Particle IDE library for using a keypad with an I2C I/O expander Pins on Photons are scarce! Don't waste your pins on a keypad when you can connect it over I2C. This library allows makers to integrate a keypad into their project using two simple wires. Currently works with the Adafruit MCP23008 and MCP23017 I2C controllers.

Particle-Keypad-I2C is Evan Simkowitz's adaptation of Sandro Lange's Spark Core port of Alexander Brevig and Mark Stanley's Keyboard Arduino library. The Adafruit_MCP23008 library is Evan Simkowitz's Particle IDE port of Limor Fried/Ladyada's library for Adafruit Industries. The Adafruit_MCP23017 library is Paul Kourany's Particle IDE port of Limor Fried/Ladyada's library for Adafruit Industries.
This library allows for operation of a keypad over I2C. This library is compatible with the following Particle boards: Photon, P1, Electron, Core. Currently the supported I2C chips are the MCP23017 and MCP23008.
I plan to add support for more I2C chips in the future so stay tuned! That said, if anyone wants to help me with that, I would be much obliged! Enjoy and please send pull requests if you add any functionality.
