v1.2.8

[1.2.8] (2021-03-19)

Fixed

• Matrix effect: fixed wrong index boundary.

Changed

• Spectrum effect: reimplemented using band peak detectors.
• State: merged distinct slowRotatingHue and fastRotatingHue into a rotatingHue.
• Blackout effect: forced strip clearing at every loop.

Added

• AudioChannel: implemented individual peak, peakSmooth, peakHold and peakDetected for 16 frequency bands.
• Controller: implemented confugurable stats and standby timers.
• VU2 effect: implemented configurable color.
• Scroller effect: implemented audio-reactive choking.

v1.2.7

Fixed

• Fixed examples.

Changed

• Allowed addFx() method to add up to 9 effect.

v1.2.6

Changed

• Moved Strip implementations code to src/strip directory. This change requires updating the #include directives in your stage implementation for any subclass of Strip (e.g. #include "PhysicalStrip.h" becomes #include "strip/PhysicalStrip.h", etc.)
• Changed from FFT256 to FFT1024.
• Reimplemented Scroller using dominant frequency information.
• Reimplemented Spectrum using FFT bands instead of FFT bins.

Added

• Implemented FFT bands and dominant band.
• Implemented EllipticMotion class for implementing 2D effects based on rotating objects.
• Implemented Spiral effect.

v1.2.5

Fixed

• Fixed Fx flush method.

Changed

• Replaced Strip method void sanitize(int16_t &indexFrom, int16_t &indexTo) with bool crop(int16_t &indexFrom, int16_t &indexTo), which restricts the given range into the visible range only when the given range overlaps with the visible range. In that case it returns true, otherwise false.

v1.2.4

Added

• Adopted Keep a Changelog.

v1.2.3

Changed

• Replaced cryptic PCB connector labels (J1, J2, J3, etc.) with more human-frendly ones (POWER, LEDS, IR-RECV, etc).

v1.2.2

Fixed

• Fixed various bugs triggered by corner cases, especially when using JoinedStrip.
• Fixed a bug in HarmonicMotion caused by a wrong assignment.

Added

• Multiplex
  • Increased the number of multiplexed effects to 9.
• HarmonicMotion
  • Added methods for random positioning:
    • setFixedPointRandomPosition()
    • setRandomPosition()
• Implemented new simple effect Bounce.

v1.2.1

Fixed

• JoinedStrip
  • Fixed various bugs.

v1.2.0

Changed

• AudioChannel
  • Method trigger has been removed and its functionality is now provided by AudioTrigger.
• Trigger
  • Replaced by AudioTrigger.

Fixed

• Strip
  • Fixed paintNormalizedSize method.
• JoinedStrip
  • Fixed paint method when indexFrom falls in strip 1 and indexTo falls in strip 2.
  • Gap has been replaced with a StatefulStrip, so that its behavior is consistent with the visible portion of the strip.

Added

• Strip
  • Implemented buffered method for creating a buffered version of a Strip, useful for those effects which alter the underlying Strip using blur, fade, shift, etc.
• Implemented new Strip implementation SubStrip for addressing a portion of another Strip.
• Implemented AudioTrigger for allowing beat detection over more than one loop, independently for concurrent effects.
  • The triggered method returns true if a beat was detected since the last call (or since the last call to the reset method).
  • Optionally, random triggers can be added (separately for signal detected or not), specifying the number of desired events per second.
• AudioSensor
  • implemented a separate low-pass-filtered RMS sensor for feeding the beat detector, which now responds to low frequencies only.
• Fx
  • implemented strip, audioChannel and state as protected members, so that they don't need to be redefined for each effect implementation.
• Matrix fx
  • Reimplemented without timers, for maximum smoothness.
• PeakMeter fx
  • Reduced flashing on beat detected.
• VU2 fx
  • Implemented new effect.

v1.1.5

Fixed

• AudioChannel
  • Fixed wrong number of FFT bins, now 128 (it was 40).
