Tried to make a beeping sound

[Blaubart]

Hi,

I tried to make a beeping sound so I used gen.SleepMode(true); and gen.SleepMode(false); to start and stop the sound. But I get a clicking noise. Is there a better way to realise beeping?

I am having a similar issue, were you able to solve it? https://forum.arduino.cc/t/popping-sound-when-disabling-output-from-sine-tone-generator-ad9833/1099574

[Blaubart]

I solved it by using while loop and two commands: gen.IncrementFrequency (REG0, freq); gen.ApplySignal(SINE_WAVE, REG0, 0);

gen.IncrementFrequency is able to increase or decrease frequency gradually to the value you like to have. If the sound should stop I use gen.ApplySignal(SINE_WAVE, REG0, 0);

I tried gen.ApplySignal(SINE_WAVE, REG0, 0); but the clicking is the same as with gen.EnableOutput(false); Do you keep decreasing frequency till 0?

[Blaubart]

Yes I decreased till 0

I start at freq 5000 and then did this

    for (int i = 0; i < 5; i++) {
        gen.IncrementFrequency(REG0, -1000);
    }
    gen.ApplySignal(SINE_WAVE, REG0, 0);

But the click is still there. Can you post your code?

[Blaubart]

    freqValueNeg = (-1 * freqValueOld) / 8;
    int  i = 0;
    while (i < 8 && freqValueNeg < 0) {
      i = i + 1;
      gen.IncrementFrequency (REG0, freqValueNeg);
      delay(1);
    }
    gen.ApplySignal(SINE_WAVE, REG0, 0);
    freqValueOld = 0;

I still find the cleanest turn off is using

      gen.EnableOutput(true);
      delay(1000);
      gen.EnableOutput(false);

Thanks bro for your help

pefect! Sorry, that I couldn’t really help!!
