Originally created by @droogmic on GitHub (Jul 4, 2018).

The discovery book is an amazing resource, but it uses very specific hardware.
I want to make a similar book but for the micro:bit (and only needing the micro:bit), as it is a board specifically made for teaching, and I think has wider availability and is cheaper. I have also explicitly tried to use a different structure and style where it made sense, just to see if it would work better.
If you want to take a look at a very early state: https://github.com/droogmic/microrust, obviously contributions are welcome.
I'd appreciate some help with the licensing though, as I don't want to infringe on japaric's copyright.

Off to a very nice start! Let me know if you need some content or support in the microbit crate. Happy to help out where I can.

NB: The matrix LED could use a driver, it's a bit annoying to use bare bones. OTOH there's already a driver for the sensor so it would be great to have one or more examples using the accelerometer.

@therealprof Thanks! I am new to embedded and rust myself, so this is quite a bit of me just documenting along the way... Sorry for competing with your blog and thanks for the crate, I may make a PR or two in the future ;P

I see the MAG3110 magnetometer driver, but I cant see an accelerometer driver?

I am aware the LED display is a pain to use, I was planning on using that as a source of teaching exercises to demonstrate the necessity of timers, delays etc. maybe (slowly) implement a simple interface for it over the course of the book.

No harm, no foul. I'm happy that someone is picking up the stuff and doing something useful with it.

Hm, interesting; I thought I committed the mma8653fc driver but obviously not. The values I got out of this didn't really make sense to me so I didn't pursue but I think I have to revive it now.

Delays won't help. Displaying anything useful requires a proper scan line algorithm (which requires somewhat strict timing). And it's not a 5x5 matrix either so it requires some odd mapping. I started implementing this but at some point lost interest due to limited utility to me.
