Check your programmer software docs. Maybe it needs some option to read back everything into a HEX file? Why not create a HEX file again from the source code? > and also a Flash version of a PIC. There will most likely be config bit differences, and possibly memory map differences depending on how different a PIC you chose. These should be small changes to the source code if it was written right, then rebuild for the new PIC from there. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
