Sad to see parport adapters go.
<Haohmaru>
hm?
<PaulFertser>
Haohmaru: are you not subscribed to the mailing list?
<Haohmaru>
i'm allergic to mailing lists
<Haohmaru>
i'm about IRC and phpbb-like forums
<PaulFertser>
OK
<Haohmaru>
i've had to look thru websites that have lists of mails, and it looks like a forum or a conversation log at first sight, but it's actually terribly difficult to follow and/or find what you want
<Haohmaru>
i've had to do that several times in the past, for different reasons
<Haohmaru>
x_x
<Haohmaru>
yet so many people like them, so it must be my fault
<Haohmaru>
and maybe about almost 20 years ago i needed help with a very particular SDK, the people on the forum couldn't answer my questions and redirected me to the place where the more knowlagable are - it was "yahoo groups" which now i understand has been a mailing list thing
<Haohmaru>
i clicked and clacked thru it, registered, blahblah, managed to get on there and talk to those people, but it was weird and inconvenient
<Haohmaru>
maybe the point of mailing lists is to raise the bar so people like me are discouraged from intruding ;P~
<Haohmaru>
what happened to parallel ports?

Haohmaru: I can't stand mailing lists either fwiw for me it's irc alone. Even forums are not making sense
<Haohmaru>
yeah there are some new ones like this "discourse" kind which i hate

Haohmaru: when was the last time you used a PC LPT port?
rigid has joined #openocd
<Haohmaru>
parallel port? D-SUB-muchos_pins?
<Haohmaru>
i flashed some atmegas with it at home
<PaulFertser>
You can flash atmegas with RS-232 port as well.

don't these have a higher voltage?
<PaulFertser>
Haohmaru: they do but not that a zener + resistor can't handle that.
<Haohmaru>
the parallel port scheme required just a few optional series resistors
<PaulFertser>
Yes but it's not like 3 zeners and 4 resistors is much.
<Haohmaru>
well, i needed a programmer, had no clue of anything, someone asked me if i have a parallel port, i said "yes" ...
<PaulFertser>
:)
<Haohmaru>
afterwards i bought an olimex avrisp2 clone
<Haohmaru>
because i needed xmega PDI

PaulFertser, is parallel port still really a thing, maybe I underestimated the user base of parallel ports :D
<PaulFertser>
zapb_: I do not really know but people on the mailing list sound convincing.
<PaulFertser>
:)
<zapb_>
PaulFertser, to me, it sounds more like nostalgia than real necessity of parallel ports adapters :D
<zapb_>
PaulFertser, do you use parallel ports adapters?
<PaulFertser>
zapb_: I personally do not but I also do not develop any hardware and hardly use OpenOCD at all :(
<zapb_>
PaulFertser, not working with embedded devices anymore?
<PaulFertser>
zapb_: just occassionally
<borneoa___>
Last time I used it was ~11 years ago. Laptops do not have it anymore, but desktop can easily get one on a cheap PCIe card. I think it's the simpler gpio-like interface people can get on a PC and bitbanging it runs faster than a usb-gpio.
<borneoa___>
zapb_: I see you dropped 3 adapters. Apart from parport, the other two looks really obsoleted and could be dropped.
<zapb_>
borneoa___, I find it hard to believe that a significant number of professional embedded developers use parport adapters for their work :D
<zapb_>
borneoa___, I played with the build system of OpenOCD and then stumble upon the parport driver and to me it is totally unclear if this driver still works on Windows or not, for example
<zapb_>
From what I find on "the internet", the giveio.sys driver is not supported on 64-bit systems anymore
<borneoa___>
zapb_: not professional, but hobbyist and retro-computing enthusiastic will not really care about performance. Look at the huge buzz around z80 CPU getting out of production lest weeks and the amount of people going to resurrect it in FPGA or SW emulators.
<PaulFertser>
I'm not sure but probably my parents still sometimes print on an LJ-5L connected with a USB to parport adapter.
<borneoa___>
PaulFertser: Humm, I think it's 5v, yes
<PaulFertser>
So makes it not so suitable for most modern JTAG-capable devices.
<borneoa___>
I think most stm32 have 5V tolerant gpios, while still being powered at 3V3. But for the most advanced devices, 5V is sure death!
<borneoa___>
Also the latest stm32 should not be anymore 5V tolerant. Automotive devices should be much more robust, but I don't have experience there
<zapb_>
borneoa___, I understand that there are some users that like (for whatever reason) parallel port adapters but it should not block development

Personally I don't see too much burden with them. I dropped zy1000 and eice (was that the name?) because we got really nightmare to go ahead supporting them. I'm looking to remove the dependency on libftdi on the last 2 driver that use it. But I don't feel so much pressure from the parport, yet
<zapb_>
borneoa___, well, at least we have an unclear status on Windows and no documentation at all. Given the large user base (larger than expected ;)) dropping parport entirely may be excessive but maybe the Windows support?
<zapb_>
borneoa___, I would like to test all my for regressions and I don't find any documentation how to setup OpenOCD on Windows with parport enabled
<zapb_>
-> all my changes
bvernoux has quit [Quit: Leaving]
<borneoa___>
Yep, I got surprised too for the large user base :-)
<borneoa___>
It was aice that I've dropped, not eice
<borneoa___>
Also never used it in Windows, cannot help there. Probably obsoleting Windows support could be ok. And also gw16912 and amtjtagaccel.
<borneoa___>
Maybe a reply on the mailing list with such proposal, before wasting time on coding..
<zapb_>
borneoa___, okay, if we don't find Windows users or help for setup parport on Windows we mark it deprecated?
