Can't use a while loop after an if statement?

[theanton205]

As weird as this sounds, my spresense terminates the program in Arduino after an if statement is met. Below is my code, where it waits until a value from my accelerometer is met to then play audio. However, in order to play this audio, we need to writeFrames in a loop. So, I used a while loop to do so. This while loop, defined in the function below as "plays()" works outside of the if statement. I'm at a loss, any thoughts?

#include <Adafruit_MPU6050.h>
#include <Adafruit_Sensor.h>
#include <Wire.h>
#include <SDHCI.h>
#include <Audio.h>

Adafruit_MPU6050 mpu;

int x = 0;
int y = 0;
int z = 0;

SDClass theSD;
AudioClass *theAudio;

File myFile;
bool go = true;
bool ErrEnd = false;
int counter = 0;

static void audio_attention_cb(const ErrorAttentionParam *atprm)
{
  puts("Attention!");
  
  if (atprm->error_code >= AS_ATTENTION_CODE_WARNING)
    {
      ErrEnd = true;
   }
}

void plays() {
  while (go) {
    int err = theAudio->writeFrames(AudioClass::Player0, myFile);
    if (err == AUDIOLIB_ECODE_FILEEND) {
      Serial.println("File ended!\n");
      go = false;
    }
  }
}

void setup(void) {
  Serial.begin(115200);

  // Try to initialize!
  if (!mpu.begin()) {
    Serial.println("Failed to find MPU6050 chip");
    while (1) {
      delay(10);
    }
  }
  Serial.println("MPU6050 Found!");
  mpu.setAccelerometerRange(MPU6050_RANGE_8_G);
  mpu.setGyroRange(MPU6050_RANGE_500_DEG);
  mpu.setFilterBandwidth(MPU6050_BAND_21_HZ);

  delay(100);

  while (!theSD.begin())
    {
      Serial.println("Insert SD card.");
    }

  // start audio system
  theAudio = AudioClass::getInstance();

  theAudio->begin(audio_attention_cb);

  puts("initialization Audio Library");

  theAudio->setRenderingClockMode(AS_CLKMODE_NORMAL);
  theAudio->setPlayerMode(AS_SETPLAYER_OUTPUTDEVICE_SPHP, AS_SP_DRV_MODE_LINEOUT);

  err_t err = theAudio->initPlayer(AudioClass::Player0, AS_CODECTYPE_MP3, "/mnt/sd0/BIN", AS_SAMPLINGRATE_AUTO, AS_CHANNEL_MONO);

  if (err != AUDIOLIB_ECODE_OK)
    {
      printf("Player0 initialize error\n");
      exit(1);
    }

  myFile = theSD.open("ask_help.mp3");

  if (!myFile)
    {
      printf("File open error\n");
      exit(1);
    }
  printf("Open! 0x%08lx\n", (uint32_t)myFile);

  err = theAudio->writeFrames(AudioClass::Player0, myFile);
  theAudio->setVolume(120);
  theAudio->startPlayer(AudioClass::Player0);

}

void loop() {

  sensors_event_t a, g, temp;
  mpu.getEvent(&a, &g, &temp);

  x = g.gyro.x;
  y = g.gyro.y;
  z = g.gyro.z;

  // Serial.print("Rotation X: ");
  // Serial.print(x);
  // Serial.print(", Y: ");
  // Serial.print(y);
  // Serial.print(", Z: ");
  // Serial.print(z);
  // Serial.println(" rad/s");

  if(x >= 8 || x <= -8){
    Serial.println("plays!");
    //plays();
  }
    
  myFile.close();
  myFile = theSD.open("ask_help.mp3");
  go = true;
}

@theanton205

Do you mean that if the loop function is like below then the program works?
(plays() outside if statement)

void loop() {

sensors_event_t a, g, temp;
mpu.getEvent(&a, &g, &temp);

x = g.gyro.x;
y = g.gyro.y;
z = g.gyro.z;

plays();

myFile.close();
myFile = theSD.open("ask_help.mp3");
go = true;
}
