For the past couple of weeks I’ve been working on refactoring the whole OpenGL plugin to better support Raspberry Pi.
The new release of the Raspberry Pi operating system called Raspbian Stretch has Qt 5.7 built in and comes with FFMPEG instead of libav. This is great news for Fugio as it’s much more in line with the libraries we’ve been using.
I’m busy building Fugio on my Raspberry Pi 3 (not cross compiling) as I type, although I wouldn’t recommend trying this yourself just yet as it needs some work to get it compiling.
With this latest update, I should be able to create a binary repository for installing Fugio onto Pi’s without compiling.
As ever, this is loads of work that will be available to everyone for free, so if you can, please consider supporting the project by donating just $1 a month via Patreon.
Also, check out the first look at my new projector blending tool that Fugio will support for multi-screen projections.
This week work has continued on doing fun things with Raspberry Pi’s!
One key thing I need to be able to do is control patches remotely. While there are already plenty of options for sending and receiving pin data (see the updated Network plugin documentation), there is no possibility for using a text editor remotely while retaining syntax highlighting and error reporting, which are both very helpful when hacking shaders and scripts.
The dream being that I can have an editor on a laptop and remotely live code a shader on a Raspberry Pi.
So I’ve refactored the syntax highlighting and syntax error reporting system to facilitate sharing this information remotely. Next up is writing a couple of nodes for sending and receiving this information over a network.
This should even work over the internet, which opens up some interesting remote collaborative options!
You’ll also notice in the image at the top, I’ve updated the Text Editor to show errors by highlighting the line numbers in red, which is a lot clearer.
I also enabled sending keyboard events from one Fugio to another, which should also prove useful in the future.
Finally, I wanted to highlight this new patch by Winfred Nak that he posted up in the Fugio Users Group on Facebook. It’s a rather cool game show buzzer where the first button pressed will trigger off the music for that team. It’s a good application of logic nodes, which are really useful!
If one was so inclined, one could add a Firmata node and use an Arduino and real physical buttons as inputs…
It’s been a long term goal for me to get Fugio running on Raspberry Pi.
If you’ve not come across them before, they are cheap, credit-card size computers than can run a full desktop experience with mouse and keyboard support, networking, HD video playback, and even a GPU for 3D graphics.
I use them a lot for installations where I need seamlessly looping video playback, but I really want to develop artworks on them, so I can use them instead of leaving bulky and expensive computers in a gallery for months.
So, this week I’ve updated the source code to allow it to compile and run on a Raspberry Pi 2 (and 3). Everything works apart from PortAudio, which I’ll get to in due course.
