Documentation

This section explains how to use rtd-acquire and, just as importantly, where its responsibility ends.

Using rtd-acquire

Start here for installation, the Measurement result contract, device reads, and error handling.

• Using rtd-acquire
• Installation
• Measurement results
• Reading devices
• Errors and status

Hardware & acquisition

Understand the hardware-facing side of the package and the first supported converter path.

• Hardware & acquisition
• MAX31865
• Raspberry Pi / Linux SPI
• Arduino AVR / HERO adapter
• The acquisition boundary

Measurement & diagnostics

Learn how trustworthy resistance, warning/fault state, normalized diagnostics, native evidence, and resistance uncertainty fit together.

• Measurement & diagnostics
• Diagnostics
• Native evidence
• Resistance uncertainty

Simulation & testing

Exercise application logic and the MAX31865 driver without physical hardware.

• Simulation & testing
• Simulated acquisition
• MAX31865 SPI emulator

Integration

Connect acquisition to rtd-sensor or implement another acquisition device without collapsing the package boundaries.

• Integration
• rtd-sensor
• Implementing acquisition devices
• Hardware integration

Visit the RTD Playground

The Playground remains part of rtd-sensor. It is the companion place to experiment with RTD curves and temperature interpretation after rtd-acquire has produced a resistance.
