[Solved]Serial Interrupt isn't working
PostPosted: Thu Sep 05, 2013 3:42 pm     Reply with quote
I must be doing something very stupid as I can echo characters using a polled routine (tx & rx using realterm)

Code:
#include "18f87k22.h"
#fuses HSH ,PLLEN, NOWDT, NOPROTECT   // , NOLVP
#use delay(clock=58982400)
//#use rs232 (baud=19200, xmit=PIN_C6, rcv=PIN_C7, PARITY=N, BITS=8)
#use rs232 (baud=19200, xmit=PIN_G1, rcv=PIN_G2, PARITY=N, BITS=8)

void main()
{
   do {
        putc( getc() );
   } while (TRUE); // END OF MAIN LOOP
}


but when I try to use #int_rda

Code:
#include "18f87k22.h"
#fuses HSH ,PLLEN, NOWDT, NOPROTECT   // , NOLVP
#use delay(clock=58982400)
//#use rs232 (baud=19200, xmit=PIN_C6, rcv=PIN_C7, PARITY=N, BITS=8)
#use rs232 (baud=19200, xmit=PIN_G1, rcv=PIN_G2, PARITY=N, BITS=8)

#int_rda
void serial_isr() {
   putc( getc() );
}

void main()
{
   enable_interrupts(INT_RDA);
   enable_interrupts(GLOBAL);
   do {
      delay_ms(10000);
   } while (TRUE); // END OF MAIN LOOP
}


it doesn't work. What am I missing?

Thanks all.

Duncan

Thanks PCM programmer. You are quite correct.

I was having problems with the polled version on C6, C7 as well but that must be hardware.

Thanks again for your rapid help.
