Tracking Down Bus Anomalies
In this example, you are testing your new I
2
C circuit. Something is not working. You tell the master IC to send a message to the
slave IC. Then you expect to receive data back and an LED to light. The light never goes on. Where in the ten or so commands that
were sent out did the problem occur? Once you locate the problem location, how do you determine what went wrong?
You can use your oscilloscope, with its serial triggering and long-record length management features, to track down the problem in
both the physical layer and in the protocol layer of the bus.
