Lattice iCE40 Ultra Plus FPGA: Gnarly Grey Upduino – Tutorial 1: The basics

A how-to getting an LED flashing using VHDL from Harris’ Electronics: The cheap price however comes with a few niggles, namely getting it up and running in the first place with the limited documentation. Gnarly Grey do a great job of explaining programming a starting program but don’t say much about further development. With that […]

An open source frequency meter and clock generator

Boris Landoni writes about an open source project frequency meter and clock generator: On the hardware of the controller board LED Matrix, by taking advantage of the reconfigurability of the onboard FPGA, we can build a bivalent tool that is extremely useful to have on our work bench. Via Open Electronics.

Yellowstone JTAG debugging

A follow-up to the FPGA-based disk controller for Apple II post, Steve writes: After a month of inactivity, I finally returned to my unfinished Yellowstone disk controller project to investigate the JTAG programming problems. Yellowstone is an FPGA-based disk controller card for the Apple II family, that aims to emulate a Liron disk controller or other models […]

FPGA-based disk controller for Apple II

Steve Chamberlin over at Big Mess o’Wires has been working on an FPGA-based disk controller for Apple II, which he call Yellowstone: Apple II disk controller cards are weird, there are a crazy number of different types, and many are rare and expensive. Can an FPGA-based solution save the day for retro collectors? You bet! Nearly […]

BML USB 3.0 FPGA interface over PMOD

An open-source-hardware USB 3.0 to FPGA PMOD interface design from Black Mesa Labs: Black Mesa Labs is presenting an open-source-hardware USB 3.0 to FPGA PMOD interface design.  First off, please lower your expectations. USB 3.0 physical layer is capable of 5 Gbps, or 640 MBytes/Sec. This project can’t provide that to your FPGA over 2 […]

BML HDMI video for FPGAs over PMOD

Here are two open-source-hardware HDMI  video boards for adding digital video to FPGA platforms with standard PMOD connectors from Black Mesa Labs: The BML 3bit HDMI over single-PMOD uses 7 of 8 available LVCMOS 3.3 pins on a single PMOD to provide 3bit color ( R,G,B 100% On or Off ). Example Verilog design drives 800×600 […]

Old, not obsolete. Working with the Xilinx Virtex-E FPGA in a huge BGA package

Andy Brown not only did a nice write up about his experience with the Xilinx XCV600e FPGA and creating a development board for it, but he also did a great video walkthrough: The general aim of this project will be to create a generic development board for the FPGA. This isn’t as simple as it […]

Ambient TV lighting, a low-power solution for creating ambient light based on a TV signal

Here’s an ambient TV lighting project by Shiva Rajagopal from Cornell University, built as a final project: Here’s a project I recently made for the ECE 5760 FPGA class at Cornell University. I have created a real-time system that can use an NTSC video signal to simulate the lighting effects of a TV in a […]

Nanocounter is an accurate frequency counter using an FPGA, STM32 and a bluetooth android app

Andy Brown has designed and built a frequency counter using an FPGA, STM32F072 and an Android GUI – the Nanocounter: After studying the above counting methods I decided on the following goals for my frequency counter, which I’m going to call Nanocounter. Very accurate measurement over a range of 1 to 50MHz. This would cover the range […]

How do I FPGA?

TC-Engineering writes: I’ve been thinking about building stuff with FPGA’s for a while, and usually get turned away because FPGA’s are considerably harder to implement than microcontrollers since they have no on-chip memory. It is necessary to re-program the gates every time they power up, which requires an external flash memory chip. There aren’t great […]

Implementing a multi-peripheral controller using a tiny mixed-signal FPGA

Max Maxfield over at the Embedded.com writes: As you may recall from previous columns, I tend to think of Silego’s GPAK chips as being super-small mixed-signal FPGAs that you can literally design and program in just a few minutes, and that cost only a few cents each. Well, the folks at Silego were so excited by […]

Announcing the STREAM board

The Myriad crew  has announced the new Stream board released through the MyriadRF initiative for doing SDR with the LMS6002D/LMS7002M from Lime Microsystems. It’s a fully Open Source board with Kicad design files and a fully Open Source OpenRISC SoC for the FPGA: We are thrilled to announce that the STREAM board is the latest project […]

TAPR/DCC video: System on a Chip – Programming FPGAs for Mixed Signal Systems

Here is the first of a four-part video series recently posted from the 2014 TAPR/DCC conference in Austin, TX. This is from the DCC’s Sunday Seminar, “a four-hour deep dive” into a single subject, in this case FPGA programming for mixed signal systems. “The presenter is amateur radio operator Chris Testa KD2BMH who is designing […]

An FPGA sprite graphics accelerator with a 180MHz STM32F429 controller and 640 x 360 LCD

Here’s a cool open source FPGA graphics accelerator board by Andy Brown. Check out the full write-up here: In this project I’m going to attempt to design and build a sprite-based graphics accelerator that will function as a co-processor to an MCU. Using cheap off-the-shelf components I’m hoping to achieve a level of gaming performance that […]

FPGA : RC Servo and Stepper motor control in Verilog

Trandi blogged about his RC servo and stepper motor project.  He writes: For those interested in reproducing this example: The board is called “EP2C5 Mini Board” and has a EP2C5T144C8 Cyclone II FPGA on it I used a standard, 9grams micro RC Servo I used a 28BYJ-48 stepper motor and it’s driver (you can purchase these […]
