sahilmgandhi 18:6a4db94011d3 21 the LTDC timing, the horizontal and vertical polarity,
sahilmgandhi 18:6a4db94011d3 22 the pixel clock polarity, Data Enable polarity and the LTDC background color value
sahilmgandhi 18:6a4db94011d3 23 using HAL_LTDC_Init() function
sahilmgandhi 18:6a4db94011d3 24
sahilmgandhi 18:6a4db94011d3 25 (#) Program the required configuration through the following parameters:
sahilmgandhi 18:6a4db94011d3 26 the pixel format, the blending factors, input alpha value, the window size
sahilmgandhi 18:6a4db94011d3 27 and the image size using HAL_LTDC_ConfigLayer() function for foreground
sahilmgandhi 18:6a4db94011d3 28 or/and background layer.
sahilmgandhi 18:6a4db94011d3 29
sahilmgandhi 18:6a4db94011d3 30 (#) Optionally, configure and enable the CLUT using HAL_LTDC_ConfigCLUT() and
sahilmgandhi 18:6a4db94011d3 31 HAL_LTDC_EnableCLUT functions.

sahilmgandhi 18:6a4db94011d3 36 and HAL_LTDC_EnableColorKeying functions.
sahilmgandhi 18:6a4db94011d3 37

sahilmgandhi 18:6a4db94011d3 40
sahilmgandhi 18:6a4db94011d3 41 (#) If needed, reconfigure and change the pixel format value, the alpha value
sahilmgandhi 18:6a4db94011d3 42 value, the window size, the window position and the layer start address
sahilmgandhi 18:6a4db94011d3 43 for foreground or/and background layer using respectively the following
sahilmgandhi 18:6a4db94011d3 44 functions: HAL_LTDC_SetPixelFormat(), HAL_LTDC_SetAlpha(), HAL_LTDC_SetWindowSize(),
sahilmgandhi 18:6a4db94011d3 45 HAL_LTDC_SetWindowPosition(), HAL_LTDC_SetAddress.
sahilmgandhi 18:6a4db94011d3 46
sahilmgandhi 18:6a4db94011d3 47 (#) Variant functions with “_NoReload” post fix allows to set the LTDC configuration/settings without immediate reload.
sahilmgandhi 18:6a4db94011d3 48 This is useful in case when the program requires to modify serval LTDC settings (on one or both layers)
sahilmgandhi 18:6a4db94011d3 49 then applying(reload) these settings in one shot by calling the function “HAL_LTDC_Relaod”
sahilmgandhi 18:6a4db94011d3 50
sahilmgandhi 18:6a4db94011d3 51 After calling the “_NoReload” functions to set different color/format/layer settings,
sahilmgandhi 18:6a4db94011d3 52 the program can call the function “HAL_LTDC_Relaod” To apply(Reload) these settings.
sahilmgandhi 18:6a4db94011d3 53 Function “HAL_LTDC_Relaod” can be called with the parameter “ReloadType”
sahilmgandhi 18:6a4db94011d3 54 set to LTDC_RELOAD_IMMEDIATE if an immediate reload is required.
sahilmgandhi 18:6a4db94011d3 55 Function “HAL_LTDC_Relaod” can be called with the parameter “ReloadType”
sahilmgandhi 18:6a4db94011d3 56 set to LTDC_RELOAD_VERTICAL_BLANKING if the reload should be done in the next vertical blanking period,
sahilmgandhi 18:6a4db94011d3 57 this option allows to avoid display flicker by applying the new settings during the vertical blanking period.
sahilmgandhi 18:6a4db94011d3 58
sahilmgandhi 18:6a4db94011d3 59
sahilmgandhi 18:6a4db94011d3 60 (#) To control LTDC state you can use the following function: HAL_LTDC_GetState()
