Announcing the Audiofab Easy Spin (FV-1) Visual Studio Code Extension

Post by mark_melvin »

Hello Everyone,

Audiofab is pleased to announce that over this past Thanksgiving weekend, we've had more than just turkey cooking in the oven! We've been working on an improvement to our original FV-1 programming tool, and it is finally ready for some beta testing.

Introducing the Audiofab FV-1 Visual Studio Code extension! Now you can edit and assemble FV-1 programs right from the comfort of VS Code. Not only does this provide an editor for .spn files with syntax highlighting it also allows you to assemble and program the EEPROM of your Easy Spin device using the Audiofab USB programmer right from the editor! If you aren't using an Audiofab device, you can still edit and assemble your files in VS Code, and output a .hex file for flashing with your own device.

We're pretty excited about the potential of this new platform, and we have tons of ideas on how to improve it in the future. If you have a mind to, give it a whirl! If you find any issues, please file an issue in our Issue Tracker and we'll look into it as soon as possible.

To install it, click the link above, or just search for "Audiofab" in the VS Code extension Marketplace.

Cheers,
Audiofab

Hello All,

Happy Thanksgiving! Just a quick update on our FV-1 programming extension. We've been hard at work over the past month or two adding functionality and if you're into FV-1-based effects at all, we think you're going to like what we've been building!

Here's a video walkthrough of the the various features in the extension:

We've got a cool new experimental feature - block diagram programming!

Check out the extension in the VS Code Marketplace and on Github. All feedback is welcome!

Hello Everyone!

Just a note to say that on the weekend we shipped a HUGE new release of our VS Code extension. We now have a full simulator with source-level debugging available in VS Code!

You can simulate both block diagrams, or traditional .spn files. We also have completely overhauled the assembler behind the scenes, and crafted some extensive documentation for you here:

Information on the simulator is available here:

You can even take a crack at building your own blocks and loading them into the block diagram tool.

If you make something cool, let us know!

Cheers!
Audiofab
