@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) Program the required configuration through following parameters:
the Transfer Mode, the output color mode and the output offset using
HAL_DMA2D_Init() function.
(#) Program the required configuration through following parameters:
the input color mode, the input color, input alpha value, alpha mode
and the input offset using HAL_DMA2D_ConfigLayer() function for foreground
or/and background layer.
*** Polling mode IO operation ***
=================================
[..]
(+) Configure the pdata, Destination and data length and Enable
the transfer using HAL_DMA2D_Start()
(+) Wait for end of transfer using HAL_DMA2D_PollForTransfer(), at this stage
user can specify the value of timeout according to his end application.
*** Interrupt mode IO operation ***
===================================
[..]
(#) Configure the pdata, Destination and data length and Enable
the transfer using HAL_DMA2D_Start_IT()
(#) Use HAL_DMA2D_IRQHandler() called under DMA2D_IRQHandler() Interrupt subroutine
(#) At the end of data transfer HAL_DMA2D_IRQHandler() function is executed and user can
add his own function by customization of function pointer XferCpltCallback and
XferErrorCallback (i.e a member of DMA2D handle structure).
-@- In Register-to-Memory transfer mode, the pdata parameter is the register
color, in Memory-to-memory or memory-to-memory with pixel format
conversion the pdata is the source address and it is the color value
for the A4 or A8 mode.
-@- Configure the foreground source address, the background source address,
the Destination and data length and Enable the transfer using
HAL_DMA2D_BlendingStart() in polling mode and HAL_DMA2D_BlendingStart_IT()
in interrupt mode.
-@- HAL_DMA2D_BlendingStart() and HAL_DMA2D_BlendingStart_IT() functions
are used if the memory to memory with blending transfer mode is selected.
(#) Optionally, configure and enable the CLUT using HAL_DMA2D_ConfigCLUT()
HAL_DMA2D_EnableCLUT() functions.
(#) Optionally, configure and enable LineInterrupt using the following function:
HAL_DMA2D_ProgramLineEvent().
(#) The transfer can be suspended, continued and aborted using the following
functions: HAL_DMA2D_Suspend(), HAL_DMA2D_Resume(), HAL_DMA2D_Abort().
(#) To control DMA2D state you can use the following function: HAL_DMA2D_GetState()
*** DMA2D HAL driver macros list ***
=============================================
[..]
Below the list of most used macros in DMA2D HAL driver.
(+) __HAL_DMA2D_ENABLE: Enable the DMA2D peripheral.
(+) __HAL_DMA2D_DISABLE: Disable the DMA2D peripheral.
(+) __HAL_DMA2D_GET_FLAG: Get the DMA2D pending flags.
(+) __HAL_DMA2D_CLEAR_FLAG: Clears the DMA2D pending flags.
(+) __HAL_DMA2D_ENABLE_IT: Enables the specified DMA2D interrupts.
(+) __HAL_DMA2D_DISABLE_IT: Disables the specified DMA2D interrupts.
(+) __HAL_DMA2D_GET_IT_SOURCE: Checks whether the specified DMA2D interrupt has occurred or not.
[..]
(@) You can refer to the DMA2D HAL driver header file for more useful macros
