版本：V1.0

 

 

1、配置全志平台的android所能感知的摄像头的分辨率（预览/拍照）：

Q:\a33\hm1375_sc3817r_sina33_rtl8188eu\android\device\softwinner\astar-y3\configs\camera.cfg

used_preview_size = 1

key_support_preview_size = 1280x1024, 1280x720, 640x480

key_default_preview_size = 640x480

 

used_picture_size = 1

key_support_picture_size = 1280x1024, 1280x720, 640x480

key_default_picture_size = 640x480

 

 

 

 

2、在系统启动的时候自动加载himax1375的驱动模块：hm1375.ko：

Q:\a33\hm1375_sc3817r_sina33_rtl8188eu\android\device\softwinner\astar-y3\init.sun8i.rc

#csi module

insmod /system/vendor/modules/videobuf-core.ko

insmod /system/vendor/modules/videobuf-dma-contig.ko

insmod /system/vendor/modules/cam_detect.ko

#insmod /system/vendor/modules/actuator.ko

#insmod /system/vendor/modules/ad5820_act.ko

insmod /system/vendor/modules/cci.ko

insmod /system/vendor/modules/vfe_os.ko

insmod /system/vendor/modules/vfe_subdev.ko

#insmod /system/vendor/modules/gc0307.ko

#insmod /system/vendor/modules/ov2035.ko

#insmod /system/vendor/modules/ov2640.ko

#insmod /system/vendor/modules/ov5640.ko

insmod /system/vendor/modules/hm1375.ko

insmod /system/vendor/modules/vfe_v4l2.ko

 

 

 

 

3、（可选操作）

Q:\a33\hm1375_sc3817r_sina33_rtl8188eu\android\device\softwinner\astar-y3\ueventd.sun8i.rc

/dev/video0               0660   media      media

#/dev/video1               0660   media      media

 

 

 

 

4、驱动相关：

Q:\a33\hm1375_sc3817r_sina33_rtl8188eu\lichee\linux-3.4\drivers\media\video\sunxi-vfe\device\hm1375.c

Q:\a33\hm1375_sc3817r_sina33_rtl8188eu\lichee\linux-3.4\drivers\media\video\sunxi-vfe\device\Makefile

obj-m+= hm1375.o

 

（不加这里会运行出错：）

Q:\a33\hm1375_sc3817r_sina33_rtl8188eu\lichee\linux-3.4\drivers\media\video\sunxi-vfe\sensor_info.c

struct sensor_item sensor_list_t[] =

{

//         name                  i2c_addr               sensor type               sensor size          sensor max pclk

{"hm1375",0x48,SENSOR_YUV, PIXEL_NUM_2M, CORE_CLK_RATE_FOR_2M},

{ "hm5065" , 0x3e, SENSOR_YUV ,  PIXEL_NUM_5M , CORE_CLK_RATE_FOR_5M},

{ "ov2640" , 0x60, SENSOR_YUV ,  PIXEL_NUM_2M , CORE_CLK_RATE_FOR_2M},

{ "ov5640" , 0x78, SENSOR_YUV ,  PIXEL_NUM_5M , CORE_CLK_RATE_FOR_5M},

……

{ "ov7736" , 0x42, SENSOR_YUV ,  PIXEL_NUM_0_3M , CORE_CLK_RATE_FOR_2M},

};
