This project is an ESP-IDF application for ESP32-S3R8 based PaperMono devices. It includes basic demos for display refresh, clock, battery status, brightness, IMU, microphone waveform, RGB LED, buzzer, Wi-Fi scan, NFC scan, LoRa, TF card, sleep/wake, and shutdown behavior.

IDF Build

Tool Chains

ESP-IDF v5.5.1

Fetch Components

Component repositories are pinned to full commit hashes in repos.json. Project-specific ESP-IDF and Arduino adaptations are stored in patches/.

Check the currently installed components without changing them:

python fetch_repos.py check

Fetch components into an empty checkout:

python fetch_repos.py

Existing component directories are never overwritten by default. To rebuild them, the replacement must be explicit; the script moves the existing directories into _component_backups/ before installing the fetched copies:

python fetch_repos.py fetch --replace

Use --repo NAME to process one component and --output-root PATH to test in an isolated directory. --source-root PATH can use previously cloned PATH/NAME repositories as an offline mirror while retaining the locked commits and patches from repos.json.
