Unable to get the ACK from the I2C device - Harischandra Prasad Tirumani - Jul 19 10:24:00 2005
I am trying to access 24C32 (I2C) through AVR2313
using PD0(SDA), PD1(SCL). But I am not receiving the
ACK from teh device. I have connected the same SCL,
SDA, to PC and I have tried. I am getting teh ACK
from device, means in hardware there is now problem.
For the trail I have PD0 to PD4 and PD1 to PD5 and
PD0, PD1 are using as output and PD4, PD5 are using as
input, even then I am not abel to receive the ACk.
I am using 4MHz crystal with AT90S2313
How can I proceed with this?
