Guys i'm trying to write a function that will be able to print more than one digit on the lcd screen coz the printf(LCD_PUTC," ") function does not print 0 before a digit i.e if you want lcd to print Time(01:00:45). It only prints (1:0:45) with the printf(" ") function. Here is the function but it does not work.
| Code: | Code:
void print_int(int num, int len)
{
if(len>=5) lcd_writebcd(num/10000);
if(len>=4) lcd_writebcd((num/1000)%10);
if(len>=3) lcd_writebcd((num/100)%10);
if(len>=2) lcd_writebcd((num/10)%10);
if(len>=1) lcd_writebcd((num/1)%10);
}
void lcd_writebcd(char n)
{
if((n>='0') && (n<='9')) //only decimal numbers are allowed
lcd_putc(n+'0'); //print character one at a time
} |
//I CALL THE FUNCTION AS FOLLOW IN THE MAIN PROGRAM
| Code: | while()
{
print_int(hour, 2); //suppose to print 2 digits i.e. xx
} |
can anyone help out here...
cheers |

printf() can do this. Look at the CCS example file EX_RTC, which
shows exactly how to do it. That file is in this folder:
c:\Program Files\PICC\Examples
Also, please don't double-post. Please go to your other post and
delete it. http://www.ccsinfo.com/forum/viewtopic.php?t=25761
As long as no one has replied to it, you can delete it. Just click on the
little "X" in the upper right corner, which is visible when you view the post. |
