Hi, Does anyone know what the PM3 firmware update does? I notice that the updated PM3 is programming the 18F2520 quite a bit faster now, but I'm wondering why and how. I didnt notice anything on microchip's site. Thanks, James -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
