Hello,

I am trying to get IO- Port P1.14-P1.20 and P1.10 as GPIO to work. Everything works fine except P1.14 and P1.10. Here is my Code:

LPC_GPIO1->FIODIR = 0x1fc400;
LPC_GPIO1->FIOSET = 0x1fc400;

Do I need external pull-ups for this two Ports or what is my problem?

Thanks in advance!

Oliver

Yes I checked all of these registers... They are all good!

But  I saw that port1.14 and port1.10 is connected to a LAN controller on the xpresso board. The code I am writing is not for the xpresso board. I am just debugging on it.  Thanks for helping me!
Regards,
Oliver

Which function is selected in PINSEL2 register for this pins?

What about your FIO2MASK register?

Is there anything connected to this pins?

Did you debug these registers already?
