View Full Version : wii mote data resolution and sampling rate

10-10-2009, 01:02 AM

can anyone tell me what the raw wiimote data is in terms of resolution (how many bits?) and sampling rate (in HZ?) through OSCulator prior to OSC/MIDI etc. conversions?

Hello Brian,

The X axis of the accelerometers has a precision of 10 bits, Y and Z, 9 bits.

For the nunchuck the accelerometers have a precision of 8 bits in OSCulator 2.8.8, but they will have 10 bits in the next version.

The rate of data reporting is roughly equal to 100 hz. The events are not down-sampled in OSCulator, that means Wiimote messages are received and processed in the application at the same rate as they are sent by the device.

did i miss this info somewhere? is it documented and i did not look hard enough?

thanks much. that's pretty nice data, btw.

Well, this really depends on the various driver implementations, most of them are only 8 bits. I've made sure we can squeeze the last bits of data given by the sensors.

If you want in depth technical information, you can visit wiibrew.org (http://www.wiibrew.org), this is mostly where I get information on the Wiimote and its accessories.

I have not documented the characteristics of the Wiimote on the website though I think it could be a good idea.
