AGL radio on i2c

Fixed

Description

Hi ,
I would like to add i2c interface for the radio support using TEA5767 ARduino board, Currently USB RT module is supported on
AGL-Raspberry pi. Is there any reference already to add EA5767 module as Radio AM/FM to the raspberry pi b3-AGL ?  Or is there any challenges to add this i2c feature in agl ?

Environment

None

Hi Scott,

Thanks for the responses, I am in process of changing the code. I would like to know which GPS module is supported for working with RPi3-agl, Since I want to purchase it. 

 

We have tuner driver for tea5764, looks like will this suffice our requirements. 

 

Regards

Mani

I'd recommend staying away from driving the i2c device directly via the device node or using WiringPi.  As I mentioned previously, there is a V4L2 tuner driver for the TEA5767 in the kernel that could be enabled, then you could use the V4L2 API with its ioctls against the resulting V4L2 device node.  See:

https://linuxtv.org/downloads/v4l-dvb-apis/uapi/v4l/v4l2.html

for some documentation on that API.  Note that's possible that you may need to add a udev rule to make sure the permissions get set for V4L2 devices.
