Suggested reviewers: Merge Risk: 🟡 Moderate · up to LED settings saves can stall if an output remains busy, and the Core2 diagnostic probe may disrupt I²C devices.

Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new recovery gesture can expose an offline device over Wi-Fi, and an interrupted LED-settings save may leave its outputs suspended.

rmt_target/LCD header patch logic so that an existing sibling LCD header with
invalid content raises an incompatibility error instead of searching other
dependency directories. Ensure both patches remain within the same NeoPixelBus
package, while preserving fallback behavior only when the sibling header does
not exist.

- Around line 890-896: Add a bounded timeout to the BLACK-frame confirmation
stage around the LED reinitialization state machine, using the existing
LED_REINIT_OFF_CONFIRM_TIMEOUT_MS pattern; when it expires, emit a warning and
continue so doInitBusses and configNeedsWrite are cleared and the reboot gate
cannot remain stalled. In wled00/wled.cpp line 250, verify the existing cleanup
path requires no direct change and that both flags clear after the timeout.

handleTouchbuilds the context from the class member at Line 1702. The header comment inM5StackDisplayTouchContext.hstates that the contexts prepare a later extraction. After that extraction the two access paths would diverge silently.Rename the local reference, for example to

@DedeHai @willmmiles this seems to be the "core" of the suggested NPB patch. What do you think? Is there something we can learn from it?
There was a problem hiding this comment.
It's not a new idea to me, at least. The S3 can feed a single RMT from a DMA engine with IDF >5, which will not be subject to the interrupt latency problems the tiny buffers give. The trouble (as always) is resource management -- this patch limits you to only one RMT channel at a time. I'm not 100% sure the IDF driver behaviour: either it will fail to initialize any other channels, or it will force them to operate in sequence (eg. channel 2 needs to wait for channel 1 to complete before it even starts).
@ToshihiroMakuuchi In any event, patching open source libraries at build time is unacceptable. If you think your contributions are valid and necessary, you should fork the NeoPixelBus repo and PR your contributions upstream. You can point your environments at your fork while you go through the upstream PR process to keep working in the mean time.

@ToshihiroMakuuchi thanks for your effort, the audio reactive part looks better now, and I think we are getting into a good status soon.

-
undo the whitespace change in audio_source.h https://github.com/wled/WLED/pull/5833/changes#r4034323808

- Around line 199-207: Update IsReadyToUpdate() to report ready when RMT
allocation failed, but otherwise return whether the active transfer has
completed using a nonblocking readiness check. Do not return true
unconditionally, so callers continue to wait or skip work while a transfer is

Avoid repeated touch initialization after a failed setup.
When CoreS3TouchGlobalWire::init() fails after prepareTouchHardware() completes, _inited remains false. Each wake-touch poll then calls display.getTouch(), which retries init() and can block for 360 ms on every poll.
Return immediately when _inited is false:

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
The Core2 diagnostic probe opens a second I2C bus on GPIO21/22 without PinManager ownership.
runDiagnostics() creates TwoWire probeWire( 1 ) on CORE2_INTERNAL_I2C_SDA / CORE2_INTERNAL_I2C_SCL, which are GPIO21 and GPIO22. It then calls probeWire.end().
- The code does not allocate GPIO21 or GPIO22 through
PinManager. - On Core2, GPIO21/22 is the internal I2C bus. WLED's global
Wire/ I2C0 is normally set up on the same pins. probeWire.begin()sends the SDA/SCL signals to I2C1 through the GPIO matrix.probeWire.end()then disconnects them.- After that, global
Wire/ I2C0 is no longer connected to those pins. Any later global-bus access on Core2 fails until the pins are set up again.
This also goes against the PR's stated design that internal devices use WLED's global Wire and no second controller is created.
Fix: when i2c_sda == 21 && i2c_scl == 22, run the probe on global Wire. Otherwise, allocate the pins with PinManager::allocateMultiplePins() before the probe, and release them with deallocatePin() after it.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not resume the strip when a safe-shutdown cancel overlaps an LED settings save.
serviceLedSettingsSaveGuard() waits in BLACK_PENDING while safeShutdownBlankActive is true. The reverse overlap has no guard.
The failing sequence:
- A settings save reaches
BLACK_READY,REBOOT_ARM_PENDING, orWAIT_REBOOT. The old bus is suspended at this point. - The user holds the power key.
beginSafeShutdownBlank()runs. - The user releases the key.
cancelSafeShutdownBlank()callsstrip.resume()andstrip.show()on the old bus.
After step 3, the old bus drives output again while serveSettings() or the pending bus rebuild still uses the old configuration. This breaks the guarantee that the old bus stays BLACK and suspended during the save.
Keep the strip suspended during a cancel while a save is in progress.

calling strip.resume() from a usermod invites for trouble, unless the UM also acquired the lock with strip.suspend().
strip.resume() removes the lock that should prevent effects from running while segment configuration changes are ongoing. If an effect is active while the Webserver task (async_tcp) changes the configuration, this will most likely lead to a crash.

@willmmiles This looks like a hack, and it appears to be for the "blank all LEDs before bus re-init" workaround. What do you think?

@ToshihiroMakuuchi I have already asked (3 times) if this LEDs blanking workaround is specific for the coreS3 board. We need an answer.
@coderabbitai please verify if this statement is true for all files in this PR. |

Summary
This PR adds community support for running WLED on the M5Stack CoreS3.
The implementation keeps CoreS3-specific functionality in usermods and build scripts without requiring direct changes to the WLED core.
Features
CoreS3 I2C integration
CoreS3 internal I2C devices use WLED's global
Wire/ I2C0 bus on:The previous M5GFX/lgfx
I2C_NUM_1access path has been removed from the CoreS3 display, power, and ES7210 integration.The CoreS3 display hardware backend accesses the internal I2C devices through the existing global WLED
Wirebus without starting a second I2C controller on the same physical pins.ESP32-S3 LED stability
The CoreS3 build applies NeoPixelBus compatibility/stability handling through a PlatformIO pre-script:
The patch is applied automatically during dependency preparation and is designed to be idempotent.
On the currently validated ESP32-S3 / ESP-IDF / NeoPixelBus stack, multiple DMA-backed RMT outputs may exhaust the available RMT TX channel resources.
The failed-channel guard prevents an RMT initialization failure from permanently blocking WLED bus teardown/reinitialization.
For the validated three-output CoreS3 configuration, Port A / B / C are configured with the I2S driver.
Build
A CoreS3 PlatformIO configuration example is included at:
usermods/CoreS3_Display/platformio_override.ini.sampleThe CoreS3 display usermod declares the required M5GFX dependency using the M5GFX 0.2.26 Git tag for reproducible clean builds.
WLED core integration
The current CoreS3 implementation is contained in usermods and build scripts.
No direct WLED core source-file modification is required by the current PR state.
Validation
Tested on a physical M5Stack CoreS3 with ESP32-S3.
Validated on the current upstream
main-derived baseline with a full clean dependency rebuild.Test coverage included:
The final three-output I2S regression completed without the previous
gdma: peripheral 5 is already used by another channelfailure.RMT allocation failure behavior was also tested, and the failed-channel guard prevented it from blocking WLED runtime bus reinitialization.
Documentation
Detailed English and Japanese documentation is included under:
usermods/CoreS3_Display/This is a community implementation and is not official M5Stack firmware.
