No, bad idea. The 25mA spec means that is the max you should allow the port to source or sink, not the maximum it will source or sink when tied to power or ground or whatever. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The PICList is archived three different ways.
