Done. The new issue is: https://github.com/hybridgroup/gobot/issues/372
I have also updated my sample code after spotting a stupid mistake. The result is exactly the same however.The code shows no errors and there are no lights n the PiGlow. The updated code is here: https://play.golang.org/p/Xma_6zBtT2 Owen On Mon, 2017-02-20 at 02:37 -0800, Ron Evans wrote: > Hi, Owen > > Thanks for doing some work on this, it look cool. > > > > The current set of Gobot i2c drivers all use the sysfs Read() and Write() interface.

But when the code runs nothing happens.

That libraries test code runs fine on the board, so the PiGlow itself is working ok.
