local variable inside ISR

#1 Post by jpc » 08 Feb 2011 08:46

this is just a question : can i use local variable's inside an ISR or is there a risk these will be mapped on some other local var ? This also would affect local vars used inside functions called from withing the ISR i presume. If possible have this explained well and integrated in the help on interrupts.

there is no risk for local variables and parameters, each function call has its own frame and its own instances.
