# 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/`).
