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!

This is more of a request for clarification than an issue. It's suggested that there's a Raspbian mouse driver for the trackball, but I'm unsure if that's really the case and, if that's so, how to install it.

See above thread on the pimoroni forums. It seems the INT signal is polled? This means this trackball is not suitable for wireless use. Can this be fixed, or is it hardware related?

You specifically advertise this as being "perfect for adding navigation or control to your Raspberry Pi or Arduino projects." Yet you have zero Arduino support for it, not even a basic listing of I2C registers and how to use them unless you're prepared to reverse engineer the python library. An Arduino library would be nice but in the absence of that could you as least document the protocol!

Hi there! The documentation is a bit sparse, so on a fresh Raspbian install neither mouse.py nor evdev-mouse.py run. It would be useful to add the following notes to the docs:

For mouse.py to work, xautomation is required:
sudo apt-get install xautomation

For evdev-mouse.py to work, Python evdev is required:
sudo pip install evdev

A further issue is that, once these requirements are installed, mouse.py fails to compile with a wrong 'maths' statement on line 4. I'm not a Python programmer so can't be of much help on this, unfortunately.

Running the Trackball service install fails with a cannot find module evdev message.
It looks like its installing the python 2 version but looking for the python 3 version.
If I run sudo pip3 install evdev and then rerun sudo ./install-service.sh it then works, and the trackball works on boot up.
This is with the latest Pi OS version.
