need help making USB OTG Audio and Power Delivery (PD) work properly

5angxr — Wed, 27 Nov 2024 02:11:59 GMT

I need help making USB OTG Audio and Power Delivery (PD) work properly when connected to either a phone or a computer.

I’ve already implemented USB OTG Audio, and it works fine on its own. However, I’m not sure how to integrate PD with OTG Audio. The implementation seems quite complex, and it might be difficult to explain fully within this forum format.

Could you provide any advice or resources to help me tackle this issue?

Hi @5angxr,

What device are you trying to implement this into?

What P/N are you using?

BR,
Edwin.

On the RT1040 SDK, you will find the "USB Type-C PD Stack Reference Manual" and "USB Type-C Power Delivery Stack User Guide", which explain in detail everything relating PD for the RT1040. You can find these documents on the following path:

thanks for your reply, and sorry for my late response. Do "USB Type-C PD Stack Reference Manual" and "USB Type-C Power Delivery Stack User Guide" tell users how to integrate PD with OTG Audiom?

Hi @5angxr,

This document does not mention how to integrate that specific use case, but it is the closest we have to your PD application.
