ISR vector

HI everyone !!

i'm using the st72264 chip with the metrowerks compiler and i did not manage to associate my interrupt routine to the ISR vector.

i found an example that uses the ISR vector :

void (* const _vectab[]) () = {

NULL,

SCI_Interrupt,

NULL,

PORTS_1_Interrupt,

PORTS_0_Interrupt,

NULL,

};

but i keep getting a compilation error :

'implicit cast in assignment'

what is wrong ?

can anyone help me ? can someone give an example how it should be done ? (in 'c' please)

thanks.

adi.

The examples you give is for the cosmic compiler, for metroweks you need to modify the prm file for the project.

Look up the VECTOR keyword in the linker docs.

Here is an example of a F264 PRM file:

***************************

NAMES

END

SECTIONS

MY_RAM = READ_WRITE 0x0080 TO 0x00FF;

MY_ROM = READ_ONLY 0xE000 TO 0xFFDF;

PLACEMENT

DEFAULT_ROM, ROM_VAR, STRINGS INTO MY_ROM;

_ZEROPAGE, _OVERLAP, DEFAULT_RAM INTO MY_RAM;

END

STACKTOP 0x17F

VECTOR ADDRESS 0xFFFE _Startup

***************************

regards,

Piero

thanks for the feed back,

the PRM file is as piero's example

but i still need your help as for how to assign the functions,

i must admit it's my first project using the ST.

thanks again.
