Detailed FermiLabs engineering case studies that explain the original problem, system architecture, implementation, verification, results and lessons learned. Each article identifies the project history and relevant milestone dates, links to authoritative technical evidence, and explains what the tests do and do not demonstrate. Content covers embedded systems, data acquisition, robotics, scientific computing, electronics and software integration.
How FermiLabs built and validated a shared C++/LVGL laboratory on the Arduino GIGA Display Shield — architecture, authentic C64 execution, physical release evidence and remaining qualification gates.
How a 500 kHz four-phase power-electronics requirement became a reusable Arduino UNO Q waveform capability, why programmed and measured signals must stay separate, and how the work connects EFBus, SpeedCircuits and OpenDAQ.
How an IOLITE EtherCAT gateway experiment started FermiLabs’ Arduino and Dewesoft measurement work, and why openDAQ became the shared signal model.
The evolution of EFBus from robot-oriented MCU/Linux transport to a reusable typed acquisition boundary, without conflating EFBus with openDAQ Native.
An evidence-led openDAQ 3.40.3 installation and Native reference-device workflow on Linux ARM64, with exact host and lifecycle qualification.
A reproducible openDAQ 3.40.3/ LT 4.0.3 engineering comparison of channel values and reference-domain metadata across transport boundaries.
How SpeedCircuits combines browser-local ngspice circuit studies with evidence-aware DAQ concepts, preparing a path from simulation to reference and later physical measurement.
A controlled software workflow that records synthetic signals through the actual openDAQ Native SDK and compares them through the FRC Studio reference importer.
How the Arduino GIGA R1 became an eight-channel openDAQ Streaming LT device, with July 2026 hardware measurements and DewesoftM validation.
