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 | 34 | and HAL_LTDC_EnableColorKeying functions. |
lypinator | 0:bb348c97df44 | 35 | |

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() |
