| Doubts with MAKE32 |
 Posted: Tue Feb 01, 2011 4:26 pm |

Hi, I'm trying to use the make32() to combine 4 bytes data but I did it,
applying make32 the 4 bytes as a result I have 0x1781 and not as it should be 0x04D21781.
Somebody could say which is my mistake?
here my code:
| Code: | #include <18F452.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT
#use delay(clock=20MHz)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)// RS232 Estándar
int32 Pagina;
void main(){
Pagina = make32(0X04, 0XD2, 0X17, 0X81);
while (TRUE);
} |

How do you know this ? I don't see any code to display the result. |

I was using the Proteus in debug mode, mmm... but when I use the
printf() if I get the desired value,  it appears that
Proteus is the problem ...thank you... |

Look at this:
I modified your code and tested in on proteus, it's working, it shows:
(pagina:80877441) , is it you want?
| Code: |
#include <16F877a.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP,NOBROWNOUT
#use delay(clock=20MHz)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)// RS232 Estándar
int32 Pagina;
void main(){
Pagina = make32(0X04, 0XD2, 0X17, 0X81);
while (TRUE)
{
printf("pagina:%LU \r\n",pagina );
delay_ms(100);
}
