I was perusing eBay recently and noticed these old Picstart Programmers going for about $50. Why???!! With an RS232 port and I'm sure limited capability, the only theory I have is as collector's items.

I wrote my own PIC programmer software and use a modified 'noppp' programmer and guess what: it uses the PC parport (just a PCI par port card), oh wait and I made an interface cable and wrote a Raspbery GPIO version. Why not? USB to serial adaptors plenty here too, but USB sucks. The most useful thing about the old PCs is the parport as I/O. It, PIC, is a freaking simple 3 or 2 wire programming system, WHY buy anything? http://panteltje.com/panteltje/pic/index.html all done with that programmer and gpasm in Linux, and without MPlab. I use the PC partport to test all sorts of i2c stuff from displays to GHz chips.

This is beside the point, but to answer why buy anything? Because some people don't have time to screw with it. I could for example buy a PICkit for $50 and be done with it. Or, try to get several hours of free time without the kids bugging me and trying to ignore all the more important stuff I should be doing. But the real question was why anyone is spending so much on such obsolete hardware.

Because some people don't have time to screw with it. See, that is already where you go wrong, Programming does not 'stop' there, now you have your programmer it only STARTS there, And for you to proceed you MUST know how the programming works, read the related documents, else your program will be just like many out there, needless tinkering bloated crap. It is like saying: 'I do not have to know how pliers work, I can just build the cabinet'. There is a 'top down' approach, and in the end it results is an app called 'mama' that sits on the CEO's desk and all he has to know and do is say 'mama I want <whatever>' and it will be done. President's desk too... >I could for example buy a PICkit for $50 and be done with it.

Maybe they like it and it is not so 'obsolete' as you may think OR WANT OTHERS TO THINK Comprendre? And on that tune, show me some code you wrote,

The problem is getting the machine code into the PIC.

I believe I may have posted it here at one time. I almost posted it for you but your attitude is pissing me off and I decided I got nothing to prove.

The problem is getting the machine code into the PIC. So then you do NOT know how to program, do not know the hardware, cannot design the hardware. period. I showed you how I did that. Don't want to learn fine with me.

If you're talking about designing a PIC programmer, yes, I do not care. Sometimes I reinvent the wheel, but in this case there's no value for me to do so. A micro programmer is a tool. In the same way I don't make my own screwdrivers and wrenches, I don't care much to make my own programmer because it's a waste of time. I'd rather design the product that contains the micro, that needs programming. If you're talking about designing a circuit with a ucontroller, yes I can do that. There's industrial products out there with PICs that I was the primary designer on. I did the circuit design and firmware, and customers purchased them. In fact there's an airport somewhere in eastern Europe with our equipment on their radar. You can say any smart-ass thing you want but like I said I got nothing to prove. > period. > I showed you how I did that. > Don't want to learn fine with me. I'm always up for learning something useful, but so far you've only preached to me that I should build my own programmer instead of buying one, or something along those lines.

You know, YOU ask a question, one that shows you did not even do basic research into the subject. if any of you humbug was true you would KNOW how to get and what to get for programmer, and how to make your own. Not knowing how the programmer and programming protocol works means you do not know how to handle the related pins in the design. (In case of in circuit programming it puts restrictions on the design), You are just here to babble about something that you clearly are too <expletive> to even google for for a few minutes, and at the same time saying you need so much to save time... Go buy the f*cking thing from Microchip if you are that much in a hurry and don't bother people who took the time and trouble to provide an alternative and wrote the soft for that. End of discussion as far as i am concerned, find an other victim. Waste of time you are.

I started writing code for and programming PICs for 20 years bud, the CERDIP windowed type and I had a UV eraser. I'm sure you've been doing it longer, but I'm just saying I didn't start yesterday. > if any of you humbug was true you would KNOW how to get and what to get for >programmer, and how to make your own. What do you mean "what to get for programmer"? You think I was asking what I should buy for a programmer? That's not what I was asking. And like I said, it's my choice to not make my own programmer. I got better things to do than to reinvent a perfectly good wheel. > Not knowing how the programmer and programming protocol works means you do not >know how > to handle the related pins in the design. (In case of in circuit programming >it puts restrictions on the design), Hmmm, funny I've been able to get these things to work at all. How on earth did any of the dozens of circuits I put together ever work?? What you're saying is like saying "you have to understand USB protocol to plug a thumb drive in". > You are just here to babble about something that you clearly are too <expletive> to even google for for a few minutes, > and at the same time saying you need so much to save time... Do you even know what the original question was? I'll repeat it for you: I asked why anyone is buying old obsolete PIC programmers for as much as new ones. How does any of what you're saying pertain to this??? > Go buy the f*cking thing from Microchip if you are that much in a hurry > and don't bother people who took the time and trouble to provide an alternative and wrote the soft for that. > End of discussion as far as i am concerned, find an other victim. I'm not buying anything. Again, you obviously didn't read my original post. It had nothing to do with me personally buying anything!!! > Waste of time you are. That's ok. The feeling is mutual.

Life here will be much more pleasant once you put him in your killfile so you won't have to see any of his spew?

I was thinking of another person, also with a 3-letter first name that starts with a J. He's not as bad as Jan apparently but likes to start arguments. Good to know Jan is off his rocker.

I think you would have to buy 2 or 3 of them, so that you can keep working when the first one dies. I find that PICKit3s seem to kill themselves from time to time, I suspect due to some design flaw. I don't think it is ESD, as the circuit that I am programming has never died but multiple PICkits have. No, it is not that the internal PIC has lost its program, although that is also reported to be common - mine still get recognised by the PC and produce waveforms at the programming terminals, just the MCLR voltage is wrong iirc and it reports no target device connected. At one stage I started trying to fault-find one of the PICKIT3s - but I didn't have the time as I was supposed to be working on firmware for someone. Anyway I have a collection of dead PICKit3s to repair one day. No, they are not still covered by http://www.microchip.com/cisar/Home.aspx they want $25 (plus postage + hasle + waiting) to fix them, so at this time buying more new ones from the distributor was a better option.

At a guess: one market for them would be people who want/need to program certain legacy PIC chips that require a parallel interface and (I think) a relatively high programming voltage. The modern PIC chips use a "very few pins" serial programming interface, and the modern batch of inexpensive chip programmers often do not implement the parallal programming algorithm for PIC. Another option, of course, would be to disassemble the code for the older PICs, and port it to a modern PIC chip. However, I suspect that this may well be a non-trivial task in many cases - the chip pinouts and the peripheral sets are different enough to require significant re-engineering. So, for people who are repairing older hardware that uses the legacy PIC chips, or building "clones" of these devices, it may simply be cheapest and least-hassle to buy a tube of the old parts, and an old Picstart.

Or, more generously, how much of your time would you SPEND $50 to *save*? Cables are reasonably mindless undertakings. Why would anyone *buy* a cable when they could MAKE one for far less money? I.e., if you have a *need*, then YOU decide what the most effective way to satisfy that need is likely to be. Build vs. Buy? Or, use something *other* than a PIC?? I've got an old Compaq Portable 386 (lunchbox) that I use as a "two slot ISA machine" for some legacy tools that I support. It harkens from the days of 20MB 5" disk drives. I can either try to find a tiny IDE drive that its' BIOS will recognize -- or, modify its BIOS to support a "less tiny" (but still incredibly tiny!) disk drive. [I chose the latter option] Should I replace the EPROMs holding the BIOS with FLASH devices? Or, erase/reprogram them directly -- which requires a UV light source and a PROM programmer. Will the PROM programmer have a USB interface? Serial? Parallel? Ethernet? etc. How far down this list of prerequisites do you travel before you consider it "not worth your effort"? [BTW, I keep a slew of old "development boards" in the garage for just that sort of legacy problem solving]

I can hack together a cable, circuit board, FPGA, etc. to tackle a problem I'm faced with. But, if I can *buy* a solution -- esp for very few dollars (which is where "50" fits on the scale) -- then its almost always a smarter way to use my time!

THANK YOU. Now, will someone please try to explain that to Jan. Or, maybe don't as I have a feeling it's a waste of time.

Now, will someone please try to explain that to Jan. Or, maybe > don't as I have a feeling it's a waste of time. People have their own motivations behind *their* decisions. I routinely repair LCD monitors. If you look at the *time* required of me to do so, it's silly -- I should spend that hour as billable time and use the monies received to *buy* a new monitor! But, it's a no-brainer activity, for me, and justifies itself as: - diverting scrap from landfills - "simple" problem solving (like putting together a jigsaw puzzle -- no effort required there!) Likewise, doing periodic maintenance on the cars. At $90/hour for the dealer's time, its cheaper to let *him* do everything! OTOH, if I have to put in an hour of my time to drive to/from the dealership and have to sit in a waiting room while he does the work, then I've not saved any (billable) time. And, if I put *my* head under the hood, *I* can see what's really happening, there, instead of trusting to a grease monkey to spot issues before they become "problems".

Now, will someone please try to explain that to Jan. Or, maybe don't as I have a feeling it's a waste of time. It is a waste of time. The guy has some pretty obvious issues.
