Sparkfun sells a PSoC dev board with a lot of features: “I’d like 1000 gold-pressed Latinum in one foot lengths” But not Mericans!!! no they still use imperial lol. The people that invented Imperial – now use metric. I for one won’t be putting any effort into learning Verilog just to suite Mericans. And that makes me wonder why I even see it on HaD which is a global website? I dunno why ? Do you design in VHDL then convert to Verilog for ASIC production?Īnyway – choosing Verilog makes your product and American Domestic product and not an international product. The rest of the worlds seems to be using VHDL (exclusively). It only has a strong hold in Merica as far as I know. I think that the reason that there is so much use of Verilog in Merica is that all the old IP was written in Verilog. BUT … If you were never into the hardware then you probably know nothing about schematic entry. Verilog is more abstracted away from hardware and that isn’t a problem if you were never into the hardware anyway. Most people that have enough experience to use schematics normally prefer VHDL as the two are closer together. Then it has Verilog which doesn’t make sense again. So not as bad as I suggested but still too big for any reasonable schematic entry. Really … if you don’t need the number of pins then you would choose a smaller package unless you needed more LUTs. Much smaller than I expected for a QFP144.

This project is clearly in its very early stages, but we can’t wait to see how it shakes out. Putting an FPGA into an Arduino-compatible form-factor and backing it with an open GUI is an interesting idea. We’ve been seeing FPGA projects popping up all over, and with the open-source toolchains making them more accessible, we wonder if they will get mainstreamed the lure of reconfigurable hardware is just so strong. Everything’s up on GitHub, but not yet ported to KiCad, so you can tweak the hardware if you’ve got a copy of Altium. Still, it’s more I/O than you get on a plain-vanilla Arduino, so we’re not complaining too loudly. One of the main attractions of FPGAs in our book is the tremendous availability of fast I/Os. That leaves around a hundred potential I/Os unaccounted-for. There are eight user LEDs on the board, plus the 28 I/O pins that end in pinheaders. The iCE40 FPGA has 144 pins, so you’re probably asking yourself where they all end up, and frankly, so are we. (Hackaday.io has two Arduino clones using SVG pinouts: in SMT and DIP formats.) This is great for attaching small, powered sensors using a three-wire cable like the one that you use for servos. But they’ve also doubled them with pinheaders in a more hacker-friendly layout: SVG - signal, voltage, ground. The Alhambra board itself looks to be Arduino-compatible, with the horrible gap between the rows on the left-hand-side and all, so it will work with your existing shields. Now we know - it’s the support software for an FPGA “Arduino”. Indeed, we were wondering what the BQ folks were up to when they were working on an easy-to-use GUI for the FPGA family. It’s based on the Lattice iCE40 FPGA, which we’ve covered previously a number of times because of its cheap development boards and open-source development flow. The page also contains Arduino sketch examples.What would you get it you mashed up an FPGA and an Arduino? An FPGA development board with far too few output pins? Or a board in the form-factor of Arduino that’s impossible to program?įortunately, the ICEZUM Alhambra looks like it’s avoided these pitfalls, at least for the most part. It can also be used with the QLG1, QLG2 or QLG2-SE GPS receiver modules, and popular AD9850 DDS modules.Ī printed assembly manual is not supplied with the kit please download them from the Arduino shield kit page. It is compatible with the QRP Labs LPF kit, QRP Labs Si5351A module kit, QRP Labs OCXO/Si5351A module kit, and QRP Labs relay-switched LPF kit. The kit contains PCB, Arduino headers for connection to an Arduino Uno, Reset button, 4-way headers for plugging in an LPF module, two 10-way headers for plugging in a frequency synthesiser module, necessary components for a QRP power amplifier (around 1/4 Watt on 30m band varies depending on band), and BNC connector for RF output.Īn Arduino board and a dditional plug-in modules should be purchased as required for your intended application. This kit is an Arduino shield kit only (additional items are shown in some of the photographs, to illustrate possible applications).
