Hello, I have run into an error that im not sure whats causing it. I have went in and wrote serial.println's into a lot of my functions just to see whats happening, not finding much, will post the output as well.

I am GUESSING that maybe it's caused by volumegain 1.17? Maybe it doenst go above 1.0? Not sure what would cause that unless in my float i did something wrong. If so ill post the audio code (float and variable) to see if you guys can help

however if its not a volume gain problem i am totally lost

Now im thinking its either volume, or the playwav command (playwav has always worked before, i just added new entries to the case list) OR im complelty out of it and don't know what im saying lol.

Any help would be appreciated.

gfvalvo · October 5, 2021, 5:25pm

Run the Exception Decoder.

shaw.isabel.krystal · October 5, 2021, 5:29pm

I would use that however I'm not using arduino ide. I'm using vscode and platform io and last time I trued opening my platform io project in the ide it wouldn't build

shaw.isabel.krystal · October 5, 2021, 5:35pm

I was able to run it from the firmware.elf file platform io generated. this is the result

which is odd because none of these things have given me errors before i didn't even touch half of these i literally just added a couple more cases to my switch list

shaw.isabel.krystal · October 5, 2021, 5:38pm

And these i have no idea why they arent working

From: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/fatal-errors.html

This seems relevant, likely trying to dereference the NULL pointer.:

shaw.isabel.krystal · October 5, 2021, 6:01pm

Ok that understandable, now the question is exactly what is trying to call a null value?

Danois90 · October 5, 2021, 6:32pm

If a pointer points to nothing, accessing that nothing will cause an error. As the exceptions decoder suggests the error is at line 2767 in pa-ci1.ino

shaw.isabel.krystal · October 5, 2021, 6:34pm

Let me go check that line quick I'll post the output If I don't see immediate problems with it

shaw.isabel.krystal · October 5, 2021, 6:41pm

The line in question i am putting in {{{ }}} because i don't know how to bold it but it is an else line i have included the above and below statements.

preferences.begin("paci_check", false);
    // preferences.putBool("NeedsBootstrap", cfg.is_task_bootstrapping);
    // is_task_bootstrapping = preferences.getBool("NeedsBootstrap", false);
    is_task_bootstrapping = cfg.is_task_bootstrapping;
    if(preferences.getBool("SoftReset", false)) {
      // no startup sound after soft reset and remove the SoftReset key
      snoozeUntil=preferences.getLong64("SnoozeUntil", 0);
      preferences.remove("SoftReset");
      preferences.remove("SnoozeUntil");
   {{{ } else { }}}
      // normal startup so decide by M5CPACI.INI if to play startup sound
      if(cfg.snd_warning_at_startup) {
      playWAV(paci, paci_vol); Serial.println("GOT TO STARTUP SOUND");
      }
      if(cfg.snd_alarm_at_startup) {
        play_tone(660, 400, cfg.alarm_volume);
        delay(500);
      }

Not seeing any problems really....not sure how to proceed

shaw.isabel.krystal · October 5, 2021, 6:49pm

Think i just found it

      playWAV(paci, paci_vol); Serial.println("GOT TO STARTUP SOUND");

im using a variable there, but i dont see how that is causing a problem. (its global var) here is the definition for those to varables.

char paci = 'z';

int paci_vol = 3.0;

did i not define them right? the z should be updating to another case switch the second the device hits the void setup() one line down from power on.

Danois90 · October 5, 2021, 6:50pm

You are assigning a floating point value to an integer:

int paci_vol = 3.0;

shaw.isabel.krystal · October 5, 2021, 6:52pm

Oh dang! Your right. OK I only know how to do floats is there a better way to do volume instead of a float value that way I can use the variable?

Danois90 · October 5, 2021, 6:58pm

Sorry, but "your" code is too advanced for you to not know such basic stuff.

gfvalvo · October 5, 2021, 7:11pm

The EXCVADDR value certainly indicates that you're dereferencing a NULL pointer. But, it wouldn't hurt to sprinkle in some checks of maximum stack usage at strategic places: https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/system/freertos.html?highlight=water%20mark#_CPPv427uxTaskGetStackHighWaterMark12TaskHandle_t

shaw.isabel.krystal · October 5, 2021, 7:13pm

OK so it was the variable. I just need to redefine the control to not be a float and hopefully that will sort it out

Danois90 · October 5, 2021, 7:13pm

If it's open source, where is the code?

No, mismatching types will not sort a null pointer issue.

shaw.isabel.krystal · October 5, 2021, 7:14pm

Haven't finished it yet when it's finjshed I'll be putting it up on github
Are that nieve to as where is the code when I'm obviously still working on it?

gfvalvo · October 5, 2021, 7:26pm

Besides, implicit conversion works just fine.
