8051 C language

(1/1)

BEAVIS:
Hi all
I have never used C language to program a 8051, I have a few questions sorry they migth sound stupid; how do you define an interrupt vector in C? For example to define a interrupt vector in assembly for UART I say "ORG 35H", how do you do that in C? is there any predefined method like "main" which we use for "ORG 00"?
Thank you

MikeR:
What are you using to compile the code? SDCC , Micro C?

I use SDCC and it tells you how in the Manual


void sw1_isr(void) interrupt 0; // /INT0 P3_2
void sw2_isr(void) interrupt 2; // /INT0 P3_3

I am sure that if you are usin Micro C it is also explained in the manual.

I am far from an expert just did a little reading
