Engineering guide
For MCU acquisition terminal signal definition, use the sequence below to retain reproducible inputs, actions and exception evidence. This is an implementation method; actual interface names, commands and parameters depend on the target device and version documentation.
Implementation and exception checks
Swipe the table horizontally to view all columns.
| Step | Action and evidence | Exception handling |
|---|---|---|
| Raw data | Define raw counts or message fields, byte order and valid ranges | Represent protocol errors separately from a valid zero |
| Conversion and units | Retain engineering values, units, conversion version and calibration provenance | Without a conversion basis, deliver explicitly identified raw values only |
| Time and status | Distinguish sampling, reporting and display times and include valid, out-of-range and disconnected states | Retain original sample times and states after backfill or reconnection |
What inputs are needed before starting?
Exact sensor and MCU models, signal ranges and units, interfaces and power, sampling targets and reference equipment. Check document versions and availability first and retain missing items as unresolved inputs.
How should delivery and acceptance be defined?
For each channel check raw and converted values, units, time source and error states; bind accuracy conclusions to reference equipment and test conditions separately. Communication, reporting rate and display refresh do not establish measurement accuracy; verify hardware and reference methods separately.
Enterprises in Nanjing, China, can submit these inputs for remote review. Agree prototype integration, sample shipment, site work and associated costs for the specific project.
Review the service scope and submit the project inputs before agreeing on development and delivery. Original Chinese service scope
