Use an Arduino Nano to translate Mitutoyo Digitmatic SPC data to USB serial for easy consumption by Node-RED or any other software that accepts USB serial data.
Includes two build-time options set via #define:
HEX_DATA_OUTPUTto output data in hexadecimal form.HUMAN_READABLE_OUTPUTto output a more human-readable form that mimics what is shown on the instrument's built in LCD.
The directory structure here is a
Platform.IO project
but the code in src\main.cpp should be easy to copy & paste into the standard
Arduino IDE.
