Preparation

  • You will need a Windows 10 computer. Other operating systems may work theoretically, but I haven't tested them. For the purposes of this guide, I'll use my computer as an example, and unless otherwise specified, all environment setup and development compilation will assume this configuration.

Introduction ​

Why Use scrcpy ​

  • When the LCSC Taishan-RK3566-Linux Dev Board doesn't have a display, touchscreen, mouse, or keyboard, you can use scrcpy to mirror the screen to your computer for interaction.

  • Installing scrcpy is very easy, especially on Windows 10 — just download and run it.

  • Just connect the LCSC Taishan-RK3566-Linux Dev Board to your computer with a Type-C cable.

  • The screen mirroring quality and frame rate are very high.

  • And the best part? It's open source! https://github.com/Genymobile/scrcpy。

What is scrcpy? ​

scrcpy is a tool that mirrors the screen of an Android device and allows you to control it via USB or TCP/IP. It can stream both video and audio from the Android device to a computer, and you can use the computer's keyboard and mouse to control the device. No root access is needed, and it works on Linux, Windows, and macOS. Key Features of scrcpy:

  • Lightweight: It's a native application that only displays the device's screen content.

  • High Performance: Frame rates range from 30 to 120 fps, depending on the device's performance.

  • High Quality: Supports resolutions up to 1920×1080 or higher.

  • Low Latency: Delays are between 35–70 milliseconds.

  • Fast Startup: Displays the first frame in about 1 second.

  • Non-Intrusive: No need to install any software on the Android device.

  • User-Friendly: No account, no ads, and no internet required.

  • Free and Open Source: It's completely free and open-source.

scrcpy Features:

  • Audio forwarding (only for Android 11 and above).

  • Screen recording.

  • Mirroring when the device screen is off.

  • Two-way clipboard copy-paste.

  • Configurable video quality settings.

  • Camera mirroring (only for Android 12 and above).

  • Camera as a V4L2 device (only on Linux).

  • Simulate physical keyboard/mouse (HID).

  • Supports OTG mode and more.

Prerequisites:

  • Android Device Requirement: The device must have at least API 21 (Android 5.0).

  • Audio Forwarding: Requires API >= 30 (Android 11 and above).

  • Enable USB Debugging: Make sure that USB debugging is enabled on the device.

  • Additional Setting for Some Devices: On certain devices, you may also need to enable the option "USB Debugging (Security Settings)" (which is different from the regular USB debugging) to use the keyboard and mouse for control. After enabling this option, a device reboot is required.

  • Note for OTG Mode: When using scrcpy in OTG mode, USB debugging is not required.

Connecting the LCSC Taishan-RK3566-Linux Dev Board ​

Connect the LCSC Taishan-RK3566-Linux Dev Board to the computer via a USB data cable and ensure it enters Android mode.

  • Make sure your computer has sufficient power. Some computers may lack enough USB power, which could prevent the Taishan-RK3566 from booting into the system. If this happens, you can use a PD power adapter to supplement the power.

  • Ensure the USB debugging option is enabled. The Android firmware on the Taishan-RK3566 development board has ADB debugging enabled by default. You can check if it's enabled by seeing if the computer detects the ADB device.

  • Use a data cable that supports both data transfer and charging. Do not use a cable that only supports charging.

Starting scrcpy ​

Find the extracted folder and double-click scrcpy.exe to start scrcpy.

When it runs successfully, two interfaces will appear: one for the command line and the other for the Taishan-RK3566 screen mirror.
