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. We are still working on getting this working, and I'm posting the info I have in the hope others are helped, and may be able to help us.

Thanks to Grumpy_Mike (Mike Cook) from http://www.thebox.myzen.co.uk we are now getting readings from the Micrometer. Have to play a bit more with the binary output, and stuff the different pieces of the data stream into variables, but we are very close!
ReplyDeleteThanks to GoForSmoke on the Arduino forums for a very useful bit reversal function that really woke this project up!
