MicroEJ SDK support for NXP processors

MicroEJ® is a scalable solution to prototype, develop, and test software applications for embedded systems designed with NXP processors. The MicroEJ embedded platform concept drastically lowers costs of building applications, using modern software technologies inherited from the Java technology: Object Oriented Programming and Virtualization. It enables software developers to create portable and scalable applications, easy to maintain and reliable while keeping memory footprints and low power consumption. Typical markets include smart appliances, home and building automation, industrial control, healthcare, networking, smart energy and cities.

As a result of the strong collaboration between NXP and MicroEJ, MicroEJ SDK supports the FRDM-KL46Z, ARM Cortex-M0+, the Kinetis K70, ARM Cortex-M4, and the LPCXpresso54608, ARM Cortex-M4, MCUs. The MicroEJ solution is ready to be evaluated with these boards. MicroEJ includes everything required to start a HMI development on these boards and run a Java application in less than a few hours.
