Kevin O'Connor e26d1a3567 i2ccmds: Pass the i2c address as a 7-bit number (0-127) 
The sam3 i2c code and the linux code use a 7-bit i2c address, while
the avr, lpc176x, and samd21 i2c code uses an 8-bit address with the
least significant bit always zero.  A similar issue occurred in the
host code (sx1509.py and replicape.py use 7-bit addresses while
uc1701.py and mcp4451.py use 8-bit addresses).

Consistently use 7-bit addresses in all the code.  This breaks
compatibility between host and mcu software, so make a change to the
config_i2c command to force users to synchronize software updates.
This also breaks common Smoothieboard configs, so update the mcp4451
code to validate the i2c_address.

README.md

Welcome to the Klipper project!

This project implements a 3d-printer firmware. There are two parts to this firmware - code that runs on a micro-controller and code that runs on a host machine. The host software does the work to build a schedule of events, while the micro-controller software does the work to execute the provided schedule at the specified times.

See the features document to find out why you should use Klipper. To begin using Klipper start by installing it.

There is also developer documentation available.
