Having a RS485 and RS232 port on a PIC18F1320

[Maverick72]

Hi,

I'm trying to setup two serial ports on my chip. I already use the PIC USART module, but can't seem to be able to use the

#use rs232(baud=9600,xmit=PIN_DALLAS_TX,rcv=PIN_DALLAS_RX,stream=DALLAS)

Command to implement my other port. Could you please help me.

P.S. Here's my serial interupt routine.

#int_RDA
void UART_RX(void)
{
int i=0;
int timer_usart_rx=0;

if (kbhit(RS_485))
{

/* Boucle pendant 20msec ou jusqu'à ce que le buffer soit plein */
while(timer_usart_rx <= MAX_USART_TIMER && i <= RS485_BUFFER_SIZE)
{
if(kbhit(RS_485))
{
rs_485_buffer[i]=getc(RS_485);
i++;
}
delay_ms(1);
timer_usart_rx++;
}

bit_set(flag1,RS_485_RX_FLAG);
}

}
