C++ (Cpp) HBlankInterruptHandler示例

示例#1

文件： VGA.c 项目： darthrake/U23-Library

static void DMACompleteHandler()
{
	GPIOE->BSRRH=0xff00; // Set signal to black.
	DMA2->LIFCR|=DMA_LIFCR_CTCIF1; // Clear interrupt flag.
	StopPixelDMA();

	if(HBlankInterruptHandler) HBlankInterruptHandler();
}

示例#2

文件： VGA.c 项目： skeezix/zikzak

static void DMACompleteHandler()
{
    SetVGASignalToBlack();
    DMA2->LIFCR|=DMA_LIFCR_CTCIF1; // Clear interrupt flag.
    StopPixelDMA();

    if(HBlankInterruptHandler) HBlankInterruptHandler();
    // TODO: VBlank interrupt? At lower priority?
}

示例#3
