Software Serial
PostPosted: Wed Mar 30, 2011 7:21 pm     Reply with quote
Hi
I am trying to use two serial communication in PIC16f877a -Software as well as hardware serial. Unfortunately, if I use fprintf( stream,"CCS"), then the hardware serial also wont work!
What may be the problem?
Here is my code

Code:


#include<16f877a.h>
#use delay(clock=20000000)
#USE RS232(BAUD=4800,errors,PARITY=N,XMIT=PIN_D1,RCV=PIN_D0,BITS=8,stream = CH1)
#USE RS232(BAUD=9600,errors,PARITY=N,XMIT=PIN_C6,RCV=PIN_C7,BITS=8)

void main()
{
   char ch;
   
   fprintf(ch1,"CCS");
   while(1)
   {
      delay_ms(1000);
      printf("hai");
      }
      }

Make all #use rs232() statements into streams. Use fprintf with stream
ID's for everything. Then it should work.
