The STSW-OUT3D8G4 firmware runs on the NUCLEO-G431RB development board. It allows the control of the STDES-OUT03DO8 or STDES-OUT04DO8 reference designs using the STSW-IFAPGUI graphical user interface.
The STSW-OUT3D8G4 contains the software routines that enable the USB-based communication between the NUCLEO-G431RB and the system where the STSW-IFAPGUI runs, and the control of the STDES-OUT03DO8 or STDES-OUT04DO8.
The firmware can control up to four expansion boards (X-NUCLEO-OUT03A1 or X-NUCLEO-OUT04A1).
The STSW-IFAPGUI is based on a common engine and several plug-ins designed to communicate through USB connection with the application layer that runs on the NUCLEO-G431RB development board stacked with the expansion board.
