Hi,
This is not a ticket!
I just want to share a simple application that I have built for the nRF52840. It's a USB keyboard.
The example also shows how to handle buttons states (press and release) using the button_app library.
It supports nRF5_SDK versions starting from v15.3.
Toolchain: Segger.
To compile the application, copy the application folder into the examples/peripheral folder.
Make sure to do a full erase before running the compiled firmware.
Also don't forget to use the nRF usb connector.
Once your application is running, your device should be detected as a Keyboard named nRF52 USB Keyboard, you can change that in the sdk_config.h file.
best regards,
