Thanks to Andrew Young (yngndrw) we got IEXT for Keysight DSO/MSO Infiniivision 2000 X series ...

I am glad to announce EEZ Flow to you. It allows visual programming like Node-RED, or say LabVIEW if we are talking about T&M solutions. We have been thinking about EEZ Flow (which we didn't even know what it would be called at the time) for more than five years and finally something started happening in that area thanks primarily to NLnet who decided to sponsor its development.
Yesterday, the first milestone (tagged as Pre-release 0.9.8.1) was completed, which brings the first basic elements for creating flowcharts from existing components, editing, copying, deleting, etc. EEZ flow will be able to work with three types of components: Widgets and Actions are already supported and we will add Decorations. The important thing is that it will be possible to import external components as well, so as a first example, a component was created to connect to the Postgres database. This will allow other developers to add their own components.

We continue to work on the EEZ flow and through the next four milestones the idea is to achieve the following:

* Execute flows on a PC (to control various instruments including BB3) and display the corresponding dashboards
* Execute flows directly on BB3 which will mean that the complete existing GUI can be replaced if someone wants it
* Debugger for PC (with single step execution, breakpoints, etc.)
* Debugger for BB3 (with single step execution, breakpoints, etc.)The EEZ flow will start to be usable as soon as the next milestone is finished. Execution on BB3 (i.e. its MCU module) opens up the possibility to design a display module like Nextion that will be completely open source.

Here are the first screenshots:

Fabulous progress - well done to all! :clap:

As work on EEZ flow has continued, we already have the first runtime results: this is a functional flow that reads voltage and current from an external device and displays them on the screen. Commands are MEAS:VOLT? and MEAS:CURR? The set delay between two readings is 500 ms. If the delay is not set the reading speed is up to 160 times per second!

New thing for today is added support for popular Plotly graphs. This means that through EEZ flow data will be able to be presented in a variety of attractive ways. Here is the first example with flip between EEZ Flow frontend and backend. Again, this is not a simulation, this is what can be seen on the screen when the flow is started and communicates with an external device (EEZ BB3 in this case, but it can be any other instrument that supports SCPI).
