Usage

To use this driver:

  1. Add in your gfxconf.h: a) #define GFX_USE_GDISP GFXON

  2. To your makefile add the following lines:

	include $(GFXLIB)/gfx.mk
	include $(GFXLIB)/drivers/gdisp/STM32LTDC/driver.mk
  1. Add a board_STM32LTDC.h to you project directory (or board directory) based on one of the templates.

Configuration

Configuration options available in gfxconf.h:

Option Default Description
STM32LTDC_DMA_CACHE_FLUSH GFOFF Whether to flush the DMA cache on DMA2D operations. This will be turned on automatically on certian platforms/systems.
STM32LTDC_USE_DMA2D GFXON Whether to use the DMA2D peripheral for hardware acceleration.
STM32LTDC_USE_LAYER2 GFXOFF Whether to use the 2nd LTDC layer.
STM32LTDC_USE_RGB565 GFXOFF Whether to use RGB565 instead of RGB888.

2nd layer

To use the 2nd LTDC layer, set STM32LTDC_USE_LAYER2 to GFXON in gfxconf.h.

The 2nd layer is exposed as a separate display. Use gdispGetDisplay() to retrieve the individual layers.
