Could you guide me to a relevant example that demonstrates how to connect and use a gamepad or similar devices with the NRF700DK development kit, which is equipped with the nrf5340 chip? I'm interested in attaching a gamepad to the USB input.

I have produced a video showcasing my problem - youtube.com/.../DIEXafmKeOk. Essentially, I am seeking guidance on suitable application examples that enable me to establish a connection between a Logitech F310 gamepad and the nrf7002-dk development kit using the USB interface. The goal is to receive commands from the Logitech gamepad and transmit them to another device via Bluetooth.

Hi

I would presume that the gamepad need to be connected to a USB host, our current devices does not unfortunately support running as USB host. I will check with some of my coworkers if they have any good ideas.

Hello Runar,

I was wondering if you have any updates on this. I greatly appreciate your assistance. During my web search, I came across a repository that demonstrates the connection of the same joystick to an Arduino. Here's the link: https://github.com/AlanFord/Logitech_F310_and_Arduino.

I am uncertain about the compatibility of this solution with the Zephyr RTOS. Could you please provide some guidance on how I can modify this code to work with the Nordic Semiconductor?

Hi, it looks like there is a zephyr driver for the shield https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/boards/shields/max3421e/doc/index.html So I think can be an option if you have access the a shield that can act as USB host.

Hello Runar,

I appreciate your suggestion. Using a shield would be my last resort. However, I have discovered some code that enables USB to function as a host controller. Perhaps we can utilize this code to make USB act as a host.

The latest version of the Zephyr kernel supports the UHC USB host controller configuration, which can be found here: https://docs.zephyrproject.org/apidoc/latest/group__uhc__api.html

Additionally, there is another example of USB being used as a host controller in the "syubsys" directory located here: https://github.com/zephyrproject-rtos/zephyr/tree/main/subsys/usb/host All the code in this directory has been written by Nordic Semiconductor.

To illustrate my plan for utilizing this code, I have created a video demonstration, which can be viewed here: https://youtube.com/live/rsprPT60gJc

I hope to receive support for this approach and be able to use Nordic Semiconductor as a native USB host, rather than relying on a shield.

Hi, 

Unfortunately as you can see here, the USB peripheral for the nRF5340 is only a USB device https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fhardware_driver_usbd.html 

As you can read here: https://docs.zephyrproject.org/latest/samples/subsys/usb/shell/README.html the readme states  "

For the USB host functionality a supported host controller is required, currently it is only MAX3421E."

Thank you for your assistance! I'm not very familiar with the USB protocol, so I'll trust your expertise. Nonetheless, I appreciate all the help you've provided.

On a different topic, it seems that the shell example in the NRF SDK does not contain any useful code. It only includes the following:

/*

#include <zephyr/kernel.h>

int main(void)
{
    return 0;
}

Happy to help^^. 

I have asked regarding the Shell example. On our page it's listed as a part of the Zephyr project so I'm not sure who owns the example
