Management of LED strips

lightbar

What is lightbar?

Simple packet communication between 900mhz radios. reciever is half of the solution, the other half is in the transmitter application.

Purpose

Starting point for custom LED strip installs

Software Dependencies

• FastLED https://github.com/FastLED/FastLED
• buttonhandler https://github.com/ericklein/buttonhandler
• encoder https://github.com/PaulStoffregen/Encoder
• Adafruit NeoPixel https://github.com/adafruit/Adafruit_NeoPixel

BOM

• 1 or more: Adafruit Rotary Encoder 377b
• 1 or more: simple buttons
• LED strip; any supported by FastLED or Adafruit NeoPixel (for RGBW)
• optional: Blinkytape (Arduino Leonardo with 60 WS2811)
• 1X: MCU if not Blinkytape
• 1 protoboard
• wire

Pinouts

• buttons to digital pin, ground
• rotary encoder to interupt enabled pins, ground
• LED strip to data pin(s), independent 5v, power GND + Arduino GND

Information Sources

• See Evernote note on wiring for LED strips.

Issues

• 111820 - [P1] Code does not compile when lightfieldeffects.ino is included. Code needs to be transitioned to David's LEDControl library

Revisions

• 10/17/14
  • fork from example to control LPD8806-based RGB LED Modules in a strip
  • added multiple button support, will be augmented/replaced by rotary encoder in future version
• 11/15/14
  • prototypes for desired lighting functions (lightXxYy)
• 04/21/15
  • fixed bugs in lightColorFill
• 03/02/16
  • first version in GitHub
  • added rotary encoder, code is extremely crude
• 04/27/16
  • 03/02/16 - rotary encoder push is captured
  • code readability improved, still much to do
• 05/22/16
  • changed rotation tracking to boolean
  • 03/02/16 - fixed wrap-around of intensity bug
  • moved light test script from loop() to lightTest, no dev work done on function itself
  • hard coded button functionality, now can comment out functionality based on hardware config
• 12/27/16
  • completed 05/22/16 revisions
  • 03/02/16 - switch from LED intensity (one value) to r,g,b levels
• 12/29/16
  • fixed bug in blue to white transition
  • 04/21/15 - move light functions to library
  • 03/02/16 - added off (0) state to stripColor to control On/Off
  • 03/02/16 - added "powered" On/Off state with control from rotary encoder; Arduino and LED are powered, LEDs at 0,0,0
• 07/19/17
  • Moved revision history, feature requests, build targets, etc. to README.md
  • refactored code in loop() 07/29/17
  • 03/02/16 - can I use FastLED or other generic library
• 08/01/17
  • 04/27/16 - consistent use of wire color for ground, etc.
  • 12/27/16 - standard connectors for LED strip
  • 07/29/17 - FastLED 3.1 upgrade
  • 07/29/17 - move LED pins to SPI
  • 07/29/17 - how do I checkin code with new filename
• 08/06/17
  • 07/29/17 - fix lightfieldeffects.ino after FastLED transition
• 11/21/17
  • completed lightfieldeffects.ino fixes after FastLED transition
  • conditional code branching for blinkytape and LPD8806 11/26/17
  • 12/29/16 - button support to library
  • 11/20/17 - button globals probably don't need to be global
• 05/05/19
  • [FR 08/06//17] should I run a FastLED.clear() before each light function?
    • Yes, functions don't clear themselves so higher logic can control this
  • [FR 08/06/17] switch delay() to FastLED.delay function?
    • No, FastLED.delay() only for platforms without native delay() function
  • added brightness parameter to lightColorChase, lightTheatreChase
  • updated button initialization based on changes to button library
• 06/02/19
  • variable name changes to improve code readability
  • function name alignment missed during 05/05/19 changes
  • [FR 05/10/19] ARM compilation
  • [FR 03/02/16] CRGB::Red is green and CRGB::Green is Red [LPD8086]
• 04/25/20
  • [FR 11/24/17] transition to encoder library for rotary encoder support
  • [FR 05/22/16] why do I care about halfLeft and halfRight? -> CLOSED with encoder.h
  • [FR 11/20/17] enum stripColor for readability
  • [FR 11/24/17] stripColor should not also embed on/off status (see 03/02/16), impacts resolveButtons
  • [FR 11/24/17] implement DEBUG flag for print and println and put !Serial under that debug flag
  • RGBW strip support via Adafruit NeoPixel library
• 111820
  • Added more control for RGBW strips
