adrv9009/zcu102 iio trigger

Hi there,

I was looking at the following link:  https://wiki.analog.com/software/linux/docs/iio/iio_snippets#iio_device_files 

but noticed https://ez.analog.com/fpga/f/q-a/121342/is-there-a-way-to-use-internal-or-external-triggers-when-performing-data-capture-on-the-zcu102-using-the-adrv9009 as well.

I have a .c file running the zcu102/adrv9009 setup and i'd like to poll whether a trigger has toggled.  Is there really no trigger functionality through iio?

Best,

Michael
