Neopixel FX library for Mongoose OS based on kitesurfer1404/WS2812FX and compatible with Adafruit NeoPixel library.

Example Javascript code:

load('api_ws2812fx.js');

// 8 pixels on GPIO5
let p = WS2812FX.create(8, 5, WS2812FX.NEO_GRB + WS2812FX.NEO_KHZ800);
p.setBrightness(WS2812FX.BRIGHTNESS_MAX);
p.setSpeed(1000);
p.setColor(0x007BFF);
p.setMode("RAINBOW_CYCLE");
p.start();

Example C++ code:

#include "mgos.h"
#include "mgos_arduino_WS2812FX.h"

enum mgos_app_init_result mgos_app_init(void) {
  WS2812FX *p = mgos_WS2812FX_create(8, 5, NEO_GRB + NEO_KHZ800);
  mgos_WS2812FX_init(p);
  mgos_WS2812FX_setBrightness(p, 255);
  mgos_WS2812FX_setSpeed(p, 1000);
  mgos_WS2812FX_setColor(p, 0x007BFF);
  mgos_WS2812FX_setMode(p, FX_MODE_RAINBOW_CYCLE);
  mgos_WS2812FX_start(p);
  return MGOS_APP_INIT_SUCCESS;
}
