cosmic-paste

A vanilla JavaScript/HTML page to paste from the clipboard to the Cosmic Unicorn

Paste from clipboard to the Cosmic Unicorn (32x32 1024 pixels)
Paste from clipboard to 4 Cosmic Unicorns (64x64 4096 pixels)

Install required libraries

Connect your Pico to the computer and run Thonny. Select your Pico by clicking on the bottom right corner in Thonny. You should see the list of files on the Pico in the bottom left section. Stop any running process by clicking the Stop icon.

In Thonny, go to Tools -> Manage Packages...

Search for microdot_asyncio and install that. This will copy some files into the lib/ folder on your pico. It is needed for the web server that we use (same as cosmic_paint). Also search for and install micropython-phew.

Setup WIFI_CONFIG.py and copy network_manager.py

This script uses and requires the same WIFI_CONFIG.py that many of the other WiFi examples use (like cosmic_paint). That will need to be setup like this:

SSID="fill this in with network name"
PSK="fill this in with password"
COUNTRY="GB or US or your country"

You will also need to upload network_manager.py from the common folder

• micropython/examples/common

Installing the code on your Cosmic Unicorn Pico

• From the repo, upload cosmic-paste.py on your Pico.
  • Optionally copy cosmic-paste.py to main.py if you want it to start on boot
• In Thonny, run the file on the Pico, and get the IP address from the console
  • If it does not run, or you do not see the IP address, then setup WIFI_CONFIG.py or install required libraries and try again.
• Copy cosmic-paste/config-unicorns.example.json to cosmic-paste/config-unicorns.json
• Edit the file cosmic-paste/config-unicorns.json with your Unicorn IP address.
• Upload cosmic-paste/config-unicorns.json to your Pico in a cosmic-paste/ folder.
• Upload cosmic-paste/cosmic-paste.html on your Pico in a cosmic-paste/ folder.

Load the user interface at http://<your-pico-ip-address>/
