I doesn' works. Here is the complete code for this example:
#include <compiler.h>
#include <cfg/os.h>
#include <stdio.h>
#include <io.h>
#include <dev/board.h>
#include <sys/thread.h>
#include <sys/timer.h>
#include <sys/event.h>
#include <dev/twif.h>
#include <dev/irqreg.h>

void Led1Off(void)
    outr(PIOA_OER, _BV(6));
    outr(PIOA_SODR, _BV(6));

void Led1On(void)
    outr(PIOA_OER, _BV(6));
    outr(PIOA_CODR, _BV(6));

int main(void)
    u_long baud = 115200;
    NutRegisterDevice(&DEV_DEBUG, 0, 0);
    freopen(DEV_DEBUG_NAME, "w", stdout);
    _ioctl(_fileno(stdout), UART_SETSPEED, &baud);

    printf("\nNut/OS Version: %s", NutVersionString());
    printf("\nCPU running at %lu MHz", NutGetCpuClock()/1000000);
    printf("\nProgram loaded...\n");
    outr(PIOC_PER, _BV(15)); //enable pio control
    outr(PIOC_ODR, _BV(15)); //set pin as input 
        if((inr(PIOC_PDSR) & _BV(15)) ? 1 : 0)
        	puts("\n Button pressed");


The LED's are blinking all the time but the reading from pin produce no
action.  I tried thes sample also with ext-header connector on port_pin pb22
also not successful :(

I don't know about this problem, maybe Ethernut requires that peripheral
should be explicit disabled before using of gpio ?
