🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Keep both patches in the same NeoPixelBus package.
If the sibling LCD header exists but fails the content check, Line 167 searches every dependency directory. That search can select an LCD header from a different package than rmt_target. The active LCD header can then miss the GDMA teardown patch and fail a later LED-bus rebuild. Raise an incompatibility error when an existing sibling does not match instead of falling back globally.

This seems to be a patch for a temporary situation. NeoPixelBus has known issues in esp-idf v5.x builds. If the patch suggested here is generic (= not specific for the "M5Stack Core3" board) then it's better to make a PR in upstream NeoPixelBus.
Furthermore we plan to replace Neopixelbus with our own code in the near future, see #5704.

@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.

The ES7210 datasheet specifies 8–48 kHz in single-speed mode. The existing That clock ratio is supported by the ES7210. Do not change the CoreS3 path to The ES7210 is configured as a two-slot standard-I2S source. The current CoreS3 source uses: _config.channel_format = I2S_CHANNEL_FMT_RIGHT_LEFT;
i2s_set_clk(..., I2S_CHANNEL_STEREO);This preserves the 16-bit left/right frame structure that the codec expects. The safe configuration is:
For example, the existing conversion in const int32_t left = stereoSamples[i * 2U];
const float mono = left * _sampleScale;This gives AudioReactive one mono sample per frame, like the other audio sources. The current implementation already has this external mono behavior. It currently creates the mono sample by averaging MIC1 and MIC2. For 22.05 kHz, also remove the CoreS3-only 16 kHz configuration in
The ES7210 I2C register table does not need a sample-rate-specific change for this case. Registers I recommend a hardware test before replacing the validated 16 kHz profile. Check:

@ToshihiroMakuuchi I'm still wondering if this this "deferred bus re-init" should be discussed in a separate PR. My understanding is you want to ensure that all LEDs are switched to "black" when users re-size their led output in settings.
Is this a problem that only affects the Core S3 board?

@softhack007, presetBootTargetName is an Arduino String, declared in usermods/CoreS3_Display/CoreS3_Display.cpp at Line 434:
String presetBootTargetName = "NONE";"NONE" is a string literal of type const char[5]. The assignment uses String::operator= to copy its contents into presetBootTargetName.
This assignment does not cause a memory leak. The String object owns its internal buffer and releases or replaces the previous buffer as needed.
Repeated dynamic String assignments can contribute to heap fragmentation on embedded targets. That is a separate risk from a leak. This specific reset to the short constant "NONE" is low risk, but the surrounding repeated assignments from preset names use dynamic allocation.

Initialize the CoreS3 I2C1 bus independently of display runtime.
When WLED_M5STACK_CORES3 uses a Core2-family WLED_M5STACK_DISPLAY_PROFILE, CoreS3_Display runs temporary diagnostics and returns before display.begin(). CoreS3_Power also defers its M5GFX I2C1 work until that bus is active. AudioReactive case 7 can therefore fail on its first I2C_NUM_1 transaction, causing ES7210 and I2S initialization to stop.
Usermod registration order is not stable because all registrations use linker section 00001. It cannot fix this path: the display setup still skips display.begin() when it runs first, and AudioReactive can write before it when it runs first.
Initialize the shared M5GFX I2C_NUM_1 bus in the CoreS3 setup boundary before profile-specific early returns, then reuse it for display and ES7210 access.

Do not bypass shrink handling when all physical buses are removed.
When targetPhysical == 0, this return skips pendingConfigShrinksAnyPhysicalBus(). If the user removes the final physical bus, finalizeInit() destroys the old bus before it sends BLACK. The connected LEDs can retain their last color.
Remove the targetPhysical == 0 condition.
Proposed fix

- oldPhysical == 0 ||
- targetPhysical == 0

) {Based on learnings, LEDs beyond a reduced bus retain their latched state until the old bus sends BLACK.

Add an overall deadline for output-idle deferral.
waitForLedOutputIdle() bounds one attempt only. If BusManager::canAllShow() remains false, each loop returns here with ledShrinkSaveState == WAIT_OFF. deferBusReinit() then remains true indefinitely. This blocks the bus rebuild, configuration write, and queued reboot.
Track one deadline across attempts. On expiry, use a safe recovery path that does not destroy an active bus, such as canceling the rebuild or requesting a controlled restart.

In `@usermods/CoreS3_Power/CoreS3_Power.cpp` around lines 876 - 879, Update the
LED reinitialization deferral flow around waitForLedOutputIdle() and
deferBusReinit() to track a single overall deadline across repeated attempts,
rather than resetting the wait on each loop. When the deadline expires, invoke a
safe recovery path that preserves any active bus, such as canceling the rebuild
or requesting a controlled restart, so configuration persistence and queued
reboot are not blocked indefinitely.

@coderabbitai I disagree with your recommended direction in #5833 (comment). It does not make much sense to add es7210 support but limit it to "this only works on the coreS3". |
|
Tip For best results, initiate chat on the files or code changes.
A generic ES7210 AudioReactive source is useful. The implementation should separate these concerns:
The CoreS3 should provide a tested board configuration. It should not define the functional scope of the ES7210 source. The remaining technical issue is the IDF 4.4 API difference. 🐇 ✏️ Learnings added

@coderabbitai is it technically necessary to use I2C_NUM_1 in this PR? Maybe its better to use I2C unit 0 - this unit can also utilize any pins, and wled already initializes the driver when global I2C pins are set. |

The ES7210 has no dependency on an ESP32 I2C controller number. It only requires an I2C bus on the selected SDA and SCL pins. The current
The code comments confirm that M5GFX initializes Using two I2C controller drivers on the same SDA and SCL pins is not a valid steady-state design. A second controller does not provide a separate physical bus when it uses the same pins. I agree with the proposed direction. The CoreS3 internal bus should use WLED global I2C, that is This refactor must also configure M5GFX to use the existing global bus, or prevent M5GFX from independently initializing

Summary
This PR adds community support for running WLED on the M5Stack CoreS3.
The implementation keeps CoreS3-specific functionality in usermods and build scripts as much as possible, with only a minimal integration hook in the WLED core.
Features
ESP32-S3 LED stability
The CoreS3 build applies two NeoPixelBus compatibility/stability patches through PlatformIO pre-scripts:
These patches are applied automatically during dependency preparation and are designed to be idempotent.
Build
A CoreS3 PlatformIO configuration example is included at:
usermods/CoreS3_Display/platformio_override.ini.exampleThe CoreS3 usermods declare the required M5GFX dependency using the M5GFX 0.2.26 Git tag for reproducible clean builds.
WLED core integration
The CoreS3 implementation is kept outside the WLED core wherever practical.
The only direct WLED core integration is a small weak hook used to defer the standard LED bus reinitialization when the CoreS3 power usermod needs to perform its guarded bus rebuild sequence.
Without the CoreS3 usermod, the default WLED behavior is unchanged.
Validation
Tested on a physical M5Stack CoreS3 with ESP32-S3.
Validated on the current upstream
mainbaseline with a full clean dependency rebuild.Test coverage included:
No panic, watchdog, RMT, or GDMA errors were observed during the final hardware regression.
Documentation
Detailed English and Japanese documentation is included under:
usermods/CoreS3_Display/This is a community implementation and is not official M5Stack firmware.
