Reverse Engineering Lattice’s iCE40 FPGA Bitstream
Unlike microcontroller projects, projects involving FPGAs cannot yet claim to rely on a mature open-source toolchain. Each FPGA will, at some point, need to be configured with a proprietary bitstream...

An Open Source Toolchain For iCE40 FPGAs
FPGAs are great, but open source they are not. All the players in FPGA land have their own proprietary tools for creating bitstream files, and synthesizing the HDL of your choice for any FPGA usually...

Hackaday Prize Entry: They Make FPGAs That Small?
There are a few development boards entered in this year’s Hackaday Prize, and most of them cover well-tread ground with their own unique spin. There are not many FPGA dev boards entered. Whether this...

FPGAs For The Raspberry Pi
FPGA development has advanced dramatically in the last year, and this is entirely due to an open-source toolchain for Lattice’s iCE40 FPGA. Last spring, the bitstream for this FPGA was reverse...

Hackaday Links: November 29, 2015
The Raspberry Pi Zero was announced this week, so you know what that means: someone is going to destroy a Game Boy Micro. If you’re interested in putting the Zero in a tiny handheld of your own design,...

Does the World Need an FPGA Arduino?
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? Fortunately,...

The Open Source Hacker’s Laptop
[Tsvetan Usunov] has been Mr. Olimex for about twenty five years now, and since then, he’s been through a lot of laptops. Remember when power connectors were soldered directly to the motherboard?...

STM32 and FPGAs In A Tiny Package
Slowly, very slowly, the time when we don’t subject embedded beginners to AVRs and PICs is coming. At a glacial pace, FPGA development platforms are becoming ever more capable and less expensive. [Eric...

Hackaday Links: November 6, 2016
Here’s a life protip for you: get really, really good at one video game. Not all of them; you only want to be good – top 10% at least – at one video game. For me, that’s Galaga. It’s a great arcade...

Adding IceZero To The Raspberry Pi
[Kevinhub] noticed there were quite a few FPGA hats for the Raspberry Pi. Instead going out and buying one of these boards like a filthy commoner, he decided to spin up his own FPGA Pi accessory. This...

Lattice iCE40 FPGA Configured by Linux Kernel
The Linux kernel recently added support for loading firmware into an FPGA via the FPGA Manager Framework. [OpenTechLab] has built a driver for the Lattice iCE40 FPGA (same chip used on the iCEStick and...

An Ultrasound Driver With Open Source FPGAs
Ultrasound imaging has been around for decades, but Open Source ultrasound has not. While there are a ton of projects out there attempting to create open ultrasound devices, most of this is...
View ArticleThree Part Deep Dive Explains Lattice iCE40 FPGA Details
It is no secret that we like the Lattice iCE40 FPGA. It has a cheap development board and an open source toolchain, so it is an easy way to get started developing low-cost, low-power FPGA designs....

Icestorm Tools Roundup: Open Source FPGA Dev Guide
We like the ICE40 FPGA from Lattice for two reasons: there are cheap development boards like the Icestick available for it and there are open source tools. We’ve based several tutorials on the Icestorm...
View ArticleProgramming A RISC-V Softcore With Ada
We were contacted by [morbo] to let us know about a project on the AdaCore blog that concerns programming a PicoRV32 RISC-V softcore with Ada. The softcore itself runs on a Lattice ICE40LP8K-based...
