•  Security, privacy, reliablity •  Remoteness, no human

control

•  Provisioning, management and monitoring

•  Data flow and analytics •  Interoperability and

standards

What keeps you awake at night?

•  Long device lifecycle •  Connectivity, cost,

infrastructure, bandwidth •  Device cost, power

requirements

•  Developer productivity •  Development cost, skill

sets, re-use •  Time-to-market

Example 2 Simple GPIO Pin-

On-Device I/O Peripheral Access

Device Access API

•  Generic API to access peripheral I/O in a platform-neutral manner

•  ‘Late binding’ allows addition of new peripheral types without changing API

•  Enables development of Java-based ‘device drivers’ (non-real time)

•  No native application code •  Also planned for

availability on Java SE

Access Peripheral I/O Hardware directly from Java applications


Demo: Lego Plane


GPIO Demo

GPIOPinConfig forward = new GPIOPinConfig(! 7, //Port Number! 3, //Pin number! GPIOPinConfig.DIR_OUTPUT_ONLY, //direction! PeripheralConfig.DEFAULT, //mode! GPIOPinConfig.TRIGGER_NONE, //trigger!! false); //initial value!! !GPIOPin forwardPin = ! (GPIOPin) PeripheralManager.open(forward);!!forwardPin.setValue(true);!
