$REVOLUTION_SDK_ROOT/build/demos/kpaddemo
This sample program verifies the KPAD library's Wii MotionPlus functionality. Using it, you can display any value that is possible to obtain from the library, and you can edit all modifiable values.
| MPLS PRAMS | Edits modifiable parameters using the KPAD library. The following items can be edited: Zero-Point Tolerance, Zero-Point Drift Correction, Attitude Correction, Acceleration Correction, and DPD Correction. The state of each item is also displayed. |
| KPAD DEMO MAN | Explains how to operate the sample demo. |
| ACC | Displays the KPADStatus structure's acc information as a vector expressing the XY dimensions and a vector expressing the ZY dimensions. |
| OBJ | Indicates the position of the object captured by the DPD. The rectangle is the sensor range. |
| MPLS | Indicates the mpls value in the KPADMPStatus structure. The angular velocity for each axis is displayed below as pitch, yaw, and roll vectors. Up is positive, and down is negative. |
| ANGLE | Indicates the angle value in the KPADMPStatus structure. The following angular data for each axis is displayed using circles for the pitch, yaw, and roll. The counterclockwise direction is positive. |
| DIR | Indicates the dir value in the KPADMPStatus structure. A block is displayed to the side, rotated according to the attitude data. |
| MPLSCB | Displayed, together with the reason value, when a callback registered with the KPADSetControlMplsCallback function is called. The display from the most recent call remains on the screen. |
| SMP.RATE | Displays how many registered callbacks of the KPADSetSamplingCallback function are called per second. |
The values can be edited using the digital buttons. Move the cursor with the +Control Pad. Use the A Button to either turn on or increment the selected digit. Use the B Button to either to turn off or decrement the selected digit.
Press the 1 Button on the Wii Remote to call the KPADResetMpls function and reset the internal state of all data processing related to the Wii MotionPlus. Press the 2 Button to call the KPADSetMplsAngle and KPADSetMplsDirection functions and reset the Wii Remote's angle and attitude data.
The sample program starts up the Wii MotionPlus in normal mode immediately after the Wii Remote is paired. Change the operational mode with a Nintendo GameCube Controller connected to P1.
| A Button | Change to normal mode |
|---|---|
| B Button | Change to bypass mode |
| X Button | Change to a mode allowing simultaneous use of the Nunchuk |
| Y Button | Change to a mode allowing simultaneous use of the Classic Controller |
Pressing HOME on the Wii Remote resets the Wii MotionPlus zero point using the KPADStartMplsCalibration function. Calibration processing is performed while the Wii MotionPlus is starting and when its mode is changing.
The color of the block displayed in the center of the screen changes depending on the status of the Wii MotionPlus.
| Bypass mode, not inserted, not connected | Gray |
|---|---|
| Only the Wii MotionPlus is inserted in the Wii Remote | Magenta |
| A Wii MotionPlus and Nunchuk are inserted in the Wii Remote | Orange |
| A Wii MotionPlus and Classic Controller are inserted in the Wii Remote | Green |
| A Wii MotionPlus and an extension controller other than the Nunchuk or Classic Controller are inserted in the Wii Remote | Violet |
In addition, while the KPAD library is calibrating the Wii MotionPlus the block turns semitransparent. It returns to its original color as processing approaches completion.
A block is initially displayed in the center of the screen. This shape is rotated based on the attitude data, using the fulcrum as the center point. The position of the fulcrum can be moved forward and back by three levels with the + and - Buttons on the Wii Remote.
