    I'm trying to include HX711 library into inline C code, but I get this error, any suggestions?, Main and HX711 module:


    #Region Project Attributes
    #AutoFlushLogs: True
    #CheckArrayBounds: True
    #StackBufferSize: 300
    #End Region

    Sub Process_Globals
    Public Serial1 As Serial
    End Sub

    Private Sub AppStart
    End Sub
    Sub Process_Globals
    'These global variables will be declared once when the application starts.
        'Public variables can be accessed from all modules.
        Private DataPin,CLKpin As Byte
    End Sub

    Public Sub Begin(sData As Byte , sCLK As Byte)
        DataPin = sData
        CLKpin = sCLK
    End Sub

    Public Sub Tare()
    End Sub

    #If C
    #include <HX711.h>
    void begin(B4R::Object* o) {HX711.begin(b4r_hx711::_datapin,b4r_hx711::_clkpin);}
    void tare(B4R::Object* o) {HX711.tare();}

    #End If

    seems HX711 object is not declared in InlineC code - see the examples of the C library.
    This compiles - but can not test as do not have such a device:
    #If C
    #include <HX711.h>

    HX711 scale;

    void begin(B4R::Object* o)

    void tare(B4R::Object* o)
    #End If
