I am running into an issue with FastLED on a genuine Arduino UNO, The system locks up after running for more than 12 hours.

It seems to occur in the “Rainbow Chase” pattern.

Can anyone see what could be causing a problem?

NOTE: I tend to code in a modular fashion to allow reuse of parts in other projects.

Arduino IDE 1.8.2

pragma message “FastLED version 3.001.003”

Code: GitHub - brencerddwr/Berkana_v4: Latest revision of LED sign shaped like Berkana made with radio shack leds

Have you tried adding serial prints to catch the exact point that it locks up? Any chance you can get a more isolated set of code that exhibits the lockup - there’s a lot of paths through your code which makes it more difficult to eyeball for problems.

I will add some serial prints to the code to see if I can get an idea of when it locks.

I was hoping I was missing something obvious.

I found a library that will log the program location to the eprom on lockup and reboot. It has not shown the problem since. :unamused:
