Using Audio Tools with FreeRTOS

[jay6621]

I am trying this well developed library along with tasks on dual core in arduino IDE, I am using Lyrat 4.3 (ESP32 + ES8388)
But I am only getting boot loop. Here is my code I tried both cores with same results.

#include "AudioTools.h"
#include "AudioLibs/AudioKit.h"
#include "AudioCodecs/CodecAACFDK.h"

AudioKitStream kit;    
AACEncoderFDK *fdk=nullptr;
AudioEncoderServer *server=nullptr; 

TaskHandle_t Task1;
TaskHandle_t Task2;

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

  // setup and configure fdk
  fdk = new AACEncoderFDK();  
  fdk->setAudioObjectType(2);  // AAC low complexity
  fdk->setOutputBufferSize(1024); // decrease output buffer size
  fdk->setVariableBitrateMode(2); // low variable bitrate

  server = new AudioEncoderServer(fdk,"WIFI SSID","WIFI PASSWORD");

  Serial.println("starting AudioKit...");
  auto config = kit.defaultConfig(RX_MODE);
  config.input_device = AUDIO_HAL_ADC_INPUT_LINE1;
  config.sample_rate = 8000; 
  config.bits_per_sample =16;
  config.default_actions_active = false; 
  config.channels = 1; 
  config.sd_active = false;
  config.pin_mck = 0;
  config.pin_bck = 12;
  config.pin_ws = 10;
  config.pin_data = 9;
  config.pin_data_rx = 11;
  kit.begin(config);
  Serial.println("AudioKit started");


  xTaskCreatePinnedToCore(
             Task1code, /* Task function. */
             "Task1",   /* name of task. */
             10000,     /* Stack size of task */
             NULL,      /* parameter of the task */
             1,         /* priority of the task */
             &Task1,    /* Task handle to keep track of created task */
             0);        /* pin task to core 0 */
  xTaskCreatePinnedToCore(
             Task2code,  /* Task function. */
             "Task2",    /* name of task. */
             10000,      /* Stack size of task */
             NULL,       /* parameter of the task */
             1,          /* priority of the task */
             &Task2,     /* Task handle to keep track of created task */
             1);         /* pin task to core 1 */

}
void Task1code( void * pvParameters ){
 Serial.print("Task1 running on core ");
  Serial.println(xPortGetCoreID());

  for(;;){
    server->doLoop();
  }
}


void Task2code( void * pvParameters ){
  Serial.print("Task2 running on core ");
  Serial.println(xPortGetCoreID());

  for(;;){
    Serial.print("Woohoo multi tasking with Audio Tools !!");
    delay(7000);
  }
}
// Arduino loop  
void loop() {

}

and so on......

I searched about RTOS and dual core programming with audio tools here but didn't find anything relevant, So creating a new discussion about why this is getting crashed ? pardon me if I am wrong.

Not sure what you are doing wrong, but my first guess would be that you did not pay attention to the available vs the requested RAM.
I'm usually prefering to use this library instead of the ugly c calls.
