Python MCP230XX I2C IO Expander Tools
A couple of basic tools I knocked up while playing with the MCP23017 on my Raspberry Pi. More info on my blog here: http://nathan.chantrell.net
mcp23017.py
A simple command line tool for setting outputs as high or low.
Usage: mcp23017.py -b
eg. to set GPA1 high: mcp23017.py -b a -o 1 -s high
Response: Output GPA1 changed to high
Requires python-smbus
mcp23017.wsgi
A web interface using Python and modwsgi. Can be controlled through the built in web form or via GET requests with optional JSON like responses.
eg. to set output GPA1 high: http://rpi/mcp23017.wsgi?bank=a&output=1&state=high&mode=json
Response: {"GPA1":"HIGH"}
Requires python-smbus and apache with mod-wsgi. Note that you will need to make sure your web server has permissions for the i2c bus, eg. /dev/i2c-0
To do: Extend to cater for input as well as output and report on the current state of the outputs.

As an avid user of the Python-MCP230XX library, I highly recommend it for anyone working with MCP230xx GPIO expanders. This library, authored by nathanchantrell, provides a straightforward and efficient way to control these expanders using Python. The documentation is clear, and the code is well-maintained, making it an excellent resource for both beginners and experienced developers. Find it on GitHub: https://github.com/nathanchantrell/Python-MCP230XX.
