 Hi all,

Does anyone know of a place i can read up on how to use Serial (Rs232) communication with Gambas?

I as As I have a Serial Barcode Reader and I would like to get the data from this and use it with in my Software (I would also need to get the weight from it as it is a scanner / scale like they use in the supermarkers)

Ideal I would like to have the serial scanner not linked to anything like a keypress (or a Do loop like I had to have in DOS)

any information or example website would be welcomed.

I found this several months ago when working with Arduino communication.
Not mine.
This may help with your syntax and setup.

Code (gambas)

  2. Const None As Integer = 0
  5.  
  6. Public Sub Form_Open()
  7.   Sport = New SerialPort As "Sport"
  8.   Sport.PortName = "/dev/ttyACM0" 'Linux serial port to ttyUSB0
  9.   Sport.Speed = "9600"
  10.   Sport.Parity = 0
  11.   Sport.DataBits = "8"
  12.   Sport.StopBits = "1"
  13.   Sport.FlowControl = 0
  14.   Sport.Open()
  16.  
  17. Public Sub Sport_Read()
  18.  
  19.   Try Read #Sport, Rx, Lof(Sport)
  20.  
  21.     If Error Then
  22.       Goto NoRx
  23.     Endif
  24.    
  25.     RxLen = InStr(Rx, Chr(13))
  26.     LabelRxlen.Text = RxLen
  27.     ListBox1.Add(Rx)
  28.  
  29. NoRx:
  30.  
  31.   Rx = ""
  32.  

Please post your serial comm code if you get it working. There are not many working examples kicking around.
cheers
