Topic: Not sure about my I2c setup, can somebody take a peak at it before I plug it in? (Read 474 times) previous topic - next topic

I am attempting to connect a SOIC 8 I2C chip, the ATSHA204 to a Arduino Due.  Attached is an image of the setup.
I've read some post's in the forum that I need to be careful about using pull-ups in the I2C pins or I can damage the controller.

If I plug this in, am I good to go or is there trouble?

Thanks!



I plan on using this library for it:

The datasheet for the ATSHA204 is at:

You are powering from 3.3V and pulling up to 3.3V?
Should be good to go.

Awesome! thanks for the feedback. Software I'm OK with but everything is a guess for me when it comes to hardware. I'll test it out tonight when I get home.
