9-Digit number to LCD

[Henk]

Hi Guys.

I need to diplay a 9-digit number on a 2x16 lcd display, and wrote the following code to do this. It works fine accept at the point where the 5th digit changes from a 6 to a 7, or is greater than 7 to start with.

e.g. value is 999969999
when incremented by one, should be 999970000.

I instead get 99997}"ú7. i.e. the last 5 digits are garbage.


here's the routine:

void DisplayHundMillions(x,y,int32 value){

int HM,TM,M,HT,ToT,T,H,tens,units;
int HMASCII, TMASCII,MASCII,HTASCII,ToTASCII,TASCII,HASCII,tensASCII,unitsASCII;

HM=value/100000000;
TM= (value-(HM*100000000))/10000000;
M= (value-(HM*100000000)-(TM*10000000))/1000000;
HT= (value-(HM*100000000)-(TM*10000000)- (M*1000000))/100000;
ToT= (value-(HM*100000000)-(TM*10000000)-(M*1000000)-(HT*100000))/10000;
T= (value-(HM*100000000)-(TM*10000000)-(M*1000000)-(HT*100000)-(ToT*10000))/1000;
H= (value-(HM*100000000)-(TM*10000000)-(M*1000000)-(HT*100000)-(ToT*10000)-(T*1000))/100;
tens= (value-(HM*100000000)-(TM*10000000)-(M*1000000)-(HT*100000)-(ToT*10000)-(T*1000)-(H*100))/10;
units=(value-(HM*100000000)-(TM*10000000)-(M*1000000)-(HT*100000)-(ToT*10000)-(T*1000)-(H*100)-(tens*10));

HMASCII=HM+48;
TMASCII=TM+48;
MASCII=M+48;
HTASCII=HT+48;
ToTASCII=ToT+48;
TASCII=T+48;
HASCII=H+48;
tensASCII=tens+48;
unitsASCII=units+48;

Lcd_gotoxy(x,y);
Lcd_putc(HMASCII);
Lcd_putc(TMASCII);
Lcd_putc(MASCII);
Lcd_putc(HTASCII);
Lcd_putc(ToTASCII);
Lcd_putc(TASCII);
Lcd_putc(HASCII);
Lcd_putc(tensASCII);
Lcd_putc(unitsASCII);
}

Just can't find this bug.

This seems a very hard way to do this. You could just printf the number:

Thankyou very much. I thought pintf applied only to RS232.

It worked perfectly
