USB PD AVS support in X-CUBE-TCPP

clement_roblot · ‎2025-10-15

Hello,

I don't seam to see anything related to the implementation of the USB PD AVS system to allow a sink to request voltages of up to 48V. Am I miss-reading the X-CUBE-TCPP code? If it is missing, is there a plan to implement it?

Thanks a lot

Have a nice day

Hi @clement_roblot

AFAIK, you can extend the USB PD stack to parse and handle APDOs (Augmented PDOs) for AVS. Also, X-CUBE-TCPP package already support EPR mode. No hardware platforms for EPR (up to 240W) are provided yet.

Oki doki, at least I will not be re-inventing the wheel if I implement that myself. Thanks a lot @FBL
