| RDA Interrupt not working |
 Posted: Tue Apr 18, 2006 12:42 pm |

I am using 18lf8722 and are using both uarts. Here is the RS232 Line in my code
#use rs232(baud=2400,xmit=PIN_c7,bits=8,parity=n,rcv=PIN_c6,ERRORS,STREAM=USB) //,disable_ints) //USB CHECKED OK, could not get RDA to work
#use rs232(baud=2400,xmit=PIN_g1,rcv=PIN_g2,RESTART_WDT,parity=n,bits=8,ERRORS,STREAM=RS232) //,disable_ints) //works with RS232
I enabled the RDA Interrupt. But it does not work.. Any Ideas?  |

You have to use the correct pins and you have to use the correct
statement to invoke the RDA interrupt for the 2nd serial port.
Example:
| Code: |
#include <18F8722.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock=4000000)
#use rs232(baud=2400,xmit=PIN_C6, rcv=PIN_C7, ERRORS, STREAM=USB)
#use rs232(baud=2400,xmit=PIN_G1,rcv=PIN_G2,RESTART_WDT, ERRORS,STREAM=RS232)
#int_rda
void rda_isr()
{
char c;
c = fgetc(USB);
}
//------------------
#int_rda2
void rda2_isr()
{
char c;
c = fgetc(RS232);
}
//=======================
void main()
{
while(1);
} |
