Saleae team - we would love samples of protocol captures!

For now I’m most interested in the “bubble” text and I haven’t really explored the data table at all. I’m often comparing logging from the DUT as async serial data with the TUSB422 traffic. The logging tells me about the internal state of the system and something about timing, and the I2C traffic tells me what’s actually happening. There are a whole bunch of interacting state machines that are pretty much direct implementations of the state diagrams given in the “Universal Serial Bus Power Delivery Specification” so gaining insight into how those machines are interacting is fundamental to figuring out what the system is doing. I’m using the logic analyzer as a firmware debugging tool much more than I’m using it to debug the hardware at present.
