Yeah,You are right! Looking at datasheet those pins are analog by default..

Now Control Address and write address is what confuses me.Control Address is 0x26 as defined in arduino code,right? so what is write address?

Is SPI easier? I don't have many pins available but if I2C doesn't work I guess I don't have any other option.
