JoyC missing documentation
-
I miss some descriptions and/or a schematic, to understand details of JoyC:
-
Which pins from the StickC are used by the JoyC, which are available for other purposes?
(I guess only 2 pins are used for SDA/SCL, so one should be available) -
Also, i wonder what the Battery on JoyC does. Does it power the stick, or does it only drive the JoyC?
-
What is the switch doing?
I can see that the led's are turned on and off, but does it also have other effects?

-
I think there is a switch pin in addition to SDA and SCL (the joystick is pressed or not)
-
The battery can power the Stick, and StickC and StickCPlus can read the battery voltage, but StickCPlus2 cannot
-
I personally adopt that the switch could just powering the LEDs...or STM32 on JoyC?
