Will this trackball work with Hyperpixel 4.0 touch's ic2 port? #4

Open hammiesam opened 4 years ago

hammiesam commented 4 years ago

I recently bought this trackball and I've tried to hook it up via my hyperpixel's ic2 port at the back of the screen. I haven't gotten it working yet, I'm also curious, as I'm a bit confused with the readme. What are the exact lines of code i need to input into the terminal to install the necessary components to get this trackball to work? Thank you for any advice, I hope to get this thing working!

Sorry, seem to have missed this request. Have you managed to get it working since?

I believe the HyperPixel4 i2c port is available on bus 3, but you can find which by running ls /dev/i2c-*

Then when you create an instance of the TrackBall class, you should pass in the right bus number, ie:

trackball = TrackBall(i2c_bus=3)

Hi there, thanks for your help.

Do you have a tutorial on how to make the the trackball work with an arduino pro micro (or i guess an adafruit trinket or something). I tried following the instructions, but cannot get it to work at all.

We do not- we don't have first party support for those devices for better or worse. Ordinarily I'd be up for helping you get it up and running- the library for the trackball is quite simple and should be easy enough to port- but I'm long out of experience with these platforms and (given current worldwide circumstances) I don't have any access to hardware.

@hammiesam I haven't yet had a chance to experiment with this and turn it into a mouse but this repo seems to have gotten most of the heavy lifting done already tseary / TrackBall His demo only uses the trackball to control the built in LED but it looks like all the parts are there to integrate it with arduinos mouse libs.
