Interrupts and ARM7Posted by Nobody/Anonymous on January 19, 2006 Hi, I am using the STR71x port, and want to add some interrupts. But is it neccesary to call SAVECONTEXT and RESTORECONTEXT, if the the interrupt only copies data from a perriheal to a buffer? Best regards, Frank Andersen RE: Interrupts and ARM7Posted by Nobody/Anonymous on January 19, 2006 It is only necessary if the interrupt can cause a context switch. If you are just copying data to a buffer then it is not necessary. If you are wanting the ISR to return to a different task than that that was interrupted (by calling portEND_SWITCHING_ISR()) then it is necessary.
