ADC inputs on Duet or Duex?
-
Does the Duet or Duex have any ADC inputs? I want to experiment with a sensor that outputs an analog 0-5V voltage.
Any thermistor pin should work right? Are there any non-thermistor pins that will work as an ADC input? I don't mind if I have to add a few lines to the firmware to make it work.

Yes any thermistor pin should work, however they all have an RC filter between them and the processor, so you can't use them to measure rapid changes in voltage. To see whether there are any other expansion pins you could use, see https://duet3d.dozuki.com/Wiki/Duet_2_Pinout_table and the datasheet for the ATSAM4E8E-AU chip.
