Extended Configuration

In the configuration you can now change any pin and the codec driver.
This makes it easier to use some custom board w/o the need to change this project.

New Settings/Improvements/Error Corrections

New/Changed AudioKitSettings.h configuration settings:

• New WORKAROUND_MIC_LINEIN_MIXED to activate/deactivate the functionality
• New WORKAROUND_ES8388_LINE1_GAIN to define the gain using the values from es_mic_gain_t
• New I2C_CLOCK_SPEED
• ES8388_DEFAULT_INPUT_GAIN is using the values from es_mic_gain_t

Improvements:

• Cleanup dependency to ets_print()
• allows gains to be overridden by platformio.ini
• More reliable determination of ESP32 processor type for S3,S2 or C3-
• Call setSpeakerActive(false) on end() to save power
• Replace ESP32 IDF calls with consistent Arduino API calls
• support i2s_active flag in config with example

Error Corrections

• Corrected compile error in example sdmmc_begin.ino (added missing semicolon)
• Prevent compile error on old ESP32 Releases

Namespace, Support for no i2s

• Using namespace audiokit
• We can use this library just to setup the codec w/o i2s
  • Possibility to to deactivate I2S with config.i2s_active = false;
  • Added example for i2s_active = false
  • Example Mozzi

dac_output, LED_BUILTIN and override pins

• Provide LED_BUILTIN for LED
• Allow to override pins in generic board_def.h when using PlatformIO
• proper support to be able to select earphones or amplifier in dac_output

Some more configuration optioins

AudioKitSettings.h supports now:

• ES8388_DEFAULT_MIC_GAIN
• AI_THINKER_ES8388_VOLUME_HACK with values 0, 1 or 2

Some Error Corrections

• Some Minor Error Corrections
• HAL to implement setSampleRate
• Update of Readme and Documentation

Breaking Changes if you use Wire1 - SDMMC

• Wire1 is now used as default to communicate with the Audio chip. This can be configured in AudioKitConfig.h
• Option to configure SPI to use VSPI AudioKitConfig.h
• Example to start SD with SDMMC
• Added Wire option in SD example

Further details can be found in the Wiki

v0.5.0: New Boards and Error Corrections

• Configuration of AI_THINKER_ES8388_VOLUME_HACK
• Support for AI Thinker 2957
• Resolve compile errors for non ESP32 Processors
• AudioKitConfig additional parameters
• Support for ai_thinker AC101 sound chip
• Compile error in output.ino example
• Error messages for unsupported samplerate

AudioKit Corrections

• move driver to src directory
• Move HAL files into audio_hal directory
• AudioKit AC101 Buttons
• AIThinker - AudioKit has no touch pins!
• set sd active by default
• rename AUDIOKIT_LOG_LEVEL to LOGLEVEL_AUDIOKIT

Support for AC101

• Support for old releases of AI Thinker AudioKit using the AC101
• Move HAL files into audio_hal directory
