Infrared remote controls LED Multicolour is all ffffffff

Using Arduino LEDs and Multiplexing

Hello

I have a question and hope you can help me.

I would like to read out infrared remote controls, that also works quite well with TV remote control, only the LED remote controls multicolor that I want to read, I only get ffffffff, I found this forum entry, but it didn't get me anywhere.

IRremote: Every second value is FFFFFFFF - Using Arduino / Programming Questions - Arduino Forum

I have the code of groundFungus with

irrecv.resume();
Serial.println("...ffffffff");

The result is:

-> ...ffffffff

The questions now are:

  1. Can I not read this LED remote control multicolor at all?

  2. Do I need a different library?

Ich verwende die IDE 2.2.1 mit einem ESP32 und einem VS18388 IR Sensor und dem Code den auch groundFungus verwendet hat plus meine Änderung.

Why did I do this?
I would like to use the LED remote controls multicolor that I have available for the LED control in WLED, at the moment the correct colors are not reproduced.

If anyone has another idea how I can solve the problem with the LED remote controls multicolor in WLED, I would also be very interested!

thanks.

Welcome to the forum

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

Ir-remote controls use different carrier-frequencies
some 36 kHz, some 38 kHz, some 40 kHz.

The datasheet of the VS1838 mentions 38 kHz

If your LED remote uses a different carrier-frequency it does not work.
You might be able to analyse this with a photodiode or a photo-transistor
though I don't have a schematic at hand what other components are required.

Another option is to by IR-receivers with different carrier-frequencies

Hello Stefan,

Thanks for your reply.

Carrier frequencies is probably the key word here.

I thought infrared is always the same and only encoded by the frequency, but it doesn't tell anyone... :sweat_smile:

I have now ordered a TSOP38238, which according to WLED should work with the LED remote controls multicolor.

I'll let you know if I get stuck or if I've solved it.

best regards René
