I'm looking for the i2c slave code example to run it on C51 compatible chip. My target is to make some device that can be externally configured by i2c bus. We are going to use dimax u2c-11 as i2c master http://www.xdimax.com/u2c/u2c11.html This device has a nice feature to select different i2c clock speed so I'm going to addjust it to my cpu slave module speed. Once again I need slave not master example. Thank you.
