EmbJPF 1 3 Prerequisites e PC with Windows XP or later e The STM32Java environment must be installed e STM32429I EVAL board e The ST LINK utility normally installed as part of the STM32Java installation 1 4 Terminology A Java platform JPF is a library that at a minimum embeds a JVM the MicroJvm virtual machine from IS2T some native libraries also called firmware or drivers or BSP and some Java libraries that characterize an application domain Depending on these libraries some specific tools are provided too Every embedded JPF EmbJPF has a sibling platform that simulates it on a PC called the SimJPF The SimJPF exactly mimics the semantics of the JPF The SimJPF can be extended with Mocks to simulate the native C Ada asm code of the JPF such as drivers or to connect hardware to the workstation Mocks can feed the SimJPF with real external stimuli so that the Java application can behave as if it was running on the EmbJPF SimJPF allows the design and functional testing of an embedded Java application in a development environment STM32Java provides a kickstart Java Platform Guide that ease starting with Java on a dedicated micro controller Directly out of the box one can write Java code without needing to write any low level code such as code to port the JPF to specific hardware The supplied kickstart JPF uses the STM32429I EVAL board from which most peripherals are accessible including displ
