PCMCIA Parrallel port

1) Move to USB

2) Find out what port it is, and alter the software to suit. Help from
the author may be required, if the hardware settings aren't user
configurable.

3) Did I say move to USB? Parallel port programmers are becoming less
reliable because of critical timing, faster computers, new OP systems.

Hmmm

I have a CP-PIC877 develop board.

It used parrallel port in circuit programming.

Maybe I should fit a ZIF socket instead and go for dons mplay usb programmer
and transfre the chip.

sure, ZIF sockets are a lot cheaper these days than a few years back.

Mind you, those green counterfeit 3M sockets from "Choina" made the
prices plunge.

It's not address 3BC by any chance is it? That is an often used
address for laptops, so it would not surprise me if a PCMCIA card used
this address. Any good software should support this address.
It is doesn't, move to USB. In fact I'd move to USB anyway.

find a USB driven programmmer, you can get them for AVR.

Hey Don,

I have this development board which uses a 7407 and PNP and parra port for
programming.

I had an idea.

If ICSP is available for the USB PICSTART+ progarmmer you sell I should be
able to:-

1. Bypass and remove the existing 7407 and PNP cct and re-wire direct to
support the USB programmer ICSP
2. Dump the parralel port software and just use MPLAB with picstart selected
?
3. The USB programmer would still let me program 40 pin PIC's if I need to.
stand alone.

That would solve all my problems.

I just want to use MPLAB, and I don't want to have to swap chips all the
time.

Comments ?

If it is my dt001 board with the 4PDT Load/Run switch, then it makes it
very easy:

but any board should be able to be converted to the above without too
much drama.

Went a USB programmer from Dontronics - problems solved
