CCG2+NCP81239 car charger reference design source code

Hi, rajath bhargav:

You had released the CCG2+NCP81239 car charger reference design source code to me around July, 18. My application has a MCU to control CCG2 and NCP81239 through CCG Host Processor Interface(HPI). My question is the source code you released to me include HPI or not ? I did not find relative files. How do I add HPI to the source code, or you can release me the source code include HPI? I already got HPI document through NDA flow. Thanks.

Hi William,

By default, HPI in the source code is disabled, since CCG2 has a small flash and inclusion of HPI might leave less space for customization.

If you can optimize your code and include HPI, you can enable it in this location -

Firmware\SDK\CYPD2134-24LQXI_PA_NCP82139\CYPD2134-24LQXI_PA_NCP82139.cydsn\src\pd_common\usbpd.h

In the 'usbpd.h' file, you find this:

/* HPI Configuration

* HPI_SUPPORTED

* HPI_NOT_SUPPORTED

*/

#define HPI_CONFIGURATION (HPI_NOT_SUPPORTED)

You have to change (HPI_NOT_SUPPORTED) to (HPI_SUPPORTED)

After this you can build your application as before and program the device. Be sure to optimize the code and not run out of flash size.

Best regards,

Rajath
