A thesis on Arduino

April 18, 2011

I’m reading an interesting university thesis on Arduino, from Fabio Varesano’s blog, that I follow: My MoS Thesis: Using Arduino for Tangible Human Computer Interaction | Varesano.net. This thesis is a useful resource especially for people with a Computer Science background; it can generate many project ideas and arm any hobbyist with the tools to […]

Bus Blaster v2 JTAG debugger

April 17, 2011

Dangerous Prototypes recently announced the availability of the open source Bus Blaster v2 in their shop (here the announcement). The Bus Blaster is an USB tool to debug microcontrollers and embedded cores in general, and its design is completely open source. I already did a post on the first version of the Bus Blaster, but […]

ZPUino open source processor

March 6, 2011

ZPUino is a project that offers a microprocessor that can be put on FPGA, and that can be programmed with a simple IDE. Everything is open source: the toolchain, the IDE and the VHDL code; and it can be downloaded freely. The hardware architecture is based on the ZPU (Zylin CPU), which is a processor […]

Bus Blaster JTAG debugger

The Bus Blaster v1 is a prototype board (from Dangerous Prototypes) that allows to access the JTAG connection of integrated circuits through USB, using the FTDI FT2232H chip for the conversion. The prototype is on sale at around 35$ as they say on their page, but keep in mind that it is still a prototype, […]

Getting started with Arduino Uno on Ubuntu

January 31, 2011

I really wanted to try Arduino; Arduino narrates a story where the good guys are winning. Saturday I arranged to buy one, the Arduino Uno, and the first thing that came into my mind was “Wow, it’s really smaller than I thought possible!”. I went home and started unboxing it: the packages comes with a […]

The guys at OpenCores released a new version of their OpenRisc core, tweaking many hardware bug but also porting Linux kernel 2.6.24 to their simulation platform, that is called or1ksim. The procedure (found here) to try Linux on the new simulator is straightforward and involves executing a script. The script hides most of the complexity […]

New OpenRISC: academic work helps open source hardware

July 1, 2010
