CyberBlades

BeatSaber is a brilliant, fantastic VR game (Steam link). The community has created a number of plugins for it, my favorite of which is HttpStatus created by opl-. It opens up a web server that serves a WebSockets stream of data which provides all kinds of data about the running game. The reason I love their plugin so much is beacuse opl- understands exactly what kind of information would be important to export. It is perfectly documented, easily understood, just a total pleasure to work with.

This is where CyberBlades comes in: It is a historian application that connects to BeatSaber/HttpStatus. Via a simple UI (this currently is emulated via SDL for development and against libcairo/framebuffer) you can select multiple people (this is not something that is yet implemented in BeatSaber and it's kindof annoying, because we usually have multiple people playing and don't want to sign out/sign in every time).

The historian then essentially (for now) records all raw event data that HttpStatus provides and writes them to files.

Where is this going?

I love data and I love analytics. I want to see how I improved in songs over time. I'm looking to hook up a heart rate monitor to my Raspberry Pi and enrich the data with the heart rate of the current player. I want to create plots, plots, plots of songs over time, improvement of performance of the same song over time, etcetc. I want the Pi to emit data in various electronic hardware elements (e.g., LED ring progress meters or similar).

That said, it's in a very early development stage and currently not meant yet for public use. Bear with me, please.

Installation Instructions for Raspberry Pi

I'm using a Raspberry Pi 3B+ with a noname (AliExpress) 2.4" ILI9341 320x240 pixel display board. Here are the steps to set it up:

dd the Raspbian Lite image on your microSD card. I've tested it with 2019-07-10-raspbian-buster-lite.img.
Touch /boot/ssh to activate the OpenSSH server once you turn your Pi on (or attach a keyboard/monitor otherwise).
Boot the Pi for the first time, change the default credentials and put your ssh public key into /root/.ssh/authorized_keys on the Pi.
Log into the Pi and install some dependencies: apt-get intstall git cmake build-essential

Get the display to run. For my case, I used the fbcp-ili9341 driver. I built it with

$ cmake -DSPI_BUS_CLOCK_DIVISOR=6 -DILI9341=ON -DGPIO_TFT_DATA_CONTROL=22 -DGPIO_TFT_RESET_PIN=27 -DSTATISTICS=0 ..

and configured my /boot/config.txt like this:

hdmi_group=2
hdmi_mode=87
hdmi_cvt=320 240 60 1 0 0 0
hdmi_force_hotplug=1

Reboot the Pi, then start the fbcp-ili9341 application. If your display driver works, while that application is running you should now be able to do
```
dd if=/dev/zero of=/dev/fb0
```
to clear the display or
```
dd if=/dev/urandom of=/dev/fb0
```
to show some random garbage.

Acknowledgements

opl- -- you totally rock. Thank you so much for building your amazing BeatSaber plugin and making it possible for non-C# people to build cool stuff.
juj -- you too! What a great and simple-to-use display driver for the Raspberry Pi, so incredibly well documented. Works like a charm, thanks!

What's with the name?

One time my wife couldn't remember the name of BeatSaber and called it "CyberBlades". I love the name and we use it all the time now as an inside joke. So now CyberBlades is something "official" :-)
