RS-232, RS-422, and RS-485 are serial data interface standards; communication issues are like traffic issues, with various situations such as high-speed, low-speed, congestion, interruptions, etc. If we compare serial communication to traffic, UART to a station, then a frame of data is like a car. Cars on the road must obey traffic rules. In the … Read more
BFH click the blue text to follow us↑↑↑↑ RS-232, RS-422 and RS-485 are all serial data interface standards. RS-232 is the most widely used serial interface in PC communication. RS-232 is defined as a single-ended standard that increases communication distance in low-speed serial communication. RS-232 uses an unbalanced transmission method, known as single-ended communication, while … Read more

Why Understand the SWD Debug Interface? Debugging is the most critical part of microcontroller development. Early JTAG interfaces required 4-5 wires, occupying too many pins. In contrast, the SWD (Serial Wire Debug) interface only requires 2 essential signal lines, saving PCB space while providing better debugging speed and stability. Currently, almost all ARM Cortex series … Read more
▲Click the card above to follow for more information▲ 1IIC IIC (Inter-Integrated Circuit) bus is a two-wire serial bus developed by PHILIPS for connecting microcontrollers and their peripheral devices. The I2C bus transmits information between the bus and devices using two lines (SDA and SCL), allowing for serial communication between microcontrollers and external devices, or … Read more
Background In the previous section on hardware security, we used a programmer and UART debugging pins to extract the firmware from the Tenda AC6 router, mastering how to obtain firmware through the UART interface and gain terminal access for debugging analysis. Besides the commonly seen UART interface, we often encounter JTAG interfaces on PCB boards, … Read more
Definition of LIN Bus LIN (Local Interconnect Network) is a low-cost serial communication network designed for distributed electronic systems in automobiles. The main function of LIN is to provide auxiliary functionality for CAN bus networks, used in places like body electronic components (such as windows, mirrors, headlights, wipers, etc.). It is suitable for applications that … Read more
