DM320 Platform accessories

From The Neuros Technology Wiki

Jump to: navigation, search

The DM320 Platform is capable of supporting a dizzying array of peripherals, accessories, and hacks; far more than any one company could ever hope to support on its own. Here's where you come in. As Neuros products reach wider audiences, the number of creative applications of the hardware will blossom -- so post your ideas, experiments, drivers and applications to this page.

Below is a list of peripherals that might be supported by the DM320 platform. Some, like USB Mass Storage devices, will recieve official support and become tightly integrated into the Neuros application; this list will grow when a class or model of an accessory has working code, both at the OS and application levels, contributed by the community. Other devices, particularly home-made hacks, will not recieve official support; it's up to the community to document and support such devices. As the number of devices at each level of support grows, this page will be split to deal with them as needed.

USB Add-ons

"If it doesn't work on Linux, it doesn't work on a DM320 device."

Most DM320-based boards are equipped with some form of USB Host, be it an implementation of USB-OTG or USB Hi-Speed support. Being based on Linux, we have a fairly complete set of drivers that need only be ported -- and perhaps not even that. However, it's possible that a device that works on a desktop simply can't on a DM320 board, so keep that in mind before buying expensive peripherals.

One important consideration is the difference in the availability of powered USB ports on DM320 boards. Many devices draw at or over the maximum rated power output of a USB connector. Being battery-powered, most portable implementations of the DM320 platform can't support overdraw for long, if at all. More details on this can be found on a per-product basis as they emerge.

USB Mass Storage

This category includes USB hard drives, flash drives, external card readers, and many other USB peripherals. External storage will be tightly integrated throughout the entire interface across all DM320 products, and every standards-compliant mass storage device should be supported out-of-the-box.

802.11 Wireless

We're working hard on supporting a lot of 802.11g dongles, and integrating their configuration and use into the app. These dongles are cheap -- they've been seen regularly for free (after rebate) on many places across the internet. Considering how much wireless internet access could rock out in wireless-blanketed areas like university campuses and hotels, adding their functionality to Neuros products is a high priority.

USB Audio

This class includes everything from breakout boxes to self-contained USB microphones. For this device class, support hinges on two things: the device must be compatible with the ALSA drivers on a desktop Linux solution, and a low-overhead Media Framework plugin must be written to make ALSA act as a sample source (for recording devices) or sample sink (for playback devices).

Digital (or analog) TV tuners

There are a number of these for DVB-T already for Europe. and ones for ATSC (North America) are starting to appear. Research is ongoing into the compatibility with the Neuros products.


FM (or AM) Radio receivers

Research is ongoing into the compatibility of these with the Neuros Products.

Other Accessories

Mobile Video Recording

The use of most camcorders and portable cameras should be trivial on products like the 442v2, because it sports composite video in as well as an audio line-in.

Microphones

At this point, no Neuros product will include a microphone preamp. Thus, in order to record from most mics, you'll need to obtain an external preamp and use it with the line-level input. This decision allows us to offer smaller, higher-quality devices with substantially less power usage. In addition, an external preamp will yield significantly better recordings than one placed inside the electrically noisy case.
