For some unknown purpose? No.

The purpsose is on the project section where we realise that FlexiTimer2 may damage the program with its interupt.

Well, that's clear as mud.

I just know (99%) that i have problem with the library, didnt want to repost the whole code and fire you with question. That's why i posted only about the library.

As i said in project section its for my project and after people saw my code and discuss it we end that library/interupt may damage the program.
