Supporting 200 Different Expansions Boards: The Broken Promise of Device Tree – ELCE 2012

Koen Kooi, software engineering manager at Circuitco Electronics and lead developer of the Angstrom distribution, explains that device tree does help with the ARM Linux kernel, but brings all the complexity to the bootloader(s), taking the variety of Beaglebone capes as example, at the Embedded Linux Conference in Barcelona, Spain, on November 6, 2012. Abstract: Devicetree is marketed as the one ring to rule them all when it comes to non-discoverable hardware for Linux on ARM. The problem with devicetree is that the complexity gets removed from the kernel and put into the bootloader. Koen first gives an overview of device tree, and provides an example (am33xx.dtsi) to show device tree data structure. Then time for some Beaglebone and capes promotion overview,  before moving to the core of the problem: Pinctrl Resource tracking EVM/bone split uboot/uimage/dtb lockstep pdata only Keycodes and other non-hardware bits You can also download the presentation […]

Beaglebone: The Perfect Telemetry Platform? – ELCE 2012

Matt Ranostay, technical staff at Ranostay Industries, gives a presentation about a telemetry system based on Beaglebone at the Embedded Linux Conference Europe on November 5, 2012. Abstract: The author will discuss his ongoing and other team members efforts to develop hardware and software that reports sensor data to the community. This talk will be split into several parts a) types of useful sensors b) hardware design of Beaglebone capes c) and telemetry reports to Pachube/Cosm. Demonstrating that in the new world of cheap prototyping boards with I2C, GPIO, and SPI that anyone can setup a decent monitoring system for home security, automation, and weather reporting. There will be a live demo of prototype geiger counter + weather station. The audience targeted is the professional hobbyist who likes to hack on microcontrollers in their spare time. It will take little to medium knowledge of electrical engineering to follow this talk. […]

Wireless Networking with IEEE 802.15.4 and 6LoWPAN – ELCE 2012

Alan Ott, founder of Signal 11 Software, gives a presentation dealing with wireless networking for the internet of things in Linux, especially with 802.15.4 and 6LoWPAN standards at the Embedded Linux Conference in Barcelona, Spain on November 5, 2012. Abstract: With the rise of the internet of things, low-power wireless devices will become increasingly prevalent. IEEE 802.15.4 is a wireless networking protocol designed for low-power and low-data-rate devices, such as those used in wireless sensor networks. While some higher layer protocols based on 802.15.4 are proprietary, an open standard called 6LoWPAN enables IPv6 traffic over 802.15.4. This presentation will give overviews of 802.15.4, its status in the Linux kernel, hardware support, comparison with other wireless protocols, and a demonstration of a simple 802.15.4/6loWPAN network. This presentation is targeted toward developers who wish to create low-power, low-data-rate wireless networks for sensors or other applications. Attendees can expect to gain a basic […]

Android Cortex A8 Keyboard / Advanced Remote for TV

Remote Solution,  a small technology company based in Hong Kong South Korea, has shown off an Android 4.0 powered keyboard controlling an Android STB at CES 2013. The device is designed to be used as an advanced TV remote control, looks like a small tablet with 8 control button, and can be inserted into a full sized QWERTY keyboard for faster typing. The specifications are as follows: SoC – ARM Cortex-A8 processor @ 720 MHz (I’d guess a TI OMAP3 or Sitara processor at this freq) System Memory – 512MB RAM Storage – 2GB flash Display – 3.5″ touchscreen display (480 x 320) Connectivity – WiFi and Bluetooth Misc – IR port to be used as a universal remote. The touchscreen allows you to launch apps on your TV, move a cursor by using a virtual touch-pad, use an on-screen keyboard (when the screen is not connected to the keyboard), […]
