Running the Application

The 04-synchtemp sample application showcases the network-wide synchronization of a 

Include Page
_def_smip _def_smip

 network allowing you to capture temperature measurements across a network synchronized to within a few milliseconds.   It works in concert with the SyncTemp command-line application (part of the SmartMesh SDK), which logs the data.  The SynchTemp directory also includes logAnalysis.py, which will calculate some statistics about the temperature data timing.

Info
While nodes in a Include Page _def_smip _def_smip network as synchronized to within a handful of micro-seconds, the precision of the uC/OS-II timers limits the accuracy of the temperature measurement synchronization to a handful of milliseconds.

Implementation Details

The sample application consists of a task which arms a timer, waits for it to expire, then takes a temperature measurement and sends it to the manager.
