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.
2  Products / Arduino Due / Not sure about my I2c setup, can somebody take a peak at it before I plug it in? on: March 14, 2014, 11:58:07 am

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:

3  Products / Arduino Due / Memory corruption with Due 1.5 on a Mac on: May 03, 2013, 02:04:35 pm

I recently ran into an odd problem with memory corruption when using the Mac version of the IDE. I was trying to run the crypto library, RELIC, on a Due and was getting odd results. Running the exact same sketch one the Windows IDE worked perfectly. For anybody else that might have simular problems, I was able to fix the problem by replacing g++_arm_none_eabi files with ones that I downloaded from https://launchpad.net/gcc-arm-embedded/+download
After I replaced them everything ran perfectly. I'm posting this here in case anybody else runs into a similar problem.

init failed for me using the sparkfun sd shield. The same sketch with the same shield worked fine with the UNO. Set SdChipSelect correctly and Tried SPI_HALF_SPEED and the other ones, but no luck. Not sure what I'm doing wrong.
