Does Basic in Openoffice spreadsheet include commands to run something similar to the following test sw. eg. Below.
Specifically is "com1 " supported or is there an equivalent in Openoffice Basic?
as in. "Dim Incoming As String = com1.ReadLine()" eg.Below
( the aim is to import real time data from a usb. port to spreadsheet on PC. )


eg.
Function ReceiveSerialData() As String
' Receive strings from a serial port.
Dim returnStr As String = ""

Dim com1 As IO.Ports.SerialPort = Nothing
Try
com1 = My.Computer.Ports.OpenSerialPort("COM1")
com1.ReadTimeout = 10000
Do
Dim Incoming As String = com1.ReadLine()
If Incoming Is Nothing Then
Exit Do
Else
returnStr &= Incoming & vbCrLf
End If
Loop
Catch ex As TimeoutException
returnStr = "Error: Serial Port read timed out."
Finally
If com1 IsNot Nothing Then com1.Close()
End Try

C++, Java, Python, or anything Microsoft has to offer, but not the supplementary StarBasic lingo.
Simply write the data into a text file and handle that with any software able to load text.

It worked with the ancient old versions of the OpenOffice.org, but not work with the newer version of the Apache OpenOffice nor LibreOffice:

You can declare Windows API functions in OOBasic. If you search for VB6 results for what you want - sometimes little translation is needed - so long as a few things like memory pointers aren't used it should run in OO.

I quickly found this,

Edit: if you can't get something to work from within OO automation is another option.

Thanks folks,
That last link looks promising.JeJe.
Any further suggestions most welcome.

Hello,
with python macros , in Openoffice and LibreOffice calc it is possible to acquire data from serial port in real time. Require pyserial package (installed with pip manager of Apso).
it works under Windows and Linux.
Capture shows a calc workbook obtaining RMC dataframes for a serial port GPS every 2 seconds. Python is multi-thread, so you can work in the worksheet while the data are displayed. Friendly, J.P

Only works with LibreOffice >= 7.1 ( last APSO version requirement).
Don't forget to install the last version of APSO (the version with pip manager (ex v1.4.4) ) and install pySerial with the pip manager.
