 // This a test of [Andrew L] mbos
 // main.c copied from  mbos.h comments
 // ** A 3d task added **
 
 
 //* A typical simple example with two tasks, and one timer, might look like this:
 //* @code
 // mbos Blinky demonstration.
 // Task 1 toggles LED1 every second, under control of a timer. It then posts an event to
 // task 2 which flashed LED2 briefly.
