SAN FRANCISCO: ENTERPRISE VENDOR Oracle demonstrated Java SE for embedded devices running on the Raspberry Pi bare bones computer at the Java One show on Wednesday, with the aim of encouraging developers to try it out for themselves to create reference libraries for the target school children audience.
Simon Ritter, technology evangelist at Oracle, showed a packed room of developers attending the Java event in San Francisco how he had programmed the Raspberry Pi to get sound and video. He also gave a step by step guide to how he used the Raspberry Pi running Java to hook up a games controller, which could then control a robotic arm.
Ritter said that while his demonstration and experiments required fairly in-depth technical understanding, the end goal was to engage younger computer users.
He said the idea behind the machine is for kids to use a basic language like Scratch, for example, to learn programming, and build up skills via Greenfoot, before gaining enough experience to move onto Java IDEs Bluej or Netbeans.
"What I'm talking about is mostly a hobbyist thing, but if we can get these libraries published, the more advanced student can also use these to control a gamepad with the Raspberry Pi," Ritter said.
Ritter, a Brit who worked for Sun for 14 years before it was acquired by Oracle, also used his presentation to highlight the move by Raspberry Pi to transfer production to the UK.
"One of the nice things from my perspective is that they've actually shifted production away from China and they're now doing production in the UK," he said.
"Sony has a factory in Wales and they're now producing the boards for the Raspberry Pi foundation, so it's nice from a UK perspective."
Raspberry Pi owners are also now being offered support if they want to overclock their boards. Ritter told the audience that the organisation will now honour the warranty for overclocking up to 1Ghz.
"There are people who've overclocked them to 1.2Ghz, but they run into problems with memory access and it becomes very unstable," he said.
We've got video of the Raspberry Pi demonstrations from Java One, so check back at The INQUIRER later this week to see those. µ
