| * This file provides firmware functions to manage the following |
| * functionalities of the DMA2D peripheral: |
| * + Initialization and de-initialization functions |
| * + IO operation functions |
| * + Peripheral Control functions |
| * + Peripheral State and Errors functions |
| * |
| @verbatim |
| ============================================================================== |
| ##### 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 HAL_DMA2D_RegisterCallback() to register a user callback. |
| |
| (#) Function 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 HAL_DMA2D_UnRegisterCallback() to reset a callback to the default |
| weak (surcharged) function. |
| 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 HAL_DMA2D_Init and if the state is HAL_DMA2D_STATE_RESET |
| all callbacks are reset to the corresponding legacy weak (surcharged) functions: |
| examples HAL_DMA2D_LineEventCallback(), HAL_DMA2D_CLUTLoadingCpltCallback() |
| Exception done for MspInit and MspDeInit callbacks that are respectively |
| reset to the legacy weak (surcharged) functions in the HAL_DMA2D_Init |
| and HAL_DMA2D_DeInit only when these callbacks are null (not registered beforehand) |
| If not, MspInit or MspDeInit are not null, the HAL_DMA2D_Init and 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 HAL_DMA2D_RegisterCallback before calling HAL_DMA2D_DeInit |
| or 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. |
