Segger introduces audio class for USB devices
Audio applications, such as conferencing systems, speakerphones, headphones or USB-to-audio adapters using the USB stack emUSB-Device, says Segger.
If the target device incorporates or attaches to microphones, speakers, headsets, and/or musical instruments, the USB interface is a way to stream the audio data to or from the host.
The audio class is a component of Segger’s USB stack emUSB-Device. The emUSB-Device is a USB device stack specifically designed for embedded systems. It runs on any microcontroller and is platform-independent.
The flexible device stack enables the creation of multi-class devices using nearly any combination of the available USB classes, explains Segger. emUSB-Device provides classes for media transfer protocol, mass storage device, CD-ROM, audio, human interface device, CDC-ACM (serial port communication), IP-over-USB, and printers. A bulk communication class delivers efficient, high-bandwidth peripherals.
The emUSB-Device complies with the USB-standard.
Trial packages targeting Segger’s emPower board is available for download.
