AllWinner A10s Processor Overview

Between the AllWinner A10 and AllWinner A13 processors, there’s now an alternative. AllWinner A10s is based on AllWinner A13 architecture (sun5i), but adds HDMI and Ethernet MAC which makes it suitable for mini PCs and set-top boxes. The first time I heard about this processor was in August with IP878 mini PC, and in October, one reader (Alex) informed me AllWinner had posted more details about his new processor. Here are the key features of this (relatively) new SoC: CPU/GPU – ARM Cortex-A8 Core with 32KB D-Cache/ 32KB I-Cache / 256KB L2 Cache, and Mali-400 VPU HD Video Decoding 1080p@30fps of VP8/6, H.264/H.263, WMV9/VC-1, WMV7/8, MPEG-4/2/1, Xvid codecs HD Video Encoding 1080p@30fps with H.264 codec Video Out – HDMI 1.4 (1080p), Memory Up to 1GB DDR2/DDR3 up to 533MHz (16/32 bits Data Bus) MLC/TLC/SLC/EF-NAND ECC 64-bit Peripherals: USB2.0 OTG, USB2.0 HOST （OHCI/EHCI） SD Card V.3.0, eMMC V.4.2 SPI, TWI and […]

Kimdecent T21 mini PC Unboxing and Review

Androidpc.es has written a review for the low cost ($49) Kimdecent T21 dual core mini PC in Spanish, and I’ll provide a summary of the review in English below. Kimdecent T21 Unboxing Kimdecent T21 is an Android 4.1 HDMI TV Stick powered by Nufront NS115 dual core Cortex A9 processor. Check out my earlier post about Kimdecent T21 for specifications. The package comes with T21 mini PC, a power adapter with USB to micro USB cable, and a user manual in English. You can also watch  T21 Unboxing Video on YouTube. Kimdecent T21 User Interface & System Overview The user interface is a standard Android screen, albeit with power and volume buttons in the Status Bar. I don’t really find this interface very suitable for the TV, but you can always install your own launcher such as Android TV Launcher (apk), or other launcher apps available on Google Play.

SoC Power Measurement with ARM Energy Probes and Linux EAP Tools

Andy Green, TI Landing Team lead at Linaro,  gave an interesting presentation entitled “How to measure SoC power” at Linaro Connect Europe 2012. This talk was specifically aimed at software engineers, so that they know how to properly measure power consumption, and take actions to optimize the software to decrease it. In the first part of the presentation, he gives an overview of electronics basics with definition of voltage, load, current and power, units used for power measurements (Clue: you need to use Watts), and how voltage, current and power can be measured with voltmeters and ammeters. When you want to measure power in a rail, you would usually insert a shun resistor, use a multimeter and derive the power from the resistance and the measured voltage (P=V2/R). He also gives details about regulator efficiency, choosing measurement sampling… There are 4 common measurements strategies: DC IN – Easiest way, gives the complete […]

Xibo for Android on Mele A1000 Set-top Box & WM8850-MID Tablet

Earlier this month, Xibo developers announced the beta version Xibo for Android was available for testing. Contrary to the Linux & Windows clients and servers which are open source, Xibo for Android is developed by Spring Signage and will available commercially. This sponsorship will help finance the development of Xibo open source software: the 2 clients (.net in Windows, Python in Linux), the server and API. The current beta version supports the most important features of the Windows client, but lacks support for Adobe Flash, Microsoft PowerPoint, Datasets, Microblog, Stats, Counter Media, Socket Listener, Lift/Serial Interface Support, Offline Update via USB Drive, Full Compositing (overlapping regions) and Video Transparency. If you want to test the Xibo client for android, you can register for the private BETA and download an APK (Xibo_Android_Clientv1.0.12.apk) to install on your Android devices. Being part of the BETA program will also guarantee you a price of […]

Le Labo Citoyen Gasser – Raspberry Pi Based High Precision Pollution Monitoring System

“Le Labo Citoyen” is a recently founded French non-profit organization aimed at “promoting and experimenting with innovating and free technologies for the citizens and the environment”.  Their first project is to gather pollution data (NO2, O3, and SO2 levels) in Paris using 2 (soon to be) open source components: Gasser – Self-contained mobile sensor currently powered by the Raspberry Pi ThingStream – Open source IoT datastore which should be similar to iDigi Cloud, except you can just store data in your own server or on “Le Labo Citoyen” servers. Gasser has four main parts: Sensor(s) – Alphasense B4-series sensors (black and red component in the top left of the  main box) with accuracy of up to <10 ppb (parts-per-billion). Cost: ~110 Euros. They currently only use the NO2 (nitrogen dioxide) sensor. ADC & Computer – Raspberry Pi (Cost: ~30 Euros) & Delta-Sigma ADC (Cost: ~30 Euros). Communication Medium – Huawei […]
