@par Application Description
|
||
|
||
This directory contains a set of source files that implement a simple "animation"
|
||
application based on STemWin for STM32F7xx devices.
|
||
|
||
The application shows the capability of STemWin to do different animations of different objects independently.
|
||
|
||
How to interact with the application
|
||
------------------------------------
|
||
- The application is an automatic run.
|
||
- It will show 3 objects animated independently: the dog, the cloud and a balloon
|
||
- It will loop infinetly.
|
||
|
||
@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 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,
|
||
then it is highly recommended to enable the CPU cache and maintain its coherence at application level.
|
||
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
|
||
It is also possible to configure the MPU as "Write through", to guarantee the write access coherence.
|
||
In that case, the MPU must be configured as Cacheable/Bufferable/Not Shareable.
|
||
Even though the user must manage the cache coherence for read accesses.
|
||
Please refer to the AN4838 “Managing memory protection unit (MPU) in STM32 MCUs”
|
||
Please refer to the AN4839 “Level 1 cache on STM32F7 Series”

@par Hardware and Software environment
|
||
|
||
- This application runs on STM32F769xx devices.
|
||
|
||
- This application has been tested with STMicroelectronics STM32769I-EVAL
|
||
eval boards 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
|
||
- Run the application
