Description

Since 2.0.2, the compiler claims that the call tone(TONE_PIN, 1100) is ambiguous, which is totally nonsense 😞 . see sketch below.

Sketch

#include <Arduino.h>
void setup() {
  // put your setup code here, to run once:

}

#define TONE_PIN                27  // D27 25 & 26 are DAC0 and 1
#define TONE_LEDC_CHANNEL        1  // Using channel 1 makes tone() independent of receiving timer -> No need to stop receiving timer.
void tone(uint8_t aPinNumber, unsigned int aFrequency){
    ledcAttachPin(aPinNumber, TONE_LEDC_CHANNEL);
    ledcWriteTone(TONE_LEDC_CHANNEL, aFrequency);
}
void tone(uint8_t aPinNumber, unsigned int aFrequency, unsigned long aDuration){
    ledcAttachPin(aPinNumber, TONE_LEDC_CHANNEL);
    ledcWriteTone(TONE_LEDC_CHANNEL, aFrequency);
    delay(aDuration);
    ledcWriteTone(TONE_LEDC_CHANNEL, 0);
}
void noTone(uint8_t aPinNumber){
    ledcWriteTone(TONE_LEDC_CHANNEL, 0);
}
void loop() {
  // put your main code here, to run repeatedly:
            tone(TONE_PIN, 1100); // what is the compiler doing here???
            delay(50);
            tone(TONE_PIN, 1100, 10);
            delay(50);
}

Other Steps to Reproduce

Just compile!

I have checked existing issues, online documentation and the Troubleshooting Guide

Hi @ArminJo,
It may be due to tone function is already implemented in 2.0.3. Check this PR #6402.
@PilnyTomas can help if needed.

Thanks!!!
Any idea how I can check core version in c preprocessor?

Thanks!!! 🥇
it works now https://github.com/Arduino-IRremote/Arduino-IRremote/blob/81e49468b5f33ead1361015fb1927b4ee4cc701a/examples/SimpleReceiver/PinDefinitionsAndMore.h#L69
