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

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
Recently, I saw some netizens discussing whether ‘CAN is more difficult than UART’ in a technical group. Some netizens said CAN is very simple, while others said CAN is very difficult. In fact, whether it is difficult or not mainly depends on your perspective. Some netizens may have a good foundation and have studied CAN, … Read more
Overview:The I2C communication interface is the most commonly used MCU peripheral in our daily applications. Initially, before the MCU had hardware I2C, I2C communication was achieved by simulating the I2C timing through GPIO ports. Later, with the introduction of hardware I2C peripheral interfaces in MCUs, the use of hardware I2C became commonplace. More importantly, it … Read more
Bus applications are very widespread in the field of computers. (1) The method of transmitting information via the system bus can be divided into the following three types: 1. Data Bus 2. Address Bus 3. Control Bus (2) According to the usage range of the bus, it can be further divided into many types: such … Read more

I2C Introduction 1.1 I2C History I2C: Inter-Integrated Circuit, an integrated circuit bus. I2C is a simple, bidirectional two-wire synchronous serial bus designed by Philips in 1982 … Read more
Click the blue text above to follow us 1. What is I2C? I2C, short for Inter Integrated Circuit, is a two-wire serial bus developed by Philips for communication between SOCs and peripherals. It requires only two wires for communication, operating in a master-slave mode where the master can read and write data, while the slave … Read more
Satellite communication typically occurs in one of ten frequency bands. The specific frequencies available within each band depend on applicable licensing regulations. While certain portions of the bands are allocated globally for satellite use, others may be exempt from licensing and can be used in specific circumstances. The International Telecommunication Union (ITU) is responsible for … Read more

ARM9, ARM11? 3. Cortex-M is newer than ARM9, why can’t it run Linux? Many people may have similar questions, so let’s discuss Cortex-M, ARM, and Linux. ARM … Read more
Programming is a term that tells computers how to work. Through programming, we can easily manipulate any technology. Just like everyone has their own language or specific dialect in certain regions, computers or advanced technologies also have specific languages, and its name is “programming.” Those who engage in programming are called programmers. However, merely learning … Read more
