Pyqt5 raspberry pi

After looking around for a while, trying to find some easier way to realize what I had in mind, I came across this tutorial.

Since I had basically all the functionality already implemented in Python on my Raspberry Pi, I thought it would be a good idea to use Python diy camera lens repair Qt for this.

So I downloaded and installed Anaconda.

But soon I noticed, what I already was suspecting of being a potential problem, actually showed up as a real problem. The GUI did not react during this time. I came detonator dayz another example that shows you how to use threads to avoid exactly this particular problem.

On my Raspberry Pi, I also upload the currently measured values for temperature, humidity and pressure to Weather Underground. If you want to build an executable and therefore being able to run it on a computer that has not installed Anaconda, you can additionally use PyInstaller to pack all the necessary runtime libraries together in one executable file.

In the end, I used Resource Hacker to change the icon of the generated executable, so that it is the same one like I use within the GUI. Like you can see, the final executable is rather large, since the whole runtime environment for Python and Qt is included. Like Like. You are commenting using your WordPress.

The little programs I wrote were games, in particular games to simulate landing on the moon Apollo was important, and still flying, back then. That version of Python comes standard with the latest version of Raspbian, version 9. So I had a pretty good idea what Qt was capable of, especially the changes wraught by Qt4. I tried to pull down the sources and build a local copy of Qt5 for myself, but since a single compile cycle for all of Qt takes multiple days building natively on the Pi, after going through two such back-to-back cycles trying to debug what the build failed on, I then turned to the Raspian repo versions of Python and PyQt5 and got on with my life.

With Raspbian you have everything you need either installed directly or easily available via the repos. Once those packages were installed I started to look around for some tutorials to help me get oriented with PyQt5.

I found a site with lots of examples, and started to code my way up the learning curve. You can see some of those very primitive examples on the screen shot above. Of interest was a link on the site to download all the source.

I figured I could rifle through the code for the interesting bits and build on that, but when I clicked on the link I was invited to buy the course in order to get the source code. No thanks, so I went back and continued to copy-and-code. I may or may not put up my own set of tutorials that are clean, correct, and interesting. If you have a Raspberry Pi and install PyQt5, then you should play with this and see what happens when you move tabs around or delete any of them, especially those with widgets.

The tabs with widgets will clean up after themselves in my version. Search for: Close. Raspbian Desktop with running PyQt5 demo applications My work on the Raspberry Pi is a hobby of sorts, in which I bring to bear nearly 50 years of writing software in some language on some computer. Setting tabs as closable displays a close button on each tab.

Trust me when I say that my version works as advertised. The signal-and-slot callbacks to execute when a tab was selected were never connected, and when I finally connected them, then they never worked. I added the correct callbacks in lines 44 and On lines 26 and 27 of my version, setTabsClosable and and setMovable, were both set to True. This turned on the close buttons and made the tabs more interesting by allowing them to be moved around.

Layouts were improperly set up.Please note the user and login for the Linux image. To build on the Raspberry Pi we need a cross-compile toolchain. The toolchain will contain compilers, linkers and other tools that run on the host workstation but create executables for the target Raspberry Pi.

For embedded development, one normally uses a vendor-supplied toolchain, but in the case of the Raspberry Pi, there is no official vendor supplied toolchain. This is a Linaro based toolchain for the ARMv6 platform with hard floating-point support. Alternatively, we could have built our own toolchain.

Our first step is to get and install a cross compiling toolchain. Since this toolchain is built for bit systems, you will need a set of bit libraries installed if you are on a bit system. On Ubuntu systems, this can be accomplished by installing the ialibs package. Unfortunately, this is a deprecated transitional package, with no replacement. As a convenience, you can create a setdevenv.

We do this by burning a Raspbian image to an SD Card. Repeat: Make sure you know the correct device to use with the subsequent dd command, or you could lose all your data. Additional packages will be needed on the Raspberry Pi in order to build Qt 5 and run Qt 5 applications.

Here is a list of the basic packages needed for building and running Qt 5. These are Ubuntu package names, but there should be similar packages on all Linux distros. Building software on the Raspberry Pi will be too slow, thus we will need to return to our workstation and use our cross-compile toolchain to perform the remainder of the work.

A traditional method of cross-platform development is to create a chroot or jail environment to build against. However, since we have a working image of the Raspberry Pi, we can use that instead and it will be much easier. Building Qt 5 will now proceed normally in much the same way as building Qt 5 for the desktop.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

I'm attempting to convert a python file into an executable file using PyInstaller. Within the python file, the following imports are added:. Whenever I try to execute the binary executable in the terminal, I either get no module 'PyQt5' found or no 'QtCore' found.

Gui', 'PyQt5. Core', 'PyQt5. Widgets'] with no luck. Currently, I'm suspecting the hook files are not looking in the right place.

Currently, I'm out of idea on how to go about this. I'm thinking of writing my own hook files, but I'm having trouble with that too. Learn more. Asked 3 days ago. Active 3 days ago. Viewed 20 times.

I have a Raspberry Pi 3 with Raspbian installed, along with a 7" touch screen. I'm in the process of creating an application in Python to read several DS18B20 Thermocouples to monitor the temperature of several aquariums relays attached to heaters will be added later.

Just put the tar files someplace that you can get to them easily. You'll need to extract each of them, using the tar command, with the -xzvf tag so you'll end up with tar -xzvf sip In each folder, you'll need to set up for the build. This is done by typing "python config. The contents of each directory needs to be built and installed, go to your sip folder and type "make" this will take a very long time. After it's through, type "sudo make install". I developed a similar application using PyQt4 and Qt4-designer.

You have to install pyqt4 all modules:. I can't leave a comment, not enough reputation, but thought I should mention this in case it helps anyone using VirtualEnv:.

In my case Raspbian on a Raspberry Pi 3, Python 3 in a virtual environment the answer provided by CharlieHorse is the only one which worked as I could not get. I tried something like this question on Stack Overflow but because PyQt5 relies on SIP which interfaces with some C code, it needs to be compiled from scratch and can't just be copied, as recommended in the accepted answer of that question.

Getting Started with PyQt5 on Raspberry Pi

So does anybody know how to use or install PyQt5 for the subsequently installed python3. I think I am on the right way, but I do not understand what qmake is or what it means. I installed sudo apt-get install qt5-default Then I did the same procedure as already mentioned. Now I get the error fatal error: sip. Thanks guys. EGuy EGuy 63 1 1 silver badge 8 8 bronze badges. Have you considered building from source? I am trying it but it has not worked yet. Check out the edits.

While in Part3 of the Raspberry Pi industrial Automation system, I will design a complete HMI application for the Raspberry Pi, which will be able to monitor different sensors and control different electrical loads. Subscribe right now so that you never miss any of my upcoming tutorials.

The components and tools used in this project can be purchased from Amazon, the components Purchase links are given below:. I may make a commission if you buy the components through these links. I would appreciate your support in this way!

This is a 7 channel relay module, currently, I am using only 4 relays which are connected with the Raspberry Pi GPIO pins 26, 19, 13, and This relay module is powered up using a 12v Adaptor.

After you are done with all the settings, the next step is to install the PYQT5 software which is really simple. This is a good designing and programming practice to keep all your project files in one place.

I started off by creating a folder for my project files. While you are on the Raspberry Pi desktop, right-click and select Create New and then click on the folder. I will save all my project files in this folder. The Qt 5 designer software is provided with all the components and tools which can be used to design advanced level Raspberry PI HMI systems.

The Qt 5 designer software is very user-friendly; drag and drop the component you want to use. In my case, I am going to use a Pushbutton. Now, select a label, drag and drop it on the form.

Raspberry Pi 4

Select a horizontal line from the left side components Widget Box, and drop it on the form, change the width of the line as per your requirement. This line is optional and is only used for designing purposes to make the application looks attractive. Select a Push Button Drag and drop it on the form. Change the dimensions of the Push Button as per your requirement. On the right side, you can see the Property Editor, you can change the width and height values, the X and Y axis values, then scroll down and set the font size, again scroll down until you see the text, click and delete the text PushButton.

After adding all the four buttons change the objectName of all the buttons. Now we will start the Raspberry Pi Industrial Automation programming. After you click on the Thonny Python IDE, this will open the editor where you can write your program. Simply copy and paste the following program into the editor. The Qt Widgets Module provides a set of UI elements to build user interfaces in the classic desktop style. Inside RPi.

The advantage of using this numbering system is that irrespective of the RPi board revision, your hardware will always work. BCM numbers are the second numbering system. This is a way of working at a lower level.
