Mitutoyo SPC Data Reader for Arduino

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_OUTPUT to output data in hexadecimal form.
• HUMAN_READABLE_OUTPUT to 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.
