# LEDManager Library
## Overview
The LEDManager library provides a flexible and easy-to-use interface for controlling LEDs in projects. It supports both addressable LED strips and individual non-addressable LEDs, offering various modes of operation such as static, blinking, and pulsing. The library is designed to work seamlessly with PlatformIO and can be easily configured using build flags.
## Features
- Support for both addressable LED strips and individual non-addressable LEDs
- Multiple operation modes: OFF, STATIC, BLINK, and PULSE
- Individual control of LEDs within each strip (for addressable LEDs)
- Global brightness control
- Queueing of LED states for complex sequences
- Automatic return to previous state after temporary modes
- Compatible with PlatformIO build flags for easy configuration
- Customizable color schemes
## Installation
1. Clone this repository or download the ZIP file.
2. Extract the contents to your PlatformIO project's `lib` directory.
## Configuration
Configure the LEDManager library using build flags in your `platformio.ini` file:
```ini
build_flags =
; For addressable LEDs:
-DLED_ADDRESSABLE=true
; For non-addressable LEDs, comment out the line above
; If the Addressable LED requires power
-DLED_ADDRESSABLE_POWER=15
; Optional timing configurations:
-DBLINK_INTERVAL=500
-DPULSE_INTERVAL=30
-DFADE_AMOUNT=5
```
## Usage
Here's a basic example of how to use the LEDManager library:
```cpp
#include "LEDManager.h"
LEDManager ledManager;
void setup() {
#ifdef LED_ADDRESSABLE
ledManager.addLEDStrip(5, 30); // Add addressable LED strip on pin 5 with 30 LEDs
#else
ledManager.addLEDStrip(5, 1); // Add non-addressable LED on pin 5
ledManager.addLEDStrip(6, 1); // Add non-addressable LED on pin 6
#endif
ledManager.setBrightness(128); // Set global brightness to 50%
}
void loop() {
#ifdef LED_ADDRESSABLE
// Set all LEDs on the first strip to static green
ledManager.setMode(0, -1, LEDManager::STATIC, LED_COLOR_GREEN);
// Blink first 5 LEDs red for 3 times on the first strip
for (int i = 0; i < 5; i++) {
ledManager.setMode(0, i, LEDManager::BLINK, LED_COLOR_RED, 3);
}
#else
// Set first LED to static green
ledManager.setMode(0, 0, LEDManager::STATIC, LED_COLOR_GREEN);
// Blink second strip LED red
ledManager.setMode(1, 0, LEDManager::BLINK, LED_COLOR_RED, 3);
#endif
ledManager.update();
delay(100);
}
```
## API Reference
### Initialization and Setup
```cpp
LEDManager ledManager;
ledManager.addLEDStrip(int pin, int numLeds);
```
### Setting LED Mode
```cpp
ledManager.setMode(int stripIndex, int ledIndex, Mode mode, uint32_t color, int durationOrBlinkCount = -1);
```
- `stripIndex`: Index of the LED strip (0-based)
- `ledIndex`: LED index within the strip (0-based) or -1 for all LEDs in the strip (addressable LEDs only)
- `mode`: `LEDManager::OFF`, `LEDManager::STATIC`, `LEDManager::BLINK`, or `LEDManager::PULSE`
- `color`: Color value (use predefined colors from LEDColorDefinitions.h or custom 24-bit RGB values)
- `durationOrBlinkCount`: Duration for STATIC mode (in milliseconds), blink/pulse count for BLINK/PULSE modes (-1 for infinite)
### Setting Brightness
```cpp
ledManager.setBrightness(brightness);
```
- `brightness`: Global brightness value (0-255)
### Updating LEDs
Call this method in your main loop to update LED states:
```cpp
ledManager.update();
```
## Advanced Configuration
You can customize the behavior of the LEDManager by defining the following build flags:
- `BLINK_INTERVAL`: Sets the interval (in milliseconds) between blink states (default: 500)
- `PULSE_INTERVAL`: Sets the interval (in milliseconds) between pulse updates (default: 30)
- `FADE_AMOUNT`: Sets the increment/decrement value for pulsing (default: 5)
