Lpc2000

hello 

does anyone know if there are some examples for I2C slave
reciever/transmitter mode for LPC2138 (or any other LPC), preferrable
in C? 
I've searched the net a lot, however I didn't find a thing. 

if anyone has an example (or at least something that resembles it), i
would really appreciate it.

thx
Zvonko
