Getting a Kernel panic when trying to use it with EzTime library #3

I have traced these panics to using a timer or ISR and doing too much inside it. Post anything different if you see it

Will try out your changes on the Matrix panel when I get a change

I do not know the underlying cause but I was able to circumvent the problem by copying core_esp_main.cpp from C:\Users\\AppData\Local\arduino15\packages\esp8266\hardware\esp8266\2.5.2\cores\esp8266 into the sketch directory then commenting out the 'panic()' on line 103 of the copied file.

Yeah its strange because it is specifically calling panic exception because of the 'in interrupt' check, not sure what the other 2 checks are. Its odd

afaik , this is not in an interrupt

Someone has a workaround for this on the WiFi Tetris clock repo

Worked for me and much cleaner than the core_esp_main.cpp hack I posted above

tablatronix commented 5 years ago

That is what I did also, but it did still wdt now and then during long draws, but it is probably the easiest fix. Of course you can just not use a timer or use a timer library that just uses timekeeping and a process()

tablatronix commented 5 years ago

Is it possible to compile with no-exceptions build flag and bypass this also ?

aha
