Downloading

Maybe you think that Ultibo core looks interesting but you're not quite sure if it really is what you are looking for. An easy way to see some of what Ultibo core is capable of is to run the demo image. If you already have a Raspberry Pi available (many people do) then it should take no more than a few minutes to get the demo up and running.

The demo runs for about 3 minutes and covers a range of features like using the console, creating threads and accessing files. At the end of the demo you can explore more of what Ultibo core has to offer, just follow the information on the screen.

The most recent version of the demo image can always be found via the link on the download page, simply save the downloaded zip file to a folder somewhere on your computer.

Installing

Installation of the demo image is very easy and can be done using Windows, Mac OS X or Linux. On Windows simply double click the zip file to open it (or you can use another tool such as 7-Zip) and extract the files it contains to the root directory of a FAT formatted SD card. On other operating systems use the appropriate tool to open or unzip the file and copy the contents to an SD card.

The zip file contains just 14 files but this is all you require to make it work, Raspberry Pi (Models A, B, A+, B+, Zero, Zero W and Zero WH), Raspberry Pi 2B, Raspberry Pi 3B/3A+/3B+/CM3/CM3+/Zero2W and Raspberry Pi 4B/400/CM4 are supported by the demo image.

Once you have copied the files simply insert the SD card into the slot in your Raspberry Pi, connect a monitor to the HDMI port and plug the power cable into your Raspberry Pi. After about 2 or 3 seconds you should see a welcome message appear on the monitor. If you don't get a welcome message or you don't see anything, power off your Raspberry Pi, check that the SD card is inserted correctly and that the monitor is connected and powered on and try again.

If you have a wired network available you can also connect a network cable before starting the demo to enable additional features. Optionally, if you connect a USB keyboard you will be offered the option to rerun the demo once it is complete.

Please note that Raspberry Pi 4B/400 support is still in progress and currently USB is only available if you power the Pi via the 40-pin header and connect a USB hub to the USB-C connector (the OTG port). Work is ongoing to complete the drivers for the new USB controller and will be released as soon as it is completed.

Latest version

The demo image will be periodically updated to reflect new releases and highlight new features as they become available.

Latest version of the demo image is 1.0.15

(Compiled using Ultibo core 2.6.001)

What next?

If the demo image makes you want to know more about what you can do with Ultibo core, and how, then we recommend you have a look at the example projects included with the Ultibo core installation. The examples start at the classic Hello World and go through a number of different topics to end at a simple web server which you can use to serve web pages.

Even if you are an experienced Free Pascal programmer it would be a good idea to have a quick look through the examples just to pick up some information on where to start creating applications with Ultibo core.
