using lcd touch screen with raspberry pi free sample

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.

Several options are available to create a Raspberry Pi photo frame, mostly using Python code. You might opt to script your own, pulling images from a pre-populated directory. Alternatively, take a look at our guide to making your own photo frame with beautiful images and inspiring quotes. It pulls content from two Reddit channels -- images from /r/EarthPorn and quotes from /r/ShowerThoughts -- and mixes them together.

Rather than wait for the 24th century, why not bring the slick user interface found in Star Trek: The Next Generation to your Raspberry Pi today? While you won"t be able to drive a dilithium crystal powered warp drive with it, you can certainly control your smart home.

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?

Setting up a Raspberry Pi carputer also requires a user interface, suitable power supply, as well as working connections to any additional hardware you employ. (This might include a mobile dongle and GPS for satnav, for instance.)

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!

Projects along these lines can also benefit from better use of the touchscreen. Perhaps you could improve on this, and introduce some interesting photo effects that can be tweaked via the touchscreen prior to printing?

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.

Many existing projects are underway, and we took the time to compile six of them into a single list for your perusal. Use this as inspiration, a starting point, or just use someone else"s code to build your own information-serving smart mirror.

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.

Alternatively, you might prefer the option to integrate your Raspberry Pi with your home audio setup. The build outlined below uses RuneAudio, a Bluetooth speaker, and your preferred audio HAT or shield.

Requiring the ProtoCentral HealthyPi HAT (a HAT is an expansion board for the Raspberry Pi) and the Windows-only Atmel software, this project results in a portable device to measure yours (or a patient"s) health.

With probes and electrodes attached, you"ll be able to observe and record thanks to visualization software on the Pi. Whether this is a system that can be adopted by the medical profession remains to be seen. We suspect it could turn out to be very useful in developing nations, or in the heart of infectious outbreaks.

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.

One that does is the Makezine project below, that hooks up a Raspberry Pi running OpenHAB, an open source home automation system that can interface with hundreds of smart home products. Our own guide shows how you can use it to control some smart lighting. OpenHAB comes with several user interfaces. However, if they"re not your cup of tea, an LCARS UI theme is available.

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.

Note: This is user manual for version V1.0 7″ DSI screen. When you receive the version V3.x 7″ DSI screen, please visit link: https://osoyoo.com/2023/01/06/7-dsi-touch-screen-v3-for-raspberry-pi/

This LCD display supports Raspbian, Ubuntu MATE, Snappy Ubuntu Core, OSMC, and Windows 10 IOT Core and so on. Please download your system image from raspberry Pi official website: https://www.raspberrypi.org/downloads/

The 7″ LCD display is an LCD display which connects to the Raspberry Pi through the DSI connector. It is capacitive touch LCD. It doesn’t need install driver, and you can plug and play. The Physical resolution of LCD display is 800*480.

Thirdly, Insert the SD card into the card reader, and connect with computer, and select the image system and the device, and then click “write”, as below:

The touch screen can be used as a mouse device. When we need to input text data to Raspberry Pi board, normally we have to connect a USB keyboard to Pi and this is really inconvenient.

LCD displays have an optimum viewing angle, and depending on how the screen is mounted it may be necessary to change the orientation of the display to give the best results. By default, the Raspberry Pi display and Raspberry Pi are set up to work best when viewed from slightly above, for example on a desktop. If viewing from below, you can physically rotate the display, and then tell the system software to compensate by running the screen upside down.

Note: If failing to adjust the brightness, please check the line “disable_touchscreen=1 ” in /boot/config.txt and comment it out  “#disable_touchscreen=1 #”

and connect the other end of the USB cable to the USB port of the LCD; then supply power to Raspberry Pi; after that if the display and touch both are OK,

A detected touchscreen will also cause the fbheight and fbwidth parameters in /proc/cmdline to equal 480 and 800 respectively (the resolution of the screen). You can verify this by running:

Depending on your display stand, you might find that the LCD display defaults to being upside-down. You can fix this by rotating it with /boot/config.txt.

If some windows in X are cut off at the side/bottom of the screen, this is unfortunately a side-effect of developers assuming a minimum screen resolution of 1024x768 pixels.

At the moment you can’t use HDMI and the LCD together in the X desktop, but you can send the output of certain applications to one screen or the other.

You may need to increase the amount of memory allocated to the GPU to 128MB if the videos are 1080P. Adjust the gpu_mem value in config.txt for this. The Raspberry Pi headline figures are 1080P30 decode, so if you are using two 1080P clips it may not play correctly depending on the complexity of the videos.

Raspberry Pi OS provides touchscreen drivers with support for ten-finger touch and an on-screen keyboard, giving you full functionality without the need to connect a keyboard or mouse.

The 800 x 480 display connects to Raspberry Pi via an adapter board that handles power and signal conversion. Only two connections to your Raspberry Pi are required: power from the GPIO port, and a ribbon cable that connects to the DSI port on all Raspberry Pi computers except for the Raspberry Pi Zero line.

systemd is the preferred method of starting applications on startup, but it is also one of the most complicated to use. With systemd, you have the benefit of being able to tell Linux to start certain programs only after certain services have started. As a result, it is a very robust tool for initializing your scripts and applications.

systemd is a relatively new suite of tools in the Linux world, and one of its intended purposes is to manage system processes after booting. When it was first released, systemd was meant to replace the init.d tool for starting programs. As of 2015, most of the major distributions include systemd, and since many kept init.d around for legacy support, you have the option of using either one. Be aware, however, that init.d may be deprecated, so systemd seems to be the future (for now).

If your program does not require a GUI (such as our blink.py example), then you can use the following template to create a systemd service. If you do need a GUI (e.g. you require the X Windows System to have started), see the next section. Creating a unit file without requiring a GUI means you can also run your program on boot in a headless environment.

Feel free to change the Description as desired. The After key denotes when our program should run. multi-user.target is the system state where control is given over to the user (a "multi-user shell") but before the X Windows System is started. That means our program will run even without logging in! You can change this, depending on which services you need active before running your program (for example, network.target if you need networking). See here for a listing of all targets.

ExecStart is the command (or set of commands) used to start our program. Notice that we are using absolute paths to the version of Python we want as well as the location of our program.

WantedBy in the [Install] section specifies the target we want our service to be included with. In this example, we want our service to run when the multi-user.target unit is run (or, more specifically, just after it, based on the After parameter).

Under [Service], we specify some environment variables. We want to connect to our primary display (this assumes only one display is connected to our Pi), so we set DISPLAY to :0, and we tell our application where to find the necessary credentials to use the X windows system with XAUTHORITY. ExecStart is the command we want to run (starting our Python clock program, in this case).

Unfortunately with systemd, we cannot tell exactly when the X system will start, and we cannot necessarily guarantee that a user will be logged in (unless you have enabled auto-login with sudo raspi-config). To account for this, we will brute force our program to restart (with Restart) every 10 seconds (with RestartSec) if it fails or exits. KillMode tells systemd to kill off any processes associated with our program if the service fails (or exits), and TimeoutSec=infinity means that we don"t ever want to stop trying to execute our program.

Reboot with sudo reboot to verify that your program works. You should see your Python clock program running after you have logged into your graphical desktop.

If journalctl is not living up to your expectations, you can try logging output to a file. To do that, change the ExecStart call to the following (using clock.py as an example):

This starts a new bash shell, runs your program, and redirects the output (stdout) to a new clock.log text file. The 2>&1 command says that any errors (stderr) should also be redirected (written to) the same log file. Any output (e.g. from Python print() commands) or errors will then be saved to clock.log. You can view the log with the following command (note that you might need to stop the service and program before viewing the log):

For some services, like our clock.service example, you will need to stop the service before stopping the program. That"s because even if you stop the program (e.g. our Python GUI clock), the service will simply restart it 10 seconds later! To stop a service, enter the following command:

Note that stopping the service should send a stop command (SIGTERM--terminate signal) to your program. In most cases, this should stop the service and your program. If your program does not stop, see below on stopping your program.

This can be helpful to restart a service if you"ve made changes to it without having to reboot the system. Just remember to run sudo systemctl daemon-reload if you do make any changes to a .service file!

ps -ax tells Linux to list out all the currently processes. We send that output to grep, which allows us to search for the keyword "python" (feel free to change it to the name of your program). Find the process ID (PID) number to the left of the listed process, and use the kill command to terminate that process:

Note that you do not need to delete the .service file, as disabling it will prevent it from running on startup. However, if you would like to delete the file, you can using the following commands (once again, replacing clock.service with your service filename):

Some users want to connect more than one display to their PC. Here we talk about how to setting the touch to make the touchscreen to control its screen separately.Connect touchscreen to PC. Here we use an standard PC monitor and connect an 7inch HDMI LCD (C) for example. We make the monitor as main screen and the touchscreen as secondary screen.

If we want the touch of the touchscreen to control the desktop of the touchscreen itself. Just press Enter key to pass the first screen. And the second screen, when you find that the black text is displayed on the touchscreen, just touch the center of the touchscreen to finish this setting.After this setting, the touch on the screen will just control this touchscreen even thought it is not the main screen.

1 If the first screen and the second screen are touchscreen as well, you can touch them when the text is displayed on the screens. Then you can find that all the touchscreen can work.

When working with Raspberry Pi, you should set the resolution of the LCD by yourself, or else the LCD screen will not work. For more detailed information, please read the following section.

Download the Raspbian image from Raspberry Pi web site. Write the image to a TF card and append the following lines to the config.txt file which is located in the root of your TF card:max_usb_current=1

For Pi Zero / Zero W: if you"ve used an SD card on a Pi 3 and then attached the card to the Pi Zero, the touch screen often doesn"t work. In such cases, you have to write a fresh system image to the SD card. The first boot up must be done on the Pi Zero but not Pi 3, due to initialization for a corresponding device.
