cannot address more than 255 leds

Hi folks,
I am new to the forum and using Hyperion and ran into a problem.
The following is my problem, I made a 100"projector screen with 408 LEDs W2812b ..Arduino connected to RPI3 with HYPERION software. All 408 LEDs function if I upload a sketch to the Arduino no matter what I use color effects, etc. its all working properly.
Only i cannot use hyperion whit more than 255 leds on .
Even ambilight works but only 255 leds .
I have to chance the sketch for arduino to 255 addressable leds en then it will work .
i dont think its a problem with the ledstrips because its working with the arduino software just not in combination Hyperion ..

So any help would be welcome ..
Grtz Frank

Arduino R3 Uno
RPI 3 OSMC
W2812B ledsstrip 60 leds p/m +- 6 meters

@penfold42 thanks for your reply ..

So i have bin testing with your sketch and mine (ambilight**2)
With your sketch i can set 408 leds and when the arduino is finished uploading all lights are up , hyperion starts , ambilight works but only 207 Leds light up.
When i use my sketch and set 408 leds after finishing upload to arduino all lights are up ,hyperion starts , no working ambilight ..
Its getting better ...

With your sketch i can set 255 leds and when the arduino is finished uploading all 255 lights are up , hyperion starts , ambilight works but only 207 Leds light up.
When i use my sketch and set 255 leds after finishing upload to arduino all 255 lights are up ,hyperion starts , ambilight works but only 255 Leds light up thats because i set to 255.. when i go any higher hyperion stops working ...

So.....

I also replaced a meter leds after led 205 ..but problem stays exactly the same ..

Hi penfold42,
Thanks for the help ..
I've changed the sketch (uint8_t to int)

#include "FastLED.h"

// How many leds in your strip?
#define NUM_LEDS 408

// 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 COLOR_ORDER GRB

// 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 500000

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

void setup() {
FastLED.addLeds<WS2812B, DATA_PIN, COLOR_ORDER>(leds, NUM_LEDS);

// initial RGB flash, comment out if your setup works.
//LEDS.showColor(CRGB(255, 255, 255));
//delay(500);
//LEDS.showColor(CRGB(100, 0, 0));
//delay(1000);
//LEDS.showColor(CRGB(255, 255,255));
//delay(500);
//LEDS.showColor(CRGB(0, 0, 100));
//delay(1000);
LEDS.showColor(CRGB(100, 0, 0));
delay(1000);
//LEDS.showColor(CRGB(255, 255,255));
//delay(500);
LEDS.showColor(CRGB(0, 0, 100));
delay(1000);
LEDS.showColor(CRGB(175,125,55));

// start listening on serial port
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 (int 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();
}

Now all leds are working with this sketch and react to hyperion grabber....BUT..
The leds behavior is off ..
The leds right and top have the same color as the screen but left and bottom are just copy's of right and top !
diagonal screen mirror color..
tested with the hyperion color calibration pictures .
Why? ******has it something to do with the code ..

sketch you provided only lights up 207 lights after the changes .

yes it does ..
(knightrider effect)
when red light on top goes from right to left ,bottom goes from left to right..exact same timing ..
left and right side blink red at the same time ..

With snake effect i got 2 red lights ..probably only has to be one ..?

sadly enough,i did not otherwise the solution was easy ...
still having the mirror effect ...:facepalm:

So nobody encountered the same issue as me ....??

ledstrip defect?
