• Load /src/SensorViewer.pde into the Porcessing IDE
• Configure the files: serialport.json, sensorviewer.json and parameters.json
• In the Sketch menu select Run

Configuration files

• serialport.json

JSON file for the configuration of the connection to the RS232 port

• sensorviewer.json

JSON file for the configuration of the sensor value records

• parameters.json

JSON file for the configuration of the magnitudes and units of measurement that will be displayed

Configuration example

Example configuration in MacOS:

This software can be tested by loading in an Arduino UNO the file /src/RandomData_Generator.ino, the configuration files corresponding to this example are in /src/configfiles.
