B4R Question Set Int Array from Inline C

[hatzisn]

This code fails. Can anyone tell me why:

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

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
    Public Serial1 As Serial
    Dim b(8) As Int
    Dim tim As Timer
    
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    SetBArray
    Log(b(0))
    Log(b(1))
    Log(b(2))
    tim.Initialize("tim_Tick", 1000)
End Sub

Sub tim_Tick
    
End Sub

Sub SetBArray
    RunNative("setb", Null)
End Sub

#if C
void setb (B4R::Object* o) { 
    b4r_main::_b[0] = B11111100;
    b4r_main::_b[1] = B01100000;
    b4r_main::_b[2] = B11111111;
}
#End If

Thank you thetahsk for your answer. I will try that a.s.a.p. Meanwhile I am wondering about this piece of code:

((byte*)b4r_main::_b->data)

I understand (I think) what It does partially. I think it casts the b4rmain::_b to byte but I cannot understand the "->data" part. What does it do?

 

[tigrot]

b is an object, array of bytes, data is data part (forgive the calebur) of array, which is indexed as well. There is also a descriptor in the object, to mark the number of elementi.
