| getch() |

in the main program where the getch() function is called, the program gets into trouble. i ve just used the example code ex_stwt.c and the simplest example ex_sqw but i couldnt make them work. and i couldnt use getch() with hyperterminal. ive tried using kbhit() option but it also didnt work. pic sends data but just a simple echo thing cannot be done.
while (true)
{
putc( getc() +1);
}
what should be done? |

First, why are you adding 1.
Second, post a complete small test program. |

You say it doesn't work, but you don't tell us what it doesn't do. The code you show should run but we don't know what you are expecting.

| Code: |
#include <16F877.h>
#fuses XT,NOWDT,NOPROTECT,NOLVP
#use delay(clock=4000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, errors,BRGH1OK)
void main()
{
while(TRUE)
{
printf("start");
putc( getch()+1 );
}
}
|
when you write 'A' computer prints 'B'. this the 'not working small program' .
start is seen but no action on the receive pin. serial port works properly verified by the loopback. |
