LedSignaler

Multi-platform library for controlling leds and generating signals on esp32/esp8266 devices. Can be used for various purposes such as indicating status, alerts, or notifications.

Description

LedSignaler uses presets of dots (led On), dashes (led Off) and pause(led off) to generate signals using any onboard led. Presets can also inlcude fading leds in specific patterns.

Features

• Using led presets
• Display running state
• Display error codes on a typical application
• Using threads on esp32 for smoother results

How to use

// include led class
#include "LedSignaler.h"

#ifndef LED_BUILTIN
#define LED_BUILTIN 22
#endif

// Define the led class
LedSignaler led( LED_BUILTIN, LOW);

On ESP8266 call led.update on loop

// Start 2 blinks preset with infinitive loops
led.blink(2, -1);

void loop() {
  led.update();
}

On ESP32 start a blink task

// Start 2 blinks preset with infinitive loops
led.blinkTask(2, -1);

LedSignaler preset call functions

// Wait current preset to end and play a 3 blinks preset.
// At end will return to original preset
led.blinkPush(3, -1);

// Interrupt current preset and play a 3 blinks preset 2 times.
// At end will return to original preset.
led.blinkInject(3, 2);

Compile

Download library files and place them on ./libraries directory under ArduinoProjects Then include the LedSignaler.h in your application and compile..

• compile for arduino-esp3 or arduino-esp8266.

If you get compilation errors on arduino-esp32 you need to update your arduino-esp32 library in the IDE using Boards Manager
