a function for get a value with decimal using a keyboard4*4
PostPosted: Mon May 28, 2007 7:46 am     Reply with quote
Code:
void gestionclavier_virgule()
{                             
  int8  Bouton=0,i=0x00,j=0x00; 
  float k=1, data=0;
  entier=0;                   
  decimal=0;                 
   while(Bouton != '*')
   {
        Bouton = GetBouton();
        if(Bouton == '*')   
             break;         
        i = ch_int(Bouton);
        printf(lcd_putc, "%d",i);
        entier = entier*10 + i;         
   }
   lcd_putc('.');

   while(Bouton != '!')
   {
        Bouton = GetBouton();
        if(Bouton == '!')   
             break;         
        j = ch_int(Bouton);
        printf(lcd_putc, "%d",j);
         k=k*0.1;
        data=data+k*j;
       decimal= float_int8(data);
   }
   lcd_putc('\f');
}void gestionclavier_virgule()
{                             
  int8  Bouton=0,i=0x00,j=0x00; 
  float k=1, data=0;
  entier=0;                   
  decimal=0;                 
   while(Bouton != '*')
   {
        Bouton = GetBouton();
        if(Bouton == '*')   
             break;         
        i = ch_int(Bouton);
        printf(lcd_putc, "%d",i);
        entier = entier*10 + i;         
   }
   lcd_putc('.');

   while(Bouton != '!')
   {
        Bouton = GetBouton();
        if(Bouton == '!')   
             break;         
        j = ch_int(Bouton);
        printf(lcd_putc, "%d",j);
         k=k*0.1;
        data=data+k*j;
       decimal= float_int8(data);
   }
   lcd_putc('\f');
}


In this fuction, "entier" and "decimal" are global variable. this fonction change the value for them.

Now, I have a problem: if I want to enter for example 5, I have to enter 5.0 because of my this function.

I hope you can give me some help for that, or maybe you have a good solution for a decimal value.

Hello,

Your code look to be duplicated.

If i understand, you use '*' for decimal separator and '!' as 'return' key ?

The first loop is breaking only if you type '*'. I think that you need to test for 'return' in this loop too.

as :
Code:

void gestionclavier_virgule()
{                             
  int8  Bouton=0,i=0x00,j=0x00;
  float k=1, data=0;
  entier=0;                   
  decimal=0;                 
   while(Bouton != '*' && Bouton != '!')
   {
        Bouton = GetBouton();
        if(Bouton == '*' || Bouton == '!')   
             break;         
        i = ch_int(Bouton);
        printf(lcd_putc, "%d",i);
        entier = entier*10 + i;         
   }

   while(Bouton != '!')
   {
        lcd_putc('.')
        Bouton = GetBouton();
        if(Bouton == '!')   
             break;         
        j = ch_int(Bouton);
        printf(lcd_putc, "%d",j);
         k=k*0.1;
        data=data+k*j;
       decimal= float_int8(data);
   }
   lcd_putc('\f');
}


Best regards,
dro

Thank you very much!!!!!!
you are intelligente!!!! Very Happy

the programm is very good, just change a little, I have changed
I have another question: do you know if "entier" is "signed int8", what can I do for enter a negatif value(-26.5, for example)

in my case, the experiment makes more than the intelligence. (even if I am a man)

For enter a negative value, i think that you need to use a special key (other than '*' or '!' like '-' if you have in your keyboard) or, you can presses twice '*' for indicate to change the sign. Do not forget that a signed int8 can handle only +127 to -127.

sorry for my bad English (normally, I speak French)
