ESP8266 ESP-12 Neopixel Strip
Posted: Wed Sep 02, 2015 11:49 amI fleeced a bit of this code from other people and the images from various sites. It's pretty loose at the moment, needs some tweaking on some of the functions. I had to re-write some of the Adafruit Neopixel examples to use millis() instead of delay() Feel free to borrow, modify as you see fit. I've commented a good bit at the start and then got side tracked but it should be simple enough to understand. It should also be simple enough to set it up as a wifi host rather than a client.
Code: Select all
#include <Adafruit_NeoPixel.h>
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
//#define DEBUG //enable debug mode (serial out enabled on specific functions)
#define PIN 13 //sets the pin on which the neopixels are connected
#define NUMPIXELS 30 //defines the number of pixels in the strip
#define interval 50 //defines the delay interval between running the functions

uint32_t pixelColour;
float activeColor[] = {255, 0, 0};//sets the default color to red
boolean LEDstate[] = {false, false, false, false, true, false, false, false, false, false, false, false, false, false}; //saves the state of each of the functions
const char* ssid = "InsertWifiSSID";
