Variscite DART-4460 SoM is Small, Very Small, and Powered by TI OMAP4460

Variscite announced DART-4460, a new system-on-module based on Texas Instruments OMAP4460, with up to 1GB LPDDR2 RAM and 8GB eMMC flash. The key differentiating point of this module is its size (17 mm x 52 mm), which could make it the world smallest dual core module, although Logic PD’s DM3730 / AM3730 Torpedo SOM might be the smallest of all in single core configuration. DART-4460 system-on-module specifications: SoC – Texas Instruments OMAP4460 dual core cortex A9 @ 1.5 GHz max + PowerVR SGX540 GPU System Memory – 512 to 1024 MB LP-DDR2 Storage – Up to 8 GB eMMC + 2x SD / MMC Video – 1080p30 H.264 Encode / Decode Camera Interfaces – 2x CSI, 1x CPI Display HDMI 1.3a 1920 x 1080 24-bit RGB 1400 x 1050 24-bit DSI 1400 x 1050 4-wire resistive touch Connectivity Wi-Fi 802.11 b/g/n Bluetooth 4.0 Audio – Headphone, digital microphone, S/PDIF, Line […]

Souliss Automation and IoT Framework Makes Your Home Smarter

Souliss is an open-source framework written in C/C++ for the Internet of Things and home automation that runs on Arduino boards, or other Atmel AVR MCU based boards, and let your control lighting, heating, or anything else you can think of via your Android device, or switches connected to your board(s). You can get started with Souliss in 3 steps: Getting the building blocks, for example: Arduino, Olimex, or other AVR boards (See list of supported boards) Relay boards ON/OFF Switches, Lights, etc… Wi-Fi router Download and load Souliss to an AVR powered board controlling real things such as lights. Monitor and/or control via Souliss Home Automation App for Android. A detailed getting started guide is provided on Souliss Google Code page. Internally, the framework is composed of three parts: Souliss, an application level layer, MaCaco, a communication protocol and vNet, a transport layer. I’ll skip details in this post, […]

Measy U4K – AllWinner A31 Powered Mini PC for 4K2K Video Playback

Apart from CS868, I had not seen other HDMI TV sticks based on AllWinner A31, the main reason being the performance to price ratio, with RK3188 devices cheaper than AllWinner A31 ones, and benchmarks such as Antutu showing better score for RK3188. 2D/3D performance is about the same as RK3188 (based on Antutu benchmark), despite A31’s PowerVR SGX544 MP2 GPU. So the only remaining advantage of A31 over RK3188 is 4K2K (UHD) video playback, which is probably why Measy called their A31 mini PC “Measy U4K”. Measy U4K Specifications: SoC –  Allwinner A31 quad-core cortex A7 @ 1.0GHz + PowerVR SGX544MP2 GPU System Memory – 2GB dual channel 64-bit DDR3 Storage – 8GB Nand dual channel 16-bit Flash + micro SD card slot (Up to 32 GB) Connectivity – Wi-Fi 802.11 b/g/n (Ralink8188) + Bluetooth 4.0 USB – 1x micro USB OTG for power, and 1x USB 2.0 host Video Output […]

Rockchip RK3188 Linux Source Code is Now Available

Good news! I’ve just read Rockchip RK3188 Linux source code has just been released via Rikomagic, and Alok Sinha, the main maintainer of RK3066 source code, has already imported into github, and we should soon see a PicUntu image for RK3188 mini PCs. Let’s have a look:

[Update: you may have to run “sudo apt-get install libc6-i386” before running make_kernel_ruikemei.sh below, as mkkrnlimg is a 32-bit binary] Usually, I immediately look into arch/arm/configs, but this time, there’s a “funny” script called make_kernel_ruikemei.sh, and .config already have some CONFIG_RK3188, so let’s run it:

After just over a minute, success!:

This kernel image is for Android only, and there’s a little work to modify it as a “pure” Linux kernel, so that it can be used to boot PicUnutu for RK3188. Let’s go back to arch/arm/configs, and we’ll find several RK3188 configs: rk3168_86v_defconfig rk3188_dongle_defconfig rk3188_ds1006h_defconfig rk3188_ds1006h_v1_0_defconfig rk3188_hotdog_defconfig rk3188_LR097_defconfig rk3188_magicwand_defconfig […]

Bluetooth Versions Walkthrough, and Bluetooth 4.0 Low Energy Development Resources

I’ve seen more and more Bluetooth 4.0 LE devices in the last few months including RFDuino, Wimoto Motes, TI SensorTag, and Scadanu Scout, so I thought it would be good to write a bit about Bluetooth. First, I’ll write about the different version of Bluetooth, since I was still confused with the practical implications between the versions, and then I’ll show some development kits and software resources to play around and/or develop Bluetooth 4.0 LE applications both on devices and hosts. Bluetooth Versions Bluetooth v1.0 and v1.0B The Bluetooth 1.0 Specification was released in 1999, and according to an entry in Wikipedia, 1.0 and 1.0B devices had many issues, mainly interoperability issues. You won’t find any Bluetooth 1.0 device today. Bluetooth v1.1 Bluetooth v1.1 was ratified as IEEE Standard 802.15.1-2002 in 2002. It fixed many issues found in the previous specifications, added the option to use non-encrypted channels, as well […]

Scanadu Scout Medical Tricorder for Android and iOS

Low cost personal medical tricorders have the potential to dramatically bring down the cost of health care, and avoid unnecessarily wasted time in hospitals, which is probably the XPRIZE Foundation has launched a competition for  medical tricorders, where the winners will get 10 millions US dollars in funding. Scanadu Scout is one of the entry, and they currently have an indiegogo campaign, already oversubscribed, for their medical grade tricorder which gather data by placing it on your forehead for 10 seconds, and display medical data transferred via Bluetopoth Low Energy (Bluetooth SMART) on your iOS and smartphone. The company did not disclose full specifications, but they still revealed the device runs 32-bit Micrium RTOS, which is already FDA approved (pre-market 510K notification and PMA approval), it supports Bluetooth 4.0 SMART, and a micro USB port is included to recharge the battery. I fired up few Google image searches to look […]
