Fix voltage reference in examples

[romainreignier]

The MachineControl boards features a REF3330 3.0 V Reference Voltage.

As mentioned in this #70 (comment)

I have compared the 0-10V input results with an oscilloscope and the values with the 3.3 V reference were wrong but correct with 3.0 V.

[facchinm]

The patch looks correct. @Rocketct would you mind taking some more measurement on a production board and eventually merge? Thx
