Zitat von Bub4

Der Plattform Grabber wird NOCH nicht unterstützt. Du solltest dann vorerst bei LE9.2 bleiben.

Der interne grabber funktioniert noch nicht mit LE10/Matrix

Hast du auch den Port mit angegeben?

Also IP-Adresse : Port-Nummer

z.B.

192.168.1.10:8090

Changes you make on the "Remote Control" settings page are temporarily and lost after restart.

Activate "Enable screen capturing" under "LED instances" -> "Sources" and

check "Activate" under "Capturing Hardware"

Hi,

überprüfe bitte, ob du mit dem Handy auch wirklich die gleiche Adresse wie mit deinem Rechner aufrufst und sich beide Geräte im gleichen Netzwerk befinden.

Sorry, but i (maybe) found an other issue:

The 2nd step in the color calibration wizzard allows you to define a name for the color profile

unfortunately setting a name here causes the leds not to react to the adjustments you do in the next steps.

You first have to create a custom profile on the image processing settings page!

Afterwards, the calibration wizzard gives you the option to select one of your created profiles

and then the rest of the calibration works like expected.

Hi Lord-Grey,

Zitat von Lord-Grey

a) send a reference color to Kodi (e.g. Red)

b) Kodi displays a red screen

c) Hyperion's internal grabber captures the screen

d) LEDs display what was captured

Understood! Now it makes absolutly sense why the LEDs are off if screen capturing is disabled.

Thanks for your explanation.

Topic can be closed.

Best regards

Hi everybody,

after struggling around with my setup quite a time, i finally noticed that the LEDs won´t light up in calibration mode

if screen capturing is disabled in the remote control settings.

Is this wanted that way or a bug?

Best regards

Zitat von Lord-Grey

Hyperion cannot not see what you bought and have connected....
There seems to be different strips out there with different datasheet specs, but same protocol. Therefore, you can overwrite it.

A type-x led is a type-x therefore i select it in settings or not?

But of course you are right, specs and setups vary, i also forgot that i enabled expert mode

Thank you for spending your time to give me support and the Hyperion Project in general!

Schönen Sonntag noch!

OK, now i got it.

"Rewrite Time" is really more intuitive, thats true.

But you lead me to a next question:

Due the latch time is specific for the type and amount of Leds,

then why can i change it? Doesn't Hyperion calculate the minimum latch time itself?

Increasing the latch time would maybe make sense to lower transmission errors.

Hi Lord-Grey,

erstmal Danke für deine Erklärung.

Leider verstehe ich das immer noch nicht ganz.

Zitat

time-frame a device requires until the next update can be processed

time frame a devices requires to be refreshed

Ist für mich irgendwie das gleiche

Konkretes Beispiel WS2812b, aus dem Datenblatt:

Nutze ich 2 Leds sind das:

minimum (TH+TL-0,6µs) pro Bit x 24bit pro Led x 2 Leds + 50µs Reset = 81,2µs

Das wäre dann also die Latch Zeit, oder?

Hi all,

it would be nice if anybody can tell me the difference between reset time and latch time in hyperion settings?

I dont really find a explanation.

Thanks for clarification.

Best regards

Hi Hyperion-Team,

i noticed that the "invert signal" option does work when using ws2812 in spi mode,
but when using ws2812 in pwm mode, nothing happens. The signal remains the same.

Hi Hyperion-Team,

it would be great to see Hyperion supporting the internal grabber of the new LibreElec 10 release on the Raspberry Pi.

Best regards

Marxon

Although it would be interesting to know where the signal come from, I switched from SPI to PWM

and so far everything seems to work.

Maybe I should ask in a other forum for help to investigate my SPI problem further.

Thanks a lot.

Marxon

Thanks for your response.

Zitat von Lighting-guy77

maybe bad PSU or bad grounding.

No I don´t think so.

Because like i said, the signal disappears when selecting a none SPI-type led in settings.

Zitat von Lightning-guy77

3 line ledstrips are sometimes difficult to run on SPI because of the lack of CLK signal. Then you have to play with baudrate settings and such.

Yes this is true, but the problem is that unknown signal

Zitat von TPmodding

does the signal has 2,72V?

No it doesn´t.

2,72V was my trigger voltage.

The signal has 3,24V.

Does anybody know how to check in Linux if any other programm in the background is running which uses the SPI port?

It seems no one else having a similar problem in the forum, but maybe someone can help nevertheless.

Everything works so far but there is some kind of repeating external signal superimpose (i hope this is the correct english word)

the communication which causes flickerig and i dont know its source.

It also occurs when no effect is running but it disappears when selecting a none SPI-type led in settings.

I checked the signal with my oscilloscope @ 1ms, 50us, 10us, 1us

Where could this signal come from?

Best regards

Hi everybody,

i use LibreElec on a RPi4 with WS2812B and a 3,3V-5V level shifter.

Unfortunately the level shifter is not fast enough.

Is it possible to increase the duration of a high impulse?

Thanks for any help
