ARM TechCon 2012: Software & System Design Schedule
ARM Technology Conference (TechCon) 2012 will take place on October 30 – November 1, 2011, in Santa Clara, and UBM Electronics has already posted the detailed schedule for the event. The first day (October 30) will be Chip Designs day and the other 2 days will focus on Software & System Design. Even if, like me, you are not be able to go there, it’s still interesting to know what will be discussed at the conference, to have a better idea where ARM is going, and what new technologies and/or development techniques are (or will become) available. There will be around 70 sessions categorized in 15 tracks: Android / Open Source – Development tools, middleware for native application development, and optimized drivers for Android, Linux, FreeRTOS etc … Compute Platforms – Development and implementation of standards and specifications, from board/module design to consumer and server designs Developing / Debugging – […]
Digi Launches XBee Modules Examples Website To Get Started with IoT Development
Digi International has launches an example section on their website to showcase what can be done with their XBee 805.15.4, ZigBee and WiFi Modules, as well as their IoT gateway. They provide examples to use different type of sensors, control lights, motors, and more. They show demos on the website and explain how each components can be linked together, hooked to computers and connected to the internet. They currently just have a few tutorials only, but plan to add more overtime: Basic XBee 802.15.4 & Zigbee Chat 802.15.4 PWM and Digital Output with an LED 802.15.4 Digital Input with a Button 802.15.4 Analog Input with a Potentiometer Light Switch XBee – A wireless wall switch that can control lamps, fans, motors or your homemade robot The first four examples look good to get started, but the Light Switch XBee is the most interesting, and they describe 8 steps to show […]
WiFi Tank Based on EEE PC, Arduino, Ubuntu and Node.js
Eight computer and electrical engineers built a WiFi Tank (Node.js robot) as part of a senior design project at Northeastern University, in Boston, Massachusetts. The robot brain is an EEE PC running Ubuntu, together with an Arduino board and is programmed using node.js. Each tank is equipped with a camera and 2 customized Wi-Fi repeaters (which it can drop it extend range), and it’s targeted at military operations or disaster-affected areas where network infrastructure is not available. Here are the key characteristics of this robot Robot controlled over WiFi 102 cm long, 71 cm wide, 41 cm tall, about 68 kg.
