For XDC 2016 I needed a way to demonstrate a Raspberry Pi app that used the GPIO and updated an LCD character display. But I didn’t really have access to a screen that I could use to show the desktop so that I could run the app. And I could not remotely connect to the Pi because I did not have a good way to get it on the wifi network in the first place.

Here’s how you can create a simple music player app for your Raspberry Pi that can play mp3 and aac (m4a) files from a folder.
Just in time for Xojo 2017 Release 1 and its Remote Debugger for the Raspberry Pi, we released a new book “Programming the Raspberry Pi with Xojo”. The book contains 19 chapters that introduce you to the Raspberry Pi, takes you through setting it up, and covers learning about Xojo programming for the Pi. The book includes 8 step-by-step projects for creating a variety of Xojo apps for the Raspberry Pi, including: a text adventure, a music player, a game, Internet access, a web app, plus hardware projects.
Using the Remote Debugger means that you can run Xojo apps on the Pi for testing and development without have to first purchase a Xojo license.
Xojo is a superb choice for developing and deploying apps for Raspberry Pi. After all, Xojo not only simplifies making the User Interface of your apps via drag and drop, it’s an object-oriented and event oriented programming language that builds native Linux apps based on the ARM processor architecture for the Raspberry Pi (among other platforms).
In this episode of XojoTalk, Paul talks with Jim Meyer, who uses Xojo for NCAA stat tracking, home automation, workflow automation and much more.
Xojo is similar to VB, Java and C#
The Xojo programming language is fully object-oriented and uses an object model that is quite similar to VB, Java and C#. If you are used those languages at all, you’ll be right at home with Xojo.
Available since 1998, Xojo was one of the first languages to use Automatic Reference Counting (ARC), something that other languages such as Swift and Objective-C now use. Xojo is type-safe and fully object-oriented making it easy to learn and use, but it also has advanced features such as namespaces, extension methods, exception handling, introspection, delegates and more.
We are always keen to see apps and projects that Xojo developers have made for their Raspberry Pi 2 and Raspberry Pi 3 single-board computers. I am pleased to announce some updates to our GPIO project to make it even easier to use more types of hardware in your Raspberry Pi projects.
You don’t need to hook up your Pi to a physical display, keyboard and mouse. You can set up VNC on the Pi so you can remotely connect to it.
On Monday February 29th, the Raspberry Pi Foundation announced the new Raspberry Pi 3. This updated Pi has some significant improvements over the Pi 2, including:
- A 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU (~10x the performance of Raspberry Pi 1)
- Integrated 802.11n wireless LAN and Bluetooth 4.1
- Complete compatibility with Raspberry Pi 1 and 2
That last bullet point is notable because it means that Xojo is also fully compatible with the new Raspberry Pi 3!
