Welcome the DE0-Nano

My posting this summer, due to outside obligations, has been ridiculously sparse. (Literally 'outside obligations': I've been landscaping my yard all summer). I'm starting to have a little more idle time now that the summer is winding down, and now my motivation has been completely revitalized by this little guy: The DE0-Nano development board from Terasic. This little guy is exactly what I was [...]

SparkFun retires Cyclone II Breakout board

Usually, I would get a few people linking to Idle-Logic from SparkFun's Cyclone II Breakout board product page. Looking through the logs recently I noticed that this trickle of referrals dried up. I went to investigate only to find that the board has been discontinued... sad times. Down the road I plan on making my own breakout board, probably with the basic regulators and USB connections [...]

A Smathering of the Interesting

Unfortunately, I haven't had much Idle time lately for working on my nerd projects or blogging. In all my free time I'm outside tearing out trees and bushes and landscaping my yard. Not much Logic involved there, only destruction and mayhem. To get myself back into the blogging spirit, I decided to put together a series of posts sharing what content I'm absorbing these days. Let's [...]

Programming the Cyclone II using C++, libftdi and a FT2232H

Using a similar technique I covered in my last post, reader Bryan Richmond has been able to successfully program an Altera Cyclone II using C++, libftdi and a FT2232H USB/UART. From my understanding Bryan is running Debian on an ARM, and is programming the Cyclone II on his Morph-IC-II development board. I haven't had a chance to test the code, but Bryan has shown it to [...]

Programming an Altera Cyclone II FPGA with a FT232RL – Python Code

This is the final post in a series of three to explain how to use the FT232RL USB to UART Bridge to program a Cyclone II FPGA. The first part in the series describes how to compile and install the hardware drivers in Ubuntu that we need to use to access the FT232RL functions. The second part describes the hardware modifications and connections required to interface [...]

Programming an Altera Cyclone II FPGA with a FT232RL USB to UART Bridge

As I alluded to in a previous post, I've come up with a way to program my Altera Cyclone II FPGA with a $15 FT232RL USB to UART Bridge, avoiding the $300 investment in one of Altera's USB-Blaster cables. I'm going to break this tutorial up into three separate posts. The first has already been uploaded: libFTDI v0.18 with Ubuntu (Lucid Lynx), which describes how to [...]
