Adc/dac transfer data request

rfrsoc 4*2 version 3

I have matlab complex floating point data, i can transform it into fixed form in matlab.
Since the DAC is 14-bit, need i transform my matlab data into 14 bit fixed point mannually before sent it to DAC, or can DAC change it or using PS on the board?

Another thing is when using package:
-from rfsoc_radio.overlay import RadioOverlay
-ol = RadioOverlay(run_test=True, debug_test=False)
This package seems to limit the transfer between DAC and ADC in unsigned interger.

Hi,
You want to send floating points from the DAC of the board to an ADC of the same or of another board. Am I correct?
Before trying to answer your questions, how do you plan to send your data from the PS to the DAC, that is in the PL?

Maybe this request could interest you:

Yes, you understand it correct.
I copy the data file to ps jupyter folder, and plan to use this package rfsoc_radio. ol.radio_transmitter.data(mydata)
But it is highly possible that this package cannot fix my data requirement.

I will see you link.
