\DeviceIntegration - This example shows the integration of devices into a UI application and addresses typical questions: How to start a certain action on the target? How to get data from a device?.

\ScreenOrientation - This demo shows, that the orientation of the UI application is independent from the physical orientation of the display.

\ColorFormats - This project demonstrates that every UI application can be generated for different color formats: RGB565, Index8 and LumA44.

\HelloWorld - A very simple project that is useful as starting point and to verify that the entire toolchain, your installation and your board is properly working.

Every project contains the necessary profile settings for the STM32F407 target. Each example is stored in a separate folder containing the entire Embedded Wizard UI project.

\Examples - This folder contains a set of demo applications.

Additionally, this folder contains a configuration file for FreeRTOS and the device driver C/H files used for the DeviceIntegration example.

The file ewconfig.h contains general configuration settings for the target system, like memory ranges and display parameter and configuration settings for the Embedded Wizard Graphics Engine and Runtime Environment. There you will find the initialization of the system and the main loop to drive an Embedded Wizard GUI application. \Source - This folder contains the files main.c and ewmain.c.\Project - This folder contains the prepared projects for GCC (make), IAR Embedded Workbench, Keil MDK-ARM and STM32CubeIDE.You can create your own UI project and generate the code into the subdirectory \GeneratedCode without the need to adapt the project.

All template projects are building the UI application out of this folder.

\GeneratedCode - This folder is used to receive the generated code from an Embedded Wizard UI project.

Don't forget to set the path of your installed STM32CubeProgrammer utility within the file FlashDownload.cfg.

\FlashDownload - This folder contains a script to load the created binaries into the flash of your target by using the STM32CubeProgrammer tool.

The UI design should consider this aspect.

SSD1963 STM32 DRIVER UPDATE

Due to the fact that the display update is done in subsequent updates of small areas, moving graphical objects can cause some tearing effects. Please note: The partial display update is intended to be used for extremely memory-constrained systems. This makes it possible to operate with a scratch-pad buffer of a few kilobytes instead of a full-screen framebuffer within the memory space of the MCU. For this purpose, Embedded Wizard supports a partial display update, that makes it possible to update the display in sequential small areas. As a result, the entire framebuffer can be located inside the display controller and only a small scratch-pad buffer is needed inside the micro-controller (MCU). These types of display controllers can be accessed very fast by using the 16-bit 8080 FSMC data interface and they contain their own display memory. Since the STM32F407 Discovery board does not contain a display onboard, it can be combined easily with an external display controller, like the ILI9325, ILI9341, SSD2119, SSD1963, or others.
