i want drive a ds1307 with ATmega32 in assembly

(ATmega32 works in 8 MHZ internal oscillator mode)

i use this simple program for drive ds1307 and its not working ...

leds randomly turn on and off

the purpose of this program is first send primary Values to ds1307

(second/minute/hour/day/month/year)

and then reading second and send it to porta.(to show on leds)

would you please correct this program or write another simple

program like this one

(i am beginner in assembly and i searched internet and found nothing )

attention: this mode i used in my program called hardware i2c mode which is used

pc0 and pc1 as scl and sda and use registers like twbr/ /twsr/twcr/twdr
