MicroPython Library for MAX31856 (Precision Thermocouple to Digital Converter with Linearization) with 19-Bit Thermocouple Temperature Resolution. This chip provides a SPI digital interface for Thermocouple Types B, E, J, K, N, R, S or T.

A "ripoff" of the original work of Stephen P. Smith. Original code is here: https://github.com/steve71/MAX31856

Tested with:

Connections:

Feather HUZZAH ESP8266 GND to MAX31856 GND

Feather HUZZAH ESP8266 3.3V output to MAX31856 Vin (voltage input)

Feather HUZZAH ESP8266 SCK (serial clock, GPIO14) to MAX31856 SCK (serial clock)

Feather HUZZAH ESP8266 MISO (master input, GPIO12) to MAX31856 SDO (serial data output)

Feather HUZZAH ESP8266 MOSI (master output, GPIO13) to MAX31856 SDI (serial data input)

Feather HUZZAH ESP8266 GPIO15 to MAX31856 CS (chip select)

To upload the module on ESP8266 use (on MacOS) "ampy --port /dev/tty.SLAB_USBtoUART put max31856.py" or WebREPL: https://docs.micropython.org/en/latest/esp8266/esp8266/quickref.html#webrepl-web-browser-interactive-prompt
