Installation

• Install Circuit Python version 8.0.0 or later on to the Pico W (at time of writing this version is still in beta)
• Into the lib folder copy the adafruit_hid folder from the library bundles [https://circuitpython.org/libraries]
• Into the lib folder copy adafruit_httpserver.mpy from the library bundle
• Into the main folder copy all the files in this repo.
• Edit secrets.py and enter your own WIFI_SSID and WIFI_PASSWORD

Admin Interface

The admin interface allows you to check boot logs, and reboot the picow amongst other things. The admin interface runs on port 5001 by default. To see the list of avaiable commands look in: control_handler.py

TODO

1. Test on a Google TV device (this might require HID Descriptor changes in a boot.py file see: [https://learn.adafruit.com/customizing-usb-devices-in-circuitpython/hid-devices] to allow the "Netflix buttons"
