Sorry, wrong picture of camera
Correct is this

Possibly same question [url]http://ebaina.com/bbs/forum.php?mod=viewthread&tid=12802&highlight=ar0237[/url]

hello！I think the interface of the production that is not HISPI。This Possibly is DVP。

Hello!I'm doing Hi3516C+AR0237,the interface of the production that is DVP,not the same as Hi3516D.
So,I  recommend you to check the I2C communication,see if I2c work well.Then check the VI_DEV_ATTR_S struct  and then check the combo_dev_attr_t struct.
You can find the config on "Hi3516A V100R001C01SPC050\02.Only for Reference\04.other\configs_of_Hi3516A_Stream_V1.0.5.0\ar0237_1080p_line.ini".

By the way,AR0237 can use DVP and HiSpi.The Hi3516C can only use DVP , Hi3516A/D can use HiSpi. So the interface is OK,you should find the problem that I say on 5#. Good luck!

Thank you for your answers!
What is DVP? Is it BT1120?

What is the best way to check i2c communications? Can I check it by software? Or do I need to connect some external i2c device to the bus pins and listen data?

In Hi3516C is VI_MODE_DIGITAL_CAMERA.
Yes,by the software.You can write a function to write the ar0237 register via I2c,then read the register,see if you write the register sucessfully.
for example,you write register 0x3012 with the value 0x03,then you read the 0x3012 register,see the value is 0x03 or not.

By the way, do you have datasheet for ar0237 with information about i2c registers and do you have sources for ar0237 init?
I am using libsns_ar0237 from SDK, but there is only 30fps init, not 60fps and there is no DVP mode, only LVDS.

I have 3516D+AR0237 DVP interface, i think i can try it

You can contact me, QQ is 1315540389

csuzhsh, Do you have wechat or email?

Now, I have i2c init for  ar0237 in parallel mode (thanks to csuzhsh), but I still have troubles to init VI.

Here is part of my code, that inits VI, but I think there is error in VI_DEV_ATTR_S

Could somebody experienced check it.

what‘s the problem？

hello Nikita，I have the same problem with you, hi3516d+ar0237, Vi has no interrupt , Do you have wechat or email?

Hi wayen_yan! Pls check private message.

I have attached logic analyzer for i2c bus, record original negotiation and write my own func for libsns_ar0237

    printf("Aptina AR0237 sensor linear PARALLEL 2M-1080p 30fps init success!\n");
   
    return ;
}[/code]

But with this code fps is a bit unstable, for example for 30fps, I have sometimes 32ms between frames.
For IMX178 and hi3516a I have stable time between frames.

Hi cathy82008!
Pls check my message from 2016-10-14 17:58:13 in this thread.
You have to change source of  libsns_ar0237, replace sensor_linear_1080p30_init() function code.
I have used XM camera module, that I have bought on HuaQiangBei security market.
