ideas for troubleshooting/ debugging esp8266?
Posted: Fri Nov 17, 2017 6:26 amH, first post here 
, I have a project with the node ncu v1.0 esp8266 and I need some ideas on how to troubleshoot/ debug please.
I'm using arduino ide 1.8.2
board Nodemcu 1.0
board manager url: http://arduino.esp8266.com/stable/packa ... index.json
The circuit has a single sensor and my code to detect sensor change is written in an interupt. Time interval between interupts is recorded and sent to thingspeak.
The issue is that although the functionality is sound, after a day or two, The serial monitor stops reporting intervals, this is reflected in the thingspeak channel. The sensor has an oboard led which indicate changes are still being detected. No errors are seen on the serial monitor. Pressing the reset button gets it going again, for a day or two then it silently fails again.
I've tried lookin at FreeHeap which is fine, and Serial.printf to see where it stops without any solid info as to what's going in.
\here's a portion of mr code with the interupt routine and setup
