What's the best way to drive 5v logic with the LPCxxxx GPIO? Pull up resistors? I seem to remember reading somewhere about using pull-up resistors, but I don't see any information in the LPC2106 reference manual on how to put the outputs in open-drain mode. I'd appreciate any advice on this. Thanks. Also, thanks to those who replied to my previous questions. - Chris Graham
