Build Failed The project is configured for the dsPIC33FJ64GP802 with a new clean install of MPLAB8.30 include "P33FJ64GP802.inc" is in the program I've looked through MPLAB Help etc but am none the wiser Any suggestions ? wbr -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
