Arquivo: LandzoCamera.c Projeto: MemoriesOff/Freescale

void Camera_init(void)
{
     gpio_Interrupt_init(PORTD,14, GPI_UP,FALLING) ;          //场中断
     gpio_Interrupt_init(PORTD,13, GPI_DOWN, RING) ;          //行中断 
     DMA_PORTx2BUFF_Init (DMA_CH4, (void *)&PTE_BYTE0_IN, BUFF, PTD12,
                          DMA_BYTE1, DATACOUNT, DMA_rising_down); //初始化DMA模块    
}

Exemplo n.º 2

Arquivo: OV7725_binary.c Projeto: Chasingwhat/Self-Balancing-Car

void Ov7725_exti_Init()
{
	//DMA通道0初始化，PTB0上升沿触发DMA传输，源地址为PTD_BYTE0_IN，目的地址为：BUFF ，每次传输1Byte，传输320次后停止传输，保存目的地址不变	
	DMA_PORTx2BUFF_Init(CAMERA_DMA_CH, (void *)&PTB_BYTE0_IN, (void *)IMG_BUFF, PTB8, DMA_BYTE1, 320*2-2, DMA_rising_down_keepon);
	
	DMA_DIS(DMA_CH0);		//先关闭 DMA
	DMA_IRQ_DIS(DMA_CH0);	//不需要使用DMA中断,由行中断来控制DMA传输

	exti_init(PORTA,29,rising_down);	//场中断，内部下拉，上升沿触发中断
	exti_init(PORTA,28,rising_down);	//行中断，内部下拉，上升沿触发中断
