「WiimoteLibを使う」第三話～加速度計再び～

      2015/10/24

先回のボタンの状態の取得に続き、今回は加速度センサーの情報を取得する。といっても、ぼぼ前回のプログラムのコピペでよくて…
加速度取得のプログラム


Imports Microsoft.VisualBasic
Imports System
Imports System.Drawing
Imports System.Drawing.Imaging
Imports System.Windows.Forms
Imports WiimoteLib
Public Class Form1
Private Delegate Sub UpdateWiimoteStateDelegate(ByVal args As WiimoteChangedEventArgs)
Private wm As New Wiimote
Public Sub New()
InitializeComponent()
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
wm.Connect()
wm.SetReportType(InputReport.ButtonsAccel, True)　’←注１
wm.SetLEDs(False, True, True, False)
AddHandler wm.WiimoteChanged, AddressOf wm_WiimoteChanged
End Sub
Private Sub wm_WiimoteChanged(ByVal sender As Object, ByVal args As WiimoteChangedEventArgs)
UpdateState(args)
End Sub
Public Sub UpdateState(ByVal args As WiimoteChangedEventArgs)
BeginInvoke(New UpdateWiimoteStateDelegate(AddressOf UpdateWiimoteChanged), args)
End Sub
Private Sub UpdateWiimoteChanged(ByVal args As WiimoteChangedEventArgs)
Dim ws As WiimoteState = args.WiimoteState
Label4.Text = ws.AccelState.Values.X　’←注２
Label5.Text = ws.AccelState.Values.Y
Label6.Text = ws.AccelState.Values.Z
End Sub
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As FormClosingEventArgs) Handles MyBase.FormClosing
wm.SetLEDs(False, False, False, False)
wm.Disconnect()
End Sub
End Class

変更点は２つだけ！
注１：ReportのタイプをBottonsからButtonsAccelに。でないと、リアルタイムの値取得ができない様子。
注２：前回ボタンの情報を呼び出していた部分をごりっと削除。加速度をLabel4-6に書き出します。
FormにLabel4-6をつくると、こんな感じ。

加速度の値は重力加速度を1として出力されている様子。リモコンからは＋4G～-4Gを256段階の16進数が送られてくるはず、なので、32に1を割り当てている感じ…か。しかし、これでは数字が目まぐるしく変化して捉えづらい。と、いうことで…WiimoteLibを使ったWiikskを制作。Wiiksk0.45にあった書き出し機能がないなど幾分ごまかしているところはあるものの、「すぐに繋がる」点で、幾分改善が。

(2010.11.17追記)　なぜか動きません！私のPCでは動きますが…なぜ？
プログラム部分はこんな感じ。あちこち要改善な部分あり。
