tfaour	f74085cedf	Add third button: "scan to manage" QR overlay on the current photo ... Pressing the manage button (GPIO1) overlays a small QR code -- "SCAN TO MANAGE" -- in the top-right corner of whatever photo is currently on screen, linking to the server's config page, then reverts to the plain photo after 30 seconds. The overlay is spliced into the existing streaming fetch as chunks pass through (frame_client.c's http_read_fn), rather than buffering the full 192,000-byte frame in RAM: only the small overlay rectangle itself (~30KB) is ever held in memory, generated via new stride-parameterized drawing helpers (epd_draw_*_ex in epd_draw.c) that let the existing QR/text drawing code target an arbitrarily-sized buffer instead of a full-frame one. epd7in3e.c is untouched -- it has no idea an overlay exists.	2026-07-19 00:50:07 -04:00
tfaour	b9649c35ec	Skip redundant panel refreshes and fetch the image before the config check ... The panel driver now splits writing a frame into its SPI buffer (epd_write_frame(), which also computes a CRC32 as it streams) from actually triggering the physical refresh (epd_turn_on_display()). frame_client.c compares the new CRC against the last one that was actually refreshed (persisted in NVS) and skips the refresh entirely when they match -- e.g. a reboot redisplaying the same photo before the server's refresh interval elapsed no longer causes a visible flash for no visual change. Also reorders the per-wake fetch cycle: the image fetch (15s timeout) now goes before the config check (3s timeout), instead of after. The config check's tighter timeout was intermittently tripping on connection-setup latency that's common on the first request after waking from a long deep sleep (e.g. stale ARP); putting the more tolerant request first absorbs that latency, and the config check then rides the connection it already warmed up.	2026-07-18 23:51:01 -04:00
tfaour	d395cf3bb9	Add two physical buttons: factory-reset and next-photo ... Factory-reset (GPIO3, hold 10s): clears stored WiFi/server config and restarts into provisioning -- the deliberate, USB-free replacement for the earlier reverted RST-based auto-reprovisioning idea. Next-photo (GPIO2, tap): wakes the device and forces the server to advance immediately via a new POST /frame/advance, instead of waiting for the refresh interval. Both buttons arm themselves as deep-sleep GPIO wakeup sources so a press is noticed promptly even while asleep. Also makes GET /frame/image side-effect-free: it now only advances once refresh_interval_s has elapsed since the current photo was set (tracked server-side), so a device reboot for any reason just redisplays the current photo instead of silently skipping ahead. The server maintains a small reorderable upcoming-photos queue, viewable and rearrangeable from the web UI.	2026-07-18 23:28:36 -04:00
tfaour	7013311249	Add READMEs, docs, and LICENSE for publishing ... - LICENSE: MIT, with attribution notes for the vendored qrcode/epaper_fonts/ dns_server code and the epd7in3e driver's transcription of Waveshare's register sequence. - Top-level README.md: project overview, hardware list, quick-start pointing at firmware/ and server/, repo layout, license, Claude Code attribution. - firmware/README.md: full rewrite (was still the stock ESP-IDF captive portal example's README) -- build/flash instructions, Kconfig reference table, first-boot walkthrough, and how to reset to provisioning mode via NVS erase (the only way in right now; a proper reconfigure trigger is a future addition). - docs/hardware.md: wiring table + parts list + strapping-pin/SPI-speed notes. - docs/architecture.md: sequence diagram and walkthrough of the full provision -> connect -> fetch -> display -> sleep cycle, plus the reasoning behind doing image processing server-side and reusing Immich's face detection instead of bundling a detector. - server/README.md: fixed stale endpoint docs (missing GET /frame/config, POST /api/config still describing removed immich_url/api_key fields).	2026-07-18 16:47:30 -04:00
