Hi,
Yes you can change the attributes dynamically. The driver will update the
registers as soon as you write the new value. But in case of the FMCOMMS1
board you should modify the sampling frequency of the DAC by writing to the
"out_altvoltage_1A_sampling_frequency" attribute of the "cf-ad9122-core-lpc"
device.
