FreeCAD Workbench that provides a terminal and file upload via USB connection

Here is some time I try to integrate a USB connection in FreeCAD. Thanks to the library PySerial.

There is little time I saw the new Path module with a lot of Python, which allowed me to better organize my files ... Thanks to FreeCAD developers ...

The ultimate goal will be to transfer cn files (Gcode) to a platform in the occurrence a TinyG2 (DUE Arduino + Gshield of Synthetos).

Now I have a connection that runs on a terminal mode. A file upload function... And a position feedback draw in real time on screen...

Besides, any help is welcome
