I use Neo2 on the OS (Linux) and adapted my firmware to it. I am satisfied so far.
One thing that bothers my a bit is that Neo2 has a different way to lock in CapsLock. In Neo2 a CapsLock behaviour is activated by pressing both shift keys simultaneously. On ordinaty keyboards this sets the CapsLock LED which even the cheapest keyboard has. If I press SHIFT_L+SHIFT_R on my Model01, the CapsLock LED on the other connected keyboard gets activated.
I would like to configure some key’s LED to show whether CapsLock is activated or not. I am quite sure that I would have to catch some OS event. Could anyone give me some hints to get started on this, please?
