Since I upgrade my PicStart plus (btw, nice piece of hardware... :-) ) I cannot import/export ANY hex file to the program memory buffer: the error I get is "unsupported file format", but it *IS* a valid HEX... MPLAB 5.20 + 17C44 based PicStart plus did... Many thanks in advance. Ale -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
