/** ****************************************************************************** * @file stm32f4xx_hal_dma2d.c * @author MCD Application Team * @version V1.1.0 * @date 19-June-2014 * @brief DMA2D HAL module driver. * 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 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. -@- 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: 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 has occurred or not. [..] (@) You can refer to the DMA2D HAL driver header file for more useful macros @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2014 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
