I2C Communication on Raspberry Pi using JAVA

This project is about connecting MCP23017 16-bit input/output port expander IC with Raspberry Pi by using I2C interface. In order to interact with the IC here, we have used Pi4J and JAVA.

MCP23017 Features:

• 16-bit input/output port expander with interrupt output

• Cascadable for up to 8 devices on one bus

• 25mA sink/source capability per I/O

• Supports 100kHz, 400kHz and 1.7MHz I2C™ Compatible modes
