Project Numerous Shore

An IoT alarm clock using Micropython on a RPi Pico W

Setup

Dependencies

• uv

Wifi Credentials

Create a file on the device called credentials.txt with your wifi credentials in the following format:

SSID
PASSWORD

Static Files

Static and templates must be copied to the device.

uv run mpr put templates/index.html templates/

Install dependencies

Dependencies are contained in the lib folder.

Subdirectories such as lib/primitives must be created manually before running xrun.

Compile MPY files

mpr can cross-compile the python files to MPY files for the Pico W using xrun

uv run mpr xrun main

This will also change main.py to main.mpy, which is not recognised by Micropython when booting! If you wan to run the compiled code on boot, you must also copy over the main.py file:

uv run mpr put main.py .

Run Tests

Run tests by mounting the local file system on the device and running the tests in the tests folder.

uv run mpr --mount . run tests/test_main.py

Notes

If ampy can't connect make the port usable again

sudo chmod 666 /dev/ttyACM0

Open REPL with minicom

minicom -D /dev/ttyACM0 -b 115200

Or even better with mpr:

mpr repl
