CON1 LineIN & FMIN

Hello,

Is there more details on how to use the LineIN and FMIN input pins ?
What are the voltage range for analog signal for this input ?
Is there a schematics that shows a connection ?

Regards,
Martin

I can give you the schematics connection, but I also don't know much about the hardware. I will check it with the hardware engineer. QQ截图20140505101604.png

And you can also see the PIN definition here

Ok, thanks for the info.
Is there a driver to read from analog inputs?
How do I read these inputs with raspbian?

I don't know much about the analog driver. But you can refer to sunxi.org for more driver information.

hey Tony,
I heard the raspbian for banana pi v2.0 has support for these analog inputs.
Can you post information on how to configure them and read the analog input values?

We are testing the ov5640 camera, but we don't use the LINEINR and LINEINL connection. We use the driver from the linux-sunxi kernel to test the camera.

Could you please upload the image of the sunxi kernel you are using so I can test the analog inputs?

I guess if I will update the kernel tarball. You can replaced by yourself
