AVR Freaks

Hi,

I am using using Peter Fluery's i2c library for my ATMEGA2560. I am trying to do simple scan of the bus. I only have 1 device on the bus at address 0xC8, however the library says there is another device at 0xC9.  When I connect an analyzer up I see it reads the the following write command as a read.

Here is my code:

#include <asf.h>
#include "uart_config.h"
#include <util/delay.h>
#include <avr/power.h>
#include "i2cmaster.h"

int main (void)
{
	unsigned char ret;	
	
	uint8_t ack = 0;
	board_init();
	usart_init();
	
	printf("ATMEGA2560 i2c Scanner Rev 2\n\r");	
		
	i2c_init(); // initialize I2C library

	uint8_t address = 0;	 
	
	for( address = 0; address < 255;address++){				
		
		ret = i2c_start(address+I2C_WRITE);       // set device address and write mode
		if ( ret ) {			
			i2c_stop();			
		} else {
			printf("Found Device on 0x%02X\n\r", address);
			i2c_stop();			
		}
	}		

	while(true){			
	
	}
}

I would expect the i2c_stop() to release the bus and start all over. Any help is appreciated.
