Customers Care About Their Shit, Not Mine!

Posted by: Dave Vandenbout in Blog Post 3 years, 9 months ago

I re-factored the library of VHDL modules for the XuLA and XuLA2 boards last week (that's fancy talk for cleaning up the shit that had accumulated in it). Basically, I built a single, merged library that could be used for both types of boards even though they're based on different FPGA families. <<more...>>

Dev Boards and the Gym

Posted by: Dave Vandenbout in Blog Post 3 years, 10 months ago

It struck me the other day that a lot of people buy development boards the way they buy a music CD (I know nobody buys music CDs anymore, but stick with me): they pick something that's popular with their crowd, look for the cheapest place to get it, and then bring it home with expectations of how great it will be. <<more...>>

XuLABee - The 1980's Microbee Home Computer Reimagined with an FPGA

Posted by: Dave Vandenbout in Blog Post 4 years, 1 month ago

the 1980's Microbee home computer I ran across a blog by Brad Robinson about his efforts to build the 1980's Microbee home computer using FPGAs. One implementation uses a XuLA2 board and a custom PCB to fit the Microbee into a small case that attaches to a keyboard and monitor. All the steps in developing the circuitry and FPGA code are clearly documented in a series of blog posts. <<more...>>

Teaching Programmable Logic to Programmers

Posted by: Dave Vandenbout in Blog Post 4 years, 1 month ago

PyOhio and MyHDL logos Teaching programmers how to use programmable logic like FPGAs: you would think that was easy, right? Chris Felton recently gave a workshop at PyOhio to do just that. The intent was to help programmers learn FPGA programming techniques using the MyHDL Python package. To support his workshop, Chris put together a complete hardware and software setup for the programmers that consisted of: <<more...>>

VirtualBoy TV-mod Using a XuLA

Posted by: Dave Vandenbout in Blog Post 4 years, 1 month ago

VirtualBoy scanned LED array There's a nice write-up over on the Furrtek site about modding the 1990's-era VirtualBoy table-top video game console. The VB provides a 3D gaming experience using two scanned LED arrays, one for each eye. A XuLA-200 was inserted into the VB's case in order to generate VGA signals so the game action could be seen on an external monitor. <<more...>>
