I finally have one of Leon's lpc210x proto boards assembled. The problem is the MAX3232 runs warm and seems to be drawing 150mA or so--it varies a bit. The lpc2106 runs at ambient and has detectable 10MHz on its clock pins. Removing the MAX3232 from the board causes it to use very little current ~10mAh, so I'm assuming the CPU is okay. Is there some common failure mode these things experience? I'm pretty sure there was no reverse voltage, etc. Could a poorly connected cap do this? I *really* want to talk to this thing, but if the serial interface won't work.... Cheers, David
