intellijel Posted May 24, 2008 Report Share Posted May 24, 2008 I built the Pic Burner hoping that a USB to Parallel cable would work with it. It doesn't...or at least I can't get P18 to recognize it. I would read the helpfile or e-mail Sprut.de if everything wasn't in german!!!I don't have a computer with a parallel port (like most people these days).What USB based programmer can I use to program the PIC18F4620 and PIC18F452.Is there a simple circuit I can build so that I can use a Pic Kit 2?Or should I buy something like this: http://www.electrokits.com/electronics/programmers/100.htmHelp greatly appreciated, I need to get these burned ASAPbtw, I could buy them with the boot loader burned in from smash tv but the price of buying four or more chips from him is the same as buying a commercially available burner and then I can get an almost endless supply of free chips from microchip.com as samples.

intellijel Posted May 24, 2008 Author Report Share Posted May 24, 2008 From another site I found this connection scheme:PICKit2 pins1 - VPP to 1 from PIC18F4522 - VDD to 11 and 32 from PIC18F4523 - GND to 12 and 31 from PIC18F4524 - RB7 to 40 from PIC18F4525 - RB6 to 39 from PIC18F4526 - not usedI assume PIC18F452 and PIC18F4620 are interchangeable in this situation as well?

stryd_one Posted May 24, 2008 Report Share Posted May 24, 2008 Yeh they program the same. One thing to watch out for is that it supports HVP mode, which I think that pinout does? Quote Link to comment Share on other sites More sharing options...
intellijel Posted May 24, 2008 Author Report Share Posted May 24, 2008 Yep the above worked.So personally I would highly recommend buying a pic kit 2 (or clone...eitherway they are under $40) and then you can use the Pic Kit 2 software to program the PICs.I made the connections listed above on a breadboard in about five minutes and had no problem programming a PIC18F4620 Quote Link to comment Share on other sites More sharing options...
stryd_one Posted May 24, 2008 Report Share Posted May 24, 2008 Thanks for the update :)I'll just keep buying motherboards with LPT ports I think! Quote Link to comment Share on other sites More sharing options...
