I’ve released version 0.9.1 of my Nexus FDX protocol decoder. It does things like read .nxb files a lot quicker than before, handle USB disconnects/reconnects of the GND10 (when running), serial port timeout, and lots of other stuff.
As of an hour ago, it is on pypi and can be installed using “pip install fdxread”.
It should work on your laptop, or on a pi if you prefer. (at least it installs fine on my older armhf jessie system.)
In other news, I’ve created a Wikipedia node for FDX to make it more widely understood: https://en.wikipedia.org/wiki/Fast_Data_eXchange
As I said earlier, if anyone have any FDX capable Nexus gear they’re not using any longer, I would love some actual hardware to play with.
