12-OBD-Speed: battery voltage arc and idle/screen-off mode

- ATRV every 2 s; voltage arc in the bottom gap (11-15 V) + number,
  colored by state (low / weak / resting / charging / overcharge)
- idle after Off/2/5/10 min without speed data (settings page, NVS):
  screen off, GIF paused, OBD polling stopped, ATRV every 30 s;
  wakes on touch (swallowed by a top-layer overlay) or > 13.2 V
- status pill moved up to make room for the voltage

+# GIF tests
+
+GIF playback experiments on the JC3636W518 (originally part of the 2024 OBD display attempt; renamed 2026-10-23).
+Used to find the fastest GIF setup — results are in `../shared/README.md` and `../CLAUDE.md`.
+
+## Projects (PlatformIO, LVGL 9.6.0, shared library in `../shared`)
+| Folder | What it does |
+|---|---|
+| `display_gif_embedded/` | `loligod.gif` compiled into firmware (`src/loligod.c`, 2.2 MB GIF → 3.5 MB firmware, `default_16MB.csv`). Plays at full GIF speed (~23.8 fps, 53 % CPU). Starts without SD card. |
+| `display_gif_sd/` | `wallpaper.gif` from the SD card, loaded into PSRAM once and played from memory (~15 fps for the current file). |
+| `assets/gifs/` | GIF files (`dump/` = unused collection) |
+
+## Build / upload
+```
+pio run -d display_gif_embedded -t upload       # flash (COM21)
+pio device monitor -d display_gif_embedded      # serial: FPS / refresh / other / CPU once per second
+```
+(`pio` = `%USERPROFILE%\.platformio\penv\Scripts\pio.exe` if not on PATH.)
+
+## Notes
+- `display_gif_embedded/src/montserrat_100.c` (100 px digits font, 1 bpp) is present but not used.
+- `display_gif_sd` returns early in `setup()` if the SD card fails to mount (black screen).

-# OBD Display (2024 experiments)
-
-Earlier attempt to show car speed from an ELM327 OBD-II adapter on the JC3636W518.
-Because the ESP32-S3 has no Bluetooth Classic, the design used a second (classic) ESP32 as a bridge:
-
-```
-ELM327 --(BT Classic SPP)--> classic ESP32 (elm327_wifi_bridge) --(WiFi AP, HTTP /speed)--> JC3636W518 (display_speed_wifi)
-```
-
-Split out of `2-Program Example/Demo_Arduino/ST77916_LVGL_DEMO/` on 2026-10-22 and converted to PlatformIO. History is in git.
-
-## Projects (all PlatformIO)
-| Folder | Runs on | What it does | Was |
-|---|---|---|---|
-| `display_speed_wifi/` | JC3636W518 | GIF background from SD (`A:wallpaper.gif`) + joins AP `ESP32-Access-Point`, polls `http://192.168.4.1/speed`, shows it in a label | `ST77916_LVGL_DEMO/8.4/` |
-| `display_gif_sd/` | JC3636W518 | GIF from SD (`A:wallpaper.gif`) + static text label | `ST77916_LVGL_DEMO/working version/` |
-| `display_gif_embedded/` | JC3636W518 | GIF compiled into firmware (`src/loligod.c`, 2.2 MB GIF → 3.4 MB firmware, uses `default_16MB.csv` with 6.25 MB app slots). **LVGL 9.6.0**, plays at full GIF speed (~23.4 fps), prints FPS once per second. GIF starts without SD card. WiFi code commented out. | `ST77916_LVGL_DEMO/` (top level) |
-| `elm327_wifi_bridge/` | **classic ESP32** (not S3) | BT Classic → ELM327 named `OBDII` (PIN 1234), WiFi AP `ESP32-Access-Point` / `123456789`, serves `/speed` (kph) | `ST77916_LVGL_DEMO/esp23_elm327_to_wifi/` |
-| `elmulator/` | classic ESP32 | Fake ELM327 for testing without a car. Library in `lib/ELMulator`, envs `simple`, `custom`, `wifi` (BT name `OBDII`) | `ST77916_LVGL_DEMO/ELMulator-master/` |

-## Build / upload
-Open a project folder in VS Code with the PlatformIO extension, or from a terminal:
-```
-pio run -d display_speed_wifi                 # build
-pio run -d display_speed_wifi -t upload       # flash (COM21)
-pio device monitor -d display_speed_wifi      # serial monitor
-pio run -d elmulator -e wifi -t upload --upload-port COMxx
-```
-(`pio` = `%USERPROFILE%\.platformio\penv\Scripts\pio.exe` if not on PATH.)
-
-## Configuration
-- **JC3636W518 projects:** pioarduino platform `51.03.05` (= Arduino core 3.0.5), board `esp32-s3-devkitc-1` with 16 MB QIO flash, OPI PSRAM, `huge_app.csv` (3 MB app), USB-CDC on boot, COM21.
-  Libraries come from the vendor folder via `lib_extra_dirs = ../../2-Program Example/Demo_Arduino/library`.
-  Each project uses its **own `include/lv_conf.h`** (`-DLV_CONF_INCLUDE_SIMPLE -Iinclude`):
-  - `display_speed_wifi`: LVGL heap 4 MB in PSRAM (`ps_malloc`)
-  - `display_gif_sd`: LVGL heap 7 MB in PSRAM
-- **Classic ESP32 projects:** official `espressif32@6.10.0` (Arduino core 2.0.17), board `esp32dev`, `huge_app.csv`. Set `upload_port` to the classic ESP32's COM port.
-  Bridge libraries: `powerbroker2/ELMduino@3.4.1`, `esphome/ESPAsyncWebServer-esphome@3.4.0`.
-
-## Notes
-- `src/montserrat_100.c` (100 px digits font) is present but not referenced by any sketch yet.
-- SD-based GIFs use LVGL drive `A:` = `LV_USE_FS_FATFS` (reads through ESP-IDF FatFS on the SD_MMC mount). Not yet verified on hardware.

-# ELMulator
-
-## ODBII & ELM327 Emulation library
-
-This is a fork of the [GTTurboEcu library by TheBigBadWolfClub](https://github.com/TheBigBadWolfClub/GTTurboEcu) which is no longer being maintained. 
-
-I have updated the library with the following changes:
-- included fixes submitted to the upstream fork but never merged
-- updated the library to work with Bluetooth serial devices (like esp32)
-- added support for connecting via WiFi (default port 30000)
-- added additional functions to the emulator
-- optimized the use of String class for lower memory requirements
-- fixed a few bugs from earlier version
-- refactored many methods to simplify use of the library  
-- made it easier to add your own new functions with sample/test data
-- implemented a simple emulation mode that can be easily configured with just a few lines of code 
-- added new example programs to demonstrate use of the library 
-
-This library allows you to program a microcontroller device to emulate an ELM327 OBDII adapter connected to an ECU. The emulator can work with any of the huge number of ODBII apps that are compatible with the ELM327-standard adapters, like Torque or CarScanner. 
-
-There are two main use cases for this library:
-
-1. It is ideal for use in developing OBDII applications using the [ELMduino](https://github.com/PowerBroker2/ELMduino) library. You can build the example program, upload it to a $10 ESP32 device with builtin Bluetooth and use it for your testing and development, avoiding the need to be communicating with an actual ELM327 device plugged into a vehicle. (Doing app development sitting on a folding chair in the garage gets old pretty quickly...).
-
-2. This library can be used to as the building block for creating your own ELM327 compatible device that can read values from various custom sensors and allow you to monitor
-those sensors with your own software or one of the many OBDII client applcations that are compatible with the ELM327 specification. No connection to an actual OBDII port is needed. 
-
-## Platforms
-
-ELMulator is built and tested using the Arduino framework on a variety of ESP32 dev boards. The ESP32 platform is ideal as it has Bluetooth, Wifi and serial capability included and is very inexpensive. The library should work with any Arduino compatible device with the use of additional hardware like the [HC05 Bluetooth Module](https://components101.com/wireless/hc-05-bluetooth-module) to provide Bluetooth capability. 
-
-## Using ELMulator
-
-In order to take best advantage of this library, you should be familiar with two specifications:
-
-- The [OBDII protocol](https://en.wikipedia.org/wiki/OBD-II_PIDs)
-
-- The [ELM327 datasheet](https://www.elmelectronics.com/DSheets/ELM327DSH.pdf)
-
-You need to understand what a PID is and how it is defined (mode, pid, number of bytes, conversion formulas ...) and how to send/receive PID info from the ELM327 device.
-
-### Easily create an ELM327 emulator with just a few lines of code:
-
-```C
-#include "ESP32_Simple_ELMulator.h"
-
-/**
- * This example demonstrates a very simple implementation of ELMulator.
- * It handles all AT Commands, SUPPORTED_PIDS queries, etc. and rejectss unsupported requests.
- * All Mode 01 PID requests are provided a response of the correct data size with mock data values.
- * Typical use case is for testing custom applications to work with ELM327 devices. 
- */
-
-const String deviceName = "ELMULATOR"; // Bluetooth device name to use (no pin)
-ELMulator ELMulator;
-
-void setup()
-{
-    Serial.begin(115200);
-    Serial.println("Starting ELMulator...");
-    ELMulator.init(deviceName, true); // Initialize with support for all PIDs 0x00 to 0x65, providing mock data
-    ELMulator.begin();                // ELMulator will run continuously, listening for and respondng to requests
-}
-
-void loop() {}
-```
-
-That's it. Complile and install the program on an inexpensive ESP32 dev board and you can be running in a couple of minutes. You can connect your app or device to the Bluetooth device "ELMULATOR" and query it as though it were an ELM327 adapter connected to a vehicle. Very handy for testing, without the need to install and configure a physical adapter attached to an actual vehicle. 
-
-### Custom ELM327-compatible programs/devices
-
-You can also use ELMulator to provide custom responses to specific queries or as the basis for your own device that reads physical sensors and provides sensor data via the OBDII / ELM327 protocols. This example code shows responding to PID requests with hardcoded values, custom sensor data and mock sensor values to demonstrate some of the possibilities for creating your ELM327 compatible application or device. 
-
-```C
-#include "ESP32_Custom_ELMulator.h"
-
-const String deviceName = "ELMULATOR"; // Bluetooth device name to use (no pin)
-
-// Set up hardcoded responses to non-standard PID requests for MIL, DTC, ODO data
-const String milResponse = "4101830000";                       // MIL response code indicating 3 current DTC
-const String dtcResponse = "43010341\r\n43010123\r\n43010420"; // DTC response returning 3 DTC codes (multiline response)
-const uint32_t odoResponse = 1234567;                          // Hardcode an odometer reading of 1234567
-
-ELMulator ELMulator;
-
-void setup()
-{
-    Serial.begin(115200);
-    Serial.println("Starting ELMulator...");
-    ELMulator.init(deviceName); 
-
-    // Register the specific PIDs we are going to handle.
-    // ELMulator will respond to SUPPORTED_PIDS request ("0101") with the appropriate value
-    // indicating which PIDs it can respond to.
-    ELMulator.registerMode01Pid(ODOMETER);
-    ELMulator.registerMode01Pid(ENGINE_COOLANT_TEMP);

-## Using ELMulator with an addon Bluetooth module (GPIO)
-
-By default, ELMulator will work on an EPS32 with builtin Bluetooth, but you can configure another device type for use with a bluetooth module like the [HC05 Bluetooth Module](https://components101.com/wireless/hc-05-bluetooth-module) connected via GPIO and using SoftwareSerial.h library. To do so, the following two changes need to be made:
-
-1. Update definitions.h file and undefine or set to false "BLUETOOTH_BUILTIN":
-
-```
-// true == We are using hardware that has builtin Bluetooth
-// false == We are using hardware with a Bluetooth module attached via GPIO pins
-#define BLUETOOTH_BUILTIN true  
-```
-2. Provide the serial baud rate, Rx and Tx pin numbers when creating your ELMulator instance:
-
-```
-/**
-* When creating a new instance of ELMulator with an attached
-* BT module, we need to set the Bluetooth serial parameters
-*
-* @param baudRate - rate for bluetooth serial port (normally 9600)
-* @param rxPin - the Arduino RX pin for the Bluetooth module (serial port)
-* @param txPin - the Arduino TX pin for the Bluetooth module (serial port)
-* @return
-*/
-ELMulator(uint32_t baudRate, uint8_t rxPin, uint8_t txPin);
-```
-
-Other than that, use of the ELMulator library is the same as when using builtin Bluetooth.

+# OBD Speed (JC3636W518)
+
+Vehicle speed from an ELM327 over BLE, shown as a big number + arc gauge on top of an animated GIF.
+Uses the shared board library and LVGL 9.6 (`../shared`), NimBLE-Arduino 2.5.1.
+
+## Use
+- **Speed page** — speed in km/h (`--` = no data: not connected, or ignition off), arc gauge 0–200 km/h,
+  status pill below the number (adapter name when running, otherwise what it is doing).
+  **Battery voltage** (`ATRV`, every 2 s) as a small arc in the bottom gap (11–15 V) + number; color:
+  red < 11.8 V, orange < 12.2 V, green < 13.0 V (resting OK), blue ≤ 14.8 V (charging), red above (overcharge).
+- **Swipe left → adapter menu** — scans while open. OBD-like adapters (name OBD/ELM/…, or service FFF0/FFE0/18F0)
+  are listed first in green. **Tap one** to select it: it is remembered (NVS) and connected immediately.
+  **Forget** clears the remembered adapter, **Done** (or swipe right) returns to the speed page.
+- **Swipe left again → settings** — screen rotation 0 / 90 / 180 / 270 degrees, and **screen off without data** Off / 2 / 5 / 10 min (default 2). Both remembered in NVS.
+- **Idle** — after that time without speed data (ignition off, adapter gone) the screen goes dark, the GIF pauses and
+  OBD polling stops; only `ATRV` every 30 s (answered by the adapter itself, doesn't wake the car's bus).
+  Wakes on a touch (the touch is swallowed) or by itself when the voltage rises above 13.2 V (engine started).
+  Not used while no adapter is chosen.
+- On power-up the remembered adapter is connected automatically; if the link drops or the adapter is not
+  there (car off), it retries every 3 s. With no adapter remembered, the device starts on the menu page.
+
+## How it talks to the ELM327
+Service `FFF0`, notifications + commands on `FFF1` (verified with the user's "OBDII" adapter, see
+`docs/2026-10-23_ble_scanner_car_test.txt`, made with the BLE scanner tool that was removed afterwards — in git history); other adapters: first notify+write pair.
+Init: `ATZ`, `ATE0`, `ATL0`, `ATS0`, `ATH0`, `ATSP0`, `0100`; then `010D` (speed) is polled continuously.
+Serial (115200) prints status changes as `[obd] ...`.
+

 ## Gotchas / observations
-- **LVGL GIF bug (patched locally):** LVGL 8.3.11 `gifdec.c` (`gd_open_gif`) filled the canvas *opaque* with the GIF's background color. GIFs with a transparent background (e.g. `loligod.gif`, bg = RGB 28,29,49) showed that dark gray except where "restore to background" frames had cleared to transparent (→ screen black). **Patched** in the vendor copy `2-Program Example/Demo_Arduino/library/lvgl/src/extra/libs/gif/gifdec.c`: initial canvas alpha 0x00 (marked `LOCAL PATCH`). Re-apply if LVGL is ever replaced/upgraded.

Re-apply if LVGL is ever replaced/upgraded.
 - Most GIFs in `assets/gifs` are optimized (transparent unchanged pixels, disposal 1/2); `loligod.gif` has a fully transparent background (~84 % of each frame).
 - **GIF performance** (360×360 loligod, embedded, measured with a `monitor_cb` FPS counter in `display_gif_embedded`):
   baseline 15.4 fps (decode 27 ms + refresh 31 ms) → no LVGL log / no per-loop prints: no change → `vTaskDelay(1)`: 16.5 → **double draw buffer** (2×72 rows internal RAM): 19.5 (refresh 21 ms) → **`-O2`** instead of `-Os`: **20.6 fps** (refresh 19 ms, decode ~24 ms).

 - **SD card (user's 487 MB SDSC)** intermittently fails to init (`sdmmc_init_ocr ... 0x107`) after resets; once stuck only a power cycle helps (card VDD is hard-wired to 3V3). Recommend a newer SDHC card.
 - Reading boot logs: USB-CDC — reset via DTR=0/RTS pulse, then reopen the port (it re-enumerates).
 - **LVGL 9.6.0 port** (`display_gif_embedded`, 2026-10-23): **23.4 fps** (= the GIF's own 23.7 fps; decode ~12 ms, refresh ~24 ms) vs 20.6 fps tuned LVGL 8.3. LVGL 9.6 replaced gifdec with bitbank2 AnimatedGIF (2× faster decode, correct transparency — no local patch needed).

No effect: `LV_GIF_CACHE_DECODE_DATA` (not used anywhere in 9.6), 120-row buffers. AnimatedGIF "turbo" mode can't be used: it only outputs in COOKED draw mode, LVGL uses RAW.
+- **All JC3636W518 LVGL projects now use LVGL 9.6.0 + the shared library** (10-GIF-Tests/*, 12-OBD-Speed). SD drive `A:` = `LV_USE_FS_STDIO` on `/sdcard/`.
+- 80 MHz QSPI and RGB565_SWAPPED rendering: **visually confirmed OK by the user** (colors correct, no glitches).
 - Display is round: corners of the 360×360 framebuffer are not visible — design UI within a 360 px circle.
 - Compiling a 13.9 MB GIF into the firmware will not fit "Huge APP" (3 MB); large media should live on SD (or in a custom partition).
-- The top-level demo `setup()` returns early if no SD card is present, before showing anything.
+- `display_gif_sd` `setup()` returns early if the SD card fails to mount (black screen); `display_gif_embedded` starts its GIF first.
 - Draw buffer is in internal RAM; PSRAM is available for larger buffers / images.
+- **LittleFS** works on the `spiffs` partition of `huge_app.csv` (~900 KB); the first mount after flashing formats it (prints `Corrupted dir pair` / `mount failed (-84)` and some `task_wdt ... task not found` once — harmless).
+- BLE (NimBLE) in the user's home: ~12 devices visible within 10 s.
+- Big fonts: generate with `npx lv_font_conv` (Node 22 installed) from `lvgl/scripts/generators/built_in_font/Montserrat-Medium.ttf`; `-DLV_LVGL_H_INCLUDE_SIMPLE` (in shared ini) makes the generated `#include` work.
+- Binary assets (GIFs): `board_build.embed_files = data/x.gif` → `extern const uint8_t x_start[] asm("_binary_data_x_gif_start")` (no huge C arrays).
+- Python edit scripts: never pass C strings containing `\n` through a bash heredoc into Python — it turned into a real line break twice; write the script with the Write tool instead.
+- Serial output from the background task (core 0) is often lost, not only right after reset; don't rely on it as proof. Serial output right after a reset can be lost/garbled (USB-CDC re-enumeration, prints from two cores interleave) — don't conclude a task isn't running from a missing early line.
+- `Preferences` prints `nvs_open failed: NOT_FOUND` the first time a namespace is read before it was written — harmless.

+| `LV_COLOR_FORMAT_DEFAULT = RGB565_SWAPPED` | renders in the ST77916 byte order → no swap pass in flush |
+| QSPI 80 MHz (was 50) | faster transfer to the panel |
+| `-O2`, IRAM for hot LVGL functions | faster rendering/decoding |
+| GIF in display color format (`lv_gif_set_color_format`) | per sketch, only when the GIF needs no transparency (plain background) |
+
+Result: CPU for the GIF 86 % → 53 % at full frame rate.
+
+## Display / LVGL facts
+- Display format is `RGB565_SWAPPED`. For images/canvases you create yourself, use `lv_display_get_color_format(disp)` or ARGB8888 when transparency is needed.
+- LVGL drive `A:` = SD card (`LV_USE_FS_STDIO`, path `/sdcard/`); mount the card with `SD_MMC` first.
+- `LV_USE_STDLIB_MALLOC = CLIB`: LVGL uses `malloc`, so large allocations land in PSRAM. `lv_mem_monitor()` reports 0 in this mode.
