SOLVED Camera menu appears on VEYE-MIPI-IMX327S

Dan_LionKing

Hello.

Already on two copies of the camera VEYE-MIPI-IMX327S, a menu appears:

The menu cursor moves spontaneously...

What it is?

How do I prevent the menu from appearing?

Hi,
The data on the I2C bus causes a false trigger.
I guess you use Raspberry Pi and an MIPI DSI-2 screen， right？

Please refer to this.

We do not use MIPI DSI-2 screen. The camera is connected to Raspberry Pi 4 and Raspberry Zero.

The menu appears randomly

After sending the command:
./i2c_write $I2C_DEV $I2C_ADDR 0x07 0xFF

Camera OSD will be removed?
Will camera control by i2c be restored after turning the camera power on and off?

@dan_lionking said in Camera menu appears on VEYE-MIPI-IMX327S:

./i2c_write $I2C_DEV $I2C_ADDR 0x07 0xFF

This command will disable the access function to the isp module. This step can be executed after the veye_mipi_i2c.sh operation. It should then solve your problem.

Will camera control by i2c be restored after turning the camera power on and off?

Yes

What commands must be sent to the camera manually for this menu to appear?

@dan_lionking
Sorry, the opening of this menu is not a normal operation and the related commands are not available to customers.
We provide scripts that perform similar functions as menu.

@veye_xumm

Ok. We need to control the parameters of the camera. We cannot disable the management interface. There are no wires in the system for using another interface.

What commands must be sent to the camera manually for this menu to disappear?

@dan_lionking
Please try this:
Add the bellowing line to the end of veye_mipi_i2c.sh

./i2c_write $I2C_DEV $I2C_ADDR  0x07 0xFF&> /dev/null;

I think this will solve your problem.

@dan_lionking This question has been asked for a long time and the status has not been updated. I will mark the status as solved, so you can follow up again if needed, or just open the question.

Hello.

./i2c_write $I2C_DEV $I2C_ADDR  0x07 0xFF&> /dev/null;

disables the camera i2c interface, but does not remove the menu. We fixed the software, but after turning on the camera, the menu still appears in the picture. At the same time, the picture from the camera turned over. Turning off the power of the camera does not correct the situation...

We need a command that will remove the menu from the image...

Do You have my email address...

@dan_lionking
In the i2c_tools directory, the following command can be executed to close the menu.

./i2c_write 10 0x3b 0x0010 0xDE  
./i2c_write 10 0x3b 0x0011 0x0B  
./i2c_write 10 0x3b 0x0012 0x02 
./i2c_write 10 0x3b 0x0013 0x00

The CSI-2 DSI-2 of Raspberry Pi and the I2C of HAT board are connected together, do you use HAT board?

Since the Raspberry Pi's MIPI CSI-2 i2c is connected to the DSI and HAT interface (40pin 27 28). The GPU side will have access to the device. And our camera is accessed through the CPU side. There will be problems with concurrency causing errors.
We suggest you to refer to this article.

@veye_xumm

Thanks, let's check the commands.

Our system does not use the DSI interface.

@dan_lionking

Sequential execution of commands causes the on-screen display to disappear.

Thanks.
