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

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

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
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
Look at the image below; you probably guessed that today’s protagonist is UART. The serial port we commonly refer to includes both TTL level and RS-232 level, and in embedded systems, the serial port of microcontrollers is usually TTL level. Today’s content is about the frame format of UART, which is quite simple; those who … Read more
