Ok I am using a PIC16F877A and a Parallax RFID Reader Module 2814
parallax.com/Portals/0/Downloads/docs/prod/audiovis/RFID-Reader-v1.2.pdf
I am just trying to read the ID and then output it.
| Code: | #include <protoalone.h>
#include <utility.c>
#include <stdlib.h>
#include <input.c>
#use rs232 (baud=2400, parity=N, bits=8, stop=1, xmit=PIN_C3, rcv=PIN_C2, stream=RFID)
#use rs232 (baud=9600, xmit=PIN_C6, rcv=PIN_C7, stream=COMP)
#define RFID_ON PIN_C1
void main() {
char string_a[20]="no ID";
fprintf(COMP,"\r\n%s",string_a);
output_low (RFID_ON);
gfgets(string_a,RFID);
output_high (RFID_ON);
fprintf(COMP,"\r\n%s",string_a);
} |

Where is the code for gfgets()?
What is your question? |

You didn't show your #fuses statement. It might have problems.
But at a minimum, you need to add a while(1); statement at the end
of main(). The compiler puts a hidden sleep instruction there. Without
that statement, you will miss the last two characters of your ID value. |

Sorry that is suppose to be fgets() typo when posting here
Why is it not working i think it has some thing to do with fgets() or the #use rs232 for the rfid |
