Inlinino - Instrumentino v1 Fork

A simple data logger

Purpose of the project

Inlinino is design to log data from sensors (with analog or serial interface) continuisly during days. It is written in Python 2.7 and is a fork from Instrumentino. The user interface is very simple and allow visualization of the data in real-time. To date, the software can log data from the analog and digital ports of an Arduino and from WETLabs ECO series sensors.

Instrumentino is an open-source modular graphical user interface framework for controlling Arduino based experimental instruments and any other instrument for which python API exist or can be developped.

Differences between Instrumentino v1 and Inlinino

The main difference between Instrumentino and Inlinino resids in the fact that Instrumentino is build to control instruments during short period of time (less than a day) whereas inlinino can only read data from those instruments but during an extensive period of time. In fact, inlinino use a ring buffer to plot and log data whereas instrumentino use a classic list that keeps expending as the program run. Inlinino is creating hourly log files and will create a new log file at midnight when switching day. A big part of instrumentino's code was removed in order to make the software lighter but it can easily be added back.

Content of the application

Two separate programs:

• instrumentino: run on a PC/Mac and provides the graphical user interface for logging and visualizing the data
• controlino: run on the Arduino controller itself and communicates with instrumentino

The other folder contains:

• configurations: python scripts to start inlinino with a given configuration

Starting Inlinino

After following the installation steps described in INSTALL.md, Inlinino can be started for a specific configuration. On OSX:

cd configurations/test/
nice -20 pythonw __main__.py

Note: use nice to set the application priority by (-20 is the highest), use pythonw instead of python to show the GUI of the application. On Windows:

• Navigate to configurations\test\ or another configuration\Tara\
• Launch the applicaion by double clicking __main__.py or __main__.pyw Note: by default *.py are started with python.exe and *.pyw are started by pythonw.exe. python.exe will start with a terminal window and will show any error or print statement ouput by the application whereas pythonw.exe will show only the GUI of the application and no error is shown.
