Bringing Java to the world of microcontrollers

C is a beautiful language perfectly suited for development on low-power devices such as the 8-bit microcontrollers. With newer, more powerful ARM microcontrollers making their way onto the market and workbenches around the world, it was only fitting that Oracle got in on the action. They released a version of Java targeted at these newer, more powerful microcontrollers called Java ME embedded.

The new embedded version of Java has everything you would expect from a microcontroller development platform – access to GPIO pins, including SD cards and I2C devices. The new Java machine is designed for full headless operation and is capable of running on devices with as little as 130 kB of RAM and 350 kB of ROM.

As for the utility of programming a microcontroller in Java, it’s still the second most popular language, after spending the better part of a decade as the number one language programmers choose to use. The requirements of the new embedded version of Java are far too large to fit onto even the best 8-bit microcontrollers, but with a new crop of more powerful ARM devices, we’ll expect to see more and more ARM/Java projects making their way into the Hackaday tip line in the coming months.

Tip ‘o the hat to [roger] for sending this one in.
