'Serial Port Programmers ?'

Here's one that looks like its been beat to death....

I'd like to hook my PC serial port up to my prototype and program
a PIC16f84 or a 12C509 (OTP) in circuit. Is that an original
concept or what !?

After hours of searching, I found several, followed a bazillion
(is that b or B?) dead links and downloaded about 5 including:

"No Parts Programmer" (parrallel port) which takes about 10 parts
I don't have;
several programmer programs last updated in 1995...some without
the schematics (PIP02??), some seem to work best on a 486..
LUDIPIPO - circa 1995 - very simple, does it do 16F84?

Is anyone still doing this ? Do these really work ?

Anyhow, I have a seperate 12V/5V power supply, MPLAB 4.00,
Windows 95 or 98, MAX-232 chip, and a Radio Shack just
down the street :-)

Suggestions anyone ?

Thanks in advance!

Ralph

P.S. Any good locations for searching the PIC web ring ? There was
some talk on a 'global' database for PIC stuff, but my hard disk
died and I lost that thread (and private e-mail too :-(

PTM: Yes, if your RS232 gives +/- 13 V

PTM: I have made my own card (one sided 30x45 mm and not ewen
overgrowdede, a friend made his 20x30 mm with SMC) with specs from
http://www.ebar.dtu.dk/~c888600/newpic.htm.
I changed this and that, but the idea reamains. Works fine even in a
laptop.

Ralph,

I am also disatisfied with the available on-line designs. Most of them
doesn't work with NT, and the ones that does, aren't free.

I'd like a device that could fit inside a 9-pin RS-232 plastic connector.
There's no need for an IC socket, just some type of connector for in-circuit
programming. If fitting a connector is too complicated, a 1.5m (5 foot)
5-lead cable will do. Remember that it will be used just for ICSP.

As for the software, it *HAS* to work with NT. If it works with other
platforms (Windows 9x, DOS), much better. Just a simple command-line program
will do. No need for fancy graphics or a even GUI. Ideally, the program
should be able to read HEX files directly for programming. Different
programs for different devices (12Cxxx, 16Cxxx, etc) are Ok. Alternatively,
a single program with a sophisticated command-line interface or
initialization (.INI) file is Ok too.

I am researching a little now for doing that myself. I am currently reading
the 138-page document 30277B.PDF on ICSP available at Microchip WEB site. I
don't have much free time, so I don't know when (if ever) the project will
be complete (but surely not before a few months). If anyone can or want to
help, you are welcome. When I'm done with it, I'll post the whole project
(including source code, schematics, PCB, and so on) to the PICLIST.

I have made some progress in this direction.  I built a Ludi-type programmer
and was also very frustrated with its lack of ability to run any of the
existing programming software under WinNT.  I also wanted it to be command line
software so I could integrate it with MPLAB.  In looking at the source code for
a couple of the serial port programmers that are out there, I found that the
reason that they will not run under NT is that they manipulate to the port
lines directly.  NT doesn't allow you to do this.  So I wrote a programmer that
was a serial port programmer that uses WinAPI calls to manipulate the lines
instead of writing to the port directly.  If you like you can have a look at
it.  The file is called PIXIE.ZIP and it can be found at the following site:

http://www.tapr.org/tapr/html/Fpice.html

I am running it on a 450 Mhz Pentium II with NT 4.0 with service pack 4
installed.  Experimentation has shown that it will not run on all hardware
configurations.  For example, I tried it on a computer running an AMD K6 with
NT 4.0 and it failed to work.  I don't know why.  So, bear in mind that your
mileage may vary.

If you decide to try it, please drop me a note with the results.  I'm trying to
find out what hardware configurations it will run on and which ones it will
not.
