I2C Sniffer? (msp430f2012, ccsv5)

Recommended Posts

I was wondering if there is any pre-existing code out there for CCS v5 and an msp430f2102-ish type device?  I'd like to setup a tiny project that monitors an I2C bus and logs filtered transactions over UART..  Specific addresses or data values, for instance.  The uart terminal program then could timestamp the log data, so I don't really need to worry about that part.


It's not ultra-critical, the data would just be useful to decypher in a side project I'm working on..  so honestly I am hoping that something like this already exists that I can just load-and-run and log the data.. post-process it later in Excel or something to extract out the meaningful data from the stream.
