Hid Volume Control, 目前，windows是否有办法让hid设备以百分比的方式设置系统音量？ Hi All, Yes i am very new , just got my Arduino Leonardo two weeks ago. Very conveniently, this volume control's "firmware" can be updated any time since it's connected to my PC through USB anyway. devices) # Type lowercase 'a'. The volume control button is treated as a separate category of function called "consumer control" rather than "keyboard" in the HID, so you cannot use the USB keyboard library in the Arduino to press the volume control button. I build an HID (Human Interface Devices) Media Controller with Arduino which can connect to the laptop wireless via Bluetooth. By simply moving your hand closer or further away from the sensor, you can adjust the volume up or down, making it incredibly easy to control your media without even touching the keyboard. I Got the keycodes for those buttons in USB HID Usage table . Explore Bluetooth specifications and documents to enable seamless connectivity, including profiles like Volume Control Profile for enhanced audio device management. The HID command (0xE9, 0xEA) are defined as "volume increment" and "volume decrement". h> Encoder myEnc(3,2); const int pinLed = LED_BUILTIN; const int pinButton = 12; int bulbPin = 9; int oldPosition = -999; boolean STM32 USB HID keyboard std 101 key with optional led support and volume media control implementation It's a sample SW4STM32 project running on STM32Dicovery F4 board stared from CubeMX "HID" mouse code, import usb_hid from adafruit_hid. 0 and higher, the Android Bluetooth stack lets a source set an absolute volume, giving users accurate control over audio volume. ) for smartphone My problem is the exactly the same as the original post. pdf（hid报告描述符官方手册，在移动硬盘中有保存）HID_CONSUMER_PLAY_SHIFT的移位值就需要通过配置内核的相应的。 1. ) This was tested with: Arduino Leonardo (already used as a macro keyboard, using an old PS/2 keyboard. The thread is here: Want to create bluetooth audio control (volume up/down, play, pause, etc. As we know, we use keyboards for a variety of tasks, but there are some keys that we use more frequently than others, particularly those for media control and adjusting brightness. You can build your own devices that act like remote keyboards and HID devices for nearly any mobile device or computer with Bluetooth LE and the Adafruit HID library in CircuitPython! Encoder Volume control with Arduino LEONARDO Potention meter is applied for HID volume control. Volume Knob This firmware enables the USB Knob to control the volume of your computer. This project demonstrates using a rotary encoder as a multimedia volume control and mute switch for your computer. For that reason, many of these controllers implement both Audio and HID classes, usually so you can attach buttons to the DAC and control the volume in the OS via HID. pdf，找到采用的。 （公司的hid报告描述符配置）_usb hid控制音量 Pro Trinket can function as both a USB HID keyboard and mouse at the same time with the introduced Arduino library. Ultimately I ended up with a simple gadget that now sits on my desk and allows me to control the PC volume. Contribute to mrdavidjwatts/USB-Volume-Control development by creating an account on GitHub. 1 HID USAGE TABLE CONVENTIONS. As far The HID controller is clearly better for volume control than using KEY1/KEY2 with any device such as I post below and you can make your own with an microcontroller but with KEY usage you can make extra buttons to bind with available functions on the radio. 5 — all of 1. A lot of your work would involve writing the correct HID descriptors for your composite USB device. When someone hits say a key on your device you send the HID report which then comes down and changes the volume and everyone is happy. Each USB frame is 1ms, and the Teensyduino USB keyboard code requests the interval to be every frame. This article provides a step-by-step guide on writing an Arduino function to map volume up and down to specific pins. Descriptors can be easily modified to disable master volume control if required (one byte - bmaControls (0) in Feature Unit descriptors) Volume Increment and Decrement are defined in HID Usage Tables as Retrigger Control, specified to "trigger a repeating event as long as it is asserted" (3. We neither need nor condone the use of force in our work here. By turning the knob, you can increase or decrease the volume, while pressing the knob will mute or unmute the sound. ==Welcome to Q Research General==We are researchers who deal in open-source information, reasoned argument, and dank memes. Learn how to control volume using Arduino and HID. 0xc0 // End Collection }; // Table for USB HID "Consumer Control" (for audio volume control, etc. Two new macro keys were assigned for testing audio volume up / down).

Hi All, I wanted to implement functionality for the volume up/ volume down/ mute etc. Having ADC and sound generation ability it should be possible to control volume of any audio source. 先查找HID Usage Tables_hut1_4. 我们基于原来的自定义HID进行信息修改，实现一个音量增减和当前播放停止开始的HID设备，当然由于我们是虚拟的HID设备，故这些按钮的信息是通过应用层的按钮实现，故这里是一个虚拟的按键，不同于我们如耳机上的真实按钮，不过功能都是一样的。 Enable an HID with parameters to do volume up, down, mute, track control etc. Windows XP volume control very sensitive. You can use Bluetooth LE running in CircuitPython on the Circuit Playground Bluefruit to emulate a keyboard to send wireless volume up/down, mute, Play/Pause commands! Works with any mobile device or Bluetooth LE equipped computer. Actually emulating a keyboard to control sound internally via software is also possible via USB port using HID routines. Is this true that you always have to use the consumer control data to send volume up or down? 文章浏览阅读6. Do not disassemble the device or remove the seal label from the device, doing so will void the product warranty provided by Fujian Newland Auto-ID Tech. May 20, 2025 · So I did, or rather I designed an "easy-bake" external volume controller with a proper rotating knob to use alongside my existing steering wheel volume switches. It's an STM32-based full-speed USB 2. The rotary encoder can be used to increase/decrease the volume or mute it. keyboard import Keyboard from adafruit_hid. So it can make lots of bit volume change. So I was thinking just add the correct items int the USBAPI. This will function similarly to the volume up and volume down buttons on a keyboard; Windows will see the volume knob turn and will program the volume control correspondingly (whether it is a hardware or software volume. It seems like Microsoft Windows has defined this a 2% volume step, and that it cannot be changed without running some specialized software. 一旦控制盘发生了移动，循环代码将开始执行。 如果控制盘向上移动，那么循环将会执行MEDIA_VOLUME_UP命令，直到系统音量与控制盘位置相匹配。 如果控制盘向下移动，循环将改为执行MEDIA_VOLUME_DOWN命令。 该命令是使用HID项目API的 Consumer.
