simple.java

用于传感器网络的节点操作系统 TinyOS 结构设计非常有意思

/* Simple mig test, designed to run with the apps/TestMig1 app on a mote
   just prints the messages received from TestMig1 via GenericBase and
   a SerialForwarder.
   The SerialForwarder is assumed to run locally on port 9000.
   The group id is specified on the command line

   Note: this code breaks (on linux at least) without the 'extends JPanel'
   bit. Don't ask me why (errors mention mprotect...).

   See Send for an example which also sends a message
