Tyndall

Below is a summary of the Layers currently in use as part of the Tyndall Mote family of Mote Layers.

These have been predominantly developed for the National Access Program (NAP) and as such are in use throughout the country by researchers of various levels of expertise in the area of microcontroller use (ranging from expert Software programmers – typically in the computer science departments of research institutes to zero level expertise – say sensor researchers)

As such the programs/hardware/software are debugged prior to being released and should be considered as *mature* and tested on release.
