While loop do not work or maybe ram overflow?

Thank you very much !

first check the mem usage all along the sketch, second optimize the strings.

i'll let you know the result.

Good news! I've found where the problem was :slight_smile:

It was not a memory overflow, I never go under 900 byte of free memory before optimizing. But I've learn a lot about it, and I want to thank you for this :slight_smile:
Now I got more than 1k of free mem with the complete sketch loaded.

The problem was on the 'noInterrupts()' command inside of the while loop.
I don't know why but disable the interrupt is causing the Arduino to freeze.

I'm curious if someone could tell me why is this happening :slight_smile:

Anyway, my project is complete now and working good.

Lots of things depend on interrupts happening. Like millis() getting updated. Which delay() depends on.

Disabling interrupts is rarely a good idea, unless you really know what you are doing.

So it's better now without disable it.

Thank you :slight_smile:

And another example of why, when we say "post all your code", we really mean it.

This part was in the first code I've posted :wink:

But I understand and will post everything now :smiley:
