    I think this page just needs to be removed (it’s not used anywhere, and is duplicated on the next page).
    

    https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/cn0511/libad9166-iio_installations
    

     
    

    This page:
    

    https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/cn0511
    

     
    

    includes:
    

    Once the next version of Analog Devices Kuiper Linux gets released (2021_R2), these steps will be removed.
    

    (I think that has happened now?) What’s the update?
    

     
    

    The Python uses register reads/writes to access temperature?
    

    https://github.com/analogdevicesinc/pyadi-iio/blob/master/adi/ad9166.py#L92-L108
    

     
    

    I don’t understand that at all – since the driver exposes that as an IIO attribute.
    

    https://wiki.analog.com/resources/tools-software/linux-drivers/iio-pll/ad9162#read_temperature
    

     
    

     
    

    and NCO:
    

                   https://github.com/analogdevicesinc/pyadi-iio/blob/master/adi/ad9166.py#L125-L134
    

                   https://github.com/analogdevicesinc/pyadi-iio/blob/master/adi/ad9166.py#L136-L145
    

     
    

    which is also supported by the driver:
    

    https://wiki.analog.com/resources/tools-software/linux-drivers/iio-pll/ad9162#change_nco_frequency
    

     
    

    same for the FIR85 – implemented with reg read/write:
    

    https://github.com/analogdevicesinc/pyadi-iio/blob/master/adi/ad9166.py#L146-L166
    

     
    

    but also in the driver:
    

    https://wiki.analog.com/resources/tools-software/linux-drivers/iio-pll/ad9162#enable_fir85_filter1
    

     
    

    Is there something wrong with the driver that we shouldn’t be using it?

      Hi Robin,
      

      Sorry for the delay in getting back to you. We are also checking in on another issue with libad9166 and will update the doc once they are resolved. As for now, when we had a fresh setup done, the libad9166-iio installations need to be done.
      

      For the pyadi-IIO class, this is now currently being revised removing the direct register access. As stated by the initial developer of the class, this was done since the AD9166 driver released at the time had not yet exposed the attributes.
      

      Best Regards,
      

      Nikko
