GARLAND MODULE
Copyright (C) 2020 by Dmitry Blinov <dblinov76 at gmail dot com>
Inspired by https://github.com/Vasil-Pahomov/ArWs2812 (currently https://github.com/Vasil-Pahomov/Liana)
Tested on 300 led strip.
The most time consuming operation is actually showing leds by Adafruit Neopixel. It take about 1870 mcs.
More long strip can take more time to show.
Currently animation calculation, brightness calculation/transition and showing makes in one loop cycle.
Debug output shows timings. Overal timing should be not more that 3000 ms.
MQTT control:
Topic: DEVICE_NAME/garland/set
Message: {"command":"string", "enable":"string", "brightness":int, "speed":int, "animation":"string",
"palette":"string"/int, "duration":int}
All parameters are optional.
"command:["immediate", "queue", "sequence", "reset"] - if not set, than "immediate" by default
Commands priority:
- "immediate" - executes immediately, braking current animation.
- "queue" - if queue is not empty, than next queue command executes after current animation end.
after execution command removed from queue.
- "sequence" - executes commands in sequence in cycle.
- "reset" - clean queue and sequence, restore default settings, enable garland.
- random if there are no commands in queue or sequence.
"enable":["true", "false"] - enable or disable garland
"brightness":[0-255] - set brightness
"speed":[30-60] - set animation speed
"animation":["PixieDust", "Sparkr", "Run", "Stars", "Spread", "R"andCyc", "Fly", "Comets", "Assemble", "Dolphins", "Salut"]
- setup animation. If not set or not recognized, than setup previous anmation
"palette":["RGB", "Rainbow", "Stripe", "Party", "Heat", Fire", "Blue", "Sun", "Lime", "Pastel"]
- can be one of listed above or can be one color palette.
- one color palette can be set by string, that represents color in the format "0xRRGGBB" (0xFF0000 for red) or
integer number, corresponding to it. Examples: "palette":"0x0000FF", "palette":255 equal to Blue color.
"duration":5000 - setup command duration in milliseconds. If not set, than infinite duration will setup.
If command contains animation, palette or duration, than it setup next animation, that will be shown for duration (infinite if
duration does not set), otherwise it just set scene parameters.
Infinite commands can be interrupted by immediate command or by reset command.
