Demonstration architecture overview

The STM3220G-EVAL demonstration consists of seven sub-demos and uses the emWin

graphical stack for the visual aspect, uC-Host stack and uC-FS for media storage in the

connected USB Flash disk; the embedded touch screen is used as an input device (one

touch mode) and the LCD is used in 16-bit color mode.

2.1

The STM3220G-EVAL demonstration is an interactive application; the navigation within sub-

demos is done by a single touch using a pen or finger on the active touch screen.

2.2

The application starts in text mode until the initialization phase is completed.

Figure 6.

After initializing the hardware, the involved peripherals and the GUI stacks, the main desktop

displays all the available sub-demos through the icon view widget.
