micropython-max31855

This project provides a MicroPython driver for the MAX31855 thermocouple amplifier, enabling temperature measurement from thermocouples via SPI communication. It allows embedded systems running MicroPython to interface with industrial-grade temperature sensors for monitoring and control applications.

Key Features

• SPI Interface — Communicates with MAX31855 chips using standard SPI protocol
• Temperature Reading — Reads thermocouple temperature in Celsius with 0.25°C resolution
• Cold Junction Compensation — Automatically compensates for reference junction temperature
• Fault Detection — Identifies thermocouple faults like open circuits or short circuits
• Simple API — Provides clean methods to read temperature and check fault status

Philosophy

The driver follows MicroPython's minimalist approach, offering a straightforward interface to the MAX31855's capabilities without unnecessary abstraction layers.
