[Image] The I2C bus (Inter-Integrated Circuit), also known as IIC or I2C, is a two-wire serial bus developed by PHILIPS for connecting microcontrollers and their peripheral devices. It is a widely adopted bus standard in the field of microelectronics for communication control. It…
UART, SPI, and I2C are very common serial communication methods in embedded development. The underlying communication principles of these protocols are not difficult, but many beginners struggle to learn them. Today, I will share some common underlying data transmission principles of these communication methods. UART Serial Communication UART: Universal Asynchronous Receiver-Transmitter. The UART serial port … Read more

Click the blue text Follow us 1. Introduction to I2C The I2C communication protocol (Inter-Integrated Circuit) was developed by Philips. Due to its fewer pins, simple hardware implementation, and strong scalability, it does not require external transceivers for communication protocols like USART or CAN, and is now widely used for communication between multiple integrated circuits … Read more
Click the aboveblue text to follow us The I2C bus, as a widely used communication protocol in embedded systems, has its stability and reliability directly affecting the overall performance of the system. An I2C deadlock refers to a situation where the bus is stuck and unable to continue communication, usually caused by a slave device … Read more
During the use of I2C, we may observe half-high levels or glitch phenomena. This article attempts to explain the causes of these phenomena and their impact on applications. The main content is as follows: 1. Glitch/Half-High Level Phenomenon 2. Characteristics of Glitches/Half-High Levels 3. Causes of Glitches 4. Is the Existence of Glitches Reasonable? 5. … Read more
