I'm using 16F877A and I'm blocked in how to copy an entered value from a keyboard to an array already declared empty. But it won't work because in debugging mode the array is always taking the value ' ' (space). I've tried everything but nothing... a little help please!!!
| Code: |
#include "16F877A.h"
#use delay(clock=10M)
#byte PORTB= 0x06
#byte PORTC= 0x07
#byte TRISB= 0x86
#byte TRISC= 0x87
#byte PORTD= 0x08
#byte TRISD= 0x88
#bit E =PORTC.0
#bit RS=PORTC.1
#bit C1=PORTD.0
#bit C2=PORTD.1
#bit C3=PORTD.2
char texte[28]="veuillez saisir le code ";
char Tvrep[13]="code correct";
char Tfrep[15]="code incorrect";
int i;
char touche=' ';
void envoie_commande(char commande)
{
E=0;
RS=0;//mode commande
PORTB=commande;
E=1;
delay_us(50);
E=0;
}
void envoie_caractere(char caractere)
{
E=0;
RS=1;//mode affichage
PORTB=caractere;
E=1;
delay_us(50);
E=0;
}
#int_timer0
void clavier()
{

You are not declaring an array.
Single inverted commas, declare a single character.
Declare your array, as:
char touche[5];
Make it large enough to store the charcters you want, _and_ remember the space for the terminating '\0', if you want to use it as a string. Add the characters to this, and remember to add the termination.
Best Wishes |
