Jan-Erik You didn't read the original bit - the bit I quoted. The original project as written up in a Design Ideas section of EDN magazine uses an AT90S6515 micro with an FTDI245BM to interface a GPIB bus to USB. Hence why I said "ditto" to the bit I quoted, as I have also been looking at doing this as well. It would be nice to use a USB PIC in place of the FTDI245 and AT90S8515. The source files for the AT90S8515 are available through a link given in the article. The source is written in C. Anyone interested should look at http://www.edn.com/article/CA6290453.html?spacedesc=designideas where there is an HTML version, and a PDF version available for download. The PDF version has all the design ideas from that issue, and this is the second or third. Use the html version for the download link for the source files (called complete.zip). It also has the FTDI driver, and Labview interface module. -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
