ganlikun 0:13413ea9a877 17 ##### How to use this driver #####
ganlikun 0:13413ea9a877 18 ==============================================================================
ganlikun 0:13413ea9a877 19 [..]
ganlikun 0:13413ea9a877 20 (#) Program the required configuration through the following parameters:
ganlikun 0:13413ea9a877 21 the LTDC timing, the horizontal and vertical polarity,
ganlikun 0:13413ea9a877 22 the pixel clock polarity, Data Enable polarity and the LTDC background color value
ganlikun 0:13413ea9a877 23 using HAL_LTDC_Init() function
ganlikun 0:13413ea9a877 24
ganlikun 0:13413ea9a877 25 (#) Program the required configuration through the following parameters:
ganlikun 0:13413ea9a877 26 the pixel format, the blending factors, input alpha value, the window size
ganlikun 0:13413ea9a877 27 and the image size using HAL_LTDC_ConfigLayer() function for foreground
ganlikun 0:13413ea9a877 28 or/and background layer.
ganlikun 0:13413ea9a877 29
ganlikun 0:13413ea9a877 30 (#) Optionally, configure and enable the CLUT using HAL_LTDC_ConfigCLUT() and
ganlikun 0:13413ea9a877 31 HAL_LTDC_EnableCLUT functions.
ganlikun 0:13413ea9a877 32
ganlikun 0:13413ea9a877 33 (#) Optionally, enable the Dither using HAL_LTDC_EnableDither().
ganlikun 0:13413ea9a877 34
ganlikun 0:13413ea9a877 35 (#) Optionally, configure and enable the Color keying using HAL_LTDC_ConfigColorKeying()
ganlikun 0:13413ea9a877 36 and HAL_LTDC_EnableColorKeying functions.
ganlikun 0:13413ea9a877 37
ganlikun 0:13413ea9a877 38 (#) Optionally, configure LineInterrupt using HAL_LTDC_ProgramLineEvent()
ganlikun 0:13413ea9a877 39 function
ganlikun 0:13413ea9a877 40
ganlikun 0:13413ea9a877 41 (#) If needed, reconfigure and change the pixel format value, the alpha value
ganlikun 0:13413ea9a877 42 value, the window size, the window position and the layer start address
ganlikun 0:13413ea9a877 43 for foreground or/and background layer using respectively the following
ganlikun 0:13413ea9a877 44 functions: HAL_LTDC_SetPixelFormat(), HAL_LTDC_SetAlpha(), HAL_LTDC_SetWindowSize(),
ganlikun 0:13413ea9a877 45 HAL_LTDC_SetWindowPosition(), HAL_LTDC_SetAddress.
ganlikun 0:13413ea9a877 46
ganlikun 0:13413ea9a877 47 (#) Variant functions with “_NoReload” post fix allows to set the LTDC configuration/settings without immediate reload.
ganlikun 0:13413ea9a877 48 This is useful in case when the program requires to modify serval LTDC settings (on one or both layers)
ganlikun 0:13413ea9a877 49 then applying(reload) these settings in one shot by calling the function “HAL_LTDC_Reload”
ganlikun 0:13413ea9a877 50
ganlikun 0:13413ea9a877 51 After calling the “_NoReload” functions to set different color/format/layer settings,
ganlikun 0:13413ea9a877 52 the program can call the function “HAL_LTDC_Reload” To apply(Reload) these settings.
ganlikun 0:13413ea9a877 53 Function “HAL_LTDC_Reload” can be called with the parameter “ReloadType”
ganlikun 0:13413ea9a877 54 set to LTDC_RELOAD_IMMEDIATE if an immediate reload is required.
ganlikun 0:13413ea9a877 55 Function “HAL_LTDC_Reload” can be called with the parameter “ReloadType”
ganlikun 0:13413ea9a877 56 set to LTDC_RELOAD_VERTICAL_BLANKING if the reload should be done in the next vertical blanking period,
ganlikun 0:13413ea9a877 57 this option allows to avoid display flicker by applying the new settings during the vertical blanking period.
ganlikun 0:13413ea9a877 58
ganlikun 0:13413ea9a877 59
ganlikun 0:13413ea9a877 60 (#) To control LTDC state you can use the following function: HAL_LTDC_GetState()
