I ask for help.
There is a bunch of Jinx! (PC) to ESP32 (Devkit V1).
An access point has been created on the ESP, the PC is connected to it.
First, the connection (Code 1) to the matrix with 462 LEDs. Everything almost works fine, sometimes it slows down.
When I increase the number of LEDs by 4 times, I create 4 parallel outputs in the code. (Code 2).
Change settings in Jinx! on the required number of LEDs.
There is a very unstable work, frequent freezing.
I ask for your help. What could be the problem?

Code 1

Code: Select all

#include <ArtnetWifi.h>
#include <Arduino.h>
#include <FastLED.h>

// Wifi Настройки
const char* ssid = "AAA";
const char* password = "12345678";
WiFiServer server(80);

// LED Настройи

const int numLeds = 462; // 22*21
const int numberOfChannels = numLeds * 3; // Total number of channels you want to receive (1 led = 3 channels)
const byte dataPin = 2;
CRGB leds[numLeds];

// Art-Net settings
ArtnetWifi artnet;
const int startUniverse = 0; // CHANGE FOR YOUR SETUP most software this is 1, some software send out artnet first universe as 0.

// Check if we got all universes
const int maxUniverses = numberOfChannels / 512 + ((numberOfChannels % 512) ? 1 : 0);
bool universesReceived[maxUniverses];
bool sendFrame = 1;
int previousDataLength = 0;
// connect to wifi – returns true if successful or false if not


void onDmxFrame(uint16_t universe, uint16_t length, uint8_t sequence, uint8_t* data)
{
  sendFrame = 1;
  // set brightness of the whole strip
  if (universe == 15)
  {
    FastLED.setBrightness(data[0]);
    FastLED.show();
  }

  // Store which universe has got in
  if ((universe - startUniverse) < maxUniverses) {
    universesReceived[universe - startUniverse] = 1;
  }

  for (int i = 0 ; i < maxUniverses ; i++)
  {
    if (universesReceived[i] == 0)
    {
      //Serial.println("Broke");
      sendFrame = 0;
      break;
    }
  }

  // read universe and put into the right part of the display buffer
  for (int i = 0; i < length / 3; i++)
  {
    int led = i + (universe - startUniverse) * (previousDataLength / 3);
    if (led < numLeds)
      leds[led] = CRGB(data[i * 3], data[i * 3 + 1], data[i * 3 + 2]);
  }
  previousDataLength = length;

  if (sendFrame)
  {
    FastLED.show();
    // Reset universeReceived to 0
    memset(universesReceived, 0, maxUniverses);

   server.begin();

  Serial.println("Server started");
  artnet.begin();
  
  FastLED.addLeds<WS2812, dataPin, GRB>(leds, numLeds);


  // this will be called for each packet received
