Re: [oopic] Re: events again

BLINK_code is supposed to be an *event handler* that does something
fast and gets out, not a piece of code that takes its sweet time
doing whatever it feels like.

If you want to play around with event handling, do something fast,
like toggle the LED's state (LED = 1 - LED)
