AVR Freaks

I'm trying to get humidity and temperature with a DHT-11 sensor interfaced with an ATMega16 at PIN no. 39 (Port A1).

Now, there aren't much (if any) libraries available in the internet, which I can use for ATMega and DHT-11. All the available ones seem to be only for Arduinos. I'm totally stuck here.

I got one set of dht11 c and h files for some Arduino and edited it. I wrote a program, and I've spent hours trying to get it work. But it does not. Could you please help me?

This is my C program:

#include <avr/io.h>
                             // special function registers
#include <stdio.h>              // sprintf()
#define F_CPU 4000000           // 4MHz Internal Clock
#include <util/delay.h>

#include "dht.h"
#include "lcd.h"                 //Fleury

#define DHTTYPE DHT11   // DHT 11


int main(void)

{
	{

	lcd_init(LCD_DISP_ON);
	lcd_puts("DHT11 initializing!");
	
	_delay_ms(2000);

}



while (1) {
	
	lcd_clrscr();
	
	float h = dht_gethumidity;
	float t = dht_gettemperature;

lcd_gotoxy(0,0);

lcd_puts("Humidity: ", h);
lcd_gotoxy(0,1);

lcd_puts("Temp.: ", t);

_delay_ms(1500);

}
}

This is my DHT.h file:

#ifndef DHT_H_
#define DHT_H_

#include <stdio.h>
#include <avr/io.h>

//setup port
#define DHT_DDR DDRA
#define DHT_PORT PORTA

#define DHT_INPUTPIN PA1

//sensor type
#define DHT_DHT11 1
#define DHT_DHT22 2

//enable decimal precision (float)
#if DHT_TYPE == DHT_DHT11
#define DHT_FLOAT 0
#elif DHT_TYPE == DHT_DHT22
#define DHT_FLOAT 1
#endif

//timeout retries
#define DHT_TIMEOUT 200

//functions
#if DHT_FLOAT == 1

#elif DHT_FLOAT == 0
