How about adding support for the EA baseboard to PinNames.h. That way you can refer directly to PIO1_2 rather than referring to the schematic and then the pinout card to find the corresponding pin name of P17.

Hi Steve, The [[http://mbed.org/projects/libraries/svn/mbed/trunk/PinNames.h|PinNames.h]] supports pin names of the form: * pNN - mbed pin names * PN_MM - LPC1768 port based pin names So, for example, you can write p5 or P0_9. This also means you can use all the pins on the raw LPC chip if you make your own board. I assume the second form corresponds to the EA board pin names (if it doesn't, then the best solution is your own custom mapping file, as this is not something to have in the core libraries). Simon

Mostly the pin names overlap, but not all. For example p7 maps to P0_7 (mbed) and PIO2_11 (EA). I've created a mapping using #defines, because the mbed libraries won't accept an enum other than PinNames, and there's no way to extend/derive enums. Actually I guess it could be done with templates and derived mbed functions but that's a little over the top. So for anyone else using the EA baseboard and desiring to instantiate mbed objects referring to baseboard pin names here is EA_PinNames.h: <<code>> #ifndef MBED_EA_PINNAMES_H #define MBED_EA_PINNAMES_H // #defines to cross reference Embedded Artists baseboard net names to mbed pin names.
