Can I request a new requirement due to developing our product based CYPD3171-24LQXQ_cla platform? we know the CYPD3171-24LQXQ_cla platform support quick charge protocol such as PD3.0/QC4.0 etc, but we still need to integrated others private protocol such as Huawei SCP/OPPO VOOC to the platform, so we hope to open the platform PD stack source code to us and further to develop our product based CYPD3171-24LQXQ_cla, but currently PD stack is provided by the pre-compiled library and is inconvenient to us to integrate these function

Hi,

I'm sorry but we cannot share the PD stack source code as it is Cypress intellectual property.

As I had previously stated in my response, legacy charging code is available in the SDK and you can make the required changes in the application layer.

Best Regards,

Mallika

Hi,

The firmware source code can be downloaded from the link:

https://www.cypress.com/documentation/software-and-drivers/ez-pd-ccgx-power-software-development-kit

You can start with the CYPD3171-24LQXQ_cla project in the Power SDK and can add other charging protocols in a similar way as it is being already done for the legacy protocols (Apple Charging, BC1.2) in the firmware code.

>>Please let us know if you specifically want to modify the PD stack?

Hi,

Please install CCGx Power SDK: https://www.cypress.com/documentation/software-and-drivers/ez-pd-ccgx-power-software-development-kit

For CYPD3175 part, CYPD3175-24LQXQ_pa_direct_fb project can be used.
