I've tried installing MRAA both via apt and building it from its github source. I can run mraa-gpio and mraa-i2c on the commandline, and I can turn LEDs on and off with the GPIO javascript example. But, when I try to run the SPI javascript example, I get an error at the moment of instantiation:

(classic)thosmos@localhost:~/hello-node$ sudo nodejs
> var m = require('mraa');
> x = new m.Spi(0)
Error: Illegal arguments for construction of _exports_Spi

Is there a step I'm missing for getting this working?

  • What hardware is this on?

  • This is on an Intel Joule Commented Jan 31, 2017 at 23:24
  • And running Ubuntu Core 16.04 Commented Jan 31, 2017 at 23:30
  • The Joule is a bit different. I've logged a bug for this issue to be investigated and will report back once I have an answer.

  • Thanks for following up on this. Where was this bug report logged (with Ubuntu, Intel, or somewhere else)? Commented Feb 3, 2017 at 21:39
