USING THE ST7 USB DEVICE FIRMWARE UPGRADE DEVELOPMENT KIT (DFU-DK)

5.2 DFU DEMONSTRATOR GUI

The graphical user interface in this package is provided as a demonstrator and accesses the

lower layers of the DFU software( ST7DFUPRT.dll and ST7DFU.Dll) to get information related

to the USB device, to initiate DFU operations (Upgrade with or without Upload) and also to dis-

play errors, warnings, debug messages and progress .

A simple GUI is provided to demonstrate the DFU utility. Its main features are the following:

– Select one available USB device and display its properties (ex: Vid, Pid, rev),

– Choose to Upgrade the device and to store its present firmware version,

– Select from the PC browser the new firmware image and the file to be stored,

– Integrate a DFU file generator,

– Start button to start operations,

– Abort button to cancel a programming or read operation.

– Progress tool bar,

– Display all debugging messages (Error messages etc.),

– GUI exit, GUI help.

Note: The DFU demonstrator GUI is written in C++, using MFC in Microsoft Visual C++ 6.0. All

source code, including a project file is included with the DFU-DK package.
