Extract I2C read for particular slave address from huge log

Logic 2 Software

Hi Team,

We have a sporadic error case where our internal I2C reads show 0XFF data

But we wanted to cross verify with the raw I2C data from saleae capture.

I was successful in capturing the log but the csv file is too huge ~220GBs and .sal as well is ~3GBs

And there will be only one instance when our I2C read shows (false case : 0xFFs) invalid values.

I wanted to check whether we have any filter/plugin for I2C analysis targeted to read/write on a single slave address.

Any hints are of great help…

Thanks & Regards

Maybe my Re Search extension can help? It uses a regular expression search to find matching text returned from LLAs like the Async Serial analyser and the I2C analyser. You should be able to find it in the Extensions sidebar by typing “Re Search” into the search box.

Note that the search sees the data shown in the address and data columns in the Data Table rather than the text shown in the main display or terminal.

If the info is not classified you could also post the compressed csv and the .sal file somewhere.

so others could also have a look at it, and maby find a out of the box solution.
