@andy31415 @woody-apple - is anything but the CLA holding back this PR? I can't do anything regarding the CLA because I have agreed to it, and other PRs went through....

@jagspaul yes, i2s does have DMA, and the needed bit rate (at least 2.8 Mhz to create proper ws28xx timing) is in the same ballpark as for 48kHz audio (1.5...

> Can I get 2K LED @20 Hz frame rate? That's the theoretical maximum, but there is some overhead (interrupt latency, bit packing restrictions into 64bit runs) that will reduce...

> some one has build I2S DMA driver on ESP32 chip. The principle is simple. What takes time in doing such a driver is understanding the details of the actual...

There is a strange problem in the "Darwin (no-ble-asan-clang)" test, see [test run here](https://github.com/project-chip/connectedhomeip/actions/runs/5842941864/job/15844587293?pr=28372): ``` INFO 314 | emAfEndpoints[index].dynamicAttributeStorage = dynamicAttributeStorage; INFO | ~~~~~~~~~~~~~~~~~~~~ ^ INFO ../../examples/chip-tool/third_party/connectedhomeip/src/app/util/attribute-storage.cpp:650:65: error: no member...

@bzbarsky-apple any idea why `Darwin (no-ble-asan-clang)` test fails despite correct ifdefs (details see comment above)? I can't make sense of this, why the `af-types.h` header should get processed with another...

@bzbarsky-apple: > and chip-tool compiles for me on Darwin using the commands CI is using.... ...which must be something else than just building chip-tool on Darwin directly as recommended in...

@bzbarsky-apple Uh-oh. Now clang-format insists on sorting the includes alphabetically, so **it simply reverts my attempt to get platform stuff included first** 😟 Now what? I understand that order of...

Why does `restyled`'s `clang-format` run render different results than running `clang-format --style=file` in the local project root? I verified that I use `clang-format` version installed by cpid (15.0.0) and that...
