| Simple question about 16F628 RS232 |

I try to use other pins other than B1 and B2 to do RS232 but the data i m receiving is not correct. Izzit possible to use other pins to do RS232 or is there anything i should do to make it possible?
I have declared it correctly.
Thank you. |

You can use any I/O pins that are free. You have not given any clue as to what your problem is. Without a crystal ball there is nothing else I can suggest.

What pins are you using ?
Try this simple program with a terminal program running on your PC.
This program just returns the same character that was sent to it.
Substitute your pins for B2 and B1. See if it works.
If it doesn't work, then post your version of the compiler.
| Code: | #include <16F628.H>
#fuses XT, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 4000000)
#use rs232(baud=9600, xmit=PIN_B2, rcv=PIN_B1, ERRORS)
//======================================
void main()
{
char c;
while(1)
{
c = getc();
putc(c);
}
} |
