==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) Program the required configuration through the following parameters:
the transfer mode, the output color mode and the output offset using
HAL_DMA2D_Init() function.
(#) Program the required configuration through the following parameters:
the input color mode, the input color, the input alpha value, the alpha mode,
the red/blue swap mode, the inverted alpha mode and the input offset using
HAL_DMA2D_ConfigLayer() function for foreground or/and background layer.
*** Polling mode IO operation ***
=================================
[..]
(#) Configure pdata parameter (explained hereafter), 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 pdata parameter, 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 (member
of DMA2D handle structure).
(#) In case of error, the HAL_DMA2D_IRQHandler() function calls the callback
XferErrorCallback.
-@- In Register-to-Memory transfer mode, pdata parameter is the register
color, in Memory-to-memory or Memory-to-Memory with pixel format
conversion pdata is the source address.
-@- Configure the foreground source address, the background source address,
the destination and data length then 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_CLUTLoad() in polling
mode or HAL_DMA2D_CLUTLoad_IT() in interrupt mode.
(#) Optionally, configure the line watermark in using the API HAL_DMA2D_ProgramLineEvent().
(#) Optionally, configure the dead time value in the AHB clock cycle inserted between two
consecutive accesses on the AHB master port in using the API HAL_DMA2D_ConfigDeadTime()
and enable/disable the functionality with the APIs HAL_DMA2D_EnableDeadTime() or
HAL_DMA2D_DisableDeadTime().
(#) The transfer can be suspended, resumed and aborted using the following
functions: HAL_DMA2D_Suspend(), HAL_DMA2D_Resume(), HAL_DMA2D_Abort().
(#) The CLUT loading can be suspended, resumed and aborted using the following
functions: HAL_DMA2D_CLUTLoading_Suspend(), HAL_DMA2D_CLUTLoading_Resume(),
HAL_DMA2D_CLUTLoading_Abort().
(#) To control the DMA2D state, use the following function: HAL_DMA2D_GetState().
(#) To read the DMA2D error code, use the following function: HAL_DMA2D_GetError().
*** 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_GET_FLAG: Get the DMA2D pending flags.
(+) __HAL_DMA2D_CLEAR_FLAG: Clear the DMA2D pending flags.
(+) __HAL_DMA2D_ENABLE_IT: Enable the specified DMA2D interrupts.
(+) __HAL_DMA2D_DISABLE_IT: Disable the specified DMA2D interrupts.
(+) __HAL_DMA2D_GET_IT_SOURCE: Check whether the specified DMA2D interrupt is enabled or not.
*** Callback registration ***
===================================
[..]
(#) The compilation define USE_HAL_DMA2D_REGISTER_CALLBACKS when set to 1
allows the user to configure dynamically the driver callbacks.
Use function @ref HAL_DMA2D_RegisterCallback() to register a user callback.
(#) Function @ref HAL_DMA2D_RegisterCallback() allows to register following callbacks:
(+) XferCpltCallback : callback for transfer complete.
(+) XferErrorCallback : callback for transfer error.
(+) LineEventCallback : callback for line event.
(+) CLUTLoadingCpltCallback : callback for CLUT loading completion.
(+) MspInitCallback : DMA2D MspInit.
(+) MspDeInitCallback : DMA2D MspDeInit.
This function takes as parameters the HAL peripheral handle, the Callback ID
and a pointer to the user callback function.
(#) Use function @ref HAL_DMA2D_UnRegisterCallback() to reset a callback to the default
weak (surcharged) function.
@ref HAL_DMA2D_UnRegisterCallback() takes as parameters the HAL peripheral handle,
and the Callback ID.
This function allows to reset following callbacks:
(+) XferCpltCallback : callback for transfer complete.
(+) XferErrorCallback : callback for transfer error.
(+) LineEventCallback : callback for line event.
(+) CLUTLoadingCpltCallback : callback for CLUT loading completion.
(+) MspInitCallback : DMA2D MspInit.
(+) MspDeInitCallback : DMA2D MspDeInit.
(#) By default, after the @ref HAL_DMA2D_Init and if the state is HAL_DMA2D_STATE_RESET
all callbacks are reset to the corresponding legacy weak (surcharged) functions:
examples @ref HAL_DMA2D_LineEventCallback(), @ref HAL_DMA2D_CLUTLoadingCpltCallback()
Exception done for MspInit and MspDeInit callbacks that are respectively
reset to the legacy weak (surcharged) functions in the @ref HAL_DMA2D_Init
and @ref HAL_DMA2D_DeInit only when these callbacks are null (not registered beforehand)
If not, MspInit or MspDeInit are not null, the @ref HAL_DMA2D_Init and @ref HAL_DMA2D_DeInit
keep and use the user MspInit/MspDeInit callbacks (registered beforehand).
Exception as well for Transfer Completion and Transfer Error callbacks that are not defined
as weak (surcharged) functions. They must be defined by the user to be resorted to.
Callbacks can be registered/unregistered in READY state only.
Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
during the Init/DeInit.
In that case first register the MspInit/MspDeInit user callbacks
using @ref HAL_DMA2D_RegisterCallback before calling @ref HAL_DMA2D_DeInit
or @ref HAL_DMA2D_Init function.
When The compilation define USE_HAL_DMA2D_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registering feature is not available
and weak (surcharged) callbacks are used.
