Using the EVAL6474H-DISC with the firmware for the GUI

(FWGUI)

By default the discovery board is loaded with the FWGUI. This firmware offers the capability

to connect the board with a GUI: the SPINFamily evaluation tool. This GUI provides direct

access to all L6474 registers and allows sending application commands.

Both the FWGUI and the GUI can be downloaded on the “Design Resources” page of the

L6474.

The FWGUI can be downloaded to the discovery board as detailed in Section 5.2.

The behavior of the GUI is detailed in the “Help.chm” file which is provided with the setup file

of the GUI.

To have a correct execution of the sanity check, please follow the steps below:

Place a jumper on the BOOT pins (bottom left corner of the board):
