If i setARefVoltage to 3.3 i get constant 1023 on analogRead, all axis. I'm using an Ardino Pro Mini 3.3 Version. Why is that happening?

Thank you, Mari

I found the same problem--commenting out the ARef line makes the code work fine. I'm using an Arduino Uno R3 .

Hey there,

As per the comments in the code

"When you want to use 3.3 AREF, put a wire between the AREF pin and the 3.3 V VCC pin. This increases accuracy."

Hope that helps.

Deleting the ARef does work. Specifically the accelero.setARefVoltage(3.3) line.
