tx_two object has no setter

[rookiebeotch]

i have ver 0.18.
when i run:
sdr = adi.adrv9002(uri="local:")
i get this error:

Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/local/lib/python3.11/dist-packages/adi/adrv9002.py", line 75, in _ _init__ self._tx2 = tx_two(self._ctx, self._txdac2, self._tx2_channel_names) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/dist-packages/adi/obs.py", line 59, in __init __ self._complex_data = complex_data ^^^^^^^^^^^^^^^^^^ AttributeError: property '_complex_data' of 'tx_two' object has no setter

my device (adrv9002) has both channels enabled and split.

Try the current commit from the main branch. I believe this was fixed by this commit awhile back a40cafb

I verified the current branch does fix the original issue, but there are several others in the example file which seem to have not been updated. Also, the repo could use a new release tag since there haven't been any in years and many issues have been fixed.

Release was created this morning.

Can you expand on what you mean by examples not being updated? The referenced example works just fine.

The AGC settings are no longer valid. Also I get an error on the gain values.

ah ok yeah the digital_gain_control_mode_chan0 I think are only automatic and SPI now but need to look at the test code. In regards to the interface gains, these are specific to the part configuration. There is a way to see the valid ones based on the current part state like so:

dev = adi.adrv9002()
chan = dev._ctrl.find_channel('voltage0', 'interface_gain_available', False)
print(chan.value)

Thanks for suggestion. The code above didn't quite work. It gave the following error:

Traceback (most recent call last):
  File "C:\Program Files (x86)\JetBrains\PyCharm Community Edition 2024.1.3\plugins\python-ce\helpers\pydev\_pydevd_bundle\pydevd_exec2.py", line 3, in Exec
    exec(exp, global_vars, local_vars)
  File "<input>", line 1, in <module>
TypeError: find_channel() takes from 2 to 3 positional arguments but 4 were given

I ended up setting the control mode to "spi" and using this to find an acceptable gain:

test=sdr._ctrl.find_channel('voltage0')
test.attrs["interface_gain_available"].value
'0dB'

Then everything after that worked.
