|

Is there a way of getting roll and pitch directly from cwiid libwiimote? I only know how to get accelerometer raw data  do I need to calculate the angles myself????
Thanks! |

Yes, you need to calculate the angles yourself. However, there are examples of how to do this in the wminput plugin sources.

The wiiuse library will calculate pitch, roll, and yaw (if IR is enabled) for you. Check out my sig for the link.
Here's an example of what this would look like in your code:
| Code: | printf("wiimote roll = %f\n", wm->orient.roll);
printf("wiimote pitch = %f\n", wm->orient.pitch);
printf("wiimote yaw = %f\n", wm->orient.yaw); |

You want to know how many gravity forces are being applied to each axis?

humm, i dont know how to say this exatly.
Wiimote can, whem you shake her in X or Y axe speedly , she can make action.
With glovepie, the code is like this :
| Code: |
var.xRot = Wiimote.RawForceX
var.yRot = Wiimote.RawForceY
if var.yRot >= 100 then v = true else v = false
if var.xRot >= 100 then h = true else h = false
|
when i shake my wiimote verticaly (y), i obtain the key "v"
i search everywere, i dont find how to make it with cwiid. |
