Posted on February 22, 2006 at 06:57hello to all,
it is my first post that shipment.
I have a problem with the ST9 F120, I am trying to create a software that to every data received on the serial me kinds a interrupt.
I have connected the ST9 to a hyperterminal I am through SCI1(9,1,9,0), SCI0(5,2,5,1); digit on hyperterminal the SCI0 I would want that it generated a interrupt and that me correspondent to SCI1 wrote the characters on an other hyperterminal but unfortunately this does not happen could even help me with a small code of example? I enclose you mine more soon main and rows SCI.C aspect to yours news thanks
MAIN.C
void main(void)

di();

P0C0R = 0x00;
P0DR&=0;
while(1)

INIT_SCI_IT();
ei();
spp(P0C_PG);
P0DR &= 0x0;
P0DR ^= 0x2;
spp(SCI0_PG);
ToRec=S_RXBR;
if (ToRec != temp)
{
spp(SCI1_PG);
S_TXBR=ToRec;
temp=ToRec;
}
}
spp(P0C_PG);
P0DR ^= 0x80;
