Adding new driver for SparkFun 9DoF Razor IMU M0

[der-b]

Hi,

for a DIY VR-Device i use the SparkFun 9DoF Razor IMU M0. Therefore I implemented a new driver for OpenHMD and i would like to share my code with you project.

Kind regards,

Bernd

Awesome, will go over review this weekend, you seem to have the first Diy driver so will talk with the team to see how our policy is on this. Have you written some form of article on your device? Would be cool to see!

lol, i was literally just asking about DIY position tracking on the irc channel ;)

I don't have an article yet. I build the first prototype some days ago. I also adapted arcan and safespaces to work with my device. Before i write an article about it i like to push back all the necessary changes i had to made and get some working experiences.

The device i build is based on three components:

1. A VR-Set for smartphones (in my case the DESTEC V4 VR)
2. A 2K 5.5 inch display from china
   • ebay
3. SparkFun 9DoF Razor IMU M0

I used tape to put everything together (see images).

PS: One of the issues of the build is, that the display has a resolution of 1440x2560 because it is intended for smartphones. That means the height is greater as the width. Therefor the screen rotated by 90 degree. Unfortunately, while implementing software for VR this is often not expected.

kind regards

[buzztiaan]

cant you just output a 90 degree rotated output from your videocard?

something like ; xrandr --output HDMI-2 --rotate left

and this is totally what i want to do aswell, but starting from a cardboard version :)

Discussed this within the community, We allow pulling in drivers like this, but the build flags need to be provided a bit differently.

We will also require Meson and CMake compilation (which is both easy to add), before adding to master.
The Autotools flag would be driver-community-sparkfun9dof
The CMake flag would be OPENHMD_COMMUNITY_SPARKFUN9DOF.
Since this has a external dependency on Arduino and Arduino libraries, it should be disabled by default.
New dependencies are always calculated in heavily and something like this is to heavy to require by default for a special use case.

I think i implemented your requirements.

Has this part of the project progressed at all, or has it died? I already have a SparkFun 9DoF Razor IMU M0 board & screen, but can't find any links to the article on how to build it, or any instructions.

@der-b Can you rebase this on master and fix the conflicts with master?
