An Arduino library for I²C device operations. This is an abstraction class which can be used for all I²C devices to manage its access in register access level. On addition to the device abstraction, ...

This Arduino Mega/Due sketches use direct port read and bit manipulations to sniff an i2c bus running at up to 100 kHz. The analysis of the i2c communication is displayed on the Serial monitor.

秋月電子で購入したBOSCH社製9軸センサ「BNO055」を実装したセンサーフュージョンモジュール「AE-BNO055-BO」を使用し、「Arduino UNO R4 MINIMA」とI2C通信を行いました。が、動作確認できるまでに少々苦労したので備忘録としてまとめました。 下記が回路構成です。

The I2C (Inter-Integrated Circuit) bus is a synchronous serial communication protocol that allows multiple electronic components (sensors, displays, memories, etc.) to be connected within the same ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

If you’ve ever been laying out a network I2C devices inside a project box or throughout your robot’s body, you’ll probably know that I2C is not without its pitfalls. But for many of those pitfalls, ...
