Ask about sprintf in ATMega8535

[incognito_prince]

Hi..

I'm using ATMega8535 to control my 2x16 LCD. My problem is when I use sprintf to convert the number to be displayed on LCD the LCD repeat the character after the desired character that I want to display. Anyone can help me? Thanks before..

here is the code:

char buff[33];
......
while(1)
{
//lcd_gotoxy(2,0);
//lcd_putsf("Actual Time");
lcd_gotoxy(0,0);
sprintf(buff,"%02d:%02d:%02d",hour,minute,second);
lcd_puts(buff);
detect_key();
if(dtkey==0xC)
{
jump=1;
menu();
}
}
.......

you may try this modification

while(1)
{
//lcd_gotoxy(2,0);
//lcd_putsf("Actual Time");

//lcd_gotoxy(0,0); //This line commented

lcd_clear(); //Add this line

sprintf(buff,"%02d:%02d:%02d",hour,minute,second);
lcd_puts(buff);

delay_ms(200); //may need this, check delay time

detect_key();
if(dtkey==0xC)
{
jump=1;
menu();
}
}
