What it is

A community-driven documentation and example repository for the ESP32-2432S028R (nicknamed "Cheap Yellow Display" or CYD), a ~$15 ESP32 board with built-in 320×240 LCD touch screen, SD card slot, and USB. It provides Arduino sketches, Rust firmware examples, 3D-printable cases, and project templates to address poor upstream documentation for this specific hardware. Polyglot monorepo: Examples/ contains Arduino sketches and alternative library examples (Adafruit_ILI9341, bb_spi_lcd), DisplayConfig/ holds hardware setup files (User_Setup.h for TFT_eSPI), top-level Cargo.toml targets Rust-on-ESP32 using esp-idf-svc, and 3dModels/ organizes community CAD files by contributor.…

Start here

Open these first:

• DisplayConfig/User_Setup.h — Core hardware configuration file that defines GPIO pins, SPI settings, and display parameters—must be understood before any…
• Examples/Basics/1-HelloWorld/1-HelloWorld.ino — Entry point demonstrating minimal setup; shows how to initialize the display and render text, foundational for all other…
• Examples/Basics/2-TouchTest/2-TouchTest.ino — Demonstrates touch screen input handling; critical for understanding user interaction patterns on this hardware.
• Examples/ESP-IDF/LCD/components/LCD/lcd.c — Low-level LCD driver implementation in C; controls SPI communication and display initialization for ESP-IDF projects.
• .github/workflows/arduino-cli.yml — CI/CD pipeline that validates example sketches; reveals build requirements and expected Arduino board configuration.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

git clone https://github.com/witnessmenow/ESP32-Cheap-Yellow-Display.git
cd ESP32-Cheap-Yellow-Display
# For Arduino examples: Install Arduino IDE + ESP32 board manager
# For Rust examples: cargo build --release (requires rustup + esp-idf-tools)

Daily commands:

Arduino: Open Examples/*.ino in Arduino IDE, select ESP32-2432S028R board, set TFT_eSPI config in DisplayConfig/User_Setup.h, compile and upload via USB. Rust: cd into example dir, cargo build --release, fla…

Key cautions & unknowns

• Could not verify tests from the available repository evidence
• Critical: Display pin mapping in User_Setup.h is hardware-revision-dependent; CYD2USB variant has different pins (see DisplayConfig/CYD2USB/User_Setup.h). Rust-specific: display-interface pinned to 0.4.1 (not…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
