My CodeClub loved their first session with the Astro-Pis. They particularly enjoyed displaying text on the LED matrix and were keen to create images like the space-invader that comes with the examples.
Obviously you can make these up directly in Python by making a list and loading it by the API, but this can be tricky in terms of colour design and involves lots of squinting.
When we made the TechWillSaveUs DIY gamers last year, they produced a simple Windows App for creating images for the monochrome matrix this device had.
I thought I’d try to knock up a similar application for Raspbian using pygame. There are a few programs for Windows and online that do a similar job, but I wanted something that would run natively on the Pi.
My app allows you to create patterns using the colours selected by the buttons on the righthand side.
You can then export this 8×8 pixel image to a png (filename is image8x8.png), print the corresponding Python list to the console or load it directly onto the Astro-Pi LED matrix.
