lypinator 0:bb348c97df44 15 ##### How to use this driver #####
lypinator 0:bb348c97df44 16 ==============================================================================
lypinator 0:bb348c97df44 17 [..]
lypinator 0:bb348c97df44 18 (#) Program the required configuration through the following parameters:
lypinator 0:bb348c97df44 19 the LTDC timing, the horizontal and vertical polarity,
lypinator 0:bb348c97df44 20 the pixel clock polarity, Data Enable polarity and the LTDC background color value
lypinator 0:bb348c97df44 21 using HAL_LTDC_Init() function
lypinator 0:bb348c97df44 22
lypinator 0:bb348c97df44 23 (#) Program the required configuration through the following parameters:
lypinator 0:bb348c97df44 24 the pixel format, the blending factors, input alpha value, the window size
lypinator 0:bb348c97df44 25 and the image size using HAL_LTDC_ConfigLayer() function for foreground
lypinator 0:bb348c97df44 26 or/and background layer.
lypinator 0:bb348c97df44 27
lypinator 0:bb348c97df44 28 (#) Optionally, configure and enable the CLUT using HAL_LTDC_ConfigCLUT() and
lypinator 0:bb348c97df44 29 HAL_LTDC_EnableCLUT functions.
lypinator 0:bb348c97df44 30
lypinator 0:bb348c97df44 31 (#) Optionally, enable the Dither using HAL_LTDC_EnableDither().
lypinator 0:bb348c97df44 32
lypinator 0:bb348c97df44 33 (#) Optionally, configure and enable the Color keying using HAL_LTDC_ConfigColorKeying()
lypinator 0:bb348c97df44 34 and HAL_LTDC_EnableColorKeying functions.
lypinator 0:bb348c97df44 35
lypinator 0:bb348c97df44 36 (#) Optionally, configure LineInterrupt using HAL_LTDC_ProgramLineEvent()
lypinator 0:bb348c97df44 37 function
lypinator 0:bb348c97df44 38
lypinator 0:bb348c97df44 39 (#) If needed, reconfigure and change the pixel format value, the alpha value
lypinator 0:bb348c97df44 40 value, the window size, the window position and the layer start address
lypinator 0:bb348c97df44 41 for foreground or/and background layer using respectively the following
lypinator 0:bb348c97df44 42 functions: HAL_LTDC_SetPixelFormat(), HAL_LTDC_SetAlpha(), HAL_LTDC_SetWindowSize(),
lypinator 0:bb348c97df44 43 HAL_LTDC_SetWindowPosition(), HAL_LTDC_SetAddress.
lypinator 0:bb348c97df44 44
lypinator 0:bb348c97df44 45 (#) Variant functions with “_NoReload” post fix allows to set the LTDC configuration/settings without immediate reload.
lypinator 0:bb348c97df44 46 This is useful in case when the program requires to modify serval LTDC settings (on one or both layers)
lypinator 0:bb348c97df44 47 then applying(reload) these settings in one shot by calling the function “HAL_LTDC_Reload”
lypinator 0:bb348c97df44 48
lypinator 0:bb348c97df44 49 After calling the “_NoReload” functions to set different color/format/layer settings,
lypinator 0:bb348c97df44 50 the program can call the function “HAL_LTDC_Reload” To apply(Reload) these settings.
lypinator 0:bb348c97df44 51 Function “HAL_LTDC_Reload” can be called with the parameter “ReloadType”
lypinator 0:bb348c97df44 52 set to LTDC_RELOAD_IMMEDIATE if an immediate reload is required.
lypinator 0:bb348c97df44 53 Function “HAL_LTDC_Reload” can be called with the parameter “ReloadType”
lypinator 0:bb348c97df44 54 set to LTDC_RELOAD_VERTICAL_BLANKING if the reload should be done in the next vertical blanking period,
lypinator 0:bb348c97df44 55 this option allows to avoid display flicker by applying the new settings during the vertical blanking period.
lypinator 0:bb348c97df44 56
lypinator 0:bb348c97df44 57
lypinator 0:bb348c97df44 58 (#) To control LTDC state you can use the following function: HAL_LTDC_GetState()
