EEBookshelf: Anti-aliasing and Sub-Pixel Rendering
While this is neither and app-note nor a book, I’ve been interested in anti-aliasing for quite some times since A.) UI design is just kind of a fetish of mine, and B.) There’s almost no useful information out there on this stuff in a form that’s appropriate to low-cost embedded systems. Which is where this weeks EEBookshelf entry comes in: a very old article (think Quick Basic, ya … that thing you used back in High School or earlier) explaining the basics of anti-aliasing pixels. While the text is obscenely small, the explanation is very clear, and it’s easy to transfer this to your own firmware in C or whatever else. Now to work this into some of my own projects and see how far I can stretch the 72MHz on the LPC1343 and the few hundred KBs I have left! 🙂 See QB EXpress: Issue #22 for this article from Eclipzer. My advice … if you find this useful save it to a PDF somewhere special.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

Anyone interested in graphics on low powered systems with small displays (either 1990s PCs or 2012 embedded processors) might be interested in Mike Abrash’s books “Zen of Graphics” and “Zen of Assembly Language” which he combined and published (free) as “Games Programming Black Book”.
