The SDK is not written to support C++, only C. Unfortunately, this is not something we can support you on.

There are a few threads regarding C++ on this forum already, you may check some of them out to see if it can help you resolve your issue.

I'm compiling the example "usbd_hid_composite" in SEGGER studio with no problem but since our project is written in C++, when renaming main.c to main.cpp the compiler throws the following error:

I have tried to rewrite the HID for a composite keyboard + mouse device but the way the HID is defined in the library via macros makes it humanly impossible to decipher. Any suggestion?

You can download nRF5 SDK releases from this page. Just download and unzip the release to a location close to the root of your harddrive. Then follow the instructions in Getting started with nRF5 SDK and SES (nRF51 & nRF52 Series) and Getting Started to build examples.

I have seen that in previous SDKs, specifically nRF5 SDK v17.0.2, the following examples fit my needs very well:
infocenter.nordicsemi.com/.../usbd_hid_composite_example.html
Y
infocenter.nordicsemi.com/.../usbd_ble_uart_example.html

How do I install nRF5 SDK v17.0.2, I have Toolchain Manager V1.1.0 but I can only install new SDKs and the problem with these is that all the examples use Zephyr OS and I need bare metal examples. I think that sample programs are given, these should be neutral to be able to be ported to any platform or RTOS that one wants to use and not only centralize the entire SDK in Zephyr OS, that takes away a lot of flexibility from the platform.

You can reference the USB device driver for NRFX in nRF Connect SDK/Zephyr.

There is any available example to port USBD NRFX driver?

Thanks for replying quickly. I'll try with the library you mention, I'll comment on the progress.

Hi,

You may be able to integrate the NRFX USDB driver with Arduino, to implement the required functions.

Unfortunately, we do not support Arduino, so you will have to implement this yourself, or hope for some help from the DevZone community.

Best regards,
Jørgen
