OV3640-VGA预览初始化寄存器配置

1、寄存器初始化配置说明：

VGA大小（640*480）、YUV422格式（YVYU顺序）、15fps

2、初始化代码

void OV3640_Reset(void)
{
    OV3640_WriteReg(0x3012, 0x80);
}void OV3640_VGAConfig(void)
{
    uint32_t i;unsigned short sensor_reg = 0;/*摄像头复位*/OV3640_Reset();HAL_Delay(50);for(i=0; i<(sizeof(ov3640_15fps_VGA)/4); i++){
    OV3640_WriteReg(ov3640_15fps_VGA[i][0], ov3640_15fps_VGA[i][1]);HAL_Delay(10);sensor_reg = OV3640_ReadReg(ov3640_15fps_VGA[i][0]);if(ov3640_15fps_VGA[i][1] !=sensor_reg){
    printf("init err\r\n"); }}printf("OV3640_VGAConfig\r\n");
}
