But you wrote : "This practice is detailed in the I2C specification and makes a more robust design, which is probably why the original poster has the series resistors in there." I (still) don't think it was. I thought that there was a risk that the quote above could be read as a verification of the potential problem as outlined in the original post. Which was a non-problem based on a misunderstanding of the I2C bus (that devices pulls the SDA line *activily* both high and low). I was just trying to clear that out. Sorry for the mess and Best Regards, Jan-Erik. _______________________________________________ http://www.piclist.com View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
