Over the past year, I took a shot at designing a Zynq-7000-based development board. I am now considering an update to my first board --...

Over the last few months, I have continued to experiment with my Zynq-7000 board . My board has been running well and is very stable. The...

I am hoping to get audio support for my custom Zynq-7000 development board. After a little digging into options, I am currently focusing...

As my custom Zynq-7000 board has been working fairly well (see my previous blog post ), I have been learning about PetaLinux. I am...

Recently, I have been working on different MCU and FPGA development boards. The FPGAs to this this point have been simpler, or older,...

I have a batch of Xilinx XC5215-PQ160AKMOO21 FPGAs. These are old FPGAs and it will be a challenge (if not impossible for me) to get one...

I am just beginning to work on a dev board for a Xilinx Spartan XC3S200AN-FTG256AGQ1413. I plan to use this page to capture information...

As part of my post on MCUs, I added a Lattice iCE40 FPGA to the mix. While I have done a little bit of work with FPGAs in the past, it...

I am hoping to learn more about processors by building a 16-bit processor. I previously built an 8-bit processor based on Ben Eater's...

I have recently started using programmable logic devices (PLDs) in some of my projects. Below are the steps I am using, along with some...

I've made some decent progress getting my FPGA VGA working on my 6502 system. My goal is to have a "smart display" to replace the current...

Below is the configuration I used to get the Xilinx Video Test Pattern Generator (TPG) working on a Digilent Cmod A7 FPGA. This is based...

Update: I have it working. See postscript at the bottom of this post. I am attempting to get the Arty Pmod VGA Demo running on a Digilent...

I made some updates to my 6502 system to get it ready for my FPGA VGA. Previously, my USB mouse took ten VIA pins (a bit of laziness on...

I am currently working on building an improved VGA circuit for my 6502 build. My goal is to offload the video processing and have better...

If you are looking to add the VGA Pmod to your Arty A7 and control output from MicroBlaze, the following are the steps I have taken to...

Continuing from my post FPGA VGA for 6502: Brainstorming... I am trying to find a decent solution to control VGA output from MicroBlaze....

I am currently brainstorming ways to add an FPGA-based VGA circuit to one of my 6502 builds. And... I have questions. :) As part of my...

I have added UART support to my VHDL 8-bit CPU, along with a Windows application that allows retrieving and setting RAM values at...

I am trying to determine why I am unable to communicate out through a UART on my Arty A7-100T. Any suggestions on how to troubleshoot...
