我只能通过来自 Vixen 灯的串行数据控制 LED 灯带的前 6 个像素，Arduino RF ws2811 像素控制器

Question

我正在尝试编写两个脚本，一个 Tx 和一个 Rx，它们是使用从 vixen lights 软件发送的串行数据来控制的。 接收脚本

#include <RF24.h>

#define DATA_PIN 6
#define NUM_LEDS 100
#define MAX_CHANNELS NUM_LEDS * 3
CRGB leds[NUM_LEDS];

RF24 radio(9, 10);

byte addresses[][6] = {"Vixen1"};

void setup() {
  Serial.begin(115200);
  FastLED.addLeds<WS2812B, DATA_PIN, RGB>(leds, NUM_LEDS);
  
  radio.begin();
  radio.setPALevel(RF24_PA_MAX);
  radio.setDataRate(RF24_2MBPS);
  radio.setChannel(124);
  radio.openReadingPipe(0, addresses[0]);
  radio.startListening();
}

void loop() {
  if (radio.available()) {
    byte incomingByte[MAX_CHANNELS];
    radio.read(&incomingByte, sizeof(byte) * MAX_CHANNELS);

    // Calculate the number of pixels based on the incomingByte array
    unsigned int num_leds = sizeof(incomingByte) / 3;
    // Ensure the number of pixels does not exceed the number allowed
    if (num_leds > NUM_LEDS) {
      return;
    }

    // Loop through each of the pixels and read the values for each color
    for (int i = 0; i < num_leds; i++) {
  int channel = i * 3;
  leds[i].r = incomingByte[channel];
  leds[i].g = incomingByte[channel + 1];
  leds[i].b = incomingByte[channel + 2];
}

    // Tell the FastLED Library it is time to update the strip of pixels
    FastLED.show();
  }
}

TX脚本

#include "Arduino.h"
#include <SPI.h>
#include <RF24.h>

// How many channels Vixen will control
#define MAX_CHANNELS 300

// Stores the value of each channel
byte outgoingByte[MAX_CHANNELS];

// Uses SPI bus + two digital pins for chip enable (CE) and chip select (CSN)
RF24 radio(9, 10);

// An address used by the transmitter and receiver
// Changing this address would allow multiple Vixen server instances to control
// different sets of clients while still operating on the nRF channel.
byte addresses[][6] = {"Vixen1"};

void setup() {
  Serial.begin(115200);

  radio.begin();
  radio.setPALevel(RF24_PA_MAX);
  radio.setDataRate(RF24_2MBPS);
  radio.setChannel(124);
  radio.openWritingPipe(addresses[0]);
}

void loop() {

  // Keeps track of place in byte array and how many channels are left to be read
  unsigned int remaining;
  unsigned int channel;

  for (;;) {

    // Header character is used to keep the Arduino in sync with first channel as Vixen sequentially
    // writes out each byte for every channel.
    while (!Serial.available());
    if (Serial.read() != '>') {
      continue;
    }

    remaining = MAX_CHANNELS;
    channel = 0;

    do {
      while (!Serial.available());
      outgoingByte[channel++] = Serial.read();
    }
    while (--remaining);

    // Write out the byte array of channel values to the nRF
    radio.write(&outgoingByte, sizeof(byte) * MAX_CHANNELS);

  }
}

使用这些脚本

我试过搜索互联网但到目前为止没有解决方案。我只能从通用串行控制我的灯条上的前 6 个像素，我在我的 Vixen 灯软件中使用了一个标头，它是 <100> 100 表示 LED 的数量，每个 LED 有 3 个通道用于 RGB 值。我难住了。任何提示，建议非常感谢。 谢谢。
