  637. // them out in the common code, they are defined to no-op. This allows the code to compile

  638. // (which it wouldn't otherwise) but irsend will not work until ESP32 specific code is written

  642. // wrong length. This is specifically an issue for neopixels which require 800Khz resolution.
