Episode #038 - IRQ Driven Animations
In our previous episodes, we've been using a quite primitive animation technique. We've been simply advancing frames in an infinite loop with and wasting enough time with a delay macro to slow the animation down. Not only we don't have an easy way to control the exact speed of animations using this technique. But the amount of delay needs to be updated whenever we add or remove any code to run in this loop. Fortunately there is a different way. And I'd like to use this opportunity to introduce one of the most exciting features of the 6510 processor that powers the Commodore 64 - the interrupt handling.

I learned assembly the hard way, with only limited documentation. Although part of the fun is in discovering all these things yourself, I think such screencasts could have helped me in getting up to speed faster. They do contain some nice bits of information :)

64bites brings me closer to understanding a computer I learned to love long ago, and still do. More than anything, it is really fun to follow the lessons and I always look forward to the next episode with great anticipation. It is the best thing since chocolate.

This is really cool. I don't know exactly how popular it will end up being, but there is always room online for things like this.
