Yesterday there was a thread about someone having problem with a USBProg. The problem turned out to be a wrong mask value for one of the config bytes in the PICPRG.ENV configuration file. A few other related 18F PICs also had this problem. The errors have been corrected and updated software is available at http://www.embedinc.com/picprg/sw.htm. I sent a reply to the thread with this same information yesterday afternoon, but I still haven't seen it get to the list by this morning, so this is another attempt. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
