hello everyone,
how to write an interrupt service routine in c++
i have following class:
class nm { public: char i; };
& ISR is:
void timer_isr(void) interrupt 1 { nm.i = 10; }
if i write in this manner then i is not accessible as timer_isr is not a function of class nm
in c we dont declare interrupt function
shall i declare here? if yes then how?
pls guide me on this
thank you all take care
There is no "general" answer - such things are always specific to the particular compiler!
If there was a "general" answer, then you would find it in the language spec and general textbooks!
For some general books, see: http://www.keil.com/books
"i'm using ceibo embedded developer"
Then you need to direct your questions to Ceibo!
"in that i m writing code in c++"
Any particular reason why? 'C' is still by far the more common for small embedded development; especially for 8-bitters!
"in c we dont declare interrupt function"
Again, 'C' has nothing to do with it; the standard 'C' language knows nothing at all about interrupts - therefore, how you do this is entirely dependent on the specific compiler that you are using.
I know if at least one compiler where you do have to declare interrupt functions!
