This will generate a firmware file: `build/firmware.uf2`. Reboot your Pico board in bootloader mode, and copy it to the RPI disk.
|
||||
|
||||
The device will reboot, register as a USB RNDIS device, and add a network to your computer.
|
||||
Run a browser, and open 192.168.3.1, you should see a device dashboard
|
||||
The device will reboot, register as a USB RNDIS device, and add a network and a removable read-only disk to your computer.
|
||||
Open the new drive, named `Mongoose`, and double click on its `INDEX.HTM` file; your browser should open and you should see a device dashboard.
|
||||
|
||||
Alternatively, you may just run a browser, and open 192.168.3.1,
|
||||
|
||||
Note: USB stdio in the Pico-SDK is done in background with TinyUSB and an interrupt to hide it from the user and periodically call tusb_task(). When we use TinyUSB, that code is removed from the compilation list; so this example uses UART stdio (UART 0) to keep things simple and focused on the RNDIS example. If you want to see the console output, connect an USB-to-UART or a low-voltage-TTL-to-RS-232 adapter to GPIO0
|
||||
|
||||
Note for Mac users: For this example to run on Mac, please set `DUAL_CONFIG=1` in `CMakeLists.txt` before building; this enables CDC-ECM. Please notice that Windows may not recognize the mass-storage device in that case.
