Zasada jest w sumie taka sama w większości ( jeśli nie we wszystkich) uC. To co masz w RM ta tablica skoków do wektorów obsługi poszczególnych przerwań. Ich nazwy w zasadzie mogą być dowolne, byle by się zgadzały z nazwami w tablicy skoków w pliku startup.s Twojego uC. Masz w nim coś takiego:[syntax=asm]/******************************************************************************
*
* The minimal vector table for a Cortex M3. Note that the proper constructs
* must be placed on this to ensure that it ends up at physical address
* 0x0000.0000.

i stąd możesz wziąć nazwy procedury obsługi przerwań. To funkcja, jak każda inna: void jakaśtamnazwa(void). Oczywiście, możesz zmodyfikować nazwy wektorów przerwań według własnego widzimisię, ważne aby te nazwy zgadzały się z tymi z pliku startup.s. Aha, __attribute__((interrupt)) możesz sobie w tej chwili darować ( korzystając ze współczesnych kompilatorów).
Pozdrawiam, QuadMan.

Code:
ISR(TIMER0_OVF_vect)
{
// jakis kod
}

Pomijam czy to od przepełnienia(jak wyzej) czy porównania itd. W przypadku stm znalazłem tylko table vector w reference manualu, natomiast w internetach wystepuje np.
Code:
__attribute__((interrupt)) void SysTick_Handler(void){
// jakis kod
}

Skąd to się bierze ? Czy zasada jest taka ze piszemy to magiczne "__attribute__((interrupt))" nastepnie do nazwy konkretnego przerwania z wspomnianej wyzej tablicy wektorów dopisujemy "_Handler" i dodatkowo całośc traktujemy jako funkcje która nic nie zwraca i nic nie przyjmuje ?
