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. Later, BAJ

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?

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 ;-)

(Could be wrong... often am ;-) > 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. BAJ

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 ; Parallel Port Pin .--------. Switch /o----- GND ; (2) D0 ---{13 4}----------o/ o----- +12V ; (3) D1 ---{12 14}--------. ; | 5 16}-+-%%%%-`--- +5V ; `----+---' | 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?

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 antti ---------------------------------------------------------- -- Antti Lukats Silicon Studio -- -- .....sisKILLspam@spam@rasi.lr.ttu.ee PO Box 3500 -- -- ftp://rasi.lr.ttu.ee/pub/sis Tallinn EE0001 -- -- http://rasi.lr.ttu.ee/~sis Estonia -- ----------------------------------------------------------

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). > 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.

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.

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...

Very convenient! There are many people supplying 16C84 only programmers cheaply, @spam@donmckKILLspamtbsa.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.

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. - Tom PSBS: If you are into horses, click on the Horse pic that looks like Mr. Ed ;-) At 02:24 PM 12/16/97 +0100, you wrote: {Quote hidden}> Since there are no programmers for the complete > range of pics on the Amiga platform, i decided to > write it.

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 Rafael Pinto

There is something wrong with the hardware of your ProPic. Double check the wiring.

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. http://www.needhams.com http://www.digikey.com Cheers, Bob

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... Fred. fred.hatfieldspamBeGonesstar.com New Orleans

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.

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

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. > Other thing: to verify the contents of program memory, they use CTS to > read from the 16C84.

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. -- Cheers, Paul B.

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

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.

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 > internal (on the FGPA etc.), but not always. 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. Eric http://www.brouhaha.com/~eric/pic/ http://www.brouhaha.com/~eric/scenix/

Interesting suggestion. >> Some LSI circuits may include them internal (on the FGPA etc.), but >> not always. > I've never heard of such a thing. Can you cite a reference? 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". > 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). 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. -- Cheers, Paul B.

Can you cite a reference? 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.)

Look up a NS16550[A] datasheet / register level programming. The 12V method works only for the 84 as far as I can tell. > Other thing: > to verify the contents of program memory, they use CTS to read from the > 16C84.

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. Peter

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. > For embedded apps, it would be quite nice.

Often the manufacturers choose to make multiple variants with different tradeoffs.

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.

But 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 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?

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.

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?

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? --chunhee
