* stm32: implements ltdc frambuffer and support for ltdc layer operationGregory Nutt2014-12-191-265/+2714
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements the framebuffer support for the generic nuttx framebuffer interface, (see nuttx/video/fb.h) This also implements the interface to perform hardware accelerated layer operation by the ltdc controller and dma2d controller later (see nuttx/video/ltdc.h). The following methods are supported by the ltdc interface: - getvideoinfo Get video information of the layer - getplaneinfo Get plane information of the layer - getlid Handle specific layer identifier. This allows to detect to current layer state (e.g. important for layer flipping) - setclut Set the layer color lookup table. Up to 256 color entries supported. - getclut Get the layer color lookup table - setcolor Set the default layer color. In the context of the ltdc layer this means set the default color outside the active area or if the layer is disabled. - getcolor Get the default layer color - setcolorkey Set the layer colorkey (chromakey). Colorkey is enabled by blendmode LTDC_BLEND_COLORKEY - getcolorkey Get the layer colorkey - setalpha Set the constant alpha value. If blend mode LTDC_BLEND_SRCPIXELALPHA or LTDC_BLEND_DESTPIXELALPHA is defined than the blended color is calculated by the formel: Cdest = Pixelalpha * Constalpha * Csrc. Otherwise: Cest = Constalpha * Csrc - getalpha get the alpha value - setblendmode Set the layer blendmode. Supported blendmodes: non blendmode (do not perform blend operation independent on the layers alpha and colorkey) alpha alpha blending (transparency) destpixelalpha use pixel alpha value for the top layer (Layer2) srcpixelalpha use pixel alpha value for the subjacent layer (Layer1) colorkey enable colorkey - getblendmode Get the layer blendmode - setarea Set the active layer area, the visible rectangle inside the whole layer. This also allows to change the position of the whole layer which is visible in the selected area independent on the area position. - getarea Get the active layer area - update Reload the layer shadow register and make changes visible. Also supports layer flipping. Note! Dithering and background color are static parameter and can only changed at build time. Implementation details: The implementation of ltdc interface was inspired by SDL and DirectFB. All layer settings are shadowed before they become active (except setclut). They are still inactive until the layer is updated. This is done by the update method. Should clut only active after an update or not? Clut is used for drawing while the other settings usually used for blend or blit operations. So i think this should be the right way. The implementation of ltdc interface was inspired by SDL and DirectFB. All layer settings shadowed before they become active (except clut). They are still inactive until the layer is updated. This is done by the update call. Should clut only activated after an update or not? Clut is used for draw operation while the other settings usually used for blend or blit operations. So i think this should be the right way. Deviations from the ltdc hardware implementation: - Shadow register update of both layer (Layer1 or Layer2) is independent as long LTDC_UPDATE_SIM is not set. This flag allows to update both layer simultaneous. Otherwise only the desired layer is updated. Layer operation: Keep in mind, both layer are allways active (of course if both enabled by the configuration). First the Layer 1 is blended with the background color and the result is blended with the Layer2. To avoid blend effects, set the Layer2 in non blend mode. This is equal to blend with alpha = 255. Enable blending of Layer2 with the background color by enable blending of Layer1 and disable the opacity by setting the alpha value to 0. Layer flip: A layer flip usual mean swapping two framebuffer. So the current inactive buffer can refreshed with data while the active framebuffer is visible. A flip operation changes the inactive layer to the active one and vice versa. The ltdc implementation supports layer flip. This can be done by the update call and the flag LTDC_UPDATE_FLIP. In this case ltdc makes the inactive layer invisible. In detail, the inactive layer is disabled and the blendmode reset. Detection of the current layer state (e.g. active or inactive) is supported by the getlid method combined with one of the LTDC_LAYER_* flags. Maybe an additional method "flip" for flip operation should be added to the ltdc interface? But this make no sence from my view if the layer is a non LTDC layer, e.g. playing with dma2d only. Supported and tested nuttx pixel formats: Single Layer without LTDC interface support: - FB_FMT_RGB8 (cmap support required) - FB_FMT_RGB16_565 - FB_FMT_RGB24 Single Layer with LTDC interface support: - FB_FMT_RGB8 (cmap support required) - FB_FMT_RGB16_565 - FB_FMT_RGB24 Dual Layer with LTDC interface support: - FB_FMT_RGB8 (cmap support required) - FB_FMT_RGB16_565 - FB_FMT_RGB24 Why is FB_FMT_ARGB8888 missing? Changes: - Remove unused register debug method. Todo: - Add support for backlight, currently not neccessary Did i forgot something? Take a look in the ltdc example or the interface description (see nuttx/include/video/ltdc.h). Thanks to Ken for the base layout. ;) Signed-off-by: Marco Krahl <ocram.lhark@gmail.com>
