When I flash my code Boron will turn solid white


Im trying to run a tipping bucket rain gauge, Ds18b20, and monitor the power using fuel gauge all in the same time. When I run rain gauge and temp it works fine, when I run rain gauge and fuel it works fine. When I run all three, the boron turn solid white.

Side problem- for some reason once in a blue the rain gauge will log rain but there is no rain. For example it indoor right now and it will log 2 to 5 tip, sometimes more. For days it was running fine but when I power off and on sometime it acts up again. This could be a hardware issues. Im getting new rain gauges tomorrow. But it could be code issue and im just not seeing it.

Im new to coding so im sure I did something wrong. Im hoping someone smarter then me will see the issue and help get this running properly. Here is the code. Thank you very much for your time

You can try the new official realeas 0.9.0 to see whether this changes anything.
Also what Boron are you using? (2G/3G or LTE)

With millis() timings it’s always better to use (millis() - previousEvent > eventPeriod) instead of precalculating the next trigger time and check for (triggerTime <= millis())
Reasoning behind that can be found in this thread

Any solid colour typically indicates some kind of device OS deadlock which can be caused (amongst others) by ISRs, noInterrupt() calls (possibly in any of the used libraries), concurrent use of shared resources (e.g. HW interfaces) between application and device OS.

Hey ScruffR, Thanks for your reply. I have LTE. I tried changing the millis() part but because Im new in coding I keep getting errors when I compile. Ill keep trying.

Thanks again
