2026-06-14M3 WIP: DSI bring-up + state machine + identity overlayLuke Hoersten1-3/+7
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.
2026-06-13M7: touch + outbound /state POST to ScryptedLuke Hoersten1-0/+123
state_client.{h,c}: - Worker task drains a depth-1 queue (xQueueOverwrite gives the replace-on-full semantics from the spec — in-flight POST is never cancelled; the next queued entry is overwritten by newer state). - esp_http_client POST to <scrypted>/state with Content-Type application/ json, User-Agent ScryptedViewport/<version>, Connection: close, 1s timeout. Body: {"viewport":"<name>","state":"wake"|"sleep"}. - Any non-2xx or transport error increments state_post_failures and is otherwise ignored. Silently drops if no Scrypted URL is configured. touch.{h,c}: - FT5426 capacitive touch on the shared I2C bus at 0x38. - 30ms polling task; tracks down/up transitions, detects taps as down-then-up within 500ms with a 150ms debounce. - On tap, toggles wake/sleep via state_machine_set_local(), which drives the local transition AND fires state_client_post() at Scrypted. state_machine adds state_machine_set_local(): runs the same transition as state_machine_set() then enqueues an outbound POST. Idle-timer expiry now uses this path so Scrypted sees idle-driven sleeps too (the spec's "tighten the race with /frame 409" path stays in place as the fallback). display.h exposes display_i2c_bus(); touch.c uses it instead of re-initializing the same I2C port. app_main starts state_client right after the state machine and starts touch after display init (touch is skipped if display isn't up since they share the bus). CMakeLists.txt: add esp_http_client to REQUIRES. Build clean against ESP-IDF 5.4 (binary ~860 KB; jumped ~210 KB from M6 because esp_http_client + cJSON path pulls in tcp_transport, mbedtls, http_parser). TESTING.md M7: flask-based test receiver, tap dispatch verification, failure-path check (kill receiver, confirm counter increments), queue-coalescing behavior, no-POST-on-Scrypted-initiated, no-POST- when-unconfigured.
