##### 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 will call 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().
|
|
|
