Drawing tristate buttons
Is it possible to detect tristate buttons? normally they are shown like two buttons:
- step 0: button 1 on, button 2 off
- step 1: button 1 off, button 2 off
- step 2: button 1 off, button 2 on
They are named the same swA0, swA1, swA2 so maybe the protocol on /dev/input/js0 can detect that and show the buttons like a real three state button
For reference, this is for RF transmitters:
a Flysky FS-I6X shows tristate buttons but as pairs of two.
