Good work! I will compare my configuration to this.


Actually, after my LED is blinking, i try to query inputs.
I cannot figure out how to assign the port from an output to an input and
how to read the input state.

outr(PIO_OER, _BV(2)); works for switching an output for my led

Of course I've read the API referece and googled the whole morning with no
results.
Unfortunately there are no code examples included in the API reference as i
know it from the function overwiev for PHP at php.net

Best Regards,
Frank
