It can communicate with host devices according to HID protocol, upload and send information, and also receive information sent by host devices to perform corresponding actions.<\/strong><\/span>
\nThe multi button USB microphone has multiple buttons, and the effective operation of each button can upload the corresponding key code.
\ncharacteristic
\n\u25cf This product can be used for Windows, Linux, Android, and Mac operating systems.<\/span>
\nSupports USB-HID communication protocol and is a driver free USB audio device.<\/span>
\nCompliant with PTT (Push to talk) specifications, upload key codes when PTT is pressed and released.<\/span>
\nIn addition to the PTT button, this device also has multiple buttons that can upload key codes when pressed.<\/span>
\nThe upper computer can obtain the key code values of the corresponding keys by reading HID functional registers,<\/span>
\nYou can also obtain the corresponding key value by reading the HID report message.<\/span>
\nThe upper computer can send messages in protocol format for the microphone to receive and process.<\/span>
\nSupports a sampling rate of 44.1kHz.<\/span>
\nYou can choose to turn off the microphone or speaker separately in single channel audio mode.<\/span>

\nHID transmission key value
\nObtain the key code value of the corresponding button by reading HID functional registers:
\nThe USB microphone device has four built-in 8-byte input registers, namely IR0-IR3,
\nWhen the PTT button is pressed, the bit 3 in the HID input report HID_IR1 (offset 0x01) changes from 0 to 1,
\nWhen the PTT button is released, bit3 in the HID input report HID_IR1 (offset 0x01) changes from 1 to 0,
\nWhen pressed, the register message is 0x00 04 00 00;
\nWhen released, the register message is 0x00 00 00 00.<\/p>\n

Obtain the corresponding key code value by reading the HID report, such as:
\nWhen the PTTbutton is released, upload 8-byte data: 0x00 00 17 00 00 00 00 00;<\/span>
\nWhen the PTT button is released, upload 8-byte data: 0x00 00 00 00 00 00 00 00;<\/span>
\nWhen the K1 button is pressed, upload 8-byte data: 0x00 00 00 6A 00 00 00 00 00.<\/span>
\nWhen the K2 button is pressed, upload 8-byte data: 0x00 00 00 6B 00 00 00 00 00.<\/span>
\nWhen the K3 button is pressed, upload 8-byte data: 0x00 00 00 6C 00 00 00 00 00.<\/span><\/p>\n
