Digimatic SPC to Arduino

12/2/2011 Update! We are now reading data from the micrometer, and calculating bin numbers for gear sorting and pump builds. We take 3 samples of a gear, and reject the gear if there is too much variation between the samples.

The Digimatic SPC protocol is a communications protocol developed by Mitutoyu, the big guns in Calipers, Micrometers, Dial Indicators, Scales and more. These devices have a data port that allows you to communicate with a microprocessor or microcontroller, for data logging and other measuring applications.
