Sorry for the wrong subject with my last message! Gents, I've purchased the pic16f84A (A is important!) and I've spent couple of hours to get programmed the chip (I have dtait lpt programmer and no problems with lot of pic16f84, sw I use is wpicprog32 from nigel goodwin v 1.2 and 1.22). The only way I discovered is to catch the chip with my fingers during programming and it works!! It seems the chip has other dynamic or static (1,0 levels or what) parameters, even I've read the migration docs at microchip site I do not know what is the trick?? Any suggestions?? (I've changed the pin 12,13 caps from 0 to 1nf - no help). Thanks, Igor. -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
