MakerspaceNetwork

In-house method for communitcation between computers and Raspberry Pi PicoW's.

For Desktop: mint/server.py

Python server for desktop (tested with Linux Mint). Uses aoihttp to be asynchronous, so we can do other things while still serving.

• To INSTALL: copy server.py, index.html, and uAio.py files to your serving directory.
• Currently the program will attempt to get the ip address for hosting using hostname which has been tested on linux mint. Otherwise it will revert to "localhost"
• serves index.html (GET at "/") To run use:

python3 server.py

May have to install aiohttp with:

pip3 install aiohttp

For PicoW: picoW/code.py

PicoW server using adafruit's requests

• To INSTALL: Download and copy the circuitpython uf2 to the Pico from:
  • https://circuitpython.org/board/raspberry_pi_pico_w/
• COPY: all files and folders in the picoW folder to the Pico. Thecode.py file should run automatically on the Pico, but use Thonny (recommended) to debug.

Makerspace POST protocol:

This simple protocol, in JSON format, facilitate sending data between picos and the main server.

e.g.

{
    'action': "getTime", 
    'value': ""
}

• the servers handle POST data in JSON in the form (where "lightON" is an example value). 'action' is a single string for quick messages/instructions. "value" can be any string, you just have to write the code to handle it.

• the server returns the 'rData' dictionary to pass info back to the calling computer with:

  • rData['item']
  • rData['status']

(Note: on the webpage (client) the returned data is processed and renamed "data")
