Lpc2000

Other than changing the device header file, am I going to get any big 
surprises moving up to a more capable chip?  Yes, less RAM but that 
isn't important.  Nor is flash.  I just need the pins.

I am using arm-elf-gcc 3.4.3.

Thanks
Richard

includes a ROM monitor image -- the same binary runs
fine on both 210x & 213x --except for memory sizes &
peripherals, there is not much difference (in terms of
basic functionality) between 210x & 213x.

Cheers,
-Mike.

Device Registers are greatly different in some cases.  The SPI is 
capable of sending more bytes per transfer and has a lot more settings.  
You'll probably have to make changes to your code to get it to run 
against these new settings in the registers.  There is an 
IO0{SET,CLR,PIN} and IO1{SET,CLR,PIN} macros...

Your experience with the LPC2106 will benefit you.  BTW, do not trust 
any device headers (e.g. LPC21xx.h) that you may download, I had to make 
significant changes to the one I found so that it would work with the 
LPC2138.  There were missing definitions, a lot of them!
