Wolfson Open Source eNews

Home

Welcome to the community open-source website for Wolfson Microelectronics.

This site aims to promote collaborative software development and cultivate the exchange of information and ideas within the open source community and is a central resource for developers working on open source software and Linux drivers for Wolfson devices.

Please use the menu bar to find more details of our open source projects and activities.

Wolfson also provides drivers for other operating systems. To obtain our latest driver software for these OSs or to check on the availability of new software and hardware support, please see here.

Wolfson updates in Linux v3.6

Linux v3.6 was released on Sunday. This release features initial support for Wolfson's new WM5102 and WM5110 audio hub CODECs, as well as a host of minor updates to existing Wolfson drivers.

Speaking at ELC-E: "regmap: The Power of Subsystems and Abstractions"

I will be speaking at ELC-E in Barcelona this year, with a talk entitled regmap: The Power of Subsystems and Abstractions. Slides from the talk will be available on this site once it has been presented.

WM0010 Linux driver released

An initial Linux driver for the WM0010, a compact digital signal processor that has been highly optimised for low-power audio applications. Extensive memory resources and core optimisation allow the device to manage all audio processing algorithms efficiently and autonomously, while the host processor sleeps or performs other tasks. Like all Wolfson drivers this can be obtained via our ASoC page.

WM5110 Linux driver released

An initial Linux driver for the WM5110, a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices which combines an advanced DSP feature set with a flexible, high-performance audio hub CODEC. Like all Wolfson audio drivers this can be obtained via our ASoC page. For more information on the WM5110 please see the main WM5110 product page.

WM5102 Linux driver released

An initial Linux driver for the WM5102, a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices combining wideband telephony voice processing with a flexible, high-performance audio hub CODEC.. Like all Wolfson audio drivers this can be obtained via our ASoC page. For more information on the WM5102 please see the main WM5102 product page.

Wolfson updates in 3.4

Linus released kernel version 3.4 recently. For Wolfson this release was mainly focused on framework enhancements to support next generation prouducts.

Wolfson updates in Linux 3.3

Linus released version 3.3 of the Linux kernel on Monday this week. The major new Wolfson-related features in this version of the kernel are support for the WM1811A, together with expanding support for the Wolfson audio reference systems.

TinyHAL

Earlier today I delivered a talk at Android Builders Summit on TinyHAL, a project aiming to solve some of the problems with audio system integration on Android. A copy of the slides and a little more information are available via our TinyHAL page.

WM2200 Linux driver released

Initial Linux support for the WM2200, a low power mobile CODEC with enhanced Wolfson myZone™ Ambient Noise Cancellation (ANC), has just been released. Like all Wolfson audio drivers this can be obtained via our ASoC page. For more information on the WM5100 please see the main WM2200 product page.
