Toggle switches, push-buttons, and a joystick button let users switch TFT display modes and control eye behaviors, achieving realistic eyeball simulation. Users can edit code or load content from a TF card to customize the TFT screen, enjoying the fun of presenting self-designed images through programming.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eFeatures:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e- ESP32 Open-Source Platform:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eModular code structure, clearly commented key functions, easy to expand.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e- SPI Full-Duplex Communication:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eTwo GC9A01 1.28-inch TFT screens are driven independently via SPI, with a simple protocol and high transfer speed.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e- DMA Dual-Buffer Technology:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eDuring GIF playback, the screen is rendered in blocks to avoid stutter .
