RK3588S demo resource

This directory contains the LVGL demo binary deployed on RK3588S devices by install.sh.

Files

• demo — prebuilt LVGL UI binary installed to /usr/bin/demo on RK3588S boards

Source

Current binary source on the build machine:

• /home/sts/share/小屏demo开发指南/lvgl源码/lv_port_linux_v2/lv_port_linux/build/bin/demo

Purpose

This demo provides the small-screen UI used on RK3588S devices, including FIFO-based control through:

• /tmp/lvgl_cmd

Supported commands expected by the current clawd RK3588 LVGL backend include:

• show_text:AP
• show_text:Conn
• show_text:Err0
• show_text:<PIN>
• show_time

Install behavior

During install.sh, if /proc/device-tree/model matches RK3588S, clawd will:

1. Back up existing /usr/bin/demo to /usr/bin/demo.clawd-bak if not already backed up
2. Install this demo binary to /usr/bin/demo

Notes

• The binary is hardware-specific and intended for RK3588S boards.
• Replacing the binary should be done together with verification of /tmp/lvgl_cmd behavior and screen rendering.
