 ## [Spiral Topography](https://github.com/Makuna/NeoPixelBus/wiki/Spiral-Topography)
-The included topography system assumes a Cartesian coordinate system.  This doesn't help if you use concentric rings of NeoPixels. This section will talk about how to implement a spiral topography that will replace the current topography and work within the design goals of this library.

+## [ESP32 and RTOS Tasks](https://github.com/Makuna/NeoPixelBus/wiki/ESP32-and-RTOS-Tasks)
+On ESP32, when the CPU is loaded, asynchronous WiFi libraries (like ESPAsyncWebServer or async-mqtt-client) may interfere with interrupts used to control the LEDs (I2S mode is less affected by this), which causes flickering of LEDs. This topic describes a way to solve that.
