This repository provides Arduino-based examples and setup instructions for the LilyGO T-Display S3 board (ESP32-S3 with ST7789 TFT display). It demonstrates core functionalities including TFT graphics rendering, button input handling, backlight control, and ESP-NOW wireless communication. The architecture consists of standalone Arduino sketches (.ino files) that share common configuration headers and resource files. Each example is self-contained and targets specific use cases: image display with progress bar (HotHead), backlight dimming (HotHead_DimmerNEW), simplified graphics (HotHead_2025), bidirectional button state sharing via ESP-NOW, and a basic serial test. The repository emphasizes hardware-specific configuration through header files that define display initialization, board settings, and embedded image resources.
The LLM identified 2 files worth highlighting for reuse:
A header file that enables easy TFT display configuration selection by uncommenting the line matching the hardware. Isolates display setup logic from sketches, allowing reuse across projects with minimal modification (only changing the uncommented line). Demonstrates a clean pattern for managing multiple display configurations in embedded projects.
Contains a bitmap image stored in flash memory (PROGMEM) with conditional definitions for AVR, ARM, and PIC32 portability. Embodies the pattern of embedding graphical resources in microcontroller firmware, allowing the same header to be used across different architectures without modification. Includes metadata about the source image and memory usage.
