I’m working on reversing the IR camera in the wiimote. No guarantees about what’s here.<\/p>\n
Pinout:
\n1 – VCC
\n2 – GND
\n3 – ?? GND
\n4 – !enable
\n5 – SCL
\n6 – SDA
\n7 – CLK (24 Mhz from Broadcom chip, turned on when IR sensor is enabled)
\n8 – pulled up to VCC<\/p>\n
i2c protocol:<\/p>\n
address: 1011000<\/p>\n
First the Broadcom chips writes the byte 00110111 to the IR camera. Then reads out data, which seems to be 3 bytes per IR point, 12 bytes total, so probably the same format as the data in the HID report: xxxxxxx yyyyyyy xxyyssss. Unrecognized points are passed as 0xFF.<\/p>\n","protected":false},"excerpt":{"rendered":"
