We wrote a driver this week for the HUSB238 USB PD sink chip https://blog.adafruit.com/2022/05/04/plug-n-play-usb-type-c-dummy-pd/ - this IC is neat in that you can either use jumpers (really, resistor selection) to set the desired PD voltage and current ooooor you can use I2C for dynamic querying and setting. we have a wall adapter that can provide almost-all-PD voltages: 5/9/12/15/20 only 18 is skipped. The HUSB plugs into the USB C cable and, over the CC lines, will negotiate the PD request and commands. For example, we can ask what voltages are available and then iterate over the options…
