Rpi 3 + Arduino + WS2812B

  • Hi All, really struggling to get this working,


    So I am using Hyperion and Libreelec 8.25, and have successfully installed Hyperion


    The data pin is on pin 6 for the Arduino Sketch, and it flashes red green and then blue twice when booting. After that it stops working. No response from the Hyperion App either.


    Arduino Sketch:


    #include "FastLED.h"


    // How many leds in your strip?
    #define NUM_LEDS 212


    // For led chips like Neopixels, which have a data line, ground, and power, you just
    // need to define DATA_PIN. For led chipsets that are SPI based (four wires - data, clock,
    // ground, and power), like the LPD8806 define both DATA_PIN and CLOCK_PIN
    #define DATA_PIN 6
    #define CLOCK_PIN 13


    #define COLOR_ORDER RGB


    // Adalight sends a "Magic Word" (defined in /etc/boblight.conf) before sending the pixel data
    uint8_t prefix[] = {'A', 'd', 'a'}, hi, lo, chk, i;


    // Baudrate, higher rate allows faster refresh rate and more LEDs (defined in /etc/boblight.conf)
    #define serialRate 460800


    // Define the array of leds
    CRGB leds[NUM_LEDS];


    void setup() {
    // Uncomment/edit one of the following lines for your leds arrangement.
    // FastLED.addLeds<TM1803, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<TM1804, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<TM1809, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<WS2811, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<WS2812, DATA_PIN, RGB>(leds, NUM_LEDS);
    FastLED.addLeds<WS2812B, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<NEOPIXEL, DATA_PIN>(leds, NUM_LEDS);
    // FastLED.addLeds<UCS1903, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<UCS1903B, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<GW6205, DATA_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<GW6205_400, DATA_PIN, RGB>(leds, NUM_LEDS);

    // FastLED.addLeds<WS2801, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<SM16716, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<LPD8806, RGB>(leds, NUM_LEDS);


    // FastLED.addLeds<WS2801, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<SM16716, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);
    // FastLED.addLeds<LPD8806, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);

    // initial RGB flash
    LEDS.showColor(CRGB(255, 0, 0));
    delay(500);
    LEDS.showColor(CRGB(0, 255, 0));
    delay(500);
    LEDS.showColor(CRGB(0, 0, 255));
    delay(500);
    LEDS.showColor(CRGB(0, 0, 0));

    Serial.begin(serialRate);
    Serial.print("Ada\n"); // Send "Magic Word" string to host


    }


    void loop() {
    // wait for first byte of Magic Word
    for(i = 0; i < sizeof prefix; ++i) {
    waitLoop: while (!Serial.available()) ;;
    // Check next byte in Magic Word
    if(prefix == Serial.read()) continue;
    // otherwise, start over
    i = 0;
    goto waitLoop;
    }


    // Hi, Lo, Checksum


    while (!Serial.available()) ;;
    hi=Serial.read();
    while (!Serial.available()) ;;
    lo=Serial.read();
    while (!Serial.available()) ;;
    chk=Serial.read();


    // if checksum does not match go back to wait
    if (chk != (hi ^ lo ^ 0x55))
    {
    i=0;
    goto waitLoop;
    }


    memset(leds, 0, NUM_LEDS * sizeof(struct CRGB));
    // read the transmission data and set LED values
    for (uint8_t i = 0; i < NUM_LEDS; i++) {
    byte r, g, b;
    while(!Serial.available());
    r = Serial.read();
    while(!Serial.available());
    g = Serial.read();
    while(!Serial.available());
    b = Serial.read();
    leds.r = r;
    leds.g = g;
    leds.b = b;
    }
    // shows new values
    FastLED.show();
    }
