arduino-audio-driver's Introduction

Arduino Audio Driver

I was never quite happy with my AudioKit project, that was a quick and dirty adaptation of the Espressif IDF Drivers for Arduino.

In this project I finally implemented some clean and simple C++ classes. This reduced the complexity considerably and increased the flexibility tremendously!

The goal of this project is to provide an easy API to configure different audio codec chips. After setting up the codec, you can use the I2S functionality provided by your microcontroller.

Supported audio codec chips are e.g

AC101
ES8388
ES8311
CS43l22
ES7243
etc

While you can use this library stand alone, I recommend to use it together with my AudioTools project which provides a nice integration with it's I2SCodecStream class. Further information can be found in the Wiki.

Documentation

Support

I spent a lot of time to provide a comprehensive and complete documentation. So please read the documentation first and check the issues and discussions before posting any new ones on Github.

Open issues only for bugs and if it is not a bug, use a discussion: Provide enough information about

the selected scenario/sketch
what exactly you are trying to do
your hardware
your software versions
what exactly your problem is

to enable others to understand and reproduce your issue.

Finally, don't send me any e-mails or post questions on my personal website!

Installation in Arduino

You can download the library as zip and call include Library -> zip library. Or you can git clone this project into the Arduino libraries folder e.g. with

cd  ~/Documents/Arduino/libraries
git clone https://github.com/pschatzmann/arduino-audio-driver.git

I recommend to use git because you can easily update to the latest version just by executing the git pull command in the project folder.

arduino-audio-driver's Issues

Encoding failed: Handle passed to function call was invalid

Hi, I am using the codec with Arduino Audio Tools on an Audio Kit board.

[E] AACEncoderFDK.h : 234 - Encoding failed: Handle passed to function call was invalid

I am using the streams-audiokit-webserver_aac.ino example.
I am also using the new Auduino-Audio-Driver.
I am also using the auduino-fdk-acc codec

The code builds and uploads but i get this runtime error in the serial monitor when i connect to the web server via Chrome.

Thanks

Eric

Should "library.properties" be updated with the new version #?

The Arduino IDE isn't suggesting that your libraries need to be updated even though there have been several updates since I downloaded them a few months ago.

suggest explicit braces to avoid ambiguous 'else' [-Werror=dangling-else]

Error in title compiling main stream:

for (auto &tmp : spi) {
      AD_LOGD("DriverPins::begin::SPI::begin");
      if (tmp.function == PinFunction::SD)
        if (sd_active)
          result &= tmp.begin();
      else
        result &= tmp.begin();
    }

I think that adding braces make code cleaer effectively

   for (auto &tmp : spi) {
      AD_LOGD("DriverPins::begin::SPI::begin");
      if (tmp.function == PinFunction::SD)
      {
        if (sd_active)
          result &= tmp.begin();
      else
        result &= tmp.begin();
      }
    }

Audio kit keeps rebooting

I have the ESP32 Audio kit V2.2 and I am running this code:

#include <Arduino.h>

/**
 * @brief We use a predefied board (AudioKitEs8388V1) and output_device a sine
 * with the help of the AudioTools I2SCodecStream
 * @author phil schatzmann
 */

#include "AudioTools.h" // install https://github.com/pschatzmann/arduino-audio-tools
#include "AudioLibs/I2SCodecStream.h"

AudioInfo info(44100, 2, 16);
SineWaveGenerator<int16_t> sineWave(32000);
GeneratedSoundStream<int16_t> sound(sineWave);
I2SCodecStream out(AudioKitEs8388V1);
StreamCopy copier(out, sound);

void setup()
{
  // Setup logging
  Serial.begin(115200);
  AudioLogger::instance().begin(Serial, AudioLogger::Warning);
  LOGLEVEL_AUDIODRIVER = AudioDriverWarning;

  // start I2S & codec with i2c and i2s configured above
  Serial.println("starting I2S...");
  auto config = out.defaultConfig();
  config.copyFrom(info);
  out.begin(config);

  // Setup sine wave
  sineWave.begin(info, N_B4);
}

// Arduino loop - copy sound to out
void loop() { copier.copy(); }
