[avr-chat] The Protothreads library version 1.3

[Adam Dunkels]

Dear all,

the Protothreads library version 1.3 is out:

                   http://www.sics.se/~adam/pt/

Protothreads are extremely lightweight, stackless threads designed for
severely memory constrained systems such as small embedded systems or
sensor network nodes. Protothreads provide linear code execution for
event-driven systems implemented in C. Protothreads can be used with
or without an underlying operating system.

Protothreads provide a blocking context on top of an event-driven
system, without the overhead of per-thread stacks. The purpose of
protothreads is to implement sequential flow of control without
complex state machines or full multi-threading. Protothreads provide
conditional blocking inside C functions.

Main features:

    * No machine specific code - the protothreads library is pure C
    * Very small RAM overhead - only two bytes per protothread
    * Can be used with or without an OS
    * Provides blocking wait without full multi-threading or
      stack-switching
    * Freely available under a BSD-like open source license

Best regards,

/adam
