The EEZ Studio is an open source cross-platform (developed in Electron) modular visual tool aimed to address various programming and management tasks for EEZ H24005 programmable power supply and other test and measurement instruments that support SCPI.

 

Two main driving forces or ideas behind development of EEZ Studio were completely practical: firstly it's an attempt to speed up development of HMI based on TFT color touch-screen display and secondly, experimenting on daily basis with electronics that include usage of above mentioned power supply and also DSO (both equipped with SCPI) requires lots of interaction and generates huge piles of screenshoots (oscillograms) that became a real challenge to manage as project or experimentation went on.

 

Making HMI that is in the same time functional, flexible (i.e. easily customizable) and foolproof is still an exhaustively complex task. Many commercial HMI solutions exists that promising a lot, but at the end if only one feature is needed that is currently not supported (and without plan to be supported in the foreseeable future) that could jeopardize a whole project. Therefore we decide to follow our own track trying to push to the limit initially selected entry-level display and MCU (i.e. no GPU, FPU, DMA, frame buffer, etc.) and make it available as open source.

 

Today, more sophisticated T&M (test and measurement) equipment are widely available, and one of the reason why we can labeled it sophisticated is that they are digital and thanks to that should by default offer simple data collection for further processing and archiving. But, what we experienced from “out of the box” offering wasn’t promising: at the end the most practical (i.e. time and human energy/awareness efficient) was to simply plug memory stick into USB host port and make “screen copy” (stored as bitmap!). Anything beyond that asked for “rocket science” and extra money (for “full featured” software, etc.).

Related to work in the lab, we realized that while experimenting, if collected screenshots are not instantly labeled and at least moved into folder with proper (suggestively enough) name, they easily became outdated and enigmatic. Therefore to make collected measurements usable for further usage more organized approach is needed with features like: taking notes, attaching comments to new collected data, easily accessed (searchable and filtered) history of all previously taken steps, etc.

 

Keeping in mind what is said previously the EEZ Studio is conceived to bring over the time the following functionality and features (the list is a not final one and will be timely updated):

General

  • Cross-platform run-time (Linux, Windows, Mac OS X)
  • Modular design based on plug-ins that can be added/removed depends of scope of the work
  • Open source, flexible licensing (e.g. free for personal use and education, support fee based for businesses)

Development

  • Component title: EEZ Studio Project Editor or ESP
  • Visual editor for designing TFT display screen decorations and defining user interaction (HMI)
  • Generating C++ code for HMI functionality that can be directly included in Arduino IDE and upload into the 32-bit Due board
  • Instrument definition file (IDF) builder with context sensitive SCPI commands help (based on Keysight’s Offline Command Expert command set XML structure) suitable for EEZ Studio Workbench (ESW) and Keysight Command Expert
  • SCPI command help generator based on bookmarked HTML generated directly from .odt file using EEZ WebPublish extension for OpenOffice/LibreOffice.

Management

  • Component title: EEZ Studio Workbench or ESW
  • Dynamic environment where multiple instruments and other “widgets” can be placed and easily accessed
  • Session oriented communication with each SCPI instrument
  • Support for serial (via USB) and TCP/IP communication
  • Direct import of ESP generated IDFs and Keysight’s Offline Command Expert command sets
  • History of all activities with search/content filtering
  • Quick navigation via calendar ("heatmap") or sessions list view
  • Shortcuts (hotkeys and buttons) that can be user defined or come predefined from imported IDF. The shortcut can contain single or sequence of SCPI commands or Javascript code
  • Javascript code for task automation (e.g. logfile, or programming list upload/download, etc.)
  • SCPI commands context sensitive help with search
  • File upload (instrument to PC) with image preview (e.g. screenshots)
  • File download (PC to instrument) automation for transferring instrument profiles
  • Initial support for serial (via USB) and TCP/IP communication
  • Simple arbitrary waveform editor (envelope and table mode)
  • Displaying measurement data as graphs

 

Scheduled for future milestones:

 

  • Support for other connections (i.e. VXI-11, USBTMC, IVI) using 3rd party open source
  • Instrument extensions for popular instruments from other vendors
  • Print and PDF export
  • (External) data logger
  • Protocol analyzer using 3rd party open source
  • Import/export of all working data (i.e. measurements, session history, shortcuts, settings, etc.) for archiving purposes or easier integration with e.g. ELNs
