I2C 7 bit Address decoding problem

Postby Enova » Tue Apr 14, 2015 6:56 pm

Hi all,

I am trying to monitor I2C bus 7 bit address -3.3 volts - 400kb/s. I know that the slave's address is 0x30 but decoder gives 0x60. Is there any solution for this problem. You can find system details below.

Have you tried feeding the signals into the digital channels, and decode them there ?
