Hello,
in fact I added support for a donated LiDE 80 first. Having the
real device to work on is more practical and fun than remote access.
There is also the fact that G124+ chips datasheet isn't available.
This means more reverse engineering on one side, and the other side, I
didn't make my mind on how to handle this since other chips registers
are known.
Regards,
Stef
