An Arduino driver library for the PCF8574 / PCF8574A / PCA8574 family of 8-bit parallel ICs you can interface over I2C.

This library version is deprecated. See v2.0 at I2CParallel2.

This requires only the Arduino Wire library.

I build this with my Arduino makefile.

• Clone the makefile project such that arduino-makefile/ is a sibling of this project directory.
• Create ~/arduino_mk.conf from the template in that directory and customize it to your board and local environment. See other one-time setup instructions in that project's README.md and/or the comment header of arduino.mk.
• You also need to compile Wire for your architecture by running arduino-makefile/install-wire.sh.
• Build this library with make install

• Include I2CParallel.h in your sketch source file.
• Add libs := Wire i2cparallel to your arduino.mk-driven Makefile.
