volumio lcd display quotation

One of the most awaited plugins for Volumio is finall here: the touchscreen plugin. With it you can easily show the gorgeous Volumio UI on any display, included the official Raspberry PI Display, available on our Shop. Let’s see how to easily achieve a fantastic touchscreen for your favourite music player in less than 10 minutes. This tutorial will explain how to connect the Raspberry PI display and enable the Volumio UI with the plugin.

Assuming you’ve already downloaded and flashed Volumio to your Raspberry PI (we suggest to use the newest  Raspberry PI 3), the first step is the wiring:First, let’s attach the ribbon cable going from the Raspberry PI Display to the PI itself. On the Raspberry PI Side, make sure the blue part of the ribbon cable is facing outwards. Your final goal should look like this:

Notoriously, feeding your PI with an adequate Power Supply is mandatory to have a reliable system. That’s especially true when we connect a power-hungry device like the Raspberry PI Display. Luckily, there’s a way to understand if your PSU is good enough: just power on your pi and observe the screen, if you see a coloured square on the top-right side of the screen, it means that power to your PI is not enough. Don’t you see it? Then all is good.

That’s the easy one. Just connect to Volumio’s WebUi as you would usually do, and navigate to the Plugins page from the settings menu. In Miscellanea category, you’ll find the Touchscreen plugin. Just click install, nothing more. PLEASE NOTE: The touchscreen plugin is compatible with volumio version from 2.001 onwards

The installation will last about 7 minutes, so wait patiently until you see “Installation Complete”. Now you can enable or disable the Display output to your likings.

I must admit that altough this display is not particularly brilliant when it comes to resolution and colour accuracy, it looks indeed very nice with Volumio’s UI. Also, usability is very good on the Raspberry PI 3 and the UI runs smoothly also with big libraries… So, folks, enjoy!

If you don’t have a Raspberry PI, or you’re simply looking for alternatives to the Official Raspberry PI Display, there are at least two extra options for you:

The Odroid display is not only a viable alternative, it also have several advantages over its PI counterpart:Since it takes power from USB and video signal from HDMI, it can be used virtually with any Computer with an HDMI output, not just the Odroid or the Raspberry PI.

UPDATE: Lot of time since I published the original article. The Odroid 7” does not seem to work properly with Raspberry PI (not tested with the Odroid). So, if you’re looking for a display for the Raspberry PI, get the official one.

The Waveshare 7” display has become rapidly a widely adopted display, thanks to its cheap price. However this particular touchscreen has shown several reliability issues (altough this seems fixed in latest models, thanks to a firmware update), it requires a particular touchscreen driver which is not always included in major distros and its colour reproduction is not the best.

Here we are folks! Hope you found this article helpful, you can share via comment below how you use your Volumio’s touchscreen setup and if there are other display alternatives!

This article was written in 2014, and since then newer and better i2s DACs have emerged. Luckily, we now have a selection of the best among them right here on Volumio shop. So, to save you the fuss of research and comparation, you’ll find listed below my personal choice of the best 4 I2S DACs for Raspberry PI.

You know, Raspberry PI can be hooked up to a wide variety of Accessories. I really do like to have a little Display attached to it, to show current title playback (coming soon on Volumio!) and so on. This clever raspberry pi i2s DAC has it capabilities, since it offers a GPIO connector, to easily hook a display on it. Not to mention that this little board offers the same advantages of raspberry pi i2s connected DACS. RaspyPlay3 is developed by a serbian community of DIY and audio lovers, just browse their website to find out they really interesting articles (use google translate and be prepared for some lost in translations…). This raspberry pi i2s dac can be customized with your preferred Capacitors, meaning you can really tailor it to your personal tastes. Plus, you can find all the documentation you need to find out how to build this raspberry i2s cad on your own. Thanks Nebojsa!

Now you should have a comprehensive idea of why raspberry pi i2s dac is the way to follow if you want to achieve pretty good sonics performances, while  slightly emptying your pockets. I am really reccomending to use this solution if you want a really valuable Audiophile Music Player withouth spending too much, furthermore Volumio + PI + raspberry pi i2s DAC is a solution you can tailor to your very own needs. And as Volumio development will progress, you’ll have also more functionalities available.

The above command responds with; dev/fb0 /dev/fb1- which as far as I understand means it is seeing both the HDMI output (fb0) and the LCD screen (fb1).

From here on I am stuck - I cannot get any display on the LCD screen. The web UI displays reliably on the HDMI output but nothing I have tried can make it switch to the LCD screen.

Rather than plug your Raspberry Pi into a TV, or connect via SSH (or remote desktop connections via VNC or RDP), you might have opted to purchase a Raspberry Pi touchscreen display.

Straightforward to set up, the touchscreen display has so many possibilities. But if you"ve left yours gathering dust in a drawer, there"s no way you"re going to experience the full benefits of such a useful piece of kit.

The alternative is to get it out of the drawer, hook your touchscreen display to your Raspberry Pi, and reformat the microSD card. It"s time to work on a new project -- one of these ideas should pique your interest.

Let"s start with perhaps the most obvious option. The official Raspberry Pi touchscreen display is seven inches diagonal, making it an ideal size for a photo frame. For the best results, you"ll need a wireless connection (Ethernet cables look unsightly on a mantelpiece) as well as a Raspberry Pi-compatible battery pack.

In the example above, Belkin WeMo switches and a Nest thermostat are manipulated via the Raspberry Pi, touchscreen display, and the InControlHA system with Wemo and Nest plugins. ST:TNG magic comes from an implementation of the Library Computer Access and Retrieval System (LCARS) seen in 1980s/1990s Star Trek. Coder Toby Kurien has developed an LCARS user interface for the Pi that has uses beyond home automation.

Building a carputer has long been the holy grail of technology DIYers, and the Raspberry Pi makes it far more achievable than ever before. But for the carputer to really take shape, it needs a display -- and what better than a touchscreen interface?

Now here is a unique use for the Pi and its touchscreen display. A compact, bench-based tool for controlling hardware on your bench (or kitchen or desk), this is a build with several purposes. It"s designed to help you get your home automation projects off the ground, but also includes support for a webcam to help you record your progress.

The idea here is simple. With just a Raspberry Pi, a webcam, and a touchscreen display -- plus a thermal printer -- you can build a versatile photo booth!

Various projects of this kind have sprung up. While the versions displayed above uses a thermal printer outputting a low-res image, you might prefer to employ a standard color photo printer. The wait will be longer, but the results better!

How about a smart mirror for your Raspberry Pi touchscreen display project? This is basically a mirror that not only shows your reflection, but also useful information. For instance, latest news and weather updates.

Naturally, a larger display would deliver the best results, but if you"re looking to get started with a smart mirror project, or develop your own from scratch, a Raspberry Pi combined with a touchscreen display is an excellent place to start.

Want to pump some banging "toons" out of your Raspberry Pi? We"ve looked at some internet radio projects in the past, but adding in a touchscreen display changes things considerably. For a start, it"s a lot easier to find the station you want to listen to!

This example uses a much smaller Adafruit touchscreen display for the Raspberry Pi. You can get suitable results from any compatible touchscreen, however.

We were impressed by this project over at Hackster.io, but note that there are many alternatives. Often these rely on compact LCD displays rather than the touchscreen solution.

Many home automation systems have been developed for, or ported to, the Raspberry Pi -- enough for their own list. Not all of these feature a touchscreen display, however.

Another great build, and the one we"re finishing on, is a Raspberry Pi-powered tablet computer. The idea is simple: place the Pi, the touchscreen display, and a rechargeable battery pack into a suitable case (more than likely 3D printed). You might opt to change the operating system; Raspbian Jessie with PIXEL (nor the previous desktop) isn"t really suitable as a touch-friendly interface. Happily, there are versions of Android available for the Raspberry Pi.

The Raspberry Pi 3 is very overpowered for the demands of volumio. By lowering the speed (underclocking) the system, and minimising the activity of unused parts like the GPU, we can reduce power consumption and perhaps even noise / jitter on the outputs.

Computer monitors are great for office work, gaming, and browsing, but these displays can be large and power consuming. One display found in both the commercial and hobby world is the HD44780 16 x 2 display, which can display two lines of alphanumeric characters. In this tutorial, we will learn how to connect one to a Raspberry Pi and code it using the Python programming language!

The HD44780 has a number of registers and commands that are used to control the display, but getting the display to work can be somewhat tricky, especially for inexperienced users. This is why most coders will turn to libraries. They include prewritten code that has been proven to work. In this tutorial, we will be relying on two libraries to control the LCD: RPLCD and RPi.GPIO. Before we can continue, we need to install the RPLCD library by using the following command in a terminal window:

First, we need to import the RPi.GPIO library as GPIO. This will allow us to use the GPIO library and refer to it as “GPIO”, which is easier than RPi.GPIO. The next library that we need to include is the RPLCD library, which allows us to use the LCD. Therefore, the first two lines of code in our Python program will be:

CharLCD is a Python library that lets users access Adafruit character LCDs from a Raspberry Pi. Next, we need to tell the RPLCD library what pins we have connected the LCD to. In the Scheme-It schematic above, we connected the LCD pins to the following GPIO (using the BOARD numbering scheme). The Pi has two numbering schemes; BOARD and BCM. The BOARD numbering scheme refers to the I/O header whereas the BCM scheme refers to the GPIO numbers from the Broadcom IC. It is often easier to use BOARD scheme as you can count the pins to determine which one you need to use whereas the BCM scheme requires you to first choose a GPIO and then determine its pin number (BOARD).

Now that we have configured the LCD, it’s time to do a few tasks with it! The first function that we should learn to use is “write_string()”, which is used to write text to the LCD. Try the following command:

Writing predefined strings is not entirely helpful, and displaying variables can be very beneficial. Luckily for us, Python allows typecasting, where one variable can be converted into another variable. The example below shows how we can display a counter, which displays an integer on the LCD, along with a simple “Count” message.

Next, we’ll learn how to clear the display. Displays like those based around the HD44780 are static, and they remember what you tell them to display. However, this also means that when you want to write new data, you may need to clear the entire display. Therefore, you can use this clear function to clear the display:

Sometimes printing text on the top left of the display may not be desirable. In this case, you will need to change the cursor’s position. To do this, we can set the cursor_pos variable to a specific value. The example below sets the cursor position to row 2 (x) and column 0 (y).

At the end of your program, you should include the function “lcd.close()”, as this will free up the GPIO for other programs that may need to use them.

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!

The project I"m currently working on involves a Raspberry Pi 4 running Raspberry Pi OS 32-bit and an LCD panel with rather odd dimensions - 1920x480. It"s an 8.8" ultrawide panel https://www.aliexpress.com/item/4000133 ... 4c4dMnq7ke. It connects via HDMI. I"m running a minimal X install with no desktop environment, just a Chromium kiosk session. The Pi is connected to the LCD panel board using a micro-HDMI to HDMI adapter.

Since it"s such an odd set of dimensions, the Pi doesn"t show anything on the display until X starts. I"m guessing it just can"t find a set of values that are close enough to enable the display.

Lots of folks are using this MIPI adapter atm .. Nearly all of them are having issues which is (most likely) down to some incorrect EDID (I quote "works on windows, no display on Rpi; image position incorrect, ...)

I have been running Allo Digione (not the signature) with RPI3 and a Coax DAC for last 3 years almost flawlessly and prior to that for 4 years I ran RPI directly with a USB DAC. During this time I tried Rune and Moode before eventually settling on Volumio and my observation is that when we upgrade the OS version, something or the other eventually breaks in light of getting newer features and then we have to look for the fix to come. So a custom programming may not always give peace of mind while upgrades and best advised to Run the setup headless (the way it was originally intended and making it align to KISS) and control via mobile browser through the Web UI.

I use TIDAL through the paid plugins on Volumio apart from Spotify and Youtube plugins and also having lossless audio on Local Home NAS. A custom digital display will fall short of displaying album arts and you would miss the complete experience of browsing albums. Library searching will also be cumbersome when lot of results are returned and unless you get up and turn knobs every now and then or implement a USB remote this may not serve you well.

If you need a complete streamer with its own display, spend additional bucks and get a dedicated streamer of the likes of CA CXN or the Bluesound Node 2i. You will even benefit from a better power supply.
