JOYSTICK, M5Stack has two types of JOYSTICKs: one is compatible with FACES Kit and this one, which is a M5Unit version of ther other JOYSTICK device.
JOYSTICK is very similar to the 'analog' joystick on PS2 (PlayStation 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.
Based on 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.
|X、Y Axis output value range||10-250|
|Z Axis output value range||0-1|
