With regards some programming problems users are finding with P16PRO http://www.dontronics.com/p16pro.html I have exchanged messages with Bojan on this, and there is now a version 3.61a This is a free download for registered and non-registered users. Bojan's responses and a little cut and paste from me follows: Feedback to myself or Bojan very welcome. >I got similar error somehow, with (AFAIK) 12CE519.

I get an error stating the configuration is not programming properly. Although a read of the chip proves otherwise. It isn't a show stopper, just annoying to have the error every time. Is something set improperly? Or is this common? >> Doug I have checked this and I think Microchip has a mistake in his datasheet for programming specification (FUSES). Microchip: - - - - - - - - - MCLRE CP0 WDTE OSC1 OSC0 I think : - - CP0 CP0 CP0 CP0 CP0 CP0 CP0 MCLRE CP0 WDTE OSC1 OSC0 I have updated the DEVICE.INI in version 3.61a and with this version it should be OK, if the Fuses settings are done in P16PRO/PICALL, but if you include configuration word in your source code, then you should also correct this settings also there. BTW: PICs are programmed OK anyway, only Fuses verification fails. regards, Bojan Dobaj ======================================= >> >I have already asked, but no answer till now, so I try once more (and >> >last): did any of you successfully programmed an 16C505 (except with >> >Picstart+), and if yes, which software and hardware were been used? >> > >> >It is very important for me, bcus I stuck in a middle of a project. >> > >> >Thank you. >> > >> >Regards, >> >Imre I finaly got sample PIC16C505, but I have no problems programming and reading it with P16PRO version 3.61A and with PICALL also. So I can't say, what was wrong in Imres case. regards, Bojan Dobaj Don McKenzie mailto:don@dontronics.com http://www.dontronics.com Don's Download Dungeon: http://www.dontronics.com/download.html Australian Electronics Ring http://www.dontronics.com/aering.html Win $500USD Cash.
