* Defines a second interface for the dma2d controller. Controlling both LTDC ↵Gregory Nutt2015-04-161-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and DMA2D was unpractical from the programmers view because both controllers are to different. LTDC only controls the display visibility but the DMA2D controller changes the content of the frame buffer (buffer of the layer). The main features are: 1. DMA2D interface Supports the nuttx pixel formats: - FB_FMT_RGB8 - FB_FMT_RGB24 - FB_FMT_RGB16_565 Dynamic layer allocation during runtime for the supported formats - The number of allocatable layer can be configured. Supported dma2d operation: - blit (Copy content from source to destination layer) also works with selectable area. - blend (Blend two layer and copy the result to a destination layer wich can be a third layer or one of the source layer) also works with selectable area. - fillarea (Fill a defined area of the whole layer with a specific color) As a result of that the dma2d controller can't transfer data from the core coupled memory, CCM is disabled but usable by the ccm allocator. Currently the ccm allocator is used for allocating the layer structurei only. For the dma memory (layers frame buffer) memory is allocated from heap 2 and 3. 2. LTDC interface I have changed the api for the currently non implemented operations: - blit (Copy content from a dma2d layer to an ltdc layer) also works with selectable area. - blend (Blend two dma2d layer and copy the result to a destination ltdc layer) also works with selectable area. Note! ltdc layer is a layer referenced by the ltdc interface. dma2d layer is a layer referenced by the dma2d interface. One of the most important questions for me was, How can i flexible use an ltdc layer with the dma2d interface, e.g. as source layer for dma2d operations? Get the layer id of the related dma2d layer by a special flag when using getlid() function of the ltdc interface and use the layer id to reference the specific dma2d layer by the dma2d interface. The ltdc coupled dma2d layers are predefined and can't be dynamically allocated of freed. They use the same frame buffer memory and the same color lookup table. Changes: - layer internal format of the clut table - interrupt handling for register reload (vertical vblank) instead using waiting loop - small fixes and refactoring From Marco Krahl.

* The STM32F4Discovery board doesn't come with a Low speed external oscillator ↵Gregory Nutt2015-03-291-2/+0
| | | | | | | | | | | | so the default LSE source for the RTC doesn't work. In stm32_rtcc.c the up_rtcinitialize() logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call that rightfully enables the lsi clock; but the next times, when the rtc is already setup, the rtc_resume() call does NOT start the lsi clock! The right place to put LSE/LSI initialisation is inside stm32_stdclockconfig() in stm32fxxxxx_rcc.c. Doing this I checked the possible uses of the LSI and the LSE sources: the LSI can be used for RTC and/or the IWDG, while the LSE only for the RTC (and to output the MCO1 pin).. This change is not verifed for any other platforms. From Leo Aloe3132
