NeoPixelBus_wrapper

NeoPixelBus_wrapper: A minimal wrapper to replace Adafruit_NeoPixel API to use Makuna's NeoPixelBus API.

(c) 2023, Ton Huisman for ESPEasy.

How to use

• Add this library to your lib folder
• Add the NeoPixelBus library to your lib folder
• Replace the #include <Adafruit_NeoPixel.h> line by #include <NeoPixelBus_wrapper.h>
• Replace your type Adafruit_NeoPixel variable(s) by type NeoPixelBus_wrapper variable(s)
• When using runtime instantiation of the wrapper object, replace your pixels = new Adafruit_NeoPixel(...) call by pixels = new NeoPixelBus_wrapper(...)
• Compile, and presto!

Limitations

• Currently only supports the most commonly used NeoPixel stripes NEO_GRB and NEO_GRBW, and the default NEO_KHZ800 method. (That's all what is used in ESPEasy...)
• When using an ESP8266 and the used GPIO pin is not GPIO2, you can enable # define NEOPIXEL_WRAPPER_USE_ADAFRUIT in NeoPixelBus_wrapper.h, but you'll then be using the Adafruit_NeoPixel library again, as that does allow to select the GPIO pin. The Adafruit_NeoPixel library then has to be available for compilation!
