Hi,

I2C, or IIC is very simple protocol comparing with other serial protocols; it's totaly depends on timing and synchronization. Please check the attached file which is details and code for your reference!

If you need anything else, just post here.

Enjoy electronics Wink

Hy deveshsamaiya,

I searched the Internet a long time for a good I2C-Code.
There were thousands of codes and exaples and I tried
everything but in the end I had to write my own one.

So please try it by yourself first it's very easy and if
you need help just send me a PM or make a post here.

Take a look at these links, they helped me a lot:
