Lpc2000

Thanks. A 3MHZ square wave? I think that AVR can't reach that..It's 
only 16MIPS at 16MHZ, and I sometimes I feel that the processor 
works slowly...
What about the compiler? and then... Is there any web site with 
project using this MCU, so I can take a look at what people do and 
how they work with the 2106.
Thanks very much
Ezequiel
