As Mark says you can use VB to do that. Since IVPBrick COM Interface is avilable
now I think it is possible via applet as well.
Here is the sample that you can use with VB. Make sure that you add a reference
to LEGO VPBrick 2.1 type library.
If you need further help please dont hesitate to drop an Email.
Private WithEvents vpb As LEGOVPBrickLib.VPBrick
Private Sub Form_Load()
Set vpb = New LEGOVPBrickLib.VPBrick
Port$ = ""
End Sub
Private Sub FindPort()
On Error GoTo except
vpb.FindPort Port$
txtResult = "Port: " + Port$
Exit Sub
except:
txtResult = "Error " + Hex$(Err.Number) + " " + Err.Description
ErrHelp
End Sub
Private Sub OpenPort()
On Error GoTo except
vpb.Open Port$
txtResult = "Opened " + Port$
Exit Sub
except:
txtResult = "Error " + Hex$(Err.Number) + " " + Err.Description
ErrHelp
End Sub
Private Function SetBrickType(nBrickType As BrickTypes)
Select Case nBrickType
Case Scout
comboBrickType = "Scout"
vpb.BrickType = Scout
Case RCX2
comboBrickType = "RCX2"
vpb.BrickType = RCX2
Case MicroScout
comboBrickType = "MicroScout"
vpb.BrickType = MicroScout
Case Else
comboBrickType.Clear
End Select
End Function
Private Sub cmdTest_Click()
On Error GoTo except
nBrickType = vpb.Status(CheckBrickType)
SetBrickType (nBrickType)
nStatus = vpb.Status(BrickStatus) 'unlocks Scout
If nStatus = StatusReady Then
If nBrickType = Scout Then
vpb.Execute "sound 25"
Else
vpb.Execute "sound 3"
End If
txtResult = "Ok"
Else
txtResult = "Not ready"
End If
Exit Sub
except:
txtResult = "Error " + Hex$(Err.Number) + " " + Err.Description
ErrHelp
End Sub
