The display is connected to a Arduino Nano Every by i2c.
Qwiic Alphanumeric display version 2.2.5 is installed in the Arduino IDE.
When running Example_01_PrintString all segments on all 4 displays gets turned on. Not what I expected.
But, when I run the Example_02_TurnOnOneSegment it works as expected.
It seems like the board communicates somehow. Calls like display.illuminateSegment(‘A’, 0); works but display.print(“Milk”); does not.
What have I missed here?
The display board is marked v10
Are there any other sensors on the bus? Share a photo of the wiring/set-up
No, it’s plain simple.

This might be a hint: In the PrintString example the first row causes an compilation error:

Removing the first line ( language:c, not present in the other examples) it compiles.

This is an issue I am having too.
I have an Arduino Nano Every connected to a Qwiic OpenLog and a Qwiic alphanumeric display.
It seems to me like the SparkFun libraries are not 100% compatible with the Arduino Nano Every (megaAVR).
When compiling the code, the compiler throws a number of messages:

Googling these messages suggests that there’s some ambiguity in which function the compiler is supposed to call.
