• Now all NeoPattern objects are contained in NeoPatterns list.
• Now updateOrRedraw() does never call show().
• New pattern FLASH.
• Renamed ColorSet() to setColor().

Renamed 3 file from *.cpp to *.hpp. Added support for brightness.

• Enabled individual selection of patterns to save program memory.
• Renamed NeoPatterns.cpp, MatrixNeoPatterns.cpp and MatrixSnake.cpp to NeoPatterns.hpp, MatrixNeoPatterns.hpp and MatrixSnake.hpp.
• Renamed matrix pattern macros from PATTERN_* to MATRIX_PATTERN_*.

• Improved Fire cooling.

Changed TickerUpdate() and loadPicture() and their callers

• Changed TickerUpdate() and loadPicture() and their callers to achieve that YOffset is consistent with Y direction and origin.
• Removed restriction to 8 columns for FireMatrix pattern.

Fixed bugs if rows are not equal columns. Fixed bug in MatrixNeoPatterns constructor.

• Fixed bugs if rows are not equal columns.
• Fixed bug in MatrixNeoPatterns constructor.
• Added SUPPORT_ONLY_DEFAULT_GEOMETRY compile option.

• Fixed bugs if rows are not equal columns.
• Fixed bug in MatrixNeoPatterns constructor.
• Added SUPPORT_ONLY_DEFAULT_GEOMETRY compile option.

Removed blocking wait for ATmega32U4 Serial in examples

2.2.1

version 2.2.1

Added RGBW support, *D and other functions

• Added support for RGBW patterns. Requires additional 200 bytes for the AllPatternsOnMultiDevices example. Commenting out #define SUPPORT_RGBW or defining DO_NOT_SUPPORT_RGBW saves 400 bytes FLASH for the AllPatternsOnMultiDevices example.
• Use type Print * instead of Stream *.
• Changed function addPixelColor().
• Added function NeoPixel::printInfo(aSerial).
• Added *D functions, which take the duration of the whole pattern as argument.
• Added OpenLedRace example.
• Added empty constructor and init() functions.
• Added function updateAllPartialPatterns().

ESP versions

• Ported to ESP8266 and ESP32.
• Changed signature of NeoPatterns(NeoPixel * aUnderlyingNeoPixelObject). Swapped 4. and 5. parameter to make it consistent to the NeoPixel signature.
• Function setPixelOffsetForPartialNeoPixel() in NeoPixel.cpp added.
