Hi Mc,

I tried to use the trackball with a pyb405 and a pyb26, and I have the same return:
"
File "test_trackball.py", line 8, in <module>
File "/flash/lib/trackball.py", line 60, in __init__
OSError: [Errno 110] ETIMEDOUT
"
It looks good button...

Yep,
Finally it works with pyb26.

I don't know why it doesn't works with my pyb405, maybe cause by the prototype "Springton hat" ...

Otherwise this trackball is good.
The sensibility is very fine and you can adjust easly add a lots of button's commands.

Thanks.

Yip,

It works on pyb405 too (without the Springton hat wich doesn't let I2C works).

The trackball is nice.

Thanks.

Finally, springton hat work fine. I don't know what happened when I tested it...
It's perfect with the pyb405 which has real interest. For example, I use it with epaper (for raspberry) and the trackball for command display text... Beautifull and perfectly convinient.

Thanks.
