I'll make it easier ... go into the examples folder, which will be something like the following:

C:\nxp\LPCXpresso_4.0.5_123\lpcxpresso\Examples\NXP\LPC1000\LPC11xx

and unzip the file "NXP_LPCXpresso1114-302_2011-02-07"

Inside this zip file you have all kinds of examples, and you just need to search for IOCON.  For example, open:

i2c/driver/ssp.c

and look at lines 134 and following.

If you want to understand what 0x07 and 0x01 mean, you'll have to look in the user manual (which I'll provide here if you can't find it):

http://ics.nxp.com/support/documents/microcontrollers/pdf/user.manual.lpc11xx.lpc11cxx.pdf

Look at section 7.4 (p.59).

You can see the bits that you need to set for each pin to control the functionality of the pin, the internal pullup, and potentially other settings.

Try (seriously) to understand some of that first, and if you have questions that show you're making a (serious) effort to understand, I'm sure people (myself included) will be happy to help.  But just asking for answers that you can easily find yourself isn't helping you or anyone else, even if I could have given you the answer with far less effort than the above reply.

Honestly, you should really put some effort and thought into this yourself.  It seems you're just waiting for people to spoon feed you an answer you can very easily find in the existing examples.

Just do a text search in the examples folder for "IOCON".

If you've made a small effort to understand how IOCON works, people here are happy to help beginners ... but no one would be 'helping' you by doing all of the work for you with zero effort to understand and learn things for yourself.

You need to do some thinking yourself before you can "think outside the box". ;)

Which error?

BTW: Which LPC are we talking about?

Could be:

LPC_IOCON->R_PIO1_0=0x0000;

Do you know that this IOCON struct is defined in your LPCxxxx.h ?

Why don't you look up the examples?
