******************************************************************************
* -NOTE- The Win32 port is a simulation (or is that emulation?) only! Do not
* expect to get real time behaviour from the Win32 port or this demo
* application. It is provided as a convenient development and demonstration
* test bed only. This was tested using Windows 10 with Intel Core i7-6700 CPU.
*
* Windows will not be running the FreeRTOS simulator threads continuously, so
* the timing information has no meaningful units. See the documentation page for
* the Windows simulator for an explanation of the slow timing:
* http://www.freertos.org/FreeRTOS-Windows-Simulator-Emulator-for-Visual-Studio-and-Eclipse-MingW.html
* - READ THE WEB DOCUMENTATION FOR THIS PORT FOR MORE INFORMATION ON USING IT -
