hc05.h includes :


io.h
delay.h
usart.h
string.h

hc11.c is :

#include<io.h>
/*Includes io.h header file where all the Input/Output Registers and its Bits are defined for all AVR microcontrollers*/

#define F_CPU 8000000
/*Defines a macro for the delay.h header file. F_CPU is the microcontroller frequency value for the delay.h header file. Default value of F_CPU in delay.h header file is 1000000(1MHz)*/

#include<delay.h>
/*Includes delay.h header file which defines two functions, _delay_ms (millisecond delay) and _delay_us (microsecond delay)*/

#include<hc05.h>
/*Includes hc05.h header file which defines different functions for HC-05 Bluetooth Module. HC-05 header file version is 1.1*/


void main(void)
{
delay_ms(500);
delay_ms(500);
/*Delay of 1s*/

usart_init();
/*USART initialization*/

hc_05_bluetooth_transmit_string("ABLab Solutions");
/*Transmits a string to Bluetooth Module*/

hc_05_bluetooth_transmit_byte(0x0d);
/*Transmits Carriage return to Bluetooth Module*/

hc_05_bluetooth_transmit_byte(0x0a);
/*Transmits New Line to Bluetooth Module for new line*/

hc_05_bluetooth_transmit_string("www.ablab.in");
/*Transmits a string to Bluetooth Module*/

hc_05_bluetooth_transmit_byte(0x0d);
/*Transmits Carriage return to Bluetooth Module*/

hc_05_bluetooth_transmit_byte(0x0a);
/*Transmits New Line to Bluetooth Module for new line*/
}
/*End of program*/






please help me!!!

continue of hc05.h :

temp=usart_data_receive();

for(i=9;hc_05_buffer2[i]!=0;i++)

hc_05_buffer2[j]=hc_05_buffer2[i];
j++;
}
hc_05_buffer2[j]=0;

if(!(strcmp(hc_05_buffer1,"OK")))
{
return 1;
}
else
{
return 0;
}
}

unsigned char hc_05_bluetooth_pin_change(char *new_pin)

}

#endif

thanks I did that but I also saw these errors:
