A collection of uniform, Doxygen-documented C++ classes providing interfaces to a wide range of I2C peripheral devices such as accelerometers, gyroscopes, magnetometers, pressure sensors, ADCs, real-time clocks, and OLED drivers, targeting Arduino/AVR and other C++-based microcontrollers. Each device class builds on a generic I2Cdev abstraction that handles bit- and byte-level I2C communication, making the drivers easy to port across platforms like Arduino, PIC, MSP430, or bit-banged GPIO.

Use cases

• read accelerometer and gyroscope data from an MPU-6050 in an Arduino sketch
• C++ driver library for talking to I2C sensors on a microcontroller
• read magnetometer or barometric pressure sensor data over I2C
• interface an ADS1115 ADC or I/O expander with an AVR microcontroller
• drive an SSD1308 OLED display from an embedded project
• abstract low-level I2C register reads and writes across multiple sensor devices
• connect multiple IMUs or I2C devices using several Wire buses without mux chips

When to choose

• You use Arduino, AVR, or another C++-capable MCU and need ready-made, well-documented drivers for supported I2C sensors and peripherals.
• You want complete register-level coverage of a supported device plus example sketches and online HTML documentation.
• You need a lightweight, statically-used core class to manage multiple I2C devices or multiple I2C transceivers in one project.

When to avoid

• Your specific device is not in the supported device list and you would rather write a small bespoke driver.
• You need a pure C, non-object-oriented interface; the procedural version is still under development.
• You expect standard IDE or package-manager library installation; the monorepo layout requires manually copying folders or creating symlinks.
• You target a platform with no C++ compiler or no ported I2Cdev communication backend.
