Reverse Engineering of LEGO Mario, Luigi, and Peach
Overview
LEGO Mario as BLE Device
LEGO Mario is a BLE device which supports LEGO Wireless Protocol. It has six input/output devices as follows:
- Port 0:
0x47
Accelerometer, Gesture? - Port 1:
0x49
Color Barcode, RGB Color - Port 2:
0x4a
Pants - Port 3:
0x46
Events, Debug, and something - Port 4:
0x55
??? - Port 6:
0x14
Voltage
Color Barcode
Each color barcode is drawn with five out of nine (eight?) colors. The first two lines are always green and red as header part. The other three lines are data part. The data value can be from 0x01
to 0xd2
. That means there are 0xd2
= 210
(= 7 * 6 * 5
) patterns.
- e.g. is
0x02
. is0xb8
. - How to decode
- See details
Pants
Each pants has a unique 6 bit code. The pants sensor at the bottom of LEGO Mario can detect it physically.
- e.g. The normal Mario's pants is
100001
=0x21
. - See details
