Analog Input

• 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

• 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

• Keep it small

• We target micro-controllers, footprint matters

• Keep it focused

• There are a lot of Peripherals, Buses, Protocols, …

KEY CHALLENGES

• 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

COLLABORATION OPPORTUNITIES
