Auto-Launch Raspberry Pi Apps

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.

Raspberry Pi and Xojo: Configure for Remote Access

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).

Easy as Pi: GPIO updates

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. Especially since Xojo 2019r1 when building for Pi Desktop and Console is free with Xojo Pi!

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.

Headless Pi: Using Xojo and Raspberry Pi Without a Display

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.

My Raspberry Pi 2 sits on my desk next to one of my speakers. It’s not hooked up to any display. I use a combination of SSH, SFTP and VNC when I need to work with it.

Raspberry Pi 3 Announced!

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!
