Charbax is now at the China Sourcing Fair in Hong Kong, meeting and interviewing lots of Chinese companies. One of the companies I’ve been following is AllWinner because of their low-cost ARM Cortex processors, found in many Android devices, which somewhat support Linux. In the video below, we first learn they have shipped 1 million A31 in the last 4 months, A31s and A20 processors have been available since the end of March for phablets, and A20 price is supposed to be very close to A10. So products based on AllWinner A10 could be upgraded to AllWinner A20 for just a few dollars more as both SoC are (nearly) pin to pin compatible. By the way, if you’re interested in the Cubieboard, you may want to see this. We then go through lots of devices based on AllWinner SoC, albeit too fast to get many details, but the list may […]
Keil RTX RTOS is Now Available for Energy Micro EFM32 MCUs
Energy Micro has recently announced the availability of the Keil RTX real-time operating system (RTOS) as part of its Simplicity Studio tool suite. The Keil RTX has been optimized for ARM Cortex-M processors to provide flexible scheduling and high-speed operation, and has been improved to enable an ultra-low power, deep-sleep mode between tasks. Energy Micro has implemented a tickless mode in Keil RTX. This mode allows the EFM32 Cortex M3 MCUs to wake up only when needed, either at a scheduled time or on an interrupt event. This results in much lower power consumption in sleep mode compared to other SysTick implementations. The video below shows the difference between SYSTICK mode where the system consumes about 2.7mA in active mode, and 830 uA in sleep mode to the new tickless mode where the MCU still consume the same amount of energy in Active mode, but only 1uA in sleep mode, […]
UDOO Single Board Computer Features Freescale i.MX6 Dual/Quad and Atmel SAM3 MCU

Open Source Time Machine #2 – Build A Complete Watch Yourself
There are already some watches such as Texas Instruments ez430-Crhonos and MetaWatch that are used as development platform and let you develop software yourself. Some hardware documentation is usually provided as well, but Energy Micro forums’ member hairykiwi is trying to go a bit further. He created a watch based on EFM32 Cortex M3 MCU and already released the KiCad schematics and gerber files, with 3D printer files and firmware source code to be released once they are ready. The project is called “Open source Time Machine #2” (OTM2). The project makes use of the following components and features: EFM32LG332F256 – Energy Micro Cortex M3 Leopard Gecko MCU with 256KB flash and 32KB SRAM A 128×128 pixel (23.2 x23.2mm visible area) ultra low power Memory LCD from Sharp Microelectronics, Recharge and programming via Micro USB connector. JTAG programming is also available. 150mAh Li-Po Battery + on-board battery fuel gauge IC. […]
$55 AX-14 DLNA, WiDi & Miracast Dongle Works with Android / iOS Devices, and Windows 7/8 PC
Miracast is a new standard allowing you to play videos or mirror your Android device display on a TV via Wi-Fi direct. All you need is a Wi-Fi device that can be connected to the HDMI and USB (for power) ports of your TV, and decode common video codecs. There are not many devices available on the market, but I’ve just found out about AX-14, a Wi-Di and Miracast HDMI adapter that lets you connect your Windows 7 or 8 to your TV via Wi-Di, or your Android / iOS via Miracast. The device also supports DLNA. The hardware specs are said to be as follows: Processor – MIPS24Kc processor (RTD1185PA) @ 500MHz System Memory – 256 MB DDR3 SDRAM Storage – 128 MB NAND Flash Video and Audio engine with HW acceleration Video Codecs & Formats – MPEG-1,MPEG-2,MPEG-4 SP/ASP( Xvid), MPEG-4 AVC(H.264), AVS, VP6, Motion JPEG, H.263 , H.264, […]
CloudnetGo CR9 RK3188 mini PC Review
The folks at AndroidPC.es have received a preliminary sample of CloudnetGo CR9 HDMI TV dongle powered by Rockchrip RK3188 quad core processor with 2GB RAM and 8GB flash, and posted an unboxing video and a review of the device. That’s the first review of a RK3188 mini PC I’ve ever seen. It’s in Spanish, so let’s provide a summary of their findings in English. Please note that it’s an early sample, so minor hardware changes may occur, and Android 4.1 will be upgraded to 4.2 once it ships later this month. CloudnetGO CR9 Unboxing The package contains the device itself, a 5V/2Apower supply, an extra short HDMI cable, a micro USB to USB cable, a micro USB to USB adapter and a user manual. If you prefer unboxing videos, they uploaded one with background music, no commentary. First Boot and First Impressions Let’s connect the device to the TV HDMI […]
Preliminary Ubuntu 12.04 RootFS for GK802/HI802 mini PC
After releasing a pretty good Ubuntu 11.10 image with both VPU and GPU acceleration for Freescale i.MX6 based HDMI dongles last month, Jasbir (aka jas-hacks) has released an Ubuntu 12.04 image with GPU support thanks to the help of Octavio (Yocto Project contributor), and Wi-Fi support. It’s possible to select Unity 2D or Xubuntu desktop, and Chromium and Neverball, a 3D ball game, are part of the image. There’s still more work however, as VPU (Video Processing Unit) support is work in progress, Bluetooth does not work yet, and OpenGL ES test programs such as glmark2-es2 or es2gears do not work properly with Xubuntu, even though they do work fine with Unity 2D. Jasbir uploaded a video showing Neverball 3D game in GK802, and it works pretty good, although the framerate does not seem optimal for now. If you want to give this image a try, install GK802 Ubuntu 11.10 […]
Veidoo HD2 Android Set-top Box Features a 5MP Camera
There seem to be more and more Android set-top boxes that can be fitted on top of the TV, but if you are mainly interested in video conference they may not always have very good cameras: MK818 comes with a 0.3MP camera and Archos TV Connect has a 1MP webcam according to Arctablet, which is good enough for 720p video conferencing. On the contrary, Veidoo HD2, an Android 4.0 set-top box powered by AllWinner A10, comes with a 5MP camera which should allow you, in theory, to do video conference in 1080p if your internet connection permits it. Here are the specifications of the device: SoC – Allwinner A10 Cortex A8 @ 1GHz + Mali-400 GPU Memory – 1GB RAM Storage – 8GB + micro SD slot (Up to 32GB) Connectivity – Wi-Fi 802.11b/g/n + 3G support via external 3G dongle Camera – 5.0MP auto focus Video Output – HDMI […]
