Click to follow and never lose your way in learning! In the previous chapters, we thoroughly explored the MODBUS protocol in serial communication, from basics to applications, and it was quite an exhilarating journey. However, as times progress and technology advances, serial communication, while classic, is like a horse-drawn carriage that cannot keep up with … Read more
1. Comparison of Communication Speeds: SPI, I2C, UART SPI > I2C > UART 1. Synchronous communication > Asynchronous communication; 2. In synchronous communication, a clock line must connect both ends of the transmission; 3. All are serial communication methods, while parallel communication is used for internal storage communication, such as flash; 4. The suitable transmission … Read more

MicroPython, a name that sounds extraordinary, is the “mini” version of Python, … Read more
CANopen serves as a “common language” among industrial devices, enabling seamless “communication” between devices from different manufacturers. The S7-200 SMART, equipped with a CANopen module, acts like a proficient “translator” of this language, effortlessly commanding and coordinating various intelligent devices. This technology simplifies complex automation systems, allowing what once required intricate wiring to be connected … Read more
Implementing the SPI (Serial Peripheral Interface) driver on the STM32 microcontroller for communication with sensors. The content includes SPI initialization, data transmission, error handling, debugging techniques, and the use of logic analyzers. The code is based on the STM32Cube HAL library, suitable for the STM32F4 series (such as STM32F407), and uses a generic sensor (like … Read more
Why is I2C so important? In modern electronic devices, communication between chips is ubiquitous. For example, your device has dozens of sensors and chips that need to “talk” to each other—the accelerometer needs to inform the processor of the device’s motion state, the touchscreen needs to relay user click information, and the camera needs to … Read more
In today’s low-end digital communication applications, we frequently encounter IIC (Inter-Integrated Circuit) and SPI (Serial Peripheral Interface). The reason is that these two communication protocols are very suitable for short-distance, low-speed communication between chips. Philips (for IIC) and Motorola (for SPI) developed these two standard communication protocols based on different backgrounds and market needs. IIC … Read more
C++ IoT Development: Communication Between Sensors and Devices In the world of the Internet of Things (IoT), communication between sensors and devices is crucial. As a full-stack programmer, this article will detail how to use C++ for IoT development, particularly focusing on establishing effective communication between sensors and devices. 1. Overview In this tutorial, we … Read more
Click the blue text to follow us Currently, large models are quite popular. When we initiate requests on web pages or mobile clients, the communication protocol used is SSE (Server-Sent Events). HTTP and WebSocket are two communication protocols similar to SSE. These three different network communication protocols are suitable for different scenarios, and here we … Read more
In electronic engineering, embedded development, and IoT projects, serial communication is a common method for data transmission. To facilitate developers in debugging serial devices, an efficient, user-friendly, and feature-rich serial debugging tool is essential. Today, we introduce a completely free and open-source serial debugging tool—UartAssist.Download link at the end of the article! 01 ————— Software … Read more
