Info screen: full /config + /state dump, replaces identity screen

2026-06-14T22:37:51+00:00

Previously the 4-line "identity" screen showed only viewport name, mDNS host, IP, and state. Expanded to 15 lines covering the full GET /config + GET /state output (name, host, ip, state, configured, scrypted, orientation, brightness, idle, fw, uptime, frames, errs, free heap, free PSRAM), label/value pairs left-aligned with auto-scaled font. Renames "identity" → "info" throughout — symbol, log messages, README/TESTING references. Also: - Move the info-screen render's big locals (~1.6 KiB: lines[16][80] + scrypt[256] + vp_name[64]) to BSS. The touch task's 3 KiB stack was overflowing on every long-press, leaving whatever frame was previously on the panel — gave the appearance of a "blue screen" after the M5 test pattern. - Drop the ≥5 s touch factory-reset gesture and remove all stale references to it in docs and comments. NVS wipe is now a USB-side `idf.py erase-flash` operation only. - M5 follow-up TODO in jpeg_decoder.c: solid green renders ~black and solid blue renders green; not a byte-order issue (BGR setting turns red into blue). Tracked as a known M5 gap.

M3 done: drop boot test, fold BOOT button into touch long-press

2026-06-14T21:41:03+00:00

The Waveshare ESP32-P4-ETH board exposes BOOT on GPIO 35, but at runtime that pin is owned by the EMAC TXD1 signal. No usable GPIO is wired to a separate user button, so the BOOT-button task could never fire. Move both BOOT-button behaviours onto the touch panel: - ≥1.5s hold → 15s identity overlay (was BOOT short-press) - ≥5s hold → factory reset (was BOOT long-hold) Short tap (<500ms) still toggles wake/sleep. Long-press fires while the finger is still down so the user gets immediate feedback at each threshold. Also strip the R/G/B 6 s boot test sequence — the panel now renders correctly, so it's no longer useful diagnostically. Boot subsystem flags drop the trailing B column: [EMHDJT].

M3 WIP: DSI bring-up + state machine + identity overlay

2026-06-14T20:53:33+00:00

DSI / panel: - LDO_VO3 acquired at 2500 mV (VDD_MIPI_DPHY) — without this the PHY PLL busy-waits forever inside esp_lcd_new_dsi_bus. - PSRAM bumped to 200 MHz (CONFIG_IDF_EXPERIMENTAL_FEATURES) to keep the DPI fed without underruns. - Pi-7"-style 800x480 panel init (REG_POWERON, PORTA/PORTB/PWM/PORTC) + 16-bit RGB565 framebuffer with portrait-mode rotation buffer in PSRAM. Currently shows garbled output — known issue, next commit switches to the TC358762-bridge-aware init sequence. State + UX: - viewport_state simplified to AWAKE/ASLEEP only; "unconfigured" is a flag, not a state. Tap always toggles; content choice (identity vs frame) is driven by the configured flag. - BOOT button arms a 15 s identity overlay via local_screens_overlay; expired callback returns to prior state. - Boot-done indicator: two backlight flashes (no usable LED GPIO on the Waveshare board — GPIO 35 BOOT is shared with EMAC TXD1). - Best-effort subsystem init in app_main; display init deferred to its own task so a panel hang can't block networking. Display test pattern: solid R/G/B for 2 s each on boot to characterize the garble independent of text rendering.

Identity screen: name + hostname + IP + state, auto-scaled

2026-06-14T16:39:08+00:00

local_screens_show_ip() now renders four lines instead of two — all the device's runtime identity at once: line 1: viewport name ("mudroom" / "viewport" if unconfigured) line 2: mDNS hostname ("viewport-mudroom.local" / "viewport.local") line 3: IP ("192.168.1.42" / "no network") line 4: state ("awake" / "asleep" / "unconfigured") Same screen is shown on first boot, after factory reset, and as a 15s BOOT short-press overlay — operator always has the device's full identity one button-press away (find it on the LAN, confirm name + configuration without curling). Font scale is auto-picked: the largest integer scale (1×–6×) where the longest line fits within 90% of width AND all four lines plus inter-line spacing fit within 90% of height. Works for both portrait (480×800) and landscape (800×480) without separate code paths. Font expanded to cover the new strings: - All lowercase a–z (added b, f, h, j, k, m, q, s, u, x, y, z). - Punctuation: dash, slash (digits, period, colon already covered). Fallback policy unchanged: unsupported chars render as blank, which keeps the table tight and the failure mode visible rather than crashing. README "Local rendering" + TESTING.md M8 updated to describe the four-line identity layout and show both the unconfigured-boot and configured-overlay example outputs. Build verified clean against ESP-IDF 5.4 (binary ~873 KB, +1.6 KB for the expanded font).

M8: local screens (IP + Loading) + BOOT button

2026-06-14T04:15:27+00:00

local_screens.{h,c}: - Embedded 8x8 bitmap font sized to a 95-char table; only the glyphs used by today's strings (viewport.local, the IPv4 string, Loading...) are populated. Unsupported chars render blank. - 768 KB PSRAM scratch FB at panel-native dims. - local_screens_show_ip() — two centered lines: "viewport.local" Scale 3x portrait / 4x landscape; centered vertically. - local_screens_show_loading() — centered "Loading..." at scale 4x/5x. - local_screens_restore_for_state() — repaint after BOOT-overlay expiry: UNCONFIGURED -> IP screen; AWAKE/ASLEEP -> black FB (next /frame or sleep handles the rest). - All paths go through display_present_rgb565() so orientation rotation is automatic. button.{h,c}: - Polling task at 30ms, active-low with internal pull-up. - Short press (<5s, released) → backlight on, IP overlay for 15s via esp_timer one-shot, then restore. - Hold ≥ 5s → nvs_config_reset() + esp_restart(). - PIN_BOOT_BUTTON = GPIO 0 is a TODO placeholder. ESP32-P4 strap pin GPIO35 is owned by RMII TXD1 at runtime so Waveshare must expose a separate user button on a free pin; confirm against the schematic. Fail-soft if mis-wired: input reads stuck-high and the task never fires. state_machine on AWAKE transition now calls local_screens_show_loading() right after display_wake() — so every wake (tap or POST /state) flashes a clear "Loading..." until the next /frame paints over it. app_main on boot: - Calls local_screens_init() after display_init(). - UNCONFIGURED → paint IP screen (replaces the M3 test pattern). - ASLEEP → backlight off (unchanged). - After all subsystems: button_init(). Build clean against ESP-IDF 5.4 (binary ~870 KB; the font/glyph data is under 800 bytes). TESTING.md M8 documents the visual checks, the BOOT-pin placeholder caveat, the AWAKE-overlay-overwrite behavior, the open follow-up about post-overlay backlight when ASLEEP, and the font fallback policy.
