USB reading/writing as Com port

[Marc Venken]

I spend the every looking and testing samples to read the USB port from FW

I did not succeed.

I can read/write arduino serial data from the Node-Red application from USB port 5. So it is possible to collect data from a Arduino true a USB port. How to read this data from it ?
Maybe it is important to have a usb to com hardware in FW ? But other programs seems to manage them from the USB port.

Any Help ?

Generally, when it is necessary to manage a device that connects via the USB port but responds to a serial structure, there are serial port emulators.
Here in Argentina, there are fiscal drivers that use that functionality, and they can be managed with Fivewin's COM port management functions.

Thanks, So i looked and find a program link CoolTerm, Free, Small and doing what you say. I have to test it this evening.

But it is software, so mayby FiveWin has also a Lib for this ? If I plugin my handscanner, FW can read this and it is also on a USB, but I suppose that this is not the same.

So If Coolterm is needed, I will have a txt/csv file that is updated very fast in realtime, and I can put my Arduino data into the file.

How will FW capture the data from that file (this is updated) and show result in a FW dialog. Just Open if with a fOpen function ? FW will be fast enough ?

My goal is to manage my Arduino RobotArm with FW design Dashboard. FW on Top )) !!
