Hmm... I'm not an expert at that but usually just some resistors on I/O pins should prevent any dangerous currents due to this. -- Hector Martin (hector@marcansoft.com) Public Key: http://www.marcansoft.com/hector.asc -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
