With the arrival of the new official Raspberry Pi Touchscreen, we were excited to find applications for it in our Max2Play system. Since audio applications have been one of our main focuses from the start, we immediately thought of a combination of sound card and screen. We had already created great bundles for both touchscreen and sound card solutions, but the combination was something we were still working on. The main connectors of the Raspberry Pi can only be used for one device at a time. So we had to become creative and can now show you the result.
With just a few tweaks to the standard Raspberry Pi Touchscreen and Case, we can now combine it with a powerful DAC sound card directly on-board. When we incorporate these components into our Max2Play Image using the elegant Jivelite visualization and our own RPi display plugin, we get a great setup with all the features we know and love, great sound and massive touchscreen to control it all.

We offer a bundle including all necessary components for this instructable in our shop.

Step 1: Connect the Touchscreen and the Sound Card with the Raspberry Pi

Just follow the instructions from your touchscreen and make sure everything is well adjusted using spacers and screws. Then put the sound card on top of the Raspberry using the GPIO connector bar. We are using a HiFiBerry DAC+ light for our system. Its affordable yet powerful nature combined with its small size makes it perfect for this project.

You can buy the HiFiBerry DAC+ light and other HiFiBerry sound cards that work with this setup like the Digi+ or the DAC+ in our shop

<p>Hi, in Step 1 it looks like the touchscreen gets its power through the two cables that are connected to the raspberry pins (power to microusb in the pi?).</p><p>In Step 4 it looks like those same cables are now not any more connected to the raspberry, but to the soundcard and the touchscreen. Or did I get this wrong?</p><p>Where would the microusb-powercable go? I have all parts to start the project, but want to make sure, I'm getting this right, before I start.</p><p>Thanks, Fred</p>
Hi Fred,<br>The image in the first step is does not have the sound card yet. The touchscreen gets its power from the Pi through the white monitor connector. The pin connectors' cables have to be connected to the sound card as detailed. The two connectors on the monitor's connector ridge where it says GPIO have the inscription GRD for ground and 5V for the 5 Volt.<br>You can also now set up the software much easier and quicker with our dedicated 7&quot; Touchscreen Image for exactly this application. It automatically configures the Plugins &quot;RPi Display&quot; and the Jivelite Installer. You can find the download on our website at http://www.max2play.com/en/max2play-image/<br><br>If you are still having questions, feel free to join our forums or write another comment here.
<p>I have one more question: you mentioned in earlier comments, that there is the option of a screensaver in jivelight. I couldn't find the option in the web application. (I used the image you recommended with preinstalled jivelight). I updated max2play and got logitech media server and jivelight working, but found no option to toggle the screensaver.</p>
<p>Hi Fred,</p><p>The option should be in the Jivelite interface itself under Settings &gt; Screen &gt; Screensaver. Make sure that you installed the skin for your 7 inch display.</p>
Hi, <br>thanks for the fast answer. Tried your image out (without the hifiberry attached) with the max2play license that came with the card... really easy to setup, everything works, especially jivelight...perfect!<br>Will try to solder the power connection tomorrow... will be the first time for me, hope I get this right :)
<p>Hi, I was wondering if it is possible to use the 7inch display with the hifiberry amp+?</p><p>Thanks,</p>
<p>Hi Jamie,<br>The newest model of the Amp+ now has a connector bar on top. With this model, you can thusly follows the same steps as with this Instructable for the DAC+ and should be able to get it to work. We are also currently working on a full Amp-Solution with a fitting case.<br>However, the old Amp+-models do not work with this setup.</p>
Hi, I've got the set from you with touchscreen, hifi berry amp and pi2. When connecting the supplied psu with the amp and powering the touchscreen with pin 1+6 from the amp the pi +screen is working, but not the amp. The system only works when connecting an additional 5v micro usb to the screen. Is that supposed to be like that? Regards Martin
<p>After struggling with some gotchas i finally made it using the max2play kit. Lessons learnt:</p><p><strong>Which </strong><strong>power pin?</strong></p><p>Maximilian from max2play clarified the &quot;which power pin confusion&quot; (see the other posts): </p><blockquote>&quot;Using gpio14 instead of GND works too and should not do any harm, but correct is using GND.&quot;</blockquote><p><strong>Not every SD image has display support</strong><br>initially the display did not work, but with his friendly support we found out that a wrong image was packed<br></p><p><strong>Screws can change</strong></p><p>The screws that fix the case against the display were too small, but some standard HD screws from the grabble box did the job</p><p><strong>USB cutout too small</strong></p><p>My USB HD plug would not fit, so i had to remove the plank between the sockets.</p><p><strong>Display controller cutout too small</strong></p><p>The cut-out in the case was not big enough for the display controller, which resulted in a force that lifted the display off its base plate. A distance plate was provided with the kit but this was not thick enough.<br>This was a hard one...<br>In the end i managed to cut some cardboard to the same shape as the distance plate, effectively making it 1mm higher. See image.<br><br>Happy hacking!<br></p>
<p>Hi AxelR9,</p><p>thank you for sharing your experience and inspirations. Our enclosures are supposed to be assembled by the customer, which sometimes includes small adjustments to the bodywork, e.g., modification on the cutouts if you intend to use thicker than usual USB-cables. Anyway, we appreciate your support very much indeed. I can tell you, that we are currently developing a new display enclosure, which will address some of the issues. Stay tuned!</p>
<p>One more question: I don't want to connect power to the wrong pin. In the pictures you connected the first and the fourth with cables, but i thought the third is Ground and Nr. 4 is some GPIO pin? Or are both possible? Thanks for your answers</p>
<p>Hi Fred,<br>This image shows you exactly where the cables should be connected. Click on it to get a fullscreen image.</p>
<p>is that right that 4th pin on the picture is GPIO14 </p><p>(according to this scheme <a href="http://www.element14.com/community/docs/DOC-73950/l/raspberry-pi-2-model-b-gpio-40-pin-block-pinout" rel="nofollow"> http://www.element14.com/community/docs/DOC-73950...</a> )</p><p>which is then connected to GROUND to Touch screen card ?</p><p>Thank you</p><p>Tomas</p>
<p>Hi Tomas,</p><p>Yes the order shown in the pictures above is the correct arrangement for the pins for this setup.</p>
<p>Thank you very much!</p>
<p>Hi, sorry this may be a stupid question, but I was wondering if I can connect this to my Gainclone amp, and speakers. Or is this an amplifier itself?<br>Can i use my spotify account on this box? I am really thinking of ordering your kit including HiFiBerry DAC+ Pro. Keep up the great work!</p>
<p>Hi chellebust,</p><p>This system uses a DAC (Digital-Analog-Converter), so the audio signal it puts out is an analog stereo signal that you should be able to connect to your Amp via the RCA connectors.<br>Spotify can be used through the Squeezebox Server, there is a third party plugin called Triode that enables Spotify-Support.</p>
<p>We are happy to announce an update on this Instructable's functionality:<br>The Jivelite installer now includes a screensaver option similar to that of the old Squeezebox Touch with a display of time and date both in digital and analog form. This screensaver is specifically for the 7 inch display and is not recommended for the 2,8 inch display since its technology makes it prone to screen burning. Here are few pictures of the screensaver:</p>
<p>To day I got the HiFiBerry DAC+ RCA and installed it with my 7 inch touchscreen. It mounts to it. I had to cut the power cables that do power to the touchscreen and I solder them on the power pins of the HiFiBerry. Installed the Max2play on it. Seems like it is not like a Squeezebox touch any more but just play music on what you put on the boot SD card and can play other Squeezebox on the LAN. I have not found out how if can use it like a Squeezebox touch with the HiFiBerry but for sure the HiFiBerry make it play music that sounds better then the built in head phone jack of the Pi. </p>
<p>I all ready got this set up and it's working real good. But it's hard to find a 7 inch case for this touch screen and Raspberry PI. Any link were can buy one?</p><p>The screen has 4 other mounts on the out side corners looks like for a case that can mount on it.</p>
<p>Hi Raymond,<br>Thanks for enjoying our software, we appreciate the support. We sell the case for the 7 inch touchscreen in our store both separately and in a bundle, here is the link to the individual item: <a href="http://shop.max2play.com/en/zubehor/case-gehaeuse/raspi-case-83.html" rel="nofollow">http://shop.max2play.com/en/zubehor/case-gehaeuse/...</a></p><p>This is the official case for the screen with screws that fit those four mounts.</p>
<p>Looked before and I could not find that link to the case hard to find I guess.</p><p>Looks nice. I will buy it later when I have the $ thank for the link to it.</p>
