Just for kicks, try using the attached HEX file: MM5369.HEX I zipped it up for you. This is the HEX file I just programmed into the PIC and it works. Also, what is the checksum you get when you assemble the project in MPLAB IDE? I'm getting 0xF671 with MPLAB IDE v6.62. 1) Please post the checksum you are getting in MPLAB IDE when you assemble the project. 2) Let us know if the attached HEX file works for you. Best regards, Ken Pergola ------=_NextPart_000_0006_01C4D19E.6EFDA0D0 Content-Type: application/x-zip-compressed; name="MM5369.zip" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="MM5369.zip" UEsDBBQAAAAIAAGldzH8YaXAMAEAAEEDAAAKAAAATU01MzY5LkhFWG2TW47DIAxF/yt1L5eXDf0j BPa/pLHBTOhoUEkrODanxvnAQ0fUx6jv18fBhiw1RlOACAhNfss3MdBlumSwTpoPJCYUDXQdLeta AONC9WzwPI0QfXwA51AjSY4bVYO5GBx0XgeYJFOcMCMvOHSD419Ysx1KKaO17ZxkbtDTBGM6nH1D vWAwaXbxC3YkpwcUxRoGKg2DecG/fl9wXkotGpw1wPyKf8DollJR58vgcjhHXiVLYZ1SxwouG64w UIqf6nfJNtx36S6DZ7ajZK09Sj0b3LR8bfndhzP5pUT9uO4b62Z6OUCtd36Uru3c/4P7givDa1P5 Xeeh1eAJEctVyy3OS9U23eu3/kERVl52JqRtkrWHd0DRppcj5hvwNbTRb930bgyRG7d8tINsX1bf rx9QSwECFAsUAAAACAABpXcx/GGlwDABAABBAwAACgAAAAAAAAABACAAAAAAAAAATU01MzY5LkhF WFBLBQYAAAAAAQABADgAAABYAQAAAAA= ------=_NextPart_000_0006_01C4D19E.6EFDA0D0 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit _______________________________________________ http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist ------=_NextPart_000_0006_01C4D19E.6EFDA0D0--
