Thank you very much for your reply. I think i am confused when i am writing to the forum my code will be like this (coma and comb will reverse)
Code:
| Code: |
#include "16F877A.H"
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6,rcv=PIN_C7,stream=coma)
#use rs232(baud=9600, xmit=PIN_B2,rcv=PIN_B3,stream=comb)
void main()
{
char c;
align=0;
while(TRUE){
if(align==0){
fprintf(comb,"sending search signal");
putc('~',coma);
align=0;
}
if(kbhit(coma)){
fprintf(comb,"received something");
c=getc(coma);
if(c=='~')
{
fprintf(comb,"received search signal");
}
else {
putc(c,comb);
}
}
}

I am using isis professional also for this code and for the other code that i wrote before it gives what i want.But in real world i cant make the same thing.i also abandoned writing sending search signal received something and received search signal.I just wrote the following code
| Code: |
#include "16F877A.H"
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6,rcv=PIN_C7,stream=coma,ERRORS)
#use rs232(baud=9600, xmit=PIN_B2,rcv=PIN_B3,stream=comb)
void main()
{
char c;
align=0;
while(TRUE){
if(align==0){
putc('a',coma);
align=0;
}
if(kbhit(coma)){
c=getc(coma);
if(c=='~')
{
fprintf(comb,"received search signal");
}
else {
putc(c,comb);
}
}
} |
What i am trying to do is
I have both tx/rx in two side so nodes will send '~' or 'a' for search signal if a node gets search signal it responds back hey i got something and if he gets '~' he will say i got search signal.
I will try to send just '~' not comments at all but in future that will not help because i have to set some flags and preambles for the protocols. So if pic16f877a have hardware limitations to do this i will use another pic what you prefer me? |
