PCM5102A I2s DAC
Optional: No ADS (pots) and no rotary by default. If you want to use ADS and rotary uncomment line 17 //#define ads_ok
ADS1115 (I2c ADC)
4 pots (B10k)
1 Rotary encoder
Gerber file attached into file ads1115 module.rar
IDE: Arduino 2.3.5
Boards: Expressif Systems 3.2.0 Board: ESP32S3 Dev module Partition: Huge APP 3MB or custom CSV
Libraries:
Sequencer Timer - Modified version of uClock. (macsbug solution). I'm testing an alternative. Commented funcs included. Random boot :(
TFT - Arduino_GFX_Library
Select "Huge APP 3MB" partition.
If samples don't fit into flash you can use custom partition included to get 3.5MB You can replace the sounds changing code "easily". To get .c from sound files I use wavtocode (windows) https://colinjs.com/software.htm#t_WAVToCode Sounds specs: 44100hz, 16Bit, Mono

- Add sample files names instead of sample number (code is ready)
- MIDI. Not tested.
- MIDI BLE. Waiting update. Now can't compile.
- Add a reverb code (I tried a lot but no good result) or some other audio FX.
- Solve issues
- Finish this read me.
Target is to use SD card instead of flash.
- Use 8MB PSRAM
- Wav file explorer
- PSRAM manager
