Thanks again everyone for submitting sample captures!
8 people submitted captures, and we ended up with samples of I2C, Serial, SPI, and manchester data, with over 15 different devices / protocols.
We’ve been working on 4 different specific extensions to start with - the AK09916 and HDC2080 I2C sensors, the TUSB422 I2C USB Type-C Power Control IC, and the USB PD (BMC) signal.
I’ve been working on the USB PD HLA (Biphase Mark Code), and just published to the marketplace. You can find the source here too: https://github.com/saleae/hla-usb-pd.
In addition to missing most vendor data object decoding and all extended header & data block decoding, it does support quite a lot - all the basics, plus it decodes data objects for all other data types. (source capabilities, sink capabilities, etc).
But there is a big caveat. To use it, you need to find a way to reliably record the USB Type-C CC pin using a digital input. The analog recording I got from @P.Jaquiery would have required a threshold of 0.4 volts to decode properly, which our device does not support. This would likely require the user to record using a digital comparator first. Eventually, we’ll want to add analog to digital conversion in our application to support this. In the meantime, I exported the analog channel, and modified our software’s digital simulation code to read a modified version of the export, to get the data back into the SW as digital.
The github post includes a digital clipping of @P.Jaquiery’s sample capture to demonstration purposes.
