1、功能说明
    1、通过DVP接口从摄像头采集数据，并在TFT_LCD上实时显示。
    2、支持单色和彩色模式，通过DVP_demo.h中的宏 DVP_IMAGE_FORMAT 来选择
            DVP_IMAGE_FORMAT = DVP_IMAGE_FORMAT_GRAY:  单色
            DVP_IMAGE_FORMAT = DVP_IMAGE_FORMAT_RGB565：彩色

        8、LCD背光控制端口：PD6

    使用方法：
        在KEIL下编译后烧录到全功能板，通电，可在LCD上实时看到摄像头捕获的图像。
        切换单色和彩色模式需要修改宏DVP_IMAGE_FORMAT后重新编译烧录。


4、注意事项
    无


1. Function description
	1. Collect data from the camera through DVP interface and display it in real time on TFT_LCD.
	2. support monochrome and color mode, by DVP_IMAGE_FORMAT macro DVP_demo.h to select
		DVP_IMAGE_FORMAT = DVP_IMAGE_FORMAT_GRAY: monochrome
		DVP_IMAGE_FORMAT = DVP_IMAGE_FORMAT_RGB565: colors

2. Use environment
	Software development environment: KEIL MDK-ARM V5.26
    
	Hardware environment:
		1. based on the full function board N32G457QEL-EVB V1.2 development
		2. camera: GC0308 (640*480)
		3. TFT_LCD (320*240 driver: ILI9341)

3. Instructions for use
	System configuration;
		1. Clock source: HSE+PLL
		2. System clock: 144MHz
		3. DMA: DMA2 channel 8
		4. MCO: PA8
		5. DVP port:
			PE2: HSYNC	PE3: VSYNC	PE4:PCLK
			PE5: D0		PE6: PC0 D1, D2	PB2: D3
			PF12: D4		PF13: D5	PF14: D6	PF15: D7
		6. Camera control port: PA8:MCLK PA15:RESET PB7:PWDN PB8:SCL PB9:SDA
		7. ILI9341 Port:
			CS: PB7	DC: PG0	WR: PD5	RD: PD4
			D0: PD14	D1: PD15	D2: PD0	D3: PD1
			D4: PE7	D5: PE8	D6: PE9	D7: PE10
			D8: PE11	D9: PE12	D10: PE13	D11: PE14
			D12: PE15	D13: PD8	D14: PD9	D15: PD10
		8. LCD backlight control port: PD6
	Usage:
		After compiling in KEIL, burn to the full function board, power on, you can see the real-time image 	captured by the camera on the LCD.
		Switching between monochrome and color mode requires modifying the macro 			DVP_IMAGE_FORMAT to recompile and burn.

4. Precautions
	None
