:?:
for clarity since the poll questions seem lacking by some..
1. Do you ONLY use your Dragon for either/or JTAG/ISP/DeBUG Wire AND typically only have a flat ribbon cable protruding from the Dragon for your intended use AND probably do not intend on using the "other" stuff (as you may not want to AND/OR you may have other means to do the "other" stuff with something else).
OR
2. Do you ONLY use the other "stuff" (HVSP/DIP SOCKETS) on the Dragon and thus took the time to populate the dip sockets and so forth for your intended use. For this reason you need access to the "other" stuff on the pcb.
OR
3. Do you use both 1 AND 2?

hope that helps..if not and the poll is deemed worthless..ok..dislike polls too but was just curious.

I went with the top option but that's because I've got STK500's - surely this is really asking - do you have other tools to do the other things you don't use the Dragon for?

after reading the other dragon thrashing thread..was kind of curious how many Dragon users actually use the Dragon HSVP / DIP Socket stuff.

When I had an AVRDragon and was using it almost exclusively, I only used the ISP programmer aspects of the thing.

I did, however, try DebugWire programming. But I could't seem to get it to work consistantly, though, I know others have...

aside from the v1 electrical issues..it seems one of the big gripes about the Dragon was the lack of a proper case.. The JTAGICE and MKISP did have a case..the STK500 did not...one of the big differences between these tools besides the case/no case , was whether they had HVSP/ Dip sockets.
The Dragon appeared to be an attempt of combining most of the functionality of all these devices JTAG/ISP/DEBUG WIRE/STK500 HVSP ..BUT that merging complicated the mechanical design to include a low cost case for the Dragon IMHO. Reviewing the Dragon threads ...Dragon users have been very creative in trying to find an suitable lair for their Dragon, depending on how each user was going to use the Dragon.
Maybe the poll can help illuminate a solution for anyone sleeping at a CAD station. :idea:

The poll options are not really very good. Some might use only JTAG and not ISP. Some might use HVSP but not use the dip socket. I can't see that the options the way that they are can give very much useful info.

I have mine permanently wired for HV programming of ATTinyx5s using an onboard ZIF socket, as occasionally I have to program 48 of them that have reset disabled. However most of the time I use it for JTAG flashing of external MCUs. I avoid on-board programming of larger MCUs, it's a pain to rewire and I don't want to stress the power supply.

I use mine exclusively for ISP. I might just as well have gotten an AVRISP MK2, but Digi-Key had an STK500/dragon twofer deal a couple of years ago and it seemed like a neat tool. Abused, but not fried yet.

Same as clawson: I use it only for JTAG/debugWire, since my AVRs are on STK-500's. (When/if this changes and the AVRs are on target boards then things might be different.)

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

I just bought a Dragon to JTAG program the XPLAIN boards that I just bought, to try out the xmega, to see if I want to apply them in a new product, which I probably will 8-)

I put a 40 pin ZIF socket on it. I have no other programmer for debudWire, so it is used 100% for that purpose, usually off the Dragon itself.

I do use it to program ISP and JTAG on and off the Dragon PCB.

I occasionally use it for HVPP when I made a chip brain-dead. Otherwise there are too many wires to hook up for frequent usage.

I have a JTAG-ICE programmer that I almost never use any more. I have an AVRISP-MkII that I frequently use, but the fact the the Dragon supplies its own power to the chip is a real good feature. I just wish it also included a clock signal that I could wire to the appropriate pin on the chip.

What a waste of money buying a Dragon and only use it for programming.

I never used a Dragon for HV programming so I don't use ALL of it's functions?? There should be another option on the poll.

The Dragon is STRICTLY used for OCD here.

Where is this major "waste of money" ? There is only a $15.00 difference between the Dragon and the AVRISP mk2. And with the Dragon, if one needs more options in the future then its already there with the Dragon , versus the MK2, thats more limited. Help me understand

Exactly, $15 wasted. For programming only the Dragon is not as robust as an AVRISP which can be thrown around on the bench or inside a tool box and still work.

I would encourage everyone to have at least a Dragon but use it for what is mainly intented to do, debugging.

So which box do I tick if I use the Dragon for debug only?
