Audio on Intel Edison

Jump to solution

Would anyone be able to help me with my project? I would like to perform the following with my edison chip and its arduino breakout board:

1. Store audio files on an SD card that is inserted into the board.

2. Using the edison as an audio player, I would like to output a varying voltage source for an LED light board, connected to one of the outputs on the board.

3. Eventually, I would like to be able to download new audio files to the SD card, using WiFi.

Hi ClearTech,

There are some guides from Intel and all over the Internet that you might find useful. First, check the http://download.intel.com/support/edison/sb/edisonaudio_332434001.pdf Edison Audio Setup Guide for general information, probably you'll need to check this guide more than once. To play music with your Intel Edison you can take a look at this guide http://www.instructables.com/id/Playing-music-with-your-Intel-Edison/ http://www.instructables.com/id/Playing-music-with-your-Intel-Edison/, it consists in playing music via external speaker using a USB sound card. There's also this guide to play audio via Bluetooth using A2DP, https://software.intel.com/en-us/articles/play-audio-from-your-intel-edison-via-bluetooth-using-adva... https://software.intel.com/en-us/articles/play-audio-from-your-intel-edison-via-bluetooth-using-adva.... About managing files and data from an SD card with your Edison, there's a lot of information available in the Community, here's something for you to start /thread/55914 https://communities.intel.com/thread/55914.

That all makes sense so far. I can establish bluetooth comms and WiFi. When I get to this stage on the instructables page however, it doesn't seem to work like it should I'm sure I'm missing something:

Step 3: Installing Packages

Package Manager:

You need to configure your opkg repository to include the following lines:

src/gz all http://repo.opkg.net/edison/repo/all http://repo.opkg.net/edison/repo/all src/gz edison http://repo.opkg.net/edison/repo/all http://repo.opkg.net/edison/repo/all src/gz core2-32 http://repo.opkg.net/edison/repo/all

Do so by typing:

vi /etc/opkg/base-feeds.conf

By typing this above line in, it doesn't seem to automatically configure my opkg repository. Do I need to follow the path and manually enter all of the opkg lines? My WiFi connection is good, so that doesn't seem to be the problem.

Hi ClearTech,

Yes, you'll need to enter those lines by yourself. The command vi /etc/opkg/base-feeds.conf creates or opens (in case it already exists) a file called base-feeds.conf in the /etc/opkg path that you can then edit (vi is a text editor). If you're not sure how to use VI, check the following guide https://www.cs.colostate.edu/helpdocs/vi.html https://www.cs.colostate.edu/helpdocs/vi.html.

Pablo
