@par Description

This application shows how to implement a sample demonstration example allowing 
to show some of the STemWin Library capabilities.

The list of modules to be used is configured into the file Demo/GUIDEMO.h

All the demo modules are running sequentially. Throughout the demonstration, a
control frame window is displayed at the bottom right of the touch screen: it
includes a progress bar and two control buttons (Next + Halt) allowing to skip
or pause the currently running module.

LED 1  continuously toggling to indicate that the Demo runs properly.

@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 needs to ensure that the SysTick time base is always set to 1 millisecond
      to have correct HAL operation.

@note Care must be taken when HAL_RCCEx_PeriphCLKConfig() is used to select the RTC clock source; in this 
      case the Backup domain will be reset in order to modify the RTC Clock source, as consequence RTC  
      registers (including the backup registers) and RCC_BDCR register are set to their reset values.

@Note<74>If the user code size exceeds the DTCM-RAM size or starts from internal cacheable memories (SRAM1 and SRAM2),that is shared between several processors,
 <20><><A0><A0><A0>then it is highly recommended to enable the CPU cache and maintain its coherence at application level.
<0A><><A0><A0><A0><A0>The address and the size of cacheable buffers (shared between CPU and other masters)  must be properly updated to be aligned to cache line size (32 bytes).

@Note It is recommended to enable the cache and maintain its coherence, but depending on the use case
<0A><><A0><A0><A0> It is also possible to configure the MPU as "Write through", to guarantee the write access coherence.
