Evo ti za PIC19F4620. Može da se primeni praktično na bilo koji 8-bitni.

Code:

#include <xc.h> #include <stdlib.h> #include "hd44780.h" #include "cfg.h" #define _XTAL_FREQ 40000000 /* Crystal frequency in MHz */ unsigned long c; void interrupt ISR(void) {    if(TMR1IF)    {        TMR1IF = 0;          } } void main(void) { unsigned char i; char lcd[10];    RCON = 0b00011111;    for(i=0;i<10;i++){__delay_ms(100);} CMCON = 0x07; LATA = 0; TRISA = 0xFF; LATB = 0; TRISB = 0xFF; LATC = 0; TRISC = 0xFF; LATD = 0; TRISD = 0xFF; ADCON1 = 0x0F; LATE = 0x00; TRISE = 0x00; OpenLCD(); ClearLCD();    TMR1L = 0;    TMR1H = 0;    T1CON = 0b10000111;    TMR1IF = 0;    TMR1IE = 1;     PEIE = 1; GIEL = 1;    GIEH = 1; while(1) {        for(i=0;i<10;i++){__delay_ms(100);}        c = (unsigned long)((TMR1H << 8) + TMR1L);        ltoa(lcd, c, 10);        GotoLCD(0,0);        PutsLCD(lcd);    } }

Ovo ti broji samo u jednom smeru do vrednosti promenljive od dva bajta (65535).
