I2C (Inter-Integrated Circuit) is a serial communication protocol used for short-distance communication, typically for data transmission between microcontrollers and various peripheral devices (such as sensors, displays, memory, etc.). Characteristics of the I2C Protocol The I2C protocol has several notable features: Two-wire Communication: The I2C protocol uses only two signal lines: SDA (data line) and SCL … Read more
In today’s booming era of the Internet of Things (IoT), microcontrollers play a crucial role as core control units. Bluetooth technology, with its convenient wireless communication characteristics, has expanded the application space for microcontrollers. The STM32 series microcontrollers are favored by developers for their high performance and low power consumption. 1. Overview of Bluetooth (1) … Read more
The I2C bus is one of the most commonly used communication protocols in embedded systems, serving as a “dedicated highway” between microcontrollers and various sensors and memory devices. Today, let’s discuss how this protocol works and how to use it to read data from temperature and humidity sensors. I2C Protocol Basics The I2C protocol uses … Read more
