Where I can find the example of usbpd_dpm_user.h ?

[Eremizin]

Hello!

I am tryig to create my own USBPD project on P-NUCLEO-USB002, and using UM2552 manual.

I add to project some files (see screenshot) and have compile error.

On the page 20 there is string: "For details see the file usbpd_dpm_user.h, which contains the structure definition for USBPD_HandleTypeDef." And the thing is that there is no such file in X-CUBE-USBPD STM32_USBPD_Library files. Only in Projects\STM32F072RB-Nucleo\Applications\USB_PD\EVAL_FUSB307_DRP\Src I can find it, but I dont think, that it is correct to use it in my project.

Dear @Eremizin​ ,

you could find different examples in the different STM32 FW packages (G0/L5/G4).

https://github.com/STMicroelectronics/STM32CubeL5/tree/master/Projects/STM32L552E-EV/Applications/USB-PD/USB-PD_Consumer_1port

Hello, @Yohann M.​ .

Thank you for answer!

Ok, G0/L5/L4 this models have UCPD on the board.

But if want to use x-code-usbpd with F0?

There is (https://github.com/STMicroelectronics/STM32CubeF0/tree/master/Projects) no examples for usb power delivery, looks like.

I just little understand, how I have to create this files?

Because STM32CubeMX generate it when I am using G0 series controller, but it is have different name.

But when I trying to use library after read the user manual um2552 there is no enouth info to create project.

I understand that it is complex and difficult project, and I understand that I have to read alot of info, but what I have to read?)

Even in USB-PD Core Stack User Maual this files are not included and looks like this files I have to write by myself, but how to do it correct?

Hello,

DPM user code is a common code between all the platforms. You may use G0/L5/G4 code as example and use it for your F0 applications.

In the X-CUBE-USBPD, you will have the same files as well:

} USBPD_HandleTypeDef;

This structure is an user structure to be tuned for own USB-PD usage.

Could you please clarify your compilation issues?

At 1st, I can see that the stack library you use is not correct one. For P-NUCLEO-USB002, you have to select 'USBPDCORE_PD3_FULL_CM0_Keil.lib'.

For your information, old applications used for P-NUCLEO-USB002 (MB1303) are available in the package V2.1.0 in github:
