Before launching into this tutorial, there are a few basic concepts you should be familiar with. If the subject of these tutorials sounds foreign to you, read about it before continuing on with this hookup guide. Hardware Overview.
The centerpiece of the MP3 Player Shield is a VS1053B Audio Codec IC. The VS1053B is a multitalented little chip. On top of MP3’s, it can also decode Ogg Vorbis, AAC, WMA, and MIDI. (It’s also capable of encoding audio, although that’s outside the scope of the MP3 Shield.
Supporting the VS1053 is a µSD card socket. which you can use to store MP3 files on. Using the Arduino SD library. it’s simple to read music files off an SD card, and stream them to the VS1053B. There’s additional circuitry on-board to level shift signals down to the 3.
3V maximum allowable by SD cards. Here’s a quick visual overview of the important connectors and other components on the MP3 Player Shield:.
In the image above, the blue labels are pins used by the VS1053 MP3 Codec IC, the red labels are used for communication with the µSD card, and the purple-labeled pins are used by both components (yay SPI !). Which Pins are Being Used.
The MP3 Player Shield requires exclusive use of a handful of pins. These pins can’t be used to interface with other devices:. D2 is connected to the data request output of the VS1053B. This pin is an interrupt, which tells the Arduino that the IC needs more music data. D6 is connected to the chip select input of the VS1053B. This active-low pin tells the chip when data is being sent to it. D7 is connected to the data chip select input of the VS1053B, which tells the chip when music data is being sent.
D8 is connected to the reset input of the VS1053B. D9 is connected to the chip select input of the µSD card. The Arduino’s three SPI data and clock pins – D11, D12, and D13 – can be used to interface to other SPI components.
They can’t, however, be used for any purpose other than SPI. Which Pins are Free. Whew! The shield does use up quite a few pins, but here are the pins still available to connect to other components. The hardware UART pins – RX and TX – on pins 0 and 1.
D5 and D10 (PWM pins!). All analog pins ( A0 through A5 ). Optional Pin Jumpers. Two pins we haven’t mentioned yet are D3 and D4, which are connected to the VS1053B’s MIDI-In and GPIO1 pins respectively. Use of these pins is optional. They’re not required for most MP3-playing functions, including the examples we’ll show in this tutorial.
To disable either of those pins, a jumper next to their label can be cut using a hobby knife. Getting Audio Out. There are two options for driving audio out of the MP3 Player Shield. The easiest, most plug-and-play option is to stick some headphones into the on-board 3. 5mm stereo audio jack.
Active (powered) speakers could also be plugged into this jack, but the VS1053B alone doesn’t have enough power on its own to drive low-impedance, passive speakers. The right and left channels, as well as the audio ground are also broken out to a 0. 1" header next to the headphone jack. You can use these pins to connect up to a speaker or amplifier input.
Line Out Warning. If you’re going to connect the speaker output to power amplifiers or circuits, make sure you read through VLSI’s Connecting analog outputs application note. The pin labeled ‘-’ next to ‘R’ and ‘L’ is connected to the ‘GBUF’ pin on the VS1053B. This pin isn’t ground, and shouldn’t be connected to ground! It’s biased internally in the VS1053B to 1. 25V.
If GBUF is connected to a line-in input on a PC, for example, it could be connected on the PC side to ground and form a ground loop. A dangerous (to the VS1053B) current loop can be created if GBUF is connected to an amplifiers ground. (From the VS10XX Analog Output App Note.
Don’t do that! The VLSI app note has some recommended circuits (see sections 3. 1 and 3.
2) to help avoid this kind of problem. Assembly & Preparation. Before we get to uploading code and streaming some tunes, there are some a few preparation steps to take care of first. You’ll need to solder something to the shield, and prepare a µSD card. Adding Headers. To get started with the shield, you’ll need to solder on some headers.
If you’re looking to keep the shields stackable, stackable headers might be the best option. Otherwise, straight male headers work as well.
An MP3 Player Shield with stackable headers soldered on. Check out our shield assembly guide for more help in adding headers to your shield. MP3 File and µSD Card Setup. In this phase of the hookup, you may also want to start preparing your µSD card. First, make sure it’s formatted correctly.
The SDFat Arduino library we’ll be using only supports cards formatted for FAT16 or FAT32. Your card is probably already formatted to one of these standards, but it doesn’t hurt to double check.
You may also want to prepare your music files. The VS1053B is capable of playing MP3, AAC, WMA, MIDI, and Ogg Vorbis audio files. The VS1053B supports a variety of samplerates and bitrates for each file type. Check out the datasheet (beginning in section 8 – page 26), to make sure your audio files are supported. MP3’s, for example, are supported at up to a 320 kbps bitrate and a 48 kHz samplerate.
Finally, before loading the audio files onto your SD card, you’ll need to modify their names. The SDFat library only supports “8. 3” file names – that’s eight characters before the ‘. ’ and three characters after (e. “track001. mp3”).
Further, some of the example code we’ll be using later on requires that the audio files be named using special conventions. In the MP3 trigger example the files will need to be named “track001. mp3”, “track002. mp3”, etc. Using the SFEMP3Shield Library.
The SFEMP3Shield Arduino library – written collaboratively by Bill Porter, Michael Flaga, ddz, and Wade Brainerd – is an AMAZING resource for the MP3 Player Shield. Combined with the equally awesome SdFat library.
SFEMP3Shield greatly simplifies the task of interfacing with the VS1053 and using the MP3 Player Shield. We recommend using the SFEMP3Shield library with this shield. On this page we’ll go over how to install and use the library.
On the next page, we’ll make a fun example sketch using it. Install the SFEMP3Shield Library.
To download the latest version of the SFEMP3Shield, click the “Download ZIP” link on the library’s GitHub page. You should also be able to grab it directly from here. This GitHub repo already includes a copy of the SdFat library. so you’re covered there.
The “Sparkfun-MP3-Player-Shield-Arduino-Library-master” folder you extract should have a handful of folders within. The “SFEMP3Shield” and “SdFat” folders in particular need to be installed as Arduino libraries. For help installing the library, check out our Installing an Arduino Library tutorial. You’ll need to place those two folders within your Arduino sketchbook (by default in your home/Arduino folder).
Your file structure should look something like this once installed:. Now restart Arduino (if it was open), and check under the “Sketch” > “Import Library” menu to make sure “SFEMP3Library” and “SdFat” are both listed there.
Upload an Example Sketch. The SFEMP3Shield library includes a few fun example sketches that show off all of its awesome abilities. To begin, try loading up the “FilePlayer” example, by going to “File” > “Examples” > “SFEMP3Shield” > “Examples” > “FilePlayer”. Make sure the MP3 Player Shield is sitting comfortably on top of your Arduino, and upload away. Once uploaded, open up the Serial Monitor and set the baud rate to 115200 bps.
Once the sketch initializes, it should present you with a navigable menu:. Hopefully, towards the bottom of the menu, you’ll see a list of MP3 files that the sketch found on your SD card. Try sending a 3-digit number with padding zeros (e. 001, 003, etc. ) to make one of the listed files start playing. Are you grooving now.
If it’s too quiet, try turning up the volume using the ‘+’ command, or go down with ‘-’. There are all sorts of other fun options to try out too.
Helpful SFEMP3Shield Library Documents. If you’re looking for help using the SFEMP3Shield, begin by checking out the main page of their support site. There’s some good troubleshooting information there. To dig into the code, you can check out their GitHub repository. There’s also a helpful SFEMP3Shield Class Reference guide, which lists all of the functions made available by the library.
On the next page, we’ll make an example sketch using the MP3ShieldLibrary to show off some of its more fundamental functions. Example Sketch: MP3 Trigger. Whether it’s red or purple. everyone loves a good MP3 trigger. Where a simple button or switch is all it takes to trigger a song or sound effect. Let’s use the MP3 Player Shield library to make an MP3 trigger that can rival the big boys. This is a simple example, which shows how to play and stop tracks using the SFEMP3Shield library.
Up to nine tracks can be triggered by the shield, using pins 0, 1, 5, 10, and A0-A4. A5 can be used to stop a currently playing track. Step 1: Set up the SD Card. You’ll need to rename your MP3 files before plugging the µSD card into your shield.
Each of the nine tracks needs to be specifically named from “track001. mp3” to “track009. mp3”. The first trigger – D0 – will play an MP3 named “track001. mp3”, the second trigger – D1 – will play “track002. mp3”, and so on up to A4 which will play “track009.
mp3”. Step 2: Set up the Hardware.
Of course, the shield does most of the hardware set up for you. Aside from sticking the shield on your Arduino, you’ll need to find something to trigger the pins. You could use a switch. of which there are tons of options, or you could just us a simple jumper wire to ground one of the trigger pins.
You can either plug headphones into the on-board jack to listen, or, if you want to get fancy with it, use the three broken out “Speaker” pins. Here’s our setup with a combination of MonoAmp Breakout and 8 Ω Speaker :. Step 3: Load Up the Code. Here’s our MP3 Shield trigger sketch. Copy/paste from below, or download it here :. Check the comments in the code for a step-by-step walkthrough.
This example shows just how easy it is to use the MP3 Player Shield (with a lot of thanks to Bill Porter and Michael Flaga for their library). Call up the MP3player. playTrack() function to start a song, and use MP3player. stopTrack() call to stop it.
Step 4: Trigger Some Tunes. With the sketch loaded up, all you have to do is ground one of the trigger pins (0, 1, 5, 10, A0, A1, A2, A3, A4).
When a new trigger pin is grounded, any currently playing song will stop and the MP3 file it relates to will start playing. If you want to stop a track, briefly connect A5 to ground. You can connect any of these trigger pins up to all kinds of buttons or switches. or just use a strand of wire to momentarily short them to ground. Resources & Going Further.
