About

This project automatically sends Python code to the Pico-W when it connects to the Raspberry Pi. Running PicoScriptDeployer.py fetches the Wi-Fi SSID, password and IP-address from the Pi and saves them in config.txt, without overwriting existing details if new ones aren't found. The script waits for a Pico connection. Once a Pico is connected to the Pi, it updates the Wi-Fi credentials in main.py with the details from "config.txt" and then transfers the updated code to the Pico. This project is an extension for pico-network-serial-port.

Installation of Prerequisites

• Open terminal in Raspberry Pi and enter the below commands to install rshell.

  sudo apt update
  mkdir ~/python-environments
  cd ~/python-environments
  python -m venv rshell-env
  source ~/python-environments/rshell-env/bin/activate
  pip install rshell

Running the code

• Copy PicoScriptDeployer.py, config.txt, and main.py (code that needs to run on Pico) to the path ~/python-environments.
• Open terminal on the Raspberry Pi and enter below commands to run the code.

  cd ~/python-environments
  source ~/python-environments/rshell-env/bin/activate
  python PicoScriptDeployer.py

Setup

• Connect Pico-W (the target board) to the Pi through usb cable.

Developer Notes

• The main.py will be deployed only to the most recently connected Pico if multiple Picos are attached to the Pi.
• If PicoScriptDeployer.py cannot detect your Wi-Fi details, you can manually update config.txt with the correct credentials.
• After the code is deployed to the Pico, it will automatically reset and run the code.
• Files in the extras folder are optional for this project. See the points below for more details.
  • Run wifi_cred_getter.py on the Pi to retrieve its wifi SSID, password and IP-address, and save these details in config.txt.
  • Run PicoJustScriptDeployer.py on the Pi connected to the Pico to deploy main.py on the Pico without modifying the wifi credentials.
  • Run pico_id_getter.py on the Pi connected to the Pico to get the Pico VID and PID.
