When we study microcontrollers, the first thing we may encounter is lighting up (GPIO), and then comes the serial port (UART). The serial port is a commonly used communication interface and is a necessary knowledge to master in embedded systems. However, I have found that many friends only know how to use the serial port … Read more
Welcome FPGA engineers to join the official WeChat technical group. UART (Universal Asynchronous Receiver-Transmitter) Transceiver Module Design – 01 Introduction to UART Protocol UART, as a type of asynchronous serial communication protocol, operates by transmitting data one bit at a time. Each bit has the following meanings: Idle Bit: When there is no data transmission, … 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, and take down a star for me. This analysis question still comes from Huawei’s hardware position written test questions. This time we analyze three multiple-choice questions, involving knowledge points: UART … Read more
▲Click the card above to follow and learn more▲ Communication issues, like traffic problems, can vary in speed, congestion, and interruptions. If we compare serial communication to traffic, UART can be likened to a station, and a frame of data is akin to a car. Cars on the road must obey traffic rules. In the … Read more

Some said CAN is easy, while others said it is difficult. In fact, whether it is difficult or not mainly depends on your … Read more
When performing IoT analysis, accessing the device’s UART interface for debugging is a common operation. UART generally includes at least four pins: the common ground pin GND, the power pin VCC, the output pin TXD, and the receive pin RXD. We need to use three of these pins: TXD, RXD, and GND. If you find … Read more
Click the blue text to enter ADI, and then click the upper right corner to mark it as a favorite! UART, or Universal Asynchronous Receiver/Transmitter, is one of the most commonly used communication protocols between devices. This article will explain the standard steps that should be followed when using UART as a hardware communication protocol. … Read more
SPI (Serial Peripheral Interface) SPI is a high-speed, full-duplex, synchronous, serial communication bus with a 3-4 wire interface, operating in a master-slave mode, allowing multiple SPI devices to be interconnected. The SPI device that provides the SPI serial clock is the SPI master, while other devices are the SPI slaves. The SPI bus consists of … Read more

The MCU UART (Universal Asynchronous Receiver-Transmitter) achieving sleep wake-up functionality typically involves low power design, interrupt mechanisms, and UART configuration. Below, we … Read more
I2C Communication Protocol Basics 3.1 Introduction to Communication I²C (Inter-Integrated Circuit) is a serial communication bus designed by Philips in the early 1980s. It facilitates communication between motherboards, embedded systems, or mobile phones and peripheral devices. Due to its simplicity, it is widely used for communication between microcontrollers and sensor arrays, displays, IoT devices, EEPROMs, … Read more
