I got a TinySaber at the Detroit Maker Faire last weekend.
(my wife also got a Tiny Piano )

using arduino IDE 1.8.5
board: "TineSaber Rev2"
programmer: "arduino as ISP"

trying to upload the sample TinySaber code.
the sample code does verify.

this is the output from upload attempt.

Code Select Expand

Running Digispark Uploader...
Plug in device now... (will timeout in 60 seconds)
Warning: device with unknown new version of Micronucleus detected.
This tool doesn't know how to upload to this new device. Updates may be available.
Device reports version as: 2.3

What am I doing wrong here. 
Thanks for any help.

Roger.

Hello Roger,

Do you know what version of Zadig you downloaded? This may have something to do with the error you received.

Please let me know if a version fix helps or if it's still not uploading!

Thanks,
Réna

Thanks for reply Réna,

I did not download version of Zadig ( USB driver )
That appeared to be for Windows machines.

Seems I have left out an important detail, my operating system. Sorry.
running Ubuntu 16.04
( Also tried it on Linux Mint 17 , similar results. j
I do not have easy access to Windows , but probably can find one if I have to.

I was able to get past this error by downloading a more recent copy of micronucleus from here
https://github.com/micronucleus/micronucleus/releases
and replacing the micronucleus binary that the ArduinoIDE was using with the new micronucleus binary.
Mine was in ~/home/johnpaul/.arduino15/packages/TinyCircuits/tools/micronucleus/2.0a4/
It is 2.0a4 because that's what the tinycircuits JSON from the instructions requests.

After this, when I uploaded the sample code from the TinyCircuits site, the text display and saber modes broke.
Rainbow mode and flashlight mode still worked.

I narrowed the problem to the board not getting good accelerometer data. It seemed to think it was constantly getting a double tap and also wasn't reacting to x motion changes for text.

I physically unplugged the battery, then pushed the reset button a few times. When I plugged the battery back in, it properly works with the accelerometer again and all example modes work.
