| Printing counter (i) to LCD screen |

i got the lcd_putc working finally, but for my project i need to be able to do more than just that. as an example,
int16 i
for (i=1;i<=100;i++){
lcd_putc( "\fSending data to LCD.\n Here is data: ");
lcd_putc(i);
}
now i've tried many varitations on this theme, lcd_putc does not support the %lu printf stuff. what i get is a single hex character that gets printed out and incremented each loop.
what i need is a hex to ascii converter, and i'm suprised that there is not one already built in. seems like i cant be the only one that needs this sort of subroutine.
any help would be really appreciated, even if it is just a suggestion for an algorithm....
stuck on i

| Use the sprintf() function to put the data into a string and output the string to your lcd. |

RTFM? 
printf(lcd_putc,"Hello World %02X %08lu %04.4f\n",num1,num2,num3);
should work quite nicely. It uses printf, but passes each char in turn to lcd_putc.
Page 126 on the current manual and EX_LCDTH.C will give you some quick pointers.
