BLE - HID 滑鼠

材料准备

  • AmebaD [AMB21 / AMB22 / AMB23 / BW16] x 1

  • 支援 BLE 的设备 [Windows / Linux / MacOS / Android

范例说明

介绍

在此范例中，RTL8722 开发板用来模拟使用 BLE 连接的 HID 滑鼠。

流程

Open the example, “Files” → “Examples” → “AmebaBLE” → “BLEHIDMouse”.

1

Upload the code and press the reset button once the upload is finished. Immediately after reset, the board will begin BLE advertising as “AMEBA_BLE_HID”. On your host device, go to the Bluetooth settings menu, scan, and connect to the board. You should ensure that the connection process is completed before proceeding. On Windows, ensure that any driver installation is finished, and the board shows up in the Bluetooth menu under the “Mouse, keyboard & pen” category.

2

在 Android 上，确保为开发板启用“Input device”。

3

After the Bluetooth connection process is completed, the board is ready to send mouse input to the host device. Connect digital pin 8 to 3.3V to start sending input, and connect to GND to stop. You should see the mouse cursor move around four points in a square, performing right and left clicks, and scrolling up and down.

程式码说明

如何定义鼠标输入取决于主机设备。某些系统（例如Android）可能不支持所有鼠标按钮输入功能。
