I bought three Nano Every's from the Arduino store. I foolishly assumed that my existing Nano code would run on it. OK, I can see that, since it is a different processor, has more memory. But some of the things should be the same.
The most curious one is the extra CR\LF. In order to debug, I print out single characters to indicate the state of various routines. [ Serial.print('x'); ] I have a 40 second delay [unsigned long i= millis();while(millis()-i<40000); ]to simulate the unit powering down. When the delay is complete, I print [ Serial.println("Awake"); ] I get a blank line where there should be none.
Here's the really curious thing: Only on two of the Nano Every's, the other is as expected, as it is on the other five Nano's I'm running.
I have carefully looked at my code and I have only 1 println() and no \r\n's in all the statements that are executed in loop().
This is disturbing because it makes me think that there are other quirks in the Every.
