LiveCode + Raspberry Pi - Light up a LED

Recently I bought a Raspberry Pi.

And I noticed that LiveCode has a RPi version installer on the download page.

so, I install LiveCode on my Rasberry Pi.

Write an external on LiveCode with C to control the GPIO.

Finally I can use a simple LiveCode Script to light the LED.

And event blinking an LED.

Here's what I wrote in LiveCode script

    haogpiosetup()

    repeat with x = 1 to 10

        put haogpiowrite(4,true)

        wait 1 sec

        put haogpiowrite(4,false)

        wait 1 sec

    end repeat

I use function instead of command just in case that I can be sure whether my external code are wrong.

If everything go well, my function will return "OK" 

I'll post my work here constantly.
