YouTuber My Developer Thoughts, a self-confessed middle-aged Software Developer, clearly has a real soft spot for the 6502-based 8-bit era machines such as the Commodore 64 and the VIC-20, for which he has created several video tutorials while travelling through retro-computing. This latest instalment concerns bringing up the toolchain for using the Kick Assembler with VS Code to target the C64, initially via the VICE emulator.
The video offers a comprehensive tutorial on setting up the toolchain on Windows from scratch with minimal knowledge. While some may consider this level of guidance unnecessary, it is extremely helpful for those who wish to get started with a few examples quickly and don’t have the time to go through multiple manuals and Wikis. In that regard, the video does an excellent job.
VS Code is a great tool with a large user base, so it’s not surprising that there’s a plugin for using the Kick Assembler directly from the IDE. You can also easily launch the application onto the emulator with just a push of a button, allowing you to focus on learning and working on your application. Once it runs under emulation, there’s a learning curve for running it on native hardware, but there are plenty of tutorials available for that. While you could code directly on the C64 itself, it’s much more pleasant to use modern tools, revision control, and all the conveniences and not have to endure the challenges.
Once you’ve mastered assembly, it may be time to move on to C or even C++. The Oscar64 compiler is a good choice for that. Next, you may want to show off your new skills on the retro demo scene. Here’s a neat C64 demo with a twist. There is no C64.
Thanks to [Stephen] for the tip!
For decades now, we’ve been able to quickly and reliably interface musical instruments to computers. These tools have generally made making and recording music much easier, but they’ve also opened up a number of other out-of-the-box ideas we might not otherwise see or even think about. For example, [Joren] recently built a human interface device that lets him control a computer’s cursor using a flute instead of the traditional mouse.
Rather than using a MIDI interface, [Joren] is using an RP2040 chip to listen to the flute, process the audio, and interpret that audio before finally sending relevant commands to control the computer’s mouse pointer. The chip is capable of acting as a mouse on its own, but it did have a problem performing floating point calculations to the audio. This was solved by converting these calculations into much faster fixed point calculations instead. With a processing improvement of around five orders of magnitude, this change allows the small microcontroller to perform all of the audio processing.
[Joren] also built a Chrome browser extension that lets a flute player move a virtual cursor of sorts (not the computer’s actual cursor) from within the browser, allowing those without physical hardware to try out their flute-to-mouse skills. If you prefer your human interface device to be larger, louder, and more trombone-shaped we also have a trombone-based HID for those who play the game Trombone Champ.
