Development of a system to provide all needs to manage analytical instruments such as surface area by gas adsorption and particle size by laser scanning. Composed by : Custom S.O. : Debian @ Arm hosted on Raspberry 4B or iMx/RT20 (or PC)  User Interface : All JavaFX. Including Window Manager, Android-like widgets/tools, Material-like LAF. - see simpler version @  - PP200 Calculation core/server : Repository of libraries and functions used to do the hard work on instruments math & statistical tasks. The base language is Python (obviously) with Pandas and Scipy. Interfaces with Java UI above via sockets. - see MongoDB interface + Entity Manager & Compiler to it @  PServer_d Calculation Interface/Research: Browser based hook used to help university research people create new functions. Currently uses Jupyter notebooks interfacing with calc. core above. Remote access to calculation core and instrument tools : uses a custom https server (Jetty) to host Angular 7 apps in the local version. It was tested as a portal hosted at Google Cloud. Both Computer engine (with custom image uploaded plus load balance to 4 lanes) and Firebase version passed proof of concept phase. URL is Sorptionlab server - see frontend @  Temps1 Hardware/Firmware and RTOS : uses NXP FRDM K64 Arm M4 core running custom return on completion state machines written in C/C++ (Arm GNU). - see examples @ github.com/msantrax/lgt8 and github.com/msantrax/Picno2 - Interfaces with the user SO via RS232 presently but drivers to talk ethernet/MQTT may be used from our past projects (Android app on tablets see @  Virna7 Ongoing research and not yet implemented are: A simple neural perceptron (Python) to help qualify adsorption isotherms prior analytic procedures and a real-time image pre-processing & feature-id on the edge to help dynamic particle size determination.

Objective: provide hardware, firmware, and analytical user interface to operate a pycnometer able to measure density on ores/cement by gas volumetry compliant to standard ASTM D-2856 and ASTM D-6683. Technologies are : Hardware: All electronics (digital and analog), PCB design, and mechanical drawing were developed in-house. -- Tools used : Proteus8, SolidWorks, and Texas Instruments. - sample drawings @  Picno2 Firmware: Used [Opus-Developed] Antares4 platform (over MBED drivers to ARM/M4) to the stand-alone version and [Opus-Devel] Antares5 platform (over NXP drivers to ARM/K64) to computer-assisted version. See MBED on GNU ARM-EABI C/C++ project codes @  Picno2 Computer Application: The user interface used first the already established [Opus-Devel] Analytical Platform (Java Swing on Netbeans 8.0) working on Windows or Linux. After a big client (CVRD/Brazil) requested to make a multi-instrument interface, it was rebuilt using the new [Opus-Devel] Analytical platform (JavaFX), becoming then project AD100/AD200 after the associated upgrade of hardware and firmware.
