Surprise! I've just made another patch release to the 1.2 series, version 1.2.2. This adds a new LED blink code (1 7/8 s on, 1/8 s off) which indicates that only default USB power is available (no Power Delivery, no higher Type-C Current). This often occurs because the Sink is powered via a USB Type-A to Type-C cable. I've had a few users ask why the Sink can't get power from their charger, and the problem turned out to be that they were powering it in this way. Just today someone suggested adding another blink code for that case, and I liked that idea, so here it is.
