Description:
JOYSTICK, we have two types of JOYSTICKs one is build a panle compatible with FACES Kit, this is the M5Unit version of?JOYSTICK
JOYSTICK is very similar to the `analog` joystick on PS2 (Play Statio 2) controllers. The X and Y axes are two 10k potentiometers which control 2D movement by generating analog signals. The joystick also has a push button that could be used for special applications. Therefore, the entire Unit can output X-Y motion signals in both directions and Z direction.
As designed in the schematic, the Joystick X dimension is connected to pin A0 of MEGA328, the Joystick Y dimension is connected to pin A1 on MEGA328, the Joystick Z dimension is connected to pin A2 on MEGA328.
This Unit communicates with the M5Core via the GROVE A interface. It`s I2C address is 0x52. By reading the data transferred from JOSTICK, you can obtain the motion information of JOYSTICK.
