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。

All the devices with features are mentioned below. The NCA9595 differs from competing GPIO expanders by incorporating a register configurable internal pull-up resistor. This element removes the ...

Nexperia has released a new portfolio of 16-channel I2C GPIO expanders created to improve flexibility and reuse in electronic systems. The portfolio offers an elegant solution for requiring extra I/Os ...

Undeterred, he created an i2c expansion board using an MCP23017 I/O port expander, and with a novel card-edge designed to mate with the screw terminals, solving both problems at once.
