A repository to demonstrate the usage of a i2c muliplexer for using two sensors on the same i2c bus. - Sensirion/arduino-i2c-multiplexer-usage ...

Have you ever found yourself wanting to connect more than one I2C device to a single controller and couldn't because they have identical I2C addresses? There you have it, I2C multiplexer (I2C MUX) ...

例えば、下記は、ArduinoIDEで、開発デバイスをArduino UNO R3など開発デバイスとしたときに出てくるWire (I2C)のサンプルスケッチ (slave_receiver.ino)です。これはArduinoをI2Cのスレーブとして動作させ、マスターからのデータを受信する例です。

ラズパイ側ではi2c_file_slaveを実行し、指定したファイルをArduinoに転送します。 Arduino側では受信したデータを、test.binのファイル名でSDカードに保管します。

In this tutorial we will use I2C communication between two arduino boards and send (0 to 127) values to each other by using potentiometer.

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino … ...
