Samsung JerryScript is a Lightweight Open Source JavaScript Engine for the Internet of Things

In the old days, micro-controller programming was all done in assembly or C, but in recent years higher level languages, included interpreted ones such as Python and JavaScript, have made their ways into MCUs with projects such as MicroPython or Espruino (JS) often running on STMicro STM32 ARM Cortex M micro-controllers, but also other platforms such as ESP8266. As I browsed through the Embedded Linux Conference Europe 2016 schedule, I discovered that Samsung worked on it own implementation of a JavaScript engine for the Internet of Things: JerryScript. It is a full implementation of ECMAScript 5.1 standard written in C that can run on micro-controllers with less than 64KB RAM, and less than 200KB storage (160KB footprint with ARM Thumb-2 compilation). JerryScript is comprised of two main components: Parser and Virtual Machine (VM), with the parser performing translation of input ECMAScript application into byte-code than is then executed by the Virtual […]

Embedded Linux Conference & IoT Summit Europe 2016 Schedule

Embedded Linux Conference & IoT summit 2016 first took place in the US in April, but the events are now also scheduled in Europe on October 11 – 13 in Berlin, Germany, and the schedule has now been published. Even if you are no going to attend, it’s always interesting to find out more about the topic covered in that type of events, so I had a look, and created my own virtual schedule with some of the sessions. Tuesday, October 11 10:40 – 11:30 – JerryScript: An Ultra-lightweight JavaScript Engine for the Internet of Things – Tilmann Scheller, Samsung Electronics JerryScript is a lightweight JavaScript engine designed to bring the success of JavaScript to small IoT devices like lamps, thermometers, switches and sensors. This class of devices tends to use resource-constrained microcontrollers which are too small to fit a large JavaScript engine like V8 or JavaScriptCore. JerryScript is heavily […]

96Boards Gets a TV Platform Edition Targeting $50 Mid-range Boards, $99 High-end Boards

96Boards was born as a hardware and software standard with Consumer (CE) & Enterprise Editions (EE), with different form factors with the latter focusing on server boards, but with similar software requirements requiring recent and mostly open source software. The consumer edition was also split into “Standard” and “Extended” editions, which the latter allowing for larger boards with more features, while the Enterprise Edition has its own larger format, as well as an option for micro-ATX form factor. I’ve just learned that a “fifth” 96Boards standard has been worked on with 96Board TV Platform for Home Gateways, OTT Streaming boxes, and TV boards with prices target of $50 or lower for mid-range boards, and $99 or lower for high-end boards. 96Boards TV Platform hardware requirements: Dimensions – 160 x 120 mm (EE Standard form factor) RAM – 1GB minimum; 2GB recommended Flash – 8GB eMMC minimum WiFi – 802.11 g/n […]
