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.
