Hello everyone
I just would like to read a sine wave by (ADC of ) teensy 3.2, then I would like to send this signal to the DAC of teensy and see it on the oscilloscope.
in other word, the same signal is entered to teensy I want to see it as an output of the teensy. To do so, I think I have to match reference voltage of both DAC and ADC and the sampling rate of ADC with Conversion speed of DAC.

my question is:
Is that possible to do? If yes, please tell me how!

THanks in advance.
