LAFVIN Pico 2 Dev Kit — Interactive Display Demo - https://www.amazon.com/dp/B0G7F6Y1BB

An interactive hardware showcase for the LAFVIN Pico 2 Development Kit, driving a 3.5" ILI9488 480×320 TFT display over SPI from the RP2350 microcontroller. Uses a framebuffer architecture adapted from Tutorial-OS to render graphics into an RGB565 shadow buffer in SRAM, then push frames to the display as RGB666 over SPI.

What It Does

Six interactive scenes demonstrate the board's peripherals:

Scene	Content
Splash	Boot screen with system info, color circles, touch detection status
Colors	Tap or joystick to cycle through 8 solid color fills with labels
Shapes	Rectangles, circles, triangle, rounded rects, line starburst
Gradients	Horizontal, vertical, and full-rainbow gradient fills
Text	8×8 bitmap font rendered at 5 different scales, full character set
System Info	Live readout of touch position, joystick ADC values, button state

Controls

• Joystick left/right — Navigate between scenes
• Touch tap — Next scene (cycles colors in the Colors scene)
• K2 button (GP14) — Audio ON (ascending chime confirms)
• K1 button (GP15) — Audio OFF (immediate silence)

Navigation sounds only play when audio is enabled. A status bar at the bottom of every scene shows audio state and current scene number.
