============================================================================== + ##### How to use this driver ##### + ============================================================================== + [..] + The LTDC HAL driver can be used as follows: + + (#) Declare a LTDC_HandleTypeDef handle structure, for example: LTDC_HandleTypeDef hltdc; + + (#) Initialize the LTDC low level resources by implementing the HAL_LTDC_MspInit() API: + (##) Enable the LTDC interface clock + (##) NVIC configuration if you need to use interrupt process + (+++) Configure the LTDC interrupt priority + (+++) Enable the NVIC LTDC IRQ Channel + + (#) Initialize 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 + + *** Configuration *** + ========================= + [..] + (#) 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_ProgramLineEvent() + 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() and HAL_LTDC_SetAddress(). + + (#) Variant functions with _NoReload suffix allows to set the LTDC configuration/settings without immediate reload. + This is useful in case when the program requires to modify serval LTDC settings (on one or both layers) + then applying(reload) these settings in one shot by calling the function HAL_LTDC_Reload(). + + After calling the _NoReload functions to set different color/format/layer settings, + the program shall call the function HAL_LTDC_Reload() to apply(reload) these settings. + Function HAL_LTDC_Reload() can be called with the parameter ReloadType set to LTDC_RELOAD_IMMEDIATE if + an immediate reload is required. + Function HAL_LTDC_Reload() can be called with the parameter ReloadType set to LTDC_RELOAD_VERTICAL_BLANKING if + the reload should be done in the next vertical blanking period, + this option allows to avoid display flicker by applying the new settings during the vertical blanking period. + + + (#) To control LTDC state you can use the following function: HAL_LTDC_GetState() + + *** LTDC HAL driver macros list *** + ============================================= + [..] + Below the list of most used macros in LTDC HAL driver. + + (+) __HAL_LTDC_ENABLE: Enable the LTDC. + (+) __HAL_LTDC_DISABLE: Disable the LTDC. + (+) __HAL_LTDC_LAYER_ENABLE: Enable an LTDC Layer. + (+) __HAL_LTDC_LAYER_DISABLE: Disable an LTDC Layer. + (+) __HAL_LTDC_RELOAD_IMMEDIATE_CONFIG: Reload Layer Configuration. + (+) __HAL_LTDC_GET_FLAG: Get the LTDC pending flags. + (+) __HAL_LTDC_CLEAR_FLAG: Clear the LTDC pending flags. + (+) __HAL_LTDC_ENABLE_IT: Enable the specified LTDC interrupts. + (+) __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 + + + *** Callback registration *** + ============================================= + [..] + The compilation define USE_HAL_LTDC_REGISTER_CALLBACKS when set to 1 + allows the user to configure dynamically the driver callbacks. + Use function HAL_LTDC_RegisterCallback() to register a callback. + + [..] + Function HAL_LTDC_RegisterCallback() allows to register following callbacks: + (+) LineEventCallback : LTDC Line Event Callback. + (+) ReloadEventCallback : LTDC Reload Event Callback. + (+) ErrorCallback : LTDC Error Callback + (+) MspInitCallback : LTDC MspInit. + (+) MspDeInitCallback : LTDC MspDeInit. + [..] + This function takes as parameters the HAL peripheral handle, the callback ID + and a pointer to the user callback function. + + [..] + Use function HAL_LTDC_UnRegisterCallback() to reset a callback to the default + weak function. + HAL_LTDC_UnRegisterCallback() takes as parameters the HAL peripheral handle + and the callback ID. + [..] + This function allows to reset following callbacks: + (+) LineEventCallback : LTDC Line Event Callback + (+) ReloadEventCallback : LTDC Reload Event Callback + (+) ErrorCallback : LTDC Error Callback + (+) MspInitCallback : LTDC MspInit + (+) MspDeInitCallback : LTDC MspDeInit. + + [..] + By default, after the HAL_LTDC_Init and when the state is HAL_LTDC_STATE_RESET + all callbacks are set to the corresponding weak functions: + examples HAL_LTDC_LineEventCallback(), HAL_LTDC_ErrorCallback(). + Exception done for MspInit and MspDeInit functions that are + reset to the legacy weak (surcharged) functions in the HAL_LTDC_Init() and HAL_LTDC_DeInit() + only when these callbacks are null (not registered beforehand). + If not, MspInit or MspDeInit are not null, the HAL_LTDC_Init() and HAL_LTDC_DeInit() + keep and use the user MspInit/MspDeInit callbacks (registered beforehand). + + [..] + Callbacks can be registered/unregistered in HAL_LTDC_STATE_READY state only. + Exception done MspInit/MspDeInit that can be registered/unregistered + in HAL_LTDC_STATE_READY or HAL_LTDC_STATE_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_LTDC_RegisterCallback() before calling HAL_LTDC_DeInit() + or HAL_LTDC_Init() function. + + [..] + When the compilation define USE_HAL_LTDC_REGISTER_CALLBACKS is set to 0 or + not defined, the callback registration feature is not available and all callbacks + are set to the corresponding weak functions. + + @endverbatim +
