Talking to the DE0-Nano using the Virtual JTAG interface.

How to communicate between a PC and a design running on the DE0-Nano using the Virtual JTAG Megafunction, a Tcl TCP/IP Server running in quartus_stp with virtually any programming language. The first thing I wondered when I got my hands on the DE0-Nano was how best to communicate with a design inside the FPGA. Initially, [ READ MORE ]

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 [ READ MORE ]

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 [ READ MORE ]

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 [ READ MORE ]

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 [ READ MORE ]
