Driverless RNDIS USB WIFI Dongle

A Driverless RNDIS based wifi adapter based on pi pico w to enable usb wifi wlan on Windows on ARM devices like Windows on Raspberry pi 4 that makes use of the default driver of Windows RNDIS drivers

3 Steps connect to Wifi with PicoPiFi

1) Download the UF2 firmware and index.html

2) Upload Firmware to pi pico w

3) Open the index.html locally or navigate to https://sidd-kishan.github.io/PicoPiFi/ to control the wifi adapter

A RNDIS example that came with CherryUSB slightly modified to run on a Raspberry Pi Pico. Lets the Pico pretend to be a USB Ethernet device and CDC port to manage the device.

Build dependencies

On Debian:

sudo apt install git build-essential cmake gcc-arm-none-eabi

Your Linux distribution does need to provide a recent CMake (3.13+). If not, compile CMake from source first.

Build instructions

git clone --depth 1 https://github.com/sidd-kishan/PicoPiFi
cd PicoPiFi
git submodule update --init
cd pico-sdk
git submodule update --init
cd lib/
git submodule update --remote
cd ..
cd ..
cp -R rp2040/ CherryUSB/port/
rm -rf build/
mkdir -p build/
cd build
cmake ..
make -j$(nproc --all)

Copy the resulting PicoPiFi.uf2 file to the Pico mass storage device manually.
