4.7 Wheel Module Trouble Shooting
z
Wheel Control signals from Main Board
- The signals of DBB are HALL1_OUT, HALL2_OUT, HALL_PDN for wheel operation
- The signals of DBB are SENSOR_INT, SENSOR_I2C_SCL, SENSOR_I2C_SDA,
WHEEL_RESET for touch operation
- The signals of DBB are LED_I2C_SCL, LED_I2C_SDA, WHEEL_RESET for LED control around
the wheel
