B4R Question questions about Wire and other

[newbie]

Hello,

1. question: wire
i have try to transfer the following simple arduino code to B4R:

void myRtcGet()
{ byte rSec, rMin, rHour, rDOW, rDay, rMonth, rYear;

  Wire.beginTransmission(DS3231_I2C_ADDRESS);  // Open I2C line in write mode
  Wire.write(0x00);  // Set the register pointer to (0x00)
  Wire.endTransmission();  // End Write Transmission

  Wire.requestFrom(DS3231_I2C_ADDRESS, 7);  // Open the I2C line in send mode

  rSec  = bcdToDec(Wire.read() & 0x7f);  // Read seven bytes of data
  rMin  = bcdToDec(Wire.read());
  rHour  = bcdToDec(Wire.read() & 0x3f); 
  rDOW  = bcdToDec(Wire.read());
  rDay  = bcdToDec(Wire.read());
  rMonth  = bcdToDec(Wire.read());
  rYear  = bcdToDec(Wire.read());
  setTime(rHour,rMin,rSec,rDay,rMonth,rYear);
}

to

Sub Process_Globals
   'These global variables will be declared once when the application starts.
   'Public variables can be accessed from all modules.
   Private w1 As WireMaster
   Private w1Adress As Int = 0x68
End Sub

Sub GetClockData
  Log("Init Ds3231")
  w1.Initialize
  w1.WriteTo(w1Adress,Array As Byte(0, 0))
 
  Dim data() As Byte = w1.RequestFrom(w1Adress,7)
  If data.Length = 7 Then
  
  Log("Data:",(data))
  Else
  Log("Missing data...")
    Log("Data:",(data))
  End If
End Sub

Why does it not work , i get no data ????

2. second question: make libraries
i have try erel´s cmdline-code to translate the h-file to xml
no errormessage, no file , what is wrong ??
java -jar B4Rh2xml <c:\Arduino 1.5\libraries\Time\Time.h> <f:\B4R\Additional Libraries\rTime.xml>

thanks for any help
Gerd

1. Please use [code]code here...[/code] tags when posting code (you can edit the post and add it).

2. You can only use this tool with libraries that you wrote as required by B4R. You can use inline C to access methods from Time.h. Start a new thread with the API you need to call.

--> Done, let me know what is wrong in the code

--> i will do it
