We need a testing code for CN0349 in Arduino or Raspberry PI..?
The CN0349 by default uses an SDP-CB controller board with an adapter, and custom software that is Windows only. I'll see if the source is available (sometimes it is.)
We do not have any code that will run directly on Raspberry Pi / Linux or Arduino. but there is a Linux driver for the AD5934 that should get you started:
And a relevant EngineerZone thread:
For Arduino, you could start with the no-OS driver:
