I am using a Yocto-based embedded Linux platform, and we would like to interface to the AD7994. I've downloaded the drivers available from ADI, but I am still unable to access the ADC. I'd rather not publish my code on this public forum. Is there someone who could support us directly?
Unfortunately this is the only place where we can offer support for the Linux drivers.
Did you register the ADC I2C devices as well as the regulator providing VREF as described in the Documentation for the AD7994 Linux driver? If yes, is the device registered? Does it show up in /sys/bus/iio/devices/?
