… Let me know if you need any other information or have any suggestions.Thank you.
Yes, what is the problem?
If it doesn’t work, give the symptoms that indicate to you that it is not working. Have you measured the voltages at the output?
Why is the CLR pin connected to GND? What does the datasheet (and comments in the example code) say about it’s function?
Also, the unaltered Arduino sketch, library files, and datasheet for the DAC "attached below’’ didn’t come through in your post. There are links at the top, but not sure if that is what you meant.
