wiringPi Examples
=================

There are now too many examples to compile them all in a sensible time,
and you probably don't want to compile or run them all anyway, so they
have been separated out.

To compile an individual example, just type

    make exampleName

Where exampleName is one of:

    test1 test2 speed lcd wfi isr piface gertboard nes pwm tone servo
    delayTest serialRead serialTest okLed


All Done.
