From Dewesoft IOLITE EtherCAT to Arduino openDAQ: Where the Measurement Lab Began
How an IOLITE EtherCAT gateway experiment started FermiLabs’ Arduino and Dewesoft measurement work, and why openDAQ became the shared signal model.
OpenDAQ engineering at FermiLabs: practical SDK integration, device and signal models, Native and LT streaming, reference-domain metadata, interoperability, Linux ARM64 deployment and browser-connected measurement workflows. This archive includes reproducible case studies and technical notes with clearly identified software versions, source repositories, test evidence and limitations. Reference, simulated, replayed and physically measured data are distinguished rather than treated as interchangeable.

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.
