Hat Joystick

SKU:U073

Description

Hat Joystick is a joystick module designed specifically for the M5StickC. It is embedded with an STM32F030F4 main control chip and uses the I2C communication protocol to transmit data with the host M5StickC. This mini-sized joystick module supports full-angle deviation and center pressing, outputting angle deviation data and switch digital signals. It adopts the unified plug-in design of the HAT series for reliable connection with the M5StickC, providing more human-computer interaction input experiences in the most streamlined way.

Protocol

I2C Address: 0x38

Registers:

0x01 Read Only 4 bytes, single-axis value 0 ~ 4096

0: x-axis raw data lower 8 bits

1: x-axis raw data upper 8 bits

2: y-axis raw data lower 8 bits

3: y-axis raw data upper 8 bits

0x02 Read Only 3 bytes

0: x-axis converted data (-127 ~ 127)

1: y-axis converted data (-127 ~ 127)

2: 0 or 1 (button pressed is 0, released is 1)

0x03 Write Only 1 byte

0x00: Normal mode

0x01: Center point calibration

0x02: Maximum value calibration (manually rotate the joystick to get the maximum value)

0x03: Save center point and maximum value data to flash, restore to normal mode after saving
