@par Application Description

This application aims to show the outstanding capability of Display Serial Interface (DSI)
periphiral to display images with high resolution (800x480). With a simple movement of finger,
the content of GRAM is directly updated and displayed on DSI LCD.
Thanks to Tearing Effect and Partial refresh features that allow user to provoke
a refresh whenever he wants and on the specified region he desires, the refresh
of LCD is more rapid than any time before.

At the begining, the quadspi is intialized to put images in. Then TS and LCD DSI
are initialized then a first image is displayed.
In this example, the refresh of LCD is made in partial mode (left then right).

Two mode of images draw are possible through this application; vertical draw or
horizontal draw. The default mode is horizontal. User can change the mode by
pressing Tamper button.

By moving the finger on TS, a new image will progressively displayed on LCD while
the old one disapears progresively. When HORIZONTAL_DRAW mode is active, moving
finger left or right causes the display of next or previous image.
When VERTICAL_DRAW mode is active, moving finger up or down causes the display of
next or previous image.

The program runs in infinite loop.

@note Care must be taken when using HAL_Delay(), this function provides accurate
delay (in milliseconds) based on variable incremented in SysTick ISR. This
implies that if HAL_Delay() is called from a peripheral ISR process, then
the SysTick interrupt must have higher priority (numerically lower)
than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.

@note The application need to ensure that the SysTick time base is always set to 1 millisecond
to have correct HAL operation.

@par Hardware and Software environment

- This example runs on STM32F469xx/STM32F479xx devices.

- This example has been tested with STMicroelectronics STM32469I-EVAL
board and can be easily tailored to any other supported device
and development board.

@par How to use it ?

In order to make the program work, you must do the following :
- Open your preferred toolchain
- Rebuild all files and load your image into target memory
- Open STM32 ST-Link Utility V4.1.0, click on "External Loader" from the bar menu then check "MT25Q512A_STM32469I-EVAL" box
- Connect the STM32469I-EVAL board to PC with USB cable through CN22
- Use generated hex file with STM32 ST-Link Utility to program both internal Flash and external QSPI memory
- Run the application
