Online Getting Started¶
The MicroEJ Multi-Sandbox Firmware Getting Started is available on MicroEJ GitHub repository, at https://github.com/MicroEJ/Example-MinimalMultiAppFirmware.
README.md provides a step by step guide to produce a
minimal firmware on an evaluation board on which new applications can be
dynamically deployed through a serial or a TCP/IP connection.
MicroEJ Demo VEE Flavors¶
This set of APIs is proposed as examples of industrial or commercial typical products APIs.
What is a MicroEJ Demo Runtime Environment?¶
A MicroEJ Runtime Environment defines a set of MicroEJ APIs exposed to a MicroEJ Sandboxed Application. Here are the default runtimes provided for evaluation by MicroEJ. Any runtime can be customized with MicroEJ SDK for a specific product.
|MicroEJ Demo Runtime Environment||EDC/B-ON/KF||COMP/WADAPPS||MICROUI/MWT||LEDS/BUTTONS||NET/CONNECT/SSL||BLE||HAL||ECOM/COMM|
You can find below what are the different APIs included in the Runtime Environment:
|EDC||Core APIs for the execution.|
|B-ON||Memory Usage control and Sequences start-up.|
|KF||Required by the implementation of Shared Interfaces, an inter-application communication process.|
|COMP or COMPONENTS||Lightweight Services Framework.|
|WADAPPS||Wadapps Application Framework.|
|MICROUI/MWT||Main UI library for MicroEJ and the Widgets framework based on MicroUI.|
|LEDS or MICROUI-LEDS||UI library specific to LEDs.|
|BUTTONS or MICROUI-BUTTONS||UI library specfic to buttons.|
|NET||Socket (TCP/UDP) library.|
|CONNECT or CONNECTIVITY||Network connectivity detection library.|
|SSL||Secure Socket Layer.|
|BLE||Bluetooth Low Energy support.|
|HAL||GPIO Access (digital and analog)|
|ECOM||Device access framework.|
|COMM or ECOM-COMM||Serial ports support for the ECOM.|
What is a MicroEJ Demo Flavor?¶
A MicroEJ Demo Flavor is a composition of a set of runtime services, System Applications and a given MicroEJ Runtime Environment. Any flavor can be customized with MicroEJ SDK for a specific product.
You can find below what are the different System Apps included in the Flavor:
|Management||Contains the implementation of Wadapps framework services, required by all VEE.|
|App-Metadata-Storage||Stores some Applications Metadata (icons, descriptions) so that it can be locally used by a MicroEJ Companion.|
|CommandServer-Socket||Allows the deployment of MicroEJ Applications through a local network connection.|
|NTP||Synchronizes the time of the device.|
|About||Displays version information about the VEE.|
|AppList||An application browser, can be used to start, stop or uninstall the applications, or display their descriptions and version information.|
|Forge Connect||Displays a desktop that allows the management of MicroEJ Applications using a connection to MICROEJ FORGE.|
|Settings||Displays the VEE parameters and settings.|
