Thursday, 23 July '09: Wii Motion Plus Beta Support

Brian has done it again, check out the following cross-posting from brianpeek.com detailing beta support for the Wii Motion Plus:

I have posted a new version of WiimoteLib as a beta for people to play around with the Wii MotionPlus accessory.  Please note that this is not a stable release and should only be used if you wish to mess around with the MotionPlus.  Also note that only C# source code is included in this release as it is not a final build.  Here’s the change log:

v1.8.0.0

  • Taiko Drum Master’s TaTaCon drum controller supported (Dean Herbert)
  • Bare-bones Wii MotionPlus support (wiibrew.org, testing by Tyler Tolley)
  • WiimoteTest UI changed to add MotionPlus data
    • Please note that the current version is VERY flakey and may not work at all for you.
    • Pair your Wiimote, plug in your MotionPlus, call InitializeMotionPlus()
    • Extensions plugged into the MotionPlus will give wacky results…not supported…yet!
    • Internal changes to perhaps fix some threading issues

So remember, it’s a beta, it may not work for you, and the data you’ll get back from the accessory is just the raw data it provides.  You won’t get real orientation values.

That said, head over to CodePlex and give it a try! (Brian Peek)

Great work Brian!

Tuesday, 14 July '09: Adding Dampened COG to WiimoteLib

Inspired by endquotes WPF implementation of COG I have developed an equivalent system for WiimoteLib that provides the library with facility for Dampened COG output. I find the two systems can be used to compliment each other greatly depending upon the desired application requirement. Before you start this instruction assumes use of a raw copy of WiimoteLib 1.7

Here is how its done:

Open up Data Types.cs and within the public struct BalanceBoardState add the following blocks of code: Read..

Saturday, 11 July '09: Balance Board BMI

Want to be able to calculate your BMI via WiimoteLib so you can use your board ala WiiFit, heres how its done:

Before we start, for a detailed description of BMI please refer to the following Wikipedia article: http://en.wikipedia.org/wiki/Body_mass_index

The formula for calculating BMI is a simple one and can be defined as follows:

BMI = Weight in kilograms / height in meters² – Metric
BMI = (weight in pounds * 703 ) / height in inches² – Imperial

The following function is passed a WiimoteState value ws and returns BMI as a double. The division by 100 is used to convert a cm user_height value into meters and can quite easily be replaced/removed if desired. Read..

Friday, 10 July '09: Real Balance Board Orientation

Today is a good day. After a exactly one year and two days, I have finally cracked the enigma of Balance Board Orientation, and have a version which robust enough for release.

Needless to say I am overjoyed, check out the video:

During the last year I have developed numerous implementations for the task, most of which worked, however none strong enough to deal with the heterogeneous error known as untrained users, however no more!

I am now working on implementing the system fully within both WiimoteLib and the WiiCi driver. Check back soon for more details.

Friday, 19 June '09: Status of Wii MotionPlus Support for WiimoteLib

Here is a Cross Post from brianpeek.com detailing Brian’s current progress with the Wii Motion Plus: Source

Ok, I get about 10 emails a day on this, so I figure a status update is in order.

The Wii MotionPlus extension for the Wiimote was released last week. Since then, I and others have been working to figure out how the device works. Unfortunately, it does NOT work as every other extension controller has worked up until this point, mostly due to the fact that the Wii MotionPlus accessory has an expansion port of its own so all of the other extension controllers can plug into it.

In the past few days, some progress has been made thanks to the folks over at wiibrew.org, although functionality is nowhere near complete. For example, it’s currently impossible to have the Wiimote notify you when the Wii MotionPlus is inserted into the bottom of the Wiimote, like all of the other extension controllers do.

I have been working with the information at wiibrew.org and am trying to get things working reliably with my library so that developers can actually get some degree of functionality out of it.

So, all that said, expect to see a new (likely beta) version of WiimoteLib “soon” that has some bare-bones Wii MotionPlus functionality included. It won’t be perfect, complete, or bug free, but it will allow you to tinker with the device a bit. I will update my blog when the new version is available. Thanks!

Friday, 12 June '09: Wii Motion Plus

Well its Wii Motion Plus release day here i the uk and the stores are full of them, so I had no need to panic about getting hold of one this morning!

The good news is that the device does not crash either WiimoteLib or my WiiCi application and the bad news is that the device does not crash either WiimoteLib or my WiiCi application so I have no place really to start. Read..

Wednesday, 4 February '09: Logic3 FreeBird Working with WiimoteLib

Hi Just to let you know that I have just had some joy with the Logic3 nunchuck and version 1.7 of WiimoteLib.

You must start with the chuck turned off then once everything has been initialized hit the fc paring button and your all systems go.

497-2497-4

The lib views the chuck as the unknown device: a42000000, thus, in order to get it working at this initial stage Read..

Sunday, 25 January '09: Im a PMACC

The truth is I am neither a PC or a Mac, I am a person and in reference believe the ability to chose would be nice, but very unrealistic in the (crossplatform) developer world.

Whats this all about? The adverts piss me off, you know the one’s…

All in all I believe both systems have their benefits and their losses, the only real option is to be a PMACC (Personal Macintosh Computer) and merge the two.

I got VS2008 to work on my Macbook Pro today, long live PMACC..
