Count Your Bristles!

Posted by: Dave Vandenbout in Blog Post 6 years ago

Well, it's Thanksgiving in the USA. A few years ago, at a gathering of my girlfriend's family, we each made lists of things we were thankful for. "Family" and "togetherness" appeared quite a bit, but my list, naturally, was a bit different - it had things like "clean water" and "absence of minefields" on it. <<more...>>

Repos, Repos, Repos ...

Posted by: Dave Vandenbout in Blog Post 6 years, 1 month ago

I wrote last month about using Upverter, and now there's a new OSHW repository on the scene: Solderpad. While Upverter is trying to provide both cloud-based design tools and a repository, Solderpad has taken a more modest path and provides only a place for you to store your designs after you've used whatever tool you want to create them. So you might ask how that's any different from just storing your design on Github. Well, in addition to the Git-based repository, Solderpad adds these capabilities: <<more...>>

How to Learn VHDL

Posted by: Dave Vandenbout in Blog Post 6 years, 1 month ago

As FPGAs work their way into the hobbyist/maker community, I'm guessing a lot of you are trying to learn VHDL and Verilog. (You can try to use schematics, but the Xilinx editor is pretty poor.) Which language you choose is up to you, but I'll only talk about VHDL in this post. There's general agreement that if you know one, it's easy to learn the other.

There's no shortage of VHDL books (around 100 on Amazon) or online tutorials (Google lists 278,000 but I haven't checked them all), so there's no need for me to waste my energy doing another. Instead, what I will do is tell you how to use the existing books & tutorials to learn the use of VHDL in synthesizing logic for FPGAs.

Upverter: You Don't Have To Be Open, But You Do Need To Be Good.

Posted by: Dave Vandenbout in Blog Post 6 years, 2 months ago

Upverter is a website/service that allows people to collaborate on hardware designs. It looks like they've got some VC funding and they're pitching themselves to the OSHW community as the place to store their designs.

A DangerousPrototypes blog post called Upverter a "closed source vampire" for trying to profit from the OSHW community while still keeping their web-based tools closed. Kinda harsh. <<more...>>
