'PIC16C84 programmer'

Hi;

I have joined this group about 10 days ago. I have
just purchased my first PIC16C84, together with a couple of
other components and a PCB, with a bit of prototyping
area (mail order; in Japan).

Now I need a programmer! I found a couple of programmer
packages (schematics+software) over the net, and will
build one of them myself (we are short of cheap PIC
programmers in Japan!).

The most important criterion for me is reliability, so that I
don't have to decide whether it is my code that is wrong, or
the programmer is acting up!(experience from a home brew EPROM
programmer...) A decent user interface is necessary here; not
the colorful Win95 type thing, but one that tells me what is
going on clearly (DOS preferred, but anything is fine-UNIX,MAC).

Given this short background, can someone suggest a "the best"
design among those available over the net for free?

I have been making circuits for about 15 years, about 7 of them
with microprocessors; so design complexity is not an issue...

Well, what do you people suggest?

Thanks;

Hi!

I posted a request for suggestions about which PIC16C84 programmer
to build. I have already received a couple of mime encoded
(LARGE) files. While I am thankful to those who take the trouble
to send the files, I would appreciate a discussion of which
setup is better than the other, and pointers to where they can
be found! Otherwise, I will have to build all the programmers
to see for myself if they work properly or not!

Thanks;

AFAIK there are two types of programmers out there. Those who connects to the
serial port and those who connect to the parallel port of a PC. The serial port
type is simpler and uses the port signals for its programming voltage. Since
not all serial ports are identical and often the manufacturers uses lower
voltages to save power (especially on laptops) you might get problems with a
serial port programmer. A parallel port programer wont have this problem since
it uses a external power supply but this is naturally more complicated.
I use a serial port programmer myself and it took a bit of tweeking before I got
it right. I found that it somtimes can help to use an external 5v supply
(preferably taken form the gameport). Also I found that some PICs will program
and some will not.

I started out using the programmer I posted to you. It works fine for
start and exploration Circuit. I'm now using the Starter Kit supplied by
microchip and the MPLAB software from the MICROCHIP site:

http://motserv.indirect.com/home2/mothome.html

I've also Explored a local ICE that includes an ICE hardware board using
a PIC with dos based software. The also sell hardware and not software
so u can look at the program for demo purposes.(Let me now if you are
interested) This package also supports the typical 8051 Pseudo code that
extends the PIC ease of programming.

That's as far as my experience goes.

Hope I've done better this time.

Hey, don't send attachments to the list.  I don't need or want your
progammer.  This wastes my already too slow bandwidth.

The better option is the e-mail individuals with the files or put them on a
web site somewhere.  There must be a PIC archive somewhere.

I did not realize the conseqences of my actions. I'm not using a modem
link and I did not experience the problem myself before. My apologies
for your time wasted.

I'll keep that in mind to first send out attachments at request.

Best regards

Jattie.

PLEASE don't ever send 400K of files to everyone on the PICLIST
again... Send them in e-mail, or put them on an FTP server or
something.

Remember that some people still use 2400 bps modems... Those people
were forced to wait nearly half an hour for your message to be loaded
into their mailboxes.

Have a look at:
http://www.labyrinth.net.au/~donmck

There is the free circuit and overlay of a Printer port driven
programmer based on the original design by David Tait. There are free
software drivers that include a disassembler, and support for the
following devices: 61,62,63,64,65,71,73,74,84,620,621, and 622.

This design was introduced in Feb 95 and has the advantage of using a
4PDT switch to allow a Program/Run mode for the 84, so it will program an
84 in circuit in around 2 to 10 seconds. About 250 have been built up on
a Printed circuit board I can supply, however I would think that many
more have been bread-boarded by home constructors.

The attachment that I've send to the PICLIST group Included the David
Tait version with a few hardware and Bugfixes. The Guy who fixed
them Robert Farrer from Farsoft Computers included David's Copy Right
Notices and redesigned his hardware layout with Notes on the Fixes.

For more Info you can mail me Directly. Farsoft is not available on the
Internet but is on a local 14400 Modem Bulletin Board and I've Got most
of their stuff on My PC. I've got a propoasl from several guys to make
use of their FTP sites to uoload the software. I'll speak to Robert and
see if we can arrange that. He's converted most of Microchips samplecode
to run on '84's as he also does a course on PIC micro's wich is very
efficient. People with no experience can learn in 6 weeks to be quite
efficient programmers.

Let me now if there's interest and I'll forward all the requests to him.

Thanks.
