global variable not getting updated in interupt service routine #18

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I was trying to increment a global variable inside an interrupt service routine 
but i found after returning from interrupt service routine the global variable 
was restored to previous value .
I tried declaring the global variable as volatile but it is not giving any 
effect.

I am using code sourcery tool chain for compiling the code.
