Follow+Star Public Account, don’t miss wonderful content Source | AI Electronics Today I will share with you some features of UART in STM32, mainly targeting newer series of STM32 (such as: STM32H7, G0, G4, etc.), which allows changes to the Rx and Tx pins, level inversion, high-low order, and introduces timeout, etc. Embedded Column 1 … Read more
1. UART: The Art of Asynchronous Communication As Qiu Qianzhang from “The Legend of the Condor Heroes” said, UART is like my lightness kung fu, gliding over the water. If you want to cross the river (communicate), you need to set up markers in advance, and your steps should be fixed according to the distance … Read more
Today, I will share with you the hardware UART peripheral debugging output mechanism under IAR. In the embedded world, outputting print information is a very common auxiliary debugging method. With the help of print information, we can easily locate and analyze program issues. There are many ways to implement print information output in embedded application … Read more
In the previous article on dynamic library encapsulation examples, a CH347 high-speed USB to UART, SPI, I2C, JTAG bridging module was used, which is now open source 👉 GitHub Repository[1]. Introduction CH347 USB High Speed Bridge is a debugging tool designed based on the CH347[2] chip, supporting high-speed USB, allowing USB to UART, USB to … Read more
Click the card above to follow for more information 1. Why Do We Prefer Serial Communication? When working on microcontroller products, the most commonly used method is serial communication. For any microcontroller peripherals, those with serial port functionality are prioritized, such as Bluetooth modules, WIFI modules, 4G modules, electric meters, and displays. Why do we … Read more

Introduction I2C bus is a two-wire, bidirectional serial bus, particularly suitable for communication between ICs on or between boards. To meet system safety specifications, avoid noise signal interference during communication, and prevent damage to sensitive components, it is necessary to incorporate I2C isolator devices into the system. Today, I would like to recommend a domestic … Read more
Today, let’s talk about the topic of microcontroller communication protocols. When microcontrollers interact with peripherals, there needs to be a common language, right? That’s what communication protocols are for! We will focus on three common protocols: UART, SPI, and I2C, and see how they allow devices to communicate with each other. UART: The Simplest Serial … Read more
