FPGA-based disk controller for Apple II

Friday, January 12th, 2018

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...

How do I FPGA?

Friday, March 4th, 2016

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...

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

Thursday, October 8th, 2015

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...

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

Friday, December 12th, 2014

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...

VGA framegrabbing with TVP7002

Thursday, February 13th, 2014

[embed]http://www.youtube.com/watch?v=8bmWkqSN7pw[/embed] desaster blogged about his VGA framegrabber project: The project got a nice boost when I found TVP7002 on TI’s site. It’s a video digitizing chip, featuring 3x ADC (one for each color channel) and a PLL system for generating the pixel clock from the HSYNC input. Compared to alternatives, this seemed...
