This isn't quite the same thing, I think. The Cypress one has decent software for reading individual PD packets and debugging PD/TCPM implementations.
Even if you can read out the packets with that, it doesn't look like it has a good pre-existing analysis software for it, which is a large part of the value proposition for the cypress version.
- nimish 2y agoThat's what sigrok or wireshark are for, IMO. Of course, you lose something for half the price. The ST one does have a protocol analyzer.
- Panzer04 2y agoWell, you can't read PD packets at that layer - they are only realistically visible at the driver layer and below, as the TCPM driver will manage the PD negotiation (and the main benefit of these analysers, at least for me, was to help write such a driver in the first place :))
