help,
       can anyone tell me if it is possible to use the pic16c54/55/56/57
programmer to program the pic16c84 without serious adjustment, if so how.
I know its possible to program the pic16c84 using the rs232 port on the pc
but would prefer not to use this method.

The chips don't have the same programming setup. The 84 is more like the 71
than the 5X series. There's no easy way to convert a 5X programmer to
program either the 84 or the 71 because the latter two have serial interfaces
and their programming voltage pins are located in a different place.

I suppose it might depend on the programmer, but the Picstart I have
manages to program 16C84 and 16C71 with no problems.  I have read that
you need the more modern firmware (1.5?) and software (on the ftp sites,
or with current picstarts) in order to correctly program the fuses on the
16C84, but mine had no problems whatsoever.

The ultimate check is the current databook (1993 in the UK ;-) which has the
programming details for the whole range.

Ian

p.s. don't you mean the parallel port on the PC?

Not quite as the 84 and 71 have BOTH parallel (like 5X) AND serial interfaces,
like I said (though it isn't back here yet) PICSTART copes quite well, I used it last
night ;-)

=%-)

Ian

p.s. I haven't got my data book here, but don't 16C5X and 16C84/16C71 all use *MCLR as
their Vpp pin, in which case it is on the same pin. (Could be wrong... often am ;-)

{Quote hidden}

Well now I can actually say something because I have my data book here:

Ian is correct. The *MCLR pin is the same for the 5X/71/84 as is the RB6 and
RB7 pins. But the programmer has to be smart enough to run the serial
algorithm on the 71 and 84 to put it into parallel mode. So if the programmer
is specifically designed for the 5X series, you'll have to change the
program for the board in order to get the 71 and 84 to work.

'Pic programmer'
1995\08\10@174724 by Jorj Bauer

Okay. I'm new to PICs in general, so don't be shocked at how little I
know. :)

I've been trying to program an '84, preferably via RS232. I've tried
several schematics (some parallel instead), and have intermittant
results.

I have two schematics that I'm particularly fond of (because I'm trying to
integrate the programmer into the final "product", and these lend
themselves to it well). If anyone has used either of these and/or can give
me helpful hints as to what problems they've found, I would much
appreciate it. If anyone knows of a "better" circuit (i.e. one that's
simple, that has freely available software for programming it, and it
works), I'd love to know.

#1.
I first tried the RS232 circuit that runs under PIP. Its schematic is
available from ftp://rasi.lr.ttu.ee/pub/SIS/CAD/DIY/BITMAPS/com84.gif. It
looks like the serial info is getting to the pic; however, I don't know
enough about the programming timing to tell if it's working correctly or
not. PIP-02 (with pinapi driver installed) goes through the motions, and
reports "Error Programming Device!".

#2.
I've tried the blowpic program and its related circuit:

;                                                       PC Power Supply
;                                PIC16C84

;                               `----+---' |   2.2K Resistor (*)
;                                    |    =*= 10uF Capacitor (*)
;                   (25) GND --------`-----`---------- GND
;

This is the only one that I've gotten to work at all. It won't work for
long periods of time, then suddenly, when I'm good and frustrated with
it (and have assumed that I've blown out the pic), I get it to program
correctly (i.e. run a different program than was in it last).

Help?

I was expecting first "Error ..." reports from users.
Few questions I need to know to help you out:
Does PIP read the PIC using RS-232 serial programmer?
Does it erase the chip? If getting "Error .." report
does the chip get programmed partially or not at all?

FYI there is a small test program four our drivers -
/pub/sis/msdos/drivers/drvtst1.zip
that program can be used to test drivers/hardware.
You can use that program to set programmer pins and
to read them back. Did you verify your RS-232 programmer
hardware with that program?

>I've tried the blowpic program and its related circuit:

We dont have currently support for blowpic schematics
because it has a manual switch. However as it seems
that now there is at least one user to that schematics
we will possible introduce drivers also for hardware
with manual VPP switching (ie blowpic design).

Hints on programer selection: there are several schematics
published, lots of them already are supported by our drivers.
And our software is free. If selecting one of those programmers
then software support is already there. If you find a programmer
you like, but we dont have driver yet, let us know!

If your final "product" is a software package please ask us
about licensing of our programming routines/drivers. You would
get support at once for all the hardware we support.

If your final "product" is a hardware with in circuit programming
of PIC's you may also ask for programming support from us,
DOS units or Windows DLL's available for in circuit programming.

PS we had some problems with PIP and RS-232 programmer ourselfs
howevere only in Windows 95 DOS boxes. We have found that that
exiting PIP and removing and re-installing the RS-232 programmmer
driver has solved that problems. We are working on that problem
currently, but until it's solved, please try to re-install the
driver if having problems to program from DOS boxes

Did You try it on another PC ?
Maybe Your PC or its power supply produces too much noise.
I've tried several LPT and RS232 schematics and all worked fine.

I've integrated my version of an RS232 programmer into an 16C84 module.
(Looks like a Basic Stamp).

The schematic is correct, but it seems that some versions of the 78L05
power regulator draw too much current from the port.
I've used Zener diodes in my design.

This should work.
If not, try to connect a small capacitor (10-1000pF) between Vpp and GND.
I can send You my TP source, if You want.

This should work under all circumstances.
Except if You are using a non compatible parallel port.
That leads me back to the distortion theory.

PIP thinks that it can read the chip, but it can't. It doesn't program it
at all (I have a 19-word test program that I managed to get into it with
blowpic that I'm overwriting, but the old test program stays).

I haven't tried this, but will.

My final product is for personal use only, and isn't going to be a
commercial product, or I would have asked these questions as well. Thank
you for the information anyway.

This is good to know. I'm doing this directly from DOS (6.2); if I can
get the RS232 setup working, I'd love to run it under dosemu in Linux.
Anyone know of programmers that run from unix directly? I could always
try to port blowpic...

Yep, I've tried it in three pc's. Two 486/33's and a p5/100.

I assumed that it was drawing too much when I first encountered errors.
For testing, I removed the 78L05 and replaced it with a +5v power supply.
Is Vdd switched during programming?

> This should work.

Thanks for the offer. I'll try using a zener.

Well, it works about four times a day, when I get really mad at it.

Dear J.L.Iehl

First, may I suggest that you start with the 16C84 as you don't need to
erase it and can program it in-system so it does not ever have to be removed
from your circuit. Very convenient!

There are many people supplying 16C84 only programmers cheaply,
@spam@donmckKILLspamspamtbsa.com.au is one but like myself  is in Australia.

I also sell PIC programmers and export to many countries. I  have a cheap
kit that programs ALL the current PICs (16C5x,
16C61/62*/63*/64**/65**/71/73*/74**/84 . This kit is for hobbists and
beginners but still is very good.  The software interface is exellent and
easy to use. Are you using microchips BBS on compuserve? If so I can send
you a demo.

* Requires you to wire your own 28-pin adapter socket as pin out is different.
** Requires 40-pin adaptor PCB (supplied)

E-mail to me if  I can help you.

If you want to program a 61,62,63,64,65,71,74,84,620,621, or 622, I have
a bare board at $15 US.
If you really do need a 5x programmer, then these are a little more
expensive.
I suggest the programmers available from Jim Roberson (Newfound), Robin
Abbott (FED), or Chris Sakkas (ITU) (hope I spelt that correctly Chris).
Theses people can be found from my home page links. Don...

Does your Amiga have a serial port?  If so, contact EraseMEcarlspamspamspamBeGonecarmacon.com and
ask about porting their Windows app to the Amiga OS.  The hardware is

It uses a Parallax programmer, with a new '57 chip to drive it.

Hi Alex,
well, if you decide to write software for the amiga platform, maybe you
could use the hardware from the P16PDG, under pc-control it's already
possible to program more than 45 PIC's with it. It is available from :

  Alex, I use to be an Amiga developer for 10 years. I have some
assembly modules that allow C programs to interface with the parallel
and game ports in a `system-friendly' manner. There are three archives.
One provides general purpose routines for the parallel port. One
provides routines for implementing an SPI/Microwire interface. And the
last one provides general purpose routines for the gameport. All you
need to do is link them with your C code. I've included documentation
and function prototypes. The modules are compatible with Manx and SAS.
Check out:

     http://www.teleport.com/~thandley/Wilbure.htm

  As far as programming info, check out Microchip's programming specs
at:

     http://www.microchip.com/10/Datasheet/Specs.htm

  I no longer own an Amiga and I was about to remove the archives so
you may want to check them out in the next week or so.

That's right, but i was searching for a freeware programmer... so the

Oh.. so it's commercial.. i need something freeware or, at least, shareware...
anyway it shouldn't be too difficult to write a serial pic programmer....
parallel ones needs a bit more time.. but not too much i think...

Do you think they'll do it?!  I always wanted a PICSTART PLUS driver for

The data returned will be all zeros instead of (all ones || a mixture of

Try it some time - put a PIC in backwards and read it.

:-) you surely know that a pic need an high voltage on Vpp to read out data...
if is applied on the wrong pin... kabooom! :-) On eeproms, Vpp
is also applied on A9 to read out the electronic signature.... if
A9 is not where it's supposed to be (maybe because the chip

My programmer uses a 2mA/100mA switchable current-limitted supply: the PC
turns the supply on for 2mA, makes sure the chip works, then (if applicable)
switches the supply for 100mA.  As far as I can tell, applying even 13.5v
(current-limitted to 2mA) for a half-second or so won't do any damage.

Hi people,

   I've built a PIC programmer based on the PROPIC by Octavio Nogueira, and
I got one problem:

    The 5v regulator (mine was a 78L05 and now is a 7805) enters in thermal
shutdown everytime I plug the programmer to my parallel port!

   I'm using a 24V power brick from an old HP ScanJet 4S, and, at first, I
think the problem is the current sink of my parallel port. Does anyone knows
how much current does a parallel port output sinks when low? Since I got 5
outputs being used at level 0, I calculated a 100mA sink, and that leads to
a dissipation of about 1.9W. I tried to use a  big heat sink, but it's not
working quite well. Anyone got any suggestions?


   Thanks

   Thank you all that supported my question! The problem was too simple.
The lady that sold my components gave me 10 ohms resistors instead of 10 K
ohms resistors. Since I'm color-blind, I didn't pay any attention on the
color code! So, all pull-up resistors were burning hot too!

Hi PIC Gurus,

The PICSTART Plus does no verification on programming PICS.
So we are looking for a Programmer for our (small) production.
Are there any experiences with PIC-Programmers ?
Is PROMATE 2 ok ?
Are there others ?
Are there any experiences with general purpose programmers which
also can program PICs ?

I have used a Needham's EMP-20 for years. It programs many devices,
including PICs, and verifies at multiple voltages. It also seems to be
much faster than a Picstart Plus(I also have one of those).

About $450 USD

I bought mine at Digi-Key many years ago because they include the
personality module for PICs, normally an extra $25.

The Picstart and Promate are a good choice if you need to program the
newest devices, because Needham's is usually 1 month behind the release of
new chips before updated software is available.

I use promate 2 for more then 2 years. I am very happy with it.
It is number 1 programmer.
1. you do not have to replace any chip for firmware update.
2. there is no ground loop between pc and programmer
3. you can program serial numbers too.
4. Excellent technical support if you have any problem
will replace it next day wow.

the unit it self is 800$
each probe is 150$
with ICSP you can program all except base line  350$.
I would not bother with 3th part venders you will end up with headache.

As a 'newbie' here on the piclist, I advanced to the point
where I had decided to buy the PICSTART programmer to utilize
with the 16C84.  I looked up this item in both Digi-Key and
Jameco catalogs and found out that:

Jameco only lists a PICSTART Lite 16B for $109.00
Digi-Key only lists a PICSTART Lite 16B for $69.00

...very confusing....

I called Digi-Key to order the 16B and the girl told
me that it has been obsoleted by the manufacturer.  I
decided to not order the item at that point until I
get more information about this.

Would anyone on the list know if Microchip plans to
sell another programmer like this to replace the PICSTART?
Is there another programmer that is equivalent in price
and performance?

Thanks for any information about this...

What is the relationship between the PICSTART 16B and the

Jazzy,

Drop the "l" in the ".html" below. I was number 12 on your site. Nice job of
taking free designs and selling them. Sure cuts down on the R&D costs.

To all new PICsters out there, if you are thinking about building one of the
free serial F84 or parallel style programmers you might want to consider
one of
these. Prices are reasonable.

I use ITU programmers myself for development.

Have a GREAT day,

Mark

'PIC Programmer'
1998\11\02@055114 by aya Baptista

There are several schematics for PIC16C84 programmer on the Internet. Most
of them use the TXD line from the serial port to obtain +12V (mainly the
ones that use COM84) which they wire to the MCLR (Vpp) pin via a resistor.
I'm intrigued on how they do this. In order to get +12V on TXD, one must
continuously transmit zeroes which I think is impossible (because of the
STOP bit which is -12V). If TXD ever get negative, I think that would ruin
the 16C84, or not?
Other thing:
to verify the contents of program memory, they use CTS to read from the
16C84. But what can be read is TTL levels 0 and 5 volts which are
incompatible with RS232 levels of -12 and +12 volts. I can't understand how
does this work either? What will be read by the serial port when there's a
zero voltage or 5V at the PIC data output?

Thanks in advance,
AndrŽ Malafaya Baptista

 Use the BREAK bit in the control register.

 It may not be healthy, so you clamp it to ground with a diode.  A
Schottky would be good, but what works, works.  A 12V Zener will limit
MCLR/ VPP in both directions.  RS-232 drivers are by definition, short-
circuit proof.

 A low or high as appropriate.  The thresholds of the 75189/ 1489/
14C89 are about 2V with some hysteresis.  The PIC is not TTL anyway,
it«s CMOS.  It works fine up to a couple of metres, possibly much
longer.

 Long ago (18¸ years) and far away, someone wanted a variable threshold
input buffer for a laboratory interface to a computer.  I piped up "use
a 1489, it«s designed for the job, guaranteed against transients, comes
four to a package" and gave them a copy of the datasheet.  "Eureka" (or
something along those lines) he said, but I never did get my datasheet
back.

 Each buffer in the 1489 (75189) has a third terminal.  If you connect
a capacitor to it, you limit the bandwidth.  If you connect it via a
resistor to the output or ground, you modify the hysteresis.  If you
bias it (through a resistor) from a potentiometer between plus and minus
5V or 15V, you can adjust its threshold between somewhat negative and
quite positive, but it *defaults* to about 2V.

 It«s a very versatile IC.

This IC you refer, does it exist at the output of the serial port? Or should
I put one there?

 The 1488 and 1489 "always" exist on any standard serial port (And on
the better ones, they're socketed so if you should burn them out, you
can replace them, IMHO at least.)  Some LSI circuits may include them
internal (on the FGPA etc.), but not always.

 The really good thing about those is, they don't usually burn out
unless you do something really nasty abusive to them {like wire 117VAC
to a serial port, or strike it with lightning}, they're reasonably tough
IC's, billions produced, & I haven't replaced many that I can remember.
And even Radio Shack carries spares, should you ever need more <G>  (Way
overpriced tho.)

Often instead of a 1488 and 1489 you'll see a MAX232 or the like, which
integrates receivers, transmitters, and charge pumps.  In PCs the variants
without the charge pumps are often used, since +/-12V are available.
However, many PC power supplys are so wimpy on -12V that good multiport
serial boards use the charge pumps anyhow.

> Some LSI circuits may include them

I've never heard of such a thing.  Can you cite a reference?

What I've always thought would be useful would be a small chip combining
a 5V linear regulator, undervoltage detect for reset, and a MAX232 (or
even 1/2 of a MAX232, only a single channel each of tx and rx).

In PIC circuits for non-commercial use, I often just use resistors to
interface the PIC to a serial port.  EIA-232 signals are active at negative
voltages, which is normally taken care of by the inverting nature of the
buffer chips, but the PIC can do that in software.  Of course, this doesn't
meet EIA-232 specifications, but it works well enough for casual use with
short cables.

My full-duplex software UART code has conditional assembly directives to
include the necessary inversion.

much cheaper.

 Mmm, these are the 1488 and 1489.

 Interesting suggestion.

 He means that virtually all of the "Super I/O"-type chips such as the
Goldstar "Prime 2C" or Winbond 83758 etc., used on "paddle" cards and
"all-in-one" motherboards in recent years, include the RS-232 driver
functions, drawing +/-12V from the PC supply.  Smoke the RS-232 port,
and your motherboard is "history".

 For embedded apps, it would be quite nice.  The trouble is
compromises; whether or not you need a low-dropout, low-quiescent or
high-current regulator.  The MAX232 has moderate idle current with no
shutdown pin as other MAXs have.

 Yep, Shoulda mentioned the Max232 <G>  I see more 1488's/1489's/etc

 Take a look at a DTC 2280 IDE (or most any other) ISA paddle card, or
a DTC 2278E VLB HDC/IO card, or a current pentium motherboard (I can
supply a bunch of digitized photos.)  If you can find a 1488 or 1489 or
MAX232 on there anywhere, I'll mail you a 16C84 that's sitting here in a
tube <G>  (2 SMC IC's, 1 100-pin and 1 68-pin, do the work, I assume, on
the DTC 2280 card. <G>)  The DTC 2278E uses that super IO SMC 37C
chipset, works like a 16550AN pair plus 1488's/1489's.

Yes, however there is a way to do this by setting the BREAK condition in
the serial transmitter. Look up a NS16550[A] datasheet / register level
programming. The 12V method works only for the 84 as far as I can tell.

Most serial receivers are slightly assymetrical to accomodate just this
case and to give the receiver a defined state if not connected to
anything. They thereby violate RS232 level standards slightly, but it is
for a good cause.

I'm trying to break into the PIC scene.  What I would really like to
find is a programmer that fulfills 2 criteria:

a. can program 12C67x's

b. costs about $50 or less

The ITU programmer would be perfect, but I see from this list that the
availability of that product is uncertain at best.  Their phone has
apparently been disconnected; I assume that Chris was the sole

Does anybody know of another option??

 You haven't looked at the articles!  The serial-port programmer is for
almost *all* the ISP PICs.  Sure, you require more current for the
EPROM devices from the 12V supply but - the secret is a capacitor!

No, there are parts from Maxim, LTC, etc. that integrate five EIA-232
receivers and four transmitters on a single chip, and they are available
with or without the charge pumps.  The w/o parts are commonly found on
motherboards these days, because two of those take up a lot less space than
the two 1488s and three 1489s that would otherwise be required.

All parts have compromises; that doesn't prevent them from being made.  It
just prevents them from being used in the applications for which they are
unsuited.  Often the manufacturers choose to make multiple variants with
different tradeoffs.

The picstart plus is a good programmer to consider. It does all the pics, has
sensible socketing with all pics being top justified in the one socket and is
mplab compatible.

The down side is the cost and occasionally you hear of people having comms
problems with it. I don't think that is common though.

At the cheaper end there are a stack of firmwareless programmers known as
"Tait style" after their "Father" David Tait. The quality of these vary
and lack of *real* support can be a problem. Still many people cut their
teeth quite happily with them. Can't argue with that. The Web is full of these
designs. I should add, some of these are very well engineered and presented
(PROPIC II) but the cost puts you back in the same ball park as the picstart
plus IMHO.

For the best of both worlds consider looking at the stuff I'm doing. Follow
the URL in my sig below. Maybe I can help, maybe not.

It's more common than you think. However, it is not usually caused by the
PICSTART plus. Microchip's on going development of the MPLAB software often
makes things that 'did work', stop working. They do fix things though. But
downloading the latest beta version of MPLAB every time is a pain in the ass.

I use and sell the P16pro. It represents superb value for money.

I have also emailed Jim for details on his MPLAB interface for this
product. When I can get my hands on that, I will have the best of both

I cannot argue, only suggest that the message of common must relate to units
sold. I would have thought many, many picstart pluses have been sold. I don't
see a disproportional number of complaints, however this  doesn't mean the
distributors are coping flack behind the scene. The picstart plus looks
well designed to me and doesn't cut a single corner with the programming
specs. I would be keen to know more on the picstart plus reliability...

>downloading the latest beta version of MPLAB every time is a pain in the ass.

A very, very big one at that and a turn off from the picstart plus. Using
MPLAB
every time ot program a pic is also a pain, that is why I use my own driver.

>I use and sell the P16pro. It represents superb value for money.

Well I disagree on "superb." Numerous people have promoted this programmer
without a mention of the software registration of USD$20. This makes it a
USD$45 dollar programmer and at that price it is good value but still worth
looking around.

(Then there is the issue of the mistakes in the device file that haven't been
corrected.)

I'm always listening. but I don't have a magic wand. Things are progressing
slowly. I am aiming for a no bugs release but maybe there are some questions
involved before I start interfering in someone else's business. I think people
should register their software first.

Every single programmer that I have sold, has been sold to program F84's.
This can be done with the David Tait software, and that's free. To program
anything else, you could not use the David Tait software without modification.

I also looked at the Nigel Goodwin software and bounced a few emails with
him. Never got it working though. Anyone else tried?

I don't know of any mistakes in the device file - but then, I have never
asked. What are they? I will certainly chase Bojan on these issues.

Hello PIC-listers

Can anybody point me to a site where I can find a programmer for the 16C74 that
I can build myself?
I am having a really hard time programming such a beast with my PROPIC v.1, and
now I want to try another programmer.

Thanks in advance
Henrik Nowak

Hi Henrik

My Propic used to work fine with th C74. I did have a few problems
though, I kept getting error at mem 0 errors the problem turned
out to be the vpp section of hardware, the transistor kept blowing.
Check your vpp2 voltage with the "set voltages" option in the
software to make sure it's at 13v. I ended up throwing my
programmer away and buying a picstart plus, but I think my
programmer didnt work reliably because of the way I constructed
it (with veroboard). Anyway goodluck.

I need to use a In Circuit Programme for a production circuit (PIC 16F84).
The picstar plus isn't able to program because on RB6 and RB7 there is a 22
pF capacity versus ground. This two component cut-off the programming
signal (the programming clock of picstart plus is about 100KHz). I try the
YAPP programmer (with 1KHz programming clock) but this is instable in In
circuit programming mode.
Some one can tell me if there is some programmer that is able to do this?
I can buy a big programmer (as ProMate) but it must be able tu resolve this
problem.
TIA.

ProPic 2 ICP is perfect for this job, a in-circuit,
production mode programmer, details at http://www.propic2.com

1. I added 47pf and 56pf to the B6 and B7 pins and my (wisp) programmer
could still program OK.
2. Couldn't you just add a buffer between the programmer an the target?

I am looking for a programmer that will program both 16F84's and 12C508's,
that connects to
The com port of a PC.  It MUST connect to the com port not parrallel.

Thanks for any info,

GRAHAM NORTH

PS  If you could also tell me what software I could use with it I would be
grateful.

I have found and built this unit....

http://www.gbar.dtu.dk/~c888600/newpic.htm

But I substituted some parts and have not made it work yet.  I requires a
driver ( JDM84.EXE ) and I believe it should work with PIP-02.EXE

Don't quote me on the software part yet as I have not got it working.

The JDM84.EXE does detect the presence of the programmer, so that part is
for sure...

Please see our range of programmers at the web page below. They ALL work on
the COM port.

What programmer should I *BUILD* that supports the 16C/F family that is
*free*?


Any help is appreciated,
Andrew

What about the c71?

Thanks,

With the free schematics programmers, i think you will have trouble
getting software free that will do the 71 as well as all the other
devices, but I'm sure someone on this list will come to your rescue with
additional info.

Hi, this might be a dumb question but I cannot help asking it. I wrote my
assemlber program and am trying to upload it to pic16f873. I am using
MPLAB. I found a PIC progammer circuit from web and read ICSP document from
microchip. Looks like I have to build RS232 cable which should be connected
to

TXD(pin3) ------> MCLR'
GND(pin5) -----> VSS
RTS(7)  ---------> RB6
DTR(4) ----------> RB7 through resister
CTS(8) ----------> RB7

this pin configuration is from a circuit but microchip document is just
puzzle to me. After connecting my circuit to serial cable, can I just run
picstar?
could you suggest any starting point?
