Have you tried the lib of Peter Fleury too?

I've it not tested, bud it should be work great.

Hi wkrug

I tried peter flurrys library.. my code seems to compile fine but nothing is dispalyed on my lcd in my avr board...... here is the code that i have writted, it compiled fine but when i loaded the hexx file to my avr board nothing s displayed on the lcd...

#include <avr/io.h>
#include "lcd.h"

int main (void)

{

char buffer[7];
int num ;


DDRB |= (1 << 2); // Set LED1 as output
DDRC = (1 << 0); // Set LED2 as output

ADCSRA |= (1 << ADPS2) | (1 << ADPS1) | (1 << ADPS0); // Set ADC prescalar to 128 - 125KHz sample rate @ 16MHz
ADMUX |= (1 << REFS0); // Set ADC reference to AVCC
ADMUX |= (1 << ADLAR); // Left adjust ADC result to allow easy 8 bit reading

// No MUX values needed to be changed to use ADC0

ADCSRA |= (1 << ADATE); // Set ADC to Free-Running Mode
ADCSRA |= (1 << ADEN); // Enable ADC
ADCSRA |= (1 << ADSC); // Start A2D Conversions

/* turn on cursor */
lcd_command(LCD_DISP_ON_CURSOR);

//Clear the screen
/* clear display and home cursor */

lcd_clrscr();

for(; // Loop Forever

{

ADCH = num ;
/* convert interger into string */
itoa( num , buffer, 10);
lcd_puts("The velocity is \n");
/* put converted string to display */
lcd_puts(buffer);



if(ADCH < 128)
{
PORTB|= (1 << 2); // Turn on LED1
PORTC &= ~(1 << 0); // Turn off LED2
}

else
{
PORTB &= ~(1 << 2); // Turn off LED1
PORTC|= (1 << 0); // Turn on LED2
}

}

}

It looks beautyful, but where ist the lcd_init() comand ?

Ist the Port defination ok - Ar the Ports connected in the right way for the library ?

Look into description before use the library.
