Unsigned Long overflow

Recommended Posts

I hope this is the right place to ask this but I’m having a problem with unsigned long.  According to the Energia reference it should go to 4,294,967,295.  But my unsigned long value is overflowing at 65535 same as unsigned int.  I’m using it as a set point for millies based on a pot so I’m limited to about 60 seconds.  Anything over 65535 wraps back around to zero giving me a time of what it’s set to minus 60 seconds.  I’m sure there’s a work around but everything I can find says unsigned long should work.

please help,
