Neopixel-IR

This is a combined example code that does neopixel animations while listening for IR commands (given a capable enough chip)

It supports 6 different libraries, 2 for IR and 4 for Neopixels:

• https://github.com/z3t0/Arduino-IRremote
• https://github.com/markszabo/IRremoteESP8266/
• https://github.com/adafruit/Adafruit_NeoPixel
• https://github.com/FastLED/FastLED
• https://github.com/JoDaNl/esp8266_ws2812_i2s/
• https://github.com/MartyMacGyver/ESP32-Digital-RGB-LED-Drivers and it allows running neopixel animations on all 4 backends while using the same common code

ESP32 is now supported in FastLED, if you use ESP32 and FastLED, please see https://github.com/marcmerlin/FastLED-IR

Supported/tested chips are:

• basic AVRs like Uno/328p, Mega, Leonardo and so forth - they only allow concurrent IR if you remove interrupt disabling in the neopixel library, or you can update the neopixel strip and then listen for IR for a while.
• Teensy v3.1 - this allows talking to neopixels while listening for IR
• ESP8266 - also allows both thanks to esp8266_ws2812_i2s which doesn't tie up the CPU
• ESP32 - also allows both thanks to ESP32-Digital-RGB-LED-Drivers/RMT which also doesn't tie up the CPU.
