Joystick HAT



Joystick HAT is one of the HAT module that is specifically designed for M5StickC. We have used a STM32F030F4 microprocessor inside to implement I2C communication with M5StickC.This mini-volume joystick module supports full angular movement and center press, and outputs angular data as well as button digital signals.With the 'HAT' unified plug-in design it can provide reliable connection, in the most streamlined way. which allowes to get more HMI experience.

Communication protocol

I2C address: 0x38


0x01 Read only 4 bytes, single axis value 0 ~ 4096

0: low 8 bits of raw data on X-axis

1: high 8 bits of raw data on X-axis

2: low 8 bits of raw data on Y-axis

3: high 8 bits of raw data on Y-axis

0x02 only read 3 bytes

0: x-axis data after transform ( -127 ~ 127)

1: y-axis data after transform ( -127 ~ 127)

`2: 0 or 1 (press down 0, release 1).

0x03 only write 1 bytes

0x00: Normal mode

0x01: Central spot set 0

0x02: Maximum Calibration (Require manually rotate the joystick to get the maximum value).

0x03: Save central spot and Maximum Calibration value to flash, and go to Normal Mode after finish.

Joystick calibration method:First i2c writes register 0x03 and then sends 0x02, the joystick is rotated several times around the top, bottom, left and right, and then 0x03 is saved in register 0x03.
