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.
RS232 / Serial Support
Re: RS232 / Serial Support
I found this several months ago when working with Arduino communication.
Not mine.
This may help with your syntax and setup.
cheers

Private Sport As SerialPort
Const None As Integer = 0
Private RxLen As Integer
Private Rx As String
Public Sub Form_Open()
Sport = New SerialPort As "Sport"
Sport.PortName = "/dev/ttyACM0" 'Linux serial port to ttyUSB0
Sport.Speed = "9600"
Sport.Parity = 0
Sport.DataBits = "8"
Sport.StopBits = "1"
Sport.FlowControl = 0
Sport.Open()
End
Public Sub Sport_Read()
Try Read #Sport, Rx, Lof(Sport)
If Error Then
Goto NoRx
Endif
RxLen = InStr(Rx, Chr(13))
LabelRxlen.Text = RxLen
ListBox1.Add(Rx)
NoRx:
Rx = ""
End
Please post your serial comm code if you get it working. There are not many working examples kicking around.cheers
