Internal reference set to 0, and getting the message dac busy, crc alarm, temperature alarm

[jpnath93]

Used your example code, so not attaching the code here, we modified only two lines

dac.set_out(1, 0x00FF); delay(10000);

and

// Set range, U = Unipolar, B = Bipolar; 5, 10, 20, 40, 2V5
  dac.set_range(1, DAC81416::U_10);

Howevre the range of channel 1 is 0 and no output is seen when measruing channel 1 using multimeter

here is the serial monitor output:

  2154
DAC Init...
DAC is alive
DAC is device id 2154
DAC Temperature = -915.00*C

Hey

I'm not sat in front of any of this right now as I'm travelling, but I recommend to check the wiring. Also check CRC is disabled on the DAC.

Also check CRC is disabled on the DAC.

How to do this?
