i need help for pic programming...

[leonheard]

hi!

i dont have a serial port neither a printer port in my desktop, ( i want to program my pic16f84 )

i dont want to buy a pickit stuff.

so what if i buy a "pci serial port" will my diy programmer work?

i do have a usb to serial converter but it doesnt seem to work with it, and i read that it doesnt work with diy programmers...

Why cant you try usb to serial converter

I reckon it MIGHT work if:

1) The PCI card that you buy adds genuine serial port hardware to your PC. (COM1 or COM2 or both)

2) The PCI card gives out sufficiently high voltage levels to suit your DIY programmer. +/- 9 Volts might be typical.

3) The DIY programmer can operate with a modern serial port. Some DIY programmers expect +/- 12 Volt levels as supplied from older serial ports.

There are a few "if"s there, but maybe you will get lucky.

If you do get this to work, you will still end up with a programmer that is horrible to use.
