Colin Chapman / Mbed 2 deprecated MMA7660_x_y_z_LCD

Build upon MMA7660_HelloWorld to pull out x, y, z axes from device and print to LCD on mbed Application Board

Dependencies:   C12832_lcd MMA7660 mbed

Fork of MMA7660_HelloWorld by Erik -

Here reside bits and pieces of coding that is mostly derivative of the work of others. Mostly extensions and other modifications.

The proprioception board project.

Board design images follow.
