PicoProjects

Hybrid Arduino + Pico SDK monorepo for Raspberry Pi Pico W / Pico 2W projects.

Repository Layout

• projects/
  • creepy_halloween_sonar/ (Arduino / arduino-cli)
  • pico2w_lcd_soundboard/ (Arduino / arduino-cli)
  • pico_lcd_generative_art/ (Pico SDK / CMake)
  • pico_am_radio/ (Pico SDK / CMake)
  • kitchen_wall_clock/ (Arduino / arduino-cli)
• shared/
  • pico_display/ shared LCD driver + text rendering code (buildable by both toolchains)
• scripts/
  • root build/verify/flash/doctor/smoke helpers

Build Commands

Build all projects (default)

./scripts/build.sh --all

Build one project

./scripts/build.sh --project creepy_halloween_sonar
./scripts/build.sh --project pico2w_lcd_soundboard
./scripts/build.sh --project pico_lcd_generative_art
./scripts/build.sh --project pico_am_radio
./scripts/build.sh --project kitchen_wall_clock

Build without flashing

./scripts/build.sh --all --no-flash

Per-project build entrypoints

./projects/creepy_halloween_sonar/build.sh
./projects/pico2w_lcd_soundboard/build.sh
./projects/pico_lcd_generative_art/build.sh
./projects/pico_am_radio/build.sh
./projects/kitchen_wall_clock/build.sh

Verify / Smoke / Doctor

./scripts/doctor.sh
./scripts/verify.sh --all
./scripts/smoke.sh --project pico_lcd_generative_art

• verify.sh runs prerequisite checks, builds, preset sync regression, then smoke checks.
• smoke.sh reports PASS or explicit SKIPPED when hardware is unavailable.

Root CMake Superbuild

cmake -S . -B .build/root
cmake --build .build/root --target build_all
cmake --build .build/root --target verify_all

Available CMake targets:

• build_creepy_halloween_sonar
• build_pico2w_lcd_soundboard
• build_pico_lcd_generative_art
• build_pico_am_radio
• build_kitchen_wall_clock
• build_all
• verify_all

Flashing Behavior

When build scripts run without --no-flash, they attempt UF2 copy to:

• macOS: /Volumes/RPI-RP2 or /Volumes/RP2350
• Linux: /media/$USER/RPI-RP2, /media/$USER/RP2350, /run/media/$USER/RPI-RP2, or /run/media/$USER/RP2350

If no mount is present, flashing is skipped and reported.

Shared Change Policy

If files under shared/ change, rebuild all dependent projects (prefer ./scripts/build.sh --all or ./scripts/verify.sh --all).
