[En-Nut-Discussion] TWI aka I2C, not getting an ACK back?

[Douglas Pearless]

Hi,

I am trying to interface a DS1307 to the TWI.

I send it the address, and do not get an acknowledge back (I used a 
logic analyser to verify the return code I was getting in the software).

Any ideas (yes tried a DS1337 which has the same address too).

Cheers Douglas
