LCD Touch Paint

Name: lcd_touch_paint
Author: espressif

Use this skill when the user asks for a drawing app, paint app, touch test, LCD touch demo, or finger drawing on the board's display.

The Lua script uses the on-device board_manager, display, and lcd_touch modules to initialize the panel and render strokes that follow the user's finger. It clears and redraws each frame, so no persistent buffer is needed.

Requirements

A display device declared as display_lcd in board hardware info.
An LCD touch device available on the board.

If either is missing the script prints an error and exits without retrying.

Tool Call Inputs

{
  "path": "{CUR_SKILL_DIR}/scripts/lcd_touch_paint.lua",
  "args": {}
}

The script takes no arguments; pass an empty args object.

Behavior

After launch the screen shows a blank canvas. Touching and dragging a finger draws strokes in the configured ink color; releasing lifts the pen. The script runs until it is stopped by the runtime. On startup or runtime failure it prints a single [lcd_touch_paint] ERROR: ... line which should be reported directly to the user.
