继续中星微301驱动开发 [复制链接]

在网上下载了2个版本的中星微linux下的驱动，同样是HV7131b的sensor,两个版本格式却不一样。一个是：
static U16 hv7131bxx_start_data[][3] = {
    {0xA0, 0x01, 0x0000},
    {0xA0, 0x10, 0x0002},
    {0xA0, 0x00, 0x0010},
    {0xA0, 0x01, 0x0001},
    {0xA0, 0x77, 0x0101},
    {0xA0, 0x03, 0x0008},        //00
    {0xA0, 0x03, 0x0012},
    {0xA0, 0x01, 0x0012},
    {0xA0, 0x02, 0x0003},
    {0xA0, 0x80, 0x0004},
    {0xA0, 0x01, 0x0005},
    {0xA0, 0xE0, 0x0006},
    {0xA0, 0x00, 0x0098},
    {0xA0, 0x00, 0x009A},
    {0xA0, 0x00, 0x011A},
    {0xA0, 0x00, 0x011C},
    {0xA0, 0x30, 0x0092},
    {0xA0, 0x2D, 0x0093},
    {0xA0, 0x00, 0x0094},
    {0xA0, 0x01, 0x0090},
   .........
};
一种是
__u8 HV7131B_Initial[]={
        0x00,0x00,0x01,0xcc,0x00,0x02,0x00,0xcc,0x00,0x10,0x00,0xcc,0x00,0x01,0x01,0xcc,0x01,0x01,0x77,0xcc,
        0x00,0x08,0x03,0xcc,0x00,0x12,0x03,0xcc,0x00,0x12,0x01,0xcc,0x00,0x03,0x02,0xcc,0x00,0x04,0x80,0xcc,
        0x00,0x05,0x01,0xcc,0x00,0x06,0xe0,0xcc,0x00,0x98,0x00,0xcc,0x00,0x9a,0x00,0xcc,0x01,0x1a,0x00,0xcc,
        0x01,0x1c,0x00,0xcc,0x00,0x30,0x2d,0xaa,0x00,0x01,0x05,0xaa,0x00,0x02,0x80,0xaa,0x00,0x11,0x00,0xaa,
        0x00,0x13,0x00,0xaa,0x00,0x14,0x01,0xaa,0x00,0x15,0xe6,0xaa,0x00,0x16,0x02,0xaa,0x00,0x17,0x86,0xaa,
        0x00,0x31,0x38,0xaa,0x00,0x32,0x38,0xaa,0x00,0x33,0x38,0xaa,0x00,0x5b,0x01,0xaa,0x00,0x19,0x00,0xcc,
        0x00,0x12,0x05,0xcc,0x01,0x00,0x0d,0xcc,0x01,0x8d,0x70,0xcc,0x01,0xa8,0x60,0xcc,0x01,0x9b,0xc0,0xcc,
        0x01,0x9c,0xa0,0xcc,0x01,0x88,0x02,0xcc,0x01,0x89,0x06,0xcc,0x01,0xc5,0x03,0xcc,0x01,0xcb,0x13,0xcc,
        0x02,0x50,0x08,0xcc,0x03,0x01,0x08,0xcc
};



都是HV7131  CMOS图像传感器的初始化。谁能给解释一下两种格式啊？谢谢！

pcshow

帮顶下。

谢谢楼上的

没用过HV7131，姑且猜一下，是否也是I2C接口。第一种格式，看上去像I2C地址+寄存器地址+寄存器值，第二种有点诡异，一排0xCC、0xAA，分隔符？等待时间？还是要看明白相关的代码

懒骨头

这两个的定义也不一样啊，会不会功能根本就不是同一回事？
static U16 hv7131bxx_start_data[][3]
__u8 HV7131B_Initial[]
从变量名称来看，一个是启动数据，一个是初始化数据，查查其对应的功能。

vitashmily

我看了一下，两个实现的功能是一样的。就是不知道什么意思。O(∩_∩)O

bravo314

有没有datasheet之类的资料供参考？

zachy

有中星微的datasheet，也有sensor的资料，呵呵，我看不懂。只好一点点的猜了

wn1983

还有个问题问大家：不知道下面这些表示什么意思？
enum {
    SensorId = 0,
    reg8d,
    val8d,
    SensorReg1,
    valSreg1L,
    valSreg1H,
    SensorReg2,
    valSreg2L,
    valSreg2H,
    totval,
};

static U8 zcxxi2cSensorSIF[1][totval] = {

{0x0f, 0x8d, 0x08, 0x03, 0xaa, 0x00, 0xff, 0xff, 0xff},
}；

这些是linux下面摄像头的驱动。
zcxxi2cSensorSIF的意思是传感器的分辨率？那里面的值0x0f, 0x8d。。。又是什么那？
实在不明白。

在zc3xx.h里有
enum {
    SensorId = 0,
    reg8d,
    val8d,
    SensorReg1,
    valSreg1L,

};

    {0x8b, 0xb3, 0x11, 0x12, 0xff},        // HV7131R

    {0, 0, 0, 0, 0}

里面的值指的是cmos sensor的什么那？？？

jang2lin

请问下楼主这个弄明白了吗？

jang2lin

我想请教下HV7131怎么修改它的分辨率啊？把他设成SIF mode
