Hello again,

I've used successfully used ' read(fileno(fs), &value, 1) ' to block my C program until an interruption line is high.
But I have one more question: Can I use the gpio-event driver to write on a pin?
Or will I have to use something like ' system("echo 1 > /sys/class/gpio/gpio146/value") '
I think writing this way would be slower.
