CN0511 code issue

Rgetz

on Apr 21, 2023

Category: Software

Product Number: CN0511

Software Version: Git master

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?

Biao.H this is probably better handled by the CFTL team since its related to the RPI hat. who is maintaining the library here?

It's been 2 weeks and no answer - is this hardware/software not supported?

I agree that the first page is a duplicate of information already available in the cn0511 page. It is no longer referred to in the user guide.

There is nothing wrong with the driver. I'll check with the developer of the pyADI-IIO class and have the changes done. It is possible that the class was done when the driver has not yet exposed the attributes.

Best Regards,

Nikko

That's easy to check with gitblame.

https://github.com/analogdevicesinc/linux/commit/f6833d5f5c3dcecbad3e117595442858c0907b0d

AD9166 was added to the Linux driver : Jan 23, 2020

https://github.com/analogdevicesinc/pyadi-iio/commit/048aa23ac516e4fc3da0a795fd8d94eeffe68201

The python pieces were added 2 years, 5 months, 21 days after the Linux driver was done (Jul 14, 2022).

> I'll check with the developer of the pyADI-IIO class and have the changes done.

Any ETA on that?

It's been another 10 days, with no answer. Nearly a month since I asked by original question.

The doc questions still stand.

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

is not linked from anywhere? do I need to do those, or not?

Looks like Erbe removed the weird instructions (thanks) on the main page.

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
