Any example with CAN? What library to use etc.

On which pin is the 12-bit DAC? Is there a small code example for the DAC?

[mkoch44]

The DAC is on pin A0.

[mkoch44]

1. Which options are possible for the analogReference() function, and to which pins must an external reference voltage be connected?
   The default configuration does obviously use the 3.3V supply as reference, and there is a lot of noise in the ADC measurements.
2. Obviously the DAC does also use 3.3V as reference by default. Is it possible to use another internal or external reference for the DAC?

[mkoch44]

It's disappointing that there is so much noise in the ADC values. The SAMD21 module works much better in the same circuit.

Is there an STL file for this board? (Maybe any other board has the same dimensions? )
