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);
