hello guys, i work with pic microcontroller and i has the following problem: i has a laptop which does not contain a serial port,so i has to build a parallel port programmer that has a software" works on xp", i searched over the internet and i got many results but i want to ask u about a one u tried and easy to build. i found this one which is really good but it needs a double face pcb, i will do it if i has to do it but if u can help me with a simple one i will be thankful. take a look here

if u have a pcb for this progremmer send it to me, so a less effort is needed to make it



thanks

You're not going to like this.. If you're an embedded developer (or techie fiddler) then the new machines / laptops without parallel or serial ports are practically useless, with XP coming not far after for it's restrictions on direct port access.

If you're serious about PIC development either get a USB ICD2 or pickup another machine specifically to program on and run 98SE on it. HVP is definitely the direction to go, LVP is so restrictive if you accidently CP the device, with HVP you can erase the CP along with the chip.

Don't be a tightarse, I did it for about 6 months and then realised how much it was restricting me when I bought an ICD2.

Sure, you can program the parallel and serial ports on an XP box.. you just need the (free) I/O driver Inpout32.dll for Windows 98/2K/NT/XP from

to get to them. The site has plenty of samples, tutorials, etc. downloads to teach the details. Another great resource for port I/O is Jan Axelson's site at

Jan also has a book and lots of info on USB interfacing as well.
