[En-Nut-Discussion] Olimex SAM9-L9260 board

[Lars Tore Skau]

I don't think NutOS will ever be able to replace linux, but its great to use
for small applications where basic OS functions are needed.

On the CD that comes with the Olimex card, you will find a working linux,
and a sam-ba which works with the nand.
I use the newest SAM-BA with some minor modifications (the nand ID and
parameters must be added to the nand applet)

To read an input pin, try this:

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)
{
     //pin is high
}
else
{
    //pin is low
}
