Freenove WS2812 Lib for ESP32

Description

This is an Arduino library for controlling ws2812b led on esp32.

Examples:

Here are some simple examples.

Show Rainbow

This example make your strip show a flowing rainbow.

#include "Freenove_WS2812_Lib_for_ESP32.h"

#define LEDS_COUNT  8
#define LEDS_PIN	2
#define CHANNEL		0

Freenove_ESP32_WS2812 strip = Freenove_ESP32_WS2812(LEDS_COUNT, LEDS_PIN, CHANNEL);

void setup() {
  strip.begin();
}

void loop() {
  for (int j = 0; j < 255; j += 2) {
    for (int i = 0; i < LEDS_COUNT; i++) {
      strip.setLedColorData(i, strip.Wheel((i * 256 / LEDS_COUNT + j) & 255));
    }
    strip.show();
    delay(2);
  }  
}

Usage

Freenove_ESP32_WS2812 strip = Freenove_ESP32_WS2812(LEDS_COUNT, LEDS_PIN, CHANNEL, TYPE_GRB);

Construction. Create a strip object.

strip.begin()

Initialization data, ready for communication.

strip.setLedColorData(id, color);
strip.setLedColorData(id, r, g, b);

Send the color data of the specified LED to the controller.
Display color change after calling show function.
- id: the index of led.
- color: color value. egg, 0xFF0000 is RED color.
- r,g,b: color value. 0-255.

strip.show();

Immediately display the color data that has been sent.

strip.setLedColor(id, color);
strip.setLedColor(id, r, g, b);

Send color data and display it immediately.
It is equivalent to "strip.setLedColorData(id, color); strip.show();"
- id: the index of led.
- color: color value. egg, 0xFF0000 is RED color.
- r,g,b: color value. 0-255.
