This app uses the Tektronix tm_measure library to decode I2C using a Tektronix MSO24 oscilloscope.

First the necessary blocks were added:

  • 1 CONNECT_MSO2X
  • 1 I2C_TRIGGER_MSO2X
  • 1 SINGLE_TRIGGER_MSO2X
  • 1 DECODE_I2C_MSO2X
  • 1 TEXT_VIEW

Each of these blocks must change the connection parameter to the correct instrument. The parameters were changed to match the setup: the clock_channel and data_channel parameters were changed to the proper analog or digital channel. The I2C_TRIGGER_MSO2X parameters were changed to trigger on the corrent signal. For example:

  • condition = address
  • addr_bits = 7
  • addr = 0010

therefore the actual address will be XXX0010 where X corresponds to a wildcard (0 or 1).

The blocks were connected as shown and the app was run.
