- * @brief LTDC HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the LTDC peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- * + Peripheral Control functions
- * + Peripheral State and Errors functions
- *

- ==============================================================================
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Program the required configuration through the following parameters:
- the LTDC timing, the horizontal and vertical polarity,
- the pixel clock polarity, Data Enable polarity and the LTDC background color value
- using HAL_LTDC_Init() function
-
- (#) Program the required configuration through the following parameters:
- the pixel format, the blending factors, input alpha value, the window size
- and the image size using HAL_LTDC_ConfigLayer() function for foreground
- or/and background layer.
-
- (#) Optionally, configure and enable the CLUT using HAL_LTDC_ConfigCLUT() and
- HAL_LTDC_EnableCLUT functions.
-
- (#) Optionally, enable the Dither using HAL_LTDC_EnableDither().
-
- (#) Optionally, configure and enable the Color keying using HAL_LTDC_ConfigColorKeying()
- and HAL_LTDC_EnableColorKeying functions.
-
- (#) Optionally, configure LineInterrupt using HAL_LTDC_ProgramLineInterrupt()
- function
-
- (#) If needed, reconfigure and change the pixel format value, the alpha value
- value, the window size, the window position and the layer start address
- for foreground or/and background layer using respectively the following
- functions: HAL_LTDC_SetPixelFormat(), HAL_LTDC_SetAlpha(), HAL_LTDC_SetWindowSize(),
- HAL_LTDC_SetWindowPosition(), HAL_LTDC_SetAddress.
-
- (#) To control LTDC state you can use the following function: HAL_LTDC_GetState()
-
- *** LTDC HAL driver macros list ***

- (+) __HAL_LTDC_DISABLE_IT: Disable the specified LTDC interrupts.
- (+) __HAL_LTDC_GET_IT_SOURCE: Check whether the specified LTDC interrupt has occurred or not.
-
- [..]
- (@) You can refer to the LTDC HAL driver header file for more useful macros
