   One of the last pieces of the Wii-Mote to be discovered is it’s speaker. Up until now, nobody has been able to successfully communicate with the speaker to produce sounds. Carl made a post today to the WiiLi forums including a script that will bring the Wii Mote’s speaker to life. Much of the initial work to find the codes to send to the wii-mote was done by Marcan, so a good chunk of the credit for this discovery should go to him.

   Here is the GlovePIE script you will need to test out the Wii-Mote’s Speaker from Windows:

   // Carl Kenner’s Wiimote Speaker Test script! Version 2
   // A = start sound, B = stop sound
   // Minus = decrease sample frequency
   // Plus = increase sample frequency
   // It takes a short time to start (due to delays built into Poke)

   // Change the next line to set the rate at which sound data is sent
   // BUT it must be low enough for the wiimote to respond to the B button
   // it may depend on your PC speed. Must be at least 91 for freq 13.
   pie.FrameRate = 120 Hz

   if not var.initialized then
   var.freq = 13 // Set sample rate = 3640 Hz (so computer can keep up)
   var.volume = 0×40 // volume = 40 ??? Seems to be about max
   debug = var.freq
   var.initialized = true
   end if

   if var.On and (not Wiimote.One) and (not Wiimote.Two) then
   // Report 18, send 20 bytes, square wave, 1/4 sample rate freq
   WiimoteSend(1, 0×18, 20 shl 3, 0xCC,0×33,0xCC,0×33,0xCC,0×33,0xCC,0×33,0xCC,0×33, 0xCC,0×33,0xCC,0×33,0xCC,0×33,0xCC,0×33,0xCC,0×33)
   else if var.On and Wiimote.One then
   // Report 18, send 20 bytes, square wave, 1/2 sample rate freq
   WiimoteSend(1, 0×18, 20 shl 3, 0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3, 0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3,0xC3)
   else if var.On and Wiimote.Two then
   // Report 18, send 20 bytes, square wave, 1/8 sample rate freq
   WiimoteSend(1, 0×18, 20 shl 3, 0xCC,0xCC,0×33,0×33,0xCC,0xCC,0×33,0×33,0xCC,0xCC, 0×33,0×33,0xCC,0xCC,0×33,0×33,0xCC,0xCC,0×33,0×33)

   This is a huge accomplishment and you can bet that soon enough the hackers will be streaming all kinds crappy 4 bit sounds to their wii-motes. Let the fun begin!!!
   Once again Carl, great work!

   Next up is integrating the Speaker functionality into the other Windows Wii-Mote apps, as well as the Linux and OSX wii-mote programs. Developers will want to check out the WiiLi wiki for information on how to initialize the wii-mote speaker and send sounds to it.
