The FreeMASTER serial driver is a piece of code that
enables an embedded application to communicate with
the FreeMASTER PC application. This application note
shows how to add the FreeMASTER serial driver to your
embedded code.
1 What are the FreeMASTER
serial driver and
FreeMASTER PC
application?
FreeMASTER is a PC-based development tool serving
as a real-time monitor, visualization tool, and graphical
control panel of embedded applications based on
Freescale Semiconductor processing units.
The FreeMASTER PC application repetitively sends a
request for the immediate values of chosen variables
used in the embedded application (the PC application
acts as the master in this peer-to-peer communication).
