EclipseCON Europe 2016 8

• Not much to say

• We silently droppped a first release end of July, mostly for legal evaluation

• Communication activity re-started end of September, with a Virtual Meetup

• Expect more soon… as we finally got the legal approval last Friday

PROJECT STATS

Oct 24th 2016

EclipseCON Europe 2016 9

• Second code drop to happen this week• Significant set of changes• Includes a MicroEJ-specific implementation• Runs on a STM32F746G-DISCO board (Cortex M7)• Defines the base framework

• Next releases should happen soon• Device API definitions (e.g. SPI, I2C, CAN)• Topology-related improvements• More ports (MicroEJ targets, and other runtimes)• More samples

• Next MicroEJ OS releases will be based on Edje

PROJECT PLAN

Oct 24th 2016

EclipseCON Europe 2016 10

• Keep it small• We target micro-controllers, footprint matters

• Keep it focused• There are a lot of Peripherals, Buses, Protocols, …

KEY CHALLENGES

Oct 24th 2016

EclipseCON Europe 2016 11

• For new Peripheral API definitions• Get input from field experts

• For new ports• Raspberry Pi / JavaSE / jdk.dio, anyone ?

• Demos• If you have a gateway or cloud project and need devices, think

Edje !• We can have Edje on any MicroEJ target• Come see us on the Playground, and you’ll see:

• Edje• LWM2M (Leshan)• Californium• Eclipse IDE
