Artnet, WS2812 and ESP8266 (Arduino IDE)

From my previous post I have updated the program to be compiled from Arduino IDE.

#include <ESP8266WiFi.h>
#include <WiFiUdp.h>
#include <Adafruit_NeoPixel.h>

#define WSout 5                                     // Pin D1
#define ARTNET_PORT 6454

#define PIXELCOUNT 100


byte hData[318];

const int number_of_channels=300; //512 for 512 channels

const char* ssid     = "";
const char* password = "";

Adafruit_NeoPixel pixels = Adafruit_NeoPixel(PIXELCOUNT,WSout,NEO_GRB+NEO_KHZ800);

WiFiUDP udp;


IPAddress local_ip(192, 168, 1, 190);
IPAddress gateway_ip(192, 168, 1, 1);
IPAddress subnet_ip(255, 255, 255, 0);

void setup() {
  
  Serial.begin(115200);
  delay(100);
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);

  WiFi.begin(ssid, password);
  WiFi.config(local_ip, gateway_ip, subnet_ip);

  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  udp.begin(ARTNET_PORT); // Open ArtNet port

  Serial.println("");
  Serial.println("WiFi connected");
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());


pixels.begin();

  for(byte i=0;i<PIXELCOUNT;i++){
    pixels.setPixelColor(i, Color(0,0,0));
  }
  pixels.show();
  
}

void loop() {
  if (udp.parsePacket()) {
    udp.read(hData, 318);
   // pixels.setPixelColor(0, Color(hData[19], hData[20],hData[21]));
  for ( int n=0; n<100; n++){   
     pixels.setPixelColor(n, Color(hData[(n * 3) + 19], hData[(n *3)+20],hData[(n *3)+21]));
    }
   pixels.show();
  }
}

uint32_t Color(byte r, byte g, byte b){
  uint32_t c;
  c = r;
  c <<=8;
  c |= g;
  c <<= 8;
  c |= b;
  return c;
}

The WS2812 data line is connected to D1 from the NODEMCU board.

Config of the Arduino IDE

It looks like it work better than the code in Lua.

This comes from a similar program I did few years ago to run 10 matrices of 10 x 10 pixels. I was using WS2801 led stripes, arduino UNO and ethernet shield.

Everything still runs smooth untill now.

Some photos of matrix installed and the controller running JINX.
