This video shows an embedded Java application developped with the MicroEJ SDK, running on a STmicroelectronics STM32F439-EVAL board (ARM Cortex-M4 @168MHz), and highlighting the MicroEJ UI framework with transparency management, based on the STM32 Chrom’ART hardware. 4 active layers are visible, with their own transparency and their own movement: the IS2T logo, the ST logo, the background image with a parallax effect, the CPU text label. All layers are rendered with less than 5% CPU load (displayed at the bottom left of the screen).
