pictureFrame

Handcrafted e-ink digital picture frame ecosystem — built as a meaningful gift. ESP32 firmware pulls pre-rendered images from a Symfony web app over WiFi; the companion web app handles image management, device configuration, and family sharing.

Project goal

Build gifted e-ink frames that stay personal and current over time, with no ongoing effort required from the recipient. One image per configured interval, cycling through a curated pool of family uploads and shared photos. Setup: scan two QR codes. Ongoing: nothing unless the recipient wants it.

Stack

Firmware: PlatformIO + Arduino framework (C/C++), ESP32 dev board
Web app: Symfony 8.0 (PHP 8.4+), PostgreSQL 16, Nginx-FPM
Local dev: DDEV — mirrors ~/src/aqua-iq setup
Git: git.edholm.me (self-hosted Gitea/Forgejo)
Domain: pictureframe.edholm.me

Hardware

Dev / V1 hardware (in hand)

ESP32 dev board (esp32dev), dual-core 240MHz, 4MB flash
Waveshare 7.3" 6-color e-ink (800×480)
SPI pinout: SCK=18, MOSI=23, CS=5, DC=17, RST=16, BUSY=4
4bpp packed, palette: BLACK=0x0, WHITE=0x1, YELLOW=0x2, RED=0x3, BLUE=0x5, GREEN=0x6 (same map as Spectra 6; 0x4 unused)

Target / V2 hardware (on order)

Waveshare ESP32-S3-ePaper-13.3E6 — 13.3" Spectra 6 (6-color), ESP32-S3 onboard
Spectra 6 palette: same as above — BLACK=0x0, WHITE=0x1, YELLOW=0x2, RED=0x3, BLUE=0x5, GREEN=0x6
Battery or plugin at recipient's choice

Design decisions

Server pre-renders all images to display-ready 4bpp per device model/orientation — ESP32 never transforms images
Device pull model: GET /api/device/{mac}/image → 200 (binary), 204 (no ready image), 404 (unknown MAC)
Atomic image write: display only refreshes after complete confirmed transfer; last good image persists through outages
Deep sleep between pull cycles (see ESP32 deep sleep memory)
Status via border color: yellow = sync fail, red = no WiFi
5-second button hold triggers re-provisioning (config wipe + AP mode)
Two-phase provisioning: AP mode (WiFi credentials) → STA mode (QR to account setup page)
Async image processing: Symfony Messenger (Doctrine transport), max_retries: 1
Image storage: storage/images/{id}/{model}_{orientation}.bin, relative paths in DB
PHP 8.1 backed enums for RenderStatus, TokenType, Orientation
Imagick for Floyd-Steinberg dithering (not GD)
No OTA firmware updates in V1 — API contract must not break without reflash

Infrastructure reference

For Docker/DDEV config, server location, and SSH details: ~/src/aqua-iq

Full spec

See _bmad-output/planning-artifacts/ — PRD, architecture, epics all complete as of 2026-04-27. Symfony web app scaffold + Vue SPA frontend scaffolded. Firmware fully rewritten with WiFi, provisioning, and deep sleep (firmware/src/).
