Windows IoT VB .NET을 사용하는 GPL GPIO

Question

작은 프로그램을 사용하여 모든 설정이 올바르게되었는지 확인하려고합니다. 그러나 "GPIO"를 참조하는 모든 것에 대해 오류가 발생합니다 (의견 참조) 또한 "이미 Windows IoT Extensions for UWP"를 참조했습니다. - 도움을 주셔서 감사합니다.

Imports Windows.Devices.Gpio 'Imports statement is unnecessary 

Public NotInheritable Class MainPage 
Inherits Page 
Private gpio 
Private pin As GpioPin 'ERROR: GpioPin is not defined 
Private Const LED_PIN = 18 

Private Sub button_Click(sender As Object, e As RoutedEventArgs) Handles button.Click 
    Call TurnLedOnOff() 
End Sub 

Private Sub TurnLedOnOff() 

     'Check if gpio was already initialied 
     If gpio Is Nothing Then 
      gpio = GpioController.GetDefault 'ERROR: GpioController is not declared 
     End If 

     'Check if LED's pin was already initialied 
     If pin Is Nothing Then 
      pin = gpio.OpenPin(LED_PIN) 
      pin.Write(GpioPinValue.Low) 'ERROR: Not Declared 
      pin.SetDriveMode(GpioPinDriveMode.Output) 'ERROR: Not Declared 
     End If 

     'Read pin status and invert state 
     If pin.Read = GpioPinValue.High Then 'ERROR: Not Declared 
      pin.Write(GpioPinValue.Low) 'ERROR: Not Declared 
     Else 
      pin.Write(GpioPinValue.High) 'ERROR: Not Declared 
     End If 
    End Sub 
End Class

은 당신이 개발 환경의 문제를 가지고처럼

If gpio Is Nothing Then 
    gpio = GpioController.GetDefault.openpin(LED_PIN) 
end if
