Hello to everybody!

I'm posting here to ask a question about interruptions.
I made a program in Ride with the Assembly language.
This program has an interruption with Timer0 that is called every 1 second.

My question is:
How can I make interruptions in C language?
Could anyone help me please?
I'm using the 8951.
Thanks a lot!!!
Bye!

Hello,

everything is written in RC51 documentation. To make an interrupt routine, declare a void(void) function and use the specific keyword 'interrupt'. Example :

void Timer0_Routine(void) interrupt 2
{
}

I don't know the interrupt number of Timer 0 on your device, so I've put 2 as an example. This number will be used to calculate the interrupt vector address where to locate the interrupt routine.

Lionel
