NOTE: Due to the varied board layouts for Esp8266, even though the pin maybe exposed, it may not be usable due to some custom feature on the board you use. If you find it not working, you should review the hardware schematic of your board and confirm the pin is not used for other purposes that interferes with it being used for NeoPixelBus.
This method uses the CPU to manage a small hardware managed UART buffer to send the data to the NeoPixels. Thus it requires more CPU overhead than the Dma method but it does NOT require an extra buffer. Its main benefit is that it is usable on ESP-01.

This method uses the UART interrupt to read from a secondary buffer to send the data to the NeoPixels. It requires very little CPU overhead but does require an extra buffer similar to the Dma method. Its main benefit is that it is usable on ESP-01 or other projects where the pin used by the DMA method is not available.
