The hackers over at, a Zagreb Makerspace, have been hard at work designing the ULX3S, an open-source development board for LATTICE ECP5 FPGAs pass gas in spanish. This board might help make 2019 the Year of the Hacker FPGA, whose occurrence has been predicted once again after not quite materializing in 2018. Even a quick look at the board and the open-source development surrounding it hints that this time might be different. Bottom side of ULX3S PCB

The ULX3S was developed primarily as an educational tool for undergraduate-level digital logic classes. As such, it falls into the “kitchen sink” category of FPGA boards, which include wikipedia electricity consumption a comprehensive suite of peripherals and devices for development, as opposed to more bare-bones FPGA breakouts. The board includes 32 MB SDRAM, WiFi via an ESP-32 (supporting over-the-air update), a connector for an SPI OLED display, USB, HDMI, a microSD slot, eight channels of 12-bit ADC (1 MS/s), a real-time-clock, 56 GPIO pins, six buttons, 11 LEDs, and an onboard antenna for 433 MHz FM/ASK. This seems like a great set of I/Os for both students and national gas average 2007 anyone else starting FPGA development.

The ULX3S supports members of the Lattice ECP5 FPGA family, ranging from the 12F (12 k LUTs) to the 85F (84 k LUTs). What can you do with this much FPGA horsepower? Have a look at the long list of examples curated in the ULX3S Links repo. There, you’ll find code from retro-computing to retro-gaming, the usual electricity billy elliot backing track LED and HDMI demos, and even Linux running on a mor1kx OpenRISC core. Maybe the most interesting links in the repo, however gas after eating yogurt, are those that show how to program the FPGA with a completely open-source toolchain. Proprietary toolchains are the last link keeping some vendor’s FPGAs from wider adoption in the OSHW community, and it’s great to see people chipping away at them.

The board itself is completely open-source. In the GitHub repo, you’ll find the KiCAD 5 design files for the PCB released under an MIT-style license. Even more impressive is the advice electricity 101 youtube in the README, which not only welcomes independent production of the boards, but gives some solid advice on dealing with PCBA vendors during manufacture. Our own advice is to do the right thing and offer the developers a cut if you decide to independently market this board, even though you aren’t required to by the license. If want one, but don’t want to manufacture your own, you can contact static electricity bill nye full episode the developers using the email or gitter links at the bottom of the ULX3S page: they’re currently doing a small production run.

Classic battles: PC vs Mac, Emacs vs Vi, Tastes Great vs Less Filling, and certainly one that we debate around the Hackaday watercooler: command line or IDE? There’s something to be said for using gas and water llc good old command line tools, and even if you like to configure your favorite editor to be nearly an IDE, at least it is one you are familiar with and presumably leverage over several different uses.

[Rochus-Keller] says there’s more to come. However, even at this early stage the IDE does syntax coloring, tooltips, inline messages, and can analyze source code allowing you to cross-reference symbols as you’d expect. There are configurations for Icarus to do simulations or you can use Verilator or Yosys — the synthesizer behind IceStorm. It appears it can also interact with Tcl-based workflows like those used by most FPGA vendor IDEs.

There’s quite a bit still on the gas efficient cars under 5000 to-do list, so we are excited to see where this is going. QtCreator isn’t hard to learn and it doesn’t’ feel as bloated as some of the big IDEs like Eclipse. If you want a quick introduction to QtCreator, we did that already. If you want to draw boxes instead of writing Verilog directly, try IceStudio. Posted in FPGA Tagged FOGA, icestorm, ide, qtcreator, verilog, yosys b games car

Last time I talked about how I took the open source Verifla logic analyzer and modified it to have some extra features. As promised, this time I want to show it in action, so you can incorporate it into your own designs. The original code didn’t actually capture your data. Instead, it created a Verilog simulation that would produce identical outputs electricity clipart to your FPGA. If you were trying to do some black box simulation, that probably makes sense. I just wanted to view data gas gangrene, so I created a simple C program that generates a VCD file you can read with common tools like gtkwave. It is all on GitHub along with the original files, even though some of those are not updated to match the new code (notably, the PDF document and the examples).

If you have enough pins, of course, you can use an external logic analyzer. If you have enough free space on the FPGA, you could put something like SUMP or SUMP2 in your design which would be very flexible. However, since these analyzers are made to be configurable from the host computer, they probably have a lot of circuitry that will compete with yours for FPGA space. You configure Verifla at compile time which 1 unit electricity cost in bangalore is not as convenient but lets it have a smaller footprint.
