Re: No sound from Java application

Update: Tried different versions of Raspbian/Raspberry pi os including the new 64 bit version, in combination with different version of OpenJDK ranging from Java8 to Java13. No success This weekend I tried the Ubuntu Server for ARM64 instead, installed it together with the Ubuntu minimal desktop. In...

No sound from Java application

Hi, programming in OpenJDK 11.0.2 for Raspbian 10. Found a library at Github that plays mp3-files, works great at Windows where I do the coding. But when running it at my pi 4B no sound can be heard. Sound is working for other apps at the pi, like Youtube and playing the same mp3 with VLC. Something...

Re: Touch ignored by my 7" touch screen/JavaFX-app at pi 4

Update: I found some documentation about how to configure JavaFx for the screen in particular using a Component called Monocle. After having added the monocle dependency to my Maven-project as follows: <dependency> <groupId>org.testfx</groupId> <artifactId>openjfx-monocle</artifactId> <version>jdk-1...

Touch ignored by my 7" touch screen/JavaFX-app at pi 4

Using a pi 4 with the "official 7 inch touchscreen" and a JavaFX application I am developing. Working fine with mouse but no response when tapping/touching the touch screen. My application, built with IntelliJ/Maven and using Java 11 SDK with OpenJFX 11.0.2 is showing a simple form for inp...

Re: Java IDE for Pi 4 - need to create simple GUI

Thanks clicky, I will check it out. When reading around the net and trying to figure out what prerequisities there are for creating a GUI using Java at the pi 4 I reckon that since OpenJDK 11 is installed in Raspbian, I need to add Open JFX in order to create GUI:s? Is that correct? Or is Open JFX a...

Java IDE for Pi 4 - need to create simple GUI

As I understand the Java SDK 11 is pre-installed at the pi4. I need to create a rather simple GUI with some code behind it reading and writing to GPIO. I use Raspbian at the pi. What Java IDE would you recommend to use? Without to much fuzz, I'm new to Raspberry, Raspbian and Java, coming from the W...

Re: Can bus Shields

This sounds interesting to me also. Will it work with a Rpi 4 as well? How close to a final working product are you

Re: Can bus Shields

Interesting. What makes you create your own shield rather than buy one from Seeed or SKPang for very less money?

Can bus Shields

Hi, new to Raspberry I have recently bough a Rpi4. I'm working on a project with my car, planning to create a modern infotainment system in the now 20 year old car. Having played around already with an Arduino with a can bus shield I instead moved to Raspberry since the Arduino is very limited in wh...

Re: GUI interface and access to IO

I checked out the QTCreator, it looks interesting but rather expensive? One user license for QTCreator is $5508 for a one year license. About on par with a full version of Microsoft Visual Studio but not what I was looking for. Maybe there is a way to use it for less money? Otherwise I will have to ...

Re: Pi 4 C# App, WebClient.DownloadString not working

Are you running your C# code at Win 10 IOT at the pi, or is it a .NET Core application running within Linux?

Re: GUI interface and access to IO

Since you will be running Linux (Raspbian?) on the pi and now need to create a GUI for your application, C# should not be an option as I understand it. The .NET Core application family that can be run at Linux as well as other operative systems won't give you tools for building GUI. And otherwise an...
