- DAC Chip :
- TI PCM51XX/TAS57XX DAC (PCM51XX are stereo DAC in TSSOP package and TAS57XX are class-D amp in HTSSOP package. Both have i2s input and i2c control)
- TI PCM5102A DAC (Very basic stereo DAC WITHOUT i2c control. Use this option if you only want i2s out like for a MAX98357)
- TI PCM5102A DAC (Very basic stereo DAC WITHOUT i2c control)
- Infineon MA120X0 (High power class-D amp in QFN package)
- Analog Devices ADAU1961 (Stereo DAC with multiple analog inputs in LFCSP package)
- Analog Devices MAX98357 (Very popular basic mono AMP without i2c control)
- DAC I2C control interface : Choose GPIO pin of your I2C line and address of the DAC. If your DAC doesn't support I2C (PCM5102A or equivalent), put unused GPIO values.
- I2C master interface : GPIO pin of your DAC I2S bus.
- DAC interface configuration : Configure specific GPIO for your DAC functionnalities. If you use a MAX98357 with PCM5102A config, don't connect the SD pin to master mute. (PCM5102A logic is inverted)
- DAC interface configuration : Configure specific GPIO for your DAC functionnalities. Use `?` to have more info.
- <b>ESP32 DSP processor config :</b>
- DSP flow : Choose between Stereo, Bassboost, Bi-amp or Bass/Treble EQ. You can further configure it on the ESP web interface/
- Use asm version of Biquad_f32 : Optimized version of the DSP algorithm only for ESP32. Don't work on ESP32-S2

GPIO number to control mute/mode. This require a special resistor to select the correct mode.
You need to put a serie resistor to select the mode (GPIO --> Resistor --> SD):
LEFT only : 0ohm (direct connection)
RIGHT only : 220Kohm
(L+R)/2 : 1Mohm
Refer to Analog Devices' doc for more infos.
This is labeled "SD" on chip/boards.
