The State of RISC-V Software

there is now tons of software for risc-v, enough to run a graphical linux desktop with some games and a web browser.

In their quest to democratize access to custom silicon, SiFive has announced the very first RISC-V-based Arduino just hours before the start of Maker Faire Bay Area 2017.

While details are a bit scarce at the moment, what we do know is that the aptly named “Arduino Cinque” features SiFive’s Freedom E310 SoC running at 320MHz along with an onboard ESP32 chip for 2.4GHz Wi-Fi and Bluetooth support.

“By partnering with a pioneer in open source hardware, SiFive can further advance the progress of open custom silicon among Makers, system designers and everyone else in between… We look forward to seeing the community’s reaction to the Arduino Cinque board, and believe that the Arduino concepts of openness and distribution mean that more people than ever will be exposed to RISC-V,” says Jack Kang, SiFive’s VP of Product & Business Development.
“Using an open source chip built on top of RISC-V is the natural evolution of open source hardware, and the Arduino Cinque has the ability to put powerful SiFive silicon into the hands of makers around the world,” adds Maker Media’s Dale Dougherty.

[not exactly hot news anymore, but Arduino annoncing a RISC-V board is just to cool to ignore.. i hope we hear more of this soon.]

Teensy SDR RX aka MetaSDR Project

Ich hatte die Idee super spannend gefunden mit dem Teensy3.2 und dem Audioshield einen ganz einfachen standalone SDR machen zu können. Ich hab jetzt zunächst mal nach YU1LM einen RX nachgebaut und er funktioniert ganz gut. Für den ersten Prototypen hab ich eine Platine gemacht und davon hab ich noch 9 Stück falls wer ihn nachbauen möchte. Damit kann man auch die Weiterentwicklung unterstützen :) Ich hab ihn MetaSDR getauft und wer möchte kann sich auch gerne sowohl an der Software- als auch an der Hardwareweiterentwicklung beteiligen. In der derzeitigen Software ist auch schon der TX Pfad enthalten. Mein Ziel ist es einen sehr kompakten QRP SDR Transceiver zu bauen. [...]  --Rainer, OE1KFR

Ronja is a free technology project for reliable optical data links with a current range of 1.4km and a communication speed of 10Mbps full duplex.

Applications of this wireless networking device include backbone of free, public, and community networks, individual and corporate Internet connectivity, and also home and building security. High reliability and availability linking is possible in combination with WiFi devices. The Twibright Ronja datalink can network neighbouring houses with cross-street ethernet access, solve the last mile problem for ISP’s, or provide a link layer for fast neighbourhood mesh networks.
