LightShow is a C++11 library for displaying light patterns on NeoPixel strips.
See https://ckxng.github.io/arduino-LightShow/html/hierarchy.html
This library has been designed and tested using:
- fastled/FastLED@^3.5.0
- adafruit/Adafruit NeoPixel@^1.10.4
Both the NeoPixel and FastLED libraries are implemented as classes sharing a common LightShow::Controller interface. If
one of these libraries is not available at compile-time in your development environment, you can disable all references
to the offending library by editing LightShow.h and setting the related #define LIGHTSHOW_*_ENABLE entries to 0.
Please note that the FastLED implementation is somewhat awkward, as FastLED is a static implementation, while the NeoPixel library is not. Creating more than one instance of the LightShow::FastLEDController is undefined behavior.
FastLED version:
#define CONFIG_NEOPIXEL_COUNT 30
#include <Arduino.h>
#include "FastLEDController.h"
#include "PulseColorPreset.h"
#include <memory>
#define LIGHTSHOW_FASTLED_DATA_PIN PIN_A1
auto controller =
std::make_shared<LightShow::FastLEDController>(CONFIG_NEOPIXEL_COUNT);
auto preset = LightShow::PulseColorPreset(controller, 0xFF, 0, 0, 10000, 100);
void setup() {
preset.Start();
}
void loop() {
preset.Loop();
}
Neopixel version:
#define CONFIG_NEOPIXEL_COUNT 30
#include <Arduino.h>
#include "NeoPixelController.h"
#include "PulseColorPreset.h"
#include <memory>
auto controller = std::make_shared<LightShow::NeoPixelController>(
CONFIG_NEOPIXEL_COUNT, PIN_A1);
auto preset = LightShow::PulseColorPreset(controller, 0xFF, 0, 0, 10000, 100);
void setup() {
preset.Start();
}
void loop() {
preset.Loop();
}
By instantiating multiple presets, you can assign those presets to pointer, which can then be switched between and Loop()ed on. This is a more advanced usage of the library, and requires at least a basic understanding of pointers in C++.
auto preset_flash =
std::make_shared<LightShow::FlashColorPreset>(controller, 0xFF, 0, 0, 10000);
auto preset_solid =
std::make_shared<LightShow::SolidColorPreset>(controller, 0xFF, 0, 0);
auto preset_pulse =
std::make_shared<LightShow::PulseColorPreset>(controller, 0xFF, 0, 0, 10000, 100);
auto preset_blank = std::make_shared<LightShow::Preset>();
std::shared_ptr<LightShow::Preset> current_preset = preset_blank;
void SomeCodeThatChangesPresets() {
current_preset = preset_pulse;
}
