philips_apps has posted demo code for two different development
platforms but the code itself should work anywhere.  See the Files
section here and scan down looking for 'philips_apps' or the file
LPC214x_LPC213x Sample code for Keil.zip - a little more than half way
down.

In my view, and it isn't universally shared, the chances of getting
I2C to work without a logic analyzer are quite slim.  It would be
better to start with code that is known to work even if compiler
specific code had to be changed.
