signals from digital systems or circuits. It can convert captured data into timing diagrams, protocol … Read more
Abstract There are numerous articles introducing the performance of logic analyzers, but few specifically discuss the measurement probes for logic analyzers. It is important to note that the instrument itself is only part of the measurement system; the choice of measurement probes and their manufacturing processes are also crucial. Many times, we use the most … Read more
