|
|
Hi,
I want to use wiimote IR camera in my microcontroller project with an atmel avr micro, so I should connect it through I2C bus.
Iwant to know who analyzed IR camera, with what tool he examined I2C bus, and does he has any more information about camera codes and messages?
I don't know is this a right place to ask this question, but unfortunately I didn't find any other forum to ask it?
Thanks.
Jik. |

That stuff was probably captured using a bluetooth sniffer. All the point (pixel position) calculations are done on the wiimote itself, and then the x,y location of each visible IR source is sent over the bluetooth connection. As far as I know (and I don't know much but I've read around a few places) no one has opened the wiimote and analyzed how exactly the chip works. They (or whoever was smart enough to figure this stuff out) reverse engineered the data stream between the wii and wiimote to determine how to activate certain features and what the resulting data means. This documentation is available on both wiili and wiibrew.
