Google Research PRUDAQ is a 40MSPS ADC Data Acquisition (DAQ) Cape for BeagleBone Black & Green

Engineers at Google Research wanted to measure the strength of a carrier signals without having to use a bulky oscilloscope or DAQ (Data Acquisition) system, so they looked into several makers boards to achieve this task, eventually decided to go with BeagleBone Black / Green, and created their own PRUDAQ cape capable of sampling 40 million samples per second, and open source it all. PRUDAQ cape specifications: Dual-channel simultaneously-sampled 10-bit ADC (Analog Devices AD9201) Up to 20MSPS per channel (40MSPS total) theoretical 0-2V input voltage range (DC coupled) 4:1 analog switches in front of each channel provide a total of 8 single-ended analog inputs. (See here for differential input) SMA jacks for direct access to the 2 ADC channels Flexible clock options: External input via SMA jack Internal on-board 10MHz oscillator Programmable clock from BeagleBone GPIO pins Powered via BeagleBone headers – no external power needed Fully exposed BeagleBone headers […]

SiFive Introduces Freedom U500 and E500 Open Source RISC-V SoCs

Open source used to be a software thing, with the hardware design being kept secret for fear of being copied, but companies such as Texas Instruments realized that from a silicon vendor perspective it would make perfect sense to release open source hardware designs with full schematics, Gerber files and SoM, to allow smaller companies and hobbyists, as well as the education market, normally not having the options to go through standard sales channels and the FAE (Field Application Engineer) support, to experiment with the platform and potentially come up with commercial products. That’s exactly what they did with the Beagleboard community, but there’s still an element that’s closed source, albeit documented: the processor itself. But this could change soon, as SiFive, a startup founded by the creators of the free and open RISC-V architecture, has announced two open source SoCs with Freedom U500 processor and Freedom E300 micro-controller. Freedom […]

AOMedia AV1 is a Royalty-free, Open Source Video Codec Aiming to Replace VP9 and Compete with H.265

The Alliance for Open Media, or AOMedia, is a new non-profit organization founded in 2015 by Amazon, Cisco, Google, Intel Corporation, Microsoft, Mozilla, and Netflix, and more recently joined by AMD, ARM, and NVIDIA, whose first project is to develop AV1 royalty-free and open video codec and format to provide an alternative to H.265 / HEVC, and a successor to VP9. The project is a team effort combining teams working on Daala, Thor, and VP10 video codecs, and while AFAIK, AV1 specifications have not been released yet (target: Q1 2017), the organization has already released an early implementation of AV1 video decoder and encoder under the combination of an BSD-2 clause license and the Alliance for Open Media Patent License 1.0 , which can be found on googlesource.com. So I’ve had a quick my myself following the instructions, by first downloading one uncompressed YUV4MPEG sample:

mkdir ~/derf_cif
pushd ~/derf_cif
wget http://media.xiph.org/video/derf/y4m/husky_cif.y4m
popd

mkdir ~/derf_cif

pushd ~/derf_cif

wget http://media.xiph.org/video/derf/y4m/husky_cif.y4m

popd

and the source code:

git clone https://aomedia.googlesource.com/aom
cd aom

1 2	git clone https://aomedia.googlesource.com/aom cd aom

Micrium µC/OS RTOS Is Now Free for Makers and Startups

According to UBM embedded market study for 2015, Micrium µC/OS real-time operating system only came second after FreeRTOS when the company asked close to 1,000 engineers and managers around the world which operating systems they were currently using in their embedded products. The OS appears to be particularly popular in Asia, and the results are all the more impressive considering it’s a commercial operating systems. But Micrium decided to bring more people on board by announcing a free version called µC/OS for Makers targeting hobbyists and startups (<$100k revenues) in February earlier this year. The real-time operating system includes a preemptive multitasking real-time kernel with optional round robin scheduling, has a low footprint (6K to 24K bytes code space, 1K+ bytes data space), support various types of targets including ARM Cortex-M and Cortex-A based MCU and processors such as STMicro STM32, NXP Kinetis, Cypress PSoC5, etc.., as well as Atmel […]

BusyBotNet is a Fork of Busybox with Security Tools

Busybox provides a lightweight version of common command line utilities normally found on “big” Linux into a single binary, in order to bring them to embedded systems with limited memory and storage. As more and more embedded systems are now connected to the Internet, or as they are called nowadays the Internet of Things nodes, adding security tools, such as cryptographic utilities, could prove useful for administrators of such system, and so BusyBotNet project wsa born out of a fork of Busybox. Some of the tools implemented include: fenc to encrypt stuff with salsa algo tsh. needs work, backdoor shell aes enc rathole backdoor shell, blowfish enc ssyn2 ddos tool sudp udp ddos tool jshon sh wrapper for json hydra prism userspace icmp triggered reverse shell backdoor You can access the source code and instructions on busyboxnet github repo. I’ve quickly tried it in my AMD x86 computer running Ubuntu […]
