I am working with a nRF52832 breakout board, and trying to use mills() to time a 30 minute event. Surprisingly, I looks like I'm running into some type of rollover at 512 seconds.

The following code:

Code: Select all

#include <Wire.h>
void setup()
{
Serial.begin(9600);
Wire.begin();
}
void loop() 
{ 
  Serial.println(millis())
}

GIves this every time I run. (abbreviated)

Code: Select all

Any help would be appreciated on what needs to change to avoid this.
Thanks,

matt

That code won't compile, so it isn't what you were running.

Hi,
Thanks for catching the error - missing a ;

Here is the corrected code:

Code: Select all

#include <Wire.h>
void setup()
{
Serial.begin(9600);
Wire.begin();
}
void loop() 
{ 
  Serial.println(millis());
}
