And I have no idea which switches you are talking about :confused:

My LPC1769 User Manual doesn't describe this switches ;)

#define SWITCH (1 << 26)            //SWITCH input P0.26

LPC_GPIO0->FIODIR &=~SWITCH;        //set input
LPC_GPIO0->FIOSET |= SWITCH;        //set high
...
if(LPC_GPIO0->FIOPIN & SWITCH)        //get pin
{
//damned, pin is still high :mad:
}
else
{
//wow, it's pulled low :)
