ESP32 problem with channel 0 already used for display

[DWilhelmLKKS]

Hello community,

I'm using the following libraries for driving my WT32-SC01 Plus (ESP32-S3) and it works really well:

• ArduinoJson by Benoit Blanchon v7.0.4
• LovyanGFX by lovyan03 v1.1.12
• lvgl by kisvegabor v9.1.0
• SD by Arduino, SparkFun v1.2.4

However, when I add IRremote (v4.3.1) for just sending signals the display always gets dark (after sending with IrSender.sendNECRaw("0x6F905583")).
Using IRremoteESP8266 v2.8.6 everything works fine but the library seems to need other codes and has less functionality.

This is my IR specific code:

// configuration
#define DISABLE_CODE_FOR_RECEIVER
#define ESP32
#define IR_SEND_PIN 10

// includes
#include <IRremote.h>

// initialize
void setup() {
  IrSender.begin(ENABLE_LED_FEEDBACK, USE_DEFAULT_FEEDBACK_LED_PIN);
}

// main
void loop() {
  lv_task_handler(); 
  lv_tick_inc(5);
  delay(5);
}

I think it could be a problem with a timer but the docs say that no timer is needed for sending signals...
Does somebody have a solution for this?

Ever tried
disableLEDFeedback(); // Disable feedback LED at default feedback LED pin

I tried it now, changing my code to

// initialize
void setup() {
  IrSender.begin();
  disableLEDFeedback();
}

but it had no effect.

Then is pin 10 the wrong one!

What do you mean with wrong pin?
Using another IR library with pin 10 (in combination with the display) works fine.
Even with IRremote the codes itself are working and I can control the remote device via my ESP.

Then try to change line 1439 in IRTimer.hpp

Thank you! You saved my life! 😄
That did the trick.
