pic16f84a and lcd driver modification
PostPosted: Mon Jan 23, 2006 12:31 am     Reply with quote

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

As long as no one has replied to it, you can delete it. Just click on the
