Talk:Wii/wiimote

From Wiire

U6 is most likely a microcontroller based on the 8051, from the ROM analysis found on SparkFun's page.

U6 looks like the audio DAC / decoder. The 8051 code is for the Broadcom chip.

U6 info

According to http://www.wiili.org/index.php/Talk:Wiimote/Hardware they think U6 is a "BU7849" from Rohm, this page: http://www.rohm.com/news/061107.html mentions that they have provided chips for the Wii, as well as this page: http://money.cnn.com/magazines/fortune/storysupplement/wiiremote/index.htm (flash, cannot direct link) labels that IC as by Rohm, but they seem to think it's an ADC for audio...but there's no mic, is there?? probably just a crappy article. - Davr 22:17, 16 December 2007 (MST) I understand its ROHM ADPCM decoder User: Dflam]

From someone who did a silly playaround ....,,....,,...

My father has finally got his bluetooth dongle working again and asked me to bring out one of my wii remote to the lounge . It did show up on the computer but it wont be likely that it bee used on the computer . Thats all for now from richardson j

Bluetooth communications

I know that not many people may have thought of this, but is it possible to reverse the wiimote to pc mouse idea and make a pc mouse function (albeit limitedly) as a wiimote? For example the IR pointer on the wii would move when the mouse moved? I think a link between the mouse and a micro-controller (teensy usb?) that was then processed and sent to the wii cloning an IR signal might work... Would the bluetooth on the wii even support that?

It seems to me that it would be quite easy to find the I2C two wire interface - and remove the broadcom chip master - this would immediately allow to replace it with an external master - say an arduino - without need to desolder or any other change. I also think other lines would be exposed and could be connected
