How can I read temperature from a MAX31855K Thermocouple?

[jazzpeh]

I am trying to read temperature output from my connected thermocouple sensor. I am using a breakout (MAX31855K Thermocouple Breakout) module which is not supported by johnny-five at the moment. Are there any ways to make this work?

Here's the link to the setup that I did: https://learn.sparkfun.com/tutorials/max31855k-thermocouple-breakout-hookup-guide/all

Thanks!

The MAX31855K is an SPI (Serial Peripheral Interface) device but Johnny-Five currently doesn't support SPI.

Relates issues:
rwaldron/io-plugins#3
Protocol:SPI

Are there any ways to make this work?

It may be possible to bit bang SPI using Pin objects.

Two paths you could pursue to add support:

1. Contribute to firmata and add SPI Add SPI firmata/arduino#245
2. Create a component backpack for this device http://johnny-five.io/news/introducing-i2c-component-backpacks/

Hi @jazzpeh ,

Johnny-Five contributors and maintainers are loathe to close issues where someone has a need. We don't want anyone to ever feel that we don't care, but we just haven't gotten to this feature yet. Rather than leave it languishing as an open issue we have created a Requested Features page and added your request for the MAX31855K there.
