ESP32 DRUM SYNTH MACHINE (JC4827W543 C BOARD)

This is my DRUM SYNTH LOFI MACHINE for Guition ESP32 JC4827W543 (Capacitive touch model)

Video demo: https://youtu.be/qMTG5fs26MI?si=py-24suVv46LcCxw

All features from DRUM_2024_V1 are ported to this system.

I have changed buttons, LEDs, rotary encoder and OLED screen for a TFT screen with touch panel

About the board: It has a I2S DAC with amp ready to attach a speaker. In the GUI you can select:

0, external I2S DAC (default)

1, internal i2S DAC

2, Both

Hardware:

• Guition JC4827W543 C (ESP32 S3, LCD ILI9488, touch panel GT911) https://s.click.aliexpress.com/e/_EzVhSEH
• PCM5102A I2s DAC (for better sound output) or a speaker (with that tiny conector)

Software:

IDE: Arduino 2.3.2

Boards: Expressif Systems 2.0.17

Board: ESP32S3 Dev module

Necessary Libraries:

• Sequencer Timer - uClock
• TFT - Arduino_GFX_Library
• Touch panel - bb_captouch

Notes:

Can't find schematics of the board but info about pinout is avaliable throught other projects. External PINs used to wired PCM5102 module:

IO6 - I2S_WS_PIN - LCK

IO7 - I2S_BCK_PIN - BCK

IO15 - I2S_DATA_OUT_PIN - DIN

Cheat sheet style PDF V1 version is fully compatible. Added function to select audio out.

I2S PCM5102A module:

• Join solder pads near SCK pin on PCM5102A module.

• Solder pads on the back of PCM5102A module (more info)

  • H1L: FLT - Low

  • H2L: DEMP - Low

  • H3L: XSMT - High

  • H4L: FMT - Low
