Does the spectrometer tutorial work with the 14 bit Red Pitaya board as
well? The tutorial mentions the 10 bit board, but I am using the 14 bit
board version.
Also, going through the spectrometer tutorial with the 14 bit board, I get
the following message at the terminal when executing the python command.
Can someone help me with what might be the issue here?
