Timer Obj crashes my program
SiCC
Posts: 21
Trying to figure out why the TImer Obj would cause wierd issues in my program. My program uses getStr to receive a message from my GPS every 100ms, then continues to execute the Main loop below. The PUB LapTimer below captures IR and manipulates the TIMER. I have narrowed it down to:
When I call getStr from FullDuplexSerial and any ref to the Timer Obj. I can use either successfully, but when I try to have them both working at the same time my program goes whacky.
Example, I can comment out the getStr line (first line of main loop) OR I can comment out the references to TIM in the LapTimer function. But if both are included the program dies.
Any help is appreciated!

I suspect memory corruption, then again you may have (additionally) run out of cogs.Also, your usage of Str12 is questionable. You want to refer to it as @Str12. With that out of the way what is the expected length of the string returned by the getStr method call (you only have two words reserved, i.e. 4 bytes)?
