Squawk for Sun SPOT

Squawk for Sun SPOT

The aim of the Squawk for Sun SPOT project is to deploy the Squawk Java Virtual Machine on the wireless sensor and actuator Sun SPOT device developed at Sun Labs.  In this version of the Squawk JVM, the VM runs on the bare ARM-9 hardware and provides low-level operating system support, as well as application isolation (isolates).

The original port of Squawk to the ARM simulator was done by John Nolan in October 2004.  The port to run on the Atmel evaluation board and the Sun SPOT device was initially done by John Nolan, John Daniels, and Dave Cleal.
