Code

• TinyPBC (download) (requires a compiled version of the RELIC 0.2.1 toolkit);

TinyPBC is mainly based on the RELIC Toolkit and targets the ATmega128L processor, the MICA2 and MICAz motes' processor. It is written in both NesC language, compatible with TinyOS, and C only so that it can be run in AVRStudio or Avrora simulators as well. The RELIC homepage has instructions on how to download the code as well as build TinyPBC.
