Front Panel API

Since MicroEJ UI Pack 13.0.0, the Front Panel project must depend on module com.microej.pack.ui.ui-pack(frontpanel). The module version is the MicroEJ Generic UI Pack version, that is always aligned with the MicroEJ UI Packs specific for MCUs.

UI Pack Range Module Version
[13.0.0-13.0.6] com.microej.pack.ui.ui-pack(frontpanel) UI Pack version
[12.0.0-12.1.5] ej.tool.frontpanel.widget-microui 1.0.0

Note

Before MicroEJ UI Pack 12.0.0, the Front Panel project must depend on classpath variable FRONTPANEL_WIDGETS_HOME.

Image Generator API

Since MicroEJ UI Pack 13.0.0, the Image Generator extension project must depend on module com.microej.pack.ui.ui-pack(imagegenerator). The module version is the MicroEJ Generic UI Pack version, that is always aligned with the MicroEJ UI Packs specific for MCUs.

UI Pack Range Module Version
[13.0.0-13.0.6] com.microej.pack.ui.ui-pack(imagegenerator) UI Pack version
