This is a guide to the
timer C example project included in the EMAC OE SDK.
This project demonstrates how to use the software timer.
timer project builds one executable:
Opening, Building and Uploading the Project Files

Usage and Behavior
timer C example project will run just fine on any system for which it can be compiled.
timer program is executed from the console. It takes a single parameter.
Where frequency specifies the frequency of the timer's tick cycle.
It reports the delay between ticks, running until it is manually halted with a CTRL-C.
root@som9g20:/tmp# ./timer 1 Starting timer at 1 HZ delay : 1002 ms delay : 1000 ms delay : 1000 ms . . . delay : 1000 ms delay : 1000 ms ^C
Specifying 1 as our tick freqency, the timer cycles at a sedate 1000 ms (1 s) until we hit CTRL-C.
