Hi William,

the way I normally do this is using the array from jarray:

```
from jarray import array
pvs[0].setValue(array(yourlist, 'd'))
```

On the example, your list would be the variable yourlist.

Cheers

Hi,

I have a short question:

I have a small embedded python script that generates a waveform of 4096 points from a user-given formula. (i.e. sin(t))

I want to write that waveform data to the corresponding PV.

But phoebus / Jython complains about not being able to write a pyList Datatype ...

Caused by: java.lang.Exception: Cannot handle type org.python.core.PyList

How can I convert my python list object to a DoubleArray?

I tried to import VDoubleArray but its abstract ...

Thanks,
