PIC16F874 max232n ne ce da vrati informaciju?Kada ja tipkam sa tastature podaci se prikazuju na lcd koji prikljucne isto na pic pokazuju tacno ono sto ja otkucam ali ako ja iz pica postavim printf("g"); nece da vrati jednostavno nema nsita na hiperterminalu.
Koristim pic-c kompajler.
Evo i kod:
Code:
#include <16F874.h>
#include <stdlib.h>
#include <string.h>
//#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#include "lcd.c"
#use rs232(baud=115200, xmit=PIN_C6, rcv=PIN_C7)
#bit RCBUFF_FULL=0x0B.4
int j=0;
#INT_RDA
rs232(){
int a;
a=getc();
j++;
lcd_gotoxy(0,1);
printf(lcd_putc,"%d",a);
lcd_gotoxy(0,7);
printf(lcd_putc,"%d",j);
}
void main(){
lcd_init();
enable_interrupts(GLOBAL);
enable_interrupts(INT_RDA);
printf("GED");
putc('F');
while(true) {
while (!RCBUFF_FULL);
}
petlja: goto petlja;
}
#include <16F874.h>
#include <stdlib.h>
#include <string.h>
//#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#include "lcd.c"
#use rs232(baud=115200, xmit=PIN_C6, rcv=PIN_C7)
#bit RCBUFF_FULL=0x0B.4
int j=0;
#INT_RDA
rs232(){
int a;
a=getc();
j++;
lcd_gotoxy(0,1);
printf(lcd_putc,"%d",a);
lcd_gotoxy(0,7);
printf(lcd_putc,"%d",j);
}
void main(){
lcd_init();
enable_interrupts(GLOBAL);
enable_interrupts(INT_RDA);
printf("GED");
putc('F');
while(true) {
while (!RCBUFF_FULL);
}
petlja: goto petlja;
}
