Deej preventing computer from sleeping, could not get any solutions from google to work

[BolSadguy]

So sorry to be making another post about this issue but I've tried disabling usb wake up in my device manager (the button to disable it just doesnt exist on my end for some reason) and I've also tried adjusting the arduino code based on #52 and I haven't been able to get my computer to remain in sleep while deej is running. Admittedly I don't know too much about programming arduinos so I'm not sure if I even inserted the new code in the correct way or into the correct spots. Here's what I have, please let me know what I'm doing wrong. Thanks in advance

const int NUM_SLIDERS = 9;
const int analogInputs[NUM_SLIDERS] = {A6, A7, A8, A9, A3, A2, A1, A0, A10};
String oldValues;

int analogSliderValues[NUM_SLIDERS];
int oldAnalogSliderValues[NUM_SLIDERS];
void setup() { 
  for (int i = 0; i < NUM_SLIDERS; i++) {
    pinMode(analogInputs[i], INPUT);
    oldAnalogSliderValues[i] = analogSliderValues[i] = analogRead(analogInputs[i]);
    if(abs(oldAnalogSliderValues[i] - analogSliderValues[i]) <= 2) analogSliderValues[i] = oldAnalogSliderValues[i];
    oldAnalogSliderValues[i] = analogSliderValues[i];
  }

  Serial.begin(9600);
}

void loop() {
  updateSliderValues();
  sendSliderValues(); // Actually send data (all the time)
  // printSliderValues(); // For debug
  delay(10);
}

void updateSliderValues() {
  for (int i = 0; i < NUM_SLIDERS; i++) {
     analogSliderValues[i] = analogRead(analogInputs[i]);
  }
}

void sendSliderValues() {
  String builtString = String("");

  for (int i = 0; i < NUM_SLIDERS; i++) {
    builtString += String((int)analogSliderValues[i]);

    if (i < NUM_SLIDERS - 1) {
      builtString += String("|");
    }
  }
  
  if(oldValues != builtString) Serial.println(builtString); oldValues = builtString;
}

void printSliderValues() {
  for (int i = 0; i < NUM_SLIDERS; i++) {
    String printedString = String("Slider #") + String(i + 1) + String(": ") + String(analogSliderValues[i]) + String(" mV");
    Serial.write(printedString.c_str());

    if (i < NUM_SLIDERS - 1) {
      Serial.write(" | ");
    } else {
      Serial.write("\n");
    }
  }
}

Is it possible that the potentiometers being used fluctuate between values? Check with the debug function to see if there's a slight change in volume even when the potentiometers are not being used. You could implement a function in the code that only sends slider values when the change is significant enough (when the potentiometer is actually being adjusted).

However, please note that for the Deej program to function correctly, values must be sent continuously. Otherwise, it won't respond at all. In other words, if a potentiometer is not being used, always send a fixed value. Only update this fixed value when the change is significant enough to ensure that you are actually adjusting the potentiometer.

I was under the impression that that's what the code adjustments in #52 were accomplishing.

But again, I'm not sure if I added the code to the correct spots in the code I posted earlier.

Give this build a shot #146. Let me know if it works for you.

Thanks for getting back to me. Unfortunately I tried the new deej.exe but the same issues occured and theres now a considerable delay between moving a slider and the volume actually changing.

Not sure if it makes a difference or not but I'm running 9 pots on my deej.

Please let me know if there are any additional steps to try.

Thanks again

@BolSadguy what version of windows are you running? Also, would you mind uploading your logs file? It should be in the same folder as where you ran the latest deej build. I'll take a look in a few hours. ☺️

[michaelwschultz]

@BolSadguy another thing that would be helpful is running powercfg /requests after opening your Powershell as administrator. This should tell you which applications or hardware are preventing your machine from sleeping currently.

Make sure you have your Deej plugged in and the new build running.

[BolSadguy]

@michaelwschultz Sorry for the late response.

I'm running Windows 11 Home. I've attached the log file below.

deej-latest-run.log

I tried the powershell command as well and didn't notice anything abnormal (in fact, the output was exactly the same when i tried it before and after disconnecting my deej and terminating the deej executable).

One thing I did notice is that with the deej disconnected and the executable still running, the pc was still being woken up. So I don't believe its an issue with my sliders.

Appreciate your time and assistance

[michaelwschultz]

Since you mentioned that your device was unplugged and the device was still being woken up, I tend to think it isn't a Deej issue. Perhaps it's another device?

The output from that terminal command should have looked like this.

DISPLAY:
None.

SYSTEM:
None.

AWAYMODE:
None.

EXECUTION:
None.

PERFBOOST:
None.

ACTIVELOCKSCREEN:
None.
