- McpSettings was hardcoded to /data/service/mcp/settings.properties,
but ES3C28P uses storage.userDataLocation=SD so user data lives on
/sdcard/tactility/. Settings appeared to save but on reload returned
default false -> "enable and when I go back shows disabled".
Fixed to use getUserDataPath()+"/settings/mcp.properties" pattern
consistent with DisplaySettings/WebServerSettings, with
findOrCreateParentDirectory() and isFile() guard.
- HttpServer ctrl_port collision: ESP-IDF default 32768 used by both
WebServer (80) and DevelopmentService (6666). Second httpd_start()
failed silently -> dashboard up but /api/mcp 404 and :6666 refused.
Fixed with unique ctrl_port = 32768 + (port % 1000).
Added CONFIG_HTTPD_MAX_URI_HANDLERS=20 (default 8 < 9 needed for
7 handlers + 2 internal).
- DevService stack 5120 -> 8192 for /app/install handling.
- McpSystem video stream task stack 4096 -> 8192 and idle yield 50ms
(was 5ms always) to avoid CPU starvation blocking httpd tasks.
On RLCD, timer must always run: DisplayIdle early return on
!supportsBacklightDuty() broke MCP manual activation (cachedSettings
not loaded, backlight duty 0). Fixed to always load settings +
start timer, log RLCD detection, guard setBacklightDuty with
supportsBacklightDuty() and fallback duty 255.
- DisplaySettings: add disableScreensaverWhenCharging bool, persisted,
with UI toggle in Display app (Settings->Display) using
PowerDevice::IsCharging check via findDevices callback.
When charging and flag enabled, screensaver activation skipped,
and if already dimmed, wake on charging.
- ES3C28P Power driver: GPIO9 ADC1_CH8 2x divider 2500-4200mV spec from
~/Downloads official docs, TP4054 CHRG not connected to GPIO, so
IsCharging inferred via voltage thresholds (<500mV no battery USB
or >5000mV wall powered, >=4150mV high) + rising trend.
Verified: flashed es3c28p to /dev/cu.usbmodem101 (192.168.68.113),
WiFi FamReynaMesh RSSI -59, dashboard 200, :6666/info now works,
/api/mcp returns disabled correctly until enabled, persists to SD.
- Add ScreensaverType::McpScreen to DisplaySettings enum, toString/fromString
- Add 'MCP Screen' option to the Display settings screensaver dropdown
- New McpScreensaver (Screensaver subclass): creates full-screen lv_canvas on
the overlay, allocates framebuffer in SPIRAM, registers canvas pointer in
McpSystemState, shows 'Waiting for LLM...' until first draw command arrives
- Wire McpScreensaver into DisplayIdle::activateScreensaver() switch
- McpSystem::ensureOverrideScreen() now calls displayidle::findService()->
startScreensaver() instead of launching McpOverrideApp — canvas appears
automatically on any LLM draw command
- Remove McpOverrideApp (replaced by screensaver), deregister from Tactility.cpp
- Remove mcpOverrideEnabled from McpSettings — no longer needed
- Simplify McpSettingsApp: remove Screen Override toggle, update info text to
direct users to Settings -> Display -> Screensaver -> MCP Screen
- Add McpSettings (load/save mcpEnabled, mcpOverrideEnabled to /data/service/mcp/settings.properties)
- Add McpSystem: global state, canvas drawing (RGB565, BMP, PBM, text), I2S audio (WAV, MP3 via minimp3, tone, record)
- Add McpHandler: unauthenticated POST /api/mcp (JSON-RPC 2.0, 13 tools) and POST /api/screen/raw endpoints
- Route MCP endpoints before Basic Auth check in WebServerService::handleApiPost
- Start HTTP server at boot if either webServerEnabled OR mcpEnabled is set
- Fix setEnabled: start unconditionally when called with true; only stop if both WS and MCP are disabled
- Add McpSettingsApp (Settings category): toggle MCP service + screen override, show live endpoint URL
- Add McpOverrideApp (appId one.tactility.mcpscreen): full-screen LVGL canvas for LLM-driven display override
- Register both new apps in Tactility.cpp
