2017-11-01T00:01:25 < englishman> this is just for boring uart but i have another ftdi cable acting as a bed of nails test jig with pydongs running it
2017-11-01T00:06:39 < karlp> I mean, the moulded cables are nice, but if you're cheap, cp210x dongles and usb extension cables are ~2-3$ on ali and co
2017-11-01T00:11:41 < qyx> LT3652 works nicely
2017-11-01T00:11:56 < qyx> except that the thing heats a bit when charging at 2A

2017-11-01T00:55:34 < renn0xtk9> I do 3 time cat /dev/ttyACM0
2017-11-01T00:55:39 < renn0xtk9> one time it stays blank
2017-11-01T00:55:47 < renn0xtk9> one time i can see my data flowing
2017-11-01T00:55:59 < renn0xtk9> one time it says cat: /dev/ttyACM0: Device or resource busy
2017-11-01T01:00:15 < karlp> did you pay attention when we said earlier not to try and cat things to and from the device file unless you're wizard?
2017-11-01T01:00:34 < karlp> that why lies insanity and far more poking with stty than you really wanted to know

2017-11-01T01:06:50 < sync> haha
2017-11-01T01:07:06 < sync> I usually have ok luck with catting out of the file
2017-11-01T01:07:07 < renn0xtk9> karlp what do you mean exactly
2017-11-01T01:07:44 < renn0xtk9> what should I do ?
2017-11-01T01:07:59 < karlp> use picocom/minicom or similar, you'll be far more satisfied with the behaviours

2017-11-01T01:08:31 < renn0xtk9> right I will try it soon
2017-11-01T01:08:43 < renn0xtk9> but If I have cat: /dev/ttyACM0: Device or resource busy
2017-11-01T01:08:51 < karlp> what part aren't you following?
2017-11-01T01:08:59 < renn0xtk9> I would be surprised if the problem comes from the host side
2017-11-01T01:09:28 < karlp> then go solve it.
2017-11-01T01:09:33 < karlp> either ask for help or don't
2017-11-01T01:09:52 < renn0xtk9> karlp , yes that is the point of my question ;) if anyone has a clue on how to solve it
2017-11-01T01:11:06 < renn0xtk9> Looking on the web I see 10^10^10 users making things over the serial port and catting, and everything works fine for them. So when I trying the comport with an mcu and it does not fully work the first thing I suspect is not the catting..
2017-11-01T01:11:30 < renn0xtk9> It is like if you develop your own software, it crashes and then you say "that must be the OS"
2017-11-01T01:11:32 < karlp> the thing with catting is that it works right up until it doesn't
2017-11-01T01:11:57 < karlp> and you _must_ be using stty and friends to set up the port before you try using cat.
2017-11-01T01:12:45 < renn0xtk9> cat: /dev/ttyACM0: Device or resource busy < " I suspect Device or ressource busy here comes down from tht OS not the cat
2017-11-01T01:14:51 < renn0xtk9> karlp FYI https://paste.opensuse.org/28523540
2017-11-01T01:15:17 < karlp> great, but now you're going to get a consistent answers from cat.
2017-11-01T01:15:26 < karlp> earlier, remember, how it only gave you that sometimes?
2017-11-01T01:15:31 < karlp> and sometimes it returned immediately?
2017-11-01T01:17:02 < renn0xtk9> but the problem is exactly the same with cat or picocom, I have to initiate the connection with .e.g. "echo "t" >>/dev/ttyACM0" for it to work
2017-11-01T01:17:14 < renn0xtk9> and that problem must come from the STM32
2017-11-01T01:17:36 < karlp> clearly you've not done a very good job of followingg the st example code then :)
2017-11-01T01:17:53 < renn0xtk9> well I copy paste their code
2017-11-01T01:17:59 < renn0xtk9> and to say more on that
2017-11-01T01:18:09 < renn0xtk9> there are actually two examples
2017-11-01T01:18:11 < karlp> that was, what, 8 hours ago?
2017-11-01T01:18:33 < renn0xtk9> I don't do only this, inbetween I have been away;)
2017-11-01T01:18:52 < renn0xtk9> one examples is a I said a not working - not example (since they don't make use)
2017-11-01T01:19:24 < renn0xtk9> the second is with the loopback, which is probably the one dong was talking about when he though i knew what I was talking about
2017-11-01T01:19:39 < karlp> (protip, he does)
2017-11-01T01:20:06 < renn0xtk9> as a matter of fact he was talking about example 2 while I was working on 1 and I mentionned it ,
2017-11-01T01:20:39 < renn0xtk9> it did not read what i was writing he was to much occupied wrintg "fucking idiot fucking fudkcd duckfuck "
2017-11-01T01:21:14 < renn0xtk9> second, if you want to prove me you are of superior intelligence you may welll give a hint on were it come from since

2017-11-01T01:21:34 < renn0xtk9> 1) you picocom storry was not a particulary a non wasting time stuff
2017-11-01T01:22:12 < renn0xtk9> 2)only achievement you claim so far is copy pasting ST examples successfuuly..
2017-11-01T01:22:18 < Laurenceb_> sup trollz
2017-11-01T01:22:33 < karlp> no. I'm saying you were going to continually run into problems if you just try echo and cat with the device files.
2017-11-01T01:22:47 < Laurenceb_> meow
2017-11-01T01:22:49 < karlp> I would imagine you're not handling control requests early on in your usb init
2017-11-01T01:23:06 < karlp> likely as a result of not following the examples :)
2017-11-01T01:25:02 < renn0xtk9> well ;) there is virtually only a few line chaing with regards to the examples and that is where I blink a LED

2017-11-01T01:25:30 < renn0xtk9> therefore very unlikely that I screw up the USB request handling from within the main
2017-11-01T01:26:06 < renn0xtk9> moreover googling I have already found 3-4 thread (unsolved) of issue with STM32 and serial
2017-11-01T01:26:21 < renn0xtk9> therefore I would more suspect ST to not be fully linux compliant
2017-11-01T01:27:05 < renn0xtk9> well I know the whole virtual com port principle is already a hack in itslef but still...
2017-11-01T01:27:59 < renn0xtk9> and btw Laurenceb_ who's trolling who, I don't insult anybody so far, they did...
2017-11-01T01:28:42 < karlp> not really a hack, not a great use of usb, but a very well documented, standardized usage of usb.
2017-11-01T01:29:07 < Laurenceb_> renn0xtk9: everyone is trolling everyone
2017-11-01T01:29:15 < Laurenceb_> see emdrive
2017-11-01T01:30:01 < upgrdman> looking for a way to capture webcam video with java. "JavaCV works well" ... the fucking Jar is >200MB lol
2017-11-01T01:30:37 < renn0xtk9> can it be somewhere that the STM32 is asking blocking access to /dev/ttyACM0 file
2017-11-01T01:30:58 < renn0xtk9> which would explain why device or ressource busy
2017-11-01T01:31:26 < renn0xtk9> and then when echo "t" >>/dev/ttyACM0 it would somehow stop the blocking access
2017-11-01T01:31:45 < karlp> the stm32 doesn't ask for anything, usb is host drive.
2017-11-01T01:32:38 < renn0xtk9> yeah but I don't remember exactly now but when you write you URB that is a parameter
2017-11-01T01:33:01 < renn0xtk9> maybe this one is badly defined, at lesat for the first one that will initiate communitcation
2017-11-01T01:33:02 < karlp> yes, but that's on the host side
2017-11-01T01:33:21 < karlp> no, if you somehow need to send a char to be able to start receiving chars, you've got a busted model
2017-11-01T01:33:24 < renn0xtk9> yeah true the driver
2017-11-01T01:33:33 < Laurenceb_> <upgrdman> so is CubeMX
2017-11-01T01:33:51 < upgrdman> Laurenceb_, is PubeMX java trash?
2017-11-01T01:33:57 < sync> yes
2017-11-01T01:34:00 < upgrdman> o lol
2017-11-01T01:34:03 < upgrdman> cool
2017-11-01T01:34:16 < renn0xtk9> never blame host or material, before code is provem 100.0% correct ^^
2017-11-01T01:34:33 < karlp> yes, it's very unlikely you have a host issue.
2017-11-01T01:35:04 < renn0xtk9> load of thread I read suggest bad interface desription on stm32 side
2017-11-01T01:35:12 < renn0xtk9> like it try to present itself as a modem
2017-11-01T01:35:38 < renn0xtk9> but maybe somehow the desciption is wrong
2017-11-01T01:35:45 < karlp> I'd suggest the statemachine of how you setup transfers, assuming you copied the descriptors from somewhere working and didn't try hacking them to make them "special"
2017-11-01T01:37:01 < renn0xtk9> what do you mean statemachine of how you setup transfers
2017-11-01T01:40:09 < renn0xtk9> right got to go

2017-11-01T02:47:31 < Ultrasauce> upgrdman I messed with it a few years ago, it was undergoing some growing pains with a major api change at the time and performance was an issue
2017-11-01T02:47:40 < Ultrasauce> it has cuda support now though which is pretty dank
2017-11-01T02:49:19 < dongs> "open" shit going through API change, what a fucking shocker
2017-11-01T02:49:55 < dongs> fuck existing code, opensores faggots have nothing better to do than keep rewriting their shit every time version 0.1 of freefaggotlib gets released right?
2017-11-01T02:50:06 < Ultrasauce> well it was moving from c to c++
2017-11-01T02:50:12 < Ultrasauce> which is necessarily a clusterfuck
2017-11-01T02:50:18 < dongs> so from being somewhat usable to complete trash
2017-11-01T02:50:26 < dongs> does it really only have gay++ api now?
2017-11-01T02:50:31 < Ultrasauce> idk
2017-11-01T02:51:03 < Ultrasauce> looks like they successfully generalized it to having different language interfaces
2017-11-01T02:51:42 < Ultrasauce> and it does ML stuff now I guess, neat
2017-11-01T02:52:05 < upgrdman> ya theres JavaCV for us java fags

2017-11-01T02:58:25 < Laurenceb_> I was watching some demos of OpenCV the other day
2017-11-01T02:58:47 < englishman> opencv seems ok but i wonder why they have all this lunix input/output stuff as well
2017-11-01T02:58:50 < Laurenceb_> I'd actually say that the neural network object recognition is approaching human levels
2017-11-01T02:59:28 < Laurenceb_> it just looks shit because it doesnt have any other info
2017-11-01T02:59:45 < englishman> upgrdman, what do you want to do
2017-11-01T02:59:48 < englishman> shit like this exists https://cloud.google.com/vision/
2017-11-01T02:59:50 < Laurenceb_> it needs spacial/temporal/dynamic/contextual filtering
2017-11-01T03:00:04 < Laurenceb_> with all that added it might be human level
2017-11-01T03:00:22 < dongs> need to train it wiht as many dickpics as possible

2017-11-01T03:01:21 < upgrdman> englishman, i actually dont have any need right now. it just seems like their webcam api for java might be the easiest way to capture video for my telemetry viewer program, and i figure that dicking with opencv later on might be nice. learning opengl really kinda expanded my capabilities more than i thought it would, and i feel like CV could have similar results

2017-11-01T04:24:32 < branjb> tuesday was a bad day to recieve packages
2017-11-01T04:24:39 < branjb> some trick or treat fags stole my stepper drivers
2017-11-01T04:26:53 < dongs> Lol
2017-11-01T04:27:01 < Syke> so in Your stone-aged country having temperature measured with Freedom units, parcel service leaves packages on door steps?
2017-11-01T04:27:22 < Ultrasauce> wait is there some utopia where couriers don't suck?
2017-11-01T04:27:36 < branjb> amazon uses random people to deliver packages, so no mailbox keys
2017-11-01T04:27:58 < Syke> I have heard systems, where parcels are usually delivered to your nearest convenient snackbar shop
2017-11-01T04:30:25 < englishman> my random amazon dudes have all been pretty legit
2017-11-01T04:31:25 < branjb> mine too
2017-11-01T04:31:31 < branjb> i didn't get home till 7
2017-11-01T04:31:57 < branjb> 99% sure some tricker treater just scored some free stepper drivers
2017-11-01T04:33:30 < englishman> heres hoping he chokes to death on them ðŸº

2017-11-01T04:37:01 < dongs> yes, in japan they will just bring shit into my office and leave it inside
2017-11-01T04:37:07 < dongs> even while im out
2017-11-01T04:37:17 < branjb> in japan they probably give you a complimentry foot massage with each delivery

2017-11-01T09:03:21 < ohsix> Thorn: not exactly, but yes
2017-11-01T09:03:45 < ohsix> you need to scale the inputs to them somehow tho
2017-11-01T09:04:28 < ohsix> or you can use a different sample rate with the other and sample the low order bits faster, still not 16 but you get most of the benefit
2017-11-01T09:06:03 < ohsix> have you guys seen this stuff? https://www.3m.com/3M/en_US/company-us/all-3m-products/~/3M-Electrically-Conductive-Adhesive-Transfer-Tape-9703

2017-11-01T09:07:34 < ReadErr> trying to get small smd parts off sticky shit
2017-11-01T09:07:40 < ReadErr> wouldnt be fun
2017-11-01T09:08:16 < ohsix> heh
2017-11-01T09:08:52 < ohsix> i think you're missing the thing, it's not for resistors and shit
2017-11-01T09:09:12 < ohsix> though i suppose you could do that, but you'd probably be wasting your time
2017-11-01T09:09:39 < ohsix> after you toast a flight controller you can put another chip on it without rework ;]
2017-11-01T09:10:25 < ohsix> or if you have one of those breakouts for fine pitched cables, you can keep it unpopulated with the connectors, and stick the tape, or tapes onto part of the strip
2017-11-01T09:10:30 < Thorn> why different sample rates?
2017-11-01T09:11:31 < ReadErr> ohsix: its just a big list of products
2017-11-01T09:11:35 < ohsix> it's the only thing i could think of to trade off, you could sample any of the 8 or 12 bits faster
2017-11-01T09:11:38 < ReadErr> when i click it
2017-11-01T09:12:01 < ohsix> ah, sec

2017-11-01T09:16:40 < ohsix> keep the vref within 500mv of the control signal and you're supersampling an area of interest projected onto the other

2017-11-01T13:44:55 < zyp> haha
2017-11-01T13:46:05 < karlp> i guess it must be from watching an elce video on emmc/ufs/nvme stacks
2017-11-01T13:52:20 < zyp> any crypto pros here?
2017-11-01T13:53:46 < zyp> I'm looking at some shit that's using AES for generating authentication tokens, and I wonder if it's as insecure as it looks
2017-11-01T13:56:28 < zyp> there's a server issuing challenge tokens, to talk to the server the client must calculate a key token corresponding to the current challenge
2017-11-01T13:57:20 < karlp> sounds like someone rolled their own crypto from pieces.
2017-11-01T13:57:36 < karlp> and what, everyone has the same shared AES key?
2017-11-01T13:57:39 < zyp> the key token is calculated by encrypting the challenge token
2017-11-01T13:57:53 < zyp> yes
2017-11-01T13:57:57 < karlp> soudns dumb
2017-11-01T13:58:24 < karlp> no way of revoking bad clients, no way of separating clients
2017-11-01T13:58:27 * karlp shrugs
2017-11-01T13:58:31 < karlp> not a crypto guy
2017-11-01T13:58:49 < karlp> is this just to get a secure channel to sign up for a unique per client channel?
2017-11-01T13:59:05 < zyp> it's using AES_CBC with a 128-bit configured key and a fixed IV
2017-11-01T13:59:31 < zyp> the fixed IV essentially reduces security to that of AES ECB as far as I can tell
2017-11-01T14:00:35 < zyp> karlp, no, but multi-client is not a concern
2017-11-01T14:01:09 < zyp> this is used to authenticate commands issued to the server
2017-11-01T14:01:30 < karlp> yeah, but you can't auth who they came from, just that they came freom _someone_ who had the master key.
2017-11-01T14:01:50 < zyp> yes, that's not a problem
2017-11-01T14:02:05 < karlp> ok then :)
2017-11-01T14:02:18 < zyp> this is some IoT bullshit
2017-11-01T14:03:05 < zyp> server doesn't have a concept of users, it just distinguishes between allowed to send commands or not
2017-11-01T14:03:21 < zyp> anyway
2017-11-01T14:04:13 < zyp> the thing is, the communication itself is not encrypted, the key token is just added to the command packet
2017-11-01T14:04:39 < zyp> and all the communication happens over multicast, so any network node can observe it
2017-11-01T14:06:01 < zyp> in other words, with access to the network, you can observe plaintext/ciphertext pairs, and the IV is known
2017-11-01T14:06:24 < zyp> so I'm wondering how feasible it would be to reverse the key from this
2017-11-01T14:08:22 < karlp> sounds totally broken
2017-11-01T14:08:31 < zyp> depending on the client, it might also be possible to impersonate the server and talk to a client that knows the key, giving you ciphertext for known plaintext
2017-11-01T14:08:50 < zyp> well
2017-11-01T14:09:27 < zyp> as far as I can tell, using a fixed IV just reduces the security to that of AES ECB
2017-11-01T14:09:29 < karlp> it soundsd like someone just threw some crypto primitives at it and said, "ok, secure now"
2017-11-01T14:09:50 < zyp> haha, true
2017-11-01T14:10:27 < zyp> well, the biggest issue is that as far as I can tell there's nothing preventing key reuse
2017-11-01T14:10:58 < zyp> the key is updated every few seconds, but I haven't seen anything that says a key token can only be used once
2017-11-01T14:11:46 < zyp> so you could just monitor for commands and as soon as you see one, just reuse the same token for more commands before it's changed
2017-11-01T14:12:26 < zyp> but I might be wrong on this, it would be natural to issue a new challenge as soon as one command is received

2017-11-01T19:32:31 < karlp> yeah, but not a surprise that they're a nuisance :)
2017-11-01T19:32:38 < karlp> they're in lots of cities
2017-11-01T19:39:36 < Steffanx> I dont really give a damn englishman. I do weed, nor prostitution. And i hate drunk.
2017-11-01T19:39:40 < Steffanx> *dont do
2017-11-01T19:39:40 < Steffanx> lol
2017-11-01T19:39:41 < Steffanx> whops
2017-11-01T19:41:33 < Steffanx> nein meinherr superbia
2017-11-01T19:42:52 < BrainDamage> seems to me the main problem is the cohabitation of the residents with the tourists, not the activity itself
2017-11-01T19:43:45 < BrainDamage> we have sorta similar problems here, because of so many tourists in some places like venice the houses are getting all rented
2017-11-01T19:44:05 < BrainDamage> and the residents driven off by the insane prices
2017-11-01T19:44:32 < BrainDamage> actually the city has a strong industrial economy
2017-11-01T19:44:44 < BrainDamage> there's one of the largest petrolchemical plants of the country near it
2017-11-01T19:45:03 < BrainDamage> also, without residents the services die
2017-11-01T19:45:12 < BrainDamage> bars, supermarkets, etc close
2017-11-01T19:45:27 < BrainDamage> you end up only with seasonal services during tourism peaks
2017-11-01T19:45:38 < BrainDamage> and I'm not speaking theoretically, it's already happening
2017-11-01T19:45:55 < BrainDamage> i have a friend that lives there and complains about this stuff regularry
2017-11-01T19:47:10 < BrainDamage> there is no other venice

2017-11-01T22:14:31 < Steffanx> At work we had some (dont remember which ones) that drifted nicely over temperature. "Freeze" it from 20 to -20 and let it heat back up to to +20 and it would be totally fucked
2017-11-01T22:15:02 < Laurenceb> it looks like the datasheet is kind of telling the truth
2017-11-01T22:15:08 < Laurenceb> lsm6 is very low noise
2017-11-01T22:15:23 < Laurenceb> hard to get away from enough ambient vibration to screw the noise floor
2017-11-01T22:17:35 < Steffanx> you realllly care about noise that much?
2017-11-01T22:17:56 < Steffanx> i mean wouldnt the vibration of the car be much higher than this noise anyway?
2017-11-01T22:18:18 < Laurenceb> yeah but its nice to have low noise for precision

2017-11-01T22:21:39 < vampi-the-frog> I wonder if it's possible to train a neural network to see what's on topic and what's off topic and just feed in data from this channel for training
2017-11-01T22:22:09 < BrainDamage> it'd have way too little input for ontopic material to have sufficient training
2017-11-01T22:23:19 < Steffanx> Bye vampi-the-frog.
2017-11-01T22:23:52 < vampi-the-frog> well I could feed in data from other channels which are more on topic
2017-11-01T22:24:17 < Steffanx> but your neural network has to learn what the topic is
2017-11-01T22:24:27 < vampi-the-frog> well, there are other stm32 channels

2017-11-01T22:25:47 < vampi-the-frog> meh about 60% on topic maybe
2017-11-01T22:26:10 < vampi-the-frog> I'm not on topic now
2017-11-01T22:26:22 < vampi-the-frog> most of what I say is either STM32 stuff or stuff about being off topic
2017-11-01T22:27:40 < Steffanx> So stop that last part and you'll be 100% on topic. Win-win for all of us :)

2017-11-01T22:29:23 < ohsix> there's a thing with irc channels, if there isn't enough turnover then everyone ends up basically knowing the subject, and not having to communicate it to people that are around them
2017-11-01T22:29:26 < ohsix> happens in real life too
2017-11-01T22:29:33 < ohsix> what you want is more turnover
2017-11-01T22:29:58 < ohsix> otherwise it is just people with a common interest
2017-11-01T22:30:28 < ohsix> it takes work for turnover, and if there aren't people looking for help or to learn or talk about it, you have an existential problem

2017-11-01T22:50:50 < Steffanx> + unknown word user
2017-11-01T22:50:54 < Ultrasauce> I think that was a pretty friendly statement
2017-11-01T22:51:06 < vampi-the-frog> it somehow can't get enough access to read the HID descriptors and some other descriptors
2017-11-01T22:51:06 < Ultrasauce> if you choose to interpret it otherwise, what does that say about your own state?
2017-11-01T22:51:09 < ohsix> there is a friendly reading, but i wasn't really speaking broadly
2017-11-01T22:51:09 < vampi-the-frog> even when run as root
2017-11-01T22:51:09 < Steffanx> My sarcasm detector detected something else.
2017-11-01T22:51:17 < vampi-the-frog> but it works fine on linux if you run it as root
2017-11-01T22:51:34 < vampi-the-frog> if you run as non-root you won't get the HID descriptors and it will be incomplete information

2017-11-01T22:51:48 < Steffanx> My own state wasnt friendly, Ultrasauce. Never was probably.
2017-11-01T22:51:49 < ohsix> if you want on topic chats you need lots of people who know less, thus turnover, thus telling people who otherwise wouldn't know how the $subject is relevant to them, and where to ask
2017-11-01T22:52:05 < Steffanx> nah, i dont use lunix much vampi-the-frog
2017-11-01T22:52:10 < Ultrasauce> I am offended by the mere notion
2017-11-01T22:52:12 < ohsix> and even then it's a ratio, people familiar with the subject will talk amongst themselves

2017-11-01T23:14:00 < ohsix> all this misreading today; i don't think it's a bad thing, it's just mysterious
2017-11-01T23:14:09 < ohsix> they phoned and said they'd be delayed so we're all speculating
2017-11-01T23:15:08 < ohsix> when it's a bunch of dudes all the thought goes to something vagina specific
2017-11-01T23:15:33 < ohsix> but it could be something marketed to women for other women things, but nobody in the room can even conceive of much else, it is funny
2017-11-01T23:15:50 < ohsix> now there is risk irc is seen, bbl
2017-11-01T23:17:42 < ohsix> also nca/nda being signed, i'm never party to them but it's kind of a dick move to live tweet ;]

2017-11-02T00:05:04 < c4017w> Ultrasauce, are you saying arm-none-eabi-gcc 6.2 is ancient?

2017-11-02T00:07:14 < Ultrasauce> the gcc project perhaps?
2017-11-02T00:07:36 < Steffanx> dekar once provided scripts to build newer gccs not sure if he updated it to 7

2017-11-02T00:12:18 < Ultrasauce> this is where I suggest a linux host and get shit on
2017-11-02T00:15:24 < Ultrasauce> (also don't use exceptions on a microcontroller it sucks)
2017-11-02T00:17:20 < c4017w> I agree. I'm only using them for one function so maybe I should just figure out how to avoid them
2017-11-02T00:17:53 < c4017w> I don't really understand what to do instead of catching an exception though
2017-11-02T00:18:30 < c4017w> Specifically with std::stof
2017-11-02T00:19:18 < Ultrasauce> I'd say don't use std string for the same reason you don't use exceptions
2017-11-02T00:19:55 < c4017w> slowness and hugeness isn't really a problem for this project

2017-11-02T17:14:47 < tpw_rules> does it have real garbage collection
2017-11-02T17:14:58 < Laurenceb> dunno
2017-11-02T17:15:05 < Laurenceb> octave now has "forge"
2017-11-02T17:15:14 < Laurenceb> but its compiled locally, resulting in fail
2017-11-02T17:15:29 < tpw_rules> are binaries too good for them

2017-11-02T17:27:33 < Laurenceb> https://imgur.com/SzILaVZ
2017-11-02T17:27:50 < Laurenceb> guess the datasheet is correct if you average across axes and frequency
2017-11-02T17:28:25 < Laurenceb> looks to me like gyro dsp isnt filtering v well
2017-11-02T17:28:44 < Laurenceb> but as the gyro is actively driven there would be spikes in raw data

2017-11-02T17:31:43 < Laurenceb> the high frequency trend looks kind of similar
2017-11-02T17:32:27 < DelvingDeeper_> Quick question, If I Initialize the DMA to increment the memory address but use the function : HAL_DMA_Start(&hdma_memtomem_dma2_stream2, (uint32_t)&aDST_Buffer1, (uint32_t)&aDST_Buffer2, 1) to do the transfer, It'll never increment the memory right ? How would I go about to get it to increment by 8 bits starting at &aDST_Buffer2.

2017-11-02T17:34:11 < englishman> and is that really noise floor? how have you isolated it
2017-11-02T17:34:23 < Laurenceb> boxes and foam and stuff
2017-11-02T17:34:43 < Laurenceb> could probably do a better job - I still see some spikes in the accel from air con fans
2017-11-02T17:34:56 < englishman> what's the frequency response of foam n stuff
2017-11-02T17:35:05 < Laurenceb> prob in tens of hz
2017-11-02T17:35:28 < englishman> why st gyro?
2017-11-02T17:35:48 < Laurenceb> because the specs are the best
2017-11-02T17:36:01 < englishman> is that millidegrees?

2017-11-02T21:07:21 < upgrdman> lol. "softwareserial" on the retarduino uno can't do 115200 transmit reliably. htf did they fuck it up that bad.
2017-11-02T21:08:55 < upgrdman> planning a new yt video
2017-11-02T21:09:04 < upgrdman> retarduino + esp8266
2017-11-02T21:09:26 < upgrdman> also need a way to test tcp/udp for my telemetry viewer program
2017-11-02T21:09:40 < BrainDamage> just make an arduino expansion board featuring a stm32, then use the stm32
2017-11-02T21:09:49 < BrainDamage> then the arduino toggles an enable pin
2017-11-02T21:09:52 < upgrdman> ^ real pro tip
2017-11-02T21:10:32 < upgrdman> hmm. o, i could use serial for the esp8266 and then use shitsoftwareserial at slow 9600 for debug uart
2017-11-02T21:10:49 < upgrdman> but programming the retarduino will be annoying then, need to unplug esp8266 when flashing
2017-11-02T21:11:51 < upgrdman> less autism, what the FUCK does wireshark allow itself to start as a normal user if it needs admin to actually use any fucking interface.
2017-11-02T21:13:00 < upgrdman> im not on lunix
2017-11-02T21:13:35 < upgrdman> im on windows, because i need to actually get work done instead of just masturbating to the though of richard stallman like you lunix fags do
2017-11-02T21:14:07 < BrainDamage> because wireshark can be used as viewer for the dumps
2017-11-02T21:14:26 < BrainDamage> realtime capture mode even if it's one of main usages, it's not all
2017-11-02T21:14:29 < upgrdman> yes but it should at least have a button or a big fucking warning to run as admin if you want to capture anything
2017-11-02T21:14:53 < upgrdman> instead its like "lolumad. google to find out why i'm showing you zero interfaces."
2017-11-02T21:15:14 < Laurenceb> >not using bascom avr
2017-11-02T21:15:23 < upgrdman> dafuq's dat

2017-11-02T21:15:39 < Laurenceb> better than tarduino
2017-11-02T21:15:49 < englishman> upgrdman, softserial on stm32 would be pretty taxing at 115200 as well
2017-11-02T21:16:46 < upgrdman> englishman, wat. stm32 can easily do 48MHz. that's 416 clocks per bit.
2017-11-02T21:16:58 < upgrdman> even if it blocks to tx, that's very doable.
2017-11-02T21:17:26 < upgrdman> and if interrupt based, the jitter from dick switching should be a small % of 416 clocks
2017-11-02T21:18:34 < englishman> wait are you using an actual avr

2017-11-02T21:19:18 < englishman> should be 16 on xtal
2017-11-02T21:19:18 < Laurenceb> so use bascom
2017-11-02T21:19:24 < Laurenceb> it has soft serial

2017-11-03T02:43:57 < upgrdman> sync, wat
2017-11-03T02:45:09 < sync> well, they are engineered in a way that they experience reluctance torque
2017-11-03T02:45:19 < sync> making them "hybrid"
2017-11-03T02:48:01 < englishman> oh interesting
2017-11-03T02:48:29 < englishman> internal sam reset line does not have enough drive strength to push high both a level shifter and a decoupling cap
2017-11-03T02:48:51 < upgrdman> sync, reluctance is the "desire" to align with a magnetic field, right?
2017-11-03T02:49:18 < sync> reluctance is is magnetic resistance
2017-11-03T02:49:44 < sync> basically a reluctance motor works by making the magnetic path for the q and d components of the field vector unequal
2017-11-03T02:49:50 < sync> thus generating torques

2017-11-03T03:50:30 < upgrdman> i think the only uk "supermarket" i've been to was just a convenience store. sainsburys
2017-11-03T03:50:59 < upgrdman> at least they had very good prices for a conv. store
2017-11-03T03:51:18 < Laurenceb_> they are not the cheapest, but they are decent quality
2017-11-03T03:51:45 < upgrdman> in the usa a conv. store is way overpriced. like 2x a proper supermarket

2017-11-03T04:14:23 < Laurenceb_> nice
2017-11-03T04:14:57 * Laurenceb_ has a technique for stripping out vaguely coherent noise from PSD plots
2017-11-03T04:15:12 < upgrdman> median filter?
2017-11-03T04:15:27 < Laurenceb_> nah - phasor space stuff
2017-11-03T04:15:41 < Laurenceb_> standard interleaved time/frequency bins
2017-11-03T04:16:15 < Laurenceb_> then diff the arg over time in each frequency bit
2017-11-03T04:16:18 < Laurenceb_> *bin
2017-11-03T04:16:35 < Laurenceb_> d=diff(arg(phasors));
2017-11-03T04:16:44 < Laurenceb_> d(find(d<-pi))+=2*pi;
2017-11-03T04:16:57 < Laurenceb_> d(find(d>pi))-=2*pi;mean(d)
2017-11-03T04:18:01 < Laurenceb_> then rotate each bin by angle d and diff with its neighbour, take abs, divide by sqrt(2) then treat as if it were the actual bin value in the plotting code
2017-11-03T04:18:53 < Laurenceb_> seems to completely strip out any coherent noise thats greater than 3dB below the white noise floor
2017-11-03T04:19:38 < Laurenceb_> now I dont have to turn off air con
2017-11-03T04:20:17 < Laurenceb_> basically specgram with a few lines of shit in the middle
2017-11-03T04:20:37 < upgrdman> speculum with shit in the middle
2017-11-03T04:20:42 < Laurenceb_> correct
2017-11-03T04:23:02 < Laurenceb_> ok narrowband 4dB below the noise floor is attenuated by a further 3dB
2017-11-03T04:23:30 < Laurenceb_> once the narrowband approaches the noise floor closer its killed completely
2017-11-03T04:24:02 < Laurenceb_> I'm sure there is some uber analytic proof, but I can just type shit in octave and call it a day
2017-11-03T04:25:31 < Laurenceb_> I suspect this is what piksi does on the fpga
2017-11-03T04:26:25 < Laurenceb_> it has narrowband killing DSP to improve the signal

2017-11-03T20:28:09 < Lux> seems ok
2017-11-03T20:28:13 < Steffanx> Laurenceb: ^ field of expertise
2017-11-03T20:28:48 < Lux> your ds should give you some noise figures to check
2017-11-03T20:29:25 < branjb> is it under some term other than noise? ds ctrl-f noise = 0 results
2017-11-03T20:30:21 < Lux> in the invensense stuff it's named noise in the datasheet
2017-11-03T20:30:29 < Lux> maybe rms ?
2017-11-03T20:31:13 < Lux> for example for the mpu6000 they specify 0.05°/s-rms
2017-11-03T20:31:20 < branjb> ok
2017-11-03T20:31:33 < branjb> so 0.05* of noise is about norm, if it was a mpu6000
2017-11-03T20:32:11 < Lux> yeah
2017-11-03T20:32:37 < Lux> but in my experience with the gyro drift is more important
2017-11-03T20:33:04 < Lux> like temperature drift etc, that can be pretty significant depending on your application
2017-11-03T20:33:07 < branjb> i'm using a complimentary filter atm, seems to be fairly responsive/smooth
2017-11-03T20:33:23 < branjb> no drift just sitting in place
2017-11-03T20:34:02 < branjb> ah, my imu has an entire app note separate from the ds that talks about noise
2017-11-03T20:53:56 < ds2> which IMU?

2017-11-04T02:53:36 < upgrdman> kakimir, https://imgur.com/a/kk2R6
2017-11-04T02:53:56 < upgrdman> im not a beta tester. it was a forced update.
2017-11-04T02:54:31 < kakimir> I have 1703
2017-11-04T02:54:42 < kakimir> better run windows upgrade tool
2017-11-04T02:55:04 < stvn> 1703 for me too
2017-11-04T02:55:15 < stvn> win10proz
2017-11-04T02:55:36 < upgrdman> maybe you god damn foreigners are treated like the lower class of people that you are
2017-11-04T02:55:59 < upgrdman> even dongs got the update a week ago. usa <3 japs
2017-11-04T02:56:00 < branjb> lol
2017-11-04T02:56:19 < stvn> hitachi
2017-11-04T02:56:40 < stvn> australians are too drunk for the windows 10 update
2017-11-04T02:57:33 < kakimir> why the fuck doesn't windows 10 have single build
2017-11-04T02:57:59 < kakimir> but these builds ranging from 4years back to this fall
2017-11-04T02:58:18 < kakimir> it has something to do with all the compatibility issues
2017-11-04T02:58:48 < kakimir> so they don't fuck up some business, industrial whatever environment

2017-11-04T03:00:45 < kakimir> doing it's shit
2017-11-04T03:01:20 < stvn> thanks for one
2017-11-04T03:05:36 < kakimir> upgrdman: so do you have some new computer?
2017-11-04T03:05:49 < kakimir> or do you upgrade builds yourself?
2017-11-04T03:07:35 < upgrdman> well i built this box ~1yr ago.
2017-11-04T03:07:51 < upgrdman> and win10 forces updates, so i dont have much choice.
2017-11-04T03:08:27 < kakimir> it doesn't force builds right away
2017-11-04T03:08:31 < upgrdman> well, i shoulld prolly switch to the "business" branch and hope for better quality
2017-11-04T03:08:41 < kakimir> but like in half year time
2017-11-04T03:08:45 < upgrdman> not for me
2017-11-04T03:08:57 < upgrdman> maybe eurofags get delayed updates
2017-11-04T03:09:08 < kakimir> maybe pro is about forcing build upgrades
2017-11-04T03:09:35 < kakimir> while home edition is like.. they are already mad at you
2017-11-04T03:09:39 < upgrdman> kakimir, what version you have
2017-11-04T03:09:43 < upgrdman> homo edition?
2017-11-04T03:09:56 < kakimir> yes
2017-11-04T03:10:13 < kakimir> is there any benefits for no homo edition?

2017-11-04T03:11:02 < upgrdman> i dunno. when i was a studnet i get a free license for win10pro, and i've kept used it since then
2017-11-04T03:11:16 < upgrdman> free legal license, to be clear.
2017-11-04T03:11:24 < upgrdman> msft dickspark
2017-11-04T03:12:06 < branjb> is there a way to make control loops more responsive without bumping kp super high? low kp = sluggish response, high kp = fast response but way too much overshoot
2017-11-04T03:12:24 < branjb> faster loop time?
2017-11-04T03:12:24 < upgrdman> yes. add the i and d
2017-11-04T03:12:35 < branjb> i and d just make it go crazier
2017-11-04T03:13:07 < upgrdman> not for me :) adding i and d allow you to also raise p without it oscillating so much
2017-11-04T03:13:09 < kakimir> you should use D for that
2017-11-04T03:13:11 < branjb> i should be able to get it to balance with just kp, right?
2017-11-04T03:13:19 < kakimir> no
2017-11-04T03:13:21 < upgrdman> not very well, but kinda
2017-11-04T03:13:23 < branjb> oh
2017-11-04T03:13:40 < branjb> well
2017-11-04T03:13:43 < branjb> interesting
2017-11-04T03:13:56 < kakimir> D is like responsivenes for fast changes
2017-11-04T03:14:13 < kakimir> or actually just change
2017-11-04T03:14:24 < upgrdman> i find it easier to think of D as "predicting the future"
2017-11-04T03:14:33 < upgrdman> and it does a pretty fucking good job of it
2017-11-04T03:14:38 < branjb> is there some kind of rule of thumb for how they should be in proportion to each other? I think I learned that kd shouldn't be higher than kp, but I get better results when kd = 2*kd
2017-11-04T03:14:58 < kakimir> P is just propotional to amplitude of input
2017-11-04T03:15:35 < upgrdman> i just guess-and-checked, starting for 0 and marching the fuck up
2017-11-04T03:15:55 < branjb> starting with p, then i?
2017-11-04T03:15:57 < kakimir> there is guides for PID tuning
2017-11-04T03:16:02 < upgrdman> ya
2017-11-04T03:16:27 < upgrdman> but i only helped a little for me. it's the d that was magical.
2017-11-04T03:16:33 < kakimir> I is like if there is longer error to output it starts to build up to overcome that error
2017-11-04T03:16:47 < branjb> i've also seen weird shit with people doing stepper motor balancers where they have motor_output += pidLoop();
2017-11-04T03:16:50 < kakimir> with I you go easily over the board
2017-11-04T03:16:57 < branjb> is that += just them being weird with ki?
2017-11-04T03:18:35 < kakimir> for I in some applications you may need to implement wind up for I if it builds up really long it takes too much time to come down
2017-11-04T03:18:51 < branjb> that's just something like
2017-11-04T03:18:54 < branjb> if (iTerm_Angle > 200) iTerm_Angle = 200;
2017-11-04T03:18:54 < branjb> if (iTerm_Angle < -200) iTerm_Angle = -200;
2017-11-04T03:18:55 < branjb> right?
2017-11-04T03:20:36 < upgrdman> ya
2017-11-04T03:21:52 < branjb> i also wonder if using 1/32 microstepping is making it worse
2017-11-04T03:22:06 < branjb> because I have gains around ~50,000
2017-11-04T03:22:40 < upgrdman> iirc microstepping that small is bad for torque
2017-11-04T03:23:00 < upgrdman> iirc past 1/2 or 1/4 the only benefit is noise reduction
2017-11-04T03:23:19 < upgrdman> but im not super pro at that stuff
2017-11-04T03:23:33 < branjb> my motors aren't stalling/skipping steps, is there more to torque than that?
2017-11-04T03:23:44 < branjb> heh I was considering just modding servos like you did
2017-11-04T03:23:51 < branjb> but the servos you used were like $80 servos
2017-11-04T03:23:57 < upgrdman> well iirc when microstepping the motors cant really hold those in between positions very well.
2017-11-04T03:24:04 < branjb> hmm
2017-11-04T03:24:10 < branjb> maybe i'll try 1/4 stepping later
2017-11-04T03:24:15 < upgrdman> so if you're trying to stop at a microstep, it might stuggle to maintain that position
2017-11-04T03:24:20 < kakimir> without feedback at least microstepping doesn't really provide any accuracy
2017-11-04T03:24:33 < branjb> the 1/32 stepping is definitely a lot smoother than when i was testing 1/2 or 1/4
2017-11-04T03:24:49 < branjb> and it makes a cooler sound
2017-11-04T03:24:55 < branjb> that's actually the main reason i was using it

2017-11-04T03:27:45 < branjb> I rebuilt my robot though to make it more top heavy
2017-11-04T03:27:45 < branjb> https://imgur.com/a/6VEDe
2017-11-04T03:27:59 < kakimir> branjb: what are you doing?
2017-11-04T03:28:12 < kakimir> stepmotor feedback loop?
2017-11-04T03:28:22 < branjb> trying to make a balancing robot with steppers
2017-11-04T03:29:11 < branjb> only feedback is from IMU
2017-11-04T03:29:29 < branjb> ultimate goal is to do a cascaded pid loop where I can set motor speed, it calculates tilt, and self balances
2017-11-04T03:32:15 < branjb> if a stepper motor is not stalling or skipping steps, is there any difference between a dc motor and encoder where i am controlling speed vs a stepper motor where i am controlling position (thus speed)?
2017-11-04T03:32:35 < upgrdman> https://i.redd.it/ylxu3b1bzsvz.jpg
2017-11-04T03:32:42 < kakimir> branjb: not too much
2017-11-04T03:33:20 < branjb> ok, so switching to a dc motor with encoder doesn't do anything for me that a stepper motor isn't already
2017-11-04T03:33:34 < branjb> that's a very reddit business card
2017-11-04T03:33:48 < stvn> an autistic card
2017-11-04T03:33:50 < kakimir> if you have decent supply voltage for the steppers there is no problems
2017-11-04T03:34:04 < kakimir> but your control architecture sounds like it would have some pitfall in it
2017-11-04T03:34:18 < kakimir> you shouldn't probs offset your motor speed actually
2017-11-04T03:34:27 < kakimir> but let PID completelly control it
2017-11-04T03:34:54 < branjb> I basically copied the algorithm that this guy was using: https://www.youtube.com/watch?time_continue=218&v=nT1FqvNbThU
2017-11-04T03:35:18 < branjb> only difference is his was really small, and mine is larger. struggling to find gains that work though
2017-11-04T03:36:17 < branjb> I think tomorrow I'll start with switching to 1/4 stepping and retuning gains from there
2017-11-04T03:36:27 < kakimir> you should ask upgrdman
2017-11-04T03:36:36 < kakimir> about his architecture
2017-11-04T03:36:38 < branjb> I've asked him a million questions
2017-11-04T03:36:46 < kakimir> look at his codez too
2017-11-04T03:36:48 < branjb> and read his code at least a dozen times
2017-11-04T03:36:49 < branjb> haha
2017-11-04T03:36:57 < kakimir> so it does motor offsetting?
2017-11-04T03:37:04 < upgrdman> https://i.imgur.com/CrSwWDg.gifv

2017-11-04T03:37:36 < kakimir> almost?
2017-11-04T03:38:01 < branjb> well, he's using the interrupt pin on his IMU to trigger his loop, I'm just using a timer
2017-11-04T03:38:17 < kakimir> I would use 2 pidloops
2017-11-04T03:38:39 < kakimir> one that does balancing to desired angle
2017-11-04T03:38:41 < branjb> that's the plan, but before I add the second PID loop I need to make sure the inner (balancing) is tuned, right?
2017-11-04T03:38:59 < kakimir> another one that offsets that angle by inputs and speed
2017-11-04T03:39:06 < branjb> if I can't track and hold an angle does changing that angle really do anything?
2017-11-04T03:39:32 < kakimir> you can not? hmm
2017-11-04T03:39:41 < kakimir> better go simple then
2017-11-04T03:40:04 < branjb> I can get pretty close while supporting the robot, but it can't quite balance on its own
2017-11-04T03:40:12 < branjb> and the "balancing" it does is very violent
2017-11-04T03:40:32 < kakimir> where is your mems?
2017-11-04T03:40:40 < branjb> idk, I have more stuff to experiment with tomorrow
2017-11-04T03:40:41 < kakimir> on top?
2017-11-04T03:40:57 < branjb> if you look at https://imgur.com/a/6VEDe, it's the thing on the bar directly above the motors
2017-11-04T03:41:14 < kakimir> should it be there?
2017-11-04T03:41:19 < kakimir> or higher?
2017-11-04T03:41:23 < branjb> not sure
2017-11-04T03:41:33 < branjb> from what I observed on other bots, they put it close to the motor
2017-11-04T03:41:34 < kakimir> I would say higher
2017-11-04T03:41:48 < branjb> but yeah I would say the angular velocity of the gyro would be more accurate higher up
2017-11-04T03:41:48 < kakimir> what mems you use?
2017-11-04T03:41:55 < branjb> lsm9ds1
2017-11-04T03:42:46 < kakimir> you have 9 degrees of freedom
2017-11-04T03:42:52 < kakimir> lot to play with
2017-11-04T03:42:57 < branjb> haha
2017-11-04T03:43:03 < branjb> only using pitch
2017-11-04T03:43:35 < kakimir> also stepper noise can go thru that frame
2017-11-04T03:43:38 < kakimir> to mems
2017-11-04T03:43:39 < branjb> i've tried using madgwicks and a simple complimentary filter, both give similar pitch data
2017-11-04T03:43:43 < branjb> hmmm
2017-11-04T03:43:45 < kakimir> mems doesn't like noise
2017-11-04T03:44:01 < branjb> i was kind of wondering if that would be an issue
2017-11-04T03:44:06 < kakimir> place it on rubber pads
2017-11-04T03:44:30 < branjb> not a terrible idea
2017-11-04T03:44:35 < branjb> another thing to try tomorrow
2017-11-04T03:45:02 < kakimir> actually add some mass to mems module then suspend it on thin rubber feets
2017-11-04T03:46:47 < kakimir> you should look at mems data for noise or noise jamming

2017-11-04T10:21:37 < jpa-> it has worked for me but took a few tries to find the correct display type for the cheap ebay oleds
2017-11-04T10:21:40 < jsoft> Yeah possibly.
2017-11-04T10:22:00 < jsoft> The previous version of the lib I am using worked with SSD1306.
2017-11-04T10:22:14 < jsoft> I cannot find any model numbers on the display it's self
2017-11-04T10:25:38 < jsoft> jpa-, do you recall if it was i2c, and if you used hw i2c ?
2017-11-04T10:27:33 < jpa-> https://github.com/PetteriAimonen/ebike-controller/blob/master/src/ui_task.c yeah, hw i2c; though it was u8g version 1

2017-11-04T15:53:56 < kakimir> does it really remove all the malware from android phone to just factory reset it? I think I have actually manipulated the rom itself myself too so I'm not buying
2017-11-04T15:54:33 < kakimir> these guides just say, remove suspisious software, clear cache, factory reset
2017-11-04T15:55:38 < kakimir> https://www.addictivetips.com/android/rootcloak-plus-cydia-prevent-apps-from-detecting-root-on-android/ sweet there is root cloak
2017-11-04T15:57:13 < kakimir> once you root the phone to place malware in it.. why not go all the way and compromise rom too?
2017-11-04T15:57:59 < sync> yes, if you are a pro malware you can even rest in the baseband
2017-11-04T15:58:04 < sync> so basically you are fukt anyway
2017-11-04T15:58:32 < kakimir> I would not assume that
2017-11-04T15:58:47 < kakimir> or sure but there is nothing anyone could do
2017-11-04T15:59:00 < kakimir> even all my devices my have been compromised
2017-11-04T15:59:12 < kakimir> that is given how the basebands work
2017-11-04T15:59:35 < kakimir> malicious cell tower even can hack into phone
2017-11-04T16:00:35 < kakimir> there is not so many phone malware pros
2017-11-04T16:01:09 < kakimir> but probs a lot that want to use some plug and play solutions
2017-11-04T16:03:44 < Tectu> the fuck is iphone x? is that iphone 9?

2017-11-04T16:23:04 < Steffanx> > "Doctor"

2017-11-04T16:23:18 < englishman> Dono, sometimes they make you flash back to stock recovery, but this is likely not a problem as I doubt anyone is updating for your phone besides dumb lineageos
2017-11-04T16:23:22 < Steffanx> sounds familiar
2017-11-04T16:23:24 < Laurenceb_> accurate
2017-11-04T16:23:57 < Steffanx> Question is.. do you browse the web much on your phone kakimir
2017-11-04T16:24:06 < Laurenceb_> protip: never talk to ur dentist about important stuff
2017-11-04T16:24:11 < Laurenceb_> or that video is the result

2017-11-04T21:23:57 < kakimir> I'm unemployed for now
2017-11-04T21:24:06 < kakimir> I need to fix all my shit now
2017-11-04T21:24:33 < kakimir> car etc.
2017-11-04T21:24:49 < kakimir> write apply for jubb soon
2017-11-04T21:31:30 < kakimir> it boots but it went to shit
2017-11-04T21:32:38 < kakimir> it's lagging
2017-11-04T21:32:59 < upgrdman> youre in fi right? do they have unemployment handouts or are you on your own
2017-11-04T21:33:04 < upgrdman> "dont freeze. lol."
2017-11-04T21:33:14 < kakimir> handouts
2017-11-04T21:33:26 < upgrdman> nice
2017-11-04T21:35:22 < kakimir> with conditions of course
2017-11-04T21:35:33 < kakimir> I rather get a jubb
2017-11-04T21:35:44 < upgrdman> just curious, what kind of conditions
2017-11-04T21:35:56 < upgrdman> do they drug test you? trump would <3 that.
2017-11-04T21:36:30 < Steffanx> oh, im sorry to hear that kakimir.
2017-11-04T21:36:41 < jpa-> finland has like 117 different social support systems
2017-11-04T21:37:00 < Steffanx> Better get back to back to school and move out of that middle of nowhere place you live now kakimir :P
2017-11-04T21:37:21 < Steffanx> stalked you on google streetview and daaaamn that place was remote
2017-11-04T21:37:30 < upgrdman> lol
2017-11-04T21:39:12 < jpa-> at the very least, one gets enough money for rent and food, with the only condition being that you have no money yourself... which in turn means that those people keep all their money hidden as cash
2017-11-04T21:39:47 < upgrdman> so if youre responsible and save up a big nest egg, you get no help until youre savings are gone?
2017-11-04T21:39:53 < upgrdman> your*
2017-11-04T21:40:13 < jpa-> you get the normal unemployment benefits with their conditions (mostly that you'll have to seek and accept employment)
2017-11-04T21:42:00 < Steffanx> accept employment <= as in .. any employment right?
2017-11-04T21:42:05 < Steffanx> even when totally over qualified
2017-11-04T21:42:08 < branjb> so one of the main incentives for being financially stable in finland is helping people who are not financialy stable?
2017-11-04T21:42:42 < jpa-> Steffanx: kind of yeah, though of course it is pretty easy to make it clear that you don't want the job and most employers will not take you against your will :P
2017-11-04T21:43:40 < jpa-> branjb: nah, more like to gain independence.. the support crap is actually pretty hard to get off of and it's low enough that it limits life choices quite a bi
2017-11-04T21:43:41 < jpa-> t
2017-11-04T21:46:22 < jpa-> unemployment benefits: first 500 days you get 68% of previous salary, or if no previous job, 705 EUR/month; and after 500 days you get 490 EUR/month + rent (they'll have you move to the cheapest place you can find, of course)
2017-11-04T21:46:40 < upgrdman> 500 days WTF
2017-11-04T21:47:52 < Steffanx> i believe its evne 2 years in this country, but partially because i currently pay some insurance stuff for it
2017-11-04T21:48:08 < jpa-> now just recently there is a big outcry among the unemployed population in finland, because they require you to click some button online every now and then to keep the money flowing
2017-11-04T21:49:26 < Steffanx> why an outcry, because they forgot?
2017-11-04T21:49:33 < jpa-> of course
2017-11-04T21:51:22 < jpa-> another fun thing is the rent support, which also applies for students; if you are single, you always get it; but if you are in a relationship, your partner's income affects it - so now they require proof from people that they are not dating their sister that they share appartment with etc.
2017-11-04T21:52:22 < upgrdman> lol
2017-11-04T21:53:21 < Steffanx> is it allowed in finland to date your sister?
2017-11-04T21:54:09 < jpa-> date, sure; fuck, no
2017-11-04T21:55:13 < kakimir> my new phone is just too big
2017-11-04T21:55:22 < kakimir> original moto was the right size
2017-11-04T21:55:26 < jpa-> too many sma connectors?
2017-11-04T21:56:46 < kakimir> when I type I can't hold same time my fingers around the phone
2017-11-04T21:56:48 < kakimir> but flat
2017-11-04T21:57:01 < Steffanx> i wonder if kakimir regrets ever doing those sma connectors
2017-11-04T21:57:07 < kakimir> njet
2017-11-04T21:57:17 < jpa-> "doing"
2017-11-04T21:57:39 < upgrdman> inserting them rectally
2017-11-04T21:57:48 < Steffanx> da da
2017-11-04T22:01:29 < sync> haha wut jpa-
2017-11-04T22:02:17 < upgrdman> lol. just realized that chrome has its own task manager
2017-11-04T22:08:10 < BrainDamage> browsers aren't far off from being an os
2017-11-04T22:08:31 < BrainDamage> they even have their own device drivers for when interfacing with things like smart card and other security tokens
2017-11-04T22:08:40 < BrainDamage> they also have task schedulers, etc
2017-11-04T22:09:13 < BrainDamage> add an io scheduler,video/hid drivers, and a boot manager and you could call it an os

2017-11-04T22:23:17 < ZeroWalker> i am trying to read from SPI1 with DMA and then transfer the data via USB Serial, i try to use a DMA interrupt, but i can't send the data when it's completed, i guess it takes longer than the next time SPI1 uses DMA or something, any ideas?
2017-11-04T22:25:46 < DelvingDeeper_> ZeroWalker: what do you mean by this "i guess it takes longer than the next time SPI1 uses DMA or something"
2017-11-04T22:26:34 < ZeroWalker> well new to this so don't know what's fully going on all the time
2017-11-04T22:26:56 < ZeroWalker> But so i have SPI1 and then have DMA interupt when it has transferred X amount of bytes
2017-11-04T22:27:14 < ZeroWalker> then that interruption calls a function which then sends that buffer via USB Serial
2017-11-04T22:27:53 < ZeroWalker> but i can't send anything "big" at all, i can send like 300 bytes, more and it will cause a freeze and i have to reset the device
2017-11-04T22:28:55 < ZeroWalker> same if i send small stuff and then on the PC halt so it buffers it, that will also cause it to happen. Not really sure how USB Serial works with that, i thought it just sent the data ang didn't have any check if it was received or not, so the receiver just had to be fast enough
2017-11-04T22:29:16 < DelvingDeeper_> Hmmm. I havent used the USB in the device, I've used DMA and SPI so if its a USB problem my knowledge would be limited
2017-11-04T22:30:25 < ZeroWalker> i am just using the USB as i want to send data to the PC, and i think USB uses the same thing as the other serial ports?
2017-11-04T22:32:56 < DelvingDeeper_> ZeroWalker: I'm not sure, as far as I know the USB is pretty complicated to get working? but thats just what I've heard. I'd wait for someone with more knowledge to weigh in
2017-11-04T22:33:00 < ZeroWalker> technically i should have around 1 ms between completion and the next "SCK interval"
2017-11-04T22:33:05 < ZeroWalker> so i am fairly limited
2017-11-04T22:33:17 < ZeroWalker> and there's 3040 bytes to send
2017-11-04T22:34:20 < DelvingDeeper_> I know with my DMA I can transfer large chunks of data, but I'm not using any external interrupts for triggers, I'm using timers to trigger the DMA and I'm not doing any data processing in the main, just using it to trigger the DMA.
2017-11-04T22:36:23 < ZeroWalker> well i am using arduino ide thingy, i got setup and loop, but there's nothing in loop as it's all event based. but can you transfer DMA with the USB Serial?
2017-11-04T22:44:43 < upgrdman> FML. started cleaning that shower fan/light, and the "dust" is so caked on from the years of humidity etc that its like breaking apart a cookie. fuck this, im throwing it in my dish washer for a cycle.
2017-11-04T22:44:50 < DelvingDeeper_> Oh lord I wouldnt use the STM32Duino at all, but thats just my opinion and I doubt anyone here will help with that
2017-11-04T22:45:14 < upgrdman> superbia, thats ok
2017-11-04T22:45:34 < upgrdman> at least then its all be in the filter at the bottom which i can remove and wash off easily
2017-11-04T22:45:45 < upgrdman> or more likely, it
2017-11-04T22:45:59 < upgrdman> or more likely, it'll dissolve in the water/soap slowly and mostly be gone anyway
2017-11-04T22:46:50 < upgrdman> i love washing random shit in my dishwasher. i only fully dissassembled my oven door and washed it in there. came out looking 100% new. <3
2017-11-04T22:46:56 < upgrdman> s/only/once
2017-11-04T22:47:02 < sync> nice
2017-11-04T22:47:13 < ZeroWalker> well i can't really get anything else to work
2017-11-04T22:47:16 < sync> yeah I stick oily machine parts and shit in there
2017-11-04T22:47:33 < ZeroWalker> not really a fan of the arduino stuff tbh, find it very weird most of the time
2017-11-04T22:47:50 < sync> although I never use my dishwasher for actual dishes
2017-11-04T22:48:14 < upgrdman> lol why not
2017-11-04T22:48:44 < ZeroWalker> DelvingDeeper_, what do you use?
2017-11-04T22:49:34 < sync> idk, I just wash the dishes when I'm done cooking/eating
2017-11-04T22:50:09 < DelvingDeeper_> ZeroWalker: I'd go with anything else, either eclipse, keil or atollic
2017-11-04T22:50:42 < ZeroWalker> isn't eclipse just an IDE and not an actual system for uploading the stuff
2017-11-04T22:52:04 < DelvingDeeper> ZeroWalker: you can set it up to do pretty much anything. here's a vid on how to do it: https://www.youtube.com/watch?v=VtjMGCyLEuA
2017-11-04T22:52:05 < upgrdman> ZeroWalker, theres plugins for openocd, jlink, etc.
2017-11-04T22:52:22 < DelvingDeeper> ZeroWalker: it's a two-part
2017-11-04T22:52:25 < ZeroWalker> here's an example of what i like for style of programming: http://paste.awesom.eu/O4VR
2017-11-04T22:52:53 < DelvingDeeper> ZeroWalker: Yeah then you'd defs want to get away from arduino's ide
2017-11-04T22:52:56 < ZeroWalker> well if i can use Visual Studio (which i can with Arduino), then it would be awesome
2017-11-04T22:53:01 < upgrdman> i also like that, but i'd align my comments
2017-11-04T22:53:09 < ZeroWalker> it's jsut a bad copy paste
2017-11-04T22:53:28 < ZeroWalker> and yeah i like when you do stuff more manually, then having a abstract layer that you aren't really sure what it's doing
2017-11-04T22:53:36 < DelvingDeeper> ZeroWalker: Atollic is great if you want something that you can just install and start programming
2017-11-04T22:54:02 < ZeroWalker> but is the system different, i am kinda confused what part is the IDE and what part is the actual Coding
2017-11-04T22:54:15 < ZeroWalker> Arduiono has it's own IDE, but the code is the "setup/loop" right?
2017-11-04T22:55:15 < ZeroWalker> and one problem is, i don't have an ST-Link yet, so i have flashed it via serial to work in USB Bootloader, and it seems only Arduino supports that
2017-11-04T22:56:57 < DelvingDeeper> ZeroWalker: I don't think that should be a problem. Well you've got a few choices now carry on with arduino and see if you can get it working or jump into another ide that has proper support for STM. Time to start doing some google research]

2017-11-04T23:02:15 < DelvingDeeper_> ZeroWalker: Let me know if you get it working though, seems likea cool project. You writing a gui or something for the pc?
2017-11-04T23:02:55 < PaulFertser> ZeroWalker: there's VisualGDB then for you
2017-11-04T23:03:03 < ZeroWalker> will try out Eclipse, though not sure if the USB part will work. super confused as to what is IDE and what is the actual code difference, i thought IDE was only "interface for programming" in a nutshell
2017-11-04T23:03:18 < ZeroWalker> so you can program in Visual Studio for Windows, but also just do it in notepad if you wanted to, but the code is the same
2017-11-04T23:03:28 < ZeroWalker> i am working on a GB LCD Decoder
2017-11-04T23:03:28 < DelvingDeeper_> Pretty much
2017-11-04T23:03:31 < ZeroWalker> and it's Kiiiinda working
2017-11-04T23:03:49 < DelvingDeeper_> I thought you were using the STMduino library?
2017-11-04T23:03:52 < ZeroWalker> but so STM32 has the Setup then Loop thing like the arduino devices:S?
2017-11-04T23:04:04 < ZeroWalker> i am, but i can use it with VCMicro or something
2017-11-04T23:04:14 < ZeroWalker> vMicro
2017-11-04T23:04:14 < PaulFertser> ZeroWalker: only if you're actually using arduino libraries for it
2017-11-04T23:04:47 < ZeroWalker> but what's the original way, shouldn't it technically just be a "main"?
2017-11-04T23:05:00 < DelvingDeeper_> if your using the STM32 libraries, feel free to carry on. If youre using the stm32duino stuff then id switch
2017-11-04T23:05:01 < ZeroWalker> feels like the setup/loop is just a simplified abstraction
2017-11-04T23:06:15 < ZeroWalker> i should be using stm32duino, i think.. well this is was confusing lol, used to there just being like "i program for Windows in C/C++" and that's it, always the same
2017-11-04T23:06:32 < ZeroWalker> and i assume there being the same for linux etc
2017-11-04T23:08:59 < DelvingDeeper_> If your code looks like these github examples your using stm32duino : https://github.com/stm32duino
2017-11-04T23:10:16 < ZeroWalker> well must be using that, as i am tlaking with the developer about help with what iam doing lol xd

2017-11-05T02:06:27 < kakimir> movie recommds?
2017-11-05T02:07:32 < kakimir> my recommd for new movie: Atomic Blonde
2017-11-05T02:09:44 < kakimir> Charlize Theron, really nice 1989 east- west- germany staging and machiavellistic secret agents
2017-11-05T02:11:24 < kakimir> trailer looks like it's all about gunfight, knifefight and fistfight but I think main thing was this mystery, tension thing going on
2017-11-05T02:12:26 < kakimir> why do german polizai use green color?
2017-11-05T02:15:46 < kakimir> *clubhouse green
2017-11-05T02:16:05 < kakimir> maybe it had something to do with nazis

2017-11-05T02:17:49 < kakimir> why your nick is ZeroWalker?
2017-11-05T02:18:34 < ZeroWalker> basically just combined two cool names, Zero and Walker
2017-11-05T02:19:11 < kakimir> you drink zero coke?
2017-11-05T02:19:16 < ZeroWalker> nope
2017-11-05T02:20:57 < kakimir> do you walk?
2017-11-05T02:21:07 < ZeroWalker> sometimes!
2017-11-05T02:21:29 < kakimir> is Walker reffering to star wars?

2017-11-05T02:22:39 < kakimir> yes
2017-11-05T02:28:17 < kakimir> recommend me anime
2017-11-05T02:28:21 < kakimir> I need to fit in
2017-11-05T02:29:59 < ZeroWalker> oh, well haven't watched new ones in ages so can only recommend older, and i mostly watch Romance/Comedy/Harem stuff
2017-11-05T02:32:06 < kakimir> shoot
2017-11-05T02:33:57 < ZeroWalker> DN Angel, Code Geass, Busou Renkin, Darker Than Black, Nyan Koi!, Mayo Chiki!, Zero no Tsukaima, Elfen Lied, Kore wa Zombie desu ka, Death Note, Shakugan no Shana, Spice and Wolf
2017-11-05T02:34:03 < ZeroWalker> there's some;)
2017-11-05T02:34:46 < kakimir> I liek scifi
2017-11-05T02:34:50 < ZeroWalker> hmm scifi
2017-11-05T02:35:16 < ZeroWalker> seen few, i guess Gundam 00
2017-11-05T02:35:22 < ZeroWalker> Majestic Prince

2017-11-05T02:46:09 < ZeroWalker> ah, then i probably don't know many more, not usually into scifi that much, hmm though there is one i enjoyed, Planetes (i think it was called something like that)

2017-11-05T03:21:02 < aandrew> what does btfo stand for? I always read it as "back the fuck off"
2017-11-05T03:22:02 < tpw_rules> it's like bodied the fuck out
2017-11-05T03:22:04 < tpw_rules> idk
2017-11-05T03:22:11 < tpw_rules> it's a thing for racists so i didn't investigate much
2017-11-05T03:24:27 < aandrew> ah it is back the fuck off
2017-11-05T03:24:37 < aandrew> I did the google and it said that
2017-11-05T03:24:47 < tpw_rules> i don't think that's what the racists mean though
2017-11-05T03:24:50 < aandrew> ud says "blown the fuck out"
2017-11-05T03:25:02 < tpw_rules> i think it's that one
2017-11-05T03:25:07 < aandrew> "Acronym which stands for "blown the fuck out." Generally used to refer to a sports team that loses to another by a large margin. Especially if the losing team was expected to win"
2017-11-05T03:28:23 < branjb> i always thought btfo was bent the fuck over

2017-11-05T03:31:16 < branjb> https://photos.app.goo.gl/K9y4Fe9syobdiiFU2
2017-11-05T03:31:44 < branjb> now to figure out how to reduce gyro drift
2017-11-05T03:33:17 < aandrew> hm, are the black hat 2015 presentations not online?
2017-11-05T03:35:52 < aandrew> nvm
2017-11-05T03:36:36 < kakimir> branjb: did you suspend mems?
2017-11-05T03:36:56 < kakimir> did you go to 1/4 step?
2017-11-05T03:37:25 < branjb> yeah
2017-11-05T03:37:27 < branjb> to both
2017-11-05T03:37:32 < branjb> the 1/4 step seemed to help the most
2017-11-05T03:37:52 < aandrew> "suspend mems" ?
2017-11-05T03:37:58 < aandrew> like hang it by its pins or something?
2017-11-05T03:38:43 < branjb> nah
2017-11-05T03:38:52 < branjb> I just put foam tape around where it attaches to the frame
2017-11-05T03:38:54 < branjb> to reduce vibrations
2017-11-05T03:39:29 < branjb> my gyro drifts pretty bad
2017-11-05T03:39:49 < branjb> maybe will try weighting it different in the filter
2017-11-05T03:40:15 < Laurenceb_> what gyro are you using?
2017-11-05T03:40:22 < branjb> mpu6050
2017-11-05T03:40:37 < Laurenceb_> ah
2017-11-05T03:40:38 < branjb> I gave up on the lsm9ds1
2017-11-05T03:40:44 < Laurenceb_> can you plot noise from it?
2017-11-05T03:40:50 < Laurenceb_> whats up with lsm9ds1?
2017-11-05T03:41:07 < branjb> too many settings, I probably configured it wrong
2017-11-05T03:41:11 < Laurenceb_> ah
2017-11-05T03:41:35 < branjb> mainly because the mpu6050 has the built in dsp function
2017-11-05T03:41:46 < branjb> i'm sure if I did a hp filter on the lsm9ds1 it'd be the same
2017-11-05T03:43:25 < Ultrasauce> every gyro drifts, that's what the accelerometer is for
2017-11-05T03:43:33 -!- kOStiX [~kOStiX@fixed-187-188-8-166.totalplay.net] has joined ##stm32
2017-11-05T03:44:24 < branjb> right now just doing angle = angle_gyro * 0.9996f + angle_acc * 0.0004f;
2017-11-05T03:44:26 < Laurenceb_> but ST gyro also spits out weird noise
2017-11-05T03:44:30 < Laurenceb_> at least mine do
2017-11-05T03:44:35 < branjb> if i adjust the weights, i get left drift at the cost of responsiveness right?
2017-11-05T03:44:44 < branjb> less drift*
2017-11-05T03:44:56 < Laurenceb_> woah this is nice
2017-11-05T03:44:56 < Ultrasauce> you need a high pass filter on the gyro
2017-11-05T03:44:57 < Laurenceb_> http://www.st.com/content/ccc/resource/technical/document/design_tip/group0/bf/92/6b/31/e7/c1/4d/c8/DM00311184/files/DM00311184.pdf/jcr:content/translations/en.DM00311184.pdf
2017-11-05T03:46:26 < Laurenceb_> well... it promises much but underdelivers
2017-11-05T03:48:43 < sync> Ultrasauce: lies
2017-11-05T03:49:08 < sync> or rather, there are gyros with very very low drift
2017-11-05T03:49:27 < Laurenceb_> coal spired firestation
2017-11-05T03:52:10 < sync> branjb: you can do some system that looks at the magnitude and uses gyro primarily for high response when the angular rate is high
2017-11-05T03:53:57 < Laurenceb_> http://www.analog.com/en/technical-articles/gyro-mechanical-performance.html
2017-11-05T03:54:20 < Laurenceb_> noise spectrum looks similar to lsm6 if some extra dsp was added
2017-11-05T03:54:33 < Laurenceb_> but there arent any low frequency spurs
2017-11-05T03:58:20 < Ultrasauce> yes ok I reform my suggestion to "ditch the MEMS and spend 6 figures on a ring laser gyroscope" thank sync
2017-11-05T03:58:52 < sync> yes
2017-11-05T03:59:05 < sync> although my fiber gyros were not 6 figures
2017-11-05T03:59:10 < sync> only 0.2°/h tho
2017-11-05T03:59:12 < sync> not that great
2017-11-05T04:02:20 < sync> oh wut, that is a good article Laurenceb_
2017-11-05T04:05:06 < sync> I got a few of those crs43 things
2017-11-05T04:05:10 < sync> they suck pretty hard tbh
2017-11-05T04:11:03 < Laurenceb_> what are you building with fibre gyros?
2017-11-05T04:14:06 < sync> a balance bot over the weekend at the make:r space for luls
2017-11-05T04:14:13 < sync> with only the gyro
2017-11-05T04:16:00 < branjb> use steppers for real fun
2017-11-05T04:16:37 < sync> no, pmsm servo
2017-11-05T04:21:08 < sync> using openloop stuff is something I don't like
2017-11-05T04:22:28 < branjb> anyone used one of those hc06 bt things?
2017-11-05T04:23:23 < branjb> is it as simple as pair with laptop, open com port, put serial on hc06 rx line, it shows up in laptop terminal?
2017-11-05T04:25:22 < Ultrasauce> they dont have UARTs
2017-11-05T04:25:33 < Ultrasauce> it's a simple pulse-length interface
2017-11-05T04:25:48 < Ultrasauce> oh i missed "bt"
2017-11-05T04:26:54 < branjb> or really whatever

2017-11-05T04:27:34 < Ultrasauce> painless and wireless are always mutually exclusive
2017-11-05T04:27:40 < Cracki> there should be bluetooth-serial modules
2017-11-05T04:27:53 < branjb> haha
2017-11-05T04:27:55 < Cracki> I've seen some in those programmable dc stepdown power supplies

2017-11-05T16:18:42 < Steffanx> Boring.
2017-11-05T16:18:56 < englishman> maybe time to close the chat window and go outside?
2017-11-05T16:18:56 < Steffanx> looking into cnc and/or 3d printers a bit
2017-11-05T16:19:05 < Steffanx> lol no its rainy
2017-11-05T16:19:09 < Steffanx> and outside is boring
2017-11-05T16:19:13 < englishman> true
2017-11-05T16:19:22 < englishman> what do you want to do with your 3d cnc printer
2017-11-05T16:19:28 < englishman> add material or subtract material?
2017-11-05T16:19:41 < Steffanx> Yes that's my issue. I could use both :)
2017-11-05T16:19:52 < englishman> then you should get both
2017-11-05T16:20:04 < Steffanx> And im just looking what the cheap arse world has to offer nowadays
2017-11-05T16:20:45 < Steffanx> *into
2017-11-05T16:20:45 < englishman> anything more innovative than cnc3020 and 400w spindle?
2017-11-05T16:21:15 < Steffanx> sure. and cheaper
2017-11-05T16:21:19 < englishman> interesting
2017-11-05T16:21:36 < Steffanx> i think, but as im not an expert it might be crappy as hell
2017-11-05T16:22:15 < Steffanx> https://www.millrightcnc.com/ results dont look to bad but .. meh
2017-11-05T16:22:19 < Steffanx> *too
2017-11-05T16:23:23 < englishman> belt drive....
2017-11-05T16:24:32 < Steffanx> ill belt drive you
2017-11-05T16:27:45 < Steffanx> anyway just orientating mr englishman
2017-11-05T16:29:09 < englishman> yeah
2017-11-05T16:29:19 < englishman> well belts on CNC will really limit you
2017-11-05T16:30:07 < englishman> if you're considering one plz research the difference yourself
2017-11-05T16:31:03 < Steffanx> im probbaly not considering, because huuuge shipping costs
2017-11-05T16:33:04 < Steffanx> and i read somewhere it's tarduino based
2017-11-05T16:33:25 < Steffanx> i dont want to die just yet
2017-11-05T16:36:57 < Steffanx> So how is canada sunday englishman?
2017-11-05T16:43:02 < PaulFertser> Steffanx: (3d printing) I've bought anet a8 from banggood for cheap and it's ~reasonable for the price afaict.
2017-11-05T16:43:59 < PaulFertser> Just wanted some shit to play with.
2017-11-05T16:48:25 < englishman> Steffanx: pitter patter of little kitten feet and rain on the tin roof
2017-11-05T16:50:44 < Steffanx> oh, that thing is so damn cheap that not much can go wrong indeed PaulFertser
2017-11-05T16:51:13 < Steffanx> and you'll just print your own improvements
2017-11-05T16:51:54 < Steffanx> buying
2017-11-05T16:52:14 < PaulFertser> Steffanx: I've added an Ikea glass mirror (and glass cutter to cut it to size)
2017-11-05T16:53:26 < PaulFertser> Steffanx: the connectors in the latest version are ~reasonable, much better than those that were before, so probably not much to worry about.
2017-11-05T16:53:54 < PaulFertser> Steffanx: you'll probably want some additional insulation for the heat bed if you plan to print ABS as it otherwise takes too long to heat up to 110C.
2017-11-05T17:01:26 < Steffanx> PaulFertser, ABS i didnt plan to use that, yet.
2017-11-05T17:02:14 < PaulFertser> Steffanx: ABS parts tolerate higher temperatures and harsher environment (can be used outdoors)
2017-11-05T17:02:47 < PaulFertser> Steffanx: if you're seriously buying a8, I'll be willing to share some important assembly tips which were not obvious for me.

2017-11-05T17:16:11 < Steffanx> ill look into it PaulFertser
2017-11-05T17:16:32 < DelvingDeeper> Hey everyone, got a question on the DMA triggered with timers, pretty sure I could do this, just want to check. I'm triggering the DMA via the timer with a clock, although I want the DMA to rather be triggered by an external signal and then read in a known amount of data (lets call it x) shifted out via the clock signal and then wait until the next trigger?
2017-11-05T17:17:13 -!- emeb [~ericb@ip68-2-65-130.ph.ph.cox.net] has joined ##stm32
2017-11-05T17:28:52 < DelvingDeeper> So for instance the drdy signal triggers the dma, then it reads in 8 bits on the DCLK and then waits for the next DRDY : https://imgur.com/a/SzyeC
2017-11-05T17:32:10 < jpa-> yeah, should work if you set the timer to count on both edges and ARR = 1
2017-11-05T17:41:52 < Steffanx> How is your cnc3020 doing jpa-?

2017-11-05T18:13:20 < PaulFertser> Steffanx: haha, what will you choose then?
2017-11-05T18:13:27 < Steffanx> Results look pretty so-so, but what can you expect from < $200 PaulFertser
2017-11-05T18:13:39 < Steffanx> PaulFertser: dont know yet
2017-11-05T18:14:11 < DelvingDeeper> ZeroWalker: what did you end up using?
2017-11-05T18:14:12 < PaulFertser> Steffanx: results depend a lot on how you assemble and fine-tune it and then on slicing parameters and then on reinforcements you implement.
2017-11-05T18:16:30 < Lux> i honestly wouldn't use abs anymore these days
2017-11-05T18:16:40 < Lux> it's just a pita due to shrinkage
2017-11-05T18:17:09 < Lux> and you can get petg which is as good with temp resistance, just a bit softer
2017-11-05T18:17:59 < ZeroWalker> DelvingDeeper, well, i duno, i am not able to even flash anything and get it working outside of the arduino. I am trying out cubemx
2017-11-05T18:18:22 < PaulFertser> Lux: pita due to bed adhesion or to fit the parts later or why?
2017-11-05T18:18:53 < Lux> if you want accurate parts you have to take it into account and bed adhesion is a probem too
2017-11-05T18:18:56 < Lux> actually warping is
2017-11-05T18:19:04 < Lux> as the part cools down unevenly
2017-11-05T18:19:49 < Lux> iirc abs was like 2% shrinkage vs 0.2-0.5 for pla
2017-11-05T18:20:09 < ZeroWalker> so i use cubemx with VisualGBD and compiled and tried to flash the generated .bin file. i can flash it fine, but it makes the USB device not work, so i have to reset the STM32 and flash a working program
2017-11-05T18:21:41 < branjb> are you flashing it via visual studio or via the st link flash tool?
2017-11-05T18:22:50 < PaulFertser> ZeroWalker: if you are using bootloader, you need to tell cubemx exactly where it expects to find the firmware.
2017-11-05T18:24:24 < PaulFertser> Lux: people usually say that an enclosure helps with uneven cooling.
2017-11-05T18:24:55 < Lux> yeah definetly, but why bother if you can avoid the hassle
2017-11-05T18:24:56 < branjb> Lux: have you tried PEI as a bed? I've had zero issues with warping/cooling since using it
2017-11-05T18:25:08 < Lux> that's what i'm using
2017-11-05T18:25:11 < branjb> ah
2017-11-05T18:25:16 < branjb> I also have an enclosure
2017-11-05T18:25:24 < Lux> pei coated aluminium is amazing
2017-11-05T18:25:30 < branjb> yeah
2017-11-05T18:25:37 < branjb> ABS is actually useful again
2017-11-05T18:25:42 < Lux> it's also super easy to remove the parts
2017-11-05T18:25:44 < Steffanx> Why no A6 PaulFertser ? Seems to be the newer one
2017-11-05T18:26:15 < Lux> the wanhao i3 or rebranded ones are also pretty neat if you don't want to waste time on building that stuff
2017-11-05T18:26:20 < Lux> prints in like 30 mins
2017-11-05T18:28:17 < PaulFertser> Steffanx: a8 was cheaper (plus there was a "sale" ongoing), slightly bigger print area, considerably more tips on reprap wiki and enhancements on thingiverse. And it seemed that a6 had no considerable advantages.
2017-11-05T18:29:40 < PaulFertser> And I do not need it to print, I need it to tinker.
2017-11-05T18:30:48 < Lux> i'd rather do a build from scratch then
2017-11-05T18:31:13 < branjb> I started working on a delta robot build but haven't had time to go back to it
2017-11-05T18:31:16 < PaulFertser> Hehe, I wanted something much less involving.
2017-11-05T18:31:48 < Lux> https://www.thingiverse.com/thing:2254103
2017-11-05T18:33:26 < Lux> maybe as a next step if you like tinkering with that stuff :)
2017-11-05T18:35:47 < PaulFertser> That looks really nice and cool. By tinkering I meant something non-involving, like some people playing "casual games" etc.

2017-11-05T18:41:21 < branjb> the box i'm testing on isn't really flat
2017-11-05T18:47:45 < ZeroWalker> PaulFertser, but i am not flashing with cubemx am i, it's just for generating the starter code?
2017-11-05T18:51:05 < PaulFertser> ZeroWalker: if you're using bootloader then the linker needs to know where (address) the code will end up. To place ISR table etc. And the code is normally not position-independent.

2017-11-05T19:44:36 < PaulFertser> Steffanx: I'll try to share some examples tomorrow when the daylight will be available to make a reasonable photo.
2017-11-05T19:45:18 < PaulFertser> I'd say for diy practical purposes the quality is adequate. And it works out of the box after easy enough assembly.

2017-11-05T19:54:26 < Steffanx> So fixed the connection between the pcb and the bed yet PaulFertser? It seems to set itself on fire?!
2017-11-05T19:56:24 < PaulFertser> Steffanx: newer connectors look pretty adequate (they really differ from those on the "fire" pics). But I still added a mosfet board as I decided to ramp up the voltage to 14V for faster heating and to put less thermal stress on the main board.
2017-11-05T19:57:54 < PaulFertser> Steffanx: I also soldered the power wires directly to the bed with a ~90W iron, can't really tell if it was necessary or not, the connector seems ok, especially if you add some strain relief element to hold the wires (which you need to do either way).
2017-11-05T20:03:46 < Ultrasauce> abs sucks don't print it
2017-11-05T20:04:10 < englishman> hey its all there was, a few years ago
2017-11-05T20:04:25 < englishman> what should i upgrade to
2017-11-05T20:04:54 < englishman> wow MG chem makes petg
2017-11-05T20:04:57 < englishman> and it's cheap
2017-11-05T20:06:44 < Ultrasauce> i use pla
2017-11-05T20:06:50 < Ultrasauce> ive heard good things about PETG yes
2017-11-05T20:07:32 < Steffanx> ABS fumes are nice.
2017-11-05T20:07:50 < Ultrasauce> yeah that's my #1 reason to not recommend it
2017-11-05T20:12:32 < englishman> really? it's my #1 reason to fridge scirros

2017-11-05T20:19:42 < branjb> is there any point to running a control loop faster than your fastest sensor updates?

2017-11-05T23:40:58 < englishman> utter bullshit
2017-11-05T23:41:05 < englishman> and it was like $30
2017-11-05T23:41:19 < englishman> writing angry handwritten letter to company
2017-11-05T23:41:24 < zyp> sounds retarded
2017-11-05T23:41:35 < englishman> totally
2017-11-05T23:41:49 < zyp> only stuff I tend to see that's powered just by being wired in series are dimmers
2017-11-05T23:41:49 < englishman> but nothing i could find had zero minimum load or neutral wire connection
2017-11-05T23:42:19 < englishman> except, this garage motion detector i have , thatwas $3 from china
2017-11-05T23:42:26 < englishman> china > white people once again
2017-11-05T23:42:40 < zyp> heh
2017-11-05T23:43:16 < zyp> or you could go full iot
2017-11-05T23:43:35 < englishman> i thought a $30 lightswitch was already overkill
2017-11-05T23:43:35 < zyp> I recently got a bunch of xiaomi iot shit, including motion sensor
2017-11-05T23:44:00 < englishman> really
2017-11-05T23:44:07 < zyp> not sure what I'll use the motion sensor for, but it was $10 so I figured getting one of those wouldn't hurt
2017-11-05T23:45:08 < englishman> this one is for the basement pantry, so the lights arent on in there even when we are using the basement
2017-11-05T23:45:17 < englishman> unless we are actually in there

2017-11-05T23:46:01 < englishman> do you have a link to a product suite
2017-11-05T23:46:03 < zyp> so far I've just messed around with the temperature sensors
2017-11-05T23:46:15 < zyp> http://home.zyp.no:3000/dashboard/db/sensors?refresh=1m&orgId=1
2017-11-05T23:46:20 < zyp> (if it works)
2017-11-05T23:46:40 < englishman> considering the kidde recall, i might just replace all the smoke detectors etc with china stuff
2017-11-05T23:46:57 < englishman> works yeah
2017-11-05T23:47:48 < englishman> what product is this?
2017-11-05T23:47:52 < zyp> picked up three sensors to test, they seem to work pretty well, so I figure I'll get some more so I can cover all the rooms
2017-11-05T23:48:09 < kakimir> I highly value your opinion englishman
2017-11-05T23:48:21 < zyp> https://xiaomi-mi.com/sockets-and-sensors/xiaomi-mi-temperature-humidity-sensor/ <- these
2017-11-05T23:48:26 < zyp> they are like $10 on aliexpress
2017-11-05T23:48:38 < englishman> nice
2017-11-05T23:48:46 < zyp> also need the gateway
2017-11-05T23:49:01 < zyp> i.e. this: https://xiaomi-mi.com/sockets-and-sensors/xiaomi-mi-gateway-2/

2017-11-05T23:50:15 < zyp> but I'm not buying their relay plugs
2017-11-05T23:50:15 < englishman> oh
2017-11-05T23:50:28 < zyp> I'm just interested in their sensors
2017-11-05T23:50:35 < englishman> mm
2017-11-05T23:50:36 < zyp> I already have a bunch of zwave relays
2017-11-05T23:50:39 < englishman> yeah interesting
2017-11-05T23:50:44 < zyp> and zwave sensors are too fucking expensive

2017-11-06T10:38:28 < DelvingDeeper> If I want the DMA to increment a memory location do I need to provide it with an Array memory location and just set it to increment and it'll do its thing? so in circular mode it'll fill the array and restart once its filled?
2017-11-06T10:39:55 < zyp> yes
2017-11-06T10:40:57 < Fleck> monrning zyp!
2017-11-06T10:41:17 < zyp> hi
2017-11-06T10:41:40 < DelvingDeeper> Got my Minc register set but it just keeps filling the first int in the array, time to debug
2017-11-06T10:41:59 < zyp> DelvingDeeper, have you set the dma job size larger than 1?
2017-11-06T10:42:30 < zyp> job size should be set to the number of entries in your buffer
2017-11-06T10:43:32 < DelvingDeeper> I set it to 1 cause previously when I had it larger it just filled the whole array with the same value. I'll do that, thank you!
2017-11-06T10:44:19 < zyp> what are you transferring from?
2017-11-06T10:45:01 < zyp> if it keeps transferring the same value, it sounds like it's not triggering correctly, make sure you haven't enabled memory to memory mode
2017-11-06T10:46:32 < DelvingDeeper> Doing a timer trigger dma - periph to me
2017-11-06T10:46:36 < DelvingDeeper> mem
2017-11-06T10:48:09 < zyp> is the value you're transferring from supposed to change between timer triggers then?
2017-11-06T10:49:06 < DelvingDeeper> zyp: Yes, but I might have made a mistake. I'll redo the code with the size set to the array size and re-run it. Thanks for the help!

2017-11-06T11:01:12 < qyx> am I allowed to overdrive a 5V tolerant pin if the injected current limit is met?
2017-11-06T11:04:13 < ohsix> how about a simpler question, if it were open drain; i still think you can damage it
2017-11-06T11:05:00 < qyx> but there are esd protection diodes
2017-11-06T11:05:21 < qyx> or tvs or whatever on 5V pins

2017-11-06T11:05:55 < qyx> f042
2017-11-06T11:06:08 < qyx> because I was dumb and forgot to add a n-mosfet
2017-11-06T11:06:11 < ohsix> and electrical spec will show absolute maximum values, don't remember if any were over 5

2017-11-06T11:06:51 < dongs> i sense a disturbance in the wa
2017-11-06T11:09:01 < dongs> what is actually the question. input of 5V into gpio?
2017-11-06T11:09:49 < qyx> no, there is a resistor divider on the input of a switcher
2017-11-06T11:10:01 < qyx> and I need to adjust it by sw
2017-11-06T11:10:23 < qyx> so there is a pwm->lp filter->divider
2017-11-06T11:10:32 < dongs> and its > 5V?
2017-11-06T11:10:38 < qyx> but I didn't realize that it is > 5V
2017-11-06T11:10:52 < dongs> all my experiences of > 5V into STM32 ended with smoke
2017-11-06T11:11:30 < dongs> you should test it htrough like 1-10M resistor maybe
2017-11-06T11:11:31 < aandrew> why would you wan tto put more than that into an STM32
2017-11-06T11:11:52 < ohsix> because of a mistake

2017-11-06T11:12:56 < qyx> if the divider is 1M/1M it sdhould not damage it
2017-11-06T11:14:22 < dongs> i just bought z370 mobo and theres a fucking "RGB LED" connector on it

2017-11-06T14:30:09 < DelvingDeeper> dongs: same here, just tryin to figure out why I can't toggle a pin faster than 14 MHz
2017-11-06T14:30:40 < DelvingDeeper> Opened up the assembly and in the AHBPrescTable: theres a crap load of ; <UNDEFINED> instruction: 0xffffffff
2017-11-06T14:30:53 < dongs> wat
2017-11-06T14:31:04 < dongs> 1) if you want to toggle pins at 14mhz, you use a timer
2017-11-06T14:31:43 < qyx> much mhz
2017-11-06T14:32:24 < dongs> (there's no 2)
2017-11-06T14:35:27 < Thorn> you're unlikely to complain after buying a $6,000 audioph00l cable
2017-11-06T14:35:37 < Thorn> same with dongs and his $6,000 compiler
2017-11-06T14:39:26 < DelvingDeeper> dongs: yeah I literally have just the GPIOC->ODR ^= GPIO_PIN_9; function in a main loop, although my supervisor mentioned that the datasheet says you can hit 108 Mhz, so I must be doing something wrong. Advised me to run it in the main and loop at the assembler. Still stuck on a hard 14 Mhz
2017-11-06T14:40:01 < Thorn> you don't need to reread ODR every time
2017-11-06T14:40:14 < Thorn> which is what that statement does
2017-11-06T14:41:35 < DelvingDeeper> Thorn: definetly true, ill change that
2017-11-06T14:45:31 < DelvingDeeper> Thorn: So it should be possible to hit like 50 Mhz by just toggling the pin on a 216 Mhz processor if everything is set correctly?
2017-11-06T14:46:06 < Ultrasauce> remember that time dongs was like "use a timer"?
2017-11-06T14:46:26 < Ultrasauce> that was pretty cool
2017-11-06T14:46:29 < Ultrasauce> fond memories there
2017-11-06T14:46:37 < Thorn> if it's F4, GPIO is on AHB so it is very fast, 1/2 AHB speed iinm
2017-11-06T14:47:03 < DelvingDeeper> Ultrasauce: Definitely >.< , I understand that.
2017-11-06T14:47:41 < englishman> Thorn: is on the path to being a pro developer
2017-11-06T14:48:28 < DelvingDeeper> Thorn: perfect, its F7, so I think it's also 1/2 AHB. thanks for the help. Just trying to give my supervisor an answer, as the main should be able to give 1/2 AHB (without timers)

2017-11-06T14:49:22 < Thorn> DelvingDeeper: btw, did you set GPIO to VERY_FAST and did you enable the compensation cell or wtf is it called?
2017-11-06T14:51:55 < DelvingDeeper> Thorn: I set it to very fast, went register by register via the ref manual. Compensation cell is completely new to me? I'll read up on it quick

2017-11-06T17:06:37 < dongs> it runs standalone
2017-11-06T17:06:44 < dongs> it has a lcd and joystick and runs wahtever measurement firmware on it
2017-11-06T17:06:45 < zyp> I did

2017-11-06T17:07:17 < dongs> ohw waht teh fuck
2017-11-06T17:07:22 < dongs> yeah i jsut re-read the standalone mode part
2017-11-06T17:07:26 < dongs> it means vs connected to pc by usb
2017-11-06T17:07:27 < dongs> aids.
2017-11-06T17:07:34 < zyp> this board runs standalone, but you stack it on top of the DUT
2017-11-06T17:07:43 < zyp> can stack it on top of the DUT
2017-11-06T17:08:03 < zyp> pages 20-22 have the three ways of using it
2017-11-06T17:08:35 < zyp> the XH-connector being the third way of connecting a DUT
2017-11-06T17:09:41 < zyp> I figure the shit on the bottom is not interesting and might get caught up in other mess on the desk, so it could be snipped off
2017-11-06T17:09:51 < zyp> but the rest doesn't look so bad
2017-11-06T17:10:20 < dongs> but what if you wanna measure power consumption of your retarduino UNO

2017-11-06T21:50:19 < upgrdman> looks more like cheap china tenting
2017-11-06T21:50:36 < upgrdman> poor process control, so they look like ass
2017-11-06T21:51:36 < upgrdman> i had similar but less-extreme tent fuckery when i used dirtypcbs: http://www.farrellf.com/temp/first2layerPcb.jpg
2017-11-06T21:52:42 < karlp> upgrdman: that was what I was more expecting, was just curious ;)
2017-11-06T21:54:57 < upgrdman> when i get ENIG from dirtypcbs the tenting looks a little better, but its still very chinese
2017-11-06T21:55:32 < upgrdman> e.g. only slightly better mask alignment
2017-11-06T21:58:06 < upgrdman> totally off topic: anyone know what the ideal-ish cleaner is to remove skin oils/dirt from painted walls? e.g. that dirty look around light switches, etc.
2017-11-06T21:58:30 < upgrdman> Simple Green "works" but isn't amazeballs.
2017-11-06T22:01:31 < karlp> depends on the paint, but I just use a warm damp cloth.
2017-11-06T22:01:50 < karlp> if it gets beyond that, you're starting to look at time for a paint
2017-11-06T22:02:03 < karlp> or. like, stop smoking inside, that sort of thing :)
2017-11-06T22:02:06 < upgrdman> ya that sounds like more effort than SG
2017-11-06T22:02:50 < upgrdman> i dont smoke :) and its not that extreme. they're all clean now. i was just thinking for later on. sometimes there an amazing solvent for problems where it cuts through it "like a hot knife through butter"

2017-11-06T23:24:36 < jadew> it's about being able to restrain yourself
2017-11-06T23:26:41 < jadew> I think it also has to do with your ability to control the world around you with your words
2017-11-06T23:27:48 < jadew> the better you are at it, the lower the chances that you'll have to resort to violence to get things your way in your life, so you won't have events that would reinforce the idea that violence works
2017-11-06T23:28:45 < jadew> or just going bezerk... you don't even have to be violent to start developing those mental processes
2017-11-06T23:29:29 < jadew> superbia, some guy in texas killed a bunch of people in a church
2017-11-06T23:29:51 < jadew> because he had a quarrel with his mother in law
2017-11-06T23:30:00 < Laurenceb_> >Texas man
2017-11-06T23:30:23 < jadew> aparently that's what stopped him
2017-11-06T23:30:49 < jadew> some random guy started shooting at him (but I don't think he was attending the church)
2017-11-06T23:31:42 < jadew> what flag is that?
2017-11-06T23:32:11 < sync> I think coratia

2017-11-06T23:33:05 < jadew> seems like it, yeah
2017-11-06T23:33:14 < upgrdman> flag looks too complex
2017-11-06T23:33:34 < upgrdman> espically for such a small pissant country ;)
2017-11-06T23:34:03 < munki_> it would be cool if there was like
2017-11-06T23:34:08 < munki_> stm32 simulator online somewhere
2017-11-06T23:34:10 < Laurenceb_> Hurry! I hear that Elon Musk is in need of an Arduino sketch from a self balancing robot to help with his Space-X thingÂ’s landing.
2017-11-06T23:34:16 < munki_> is anyone aware of this
2017-11-06T23:34:38 < jadew> lol Laurenceb
2017-11-06T23:34:53 < upgrdman> munki_, prolly not. anything past blinking an LED would be non-trivial
2017-11-06T23:35:07 < upgrdman> it would likely require RE'ing the silicon
2017-11-06T23:35:21 < munki_> yeah
2017-11-06T23:35:22 < munki_> shame
2017-11-06T23:35:26 < upgrdman> to IP theft of the HDL
2017-11-06T23:35:39 < munki_> there's like cloud fpga right
2017-11-06T23:36:05 < upgrdman> well from a functionality perspective, fpgas can be very simple
2017-11-06T23:36:19 < upgrdman> at least the "classic" fpga, not the new RFSoC etc
2017-11-06T23:38:24 < munki_> yea
2017-11-06T23:38:27 < munki_> i just wish there was like
2017-11-06T23:38:48 < munki_> some sort of way i could do some embedded dev work without having my device with me all the time
2017-11-06T23:39:10 < upgrdman> dev board + web cam? ;)
2017-11-06T23:39:11 < munki_> and some more advanced planning
2017-11-06T23:39:22 < munki_> haha
2017-11-06T23:39:34 < munki_> it would be cool to do more advanced board design virtually tho
2017-11-06T23:39:49 < upgrdman> gdb works over the network, can flash and debug from across the globe :)
2017-11-06T23:40:01 < munki_> yeah true
2017-11-06T23:40:13 < munki_> but you have to have all your peripherals connected already for that to make sense
2017-11-06T23:41:16 * upgrdman imagines an stm32disco, a breadboard, and a bunch of breakout boards. then a MASSIVE automated crossbar switch from the old telephone eta.
2017-11-06T23:41:25 < munki_> hahaha
2017-11-06T23:41:31 < munki_> that would be so lit
2017-11-06T23:41:34 < upgrdman> would be kinda fun to see
2017-11-06T23:41:38 < munki_> cloud scale prototyping
2017-11-06T23:41:39 < upgrdman> but also super autistic
2017-11-06T23:41:49 < munki_> have like each pin from each breakoutboard
2017-11-06T23:41:56 < munki_> matrix'd out to each possible pin from the disco
2017-11-06T23:42:08 < munki_> could be a good use for an fpga i guess right
2017-11-06T23:43:12 < munki_> have every pin from the disco and every pin from the breakout boards connected to different pins on the fpga and just define which ones are connected in hdl
2017-11-06T23:55:16 < Laurenceb_> inventions for your autistic manchild
2017-11-06T23:55:25 < Laurenceb_> sounds ##stm32 worthy

2017-11-07T00:28:58 < capacitor> good morning Steffanx
2017-11-07T00:33:00 < sync> of course kakimir
2017-11-07T00:33:45 < kakimir> what do you think about DC4 silicone?
2017-11-07T00:35:12 < sync> for what?
2017-11-07T00:35:42 < kakimir> for connectors
2017-11-07T00:36:26 < sync> silicone is not great as I explained before
2017-11-07T00:36:35 < sync> it is ok if you only need to fill them once tho
2017-11-07T00:36:36 < kakimir> all way from root of the wire to connector leads to connector seal
2017-11-07T00:36:41 < kakimir> once?
2017-11-07T00:36:51 < sync> yes, fill them once and never disconnect
2017-11-07T00:36:55 < kakimir> why?
2017-11-07T00:37:37 < sync> I guess it'd be fine if you only disconnect the plugs without load
2017-11-07T00:37:49 < sync> but otherwise you will end up with sio2 on your connector
2017-11-07T00:37:50 < kakimir> yes
2017-11-07T00:38:23 < kakimir> I mean dc4 is used in vehicle use isn't it?
2017-11-07T00:38:39 < kakimir> in wiring harness connectors
2017-11-07T00:38:57 < upgrdman> sio2 == glass, right?
2017-11-07T00:39:05 < BrainDamage> yes, or quarz
2017-11-07T00:39:18 < kakimir> you are not connecting or disconnecting those while on load
2017-11-07T00:39:27 < sync> yes, then it is fine to displace water
2017-11-07T00:39:45 < sync> but say on relay contacts or mains switches, you should not use it
2017-11-07T00:39:51 < sync> that is where pulmotin comes in

2017-11-07T02:06:03 < dfgg> counldn't it be sth like H7 or H4? ,_,
2017-11-07T02:06:18 < kakimir> jadew: isn't that first tablet like out-dated tech already?
2017-11-07T02:06:42 < kakimir> not like - a bit outdated
2017-11-07T02:07:11 < jadew> kakimir, sure, but I don't use it to play games
2017-11-07T02:07:42 < upgrdman> lol. target black friday ad shows the kindle table for $30. i wonder what the all cost to manuf it is
2017-11-07T02:07:48 < upgrdman> tablet*
2017-11-07T02:07:58 < jadew> ok, I want that
2017-11-07T02:08:22 < kakimir> you can't get tablet like that anymore
2017-11-07T02:08:30 < upgrdman> i mean fuck, if nothing else, it'd be neat to repurpose the tablet's lcd for $30
2017-11-07T02:08:35 < kakimir> but for industry use or so maybe
2017-11-07T02:08:42 < kakimir> with price tag accordingly
2017-11-07T02:08:50 < jadew> kakimir, what tablet?
2017-11-07T02:09:19 < kakimir> tablet that has all the function of first lenovo tablet
2017-11-07T02:09:31 < kakimir> connectors, real buttons and shit
2017-11-07T02:09:32 < jadew> ah, yeah
2017-11-07T02:09:41 < jadew> it's really nice in this regard
2017-11-07T02:10:21 < upgrdman> didnt some faggot in here like the Chewy brand of tablets
2017-11-07T02:10:39 < kakimir> connectorless is ideal but only when it's not to promote corporation hegemony
2017-11-07T02:11:07 < kakimir> it's future
2017-11-07T02:11:15 < jadew> upgrdman, looks like a nice tablet
2017-11-07T02:11:26 < upgrdman> ya looks nice, but cpu is weak as fuck
2017-11-07T02:11:37 < upgrdman> i guess it would be good for web browsing
2017-11-07T02:11:44 < upgrdman> and irc
2017-11-07T02:12:04 < kakimir> that was the time when I wished my phone would have more performance
2017-11-07T02:12:08 < upgrdman> i guess my demands are too high for the table form factor
2017-11-07T02:12:19 < jadew> I just want to read on mine
2017-11-07T02:12:33 < upgrdman> jadew, pdfs or web or what
2017-11-07T02:12:37 < kakimir> then came excess flash era and excess ram era
2017-11-07T02:12:38 < jadew> pdfs
2017-11-07T02:12:46 < upgrdman> iirc the eink kindles can do pdfs
2017-11-07T02:12:56 < jadew> I guess my perfect tablet would be slim, e-ink but with a slightly better refresh rate
2017-11-07T02:12:57 < upgrdman> i just wish they make a new kindle dx-sized one
2017-11-07T02:13:17 < jadew> I never used a kindle, but I saw one and it was a bit too small for my liking
2017-11-07T02:13:19 < kakimir> dx?
2017-11-07T02:13:35 < upgrdman> kakimir, ~10inch eink kindle
2017-11-07T02:13:38 < kakimir> is there A4 size e-paper readers?
2017-11-07T02:13:56 < jadew> kakimir, that would be impressive
2017-11-07T02:13:59 < upgrdman> there this, which looks nice but the web site reaks of dickstater marketing https://remarkable.com/
2017-11-07T02:14:12 < upgrdman> i think they actually were a dickstarter or indiegofuckyourself
2017-11-07T02:14:36 < jadew> that looks nice
2017-11-07T02:14:39 < upgrdman> and sony has some half-assed jap 10 inch eink tablet
2017-11-07T02:14:44 < jadew> but do they have product?
2017-11-07T02:14:53 < upgrdman> that they arent even brave enough to sell outside of japanistan
2017-11-07T02:14:59 < upgrdman> fuck if i know
2017-11-07T02:15:14 < upgrdman> they claim to have sold many, but again, their whole web site looks scammy as fuck
2017-11-07T02:15:37 < kakimir> shit it's expensive
2017-11-07T02:15:52 < upgrdman> ya big eink always it. its very niche
2017-11-07T02:16:38 < upgrdman> so jadew will have to buy some used kindle on ebay since hes too poor
2017-11-07T02:16:41 < jadew> https://www.cnet.com/products/remarkable-tablet/preview/
2017-11-07T02:16:48 < jadew> you're probably right
2017-11-07T02:17:24 < upgrdman> oh damn, that photos make it look like total shit. contrast ratio of maybe 5, lol
2017-11-07T02:17:42 < kakimir> ipads saturate markets
2017-11-07T02:17:44 < jadew> what's the biggest kindle?
2017-11-07T02:18:00 < upgrdman> that's one thing the newer kindles do very nicely. their eink when white actually looks very close to white paper
2017-11-07T02:18:10 < kakimir> how often do you need to recharge epaper reader?
2017-11-07T02:18:10 < upgrdman> jadew, kindle dx but its discontinued
2017-11-07T02:18:19 < upgrdman> the new 7" kidnle is the biggest iirc
2017-11-07T02:18:37 < upgrdman> kakimir, supposedly monthly or even less
2017-11-07T02:18:39 < jadew> oh, that looks good
2017-11-07T02:18:44 < jadew> the dx one
2017-11-07T02:19:38 < capacitor> dx4lifebro
2017-11-07T02:19:46 < upgrdman> dx == dicks
2017-11-07T02:19:47 < kakimir> does it have pen?
2017-11-07T02:19:52 < upgrdman> no
2017-11-07T02:20:37 < capacitor> http://www.dx.com/p/p6400-10x-500mhz-oscilloscope-scope-clip-probe-130cm-cable-369079#.WgD8RNCWaUk
2017-11-07T02:20:39 < capacitor> is this good?
2017-11-07T02:20:59 < upgrdman> buying test equipment from dx.com ... always a good idea
2017-11-07T02:21:12 < jadew> heh
2017-11-07T02:21:29 < upgrdman> im sure the chinese have mastered how to make a 500MHz passive probe. utterly mastered.
2017-11-07T02:21:50 < jadew> I have the 150 MHz ones, I used the ground clip
2017-11-07T02:22:00 < jadew> made a longer ground clip
2017-11-07T02:22:06 < kakimir> Sony DPT-RP1
2017-11-07T02:22:10 < kakimir> check it out
2017-11-07T02:22:16 < upgrdman> i try to use the ground SPRING for anything >30MHz
2017-11-07T02:22:29 < kakimir> 13.3"
2017-11-07T02:22:46 < kakimir> https://www.sony.com/electronics/digital-paper-notepads/dpt-rp1
2017-11-07T02:22:48 < upgrdman> ya thats the sony shit i mentioned
2017-11-07T02:23:04 < jadew> ok, that looks great
2017-11-07T02:23:18 < jadew> I could actually read books on that
2017-11-07T02:23:25 < upgrdman> or actually that might be a new version
2017-11-07T02:23:35 < upgrdman> i recall a bulky-er one
2017-11-07T02:23:44 < kakimir> https://www.youtube.com/watch?v=EQO3-gQ3CmA
2017-11-07T02:24:07 < kakimir> jadew: *CONSUME*
2017-11-07T02:24:11 < jadew> 600 eur tho
2017-11-07T02:24:27 < kakimir> but that has that jap vibe
2017-11-07T02:24:34 < kakimir> they want that shit
2017-11-07T02:24:41 < capacitor> figured the 500mhz chinese one would be good for 20mhz right?
2017-11-07T02:25:04 < jadew> the 150 MHz one is good to 100 MHz for sure
2017-11-07T02:26:17 < capacitor> hmmm
2017-11-07T02:26:27 < capacitor> i just got the original riglols
2017-11-07T02:26:44 < jadew> did you break them?

2017-11-07T03:23:25 < Laurenceb_> >letting ur kids watch youtube at random
2017-11-07T03:23:51 < jadew> there are fake cartoons (look like the ones they normally watch) and they seem harmless at first but then they descend into weird violence and super bad behaviour
2017-11-07T03:24:17 < jadew> it's not random, their entire feed would be filled with normal cartoons and then this shit gets injected in there
2017-11-07T03:24:55 < jadew> it took us by surprise at first, but now we're paying constant attention to that

2017-11-07T11:10:09 < dongs> so what i said?
2017-11-07T11:10:28 < karlp> qyx: is that my i2c-master test code? or the lib code after I was working on it?
2017-11-07T11:12:30 < qyx> karlp: it is the lib code
2017-11-07T11:12:36 < qyx> I added some sort of timeout

2017-11-07T11:15:57 < dongs> since its from lunix
2017-11-07T11:16:10 < qyx> you should -pedantic or whatever
2017-11-07T11:16:17 < dongs> i am not gonna use gcc, lol
2017-11-07T11:16:17 < qyx> I don't remember exactly
2017-11-07T11:16:31 < dongs> if anything I'm gonna be looking for a vstudio flag to disable this shit

2017-11-07T11:19:23 < dongs> i mean besides opensource masturbation
2017-11-07T11:19:42 < dongs> what situation would one have a use for signed size datatype
2017-11-07T11:23:30 < dongs> wow this tool used "restrict" isntead of __restrict
2017-11-07T11:26:11 < zyp> _______restrict
2017-11-07T11:26:29 < dongs> why opensource code always so shit?
2017-11-07T11:33:24 < zyp> better switch to C++, C++ allows empty initializer lists
2017-11-07T11:35:20 < karlp> dongs: shoulda used gdb to save a region of memory to file ;)
2017-11-07T11:36:02 < dongs> karlp: right
2017-11-07T11:36:13 < dongs> zyp, is that why it worked?
2017-11-07T11:36:23 < zyp> why what worked?
2017-11-07T11:36:30 < dongs> gcc compiled it
2017-11-07T11:36:33 < dongs> inside a .c file
2017-11-07T11:36:52 < zyp> what C++ allows doesn't matter when you're compiling in C mode

2017-11-07T11:41:08 < zyp> that's the right way of solving it
2017-11-07T11:41:18 * karlp can never remember which one is c and which one is c++ for explicit array null but remembers they are dumb an incompatible
2017-11-07T11:41:37 < zyp> incompatible how?

2017-11-07T11:44:05 < zyp> foo.cpp:3:24: error: initializer for aggregate with no elements requires explicit braces
2017-11-07T11:44:08 < zyp> struct foo_t foo[3] = {0};
2017-11-07T11:44:39 < zyp> hmm, no, scratch that
2017-11-07T11:44:44 < karlp> http://en.cppreference.com/w/c/language/array_initialization notes section
2017-11-07T11:44:52 < zyp> my struct was empty, once I added some variables it compiles without errors
2017-11-07T11:45:05 < karlp> it claims that {0} should work in both c and c++
2017-11-07T11:45:11 < zyp> it does
2017-11-07T11:45:20 < karlp> but I think I ran into gcc or clang or something giving out warnings on it when it shouldn't have been
2017-11-07T11:45:32 < karlp> and it might have only been since c11 or something that it was formally put in.
2017-11-07T11:45:42 * karlp shrugs I just remember there being pain and frustration
2017-11-07T11:46:59 < zyp> well, it raises shit if the struct is empty
2017-11-07T11:47:11 < zyp> "aggregate with no elements"
2017-11-07T11:48:54 < zyp> which in C is illegal in itself
2017-11-07T11:48:59 < zyp> foo.c:1:1: warning: empty struct is a GNU extension [-Wgnu-empty-struct]
2017-11-07T11:49:00 < zyp> struct foo_t {};
2017-11-07T11:52:05 < dongs> i always use { 0, }
2017-11-07T11:52:15 < dongs> apparently , causes it to initialize or whatever
2017-11-07T11:52:33 < dongs> even if it doesnt, i just leave it there.
2017-11-07T11:52:41 < karlp> ah, I think it was when the first element of the struct was another struct,
2017-11-07T11:52:51 < dongs> i didnt write this shitty opensores stuff, im just making it build on windows
2017-11-07T11:57:06 < karlp> ok, might have been when I was trying out -pedantic? *shrugs*
2017-11-07T11:57:20 < karlp> {} causes warnings only in pedantic for c89/99/11 here.
2017-11-07T11:58:13 < karlp> ah, but older compiler does.
2017-11-07T11:58:27 < karlp> my old arm-none 4.7 gies all sorts of warnings on that
2017-11-07T11:59:42 < karlp> and 4.8, 4.9. 5.2 is fixed at least.
2017-11-07T12:00:12 < karlp> zyp: that's getting warnings from the {0} format, that was _meant_ to have been working.
2017-11-07T12:00:37 < karlp> and in those versions, the {} would _not_ give warnings.
2017-11-07T12:01:26 < karlp> so, tl;dr: use {0}, if you get warnings, update your compiler.
2017-11-07T12:11:55 < jadew> dongs, was sleeping, but I didn't know if you can anyway
2017-11-07T12:12:52 < dongs> you cant
2017-11-07T12:13:02 < dongs> not wihtout some bullshit extension written b some romanian hacker
2017-11-07T12:13:04 < jadew> if it was text, you could create a watch for that memory location and open it with the little magnifying glass icon
2017-11-07T12:13:08 < dongs> from that stacksexchange link
2017-11-07T12:13:14 < jadew> then you could copy it with ctrl + c
2017-11-07T12:13:25 < dongs> jadew: i did better, i selected teh hex part only (with alt-clic kor ctrlclick i forgot)

2017-11-07T12:32:22 < zyp> nice
2017-11-07T12:33:13 < zyp> are there currently other mcus with the main ram nonvolatile, apart from the fram msp430?
2017-11-07T12:38:14 < karlp> not that I'm aware of, but my friend int his has been saying there's more and more stuff that looks like it iwll be coming online,
2017-11-07T12:38:39 < karlp> some of the "shit's hard mixing normal cmos and this in the same project" has been getting easier and better tooling.
2017-11-07T12:38:43 < karlp> just think it's neat.
2017-11-07T12:42:57 < zyp> yeah
2017-11-07T12:43:01 < dongs> does anyone actualyl use MSP420 shit
2017-11-07T12:43:04 < dongs> such a garbage proc
2017-11-07T12:43:21 < zyp> I got the fram launchpad, but I never tried it
2017-11-07T12:44:17 < dongs> i got the free launchpad and kept it in a drawer for a year then sold on yahoo auctions to some dumb jap
2017-11-07T12:44:21 < dongs> i think i made $10 on it
2017-11-07T12:44:22 < zyp> keeping the entire system state in nvram seems convenient for low power stuff
2017-11-07T12:45:06 < zyp> just turn off everything and go to sleep, then wake up again whenever and keep going without reinitializing anything
2017-11-07T12:46:06 < karlp> I'd _love_ proper nvram.
2017-11-07T12:46:25 < zyp> especially for stuff that does energy harvesting, like nfc cards and whatever
2017-11-07T12:46:34 < karlp> even just so as not to have to fuck around with erasing and writing and sections and shit in flash, or detecting power fail properly and reliabily
2017-11-07T12:46:42 < karlp> just keep it in ram, no more work to do.
2017-11-07T12:47:23 < zyp> well, as a flash replacement it becomes a question of whether the price makes it worth it
2017-11-07T12:49:13 < zyp> heh, apparently there was an earthquake in norway this morning
2017-11-07T12:50:36 < zyp> news is full of people talking about how it's the "strongest in norway in ten years" and how scary it was
2017-11-07T12:50:44 < zyp> apparently it was magnitude 3.8
2017-11-07T12:59:48 < karlp> I'd be fine with just a small region of nvram, that just worked better than eeprom
2017-11-07T12:59:59 < karlp> I want unlimited writes and low write latency
2017-11-07T13:00:49 < zyp> fair

2017-11-07T13:20:28 < dongs> if i save it into txt and load into chrome its jap
2017-11-07T13:20:42 < dongs> but since they removed the encoding menu like 2 years ago
2017-11-07T13:20:50 < dongs> you can no longer force/tell what the encoding autodetected to
2017-11-07T13:21:09 < dongs> oh wtf im stoned its just utf8

2017-11-07T13:27:10 < dongs> this is related
2017-11-07T13:27:20 < dongs> basicalyl the chars are inside that group of stuff
2017-11-07T13:27:30 < dongs> and theres control/shift characters to swap whatever plane in/out
2017-11-07T13:27:39 < dongs> so the meaning of bytes changes to wahtever plane is shifted in etc
2017-11-07T13:27:47 < zyp> right
2017-11-07T13:27:49 < dongs> there's locking shifts, non-locking shifts, all sorts of crazy shit

2017-11-07T13:56:56 < jadew> lol, really?
2017-11-07T13:57:45 < jadew> I never considered it before, but it could solve the counterfeit hw issue
2017-11-07T13:57:48 < zyp> "hey, you guys sent me this shit, pls let me sign the NDA so you can tell me how to use it"
2017-11-07T13:58:20 < dongs> jadew, nobody is gonna wanna use your shitty text editor if ti needs a parallel port dongle to work
2017-11-07T13:59:00 < jadew> dongs, no, I don't mean it as a security dongle, but embedded in a an actual hw product
2017-11-07T13:59:36 < jadew> altough, I don't see why you couldn't make your own thing
2017-11-07T13:59:44 < emeryth> jadew: this has been solved for years by using sim/smartcards
2017-11-07T14:00:10 < dongs> good fucking luck getting datasheet on a smartcard
2017-11-07T14:00:19 < dongs> or buying them from non-dodgy vendors
2017-11-07T14:00:31 < dongs> last time i worked with smartcard shit
2017-11-07T14:00:34 < zyp> haha
2017-11-07T14:00:34 < dongs> they shipped all the docs
2017-11-07T14:00:37 < dongs> on PAPER
2017-11-07T14:00:42 < dongs> with fucking company name plastered all over it
2017-11-07T14:00:48 < dongs> like 10kg of paper manuals
2017-11-07T14:01:22 < zyp> I tried inquiring about ST31, they weren't very interested in talking to me unless I wanted an annual volume of 100k
2017-11-07T14:02:55 < jadew> why do they do that?
2017-11-07T14:03:16 < dongs> to thwart tv pirates

2017-11-07T14:03:33 < zyp> probably because there's not much point in an NDA if anybody can sign it
2017-11-07T14:03:48 < jadew> zyp, I mean why have a NDA at all
2017-11-07T14:03:51 < zyp> shame though, ST31 seems neat

2017-11-07T14:05:24 < dongs> also that
2017-11-07T14:05:44 < zyp> ST31 have some flash-based parts, but they have the same volume requirements for those

2017-11-07T14:14:28 < zyp> I'm building an ethernet bootloader for this workstuff, wondering what protocol to use for it
2017-11-07T14:14:39 < dongs> tftp?
2017-11-07T14:14:41 < dongs> obviously
2017-11-07T14:15:12 < zyp> if I should just make some custom shit right on top of ethernet, write some super simple IP/UDP shit or throw in entire lwip
2017-11-07T14:15:36 < dongs> just blindly accept firmware updates on broadcast udp
2017-11-07T14:15:48 < zyp> lwip seems super overkill since it won't be used for anything else
2017-11-07T14:15:48 < dongs> verify nothing
2017-11-07T14:16:57 < zyp> just IP and UDP without fragmentation is mostly just a matter of adding/removing headers, plus handling ARP
2017-11-07T14:17:53 < dongs> im sure keil has a IP library thats less bloated than lwip

2017-11-07T14:28:38 < dongs> k i got this jap EPG shit figured out
2017-11-07T14:29:16 < zyp> I mean, that's what I did for arcin

2017-11-07T14:30:17 < zyp> C or C++, built with MSVC
2017-11-07T14:30:19 < karlp> there's also uip, which is from the same people, written many years later, and designed to be smaller...
2017-11-07T14:30:19 < dongs> o
2017-11-07T14:30:30 < karlp> and then picotcp too.
2017-11-07T14:30:37 < karlp> though I think picotcp is gplaids
2017-11-07T14:30:37 < dongs> wat about kontiki

2017-11-07T14:32:47 < zyp> might be, but IP/UDP alone seems thin enough that it might not be worth maintaining a third party integration vs just writing a simple implementation

2017-11-07T14:34:28 < zyp> if I only care about packets small enough to not need fragmentation, it's just a matter of adding/handling headers

2017-11-07T14:35:56 < BrainDamage> ipv4 or ipv6?
2017-11-07T14:36:03 < karlp> haven't actually looked at this in years
2017-11-07T14:36:10 < BrainDamage> because ipv6 has no broadcast, only multicast ranges

2017-11-07T14:51:19 < zyp> Laurenceb_, your snr is too low today
2017-11-07T14:52:28 < jadew> so what is Zout? http://5.12.75.151/stuff/zout.png
2017-11-07T14:53:04 < jadew> I came up with 86.439, but apprently it's wrong
2017-11-07T14:54:54 < Laurenceb_> jadew: what is that supposed to do?
2017-11-07T14:55:14 < jadew> Laurenceb_, it's just an emitter follower
2017-11-07T14:55:18 < jadew> biased
2017-11-07T14:55:27 < zyp> jadew, so what's correct?
2017-11-07T14:55:36 < jadew> zyp, apparently 110
2017-11-07T14:55:48 < jadew> but I'm inclined to think that's wrong
2017-11-07T14:55:59 < zyp> that doesn't make sense
2017-11-07T14:56:01 < jadew> without accounting for re, it would be 86
2017-11-07T14:56:27 < jadew> but re shouldn't have that big of an effect, since it should be in series with R3, no?
2017-11-07T14:56:42 < zyp> wikipedia says R_source / B, which even at 10k/100 would be 100, and any other shit should bring it down, not up
2017-11-07T14:56:45 < jadew> so what's the difference between 7.5k and 7.526k
2017-11-07T14:57:02 < zyp> so your figure of 86 sounds reasonable to me
2017-11-07T14:57:26 < jadew> zyp, well, it's ((10k || R1 || R2) / 100) || RE
2017-11-07T14:57:42 < zyp> exactly
2017-11-07T14:57:47 < jadew> but there's also the intrinsec emitter resistance, which is 25-26
2017-11-07T14:57:56 < jadew> but that should add to RE, not to the result, no?
2017-11-07T14:58:27 < zyp> why?
2017-11-07T14:58:39 < jadew> because it would be in series with R3
2017-11-07T14:58:57 < jadew> so RE would be R3 + re
2017-11-07T14:59:05 < zyp> yes, but it'd also be in series with R_load
2017-11-07T14:59:26 < jadew> yeah, R load is assumed to be high
2017-11-07T15:00:08 < zyp> sure, but for the purpose of the calculation, isn't Z_out == R_load
2017-11-07T15:00:34 < jadew> no, the load could vary
2017-11-07T15:00:45 < jadew> but Zout is what you see when you look through the output port
2017-11-07T15:00:52 < jadew> *into
2017-11-07T15:01:23 < BrainDamage> ((( ( Zin || R1 || R2 ) + beta/gm ) / 100) +re) || R3
2017-11-07T15:01:53 < BrainDamage> the base-emitter junction has an intrinsic resistive behaviour
2017-11-07T15:01:57 < jadew> hold on a sec, why do you add re there?
2017-11-07T15:02:13 < jadew> why don't you do || (R3 + re)?
2017-11-07T15:02:35 < zyp> because from the perspective of the output, it's in series with the entire input network
2017-11-07T15:02:39 < jadew> you're right
2017-11-07T15:02:41 < jadew> yeah
2017-11-07T15:03:22 < zyp> (this is one of the reasons I don't do analog shit)
2017-11-07T15:04:04 < jadew> BrainDamage, thanks
2017-11-07T15:04:15 < BrainDamage> don't forget the beta/gm term btw
2017-11-07T15:04:32 < BrainDamage> also called Rpi by some
2017-11-07T15:04:43 < dongs> rageberrypi
2017-11-07T15:04:44 < jadew> what does that account for?
2017-11-07T15:04:52 < BrainDamage> BrainDamage: the base-emitter junction has an intrinsic resistive behaviour
2017-11-07T15:04:56 < jadew> zyp, the challange is nice
2017-11-07T15:04:59 < BrainDamage> you're forward biasing a pn junction
2017-11-07T15:05:16 < BrainDamage> beta/gm is the linear approximation of the exp curve on the bias point
2017-11-07T15:07:53 < jadew> I'll have to look into that, cuz I don't understand it
2017-11-07T15:08:40 < BrainDamage> https://2.bp.blogspot.com/-bemFicfFoRw/UVz0kDkDuCI/AAAAAAAAAmk/LhyypCFTk6U/s1600/small+signal+diode2.bmp
2017-11-07T15:09:34 < BrainDamage> base-emitter is a diode, a diode is an exp, but having an exp is a pain in impedance calculations, so you take the tangent of the exp in the position where the static bias is
2017-11-07T15:10:03 < BrainDamage> and you get a linear i-v relationship, because that's what impedance is, a linear i-v relationship
2017-11-07T15:10:17 < BrainDamage> the coefficient of the tangent, has units of a resistance
2017-11-07T15:11:07 < jadew> why is it beta/gm?
2017-11-07T15:11:28 < BrainDamage> do the math and you'll know
2017-11-07T15:11:38 < jadew> I will, thanks
2017-11-07T15:12:38 < BrainDamage> this is often called 'small signal approximation'
2017-11-07T15:13:06 < BrainDamage> because as long as you don't move much from that bias point, you can pretend the exp is the tangent
2017-11-07T15:14:06 < sync> ah, that was my favorite semiconductor class
2017-11-07T15:20:33 < jadew> wish I was taking a class on these things
2017-11-07T15:21:00 < BrainDamage> there's plenty of online courses on this stuff, it's rather fundamental, also books

2017-11-07T15:21:46 < jadew> yeah, I want to fill the gaps I have in understanding analog design
2017-11-07T15:25:23 < jadew> I don't really need it, but it feels weird to use things you don't fully understand

2017-11-07T15:46:38 < karlp> needs more details
2017-11-07T15:46:51 < zyp> rmii plus standard phys or just phys?

2017-11-07T15:51:26 < c10ud> getting a big vendor would be better, I don't think I'm going to make thousands of pcbs, so I'll stick with microchip then I guess
2017-11-07T15:51:41 < dongs> that RTL looks like a winrar
2017-11-07T15:51:42 < zyp> dongs, 8893? yeah
2017-11-07T15:51:49 < c10ud> at least there's some kind of datasheet :D

2017-11-07T15:52:28 < zyp> basically
2017-11-07T15:53:06 < aandrew> realtek realwinning realgood
2017-11-07T15:53:37 < c10ud> uhhh I'm not really good at soldering those
2017-11-07T15:53:47 < c10ud> LQFP is better for me
2017-11-07T15:53:49 < c10ud> lol
2017-11-07T15:53:55 < aandrew> those aren't hard to solder. hot air man. a cheap hot air system is like $60
2017-11-07T15:53:59 < zyp> the shit I'm working on will have a bunch of devices chained, latency would be too high if every node needed to fully receive each packet before passing it on
2017-11-07T15:54:22 < aandrew> works fine for 4l although is a little slow with the exposed pad when it's solidly connected to an inner layer
2017-11-07T15:54:26 < sync> sounds like you need an ethercat device
2017-11-07T15:54:53 < zyp> sync, we opted for this solution because we don't want to pay for ethercat silicon
2017-11-07T15:54:54 < c10ud> I have it at home, but no time to master the youtube tecnique
2017-11-07T15:55:17 < karlp> who's the other cheapo network dude, are any still around other than realtek?
2017-11-07T15:55:24 < karlp> cirrus still do ethernet?
2017-11-07T15:55:27 < aandrew> what're you doing
2017-11-07T15:55:37 < aandrew> smsc (microchip) makes small switches IIRC
2017-11-07T15:56:03 < aandrew> I thought smsc, maybe micron? shit I can't remember whose switch I used
2017-11-07T15:56:08 < c10ud> yeah I'm oriented towards ksz8863
2017-11-07T15:56:15 < aandrew> micrel yes that's them
2017-11-07T15:56:21 < dongs> either that or chinaRTL are good choices
2017-11-07T15:57:31 < sync> zyp: ime the ethercat silicon is not that expensive
2017-11-07T15:57:34 < sync> and works
2017-11-07T15:57:48 < sync> I guess one could fiddle an fpga solution
2017-11-07T15:57:49 < c10ud> side question, did you ever try those 12V li-ion packs? same project, prototype runs on 12V pb but it feels...old
2017-11-07T16:00:13 < dongs> c10ud: you mean card lead-acid sized batt but li-ion?
2017-11-07T16:00:16 < dongs> card=car
2017-11-07T16:00:47 < c10ud> yep
2017-11-07T16:01:13 < c10ud> well, shape is not a problem though
2017-11-07T16:01:33 < c10ud> cost, as always, is
2017-11-07T16:01:44 < sync> > cost
2017-11-07T16:01:47 < dongs> just got one today
2017-11-07T16:01:52 < dongs> im pretty sure it cost way more than a leadacid one
2017-11-07T16:01:56 < c10ud> e.g. this would work https://www.ebay.com/itm/DC-12V-8000mAh-Super-Rechargeable-Portable-Lithium-ion-Battery-Pack-NEW-/182824402752
2017-11-07T16:01:58 < dongs> its a lot lighter tho
2017-11-07T16:02:07 < dongs> oh wut.
2017-11-07T16:02:08 < c10ud> 20$ is fine, 100$ is not

2017-11-07T16:06:49 < BrainDamage> lithium batteries don't tollerate abuse as much as lead acid
2017-11-07T16:07:17 < BrainDamage> you'll need at least low voltage cutoff

2017-11-07T16:07:20 < c10ud> yep, that's not an issue, I did a charger for a single cell before
2017-11-07T16:07:25 < dongs> yes, they fucking send current song position in BCD
2017-11-07T16:07:29 < c10ud> 12V however is different
2017-11-07T16:07:42 < c10ud> also prices of dongs' modules are too high for me
2017-11-07T16:08:02 < dongs> https://pastebin.com/GuAY1zhX
2017-11-07T16:08:16 < BrainDamage> that's because those are to power actual cars

2017-11-07T16:08:41 < sync> why are they sending the position in track
2017-11-07T16:08:42 < c10ud> i would be fine with chinese-like modules, just from a CEE approved salesman :)
2017-11-07T16:08:51 < dongs> sync, its satellite radio
2017-11-07T16:08:54 < dongs> so you know the song progress.
2017-11-07T16:09:04 < sync> yeah but why the fuck am I interested in that
2017-11-07T16:09:05 < sync> it is radio
2017-11-07T16:09:10 < sync> I cannot fast forward
2017-11-07T16:09:14 < dongs> haha so you can have a progress bar or someshit
2017-11-07T16:09:17 < dongs> but its clearly waht it is
2017-11-07T16:09:25 < BrainDamage> you can also sync a recorded that way

2017-11-08T00:45:08 < upgrdman> ahahaha fuck yes. one of the asshole tenants in area my office is in has been parking a huge trailer in the alley by us. we
2017-11-08T00:45:27 < upgrdman> we've complained to property management 3 times. they finally towed the trailer.
2017-11-08T00:45:56 < upgrdman> tenant comes in and asks if we've made any complaints. *poker face* "no"
2017-11-08T00:47:34 < upgrdman> i wonder how much the tow/impound fee for a trailor is. this was some huge ~30 foot (~10 meter) trailer.

2017-11-08T01:11:57 < upgrdman> damn. for a while i thought it was my shitty opengl code running slow on that surface bro 4. no, the gpu is just too weak when using a 4k monitor. even a fucking opengl hello-world-trianlge will peg GPU at >70% of the window is fullscreen. scrolling a static web page in chrome pegs the GPU at >75%.
2017-11-08T01:12:18 < tpw_rules> computers
2017-11-08T01:12:26 < tpw_rules> also in fairness that's 90% chrome's fault
2017-11-08T01:12:59 < upgrdman> and it seems to be the number of pixels that is the problem. e.g. rendering 500k GL_LINES versus rendering 1 GL_TRIANGLE has only a difference of maybe 10% GPU usage
2017-11-08T01:13:36 < upgrdman> tpw_rules, no this isnt chromes fault. intel integrated graphics just isnt meant to drive 4k60 for anything but the simplist of loads
2017-11-08T01:13:50 < upgrdman> like i said, even a hello-world-triangle has similar GPU loads
2017-11-08T01:14:02 < tpw_rules> > chrome has a light load
2017-11-08T01:14:25 < tpw_rules> sorry. i'm currently offended by the state of the web
2017-11-08T01:14:38 < upgrdman> also while looking at task manager, lolwut, when i *type* on my keyboard, the cpu usage goes from ~10% to ~38%
2017-11-08T01:15:07 < tpw_rules> that's probably another shitty surface bug
2017-11-08T01:15:18 < upgrdman> i guess spellcheck is super fucking demanding.
2017-11-08T01:15:21 < tpw_rules> my surface had a problem all thru 8 and 8.1 where unplugging the keyboard would peg it at 100%
2017-11-08T01:15:24 < tpw_rules> forever
2017-11-08T01:15:35 < upgrdman> im using a usb keyboard, not the touch cover
2017-11-08T01:16:28 < upgrdman> i *really* hope the next surface bro has usb-c for charging. i will immediately upgrade if they do. a little more power + being able to charge from a power bank would make my life so much nicer
2017-11-08T01:17:22 < tpw_rules> of course it will still only have 1
2017-11-08T01:18:06 < tpw_rules> usbc ime is garbage
2017-11-08T01:18:13 < tpw_rules> it might be apple's problem though
2017-11-08T01:18:39 < upgrdman> well ya i should rewrite that. if the new surface pro has a usb-c AND a usb-a, i will immediate upgrade
2017-11-08T01:18:50 < upgrdman> usb-a is still a requirement. apple is so fucking gay.
2017-11-08T01:19:31 < tpw_rules> no like the connectors are shit
2017-11-08T01:19:39 < tpw_rules> they're wiggly and disconnect if you breathe on them
2017-11-08T01:19:52 < tpw_rules> usb-a is crazy reliable
2017-11-08T01:19:55 < tpw_rules> usb-c isn't at _all_

2017-11-08T01:21:21 < tpw_rules> idk anyone else with usbc experience though
2017-11-08T01:22:57 < tpw_rules> have you
2017-11-08T01:23:52 < upgrdman> we'll i have not heard of any comments on it, but one of my coworkers has a usb-c phone and he's never bitched about it
2017-11-08T01:24:01 < upgrdman> but he might only be charging and not doing data xfer
2017-11-08T01:24:13 < upgrdman> are you using no name cables?
2017-11-08T01:24:33 < tpw_rules> well they're very name brand but idk how related to quality that is ;P
2017-11-08T01:25:13 < upgrdman> well i ask because for normal usb, i've had many cheap chinese cables become intermittent, both from the wire and from the connector
2017-11-08T01:25:20 < tpw_rules> no i understand
2017-11-08T01:25:26 < tpw_rules> but like afair it's always been this way
2017-11-08T01:25:35 < tpw_rules> i haven't had the computer that long. less than 1 year
2017-11-08T01:25:36 < upgrdman> ok

2017-11-08T01:27:31 < upgrdman> how annoying is the gay touch bar
2017-11-08T01:27:52 < tpw_rules> well i'm gay so it's perfect
2017-11-08T01:28:00 < upgrdman> figures
2017-11-08T01:28:03 < tpw_rules> idk i like it cause i have an app which lets me put arbitrary macros on it
2017-11-08T01:28:15 < upgrdman> but then you have to look at it :/
2017-11-08T01:28:23 < upgrdman> touch typing FTW
2017-11-08T01:28:29 < tpw_rules> i don't have to
2017-11-08T01:28:59 < tpw_rules> it also lets you get traditional function keys for apps that need em
2017-11-08T01:29:04 < tpw_rules> which no other laptop can do
2017-11-08T01:29:10 < tpw_rules> i do like the keyboard also. except it's unreliable

2017-11-08T01:29:30 < tpw_rules> answer: uh maybe?
2017-11-08T01:30:36 < upgrdman> no
2017-11-08T01:30:42 < upgrdman> just a screenshit of text
2017-11-08T01:31:25 < tpw_rules> yeah but imo you could construe it as gay porn
2017-11-08T01:34:54 < jadew> it's gay for sure
2017-11-08T01:34:58 < upgrdman> anything is if you try hard enough
2017-11-08T01:35:01 < jadew> and that guy is an idiot

2017-11-08T01:49:40 < jadew> yeah, I like it cuz it's more to the point, but I realize I'd be left with a bunch of questions if I didn't already knew the answer to them
2017-11-08T01:50:26 < jadew> for example on the section about the common emitter amplifier it doesn't say what actually makes a common emitter amplifier and it starts by presenting one with emitter degeneration
2017-11-08T01:50:53 < jadew> and that's the only one presented in that section :)

2017-11-08T02:28:23 < jadew> dr. pepper really
2017-11-08T02:36:03 < upgrdman> are romanians also the kind of faggots that call every type of soda "coke"
2017-11-08T02:36:39 < jadew> don't know, we don't call anything coke
2017-11-08T02:37:00 < jadew> I assumed you're the kind of faggots that do, so I used your language :D
2017-11-08T02:37:27 < jadew> we use the full name of each drink
2017-11-08T02:38:44 < upgrdman> ok good
2017-11-08T02:38:51 < upgrdman> in so cal at least, we use the fucking names too
2017-11-08T02:38:54 < jadew> tbh, didn't know coke can stand for anything other than coca cola
2017-11-08T02:39:06 < jadew> I was addicted to that too, but then I switched to dr. pepper
2017-11-08T02:39:10 < upgrdman> but some faggots on the east coast or south like to call everything coke. "i"

2017-11-08T06:02:46 < hesperaux> hi hi. Wondering if someone can advise me... I'm trying to build up a library of device "drivers" for various stuff. In some cases, this requires setting up interrupt handlers. As I'm using the standard peripheral library from ST, all of these interrupt vectors are pre-defined. There are specific function names for each interrupt source. How can I generalize this to allow for dynamic interrupt handling? Essentially, I am
2017-11-08T06:02:46 < hesperaux> thinking of modifying a function pointer that is called by these interrupt routines, but I'm not sure how to do this...
2017-11-08T06:03:30 < hesperaux> If that question made sense, can anyone give advice on creating a dynamic, "assignable from main()" type interrupt handling?
2017-11-08T06:06:05 < Thorn> either move the vector table into ram or call your actual handlers by pointer
2017-11-08T06:06:45 < Thorn> I've never needed it though, sounds like overengineering
2017-11-08T06:06:52 < hesperaux> Thorn, could you explain how the second bit would be done?
2017-11-08T06:07:09 < hesperaux> Thorn, the idea is to not have to create custom event handlers in every project that uses similar drivers/code
2017-11-08T06:07:38 < hesperaux> so far, the majority of the "driver" is portable, with the exception of the actual interrupt stuff
2017-11-08T06:08:30 < hesperaux> I haven't really used arduino much, but I think they have some sort of "attachInterrupt(myPointer)" thing
2017-11-08T06:12:50 < Thorn> void my_foo_handler() { ... } void (*my_foo_handler_ptr)() = &my_foo_handler; void Foo_IRQHandler() { my_foo_handler_ptr(); }
2017-11-08T06:15:21 < hesperaux> in order for the Foo_IRQHandler() to see my_foo_handler_ptr, that would have to be declared global and probably static right?
2017-11-08T06:15:55 < Thorn> global of course, static only if everything is in the same translation unit
2017-11-08T06:16:24 < hesperaux> ok
2017-11-08T06:16:53 < hesperaux> so from this, I would gain the ability to define which functions are called by each particular interrupt routine, which could mean calling the same function or unique ones...
2017-11-08T06:17:23 < hesperaux> that might work
2017-11-08T06:18:08 < hesperaux> the problem at hand is external edge triggered interrupts... I want to dynamically define what pins the code uses, but each pin has a different interrupt IRQHandler (or at least multiple groups of pins do)
2017-11-08T06:18:17 < Thorn> what I do is have the user implement the handler and call an appropriate method in a driver object: USBDev usbdev(...); void USB_IRQHandler() { usbdev.isr(); }
2017-11-08T06:18:52 < hesperaux> Thorn, is that a C++ object or a C object?
2017-11-08T06:18:59 < Thorn> c++ of course
2017-11-08T06:19:15 < hesperaux> all my code is in C at present - since I don't actually know C++ really
2017-11-08T06:19:38 < hesperaux> I just use structs to keep the data together
2017-11-08T06:20:13 < Thorn> well you can l earn enough to basically use classes as modules, it could be useful
2017-11-08T06:20:14 < hesperaux> I guess it doesn't matter much here though because I could just have a pointer in my struct for "isr" and call it just as you did there
2017-11-08T06:20:27 < Thorn> yes you can do that
2017-11-08T06:20:40 < hesperaux> Thorn, it's something i've thought of many times... I prefer OOP in general. I just don't know C++ specifically and haven't taken the time for it yet
2017-11-08T06:21:37 < Thorn> there's not much room for classic OOP in c++ embedded dev IMO
2017-11-08T06:21:44 < hesperaux> Thorn, in your scenario, would it be accurate to say that you subscribe your objects to IRQs by "registering them" within the IRQ handler (calling them)? So it would be up to that object to determine if it should process that interrupt right?
2017-11-08T06:21:51 < Thorn> for one thing it would imply the need for dynamic allocation
2017-11-08T06:22:01 < hesperaux> Thorn, that is part of the reason I've avoided it. I don't want to get carried away (and I usually do)
2017-11-08T06:22:57 < hesperaux> any chance you could share a small piece of code that demonstrates how you are doing it?
2017-11-08T06:23:00 < Thorn> the USBDev::isr() method will read the registers and decide what to do if anything
2017-11-08T06:23:02 < dongs> > I prefer OOP in general. I just don't know C++ specifically
2017-11-08T06:23:02 < dongs> what
2017-11-08T06:23:10 < dongs> what teh fuck do you use then
2017-11-08T06:23:24 < hesperaux> dongs, C#, Java, Python
2017-11-08T06:23:28 < dongs> gross
2017-11-08T06:23:30 < hesperaux> but not for embedded
2017-11-08T06:23:48 < dongs> C# was great in like 2005
2017-11-08T06:24:00 < dongs> they added so much retarded garbage into it its barely readable these days
2017-11-08T06:24:01 * hesperaux considers whether or not to debate about C#
2017-11-08T06:24:17 < dongs> everytime i see "auto faggot;" in C# code i want to murder

2017-11-08T06:25:28 < hesperaux> LINQ is quite nice, although I didn't use it too much
2017-11-08T06:25:32 < branjb> var is the most obnoxious data type ever
2017-11-08T06:25:44 < hesperaux> it's not really a data type, but sure
2017-11-08T06:25:50 < dongs> whats vaR?
2017-11-08T06:25:51 < dongs> like auto?
2017-11-08T06:25:51 < branjb> fine
2017-11-08T06:25:58 < hesperaux> it's just a lazy programming keyword
2017-11-08T06:26:00 < branjb> var is the most obnoxious variable declaration statement ever
2017-11-08T06:26:01 < branjb> yeah
2017-11-08T06:26:01 < dongs> i probably dont even wanna know
2017-11-08T06:26:10 < branjb> you can do
2017-11-08T06:26:15 < branjb> var poop = 0.001f;
2017-11-08T06:26:18 < hesperaux> I agree about var. I personally don't use it, and our team was against it
2017-11-08T06:26:18 < branjb> and it casts poop to a float
2017-11-08T06:26:24 < branjb> so you can just fill your code with
2017-11-08T06:26:30 < branjb> var poop, var penis, var butt
2017-11-08T06:26:36 < hesperaux> I find var to make code more confusing, not less
2017-11-08T06:26:40 < branjb> yeah
2017-11-08T06:26:45 < dongs> can you do var poop = 0.1f; and then poop = "nigger" and it works?
2017-11-08T06:26:49 < branjb> no
2017-11-08T06:26:53 < hesperaux> dongs, that would fail
2017-11-08T06:27:06 < hesperaux> hence why var is pointless - it doesn't do anything, it just makes it harder for you to self-enforce your typing
2017-11-08T06:27:12 < branjb> yeah
2017-11-08T06:27:17 < branjb> there are some good things about c#
2017-11-08T06:27:25 < branjb> but definitely not the fucking unreadable shit most people do
2017-11-08T06:27:40 < branjb> it's like people try to one up each other writing the most unreadable lines possible then whacking off to it
2017-11-08T06:27:49 < hesperaux> I haven't had a look around at other people's C# much, aside from the team at work (and we all had a coding standard to follow)
2017-11-08T06:27:59 < dongs> branjb: i suspect this is due to not actually knowing how to program
2017-11-08T06:28:02 < dongs> and just bruteforcing it
2017-11-08T06:28:07 < hesperaux> branjb, are you talking about the massive chains and super complex linq queries to do something on one line instead of 4 lines?
2017-11-08T06:28:09 < dongs> this is how dickstarterpals arduino code looks liek
2017-11-08T06:28:17 < Thorn> kotlin is best
2017-11-08T06:28:18 < Thorn> val x = if (y >= 0) x else -x
2017-11-08T06:28:25 < branjb> yeah, full of lambda expressions
2017-11-08T06:28:27 < Thorn> er val x = if (y >= 0) y else -y
2017-11-08T06:28:38 < hesperaux> I haven't done anything with kotlin. Lambda expressions have their use, but they are dangerous
2017-11-08T06:28:43 < branjb> i've been using the ? operator more recently
2017-11-08T06:29:01 < hesperaux> I feel like if not for the CLR taking care of it a lot of the time, C# code would run like shit because people don't think about how much code is generated by their source
2017-11-08T06:29:05 < dongs> < Thorn> er val x = if (y >= 0) y else -y
2017-11-08T06:29:07 < dongs> please die
2017-11-08T06:29:14 < hesperaux> haha
2017-11-08T06:29:16 < branjb> but mostly for shit like HAL_GPIO_WritePin(GPIOA, GPIO_PIN_8, steps < 0 ? GPIO_PIN_SET : GPIO_PIN_RESET);
2017-11-08T06:29:18 < Thorn> val foo = this.foo ?: return
2017-11-08T06:29:19 < hesperaux> dongs, you aren't very opinionated
2017-11-08T06:29:33 < dongs> not at all
2017-11-08T06:30:17 < hesperaux> I avoid ternaries cuz they confuse me most of the time. I have used them though
2017-11-08T06:30:35 < branjb> i only use in limited scenarios
2017-11-08T06:30:41 < branjb> above to me is justified
2017-11-08T06:30:58 < hesperaux> branjb, I think i've used basically the same line, except I don't use HAL
2017-11-08T06:30:59 < branjb> but no one else has to read my shitty embedded code
2017-11-08T06:31:02 < branjb> so i'll do w/e i want
2017-11-08T06:31:05 < hesperaux> hehe
2017-11-08T06:31:47 < branjb> HAL is dumb, but i do have to admit it kinda makes porting stuff around different micros a little easier
2017-11-08T06:31:49 < branjb> not much
2017-11-08T06:32:06 < hesperaux> right now I have #ifdef CORTEX_M4 in random places...it feels bad
2017-11-08T06:32:10 < branjb> but in certain limited cases it's not terrible
2017-11-08T06:32:37 < dongs> i may have to move a project from F401 to L4xx
2017-11-08T06:32:42 < hesperaux> how many of you guys are professional embedded devs?
2017-11-08T06:32:42 < dongs> dreading that it only has hal

2017-11-08T06:33:05 < dongs> hesperaux: stdperiphlib?
2017-11-08T06:33:07 < hesperaux> dongs, not today. But I believe that you are a protroll
2017-11-08T06:33:17 < hesperaux> dongs, I am surprised to hear that. I thought you would hate the SPL
2017-11-08T06:33:29 < hesperaux> you seem like a "I just include CMSIS" person
2017-11-08T06:33:45 < branjb> i'm surprised dongs doesn't just write inline assembly everywhere
2017-11-08T06:33:48 < hesperaux> branjb, professional as in you get paid to write code for microcontrollers, and you have a desk not in your house where you do this
2017-11-08T06:33:52 < hesperaux> lol
2017-11-08T06:34:02 < branjb> i guess i am
2017-11-08T06:34:07 < dongs> hesperaux: what if I get paid while doing it on the desk in my house
2017-11-08T06:34:12 < branjb> lol
2017-11-08T06:34:20 < hesperaux> dongs, in that case it depends on how often you get paid
2017-11-08T06:34:41 < hesperaux> also, if you get paid while doing it on the desk in your house, sounds more like prostitution :P

2017-11-08T06:34:55 < branjb> isn't that the dream
2017-11-08T06:35:00 < hesperaux> perhaps it is
2017-11-08T06:35:28 < branjb> dongs do you do contract work or just work remotely for a company?
2017-11-08T06:36:07 < hesperaux> I'm wondering if "professional" embedded engineers were trained in writing good quality code, and if so, from where were they trained...cuz I can't seem to find good resources on embedded *design* practices/patterns
2017-11-08T06:36:19 < dongs> hesperaux: yea no shit
2017-11-08T06:36:23 < dongs> try searching for "coding camps"
2017-11-08T06:36:27 < dongs> they're all fucking ruby/php/aids
2017-11-08T06:36:32 < hesperaux> exactly
2017-11-08T06:36:33 < dongs> like, you cant even fucking learn proper code anywhere
2017-11-08T06:36:35 < hesperaux> it's very frustrating
2017-11-08T06:36:47 < hesperaux> so far the only decent bit of reading I've found is a book that I think is from the early 90s lol
2017-11-08T06:36:48 < branjb> lol
2017-11-08T06:36:53 < branjb> yeah
2017-11-08T06:36:55 < hesperaux> of course, it's quite outdated now...I only read half the book
2017-11-08T06:36:58 < branjb> books are best source for embedded
2017-11-08T06:37:04 < branjb> imo
2017-11-08T06:37:08 < upgrdman> im hoping for a new edition of C++ in a Nutshell that'll cover cpp17. or at least cpp14.
2017-11-08T06:37:12 < hesperaux> any books you would recommend? I've been searching but not sure what to pull trigger on
2017-11-08T06:37:20 < hesperaux> hi upgrdman
2017-11-08T06:37:23 < upgrdman> hi
2017-11-08T06:37:36 < upgrdman> ya im looking ofr a good cpp book too
2017-11-08T06:37:58 < hesperaux> glad to hear I'm not the only one at least
2017-11-08T06:38:10 < branjb> i read https://www.amazon.com/gp/product/1466468866/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 recently
2017-11-08T06:38:12 < upgrdman> theyre all either aimed at noobs that doing the the different between if() and while(), or theyre dry boring books by bjarne
2017-11-08T06:38:17 < branjb> it gave me more to think about
2017-11-08T06:38:25 < hesperaux> upgrdman, seems about right, yeah
2017-11-08T06:39:25 < sync> I know some pro c++ magician that knows the bjarne books by heart
2017-11-08T06:39:27 < hesperaux> branjb, hmm, I haven't dove into using OSs yet. It's on my todo list though
2017-11-08T06:39:59 < branjb> the concepts translate well to regular OS less embedded
2017-11-08T06:40:05 < branjb> or the reasoning behind concepts
2017-11-08T06:40:13 < branjb> to me that's the hard part to teach
2017-11-08T06:40:26 < branjb> or learn
2017-11-08T06:40:59 < sync> hesperaux: the question is what is an embedded engineer to you?
2017-11-08T06:41:04 < branjb> here's a good one for dongs: https://www.amazon.com/Exploring-Arduino-Techniques-Engineering-Wizardry/dp/1118549368/ref=sr_1_2?ie=UTF8&qid=1510116053&sr=8-2&keywords=arduino+book&dpID=51eg%252BJKsuQL&preST=_SX218_BO1,204,203,200_QL40_&dpSrc=srch
2017-11-08T06:41:10 < dongs> dmpty
2017-11-08T06:41:13 < dongs> snort
2017-11-08T06:41:41 < dongs> lemme guess
2017-11-08T06:41:44 < dongs> one of the chapters
2017-11-08T06:41:45 < hesperaux> sync, fair enough... In this context, I'd say it's someone that writes code for products using C or C++ on a microcontroller without a full-fledged OS (not linux, not android...etc)
2017-11-08T06:41:57 < dongs> "Making digitalRead() 100 times faster! The results will shock you!"
2017-11-08T06:42:02 < hesperaux> branjb, lol
2017-11-08T06:42:03 < branjb> what about for vxworks
2017-11-08T06:42:25 < hesperaux> My best friend uses vxworks - I've never touched it so don't know
2017-11-08T06:42:26 < upgrdman> branjb, cute. notice how that book about an 8bit MCU has... 255 reviews? lol
2017-11-08T06:42:38 < branjb> lol
2017-11-08T06:42:47 < branjb> (((coincidence)))
2017-11-08T06:42:48 < hesperaux> upgrdman, mind blown
2017-11-08T06:43:15 < sync> illuminati confirmed
2017-11-08T06:43:27 < dongs> i should write a negative review and overflow the counter
2017-11-08T06:43:31 < branjb> lol
2017-11-08T06:43:40 < hesperaux> dongs, maybe it will just go down to 254?
2017-11-08T06:44:16 < branjb> lmao ~more about the author~: https://imgur.com/a/N0IOH
2017-11-08T06:44:23 < branjb> looks like a hacker/maker
2017-11-08T06:44:58 < dongs> fucking newfag
2017-11-08T06:45:10 < hesperaux> I don't know, master's and BS at cornell beats my ass
2017-11-08T06:45:28 < branjb> I was trying to find grad year
2017-11-08T06:45:35 < dongs> yesterday
2017-11-08T06:45:58 < branjb> university education damn near garbage, at least where i went
2017-11-08T06:46:15 < branjb> although I probably learned way more on my own because I got pissed at how useless it was
2017-11-08T06:46:20 < hesperaux> branjb, I would say it depends on how people make use of it
2017-11-08T06:46:22 < upgrdman> branjb, he has an youtube channel.
2017-11-08T06:46:24 < branjb> than if they had spoon fed me
2017-11-08T06:46:39 < upgrdman> i sub'd to him back when i found out about the arduino
2017-11-08T06:46:48 < branjb> hahaha
2017-11-08T06:46:51 < dongs> lol
2017-11-08T06:47:10 < upgrdman> he videos were ok, but he just seemed like a college kids fucking around in his parents basement
2017-11-08T06:47:20 < hesperaux> upgrdman, sub'd him back? What, you have a channel?
2017-11-08T06:47:27 < hesperaux> you guys are basically describing me right now
2017-11-08T06:47:27 < dongs> yeah
2017-11-08T06:47:30 < dongs> hes a pro arduino troll
2017-11-08T06:47:39 < upgrdman> back when i found out about arduinos
2017-11-08T06:47:40 < upgrdman> as in
2017-11-08T06:47:44 < upgrdman> a long fuckin time ago
2017-11-08T06:47:56 < branjb> EE and CpEs graduated my college without ever knowing anything about embedded more than arduino
2017-11-08T06:47:56 < upgrdman> but yes, hesperaux, i have a yt channel as well.
2017-11-08T06:48:16 < upgrdman> mostly boring stuff trying to SEO for makers. because ad revenue.
2017-11-08T06:48:19 < branjb> if you can't arduino IDE import sparkfun library, it's not possible
2017-11-08T06:48:44 < hesperaux> the arduino IDE is probably why I've never tried to make a project with one
2017-11-08T06:48:49 < hesperaux> also feels like cheating
2017-11-08T06:48:51 < dongs> "IDE"
2017-11-08T06:48:56 < hesperaux> yeah =\
2017-11-08T06:48:58 < dongs> you simply cannot even call it that
2017-11-08T06:49:03 < upgrdman> what a sorry excuse for an ide
2017-11-08T06:49:03 < dongs> by any stretch of hte word
2017-11-08T06:49:05 < hesperaux> it's a text editor
2017-11-08T06:49:09 < hesperaux> a bad one
2017-11-08T06:49:11 < dongs> a fucking awful text editor
2017-11-08T06:49:13 < upgrdman> a BAD text editor
2017-11-08T06:49:16 < hesperaux> lol
2017-11-08T06:49:17 < branjb> upgrdman I basically am stealing all your ideas from your balancing robot, I'm gonna make a similar gimbaled remote
2017-11-08T06:49:37 < upgrdman> tab == 2 spaces. that right there tells you all you need to know about the arduino ide.
2017-11-08T06:49:44 < hesperaux> upgrdman, lol'd
2017-11-08T06:49:51 < branjb> do you think they make it bad on purpose?
2017-11-08T06:49:58 < hesperaux> i really don't know
2017-11-08T06:50:00 < dongs> branjb: http://www.mxchip.com/az3166 switch straight to this
2017-11-08T06:50:03 < sync> upgrdman: have you ever tried playing around with the gyro position on your bot?
2017-11-08T06:50:05 < upgrdman> branjb, cool. have fun.
2017-11-08T06:50:05 < hesperaux> I have often wondered why ti's so bad
2017-11-08T06:50:13 < hesperaux> to keep it "simple"?
2017-11-08T06:50:19 < hesperaux> or because platform.io exists?
2017-11-08T06:50:20 < upgrdman> sync, not really, why
2017-11-08T06:50:37 < hesperaux> speaking of IDEs, are you guys all vi people or will you actually use an IDE?
2017-11-08T06:50:44 < dongs> keil 4 lyfe
2017-11-08T06:50:45 < branjb> dongs: I still can't even tell you what IoT means
2017-11-08T06:50:56 < hesperaux> branjb, it's internet onto things
2017-11-08T06:51:02 < branjb> k, what's that
2017-11-08T06:51:03 < upgrdman> hesperaux, i use eclipse.
2017-11-08T06:51:05 < sync> because you get superior results when it is in line with your motors axis of rotation
2017-11-08T06:51:20 < upgrdman> sync, thats what im doing :)
2017-11-08T06:51:20 < hesperaux> branjb, it's like when you have the internet and things do stuff
2017-11-08T06:51:29 < hesperaux> branjb, also it has to create security holes in your network
2017-11-08T06:51:43 * hesperaux personally likes using EmBitz
2017-11-08T06:51:45 < dongs> so you can turn on your bathroom lights while driving on highway in another country
2017-11-08T06:51:52 < branjb> the best example of IoT i can think of is when your fridge refuses to open for you and then calls you fat
2017-11-08T06:51:59 < hesperaux> I tried to get JetBrains' CLion to work, but had some issues with the linker and gave up
2017-11-08T06:52:26 < branjb> so IoT means things that are connected to the world wide web for no reason?
2017-11-08T06:52:36 < dongs> yes
2017-11-08T06:52:38 < hesperaux> branjb, correct, especially with a web server
2017-11-08T06:52:46 < branjb> hmmm
2017-11-08T06:52:48 < dongs> absolutely no reason is the most important part
2017-11-08T06:52:50 < branjb> IoT toilette
2017-11-08T06:52:51 < hesperaux> most of the time, the product features from IoT are gimicks
2017-11-08T06:52:59 < hesperaux> sometimes they are useful though
2017-11-08T06:53:01 < branjb> "your poop says you should see a doctor soon"
2017-11-08T06:53:16 < hesperaux> however, I'd rather it be the "private secure network of things for your home only"
2017-11-08T06:53:26 < dongs> thats why wires exist
2017-11-08T06:53:38 < hesperaux> dongs, c'mon, you know that's not entirely fair
2017-11-08T06:53:46 < hesperaux> adding wires everywhere is a pain in the ass
2017-11-08T06:54:09 * hesperaux recently put a cat6 into the basement through horrid filth and insects
2017-11-08T06:54:19 < branjb> gross
2017-11-08T06:54:23 < hesperaux> it was quite
2017-11-08T06:54:33 < upgrdman> sync, this is my previous rebot, but you can see the sensors between the servos. in line with the "axel" http://www.farrellf.com/temp/robot_pre_pcb.jpg
2017-11-08T06:54:51 < branjb> that looks like tasty spaghetti
2017-11-08T06:55:00 < hesperaux> upgrdman, I like that is has a USB port
2017-11-08T06:55:05 < hesperaux> are those erector set wheels?
2017-11-08T06:55:15 < upgrdman> usb port is just for power
2017-11-08T06:55:16 < sync> yeah, that is pretty good
2017-11-08T06:55:19 < hesperaux> omg it's welded
2017-11-08T06:55:20 < branjb> those wheels didn't work
2017-11-08T06:55:24 < branjb> i watched his video
2017-11-08T06:55:29 < upgrdman> and those wheels are from a toy rc airplane
2017-11-08T06:55:31 < sync> lots of those camera gimbals have the imu at shitty places
2017-11-08T06:55:31 < hesperaux> you welded this?
2017-11-08T06:55:33 < dongs> is that fucking welded?
2017-11-08T06:55:38 < dongs> lo'
2017-11-08T06:55:38 < sync> no
2017-11-08T06:55:40 < sync> it is soldered

2017-11-08T07:07:23 < upgrdman> solder is very strong if you use it like a thin glue. its weak if you use it like a gap filling glue.
2017-11-08T07:07:26 < branjb> lmao @ 17:06 trying to hold that piece on without burning yourself
2017-11-08T07:07:45 < sync> hesperaux: lots of things are soldered
2017-11-08T07:07:48 < sync> and they are strong
2017-11-08T07:07:56 < hesperaux> sync, not with circuit solder

2017-11-08T09:55:08 < sync> fest: it is
2017-11-08T09:55:14 < zyp> in the norwegian model, when a VAT-registered company sells anything, they have to charge VAT on the full price
2017-11-08T09:55:28 < hesperaux> crt, UA741 bro
2017-11-08T09:55:30 < sync> but they make use of the scheme that they claim it was taxed at import
2017-11-08T09:55:45 < sync> and the importing company claims that it will be taxed at sale
2017-11-08T09:55:55 < zyp> when a VAT-registered company buys anything, they pay VAT to the seller, then get it refunded
2017-11-08T09:55:55 < sync> so they evade that pretty well
2017-11-08T09:56:06 < sync> or they don't pay vat
2017-11-08T09:56:16 < sync> as they just would get it back anyway
2017-11-08T09:57:00 < sync> which is the trick
2017-11-08T09:57:29 < hesperaux> crt, watching this for now...wat
2017-11-08T09:57:51 < zyp> no, it's for school kids
2017-11-08T09:58:03 < zyp> at least that's my impression
2017-11-08T09:58:14 < zyp> we used multisim in high school, haven't used it since
2017-11-08T09:58:21 < hesperaux> lol
2017-11-08T09:58:29 < hesperaux> i've never used it
2017-11-08T09:58:52 < fest> zyp: but this company should be paying VAT when they import something from non-EU countries
2017-11-08T09:59:02 < hesperaux> this is a weird video
2017-11-08T09:59:04 < zyp> fest, why?
2017-11-08T09:59:42 < hesperaux> he wastes a lot of paper
2017-11-08T10:00:04 < fest> well, it happens like that in my country- for customs to clear non-EU imports, you have to submit proof that VAT and duties are paid
2017-11-08T10:00:34 < zyp> how about domestic trade?
2017-11-08T10:02:19 < zyp> anyway, let's say a company buys something for $100, processes it and sells it for $200
2017-11-08T10:02:50 < zyp> the norwegian standard VAT rate is 25% and that makes for fairly round numbers to calculate with, so let's use that
2017-11-08T10:03:20 < zyp> the base product with VAT would have a cost of $125, the end product will have a cost of $250
2017-11-08T10:04:36 < zyp> since it's a "value added" tax, and the added value is $100, your company should in sum charge a VAT of $25
2017-11-08T10:05:30 < zyp> but for complex assemblies or whatever it's not feasible to keep track of the original cost of the BOM or whatever to calculate how much value you've added
2017-11-08T10:05:50 < ohsix> multisim is q t
2017-11-08T10:05:59 < zyp> so instead, you get a refund for VAT on incoming stuff, and charge VAT on the full value of outgoing stuff
2017-11-08T10:06:07 < ohsix> all of my electronics magazines from the 90s are full of quaint ads about it
2017-11-08T10:06:33 < zyp> so when you pay $125 for something, you get a $25 refund and when you sell something for $200 you add a full $50 in VAT charge
2017-11-08T10:06:47 < zyp> and since $50 - $25 is $25, the end result is the same
2017-11-08T10:07:41 < zyp> this essentially means that a company doesn't pay VAT on anything it buys
2017-11-08T10:08:21 < zyp> either because you get a refund, or because the previous seller short circuits the process and doesn't charge it
2017-11-08T10:09:01 < zyp> in Norway, the former case is the usual, but I think it can be short circuited
2017-11-08T10:09:08 < zyp> under some conditions
2017-11-08T10:09:22 < zyp> this naturally also applies to imports
2017-11-08T10:09:43 < zyp> when something is imported, VAT is due, but since it's a company importing, VAT is refunded
2017-11-08T10:09:55 < qyx> here we usually buy without vat in this cse
2017-11-08T10:10:13 < zyp> and this could be short circuited by just not charging the VAT on the import
2017-11-08T10:10:24 < zyp> since it'll be charged in full when the company sells the product anyway
2017-11-08T10:10:45 < zyp> either way, end result is the same
2017-11-08T10:11:51 < zyp> also, the way I understand VAT handling in the EU is that you pay VAT according to the rate in the sellers country, not the buyers
2017-11-08T10:12:23 < zyp> i.e. seller charge VAT like usual, buyer's country does no further customs processing
2017-11-08T10:13:00 < zyp> but I might be wrong on that, since I'm not in EU myself
2017-11-08T10:14:24 < fest> ok, nice explanation, but how do they manage to sell without charging VAT?
2017-11-08T10:15:33 < ohsix> gummel poon
2017-11-08T10:15:46 < fest> at least here, asking for VAT refund directly (money in company bank account) has very strong correlation with asking for audit (because of widespread VAT fraud schemes)
2017-11-08T10:16:11 < zyp> fest, I figure they don't, they just sell it from a EU country with a low VAT rate
2017-11-08T10:16:30 < fest> so companies usually cover other taxes they owe with the "refunded VAT"
2017-11-08T10:17:00 < fest> are there countries with less than 15-20% VAT rate in EU?
2017-11-08T10:17:06 < zyp> idk
2017-11-08T10:17:39 < fest> hmm, Switzerland has 8% standard rate?

2017-11-08T13:21:45 < zyp> at least they don't use it like people normally do
2017-11-08T13:22:53 < zyp> instead of a .data-section with LMA pointing to init-data in flash and VMA pointing to the data area in ram, their .data-section just points to ram, just like .bss
2017-11-08T13:23:11 < dongs> why would anyoen ever care about this
2017-11-08T13:23:15 < zyp> and then they have a separate .cinit-section in flash with the init contents

2017-11-08T15:25:58 < qyx> just 4 letters
2017-11-08T15:31:19 < dongs> can someone explain me what the actual fuck a "yield" is (that isnt about rtos timeslicese)
2017-11-08T15:31:39 < dongs> apparently its some bullshit construct in C# and pythoon(GAY) but i have no fucking clue what it acutallty does
2017-11-08T15:32:50 < zyp> it's similar to what it does in a RTOS
2017-11-08T15:32:56 < dongs> .. no
2017-11-08T15:33:00 < zyp> except it doesn't yield from a thread, it yields from a coroutine
2017-11-08T15:33:50 < dongs> anything trying to explain it ends up being about miles of garbage unreadable python code
2017-11-08T15:34:03 < dongs> mylist = [x*x for x in range(3)] (from stackoverflow)
2017-11-08T15:34:12 < dongs> fucking LOL @ that syntax, how can ANYONE understand what it does?
2017-11-08T15:34:27 < dongs> its liek fuck you, we'll jsut pile all t he shit into one line because reasons
2017-11-08T15:34:29 < zyp> what's the context? in python it's basically used for generators or async stuff
2017-11-08T15:34:33 < zyp> I mean, yield is
2017-11-08T15:34:41 < dongs> no ,i just saw it in some code and it made no sense
2017-11-08T15:34:49 < dongs> but thats business as usaul for any ptython code
2017-11-08T15:35:19 < qyx> you don't have to write such constructs
2017-11-08T15:35:22 < qyx> it is just a shortcut
2017-11-08T15:35:24 < zyp> you can think of it as a return statement, that allows the caller to resume the function later from that point
2017-11-08T15:35:34 < dongs> how would you "resume" it
2017-11-08T15:35:38 < dongs> by calling same function again?
2017-11-08T15:36:08 < zyp> no
2017-11-08T15:36:38 < dongs> then it makes no sense
2017-11-08T15:36:50 < dongs> unless thre's some kinda 'join' that goes back to the left off shit
2017-11-08T15:36:53 < zyp> calling a function like that gives you a generator object, the generator-object has a next()-method that runs until next yield point and gives you the yielded value
2017-11-08T15:37:09 < karlp> I love those list comprehensions
2017-11-08T15:37:09 < dongs> anywho, time to stop giving a fuck about python, will never undertand the insanity of that langauge
2017-11-08T15:37:13 < karlp> but yeah, I found them odd at first.
2017-11-08T15:37:14 < zyp> i.e. the generator object holds the state (stack frame) for that function
2017-11-08T15:37:30 < dongs> karlp: i think you forgot to prefix "in"

2017-11-08T15:37:58 < Thorn> you can also do mylist = (x*x for x in range(3))

2017-11-08T15:39:32 < zyp> would have been nice, you can do neat async stuff with it
2017-11-08T15:39:40 < dongs> Coroutines are computer-program components that generalize subroutines for non-preemptive multitasking, by allowing multiple entry points for suspending and resuming execution at certain locations.

2017-11-08T17:06:38 < dongs> does PCI needs +12/-12V??
2017-11-08T17:07:55 < englishman> oldpci?
2017-11-08T17:07:59 < englishman> i think not
2017-11-08T17:08:39 < englishman> just AGP
2017-11-08T17:10:36 < dongs> checked pinout apparently it does
2017-11-08T17:10:42 < dongs> i doubt any cards actualyl "need" it

2017-11-08T17:12:22 < zyp> okay, there's one thing that's easier on cortex-r than cortex-m

2017-11-08T17:13:09 < zyp> since cortex-r doesn't set up $sp in hardware, startup code must do it, which means bootloader doesn't have to do it when jumping to app
2017-11-08T17:13:12 < sync> dongs: when you need your fast RAMDAC for 4k VGA output
2017-11-08T17:13:23 < dongs> heh
2017-11-08T17:14:06 < zyp> bad thing is, there's nothing equivalent to SCB_VTOR
2017-11-08T17:14:09 < karlp> zyp: how does that make anything "easier" ?
2017-11-08T17:15:01 < dongs> saves one instrcution
2017-11-08T17:15:12 < zyp> karlp, no need to asm("mov $sp, blah; b app_main"); can just do app_main();
2017-11-08T17:15:28 < dongs> i've never done asm() in my code
2017-11-08T17:15:34 < dongs> if there isnt a cmsis intrinsic for it, you shouldnt be using it
2017-11-08T17:15:46 < dongs> compiler knows better than you, WAY better

2017-11-08T17:16:35 < zyp> I don't trust compiler to not push anything after setting stack pointer, before calling app_main
2017-11-08T17:16:57 < dongs> well, you ARE using gcc after all
2017-11-08T17:17:02 < dongs> i wouldnt even trust it to generate working code.
2017-11-08T17:17:10 < karlp> the compiler intrinsics are normally just wrappers around asm anyway
2017-11-08T17:17:40 < englishman> the entire c language is a wrapper around asm
2017-11-08T17:17:50 < zyp> it'd be working anyway, you'll just have some garbage on the stack that waste space forever
2017-11-08T17:19:54 < zyp> and it's not a compiler thing, it's a question of whether your code has any variables in caller-save registers before the call
2017-11-08T17:20:00 < zyp> because then they'd have to be saved
2017-11-08T17:25:46 < englishman> dongs, has teh LP129QE1 supply dried up

2017-11-08T18:09:09 < upgrdman> in android, one app cant see anything about another app, right?

2017-11-08T18:10:18 < upgrdman> but other than that, no?
2017-11-08T18:10:40 < upgrdman> im tempted to hack together a simple password manager and want to make sure other apps cant see my "code" or data.
2017-11-08T18:11:17 < Thorn> there are even apis to notify you when a new app is installed
2017-11-08T18:11:50 < Thorn> read up on storage in android. there is private storage that should be inaccessible by other apps

2017-11-08T20:47:02 < upgrdman> in windows task manager, cpu usuage, "kernel times" include shit like contention right? e.g. if kernel times are high, there might be problems with io latency, lock contention, etc. ?
2017-11-08T20:47:12 < upgrdman> cache misses, etc.
2017-11-08T20:51:22 < Ultrasauce> its not a super useful metric because there is such a wide variety of stuff that happens in syscalls
2017-11-08T20:51:34 < upgrdman> sure
2017-11-08T20:51:38 < Ultrasauce> i bet waiting for vsync is included in there if you're talking about your thing
2017-11-08T20:51:52 < upgrdman> but it a lot of the cpu chart is kernel times, thats a "bad" thing usually, right?
2017-11-08T20:52:07 < upgrdman> e.g. just doing ass loads of math should result is ~0% kernel times?
2017-11-08T20:52:18 < upgrdman> ahh. ok
2017-11-08T20:52:24 < upgrdman> yes im talking about my thing.
2017-11-08T20:53:27 < Ultrasauce> gpu profiling is a bit of a can of worms
2017-11-08T20:54:23 < upgrdman> actually right now i think im cpu bound. i suppose i should stop being lazy and actually use FFTs instead of DFTs for my frequency domain chart.
2017-11-08T20:54:38 < Ultrasauce> fftw
2017-11-08T20:54:45 < upgrdman> i just fell bad about using algorithms that i dont quite understand
2017-11-08T20:55:14 < upgrdman> guess i should plop down on the couch and watch an assload of fft vids on youtube and hope something sinks in
2017-11-08T20:55:53 < Ultrasauce> i am of the opinion that that sort of thing is always going to be done better by someone else
2017-11-08T20:56:10 < Ultrasauce> unless you spend months and months on r&d for that specific thing
2017-11-08T20:56:24 < upgrdman> ya im happy to use a lib. i just feel bad when i use a lib and dont understnad what its doing for me
2017-11-08T20:56:36 < Ultrasauce> I mean I definitely identify with the desire to pull everything together from scratch
2017-11-08T20:58:03 < Ultrasauce> the short version i think is the fft exploits periodicity and shannon-nyquist to apply divide-and-conquer optimizations to the naive dft
2017-11-08T20:58:17 < Ultrasauce> where lower frequencies require less samples to measure, etc

2017-11-09T02:10:42 < DelvingDeeper> Remember my lecturer saying the most important rule and the biggest time saver is RTFM: Read The Fuckin Manual. Honestly the best advice I've gotten
2017-11-09T02:11:32 < DelvingDeeper> On a side note how common/important is ASM programming in industry when it comes to embedded design?
2017-11-09T02:12:01 < englishman> it's solid advice
2017-11-09T02:12:18 < englishman> depends your industry i guess
2017-11-09T02:12:44 < englishman> i don't think you need a mastery, but knowledge of asm makes for a good c programmer
2017-11-09T02:13:34 < DelvingDeeper> englishman: Definitely thinking that, seems like it would be a great way to speed up time sensitive projects. The C compiler seems to add a large overhead on the code
2017-11-09T02:13:48 < DelvingDeeper> especially HAL
2017-11-09T02:14:17 < englishman> well i'm not saying you should actually program in asm
2017-11-09T02:14:52 < englishman> that's just wasting time
2017-11-09T02:14:58 < DelvingDeeper> Englishman: hmm.. so knowledge of it is important not the ability to write all your code in asm. Assuming that would make a project very legthy

2017-11-09T03:43:41 < branjb> it seems simple
2017-11-09T03:44:08 < branjb> the idea i had was to grab 22.2ms of signal, the frame length
2017-11-09T03:44:12 < branjb> figure out where the start was
2017-11-09T03:44:25 < branjb> then just sync a timer to always grab 22.2ms at each start time
2017-11-09T03:44:29 < branjb> is that the wrong approach?

2017-11-09T04:08:21 < DelvingDeeper> If I have a timer setup in slave mode: trigger mode and the channel 1 of that timer set on input capture, does it mean the timer won't execute an input capture until the trigger source has gone high?

2017-11-09T10:25:00 < dongs> hm after actually doing the layout th at makes sense, I think i like this SY stuff
2017-11-09T10:25:08 < dongs> and they're like 4x cheaper than onsemi
2017-11-09T10:25:22 < dongs> for same parts count
2017-11-09T10:35:17 < zyp> "retarded, retarted, o wait it's actually nice"
2017-11-09T10:37:04 < dongs> ^_^
2017-11-09T10:37:35 < zyp> what part looked retarded? FB being on opposite corner from LX?
2017-11-09T10:38:09 < zyp> it'd probably be nicer with FB and EN swapped
2017-11-09T10:38:38 < zyp> but idk, routing a five pin part can't be that hard, regardless of what pinout it has
2017-11-09T10:39:08 < dongs> no it ended up being really nice
2017-11-09T10:39:32 < dongs> https://i.imgur.com/jpmxOJe.png
2017-11-09T10:39:52 < dongs> fb opposite made sense to allow for R+C there
2017-11-09T10:40:11 < zyp> ah, neat
2017-11-09T10:40:39 < zyp> but still, swapping FB and EN wouldn't make that any worse

2017-11-09T11:25:51 < karlp> zyp: datasheet says to keep the FB network as far away from LX pin as possible, so better where it is vs swapped with EN.
2017-11-09T11:26:04 < zyp> heh

2017-11-09T14:16:28 < DelvingDeeper> Does anyone know how to use the reset mode of the timer for a falling edge? Seems hard wired to a rising, but I just feel there must be a way >.<
2017-11-09T14:17:35 < qyx> and whats your trigger output?
2017-11-09T14:18:01 < qyx> wait, what.. are you resetting the timer by another master timer?
2017-11-09T14:18:07 < dongs> yeah
2017-11-09T14:18:09 < dongs> thats what he s doing
2017-11-09T14:18:16 < qyx> because theres also the etr
2017-11-09T14:19:39 < qyx> when resetting on a compare event, switching the mode to pwm2 should do the trick, shouldn't it?
2017-11-09T14:19:53 < qyx> other modes don't seem relevant (on enable, on update, etc)

2017-11-09T14:26:12 < DelvingDeeper> qyx: The falling edge of the DRDY signal lets my system know new data will be incoming. i want this to reset the counter and then have the counter go to lets say 96 counts for the 96 bits I'll be receiving

2017-11-09T14:26:35 < dongs> wait waht is this shit
2017-11-09T14:26:51 < dongs> what are you even trying to do
2017-11-09T14:27:03 < dongs> just use two spi channels
2017-11-09T14:27:09 < dongs> clock both from same shit
2017-11-09T14:27:12 < dongs> DMA that stuff
2017-11-09T14:27:17 < dongs> why are you fucking aroudn wiht tmers
2017-11-09T14:27:33 < DelvingDeeper> dongs: oh no... I'm letting the timer do the dma request..
2017-11-09T14:27:36 < dongs> or maybe even QSPI if you can run it in 2bit mode, or if not, just do 4 bit and ignore the rest
2017-11-09T14:28:30 < qyx> wut
2017-11-09T14:28:34 < qyx> yes, use spi
2017-11-09T14:28:51 < DelvingDeeper> I don't think I'll be able to do this in SPI mode, the adc runs in master. It says spi not supported in the mode I'm using it
2017-11-09T14:28:58 < dongs> what
2017-11-09T14:29:06 < dongs> use SPI to clock the data in
2017-11-09T14:29:11 < dongs> not as acutal "spi"
2017-11-09T14:29:20 < qyx> just the spi peripheral
2017-11-09T14:29:22 < qyx> not spi as bus
2017-11-09T14:29:30 < qyx> ie. abuse it to clock data in
2017-11-09T14:29:50 < dongs> i've abused SPI before to clock in mpeg2ts from digital tv tuner
2017-11-09T14:29:56 < DelvingDeeper> Ah I get what you mean. use the "spi"
2017-11-09T14:30:18 < DelvingDeeper> This might solve a lot of my problems..
2017-11-09T14:30:31 < dongs> youre surely not trying to get this data in as timer pulseas re you
2017-11-09T14:30:39 < DelvingDeeper> Timers get crazy with this sorta thing
2017-11-09T14:30:46 < dongs> because thats about as dumb as it sounds
2017-11-09T14:31:01 < DelvingDeeper> no I'm just letting the timer trigger DMA requests and then reading in 16 GPIO pins to memory
2017-11-09T14:31:42 < dongs> .
2017-11-09T14:31:50 < dongs> and ignoring all but 2 bits?
2017-11-09T14:32:05 < DelvingDeeper> ignoring all but 2 bits?
2017-11-09T14:32:22 < dongs> is tehre 0..15 DOUT or just DOUT0/1?
2017-11-09T14:32:38 < DelvingDeeper> Oh sorry using a SIPO shift register to shift it
2017-11-09T14:33:03 < dongs> damn thats some serious autism
2017-11-09T14:33:06 < dongs> SPI literally does that for you
2017-11-09T14:33:10 < dongs> for free
2017-11-09T14:33:32 < dongs> i mean i suppose this would work but damn youve been at it for weeks nwo
2017-11-09T14:33:38 < DelvingDeeper> Yeah I realize that now...
2017-11-09T14:34:02 < DelvingDeeper> I was following an app note and went down a loop hole
2017-11-09T14:35:18 < DelvingDeeper> asked on an stm forum and was provided with an app note by a mod
2017-11-09T14:35:20 < DelvingDeeper> ]fml
2017-11-09T14:35:34 < dongs> mod, more like troll
2017-11-09T14:36:15 < DelvingDeeper> nah defs a mod, just wasted a good two weeks
2017-11-09T14:38:41 < DelvingDeeper> Here it is: http://www.st.com/content/ccc/resource/technical/document/application_note/7a/88/df/e3/d3/36/40/29/DM00169730.pdf/files/DM00169730.pdf/jcr:content/translations/en.DM00169730.pdf
2017-11-09T14:39:19 < dongs> sure, i mean its an appnote about doing dumb shit, not an appnote about reading your ADC
2017-11-09T14:39:58 < dongs> there seems to be DOUT0..7
2017-11-09T14:40:11 < dongs> are you only intersted in 2 channels then?
2017-11-09T14:40:23 < dongs> cuz the SPI method doesnt scale
2017-11-09T14:40:30 < dongs> are you sure it cant output in pareallel model?
2017-11-09T14:40:38 < DelvingDeeper> Dongs: There is but I'm daisy chaining, it has an SPI mode, but it's not allowed when you daisy chain, I'm coupling three of these ADC's together
2017-11-09T14:41:07 < dongs> oic, up to 3 can be chained
2017-11-09T14:41:22 < dongs> or 2
2017-11-09T14:41:30 < dongs> no, 3
2017-11-09T14:41:35 < DelvingDeeper> Yip, daisy chaining 3 for 24 channels
2017-11-09T14:42:04 < DelvingDeeper> And then I wanted to use the shift register to increase the read speeds
2017-11-09T14:43:16 < dongs> whats the output rate on these
2017-11-09T14:43:21 < dongs> im too lazy to read shit i dont really care about
2017-11-09T14:43:34 < DelvingDeeper> anything from 4MHZ to 32
2017-11-09T14:43:49 < dongs> so you can still use SPI. does it output the sync clock for the data?
2017-11-09T14:43:52 < dongs> DCLK is output right?
2017-11-09T14:44:40 < DelvingDeeper> DCLK is always running and is the clk by which the data is shifted out
2017-11-09T14:44:57 < DelvingDeeper> DRDY pulses when new data is about to be shifted out
2017-11-09T14:48:25 < DelvingDeeper> So scrape everything and rather implement spi?
2017-11-09T14:50:57 < dongs> yeah
2017-11-09T14:50:58 < dongs> i would
2017-11-09T14:51:11 < dongs> how soon after drdy do you ened to read?
2017-11-09T14:51:18 < dongs> immediately?
2017-11-09T14:51:24 < DelvingDeeper> yep, immediately
2017-11-09T14:51:25 < dongs> maybe you can ghetto it up wiht some latches as SPI slave select
2017-11-09T14:51:31 < dongs> so it pulses but stays latched
2017-11-09T14:51:36 < dongs> then its all automatic
2017-11-09T14:51:51 < dongs> you setup 2 spi channels wiht DMA, same clock to both, serial input to both
2017-11-09T14:51:59 < Thorn> wtf https://developers.google.com/web/updates/2016/03/access-usb-devices-on-the-web
2017-11-09T14:51:59 < dongs> then fire it up and done
2017-11-09T14:52:07 < dongs> Thorn: mega old
2017-11-09T14:52:58 < Thorn> is it like html5 lilbusb?
2017-11-09T14:53:03 < dongs> yeah
2017-11-09T14:55:01 < DelvingDeeper> dongs: This sorts alot of my problems. thanks a lot.
2017-11-09T14:55:11 < DelvingDeeper> feelin stupid af rightnow
2017-11-09T14:55:36 < dongs> make sure you pick SPIs that can have separate DMA channels etc. with some plannig, but it should work
2017-11-09T14:55:46 < dongs> at least less insane than sampling gpio
2017-11-09T14:57:21 < dongs> anyway, your current shit should also work, i dont really see why its not
2017-11-09T14:57:29 < DelvingDeeper> This was all ok'd by my supervisors aswell >.< I'll have another chat with them
2017-11-09T14:57:30 < dongs> youre clocking DMA by DCLK
2017-11-09T14:57:37 < dongs> so it *should* work
2017-11-09T14:57:50 < dongs> all you really need to do is fire it up on a EXTI or something
2017-11-09T14:57:53 < dongs> why is tehre a timer involveD?
2017-11-09T14:58:11 < dongs> or even two timers, wiht master/wtc shit

2017-11-09T14:58:33 < dongs> maybe timer w/ETR to external reset, clock it from DCLK, and setup DMA
2017-11-09T14:59:52 < DelvingDeeper> I'm not using the timers at all.. The timer just sends a dma request when a rising edge is detected on its pin. The DMA then reads 8 or 16 bits to memory. I never use the timer handler or anything, So essentially I'm just telling the DMA take all the bits on the gpio and store them in memory

2017-11-09T15:02:46 < zyp> no excuse anymore :p
2017-11-09T15:03:12 < karlp> no excuse for what?
2017-11-09T15:04:25 < c10ud> "The advantages with this type of fast charger can be found in the multi-protocol design, which supports cloud-based technology."
2017-11-09T15:04:26 < c10ud> orly
2017-11-09T15:04:44 < zyp> wat
2017-11-09T15:04:47 < karlp> there, there's a shitty soap protocol for talking to charger posts about billing and charging details
2017-11-09T15:04:59 < zyp> yeah, OCCP or something
2017-11-09T15:05:02 < karlp> eyah, that one.
2017-11-09T15:05:14 < karlp> and because that's a server somewhere, that qualifies as "cloud!"
2017-11-09T15:05:52 < zyp> weird thing to focus on
2017-11-09T15:08:18 < zyp> the ABB chargers are good though
2017-11-09T15:09:07 < zyp> the norwegian chargepoint operators like mixing chargers at the locations, probably to give multi-vendor redundancy
2017-11-09T15:10:21 < karlp> I've only see private ones and these ON ones so far, and that's a local power company, and currently it's all been promo-free, no idea what the real plan is going to be.
2017-11-09T15:10:33 < karlp> oh, ikea has some different ones I guess.
2017-11-09T15:10:47 < karlp> they're going to need a lot more soonish, than just adding 15.
2017-11-09T15:10:52 < zyp> are you mixing fast chargers and slow chargers now?
2017-11-09T15:10:59 < karlp> probably.
2017-11-09T15:11:07 < zyp> sounded like it
2017-11-09T15:11:30 < karlp> but for what I presume is fast chargers, I've only seen one type, though I think ikea has different ones.
2017-11-09T15:11:40 < karlp> ikea at least has spaces for maybe 20 cars.
2017-11-09T15:11:44 < karlp> some other shops have like 1.
2017-11-09T15:11:48 < karlp> so they can say they're cool
2017-11-09T15:12:05 < karlp> but really it's just for tha car shared by staff or something
2017-11-09T15:12:28 < zyp> 20 cars in one spot? that'd be slow chargers
2017-11-09T15:12:41 < zyp> i.e. just feed AC to the internal charger in the car
2017-11-09T15:13:49 < karlp> doubt it, it's probably 6 posts, 4 cars each or something.
2017-11-09T15:14:05 < zyp> doubt what?

2017-11-09T15:14:38 < karlp> might buy a newtome car next year though
2017-11-09T15:14:51 < zyp> I mean, even in norway I haven't seen more than four fast chargers in one spot
2017-11-09T15:15:03 < karlp> more annoyed by the failing windscreen heater in my current car honestly.
2017-11-09T15:15:04 < zyp> (apart from tesla, but they don't count)
2017-11-09T15:15:14 < karlp> still works on half, but the passenger half.
2017-11-09T15:15:26 < karlp> not sure that's fixable without a windscreen replacement
2017-11-09T15:15:45 < zyp> windscreen heater? electric?
2017-11-09T15:15:48 < karlp> yeah
2017-11-09T15:16:04 < zyp> which car do you have?
2017-11-09T15:16:11 < karlp> fine zigzag pattern all over the windscreen you don't see until you look for it, but suppppper nice in winter :)
2017-11-09T15:16:21 < karlp> ford focus stationwagon, 2005.

2017-11-09T15:17:08 < karlp> had to stand outside and scrape ice this morning like a fucking pleb
2017-11-09T15:17:41 < karlp> bright side, I can just leave my frozen groceries in the car :)
2017-11-09T15:17:50 < zyp> electric windscreen heaters doesn't seem very common
2017-11-09T15:18:18 < zyp> I mean, my car has that, but the argument there is that it saves electricity since it's more efficient than heating air to blow at it
2017-11-09T15:20:41 < karlp> it's a massive night and day difference vs hot air
2017-11-09T15:21:00 < karlp> at least in any car I've drive, you've got to wait for the air to get hot first. and then it only starts in one area, and expands out
2017-11-09T15:21:14 < zyp> true
2017-11-09T15:21:45 < zyp> does it have some sort of timer or remote function so you can have your car ice free by the time you get into it?
2017-11-09T15:22:02 < karlp> I can get in, press "max heat now!" (it got a special button and everything) and it's deiced the windscreen enough to get clean in 20-30secs
2017-11-09T15:22:11 < karlp> hell no, it's a 12 year old focus,
2017-11-09T15:22:26 < karlp> I don't even have an aux in or usb for the radio.
2017-11-09T15:22:30 < zyp> haha
2017-11-09T15:22:42 < karlp> I have such modern features as side airbags
2017-11-09T15:22:54 < zyp> well, heater timers aren't all that new :p
2017-11-09T15:23:15 < zyp> pretty sure that existed in 2005
2017-11-09T15:23:26 < karlp> oh sure, but not on this.
2017-11-09T15:23:30 < zyp> but yeah, agreed on the convenience
2017-11-09T15:23:54 < karlp> it's in the manual iirc, there was an extended winter pack that you had to program timings into, sounded reallllly obtuse to actually set up
2017-11-09T15:23:59 < zyp> I think I forgot my ice scrape in my old car when I scrapped it and I haven't bothered getting a new one yet

2017-11-09T15:30:31 < zyp> I think it has been dethroned, but I haven't been following
2017-11-09T15:31:09 < zyp> that's 20 tesla chargers, four normal fast chargers (chademo/ccs) and four 22kW AC outlets
2017-11-09T15:32:11 < karlp> hrm, these look like regular slow chargers, but they're not the ones that they have now, they just haven't updaetd their website: https://www.ikea.is/hledsla
2017-11-09T15:32:49 < zyp> yeah, all of those are AC points
2017-11-09T15:33:24 < zyp> which is reasonable enough, AC points are way cheaper and good for a place you might spend a couple of hours shopping or whatever
2017-11-09T15:33:48 < zyp> on a DC fast charger, I typically need like 20 minutes

2017-11-09T19:16:21 < qyx> learing every day
2017-11-09T19:18:59 < c10ud> is there any open lis3dsh code doing calib wandering around?
2017-11-09T19:19:16 < qyx> ask Laurenceb
2017-11-09T19:19:17 < c10ud> just want to be ready when the evals arrive
2017-11-09T19:19:42 < qyx> he is usually doing some woodoo with mems sensors
2017-11-09T19:19:42 < c10ud> Laurenceb, hi ^
2017-11-09T19:19:52 < Laurenceb> <c10ud> lol I'm writing some atm
2017-11-09T19:20:19 < qyx> be prepared it will contain no spaces
2017-11-09T19:20:24 < c10ud> are you working with a dual config?
2017-11-09T19:20:46 < Laurenceb> current code needs a bit of fine tuning prob
2017-11-09T19:20:47 < Laurenceb> https://pastebin.com/M7dALTu2
2017-11-09T19:20:55 < Laurenceb> dual config? whats that?
2017-11-09T19:22:07 < c10ud> I want to use two lis3dsh with stm32f4 and get differential results from a moving thing
2017-11-09T19:22:14 < c10ud> that's why I need calibration
2017-11-09T19:22:25 < Laurenceb> ah
2017-11-09T19:22:48 < Laurenceb> 6 point cal should get you down to <0.1% sensitivity error
2017-11-09T19:23:02 < Laurenceb> they seem to differ by ~ +-0.5% from the factory
2017-11-09T19:24:18 < c10ud> well to be honest I think in my case it's not really the factory calibration but how they're mounted
2017-11-09T19:25:18 < c10ud> if I'm going to monitor variations between each other I just need to clear up which axis is what
2017-11-09T19:26:10 < c10ud> e.g. a variation on z may contain some angle bias on the other
2017-11-09T19:26:18 < Laurenceb> ah
2017-11-09T19:26:26 < Laurenceb> yeah thats not really what my code is about
2017-11-09T19:26:46 < c10ud> i see mag, gyro and accel, is this some sort of imu?
2017-11-09T19:28:13 < c10ud> I may have a question for you though, how are you getting data out from stm32? I'm dev'ing on disco
2017-11-09T19:28:23 < c10ud> if I can avoid hooking up a serial port, better
2017-11-09T19:28:56 < c10ud> printf with keil could be enough (i expect around 20kbps)
2017-11-09T19:30:32 < qyx> ^ semihosting
2017-11-09T19:31:01 < qyx> but it is not very fast, at least with openocd
2017-11-09T19:31:21 < upgrdman> regarding cpu instructions, whats the diff between "issue" and "dispatch"
2017-11-09T19:32:02 < Laurenceb> its a custom usb device
2017-11-09T19:32:13 < Laurenceb> yeah its an imu

2017-11-09T19:33:24 < c10ud> I'll try and see
2017-11-09T19:35:38 < englishman> Laurenceb: what do you think of theory of operation of MMC5883MA
2017-11-09T19:35:47 < englishman> However, the influence of a strong magnetic field
2017-11-09T19:35:47 < englishman> (more than 10 G) in any direction could upset, or flip,
2017-11-09T19:35:47 < englishman> the polarity of the film, thus changing the sensor
2017-11-09T19:35:47 < englishman> characteristics. A strong restoring magnetic field must
2017-11-09T19:35:47 < englishman> be applied momentarily to restore, or set, the sensor
2017-11-09T19:35:47 < englishman> characteristics. The MEMSIC magnetic sensor has an
2017-11-09T19:35:47 < englishman> on-chip magnetically coupled strap: a SET/RESET
2017-11-09T19:35:48 < englishman> strap pulsed with a high current, to provide the
2017-11-09T19:35:48 < englishman> restoring magnetic field.
2017-11-09T19:35:49 < englishman> liek wtf
2017-11-09T19:36:24 < Laurenceb> sounds like regular degaussing
2017-11-09T19:36:33 < englishman> yeah but why is this the only mag
2017-11-09T19:36:35 < Laurenceb> nothing weird
2017-11-09T19:36:49 < englishman> does lis3mdl do degaussing
2017-11-09T19:36:51 < Laurenceb> all magnos have set/reset or at least reset
2017-11-09T19:36:54 < Laurenceb> yes
2017-11-09T19:36:58 < englishman> o rly
2017-11-09T19:36:59 < Laurenceb> but badly
2017-11-09T19:37:10 < englishman> yeah because this requires 10uf external cap to get enough current
2017-11-09T19:37:14 < Laurenceb> so it has a temperature dependent offset
2017-11-09T19:37:30 < Laurenceb> I might do a new pcb with lis2 instead
2017-11-09T19:37:34 < Laurenceb> as its more stable

2017-11-09T21:39:55 < jpa-> permission denied sounds like it is not using virtualenv

2017-11-09T22:49:43 < jadew> the tank size on that 3L cleaner would fit my board, but I don't think it would fit in the basket
2017-11-09T22:50:21 < jadew> they should give the basket size instead
2017-11-09T22:51:22 < Steffanx> If the basket is like an inch smaller than the tank, it should fit right?
2017-11-09T22:51:25 < Steffanx> 16x10
2017-11-09T22:51:50 < jadew> yeah, tightly

2017-11-09T23:02:16 < jadew> you're not getting much rain in there?
2017-11-09T23:02:20 < zyp> because all it does is drag shit across the window when I turn it on by accident

2017-11-09T23:03:35 < zyp> idk, I don't find it very useful
2017-11-09T23:04:21 < zyp> I can tell whether there's a car behind me or not even if it's dirty
2017-11-09T23:04:49 < zyp> and IMO it looks nicer with an even layer of shit across the window than a smear in the middle :p
2017-11-09T23:05:32 < Steffanx> You can clean it with rear window sprayer right?
2017-11-09T23:05:55 < zyp> sure, still looks like shit
2017-11-09T23:06:22 < jadew> I prefer the sedan cars, the window never gets dirty
2017-11-09T23:06:31 < jadew> *rear window
2017-11-09T23:06:56 < Steffanx> but i can imagine the roads in norway are a bit muddier. Dont you guys use sand when it's snowy/icy on the road?
2017-11-09T23:07:10 < zyp> yeah
2017-11-09T23:07:13 < zyp> sand and/or salt
2017-11-09T23:07:54 < zyp> worst conditions to drive in are after snow has melted, dirty wet roads
2017-11-09T23:07:59 < BrainDamage> here people just use bottles of warm water to defrost the windshield in the morning
2017-11-09T23:08:45 < zyp> take a long trip in conditions like that and you'll go through a can of windshield fluid in a day
2017-11-09T23:08:46 < Steffanx> Nothing wakes me better than getting rid of the ice on the windows of my car by hand.

2017-11-09T23:11:15 < zyp> I like how it has like 25cm of snow on the rear window and nothing on the roof
2017-11-09T23:11:17 < Steffanx> As in: does the glass never ever crack.
2017-11-09T23:11:43 < BrainDamage> no idea, I've never done with mine since i have a covered parking spot
2017-11-09T23:12:02 < Steffanx> nah zyp. I wouldnt visit norway in the winter.
2017-11-09T23:12:08 < zyp> aww
2017-11-09T23:12:16 < BrainDamage> but i imagine not particularry, you'd first have to raise the ice/water slush temperature
2017-11-09T23:12:17 < jadew> seems I have it the worst, my car is usually half under snow
2017-11-09T23:12:22 < BrainDamage> then the glass below
2017-11-09T23:12:40 < jadew> and I have to get up really early to dig it out, so my wife can get to work
2017-11-09T23:13:21 < jadew> and each night when they clear the road, they throw that snow on our car
2017-11-09T23:13:32 < Steffanx> hah
2017-11-09T23:13:37 < jadew> by morning all that show is frozen and forming a fence around the car
2017-11-09T23:13:51 < jadew> that's always a pleasure to deal with

2017-11-09T23:31:06 < zyp> there's more wind than snow there, so it blows around and piles up here and there instead of falling evenly

2017-11-09T23:41:46 < karlp> yes, but there's still a limit
2017-11-09T23:41:52 < karlp> trains for a city of 180k?
2017-11-09T23:42:15 < karlp> we have busses, they work ok I'm told.
2017-11-09T23:42:23 < BrainDamage> 180k is a bit small for trains, you could get trams and busses
2017-11-09T23:42:31 < BrainDamage> busses can be wire supplied
2017-11-09T23:42:58 < karlp> yeah, we're not putting in overhead wires for that
2017-11-09T23:43:06 < karlp> you think this is italy or sanfran or some shit?
2017-11-09T23:43:38 < BrainDamage> they can be rail supplied too for trams
2017-11-09T23:44:13 < englishman> dont listen to him, braind is in shorts and a wifebeater on the beach right now
2017-11-09T23:44:16 < englishman> he knows not of what he speaks
2017-11-09T23:44:36 < BrainDamage> it rained 200mm in 2 days
2017-11-09T23:44:43 < karlp> like we're going to lay rails either :)
2017-11-09T23:44:57 < karlp> we have soft mushy roads for our studs to rip into, so we can keep replacing them.
2017-11-09T23:48:08 < zyp> karlp, one of my friends joked about taking their EV on a ferry to .is to go try your new fast chargers
2017-11-09T23:48:15 < zyp> could have been a fun trip
2017-11-09T23:48:34 < qyx> so only roads in the .is?
2017-11-09T23:49:31 < qyx> we have these here https://en.wikipedia.org/wiki/%C5%A0koda_30_T
2017-11-09T23:49:35 < qyx> 600kW \o/
2017-11-09T23:50:18 < qyx> sk
2017-11-09T23:50:53 < karlp> getting around the country in an ev is at l east feasible now, but it requires planning.
2017-11-09T23:50:58 < karlp> totally fine in town.
2017-11-09T23:51:07 < karlp> but yeah, come on over :)
2017-11-09T23:51:51 < karlp> slovak?
2017-11-09T23:51:57 < karlp> what else would they speak?
2017-11-09T23:52:13 < karlp> oh, sorry
2017-11-09T23:55:10 < qyx> superbia: this is czech
2017-11-09T23:56:01 < qyx> the guy is raging when repairing the car
2017-11-09T23:56:09 < qyx> that agricultural tractor or how is it called
2017-11-09T23:57:09 < zyp> karlp, hmm, ferry takes three days, that's not too bad for the distance
2017-11-09T23:57:24 < zyp> but still, that'll be almost a week just getting there and back :)
2017-11-09T23:58:45 < karlp> yeah, you only come by ferry if you _want_ to bring your car for something,
2017-11-09T23:58:56 < karlp> it's normally jeeps and rvs and shit.
2017-11-09T23:59:00 < zyp> hehe
2017-11-09T23:59:06 < karlp> it's meant to be _terrribly_ boring.
2017-11-09T23:59:24 < karlp> a friend went a few years ago, said if he had to do it again, he'd pay for a friend to come so they could at least drink together.
--- Day changed Fri Nov 10 2017
2017-11-10T00:02:04 < zyp> https://en.wikipedia.org/wiki/Hurtigruten <- I took my car on this in february this year to shave off about 1000km of my drive south
2017-11-10T00:02:50 < zyp> took two days, expected it to be boring as fuck
2017-11-10T00:03:19 < zyp> somehow ended up enjoying it, despite travelling alone
2017-11-10T00:04:52 < karlp> that's coastal though right, yuou get to see shit
2017-11-10T00:04:55 < karlp> and people get on an doff.
2017-11-10T00:05:13 < karlp> the ferry to iceland is just seasick people on the north atlantic, and a few hours in torshafn
2017-11-10T00:05:14 < zyp> yeah, and there's plenty of time to disembark here and there
2017-11-10T00:06:01 < zyp> didn't want to pay for onboard food, so went to a couple of restaurants close to the ports instead
2017-11-10T00:07:20 < zyp> onboard sauna and outdoor jaucuzzis were free, so I spent some hours in those
2017-11-10T00:07:27 < zyp> and some hours reading books
2017-11-10T00:07:46 < zyp> oh, and coastal means you actually get working cellular most of the time
2017-11-10T00:13:45 < englishman> zyp, icelandair is great
2017-11-10T00:14:00 < englishman> you can come to america, stop in reykjavik and stay as long as you want
2017-11-10T00:14:10 < zyp> hehe
2017-11-10T00:18:40 < upgrdman> but isn't it cold
2017-11-10T00:19:00 < upgrdman> so cal masterrace checking in. t-shirts in the winter FTW
2017-11-10T00:21:35 < karlp> englishman: ya man, come on by whenever you want :)
2017-11-10T00:21:44 < englishman> same goes for you bro
2017-11-10T00:22:04 * karlp feels warm.
2017-11-10T00:24:18 < zyp> karlp, how about skipping køben and coming here instead? I'll buy you a beer
2017-11-10T00:25:16 < karlp> nah, köben is a work trip :)
2017-11-10T00:25:24 < karlp> like I'd go there for fun
2017-11-10T00:25:39 < zyp> haha
2017-11-10T00:33:26 < zyp> karlp, oh, btw, now I'm through the two first expanse books and have started on the third
2017-11-10T00:33:37 < zyp> is the series as good as the books? is it worth watching?
2017-11-10T00:35:04 < zyp> the books are totally worth reading at least
2017-11-10T00:36:03 < Steffanx> Do you read analogue
2017-11-10T00:36:05 < Steffanx> ?
2017-11-10T00:37:06 < Steffanx> да
2017-11-10T00:37:43 < zyp> Steffanx, read what?
2017-11-10T00:38:05 < Steffanx> The books you read.
2017-11-10T00:38:41 < zyp> you mean paper books?
2017-11-10T00:38:53 < Steffanx> Yes zyp
2017-11-10T00:39:03 < zyp> no, I read on kindle
2017-11-10T00:40:42 < zyp> I used to, when I were a kid
2017-11-10T00:41:02 < zyp> and then I stopped reading at some point
2017-11-10T00:42:05 < zyp> until I bought a kindle, and then the convenience made me start reading again
2017-11-10T00:42:49 < Steffanx> Anyway, imho the series are so-so. Never read the books, so cant compare
2017-11-10T00:44:48 < englishman> can someone tell me what the difference is between Wurth 36103205 and 36103205S
2017-11-10T00:45:11 < englishman> also 36003200 and 36003200S
2017-11-10T00:45:37 < zyp> S
2017-11-10T00:45:47 < englishman> on cars, S means they charge more money
2017-11-10T00:45:54 < englishman> with wurth, it's half price
2017-11-10T00:46:35 < karlp> any awk people?
2017-11-10T00:47:01 < karlp> ideas why "$ echo "1234" | gawk '{printf("%x\n", $1)}'" works for decimal to hex, but echo "0x1234" and using %d instead of %x just always returns 0
2017-11-10T00:47:53 < karlp> https://www.youtube.com/watch?v=w05M20O7fmE&feature=youtu.be&t=1332
2017-11-10T00:48:07 < karlp> zyp: I thought the tv series was _reallly_ good,
2017-11-10T00:48:16 < englishman> looks like one is certified, the other is uncertified but otherwise identical
2017-11-10T00:49:58 < Steffanx> karlp: i only remember i had a hard time getting through the first 2 episodes
2017-11-10T00:49:59 < englishman> i feel the same way zyp, i collected books but never read them until i got an ereader
2017-11-10T00:50:02 < jadew> which tv series?
2017-11-10T00:50:07 < karlp> the expanse
2017-11-10T00:50:21 < jadew> ah, I think I'm at episode 2
2017-11-10T00:50:31 < jadew> I should start it over
2017-11-10T00:51:23 < karlp> frack, that awk works on the awk that will matter, but not on my desktop awk.
2017-11-10T00:52:19 < zyp> the books are the sort that's a bit heavy to start on because they dump a lot of characters and other setup without a lot of context to fit it together
2017-11-10T00:52:37 < karlp> tv does too,
2017-11-10T00:52:38 < zyp> but it makes a lot more sense once you get some chapters in
2017-11-10T00:52:39 < karlp> language and all sorts

2017-11-10T00:56:08 < zyp> also looking forward to see this whenever it's out: http://www.imdb.com/title/tt2261227/
2017-11-10T00:56:12 < zyp> the books were good

2017-11-10T01:04:53 < Laurenceb_> banter boy
2017-11-10T01:13:22 < Laurenceb_> Englishman: do you have the MMC magno running on anyboards?
2017-11-10T01:13:32 < englishman> no, hasnt arrived yet
2017-11-10T01:13:42 < englishman> chipz and pcbs will be here end of next week or so
2017-11-10T01:14:17 < Laurenceb_> ah ok
2017-11-10T01:14:25 < Laurenceb_> it looks better than any of the ST stuff
2017-11-10T01:14:29 < englishman> yep
2017-11-10T01:14:36 < Laurenceb_> about 10% more stable and 6 times lower noise
2017-11-10T01:14:38 < englishman> easier to solder too
2017-11-10T01:14:40 < Laurenceb_> also 600hz update
2017-11-10T01:14:54 < Laurenceb_> I'm just worried about emi
2017-11-10T01:15:01 < englishman> as you should be
2017-11-10T01:15:01 < Laurenceb_> the HMC5883 was really bad
2017-11-10T01:15:28 < Laurenceb_> totally trashed any sensitive analogue stuff nearby
2017-11-10T01:15:38 < englishman> o you mean emitted
2017-11-10T01:15:40 < englishman> interesting
2017-11-10T01:15:49 < Laurenceb_> yeah, the set/reset thing
2017-11-10T01:15:54 < englishman> ahh
2017-11-10T01:16:04 < englishman> could you set this on hmc5883?
2017-11-10T01:16:39 < Laurenceb_> *see ?
2017-11-10T01:16:48 < zyp> Laurenceb_, considering how shitty your ground planes are, there's no wonder your analog stuff gets trashed
2017-11-10T01:16:54 < zyp> or have you gotten better at that?
2017-11-10T01:17:00 < Laurenceb_> on my autopilot board the pitot sensor was useless when hmc was running
2017-11-10T01:17:07 < Laurenceb_> zyp: its not ground currents
2017-11-10T01:17:13 < Laurenceb_> its inductive coupling
2017-11-10T01:17:39 < Laurenceb_> set/reset is a coil around the sensor
2017-11-10T01:17:48 < zyp> well, duh, proper ground planes reduce the inductance of the signal traces
2017-11-10T01:18:21 < Laurenceb_> reduce but dont eliminate
2017-11-10T01:18:21 < englishman> it says max field before degaussing is 10G
2017-11-10T01:18:24 < englishman> isnt that a lot
2017-11-10T01:18:56 < zyp> of course, there's no such thing as eliminating in analog
2017-11-10T01:19:03 < Laurenceb_> englishman: yes
2017-11-10T01:19:18 < englishman> like, proximity to a real magnet lot
2017-11-10T01:19:21 < zyp> you can only reduce noise until it's below whatever threshold you deem acceptable
2017-11-10T01:19:27 < Laurenceb_> zyp: my pitot sensor stuck up off the pcb, probably made it more vulnerable
2017-11-10T01:19:58 < Laurenceb_> other sensors and stm32 adc were fine
2017-11-10T01:20:33 < Laurenceb_> you can easily pick up HMC pulses with an inductive probe and a scope
2017-11-10T01:21:08 < Laurenceb_> englishman: I got LIS3 cal working properly in my lab
2017-11-10T01:21:24 < Laurenceb_> turns out matlab fminsearch is crap
2017-11-10T01:21:41 < Laurenceb_> so I rewrote using modified Newton-Raphson
2017-11-10T01:22:10 < Laurenceb_> LIS3 offset is so high the x axis is always >0 O_o
2017-11-10T01:22:12 < englishman> Laurenceb_ it looks like degaussing is only ever done manually, so you can at least account for this effect in other readings
2017-11-10T01:22:43 < Laurenceb_> ah cool
2017-11-10T01:23:46 < Laurenceb_> my lab is interesting - steel framed building
2017-11-10T01:24:15 < Laurenceb_> earth field is only about 25µT, rather than 50µT or so, but the angle is off by less than 5 degrees

2017-11-10T03:39:49 < emeb_mac> got a cheapo $8 uBlox GPS board from a random ebay seller. Works fine.
2017-11-10T03:39:53 < Laurenceb_> nice
2017-11-10T03:40:14 < Laurenceb_> stm32f042 i2c1 dma channels are the same as spi1
2017-11-10T03:40:16 < Laurenceb_> rage
2017-11-10T03:40:31 < emeb_mac> ugh
2017-11-10T03:40:50 < Laurenceb_> its as bad as F1
2017-11-10T03:41:14 < Laurenceb_> I wonder if cubemx interrupt i2c driver is any good
2017-11-10T03:41:24 < Laurenceb_> or maybe I could use my f1 i2c driver
2017-11-10T03:41:45 < emeb_mac> haven't tried the cubemx irq driver. PIO driver works fine
2017-11-10T03:42:14 < emeb_mac> haven't ever had an application for I2C that needed enough bandwidth to warrant DMA
2017-11-10T03:42:40 < emeb_mac> esp since ST's DMA needs so much handholding
2017-11-10T03:42:44 < Laurenceb_> yeah I'd only use it as the cubemx i2c dma code looks usable
2017-11-10T03:42:58 < emeb_mac> err not DMA but I2C - it needs a lot of CPU intervention.
2017-11-10T03:43:23 < emeb_mac> not exactly fire & forget like SPI
2017-11-10T03:44:11 < Laurenceb_> yeah
2017-11-10T03:44:44 < Laurenceb_> I'm thinking of making a new imu board with mmc magno

2017-11-10T03:45:13 < emeb_mac> fun
2017-11-10T03:45:33 < emeb_mac> betcha IRQ-based I2C would probably be fine
2017-11-10T03:47:18 < Laurenceb_> yeah F1 i2c was particularly bad

2017-11-10T05:25:32 < ingrix> I am attempting to get the USB interface of an STM32F103 Blue Pill board working. Does anyone have any idea of why it's detected as a low-speed device instead of a full-speed device as per specs?
2017-11-10T05:27:39 < ingrix> this board has an incorrect 10K pullup resistor on the D+ line, so I spliced in a 1.8K resistor to make up for that
2017-11-10T05:28:16 < dongs> do you have 1.5k?
2017-11-10T05:28:18 < ingrix> now the D+ line reads at 2.6V when connected to a hub, which I believe should be adequate to signal a full-speed device
2017-11-10T05:28:20 < dongs> i dont know how accurate that needs to be
2017-11-10T05:28:34 < dongs> 1.5k 1% is the spec
2017-11-10T05:29:10 < dongs> oh, you added 1.8 in parallel
2017-11-10T05:29:13 < ingrix> well, with the 10K that's in there right now, the 1.8K in parallel should bring the equivalent resistance down to 1.5K
2017-11-10T05:29:14 < dongs> to make 1.52k or so
2017-11-10T05:29:15 < dongs> yeah
2017-11-10T05:29:31 < dongs> i thought by "spliced" you meant like put in series or replaced or soemthign
2017-11-10T05:29:39 < ingrix> oh, no, sorry
2017-11-10T05:29:54 < dongs> anyawy, yeah should work
2017-11-10T05:30:12 < dongs> have you tried using ST's simple hid or dfu demos
2017-11-10T05:30:16 < ingrix> hmmm. interesting. I've tried a few different values with the same effect
2017-11-10T05:30:17 < dongs> to make sure its not your code
2017-11-10T05:30:27 < dongs> using stdperiph right
2017-11-10T05:30:31 < ingrix> not those particular ones, but I've tried using some examples from libopencm3
2017-11-10T05:30:38 < dongs> or that.
2017-11-10T05:31:20 < dongs> https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Flashing-Bootloader-for-BluePill-Boards
2017-11-10T05:31:26 < dongs> this has some crap, im sure youve seen it right
2017-11-10T05:32:16 < ingrix> that particular one is new, but it looks like it covers the same general stuff as the other pages I saw
2017-11-10T05:32:25 < ingrix> I'll take a look to see if there's anything different
2017-11-10T05:32:47 < dongs> ya from a quick look it just seems same thing ,wrong value and what the real circuit should haev been
2017-11-10T05:34:53 < dongs> http://firtel.blogspot.jp/2017/03/blue-pill-stm32duino.html this jap says all he did was change resistor.
2017-11-10T05:35:12 < dongs> so it should just work
2017-11-10T05:35:26 < ingrix> haha yeah, if only it would :D
2017-11-10T05:42:28 < Thorn> what is the point of injected adc channels
2017-11-10T06:01:17 < ingrix> dongs: it looks like it was a hardware issue. I changed cables and it seems to be enumerating using the maple bootloader now. thanks for your help

2017-11-10T11:01:30 < PaulFertser> I'm observing windows "evolution" since win 3.1; still amazes me by all the different shit that happens to their users. It's like almost 30 years of "dominating" the market and they still are unable to provide anything solid, something that wouldn't behave creepy as hell in all the "edge" cases.
2017-11-10T11:01:46 < dongs> yeah? well guess what
2017-11-10T11:03:08 < dongs> i'm observing lunix users since ~1990; still amazes me how they don't have a working browser, word processor, or an office suite. how hardware only gets support when it becomes EOL from manufacturer. how almost nothing new is guarnateed to work and/or will need constant fucking around with. how there's not a single stable system where developers cooperate instead every faggot just makes their own shit, resulting in over 9000 useless buggy distros.

2017-11-10T12:36:53 < dongs> zyp, eyah
2017-11-10T12:36:57 < dongs> their discas online shit.
2017-11-10T12:37:27 < zyp> haha
2017-11-10T12:37:34 < zyp> copying rentals sounds legal as fuck
2017-11-10T12:38:08 < daey> you can just copy the stream, and dont have to deal with shipping around discs lol
2017-11-10T12:38:21 < zyp> but, but, muh bitrate!

2017-11-10T13:46:38 < qyx> anyone tried connecting a cf card to stm32?
2017-11-10T13:48:56 < jpa-> qyx: FSMC claims to have compact flash support
2017-11-10T13:50:05 < qyx> I know, but I don't believe until I see
2017-11-10T13:57:53 < jadew> anyone using a < 1k CNC?
2017-11-10T13:58:17 < jadew> I'm in the market for one and not really sure what I should be looking for
2017-11-10T13:59:26 < qyx> wut 2mil cycles for an industrial SLC CF card
2017-11-10T14:17:12 < jpa-> jadew: i have cnc3020, it works (though i did replace the original controller with a smoothieboard)
2017-11-10T14:17:35 < jadew> jpa-, did you mill any aluminium with it?
2017-11-10T14:17:55 < jpa-> yeah, and even steel, but it's not very good for it and it takes long
2017-11-10T14:18:09 < jadew> that's fine, as long as it can do it
2017-11-10T14:18:23 < jadew> what spindle power should I get?
2017-11-10T14:18:32 < jadew> I noticed there are multiple ones available
2017-11-10T14:18:43 < jpa-> http://essentialscrap.com/3dprinter/hotend.html e.g. there are few pieces of aluminum that i've cut with it
2017-11-10T14:19:03 < jpa-> hmm, can you link? there was only one when i bought mine, and it is the crappiest spindle in existence
2017-11-10T14:19:17 < jadew> they look really nice
2017-11-10T14:19:21 < jadew> yeah, give me a sec
2017-11-10T14:20:10 < Steffanx> Some replaced it with the dewalt 611
2017-11-10T14:20:43 < jadew> https://www.ebay.co.uk/itm/300-400-560-800-1500W-CNC-Router-Engraver-Milling-Engraving-Cutter3020-3040-6040-/282550238144
2017-11-10T14:20:46 < Steffanx> (have been looking into the 3020/3040 a bit last week )
2017-11-10T14:21:16 < jadew> Steffanx, what did you think? they don't look bad, isn't it?
2017-11-10T14:21:16 < jpa-> we bought makita rt0701c for hacklab's bigger cnc.. but that thing is *loud* compared to cnc3020's spindle
2017-11-10T14:21:40 < jadew> considering the other options are way more expensive and the frame is made out of wood/plastic in some cases
2017-11-10T14:22:36 < jadew> Steffanx, I saw one with a bosh spindle
2017-11-10T14:22:43 < jadew> (custom, not for sale)
2017-11-10T14:22:44 < jpa-> yeah, my spindle is that "300W" one there, all the others look better
2017-11-10T14:23:01 < jadew> that's the model you have? the one I linked to?
2017-11-10T14:23:07 < jpa-> that seems to be the only option available for 3020 though
2017-11-10T14:23:12 < jadew> cuz there are different ones available too, with different frames
2017-11-10T14:23:16 < Steffanx> From what i see jpa- they domt look too bad jadew
2017-11-10T14:23:26 < Steffanx> But i would go for 3040 i think
2017-11-10T14:23:37 < Steffanx> larger is better (tm)
2017-11-10T14:23:47 < jpa-> jadew: looks like same as the "parallel port 3 axis CNC 3020"
2017-11-10T14:24:48 < jpa-> but i'd recommend going for one of the 800W models, look like they have watercooled spindle which should be more quiet also
2017-11-10T14:24:58 < jadew> there's also this type available? https://www.ebay.co.uk/itm/Top-CNC-3-AXIS-ENGRAVER-USB-CNC-3020-ROUTER-ENGRAVING-DRILLING-MILLING-MACHINE/282488852660
2017-11-10T14:25:02 < jadew> it's the same thing?
2017-11-10T14:25:22 < jpa-> close, that looks like to have the usb controller but the same crappy spindle
2017-11-10T14:25:43 < jpa-> the spindle is the most limiting factor on my CNC3020 so i'd recommend getting one of the better ones
2017-11-10T14:25:47 < Steffanx> You always browse the co.uk website? jadew
2017-11-10T14:25:52 < karlp> invzim is in .no too?
2017-11-10T14:25:54 < jadew> Steffanx, yeah, why?
2017-11-10T14:26:02 < karlp> we're really starting to have anoticeable lake of danes
2017-11-10T14:26:11 < Steffanx> I like you seem to not see the chinese sellers
2017-11-10T14:26:11 < jadew> it gives results more relevant to the EU
2017-11-10T14:26:20 < Steffanx> In my quest it was chinanonly
2017-11-10T14:26:38 < Steffanx> So huge import taxes
2017-11-10T14:26:38 < jadew> yeah, they're at the end usually
2017-11-10T14:27:11 < jadew> jpa-, thanks for the info
2017-11-10T14:28:26 < jadew> I wonder which type is sturdier
2017-11-10T14:28:36 < jadew> the yellow one or the gray one
2017-11-10T14:29:31 < jadew> the yellow one has that little sheet metal fence
2017-11-10T14:29:32 < jpa-> the shape of the frame will not matter much, the length of the linear bearings is probably the same and that is the weakest point
2017-11-10T14:34:04 < jadew> I guess the 3020 would be sturdier, no?
2017-11-10T14:35:14 < jpa-> than what?
2017-11-10T14:35:20 < jadew> than the 3040
2017-11-10T14:36:24 < jpa-> dunno, why do you think that?
2017-11-10T14:36:44 < jadew> the shafts are longer
2017-11-10T14:36:50 < jadew> on the 3040
2017-11-10T14:37:31 < jpa-> the shafts are sturdy enough i think, for me the flex comes mainly from the linear bearings
2017-11-10T14:37:36 < jadew> I've seen a review that was complaining that for some CNCs they bend, so that reduces the vertical speed you can mill with
2017-11-10T14:37:55 < jadew> I see
2017-11-10T14:38:02 < jadew> could they be replaced?
2017-11-10T14:38:26 < jpa-> sure, but can't see a situation when you would break them
2017-11-10T14:38:42 < jadew> no, I mean to replace them with better ones
2017-11-10T14:38:51 < qyx> Laurenceb: did you find a LiIon/LiFePO4 with a datasheet claimed -20C charge temp when you did a research in the past?
2017-11-10T14:39:32 < jpa-> replace shafts or replace linear bearings? though probably you could replace either, but i haven't looked much into it
2017-11-10T14:39:44 < Laurenceb> qyx: I don't think I found any that were orderable
2017-11-10T14:39:57 < Laurenceb> LeoBodnar got some custom made from a factory in china
2017-11-10T14:40:05 < jadew> jpa-, the bearings, since you said they're the weak link
2017-11-10T14:40:06 < Laurenceb> and they actually worked well down to -55C
2017-11-10T14:40:18 < jadew> but yeah, considering the parts you were able to mill with it, I wouldn't replace them either
2017-11-10T14:40:32 < Laurenceb> apparently there are some tweaks to the electrode design and different additives
2017-11-10T14:40:34 < jpa-> yeah, it is relatively well balanced machine
2017-11-10T14:40:48 < Laurenceb> the factory were just able to tweak stuff and do a custom run of cells
2017-11-10T14:40:52 < qyx> Laurenceb: I found only those http://www.batteryspace.com/lithium-ion-rechargeable-cell-swing-5300-3-65v-5300-mah-19-3wh---un38-3-passed.aspx
2017-11-10T14:40:53 < jpa-> as soon as you replace one part with a better one, some other limits you
2017-11-10T14:41:29 < Laurenceb> qyx: looks believable to me
2017-11-10T14:41:36 < Laurenceb> but depends how much you trust them
2017-11-10T14:41:43 < jpa-> a lot of CNC info on the web is about a lot sturdier milling machines, these cheap CNC routers do not really compare and stuff like bending a solid 16 mm steel shaft just doesn't happen to any meaningful extent
2017-11-10T14:41:52 < Laurenceb> Leo wasn't convinced but he is crazy so tried ordering anyway
2017-11-10T14:42:02 < Laurenceb> and the cells actually met the claimed spec
2017-11-10T14:42:42 < jadew> jpa-, that's good
2017-11-10T14:42:52 < qyx> Laurenceb: A123 lifepo4 claims -30C too but they do not differentiate between charge/discharge for some reason
2017-11-10T14:43:05 < Laurenceb> well the chemistry is different
2017-11-10T14:43:09 < jadew> initially I only want to use it for drilling, but I'm sure I'll end up milling custom parts too
2017-11-10T14:43:26 < jpa-> but yeah, the linear bearings are of standard size and you could probably replace them with better ones for a slight improvement
2017-11-10T14:43:35 < Laurenceb> qyx: it seems -55C discharge ~-25C charge lipo can be easily built
2017-11-10T14:43:45 < Laurenceb> but nobody makes them off the shelf
2017-11-10T14:43:51 < Laurenceb> maybe there is little market
2017-11-10T14:44:17 < qyx> I am searching for some cots cells atm
2017-11-10T14:44:32 < Laurenceb> aiui when Leo spoke to the factory inh china they said it was no big deal and they had the right additives in stock and config loaded on the assembly tools
2017-11-10T14:44:52 < Laurenceb> but he couldn't find them off the shelf anywhere, had to order a whole production run
2017-11-10T14:45:08 < qyx> how much cells?
2017-11-10T14:45:33 < Laurenceb> I dont know, prob hundreds

2017-11-10T16:37:58 < jadew> those CNCs from china, they don't do variable speed, isn't it?
2017-11-10T16:38:56 < jadew> I wonder if there's some sort of adapter so they can be used for tapping as well

2017-11-10T16:52:57 < karlp> jadew: with a setscrew to hold the bit in place? looks attrocious
2017-11-10T16:53:28 < karlp> looks like the garbage hole saw drill set I bought
2017-11-10T16:57:44 < jadew> karlp, yeah, I don't want that particular one, I was just wonder if they're available
2017-11-10T16:58:21 < jadew> I'm trying to figure out how to drill 16 holes, tap 8 of them, with 4 on one side, 4 on the other side in the least amount of time
2017-11-10T16:59:28 < jadew> the tapping part is probably going to be the most problematic
2017-11-10T16:59:30 < karlp> I'd _assume all of one side at a time, tool changes should be far shorter than flipping the workpiece, and require far less precision in alignment
2017-11-10T17:00:12 < jadew> they're split across several pieces, but on one, I have 4 on one side, 4 on the other
2017-11-10T17:00:22 < jadew> and those are the ones that need tapping
2017-11-10T17:01:22 < jadew> I think the drilling part will be fairly easy, I just make a stopper for the vice where I'll mount the piece
2017-11-10T17:01:35 < jadew> so just press it against that stopper and then tighten it
2017-11-10T17:01:48 < jadew> hit enter, let the CNC make the holes
2017-11-10T17:01:52 < jadew> flip & repeat
2017-11-10T17:05:23 < jadew> if I could make maybe 20 boxes per hour, that would be fairly efficient
2017-11-10T17:06:38 < jadew> don't think I can tho, too many steps

2017-11-10T18:41:28 < karlp> not a lot of rifle game, the reindeer is a quite limited lotto
2017-11-10T18:41:46 < englishman> yeah, this was probably the last year reindeer even have a hunt, here
2017-11-10T18:41:49 < englishman> just too few
2017-11-10T18:41:57 < karlp> geese and ptarmigan and guillemot/cormorant are all shotgun

2017-11-10T18:42:57 < karlp> ends up here that _lots_ of people will have a shotgun, and go for a single, maybe two, social weekends a year in autumn, and that's that.
2017-11-10T18:43:42 < karlp> cops are very much trying to get lots more guns, "bcause terrrrrrror" and shit, but so far that's being fought back.
2017-11-10T18:43:54 < englishman> atm normalcops dont have guns, right
2017-11-10T18:44:19 < karlp> no, they have handguns in their car normally,
2017-11-10T18:44:35 < karlp> they're using the "viking squad" basically _all the time_ though now, and those guys do,

2017-11-10T18:47:51 < karlp> there were one or two people who were _close_ to qualifying for some shooting event iirc,

2017-11-10T22:08:37 < upgrdman> a cheap walmart china trash pillow is nicer

2017-11-10T22:14:52 < upgrdman> i have not really followed him. is he easily upset?
2017-11-10T22:14:58 < Steffanx> i think so
2017-11-10T22:15:14 < upgrdman> i guess i could have been gently, but the cum pillow remark was a light-hearted joke
2017-11-10T22:15:20 < upgrdman> gentler*
2017-11-10T22:15:21 < Steffanx> or just done with it, i can understand that.

2017-11-10T22:28:52 < upgrdman> didnt know about chinanet/cn2. that could explain why one hotel i was at was super slow on VPN and the other was almost acceptable on VPN
2017-11-10T22:28:58 < dekar_> upgrdman, let me know how it works for you.
2017-11-10T22:29:01 < upgrdman> will do
2017-11-10T22:29:44 < upgrdman> im guessing my workplace has cn2. because i can get >25Mbps to the USA around 75% of the time when im at work
2017-11-10T22:30:05 < upgrdman> but at one hotel its worse than dialup. and at another hotel i get >10Mbps to the USA around 50% of the time.
2017-11-10T22:30:25 < upgrdman> both hotels have lots of foreigners, so its not like one would have less international net usage
2017-11-10T22:31:20 < upgrdman> syncthing made my last cn trip livable. i would youtube-dl lots of shit to my Droplet in the USA, and let it sync ~50GB over night
2017-11-10T22:35:01 < dekar_> verzweiflung usually allows for youtube at 1080p, or so I have heard... *cough*
2017-11-10T22:35:10 < upgrdman> :D
2017-11-10T22:36:22 < upgrdman> lets hope cn's machine learning firewalls dont wise up to your tricks.

2017-11-11T00:06:24 < ohsix> i was losing the battle on advising the owner of the printer to get an enclosure and shit, but the fire gives me a decent break
2017-11-11T00:06:58 < upgrdman> ohsix, filament get too hot?
2017-11-11T00:07:32 < ohsix> nah heater bed thermistor got disconnected
2017-11-11T00:08:49 < upgrdman> oh, good design. disconnected thermal sensor is not interpreted as a fault. lol.
2017-11-11T00:09:00 < ohsix> it is, but it wasn't disconnected well enough
2017-11-11T00:09:31 < ohsix> partial failure leads to temp rise on the wires to the heating bed, the pins in the connector weren't as good as the wires
2017-11-11T00:09:57 < ohsix> connector got hotter than wire, it progressed; y moves around on this printer so the heater/thermistor wire does too
2017-11-11T00:10:47 < ohsix> there's a lot that's bad about this printer, it's not unique in that respect; but every time i talk about something with the owner he's like 'IT WAS RATED THE BEST IN MAKE MAGAZINE'
2017-11-11T00:10:56 < Steffanx> Better get your own resistor trimmer englishman
2017-11-11T00:11:10 < ohsix> that characterizes my frustration p. good

2017-11-11T00:15:05 < daey> is it possible to return a value of a variable before assigning a new value to it? something like 'return x && x=0;

2017-11-11T00:15:27 < daey> nice
2017-11-11T00:15:35 < vampi-the-frog> but it returns after assigning
2017-11-11T00:15:51 < daey> yeah thats not what i want
2017-11-11T00:15:56 < vampi-the-frog> oh just store it in a temp var
2017-11-11T00:16:13 < daey> yeah i thought it was doable in one line, would have been nice
2017-11-11T00:16:56 < qyx> then maybe (x = 0) return;
2017-11-11T00:17:41 < ohsix> like the difference between ++x and x++?
2017-11-11T00:17:41 < daey> doesnt return need the value on the left side?
2017-11-11T00:17:51 < daey> right*
2017-11-11T00:17:55 < ohsix> rvalue is x+1 on the left, x on the right
2017-11-11T00:18:22 < ohsix> i think assignment returns the assigned bit

2017-11-11T00:24:59 < ohsix> i think even if you find a way to do the 'old' return value, it will just be getting the compiler to use a temporary on your behalf, it's clearer to just do that

2017-11-11T00:30:57 < upgrdman> ohsix, maybe you'll know the answer to this question that nobody answered in ##opengl:
2017-11-11T00:31:06 < upgrdman> <upgrdman> not sure if this is common with opengl, or is a bug in my code, or a bug in the java lib im using (JOGL). when resizing my window, the canvas i draw on is resized maybe a frame later. i have vsync enabled, and im literally drawing one triangle, so i dont think im swaping the gpu. here's what it looks like: http://www.farrellf.com/temp/jogl_not_redrawing_in_sync_with_jframe_size.mp4
2017-11-11T00:31:07 < upgrdman> <upgrdman> swamping*
2017-11-11T00:31:07 < upgrdman> <upgrdman> notice the black regions when i resize the window, which go away a frame later.
2017-11-11T00:32:10 < ohsix> it's sort of unrelated to gl, but to solve it you need to do handle expose/draw events for that area; and probably resize the gl area explicitly instead of waiting for jogl or something to adapt to the window size on next frame
2017-11-11T00:32:18 < ohsix> gl is just 'on top' of shit
2017-11-11T00:32:39 < upgrdman> hmm
2017-11-11T00:33:03 < ohsix> it's a little different on windows with new stuff but not practically different for that problem
2017-11-11T00:33:22 < ohsix> on lunix too
2017-11-11T00:33:57 < ohsix> the window manager (win and loonix) are out of sync with all the drawing, and they just ask the backing window to repaint itself; the difference between that event and the next frame == an unpainted area
2017-11-11T00:34:12 < upgrdman> ya
2017-11-11T00:34:37 < upgrdman> i figured that much. but it looks like JOGL doesnt expose a way to fix this. i posted in their forum, so i'll see if anyone answers
2017-11-11T00:34:39 < ohsix> gl context has to resize too, but it sounds like that's handled a little already

2017-11-11T00:35:08 < upgrdman> ya i have a feeling resize() is called AFTER the resize occurs, so theres that one frame delay
2017-11-11T00:35:25 < ohsix> i dunno much about java, but find out how jogl sets up the event loop for that window, find out how it arranges the paint, then just find a way to hear the same message and manually resize
2017-11-11T00:35:26 < upgrdman> even turning off vsync only reduced, not fixed, the problem
2017-11-11T00:35:53 < ohsix> vsync off just means you see 200 hundred frames instead of 60 :p
2017-11-11T00:35:59 < upgrdman> yes :)

2017-11-11T00:40:18 < ohsix> it looks like jogl has a native window output
2017-11-11T00:40:28 < ohsix> so the code to handle paints is going to be in c
2017-11-11T00:49:31 < upgrdman> ohsix, modern desktops use opengl/dx to render windows. do you know how they manage to always render the GUI at 60Hz even if some program is maxing out the GPU and rendering at 5Hz?
2017-11-11T00:49:55 < upgrdman> e.g. no matter what, you can always see your mouse cursor moving at 60Hz, even if your program is crawling by at 5fps

2017-11-11T01:08:32 < daey> why wouldnt they be stored? if i use said define in a function, the program needs to know about it during runtime so it has to store it, doesnt it?
2017-11-11T01:09:35 < upgrdman> > theyre basically automated copy-n-paste.
2017-11-11T01:09:41 < Steffanx> ^
2017-11-11T01:10:05 < daey> yeah but in one case it ends up as if (12.45 > x) and in the other as if(12 > x)
2017-11-11T01:10:26 < Ultrasauce> it sounds an awful lot like you want a constant and not a define

2017-11-11T01:11:10 < Steffanx> Stop cock obsession upgrdman -_-
2017-11-11T01:11:33 < upgrdman> const int civilized_conversations = 69;
2017-11-11T01:11:49 < Steffanx> 123
2017-11-11T01:13:35 < daey> with const, do i need to enforce that the calculation is done in float and the conversation to int done at the end?
2017-11-11T01:14:22 < upgrdman> wtf
2017-11-11T01:15:27 < upgrdman> if you have "const int foo = 3;" you can use foo exactly like you would if it was not const, except it must always be an rvalue.
2017-11-11T01:19:52 < daey> i was refering to something like 'const int foo = 1 * 0.1 * 20;'
2017-11-11T01:20:03 < daey> it seems to work as expected though meaning foo ends up being 2

2017-11-11T02:37:07 < Cracki> now why do you think that is so?
2017-11-11T02:37:29 < Cracki> your initial confusion suggests you expected something else

2017-11-11T02:41:47 < daey> Cracki: well seeing that the result is an int, one could assume that the whole calculation might be done in int. maybe i have to cast every member of the calculation to (float) and the endresult to (int) again
2017-11-11T02:42:22 < Cracki> that's not how it works
2017-11-11T02:42:29 < Cracki> * is a binary operation
2017-11-11T02:42:30 < daey> yes i noticed
2017-11-11T02:42:45 < Cracki> if the operands are not of the same type, they're promoted up a hierarchy until they are
2017-11-11T02:43:08 < Cracki> when you write "1", that's initially an int (I think...)
2017-11-11T02:43:11 < daey> that was the piece i was missing
2017-11-11T02:43:21 < Cracki> and float is higher than int
2017-11-11T02:43:52 < Cracki> so what you get is the right side evaluating to 2.0 (float)
2017-11-11T02:44:05 < Cracki> which then is cast to int for the assignment
2017-11-11T02:44:12 < Cracki> that "foo" is const, doesn't matter there.

2017-11-11T02:44:52 < Cracki> there will still be some memory for that variable
2017-11-11T02:44:57 < Cracki> you just aren't allowed to change it
2017-11-11T02:45:21 < Cracki> (the memory exists because you can get a pointer to it)
2017-11-11T02:46:21 < daey> i found a scenario in which you run into trouble though
2017-11-11T02:47:18 < daey> const uint8_t long_press_ovf = ( long_press*F_CPU / (256 * 1024) ); this errors out. i assume because 256 and 1024 are both int. but the result of their multiplication is larger than what int can take. (its not promoting them)
2017-11-11T02:47:29 < Cracki> errors out?
2017-11-11T02:47:40 < Cracki> what's long_press?
2017-11-11T02:47:44 < Cracki> what's F_CPU?
2017-11-11T02:47:59 < Cracki> what's the base type on this architecture?
2017-11-11T02:48:00 < daey> long_press is a float. F_CPU is a UL
2017-11-11T02:48:07 < daey> 8bit avr
2017-11-11T02:48:19 < Cracki> avrgcc ints are 16 bit
2017-11-11T02:48:24 < daey> its easily fixable by removing the brackets around the 256*1024
2017-11-11T02:48:31 < Cracki> uh
2017-11-11T02:48:33 < Cracki> don't do that
2017-11-11T02:48:48 < daey> why not? they are useless
2017-11-11T02:48:51 < Cracki> rather make the right side UL
2017-11-11T02:49:21 < Cracki> well since it's gonna be float anyway, and optimizable at compile time, you're right, doesn't make a difference
2017-11-11T02:49:32 < daey> well by removing the brackets i assume they are getting promoted because the long_press promotes everything to float
2017-11-11T02:49:40 < Cracki> right
2017-11-11T02:50:05 < Cracki> in side the paren, it'd be 256k which doesn't fit inside a 16 bit int
2017-11-11T02:50:21 < daey> yeah.

2017-11-11T15:08:16 < jpa-> hm, smbus is surprisingly annoying to drive with generic i2c-usb adapters; it uses clock stretching, and also has a 35 us timeout, so any usb latency tends to ruin it
2017-11-11T15:08:29 < zyp> heh
2017-11-11T15:08:52 < jpa-> only adafruit's ft232h library is smart enough to buffer all the data so that it goes onto the wire without delays, but even then i had to hack extra delays in there to account for the clock stretching
2017-11-11T15:09:28 < jpa-> tried to figure out why laptop battery angry; but turns out all interesting registers are behind a password, which is not the default one
2017-11-11T15:09:56 < zyp> speaking of adapters, I'm thinking about making a simple usb to whatever thing

2017-11-11T15:10:20 < zyp> no

2017-11-11T15:43:00 < dekar> I think I've dumped this here before, but just in case I didn't. It's a thread-safe circular buffer lib that supports zero-copy operation for use with DMA: https://github.com/EliasOenal/etools/blob/master/ecbuff.h

2017-11-11T15:47:10 < dekar> We've used it for several projects and I consider it stable and well tested.

2017-11-11T15:51:50 < dekar> I guess. But github also doesn't know public domain, which basically means no license, because no copyright.
2017-11-11T15:52:24 < dekar> I could select the unlicense, which is related.
2017-11-11T15:52:34 < karlp> well, a readme maybe then.
2017-11-11T15:52:55 < karlp> the LICENSE filename doens't have to be a _license_ just a convention for knowing what the hell the plan is :)

2017-11-11T15:54:14 < fenugrec> dekar have you tried C11 atomics recently ? Last I tried, gcc generated invalid code for M0 targets
2017-11-11T15:56:50 < dekar> fenugrec, it's still on my todo list, but I didn't try it yet. Did you test clang?
2017-11-11T15:58:30 < fenugrec> dekar nah, I wanted to stay with gcc but I should've tried.
2017-11-11T15:58:42 < fenugrec> https://answers.launchpad.net/gcc-arm-embedded/+question/265649
2017-11-11T15:59:55 < dekar> One of our firmwares builds with either, so if I find the time I'll try.
2017-11-11T15:59:56 < fenugrec> gcc is (was) generating a ldrb + mov + strb sequence for a single atomic operation... which is problematic. Hopefully it treats sigatomic_t better
2017-11-11T16:11:35 < dekar> fenugrec, from what I remember sig_atomic_t was just an int on my toolchain. And my implementation only requires atomic reads, as well as writes, but not atomic manipulations, since the read- and write-pointers only have one thread writing them respectively.
2017-11-11T16:15:20 < dekar> That's the beauty of a circular buffer, one thread moves the head pointer, while the other moves the tail.

2017-11-11T22:22:33 < Steffanx> 340euro ish
2017-11-11T22:22:55 < zyp> I haven't been following the conversation, did you get it yet?

2017-11-11T22:29:43 < Steffanx> PaulFertser: the bed is just some aluminuimish pcb that says cr-10
2017-11-11T22:29:53 < PaulFertser> Steffanx: how long does it take to heat up to 110C?
2017-11-11T22:30:08 < Steffanx> With those fancy paper clipper to attach to glass
2017-11-11T22:30:12 < Steffanx> Bed temp?
2017-11-11T22:31:05 < Steffanx> 60 takes quite a few minutes, too long imho PaulFertser
2017-11-11T22:31:50 < Steffanx> So for now i just enable the ple preheat in the menu and prepare the print on my pc
2017-11-11T22:31:57 < Steffanx> Pla*
2017-11-11T22:32:25 < PaulFertser> Steffanx: yes, bed temp. I'm using 110C to print ABS. Takes some 10 minutes probably but I've heat insulated it a bit.
2017-11-11T22:34:41 < Steffanx> PaulFertser: im not even sure it will even reach 110c. When i tried 60 it seemed to struggle with that
2017-11-11T22:35:40 < Steffanx> The dutch PLA manufacturer advices 20-35C so not sure ill really need 60c anyway
2017-11-11T22:36:38 < zyp> I don't even have a heated bed
2017-11-11T22:37:12 < zyp> then again, I tend to get curling in the corners :p, so I'm not saying it's not required :p
2017-11-11T22:37:51 < PaulFertser> Heated bed allows to print without bothering much about preparing the surface though. And with abs the parts grab to it relatively nice while it's heated and then you just take them off (no drag at all) after they cool.
2017-11-11T22:42:59 < Steffanx> I wont use ABS anytime soon. The smell of the PLA that came with the printer was terrible enough
2017-11-11T22:43:19 < Steffanx> New dutch PLA's smell isnt as bad
2017-11-11T22:43:32 < PaulFertser> It seems you just go to another room and the smell is not noticeable.
2017-11-11T22:44:55 < Steffanx> Hah yes, but.. that wont work atm

2017-11-11T22:49:46 < zyp> probably a bunch
2017-11-11T22:49:53 < zyp> want me to do a test?
2017-11-11T22:51:07 < Laurenceb_> https://imgur.com/OuJLTOJ
2017-11-11T22:52:35 < zyp> ok, started the print
2017-11-11T22:56:41 < PaulFertser> For abs I came to the conclusion that I either need to go down to 220C or to enable cooling, or it's too leaky. But that doesn't work for normal prints. I also noticed that "external perimeters first" should be disabled for this test.
2017-11-11T22:57:33 < zyp> okay, I have external perimeters first enabled
2017-11-11T22:57:42 < zyp> printing PETG at 240C
2017-11-11T22:58:00 < PaulFertser> We'll see. I do not have means to take photos atm but I'll share tomorrow.

2017-11-11T23:06:22 < zyp> uh, good question
2017-11-11T23:07:08 < zyp> base speed is 60 mm/s, but I'm not sure if that applies
2017-11-11T23:07:32 < zyp> slicer is set to 130mm/s for travel moves, but I don't think firmware allows that much
2017-11-11T23:08:40 < zyp> ok, done
2017-11-11T23:08:42 < bvernoux> does anyone have good links for a good XYZ Table ?
2017-11-11T23:09:06 < bvernoux> maybe hacking a 3D printer could do the trick too ...
2017-11-11T23:09:40 < PaulFertser> I have about the same and those cones print for ~8 mins. Ok then, let's see tomorrow how the extremely cheap a8 compares.
2017-11-11T23:11:17 < zyp> this took 17 minutes with heating
2017-11-11T23:11:59 < zyp> https://bin.jvnv.net/file/vqLe9.JPG https://bin.jvnv.net/file/r0YM6.JPG
2017-11-11T23:12:01 < PaulFertser> Hm, I didn't take heating into account. Extruder goes to target temp in a minute or two.
2017-11-11T23:12:22 < Steffanx> Im printing it as well, for fun.
2017-11-11T23:12:36 < Steffanx> will take 10 minutes according to Cura

2017-11-11T23:13:41 < PaulFertser> zyp: those big "extensions" are probably due to external perimeters last in your test.

2017-11-12T01:34:12 < englishman> depends on who you go to
2017-11-12T01:35:50 < Cracki_> anything cheaper than dirtypcb?
2017-11-12T01:36:03 < englishman> allpcb
2017-11-12T01:36:06 < englishman> slightly
2017-11-12T01:36:11 < englishman> wont get much cheaper than tha ttho
2017-11-12T01:36:22 < englishman> its already pretty cheap dude
2017-11-12T01:38:17 < Jak_o_Shadows> I'm starting to wish I had made a PCB for the christmas lights.
2017-11-12T01:38:36 < Jak_o_Shadows> 8 more protoboards, with 8 components each, and a handful of tracks
2017-11-12T01:38:45 < Cracki_> good good
2017-11-12T01:39:02 < Cracki_> oh looky, allpcb has assembly
2017-11-12T01:43:02 < Cracki_> wow they're cheap
2017-11-12T01:43:15 < Cracki_> 100x100mm 10pcs still 5 usd

2017-11-12T01:49:48 < Cracki_> I guess that's the ultra-mainstream option. deviations quickly cost more. dirtypcbs can't seem to match this price dumping option
2017-11-12T01:51:27 < Cracki_> pcbway ~= allpcb, it seems

2017-11-12T02:07:46 < kOStiX> hey guys, why could it be that, say i have running 3 timer interrupts on an stm32f407, and suddenly randomly while using the application, it happens that the highest priority interrupt keeps running, but everything else seems to stop executing, no lower interrupts and neither the main while loop gets time
2017-11-12T02:07:53 < kOStiX> it happens randomly
2017-11-12T02:08:18 < kOStiX> any ideas?
2017-11-12T02:13:26 < Cracki_> how can you debug that
2017-11-12T02:13:39 < Cracki_> does the interrupt always return
2017-11-12T02:13:41 < kOStiX> its what im wondering
2017-11-12T02:13:47 < Cracki_> could the code be corrupted at runtime
2017-11-12T02:13:49 < kOStiX> usually everything runs fine
2017-11-12T02:13:55 < Cracki_> can you do instruction tracing
2017-11-12T02:13:55 < kOStiX> everything gets processing time
2017-11-12T02:14:03 < Cracki_> what kind of tracing can you do
2017-11-12T02:14:19 < Cracki_> can you singlestep, can you break into this deadlocked state?
2017-11-12T02:14:43 < Cracki_> are there interrupt flags that need clearing
2017-11-12T02:14:46 < kOStiX> to tellyou the truth i havent used much of tracing
2017-11-12T02:14:52 < kOStiX> flags are cleared
2017-11-12T02:15:06 < Cracki_> break execution, singlestep for a bit
2017-11-12T02:15:09 < kOStiX> as i say its kinda random, might now happen, then suddenly does
2017-11-12T02:15:17 < Cracki_> when it does, break
2017-11-12T02:15:18 < kOStiX> so its really hard to catch it
2017-11-12T02:15:29 < Cracki_> keep a debugger attached
2017-11-12T02:15:47 < kOStiX> yeah, im running it with stlink
2017-11-12T02:16:43 < Cracki_> they really shouldn't have named it so close to "stink"
2017-11-12T02:16:55 < kOStiX> hahah
2017-11-12T02:17:04 < kOStiX> well its what i got at hand hehe cheap one

2017-11-12T03:09:50 < kakimir> but anyway those are meant to be disosable bulk

2017-11-12T03:11:24 < Cracki_> eh, since they're military, they probably have the keys to full resolution GPS
2017-11-12T03:11:36 < kakimir> no way they use absolute data
2017-11-12T03:11:42 < Cracki_> GPS + IMU

2017-11-12T03:13:03 < Laurenceb_> youtube commentsdeliver
2017-11-12T03:15:03 < Laurenceb_> I see lots of dead drones
2017-11-12T03:15:07 < Laurenceb_> they light up red
2017-11-12T03:16:09 < Cracki_> saw one so far
2017-11-12T03:16:28 < Cracki_> the green ones do look unorderly when swarming towards their target points
2017-11-12T03:17:08 < Cracki_> guess that's to be expected for winged critters, as opposed to quadrotors and such
2017-11-12T03:17:19 < Laurenceb_> I wonder if they have no collision avoidance at all
2017-11-12T03:17:35 < Laurenceb_> theres lots of space up there and quite a few seem to die
2017-11-12T03:18:06 < Cracki_> if they're smart, they run on something like a time-divided channel
2017-11-12T03:18:29 < Cracki_> each pings its location, gathers all the others, does local decisions
2017-11-12T03:18:39 < Laurenceb_> hard to make it accurate enough
2017-11-12T03:18:44 < Cracki_> good enough
2017-11-12T03:18:46 < Laurenceb_> they seem to be <5maway from each other
2017-11-12T03:18:56 < Laurenceb_> might be doable with ir beacons and a camera
2017-11-12T03:18:59 < Cracki_> they're winged critters, theyre not as agile anyway
2017-11-12T03:19:08 < Laurenceb_> each one doesnt need 360degree vision
2017-11-12T03:19:13 < Cracki_> GPS+IMU can be quite good
2017-11-12T03:19:49 < Cracki_> I wonder how the intel drones for some football events did their swarming
2017-11-12T03:20:03 < Cracki_> they prolly deployed a radio-based local positioning system
2017-11-12T03:20:26 < Cracki_> anything based on optics is too fragile
2017-11-12T03:20:53 < Cracki_> cameras, except for fixed groundbased setups, is too expensive computaitonally
2017-11-12T03:37:27 < Cracki_> some academics tried positioning using camera and AR markers...
2017-11-12T03:37:53 < Cracki_> camera angle tended to be shit, resolution shit too, so the operating range was narrow
2017-11-12T03:38:39 < Cracki_> it was good for landing maneuvers though, very accurate positioning
2017-11-12T03:50:03 < kOStiX> so, how do i define different callback functions for 2 timers, both triggering interrupts at update event? the interrupt handler function calls the same callback defined for the update event
2017-11-12T03:52:19 < kOStiX> or i have to check for what source its coming from within the update event callback?
2017-11-12T03:54:55 < Jak_o_Shadows> (sorry to interrupt) My external |LSE is not working - code is correct, it works on a differetn board. oscope shows that it's pretty wrong - no signal really (but it does have a voltage). Can I use the HSE with accuracy? Or is the issue that with a 20 bit prescaler, I can't scale enogh?

2017-11-12T17:32:40 < dongs> makes sense
2017-11-12T17:32:50 < kakimir> tpw_rules: you can trigger Laurenceb then
2017-11-12T17:42:58 < ReadErr> lol tpw_rules took the bait
2017-11-12T17:48:10 < ReadErr> tpw_rules: you can resize lvms online
2017-11-12T17:48:21 < ReadErr> do it all the time, going up in size
2017-11-12T17:49:01 < kakimir> I have 2 wireless routers connected with 100 duplex
2017-11-12T17:49:18 < kakimir> how do I create one wifi network of them 2 routers
2017-11-12T17:49:26 < kakimir> so that it is seamless
2017-11-12T17:49:27 < ReadErr> what kind of garbage doesnt have gbit
2017-11-12T17:49:33 < ReadErr> wifi is faster than 100mbit
2017-11-12T17:49:38 < tpw_rules> ReadErr: but you can't do a) ntfs or b) shrink
2017-11-12T17:49:39 < kakimir> sure
2017-11-12T17:49:56 < ReadErr> tpw_rules: ive done windows
2017-11-12T17:50:09 < ReadErr> you just right click and extend
2017-11-12T17:50:15 < tpw_rules> is that shrink
2017-11-12T17:50:21 < kakimir> my other router has 100duplex ports and my media converters are 100duplex
2017-11-12T17:50:29 < ReadErr> you said 'or'
2017-11-12T17:50:53 < tpw_rules> can ntfs be online expanded?
2017-11-12T17:50:58 < ReadErr> yes
2017-11-12T17:51:28 < kakimir> anyways the speed of far reach of the network is not a problem
2017-11-12T17:51:32 < tpw_rules> oh, i wasn't aware
2017-11-12T17:51:39 < kakimir> 100M is more than good at that corner
2017-11-12T17:52:09 < ReadErr> shrinking a disk is dumb, easier to do a filelevel xfer
2017-11-12T17:52:24 < tpw_rules> or just reinstall windows
2017-11-12T17:53:21 < ReadErr> why would i reinstall to the same disk
2017-11-12T17:53:24 < ReadErr> thats dmb
2017-11-12T17:53:33 < tpw_rules> he's trying to shrink a fresh windows install then copy it to another disk
2017-11-12T17:54:28 < kakimir> do not get worked about it

2017-11-12T22:44:26 < mtbg> the reason probably is, energy efficient and highly integrated socs with arm cores were widely available before alike x86 based ones

2017-11-12T22:45:31 < mtbg> and even now there is wider choice of them

2017-11-13T00:30:44 < Steffanx> How can one have a pink phone
2017-11-13T00:30:52 < englishman> it's hard, they are sold out everywhere
2017-11-13T00:31:01 < englishman> so, luck, i guess
2017-11-13T00:31:09 < Steffanx> Is ReadErr your english"wife"?
2017-11-13T00:31:25 < kakimir> friend said that he saw young lads in their fancy baverian pants taking pee under some tree that had drank so much beer there was no life in their eyes

2017-11-13T00:31:47 < englishman> oh they are still in stock
2017-11-13T00:31:51 < Steffanx> Nevermind, this is going nowhere englishbot englishbot :P
2017-11-13T00:31:51 < englishman> so you just have to order one
2017-11-13T00:31:54 < englishman> and then you have a pink phone
2017-11-13T00:31:56 < englishman> easy
2017-11-13T00:31:56 < Steffanx> englishman: *
2017-11-13T00:32:15 < kakimir> I have pink phone.. didn't get to choose
2017-11-13T00:32:51 < englishman> readerror would make a nice wife but im not into black men

2017-11-13T08:58:31 < hesperaux> on another note: has anyone had issues using ST's SPL where if you configure a few pins on GPIOB for one thing and then try to enable an external interrupt on a different GPIOB pin, the interrupt happens repeatedly without being externally triggered?
2017-11-13T08:59:06 < hesperaux> I cannot figure out what's going on...it's something with the pin, because if I switch it to PA0 it works fine

2017-11-13T10:37:23 < ohsix> most/~all will be satisfactory and you'll have tons ;]

2017-11-13T10:37:46 < ohsix> eh

2017-11-13T10:39:06 < ohsix> that's a hard ass criteria to meet
2017-11-13T10:41:04 < ohsix> or, i guess; you could also mean containers small enough that you basically use them all up whenever you open one, and many containers

2017-11-13T10:42:28 < jadew> seems other people are recommending it too, so that's reassuring
2017-11-13T10:45:38 < ohsix> my friends recommended jumping off a bridge but i didn't trust them
2017-11-13T10:46:42 < jadew> well, recoommendations are good, but you have to try it for youreself if you want to form an opinion on it
2017-11-13T10:50:49 < hesperaux> ok, can you not read an input pin while it is configured as an EXTI interrupt source?
2017-11-13T10:51:20 < hesperaux> because calling GPIO_ReadInputDataBit(port,pin) on the pin while in the ISR returns 0 (pressed) no matter what
2017-11-13T10:55:51 < hesperaux> ...turns out if you are stupid and set the pin to 0 instead of GPIO_Pin_0, it of course doesn't work

2017-11-13T11:34:48 < hesperaux> even though they use assert_param
2017-11-13T11:35:28 < PaulFertser> ST shit-library does it runtime, and so it's disabled by default.
2017-11-13T11:36:39 < hesperaux> well, such is life
2017-11-13T11:37:06 < hesperaux> I still can't figure out why using some pins for my EXTI interrupt totally jacks up the thing
2017-11-13T11:38:48 < PaulFertser> You have choice though. There're independent libarary implementations. E.g. stm32plus or cortex-m crates in Rust.
2017-11-13T11:39:05 < hesperaux> crates in Rust?
2017-11-13T11:39:23 < PaulFertser> EXTI module doesn't affect GPIO pins anyhow as far as I know, they continue to work as normal.
2017-11-13T11:39:31 < PaulFertser> crates == additional libraries
2017-11-13T11:39:34 < hesperaux> ah
2017-11-13T11:43:36 < hesperaux> yeah no idea what's up, but if I set certain pins up for an EXTI interrupt, they trigger incessantly
2017-11-13T11:43:41 < hesperaux> same code with other pins works great
2017-11-13T11:47:23 < c4017_> I seem to remember having problems where both NVIC and EXTI interrupt flags had to be cleared or the ISR would keep looping
2017-11-13T11:47:45 < hesperaux> I actually tried doing that
2017-11-13T11:48:51 < PaulFertser> There's a known gotcha about clearing interrupt flags too late, just before an ISR handler returns, then it sometimes triggers for the second time. But I think that can happen only twice in a row.
2017-11-13T11:49:39 < hesperaux> good to know
2017-11-13T11:50:09 < hesperaux> for several of the pins, they were triggering at odd rates. It was like there was noise on the line, but I don't think there is
2017-11-13T11:51:21 < c4017_> Was the new pin accidentally configured for logic level interrupt instead of edge triggered?
2017-11-13T11:51:47 < hesperaux> I don't think so, because that code was identical for any pins I used
2017-11-13T11:51:49 < PaulFertser> So you need to clear the corresponding EXTI bit somewhere at the beginning of the handler, and if it's really too short (e.g. two instructions), add a nop or two after that even.
2017-11-13T11:52:15 < PaulFertser> c4017_: I do not think EXTI supports level triggering, at least not on stm32f1, does it have that on other famalies?
2017-11-13T11:52:38 < c4017_> I think it has low level trigger on f4
2017-11-13T11:52:44 < c4017_> might be mistaken
2017-11-13T11:53:00 < hesperaux> this is a f103 and the only trigger options are rising, falling, or both

2017-11-13T11:56:51 < zyp> PaulFertser, wouldn't it be better to insert a barrier rather than a nop?

2017-11-13T11:58:36 < PaulFertser> zyp: does barrier account for AHB-APB delays? I know about memory barriers intrinsics, but those are not suitable certainly. Forcing a readback makes sense but it's hard to write it in a way that wouldn't cause any compiler warnings probably?
2017-11-13T11:58:52 < zyp> (void)reg;
2017-11-13T11:59:34 < zyp> it's the same pattern used to silence unused variable warnings
2017-11-13T11:59:48 < zyp> but since the register is volatile, the read itself can't be optimized out

2017-11-13T12:02:17 < PaulFertser> That's the nicest solution then, it seems.
2017-11-13T12:02:49 < PaulFertser> I never needed an ISR handler that short, just paraphrasing what I've seen recommended by clive1 on forums or somesuch.

2017-11-13T12:05:03 < zyp> hmm, wonder if pipelining could let it take the branch before the result of the last read has arrived
2017-11-13T12:05:46 < zyp> the branch operation doesn't depend on the result of that
2017-11-13T12:08:29 < zyp> huh
2017-11-13T12:08:36 < zyp> regarding barriers: "All use of DMB is redundant due to the inherent ordering of all loads and stores on Cortex-M3 and Cortex-M4."
2017-11-13T12:10:37 < kakimir> should I put anything into N connector thread and seal?

2017-11-13T12:14:13 < hesperaux> PaulFertser, thanks. I'm bookmarking that
2017-11-13T12:14:43 < PaulFertser> hesperaux: though it likely is unrelated to your issues
2017-11-13T12:15:12 < hesperaux> PaulFertser, agreed. in my case the triggering continous, and not completely periodically either
2017-11-13T12:16:00 < PaulFertser> hesperaux: probably you really do have those edges on those pins?
2017-11-13T12:16:16 < hesperaux> I should hook up a scope
2017-11-13T12:16:30 < hesperaux> so far I've only used a logic analyzer
2017-11-13T12:16:42 < hesperaux> i'll do it now because now I really want to know
2017-11-13T12:16:55 < zyp> hesperaux, is it trigging often enough that normal code can't execute?
2017-11-13T12:17:14 < hesperaux> zyp, not quite, but it messes up my LCD, so kind of
2017-11-13T12:26:21 < hesperaux> now on this one it's just not triggering...sigh...I probably messed up something

2017-11-13T13:16:31 < mtbg> zyp: they probably meant it is redundant in "normal" computation, not when memory writes can change program flow in a hidden manner
2017-11-13T13:16:45 < mtbg> as with that interrupt flags
2017-11-13T13:19:13 < kakimir> while I'm booted in linux shouldn't I clone the drive there?
2017-11-13T13:19:17 < zyp> no, they mean redundant as in it won't make a difference
2017-11-13T13:19:24 < kakimir> just dd it
2017-11-13T13:19:34 < kakimir> get boot sector and shit
2017-11-13T13:19:45 < kakimir> simples?
2017-11-13T13:19:47 < zyp> kakimir, what are you talking about?
2017-11-13T13:20:08 < kakimir> I think I have done dd clones multiple times that actually boot right away
2017-11-13T13:20:27 < kakimir> I'm resizing ntfs
2017-11-13T13:20:30 < kakimir> for ssd
2017-11-13T13:21:50 < kakimir> booted linux and now gparted is shrinking drives
2017-11-13T13:21:58 < kakimir> internal hdd
2017-11-13T13:22:09 < kakimir> then dd to esata ssd
2017-11-13T13:22:10 < zyp> resizing ntfs in linux sounds unpleasant
2017-11-13T13:22:12 < mtbg> in cm4 programming manual there were several examples where they were turning global interrupts on and issuing dsb first
2017-11-13T13:22:42 < mtbg> was it copied from earlier manuals for the cores that need this?
2017-11-13T13:23:17 < zyp> mtbg, dsb and dmb are separate instructions
2017-11-13T13:23:38 < kakimir> zyp: it's actually really handy
2017-11-13T13:24:08 < mtbg> ok then
2017-11-13T13:25:42 < zyp> mtbg, as far as I can see, DMB ensures that any memory accesses before the DMB are performed before any memory accesses after the DMB

2017-11-13T13:26:35 < zyp> while DSB ensures that no other instructions at all are executed until all pending memory accesses are performed
2017-11-13T13:27:46 < mtbg> makes sense
2017-11-13T13:28:03 < zyp> yeah
2017-11-13T13:28:06 < mtbg> so dmb wouldn't suffice for that interrupt case
2017-11-13T13:28:21 < zyp> correct, dsb would be the appropriate barrier
2017-11-13T13:28:40 < zyp> and dmb is redundant because all memory accesses are performed in-order anyway
2017-11-13T13:29:06 < zyp> so dmb is probably a no-op in hardware, just existing for binary compatibility
2017-11-13T13:29:32 < zyp> maybe it's useful on M7, the document I read seemed to be older than M7
2017-11-13T13:29:40 < kakimir> https://www.savjee.be/2012/10/creating-one-WiFi-network-with-multiple-access-points/ is it really so easy?
2017-11-13T13:30:03 < zyp> sure
2017-11-13T13:30:40 < zyp> if you have multiple APs with same ssid and auth settings, clients would pick whichever has a stronger signal
2017-11-13T13:31:25 < zyp> and once you're connected, they're all on the same L2 segment
2017-11-13T13:31:39 < kakimir> is it seamless to client?
2017-11-13T13:31:52 < zyp> define seamless
2017-11-13T13:32:11 < kakimir> so that my ip and shit won't change?
2017-11-13T13:32:39 < kakimir> can I use same channel for both routers+
2017-11-13T13:32:44 < zyp> as long as the APs are plain APs just bridging and you have a separate DHCP then yes
2017-11-13T13:33:01 < zyp> DHCP will see the same MAC regardless of which AP you connect to and hand out same ip
2017-11-13T13:33:23 < kakimir> how about channel?
2017-11-13T13:33:35 < zyp> the only non-seamless thing is when a client switches from one to the other, there might be a short interrupting while ARP tables update
2017-11-13T13:33:55 < kakimir> I have channel 3 for my link and channel 11 for local wifi
2017-11-13T13:34:01 < zyp> pro stuff have some handover logic to fix that
2017-11-13T13:34:21 < zyp> you'll probably not notice anyway unless you're doing voip while roaming between APs
2017-11-13T13:34:22 < kakimir> pro stuff as in network adapter or as in routers
2017-11-13T13:34:30 < zyp> pro AP systems
2017-11-13T13:34:54 < zyp> same channel is probably a bad idea
2017-11-13T13:35:18 < PaulFertser> kakimir: you might want FT (?) extensions for faster roaming. 802.11r, 802.11k
2017-11-13T13:35:44 < zyp> not worse than using same channel as your neighbor, but still dumb enough that it removes part of the point of having multiple APs
2017-11-13T13:36:34 < PaulFertser> kakimir: https://wiki.openwrt.org/doc/uci/wireless#fast_bss_transition_options
2017-11-13T13:36:54 < kakimir> so I need to go from 40Mhz band to 20mhz band to fit the channels
2017-11-13T13:37:07 < PaulFertser> Works on hostapd level so available on any non-pro systems too.
2017-11-13T13:38:00 < zyp> kakimir, that doesn't sound very beneficial either
2017-11-13T13:38:08 < zyp> why do you want two APs in the first place?

2017-11-13T13:39:14 < kakimir> and router to another end of building is a kind of side effect too
2017-11-13T13:39:24 < zyp> if you've only got one significant client then there won't be much traffic on both APs at the same time

2017-11-13T13:45:28 < mtbg> there was a beacon spammer on esp8266 that someone wrote, I guess it would jam most client connection attempts if would broadcast the same settings and ssids as real networks in the area, only differing in bssid

2017-11-13T15:52:37 < aandrew> first they have a human review the pic to see if it qualifies as a nude or the type of pic that would be used for revenge porn
2017-11-13T15:52:48 < aandrew> if it does, it's hashed and the pic destroyed
2017-11-13T15:52:54 < aandrew> so yeah, totally trust facebook man

2017-11-13T15:59:50 < jadew> yeah, they vibrated the obese (with normal blood pressure) and lean women and observed that the obese have different blood flow changes and neural responses
2017-11-13T16:00:11 < Laurenceb> fat lives matter
2017-11-13T16:00:17 < jadew> I bet the difference in blood flow is because of how those waves press against the veins
2017-11-13T16:00:35 < jadew> and the neural response is a reaction to that
2017-11-13T16:01:04 < jadew> or it could be a matter of wavelength
2017-11-13T16:01:12 < jadew> the fatties are resonant to lower frequencies

2017-11-13T16:05:00 < jadew> they hooked up an obese women to the machine and played with the frequency knob until she started looking like a blow fish
2017-11-13T16:10:10 < mtbg> lower frequencies and lower Q
2017-11-13T16:11:24 < BrainDamage> maybe it wasn't a vibrating platter, rather a vibrator
2017-11-13T16:14:12 < jadew> sort of like a waveguide probe?

2017-11-13T18:35:18 < BrainDamage> and even more funny is that the statistics for corruption overall are more or less in line with rest of eu, but because of the ridicolous exploits of the organized crime, the perceived corruption here ( from italians, to italians ) is ~50% higher than other countries

2017-11-13T21:08:15 < kakimir> do you use reference regulator with wheatstone amplifiers?
2017-11-13T21:09:10 < BrainDam1> is your wheatstone dc or ac?
2017-11-13T21:09:18 < kakimir> dc
2017-11-13T21:09:39 < kakimir> is there ac wheatstone bridges?
2017-11-13T21:09:44 < BrainDam1> ofc
2017-11-13T21:10:04 < BrainDam1> it's to minimize 1/f noise
2017-11-13T21:10:34 < BrainDam1> but thenyou either need lock in or matched filter at the output
2017-11-13T21:10:36 < kakimir> interesting
2017-11-13T21:10:48 < BrainDam1> depending on what waveform you use
2017-11-13T21:10:55 < kakimir> I use hx711
2017-11-13T21:12:32 < englishman> we're all pink noise on the inside
2017-11-13T21:15:01 < upgrdman> that moment when you're porting someone code to a new MCU, and you see comments about how you "must not enable optimization or it break" and then you see stupid shit like this for(int i = 0; i < 100000; i++); ... ya, i wonder why you couldn't turn on optimization :/
2017-11-13T21:15:28 < BrainDam1> if you use dc whestone and don't have strict precision requirements go with reference regulator
2017-11-13T21:15:58 < kakimir> if I have strict precision requirements?
2017-11-13T21:16:00 < BrainDam1> otherwise you need to calculate the effect of psrr
2017-11-13T21:16:10 < kakimir> too hard
2017-11-13T21:16:25 < BrainDam1> which is often just psrr/2 if all resistors areequal
2017-11-13T21:16:27 < kakimir> how do I make AC wheatstone bridge?
2017-11-13T21:16:43 < kakimir> I don't know what to do with that calculation
2017-11-13T21:16:55 < BrainDam1> it's the same as dc, but psu is ac
2017-11-13T21:17:27 < BrainDam1> butt you need syncronous demodulation at the output
2017-11-13T21:18:36 < kakimir> and how that removes the noise?
2017-11-13T21:18:45 < kakimir> or make it less
2017-11-13T21:18:55 < BrainDam1> wibbly wobbly signal processing

2017-11-13T21:19:25 < BrainDam1> do you espect me to give you a signal processingcourse in 3 lines of irc?
2017-11-13T21:19:57 < BrainDam1> also whilst drunk and bored
2017-11-13T21:21:15 < BrainDam1> the shortest explanation i could think of is that you're seeing a narrowband signal, but shifting up in frequency you see lower background noise at higher than lower frews
2017-11-13T21:21:51 < BrainDam1> but anything past that is beyond my alcohol concentration limit
2017-11-13T21:23:24 < Ultrasauce> we all know drunk irc didactics is your specialty
2017-11-13T21:24:04 < BrainDam1> only when using your account
2017-11-13T21:26:01 < kakimir> BrainDam1: I think I understood
2017-11-13T21:26:32 < kakimir> but I think such wheatstone amplification is not what I need any day
2017-11-13T21:27:25 < kakimir> soon
2017-11-13T21:27:35 < kakimir> but good trivia
2017-11-13T21:27:38 < kakimir> when I need it
2017-11-13T21:27:52 < upgrdman> with "VSS" and "VDD" anyone know why they are called that? i mean, yes, source and drain. but why not VS and VD... why repeat the letter twice?
2017-11-13T21:28:12 < kakimir> I think it has been told here at least twice

2017-11-13T21:50:32 < zyp> nice
2017-11-13T21:50:38 < zyp> what printer do you have?
2017-11-13T21:50:52 < PaulFertser> Anet A8
2017-11-13T21:50:55 < zyp> ah
2017-11-13T21:51:16 < zyp> so mine's the worst of the lot :p
2017-11-13T21:51:28 < PaulFertser> Only the cones were printed after installing X axis frame braces, everything else was on stock.
2017-11-13T21:52:44 < zyp> mine's an old sumpod that I got from indiegogo in 2011, but never bothered assembling until this spring
2017-11-13T21:52:58 < PaulFertser> That trimmer line nylon is a bitch to print. I had to go up to 265 extruder temp to get reasonable mid-layer adhesion, it's stringy as hell and tends to warp as abs.
2017-11-13T21:53:11 < Ultrasauce> i hope you're ventilating, doing nylon

2017-11-13T21:55:43 < PaulFertser> Ultrasauce: yes, and that's without any post-processing. That SBS glass is actually transparent if treated with an appropriate solvent.

2017-11-13T21:56:29 < BrainDamage> why none of you is printing buttplugs
2017-11-13T21:56:31 < PaulFertser> Ultrasauce: (safety) I mean it's not really a lab test, but still?
2017-11-13T21:57:08 < Ultrasauce> i remember reading it was significant but that might have been one specific batch or something
2017-11-13T21:57:29 < PaulFertser> zyp: so yours has Bowden extruder, in theory that gives better quality or speed. Nice case for the spool!

2017-11-13T21:58:04 < sync> I hear that the spring rate in a bowden extruder is an issue
2017-11-13T21:58:34 < Ultrasauce> there's a tradeoff there. lower end effector mass but it affects retraction
2017-11-13T21:58:51 < zyp> I don't think it helps at all on my printer, carriage is heavy as fuck
2017-11-13T21:59:51 < Ultrasauce> https://www.youtube.com/watch?v=eJzeEk5_ky0 heres the only imagery i bothered to make of mine so far

2017-11-13T22:01:05 < Ultrasauce> yeah I should stop parroting that shit as fact
2017-11-13T22:01:32 < zyp> I picked up a bunch of parts to do a custom corexy design, I just haven't bothered actually designing it yet

2017-11-13T22:02:19 < upgrdman> so are you guys just 3d printering figurines or is there a grand plan?
2017-11-13T22:02:40 < BrainDamage> fetish models is where it's at
2017-11-13T22:02:44 < Ultrasauce> the resultant surface is too porous for dildos so
2017-11-13T22:02:48 < Ultrasauce> you gotta make dildo molds
2017-11-13T22:03:02 < BrainDamage> well, you can smooth the surface post-printing
2017-11-13T22:03:15 < BrainDamage> sand blasting, chemical etching, etc
2017-11-13T22:03:22 < upgrdman> acetone vapor, iirc?
2017-11-13T22:03:28 < zyp> upgrdman, most useful stuff I've printed have been enclosures
2017-11-13T22:03:30 < Ultrasauce> I tried acetone vapour, it sort of worked
2017-11-13T22:03:34 < BrainDamage> that'd fall under chemical etching
2017-11-13T22:03:54 < upgrdman> zyp, got any pix of neat enclosures?
2017-11-13T22:04:00 < PaulFertser> upgrdman: my plan was to have a limited amount of mechanical tinkering with something that is not my motorbike.

2017-11-13T22:05:54 < upgrdman> heh
2017-11-13T22:06:52 < BrainDamage> Ultrasauce: do you really need full 3dof or is it more for masturbatory practices?
2017-11-13T22:07:34 < Ultrasauce> definitely the latter
2017-11-13T22:08:03 < Ultrasauce> a more traditional azimuth-elevation 2dof gimbal would be fine for most applications
2017-11-13T22:08:20 < upgrdman> Ultrasauce, looks cool, but i must be missing something. why is that better than a gimbal?
2017-11-13T22:08:29 < Ultrasauce> just fuckin look at it dude
2017-11-13T22:08:36 < BrainDamage> because you don't have windup constrains
2017-11-13T22:10:24 < PaulFertser> (offtopic, mechanical curiosity, video) an unconventional CVT: http://world.honda.com/motorcycle-picturebook/HFT/detail/
2017-11-13T22:10:27 < Ultrasauce> a slightly less handwavey answer is that i want to get my head around parallel kinematics
2017-11-13T22:11:24 < BrainDamage> hydraulic swash plate is not that uncommon
2017-11-13T22:11:34 < BrainDamage> military vehicles actually often employ it
2017-11-13T22:12:21 < upgrdman> so i understand the purpose on a heli, but on a truck, what is a swashplate for?
2017-11-13T22:12:44 < PaulFertser> BrainDamage: do you have a link with more explanations? I actually can't really figure out how it works from the video. And I can't understand what range of "gear ratios" it gives.
2017-11-13T22:12:47 < zyp> angle of swatchplate determines exchange rate
2017-11-13T22:12:50 < zyp> I figure
2017-11-13T22:13:18 < BrainDamage> yup, that's pretty much there is
2017-11-13T22:13:35 < upgrdman> exchange rate?
2017-11-13T22:13:40 < BrainDamage> it's kind of like a cone cvt, except of being friction actuated, it's hydraulic actuated
2017-11-13T22:13:50 < upgrdman> o
2017-11-13T22:13:51 < BrainDamage> upgrdman: torque ratio
2017-11-13T22:16:35 < BrainDamage> there's some fancy smancy hydraulic cvt where power transmission happens entirely trough working fluid
2017-11-13T22:17:00 < upgrdman> and the benefit of that is the only thing that wears out is easily replaced fluid?
2017-11-13T22:17:20 < zyp> the benefit is CVT
2017-11-13T22:17:32 < upgrdman> yes yes cvt, but that TYPE of cvt
2017-11-13T22:17:32 < zyp> no need for fixed steps
2017-11-13T22:18:17 < BrainDamage> by not relying on friction your operation parameters are way more constant in operational lifetime
2017-11-13T22:18:31 < upgrdman> ah ok
2017-11-13T22:18:38 < BrainDamage> friction ones instead increasingly drift over time as the parts wear out
2017-11-13T22:21:36 < BrainDamage> semi unrelated, do you guys also get tinnitus when moderately drunk?
2017-11-13T22:21:38 < PaulFertser> Is it true that some car manufacturers made automatic CVT control use steps because of clueless drivers' complaints?
2017-11-13T22:21:49 < upgrdman> yez
2017-11-13T22:22:13 < upgrdman> my dad is one of those weirdos :(
2017-11-13T22:22:23 < BrainDamage> stepping 'cvt', makes for a much more predictable driving experience
2017-11-13T22:22:36 < kakimir> BrainDam1: hey I actually understood that ac bridge thing
2017-11-13T22:22:41 < upgrdman> "i can't tell when it's shifting!" yes... thats a good thing. "but, but ..."
2017-11-13T22:23:10 < kakimir> it effectivelly eliminates frequencies other than the "carrier"
2017-11-13T22:23:17 < kakimir> it tunes into it like a radio
2017-11-13T22:23:26 < sync> PaulFertser: when you absolutely positively need to have a shitty drivetrain efficiency :D
2017-11-13T22:23:28 < zyp> it's kinda weird to drive a car that doesn't shift when you're used to it
2017-11-13T22:23:49 < BrainDamage> it does work like a radio, in fact most radios are built upon matched filtering
2017-11-13T22:23:52 < zyp> I remember I really noticed that when I test drove the e-golf
2017-11-13T22:24:08 < zyp> but it was not hard to get used to it not having to shift
2017-11-13T22:24:26 < kakimir> it sure picks frequencies close to actual modulation
2017-11-13T22:24:40 < sync> zyp: yeah, that is the nice thing about hybrids
2017-11-13T22:24:48 < kakimir> but it is the design problem to pick the frequency so that there is less noise
2017-11-13T22:24:48 < BrainDamage> i forgot what's the name of the effect, when you pump the pedal and it downshifts to increase torque, if i had automatic transmission I'd abuse it all the time
2017-11-13T22:24:56 < kakimir> kickdown
2017-11-13T22:25:00 < zyp> sync, for hybrids, it depends
2017-11-13T22:25:10 < sync> or well, e cars, but yes
2017-11-13T22:25:14 < zyp> GTE has a traditional DSG transmission
2017-11-13T22:25:30 < sync> yeah, I wondered why they did that
2017-11-13T22:25:31 < BrainDamage> kakimir: typically you just pick whatever's highest viable frequency or something a bit past corner's
2017-11-13T22:25:39 < sync> but the dsg is not so bad
2017-11-13T22:25:47 < sync> I dislike the factory codez on it tho
2017-11-13T22:25:54 < zyp> haha
2017-11-13T22:25:55 < kakimir> what is highest viable frequency then`?
2017-11-13T22:25:58 < sync> with it's microslip strategy
2017-11-13T22:26:01 < kakimir> what are limiting factors?
2017-11-13T22:26:05 < sync> ~its
2017-11-13T22:26:13 < zyp> microslip?
2017-11-13T22:26:37 < BrainDamage> kakimir: depends on your modulator, the problem of electronic ones is that you get back what you were trying to get rid of, the 1/f noise
2017-11-13T22:26:44 < upgrdman> my electricity was acting up again, and this time long enough for me to definitively figure out why. using split-phase ac (usa) and one end is intermittent, but got intermittent enough that it's now open circuit.
2017-11-13T22:26:44 < sync> yes, it lets the clutch slip a leeeetle tiiiiny bit so that it feels "softer" when you modulate the throttle
2017-11-13T22:26:57 < zyp> oh, heh
2017-11-13T22:27:04 < upgrdman> lets see how long it takes SCE to come out and fix their end
2017-11-13T22:27:14 < BrainDamage> electromechanical ones typically don't suffer from 1/f, but are limited in frequency, and are rather awkward to use
2017-11-13T22:27:40 < BrainDamage> so they don't give _extra_ 1/f, but can only shift up typically less than fc
2017-11-13T22:27:50 < sync> I made a replacement electrohydraulic module for a DQ500 once
2017-11-13T22:27:57 < sync> just bangs in the gears
2017-11-13T22:28:04 < sync> no tq limit, no nothing
2017-11-13T22:28:06 < BrainDamage> whenever to pick one or the the other becoemes an optimization problem
2017-11-13T22:28:24 < BrainDamage> my personal reccomendation is that you don't give a shit in 99.9% of the cases
2017-11-13T22:28:38 < PaulFertser> I've read an article how a guy spent the whole summer trying to obtain some old shitty windows ce pda (rebranded to honda pocket tester) and then to get/buy/obtain anyhow the corresponding windows application for it. Just to understand what's going on with that HFT on his motorbike. It refused to enter swash plate calibration mode because it had zeroes stored there in ECU. Once he finally managed
2017-11-13T22:28:44 < PaulFertser> to learn that he fixed the issue by connecting the transmission computer to another bike and doing calibration there.
2017-11-13T22:28:59 < sync> just cmc clutch material
2017-11-13T22:29:01 < PaulFertser> But what the hell is with all those manufacturers not providing proper service manuals and service software to their customers?!
2017-11-13T22:29:18 < PaulFertser> I am sometimes really glad I have zero amount of firmware in my motorbike.
2017-11-13T22:29:25 < zyp> PaulFertser, better buy an open source bike
2017-11-13T22:29:36 < BrainDamage> 3d print your drivetrain
2017-11-13T22:29:43 < Ultrasauce> rms was right dot jpg
2017-11-13T22:30:01 < sync> hahaha PaulFertser
2017-11-13T22:30:04 < sync> yeah
2017-11-13T22:30:47 < sync> I prefer german cars because of that
2017-11-13T22:30:56 < sync> I can read the leaked internal bosch documents
2017-11-13T22:31:20 < PaulFertser> zyp: some people actually use megasquirt or other ECUs with open source.
2017-11-13T22:31:25 < upgrdman> is bosch the oem or parent?
2017-11-13T22:31:31 < zyp> PaulFertser, I used to
2017-11-13T22:31:32 < sync> oem
2017-11-13T22:31:51 < zyp> the old ECU in my old car were failing, so I replaced it with a megasquirt
2017-11-13T22:31:56 < PaulFertser> sync: hm, is it possible to get some "API docs" for a specific Bosch ESP/ABS module?
2017-11-13T22:32:29 < sync> unfortunately there is no funktionsrahmen for those
2017-11-13T22:32:35 < sync> but you can get the firmware
2017-11-13T22:32:36 < zyp> hmm, I think I drove it with megasquirt for seven years or so
2017-11-13T22:33:01 < BrainDamage> do you guys have emission testing?
2017-11-13T22:33:03 < PaulFertser> Was it hard to get working properly?
2017-11-13T22:33:13 < zyp> BrainDamage, yes, it failed first time I had it in
2017-11-13T22:33:14 < BrainDamage> because here custom ECU have an hard time passing the emission testing
2017-11-13T22:33:23 < BrainDamage> probably by lack of cheating
2017-11-13T22:33:24 < zyp> took it home, retuned it and tried again, passed fine
2017-11-13T22:33:30 < sync> only if you tune it shitty BrainDamage
2017-11-13T22:33:49 < sync> closed loop O2 control at 14.7 afr will always get you through emissions
2017-11-13T22:34:06 < sync> depending on your catalyst generation you need some oxygen loading strateg
2017-11-13T22:34:12 < sync> y
2017-11-13T22:34:35 < zyp> PaulFertser, in what sense?
2017-11-13T22:35:09 < zyp> wire it up, change some config stuff, hope it works, tune it until you get tired of it

2017-11-13T22:37:26 < PaulFertser> I wonder if it's possible to enable hill descent system for modules that have it disabled :)
2017-11-13T22:37:50 < sync> oh, hill descent
2017-11-13T22:37:52 < sync> probably.
2017-11-13T22:38:08 < PaulFertser> sync: 9th generation probably
2017-11-13T22:38:43 < sync> yeah I had not much luck with that recent stuff
2017-11-13T22:38:56 < sync> but older firmwarez are to be had in the bmw sp-daten
2017-11-13T22:39:23 < sync> I did develop a standalone pressure controller using an esp hydroblock a while back thp
2017-11-13T22:39:26 < BrainDamage> we need MPPT ecu
2017-11-13T22:39:34 < englishman> PaulFertser: i built two cars with megasquirt, back when it was new and interesting
2017-11-13T22:39:37 < englishman> works
2017-11-13T22:40:14 < englishman> it was probably the best $100 ecm, a decade ago
2017-11-13T22:41:01 < zyp> yeah
2017-11-13T22:41:03 < englishman> that's pretty cool zyp, what car
2017-11-13T22:41:10 < zyp> volvo 240
2017-11-13T22:41:13 < englishman> cool
2017-11-13T22:41:19 < englishman> you replaced that with egolf?
2017-11-13T22:41:24 < zyp> yeah
2017-11-13T22:41:24 < englishman> or was it earlier
2017-11-13T22:41:35 < zyp> no, I had it until last year
2017-11-13T22:41:42 < englishman> interesting
2017-11-13T22:41:50 < karlp> aandrew: that kemet capacitor video was awesome, thanks. super interesting.
2017-11-13T22:41:51 < englishman> i dailied that car too

2017-11-13T22:41:58 < zyp> same
2017-11-13T22:42:20 < zyp> sync, yeah, I kinda miss the RWD on snowy roads
2017-11-13T22:42:38 < sync> get a winter beater 240
2017-11-13T22:42:43 < sync> and weld the diff
2017-11-13T22:43:16 < zyp> maybe when I have space to keep a bunch of shit
2017-11-13T22:43:21 < BrainDamage> man, i wish i had a 4wd, there are some fucking sweet rally tracks here
2017-11-13T22:44:00 < BrainDamage> doing slideskids with a fwd is a fucking chore
2017-11-13T22:44:24 < zyp> then again, I got rid of the 240 because I didn't want the costs involved in keeping it :p

2017-11-13T22:47:58 < englishman> aww
2017-11-13T22:48:24 < zyp> inspection were due too, and I didn't want to drop any money on repairs to make it pass either
2017-11-13T22:49:46 < englishman> yeah if you don't have the space to store it for 20 years and then give it to your kids, :(
2017-11-13T22:49:59 < zyp> haha
2017-11-13T22:50:38 < zyp> I got it from my parents when they replaced it, I think there's a limit on how many generations a car can be passed down :p
2017-11-13T22:52:43 < vampi-the-frog> Volkswanken
2017-11-13T22:56:13 < vampi-the-frog> I hate cars
2017-11-13T22:56:20 < englishman> same
2017-11-13T22:56:24 < vampi-the-frog> there's way too many in my city and people don't have a parking place
2017-11-13T22:56:29 < vampi-the-frog> so all the streets are filled with cars
2017-11-13T22:56:37 < vampi-the-frog> everywhere you look, cars
2017-11-13T22:56:45 < BrainDamage> karlp: it's probably just jamming vastibular (Spelling?) signaling, as in alcohol does jam most neuroal signals, but on the ear-balance signal it gets mistranslated into audible range
2017-11-13T22:56:53 < vampi-the-frog> and I'm convinced that over half the owners don't even need a car
2017-11-13T22:57:13 < vampi-the-frog> vestibular
2017-11-13T22:57:33 < BrainDamage> well, a lot of things aren't needed, yet are used merely for convenience
2017-11-13T22:57:42 < vampi-the-frog> there should be a law saying you can't own a car if you don't have a parking place
2017-11-13T22:58:11 < upgrdman> vampi-the-frog, agreed
2017-11-13T22:58:34 < BrainDamage> the problem is not merely home residence parking
2017-11-13T22:58:43 < BrainDamage> workplace parking is another whole issue here
2017-11-13T22:58:59 < vampi-the-frog> well, the second iteration of the law is that you'd need a slip from your employer saying that you have a parking place
2017-11-13T22:59:01 < BrainDamage> cities here literally had to implement traffic restriction laws because of it
2017-11-13T22:59:10 < upgrdman> esp in so cal. so many ass holes that cant store their vehicle on their property, so they pakr on the street
2017-11-13T22:59:23 < upgrdman> its part of what makes poor neighborhoods so shitty looking.
2017-11-13T22:59:36 < upgrdman> no parking and lots of shit on the street
2017-11-13T23:00:16 < vampi-the-frog> there was an initiative promoting bike use at some point
2017-11-13T23:00:28 < vampi-the-frog> or ride sharing, I forget which it was, but it was meant to reduce car usage
2017-11-13T23:00:39 < vampi-the-frog> I'm not sure what effect that had
2017-11-13T23:00:46 < vampi-the-frog> but we still have very few actual bike lanes
2017-11-13T23:01:03 < BrainDamage> I'm all for bike promotion https://www.dropbox.com/s/amwejcjhoxpc7fd/out3.mkv?dl=1
2017-11-13T23:02:20 < vampi-the-frog> is that your road to work?
2017-11-13T23:02:32 < BrainDamage> no, it's what i do to relax after work
2017-11-13T23:03:00 < englishman> that's pretty quick for a segway
2017-11-13T23:03:25 < BrainDamage> 80km/h inline segay
2017-11-13T23:03:33 < vampi-the-frog> segay
2017-11-13T23:03:57 < BrainDamage> you can even hear the disk brakes overheating

2017-11-13T23:18:50 < kakimir> two hours ago it started copying one sector at time
2017-11-13T23:18:56 < kakimir> from
2017-11-13T23:19:01 < BrainDamage> if it's from, use ddrescue instead

2017-11-13T23:19:20 < kakimir> thanks
2017-11-13T23:19:21 < BrainDamage> because it can keep journal of try attempts, and retry reading multiple times until succeed
2017-11-13T23:19:32 < kakimir> do I start over?
2017-11-13T23:19:48 < kakimir> and is there any tricks.. cool the drive or so?
2017-11-13T23:20:20 < BrainDamage> cooling the drive *may* impact error probability, depending on the fault type
2017-11-13T23:21:14 < kakimir> at first it copied like chunks of data fast
2017-11-13T23:21:29 < BrainDamage> yes, that's the sane portions of disk
2017-11-13T23:21:33 < kakimir> then it slowed down time to time
2017-11-13T23:22:13 < kakimir> then it's completelly stalled now
2017-11-13T23:22:33 < PaulFertser> Steffanx: do you want me to print anything specific with any specific material (I also have plenty of PLA, and 10m of PETG, bronze, hips each)?
2017-11-13T23:22:35 < kakimir> do I effectivelly destroy the disc as I try to read it?
2017-11-13T23:22:46 < kakimir> is ddrescue any faster than dd btw?
2017-11-13T23:23:11 < PaulFertser> kakimir: most probably, yes, you destroy it, a damaged area emits more and more particles as you're trying to read it.
2017-11-13T23:23:36 < BrainDamage> ddrescure can be faster on /sane/ portion of the disk as you can tell it to skip portions of damaged parts of the disk and then retry later
2017-11-13T23:23:54 < PaulFertser> kakimir: ddrescue is way batter than dd for reading damaged disks as it skips unreadable sectors. dd will just slow to zero on bad areas and you're loosing everything after that.
2017-11-13T23:27:20 < sync> BrainDamage: that looks like a nice road to brap up and down on a tuned vespa
2017-11-13T23:28:18 < hesperaux> HI GUISE
2017-11-13T23:29:21 < BrainDamage> sync: it's actually a variant section of a bi-annual rally course it's held here
2017-11-13T23:32:01 < kakimir> how big will the logfile be?
2017-11-13T23:32:24 < BrainDamage> not large unless your disk is a clusterfuck, even then, few MB at most
2017-11-13T23:32:32 < BrainDamage> it will only store bad sector ranges
2017-11-13T23:35:10 < kakimir> okay
2017-11-13T23:35:13 < kakimir> not in gigabytes?
2017-11-13T23:35:19 < hesperaux> PaulFertser, PETG is my friend
2017-11-13T23:35:26 < kakimir> I have linux from usb stick so
2017-11-13T23:37:21 < PaulFertser> hesperaux: does it have any downsides compared to abs apart from the price?
2017-11-13T23:37:54 < hesperaux> PaulFertser, small ones...not anything worth caring about: you have to print it a bit slower
2017-11-13T23:38:50 < hesperaux> PaulFertser, it has no smell, is much stronger than ABS, and layer adhesion and bed adhesion is incredible. I printed something when I first switched to PETG, with just clean glass underneath. I tried to get the part off and ended up cracking my glass bed
2017-11-13T23:39:23 < hesperaux> so I use some hair spray before each print, to REDUCE bed adhesion a little. Absolutely no warping even on 6" square flat plates
2017-11-13T23:39:43 < hesperaux> as for price, it's only 2 or 3 bucks more than ABS
2017-11-13T23:40:32 < zyp> I'm not super impressed by PETG adhesion, I still have corners curling up :p
2017-11-13T23:40:32 < hesperaux> I have used about 15m or so of 3mm dark blue PETG from eSUN and have been very impressed. Seems very solid and consistent
2017-11-13T23:40:43 < hesperaux> zyp, interesting. You're probably not printing at the right temp
2017-11-13T23:40:45 < zyp> but I don't have a heatbed either
2017-11-13T23:40:50 < hesperaux> oh that's why
2017-11-13T23:41:23 < hesperaux> heatbed makes a huge difference. I run mine at about 80C for PETG and I run the hotend at 250-255C
2017-11-13T23:41:33 < PaulFertser> hesperaux: we have local good quality abs for 6.6 EUR / kg.
2017-11-13T23:41:36 < hesperaux> PaulFertser, one more down side there...have to print slightly hotter
2017-11-13T23:41:40 < zyp> I have hotend at 240
2017-11-13T23:41:47 < hesperaux> PaulFertser, that's dirt cheap
2017-11-13T23:42:12 < hesperaux> zyp, you'll have to print slower at 240 but that might help in your case without the heated bed
2017-11-13T23:42:27 < hesperaux> zyp, do you print with a brim?
2017-11-13T23:42:41 < zyp> I've tried that, didn't seem to help
2017-11-13T23:42:42 < ohsix> 1000jpy is 9.11 usd rn
2017-11-13T23:42:59 < hesperaux> I had major warping annoyances with ABS and printing with a 5-10mm brim helped a lot (didn't completely remove the problem)
2017-11-13T23:43:13 < hesperaux> zyp, also maybe printing your first layer at 255C, then go down to 240, along with the brim
2017-11-13T23:44:07 < hesperaux> PaulFertser, hard to justify the cost of PETG to you at that price for ABS. But not having cancer is pretty nice
2017-11-13T23:44:32 < hesperaux> from what I could find on particulate studies, PETG has the least of the popular filaments
2017-11-13T23:44:38 < englishman> https://i.imgur.com/8RWIa24.png
2017-11-13T23:44:41 < hesperaux> not many studies exist though
2017-11-13T23:44:59 < hesperaux> englishman, this picture is depressing
2017-11-13T23:45:11 < hesperaux> 50G. lol. Cool story bro
2017-11-13T23:45:38 < PaulFertser> hesperaux: petg is 20 EUR / kg (from another local factory)
2017-11-13T23:45:46 < zyp> I haven't tried ABS, but for me it's easy to justify PETG over PLA
2017-11-13T23:45:52 < zyp> I don't like the brittleness of PLA
2017-11-13T23:46:03 < kakimir> letting dd to run on broken drive for 5hours
2017-11-13T23:46:03 < hesperaux> never tried PLA. I have a spool but never actually unwrapped it
2017-11-13T23:46:16 < kakimir> I fucked it up didn't I?
2017-11-13T23:46:18 < englishman> PLA is early 3dicking tech really

2017-11-13T23:46:47 < englishman> speaking of which
2017-11-13T23:46:49 < hesperaux> kakimir, you can mount the bin file you have and see what can be got. In the mean time, I'd switch to using ddrescue and see what happens
2017-11-13T23:46:57 < englishman> scrotal_b_: can you link the amazon weed wacker filamant
2017-11-13T23:47:03 < PaulFertser> kakimir: probably so, but still worth a retry with ddrescue
2017-11-13T23:47:05 < BrainDamage> kakimir: not necessarily
2017-11-13T23:47:17 < BrainDamage> but again, use ddrescue
2017-11-13T23:47:31 < hesperaux> it sounds like you probably have a valid partition table and filesystem (unless you have multiple partitions spread across the disk)
2017-11-13T23:47:59 < kakimir> partition table is okay
2017-11-13T23:48:03 < kakimir> filesystem is fucked
2017-11-13T23:48:11 < hesperaux> hmm
2017-11-13T23:48:14 < kakimir> I did see once file browser to open
2017-11-13T23:48:30 < kakimir> and then it went away 5sec later
2017-11-13T23:48:36 < hesperaux> I was talking about the filesystem in the bin file you dd'd
2017-11-13T23:49:17 < hesperaux> what I would do is keep the dd'd bin, create a second one with ddrescue. Later on, copy the ddrescue bin to a backup and then mount the bin as a loop device and do an fsck
2017-11-13T23:50:07 < hesperaux> and you can do the same thing for the dd'd bin to see if you can get more out of it
2017-11-13T23:50:19 < hesperaux> what FS is this?
2017-11-13T23:50:59 < kakimir> ntfs
2017-11-13T23:51:04 < hesperaux> >_>
2017-11-13T23:51:12 < kakimir> ddrescue seems to be doing grate jobb
2017-11-13T23:51:18 < kakimir> it's not stalling
2017-11-13T23:51:29 < kakimir> rescued data amount is looking good also
2017-11-13T23:51:30 < hesperaux> so in your case, you would I have no idea because it's NTFS
2017-11-13T23:51:42 < hesperaux> can you run a chkdsk program from linux? :/

2017-11-14T00:14:59 < kakimir> oh
2017-11-14T00:15:05 < kakimir> it got over it
2017-11-14T00:16:30 < Ultrasauce> it goes slow because it tries multiple times when things fail, instead of just hanging and then shitting the bed
2017-11-14T00:18:41 < upgrdman> is there any reason why ethernet PHYs are *not* usually integrated into the mcu?
2017-11-14T00:19:21 < sync> probably cost and power reasons
2017-11-14T00:19:36 < sync> and possibly size issues
2017-11-14T00:19:36 < upgrdman> phy's are high power?
2017-11-14T00:19:47 < sync> well, they are linedrivers basically
2017-11-14T00:19:59 < sync> pushing and pulling on the transformer
2017-11-14T00:20:35 < kakimir> I go with -r1 at first as recommended
2017-11-14T00:33:25 < upgrdman> any car pros in here? if i want tires that have a little better traction, how do i find them?
2017-11-14T00:33:40 < sync> what do you have now?
2017-11-14T00:33:45 < upgrdman> like is the rubber compound part of the model #, or do i just have to read reviews and hope theres not too many idiots
2017-11-14T00:33:46 < sync> and when do you want more traction?
2017-11-14T00:34:00 < upgrdman> sync, more traction during breaking and turning
2017-11-14T00:34:13 < upgrdman> and i have Barum
2017-11-14T00:34:13 < upgrdman> Brillantis 2
2017-11-14T00:34:13 < upgrdman> 195 /60 R15 88H SL BSW
2017-11-14T00:34:22 < sync> there is the error
2017-11-14T00:34:31 < upgrdman> ya, cheap shit, huh?
2017-11-14T00:34:36 < sync> barum is conti but cheapshit
2017-11-14T00:34:42 < upgrdman> conti?
2017-11-14T00:34:47 < sync> continental
2017-11-14T00:35:53 < sync> conti premiumcontact 5 has been ok for regular use
2017-11-14T00:36:51 < kakimir> are you looking for summer tyres?
2017-11-14T00:36:59 < kakimir> winter tyres?
2017-11-14T00:37:00 < sync> he is in cali
2017-11-14T00:37:03 < sync> so basically no winter
2017-11-14T00:37:22 < kakimir> upgrdman is cali man?
2017-11-14T00:37:24 < kakimir> cool
2017-11-14T00:37:27 < upgrdman> yes
2017-11-14T00:37:42 < sync> yokohama advan neova ad08 has also been good for me
2017-11-14T00:37:52 < kakimir> I have continental premiumcontact 5 set for summer
2017-11-14T00:37:57 < upgrdman> and yes, winter == put a thin jacket over my t-shirt
2017-11-14T00:39:05 < upgrdman> hmm at the shop i go to, they have lots of cheap shit tires in stock, and the only "name brand" ones they have in stock are some Falken Pro G4 A/S which is 200% the price
2017-11-14T00:39:05 < sync> if you want wtf is that size
2017-11-14T00:39:29 < sync> yes, expect to pay more than you are used to
2017-11-14T00:39:38 < upgrdman> barums are ~$50 each
2017-11-14T00:39:51 < upgrdman> i guess i should stop being a cheap jew
2017-11-14T00:40:00 < upgrdman> whats reasonable? $90 each?
2017-11-14T00:40:31 < sync> idk, the contis are like 60€ here
2017-11-14T00:40:34 < sync> and they are ok tires
2017-11-14T00:40:48 < sync> ad08-r runn ~140€
2017-11-14T00:40:55 < upgrdman> damn
2017-11-14T00:40:58 < sync> direzza 03G 225€
2017-11-14T00:41:20 < sync> but those are high performance tires
2017-11-14T00:41:49 < upgrdman> i mainly want better breaking. for some retarded reason my 2005 car does NOT have abs
2017-11-14T00:41:59 < upgrdman> i didnt even know cars were still sold without abs
2017-11-14T00:42:00 < upgrdman> lol
2017-11-14T00:42:18 < sync> your braking distance is not going to go down with abs
2017-11-14T00:42:29 < upgrdman> orly?
2017-11-14T00:42:33 < sync> yarly
2017-11-14T00:42:37 < ohsix> sup
2017-11-14T00:43:23 < sync> modern abs will be very close to the optimum slip ratio but that is all your tire is going to give you
2017-11-14T00:43:41 < sync> you cannot exceed the circle of forces with it
2017-11-14T00:44:02 < sync> learn how to threshold brake
2017-11-14T00:44:22 < sync> and replace those asphalt cutting disks with something good
2017-11-14T00:45:17 < ohsix> you can look on the side wall for the rubber composition
2017-11-14T00:45:33 < ohsix> the 'better grip' ones that are soft for winter driving has their own snowflake marks
2017-11-14T00:45:41 < PaulFertser> sync: probably his distance will go down if upgrdman is used to break by skidding :)
2017-11-14T00:45:53 < upgrdman> lol
2017-11-14T00:46:17 < sync> ohsix: "soft" compounds will be out of their working range in upgrdman-weather
2017-11-14T00:46:28 < upgrdman> sync, yes i learned long ago about how to threshold break
2017-11-14T00:46:53 < upgrdman> but it still sucks not having abs. i actually have to think when i brake hard. i have to THINK. the horror.
2017-11-14T00:46:56 < sync> brake
2017-11-14T00:46:58 < sync> :D
2017-11-14T00:47:11 < upgrdman> ya fuck me. brake*
2017-11-14T00:47:21 < sync> well, get a car with abs then
2017-11-14T00:47:33 < PaulFertser> upgrdman: imagine a motorbike that lacks abs then. Block the front wheel for a second (or much less if you're in a turn) -> fall.
2017-11-14T00:47:55 < upgrdman> yes
2017-11-14T00:48:02 < englishman> what 2005 car doesnt have abs?
2017-11-14T00:48:07 < upgrdman> sync, thats planned
2017-11-14T00:48:07 < PaulFertser> A US one :)
2017-11-14T00:48:16 < upgrdman> englishman, inorite. 2005 toyota celica gt.
2017-11-14T00:48:35 < upgrdman> abs was optional, and back then i didnt know shit and didnt think to get it.
2017-11-14T00:49:04 < englishman> pad and rotor upgrade might be in order if you want better braking
2017-11-14T00:49:06 < PaulFertser> upgrdman: on a car, can't you just lock the wheels then depress a bit?
2017-11-14T00:49:17 < englishman> or are you locking up
2017-11-14T00:49:23 < sync> can you actually lock the brakes or are you traction limited?
2017-11-14T00:49:33 < sync> like the golf was when the brakes got hot
2017-11-14T00:49:33 < upgrdman> no i can lock both front wheels
2017-11-14T00:49:36 < upgrdman> if i try
2017-11-14T00:49:39 < englishman> maybe leave a little more room between you and the car in front of you
2017-11-14T00:49:52 < sync> are your tire pressures reasonable?
2017-11-14T00:49:54 < ohsix> just having your brakes inspected to see if a cylinder is blown out can double your braking perf, olol (my car, few months ago)
2017-11-14T00:50:03 < upgrdman> englishman, hey hey hey. i drive like an asshole, and as an american, that's my right.
2017-11-14T00:50:09 < upgrdman> sync, yes
2017-11-14T00:50:18 < upgrdman> i can brake fine.
2017-11-14T00:50:23 < upgrdman> its just that it could be better.
2017-11-14T00:50:33 < upgrdman> it was much better on the original tires.
2017-11-14T00:50:37 < sync> http://sync-hv.de/~tmp/eeeeee.mp4 it was interesting to see how the sidewall flexes
2017-11-14T00:50:39 < sync> yeah
2017-11-14T00:50:40 < upgrdman> so these shit berums are shit
2017-11-14T00:50:41 < sync> get nonshit tires
2017-11-14T00:50:44 < upgrdman> yes
2017-11-14T00:50:52 < upgrdman> THATS WHY IM ASKING IN HERE :)
2017-11-14T00:51:03 < ohsix> abs application is proportional and newer cars will detect slip with the same sensors, so it may not even matter for most of the driving you do; and you can just avoid the worst-case
2017-11-14T00:51:41 < ohsix> you slip on naked pavement too, if you're doing xxxxxxxtreme braking that will have abs leaving chirp marks
2017-11-14T00:51:59 < englishman> here get these
2017-11-14T00:52:00 < englishman> https://shop.hoosiertire.com/index.php/circuit-racing/22-0x-8-0-13-r35a-a2500.html
2017-11-14T00:52:02 < sync> ohsix: it was always like that. just the newest hydroblocks are capable of modulating the pressure by using the valves in position mode
2017-11-14T00:52:03 < upgrdman> yay for chirp marks
2017-11-14T00:52:08 < englishman> just make sure you get them warm
2017-11-14T00:52:17 < upgrdman> englishman, lol
2017-11-14T00:52:27 < upgrdman> is hankook decent?
2017-11-14T00:52:33 < upgrdman> they $5 more than my shit barums
2017-11-14T00:52:40 < englishman> all mfgrs make cheap shitty tires
2017-11-14T00:52:42 < sync> depends on the tire
2017-11-14T00:52:44 < sync> yeah
2017-11-14T00:52:55 < upgrdman> Hankook
2017-11-14T00:52:55 < upgrdman> Optimo H724

2017-11-14T00:53:01 < sync> just get the premiumcontacts and be fine
2017-11-14T00:53:04 < ohsix> if you want to actually know, find out the compositions and compare them; their business is obfuscating the benefit of the not-baseline tires
2017-11-14T00:53:06 < sync> they are a good tire
2017-11-14T00:53:32 < ohsix> i wouldn't be surprised if SAE just said what types of tire compositions were road legal
2017-11-14T00:54:47 < ohsix> http://topics.sae.org/tires-and-traction/standards/ wish i had time to look at 612 standards relating to tires and traction
2017-11-14T00:56:09 < ohsix> 3d pritner failed in a fun way and it's given me a break from it, but it's funny to talk about it with people who are supposed to know electronics
2017-11-14T00:56:33 < ohsix> the resistance in the connector was high enough to melt the connector and they're misattributing that as the defect
2017-11-14T00:56:48 < ohsix> the connector is beefy af and fails safe compared to any other component in there
2017-11-14T00:56:58 < scrotal_b> Hi
2017-11-14T00:57:27 < ohsix> there would have been a fire if the connector was rated higher just to handle that worst-case contact resistance
2017-11-14T00:58:12 < upgrdman> ohsix, using a connector as a FUSE sounds kinda fucked
2017-11-14T00:58:35 < ohsix> it wasn't something that could be fused
2017-11-14T00:59:06 < ohsix> the connector got hot in preference to anything else due to the way it was assebmled & how the cabling was done, when the thing it was hooked to had a 100% duty cycle for hours
2017-11-14T00:59:19 < ohsix> which doesn't happen in normal use, and only happens when the thermistor fails
2017-11-14T01:00:20 < upgrdman> typical 3d printer, designed by non-engineers. do they even redundancy bro.
2017-11-14T01:00:30 < upgrdman> if one failure can lead to a fire...
2017-11-14T01:00:30 < ohsix> the software may be able to try and be clever by tracking duty cycle and keeping track of the wire diameters and shit, but that's almost always going to be wrong with people fucking around with their own
2017-11-14T01:00:37 < ohsix> it can't in this printer
2017-11-14T01:00:44 < ohsix> that's the entire pointttttttttttt
2017-11-14T01:05:21 < ohsix> you can argue lots of shit should have been done with the failure in mind and stuff but disregarding a design decision that was intended in the case of failure is dumb
2017-11-14T01:05:52 < ohsix> if you measured the connector housing temperature or something, that thermistor can fail too; and you're just adding another failure point
2017-11-14T01:06:28 < upgrdman> ohsix, seems pretty dumb to me to DESIGN a connector that will knowingly get hot in normal use.
2017-11-14T01:07:24 < upgrdman> current monitoring + a little math = problem solved
2017-11-14T01:07:42 < upgrdman> of course that'd increase the BoM cost by $1 so no one would buy it then
2017-11-14T01:09:10 < upgrdman> im kinda surprised someone house has not burnt down, leading to a 3d printer lawsuit
2017-11-14T01:09:21 < upgrdman> considering how shit a lot of the controllers are
2017-11-14T01:10:26 < ohsix> upgrdman: it's not normal use
2017-11-14T01:10:36 < ohsix> and current monitoring isn't going to tell you anything
2017-11-14T01:10:57 < ohsix> you are driving the heater
2017-11-14T01:11:06 < ohsix> it only becomes a problem when it does it for 10 hours
2017-11-14T01:12:04 < upgrdman> yes. and for a give booty cycle, there should be a corresponding current. if its off by x%, theres a problem. and you can also integrate that to get an estimate of the energy dumped into the bed so it doesnt burn if you drive it at 100% for hours
2017-11-14T01:12:13 < ohsix> worst case scenario is assumed ruining the build plate or the heater under it
2017-11-14T01:12:24 < ohsix> .
2017-11-14T01:13:08 < ohsix> the duty cycle being 100% sometimes, even for long stretches of time, isn't wrong
2017-11-14T01:13:10 < ohsix> or an error
2017-11-14T01:13:33 < ohsix> you start harming the performance of the thing in the name of a slightly tangible safety benefit
2017-11-14T01:13:51 < upgrdman> no fire == slightly tangible? good to know.
2017-11-14T01:14:09 < ohsix> you're also missing that there is no fire because of the connector failing in preference to everything else
2017-11-14T01:14:14 < ohsix> that's why this is maddening
2017-11-14T01:14:23 < ohsix> even when i tell you what is happening you missed it :p
2017-11-14T01:14:37 < upgrdman> ya i get that, but it seems like a dirty hack.
2017-11-14T01:14:41 < ohsix> not even the smoke came out of the connector
2017-11-14T01:14:53 < ohsix> the plastics and shit in the connector constrained the damage
2017-11-14T01:15:15 < upgrdman> unless that connector manuf's specifically designed it to perform like that, relying on a connector to melt is bad.
2017-11-14T01:15:17 < ohsix> there is a current sense for the other wires failing
2017-11-14T01:15:42 < ohsix> it didn't melt, and connectors have spefications in the plastics for flammability
2017-11-14T01:15:54 < ohsix> it turns into a foam
2017-11-14T01:16:48 < ohsix> well, i guess as part of doing that it technically melted a little; has to expand when offgassing
2017-11-14T01:17:28 < ohsix> you'd still prefer the connector to fail than any of the expensive parts, like the controller or controller driver
2017-11-14T01:18:02 < ohsix> you overbuild all the things but the connector, the connector is rated for average use & flammability shit; it fails first, that's not too different from what a fuse does
2017-11-14T01:18:56 < ohsix> people see this type of failure in shit they're using and they put a bigger connector onto it
2017-11-14T01:19:17 < ohsix> they don't even consider that they're moving the 'fuse' around
2017-11-14T01:19:58 < ohsix> it's not just 3d printers either; there's a larger point about how people don't know any better do things ;]
2017-11-14T01:20:06 < ohsix> people put paperclips in fuse holders and shit
2017-11-14T01:20:53 < englishman> www.digikey.ca’s server DNS address could not be found.
2017-11-14T01:20:54 < englishman> wtf
2017-11-14T01:20:58 < englishman> this is happening a lot today
2017-11-14T01:21:10 < ohsix> people can't think very well about stuff that is designed to fail, it's almost like a fixation
2017-11-14T01:21:40 < ohsix> think about those bolts at the bottom of road signs, they're designed to snap so the sign doesn't fucking kill you when you hit it, huhuhu
2017-11-14T01:22:06 < ohsix> people get annoyed that a sign keeps falling down, they reinforce it every time they put it back up; someone dies
2017-11-14T01:22:21 < Ultrasauce> maybe dont crash into signs

2017-11-14T01:24:30 < ohsix> that's also moving the problem from where it actually is
2017-11-14T01:24:35 < ohsix> driving a car is not safe
2017-11-14T01:24:52 < ohsix> even someone who is awesome and drives well will hit a sign
2017-11-14T01:24:58 < Ultrasauce> you know there's such a thing as a thermal fuse right?
2017-11-14T01:25:02 < ohsix> the only way to not have that risk is for the same person not to drive
2017-11-14T01:25:11 < ohsix> yes
2017-11-14T01:25:29 < ohsix> but those need to be near to or attached to a mass that actually heats enough to trigger it
2017-11-14T01:25:31 < Ultrasauce> so why is relying on the failure of the connector to serve that purpose ok in your books
2017-11-14T01:25:49 < Ultrasauce> like, say, the print bed?
2017-11-14T01:26:15 < ohsix> if the print bed failed the same way that led to this connector it'd be expensive and cause a lot of smoke
2017-11-14T01:26:31 < ohsix> the print bed can do 10 hours at 100% duty cycle
2017-11-14T01:26:47 < Ultrasauce> the point is to keep it from doing that....
2017-11-14T01:27:07 < Ultrasauce> ugh why am I even doing this
2017-11-14T01:27:11 < ohsix> are you forgetting what can happen to the thermistor
2017-11-14T01:27:30 < ohsix> 3d print jobs can run for days
2017-11-14T01:27:37 < englishman> all fuses are thermal fuses

2017-11-14T01:44:11 < PaulFertser> ohsix: marlin and repetier 3d printer firmwares have fire prevention logic integrated and enabled: if regulator is getting far too unexpected results, it just disconnects the heater altogether.

2017-11-14T01:45:06 < Laurenceb_> No assumption should go unchallenged. We could test the assumption that all modules receive the SOF at the same time by having an output briefly set high when an SOF is received. With multiple modules connected we should see the same GPIO on all modules go high at the same time on an oscilloscope

2017-11-14T08:59:18 < PaulFertser> ohsix: if the temperature doesn't increase more than the setpoint even with 100% duty cycle it means the heater has no headroom at all, the setpoint is far too high. In normal conditions the temperature sensor should be showing changes based on what you do with the heater. And regulator (PID or other type) should certainly be able to detect the case when results are unexpected.
2017-11-14T09:01:20 < qyx> ohsix: modemmanager/networkmanager worked for me out of box even for the china m590 modules (over uart)

2017-11-14T09:27:42 < zyp> I've talked about mqtt, but I don't really have much experience with libs, I've only used hbmqtt
2017-11-14T09:30:23 < ohsix> PaulFertser: the feedback through the thermistor is all that really says what the duty cycle is
2017-11-14T09:30:36 < ohsix> qyx: cool
2017-11-14T09:31:12 < PaulFertser> ohsix: hm, I assumed the duty cycle is not feedback, it's actually the control signal that board outputs to a FET connected to a heater.
2017-11-14T09:31:17 < ohsix> is that Network shenanigans part of how you implement the host side of some embedded junk?
2017-11-14T09:31:45 < ohsix> PaulFertser: the duty cycle is an artifact of the implementation, the set point is a temperature, the thermistor a temperature sensor
2017-11-14T09:32:01 < qyx> wolfmqtt looks better
2017-11-14T09:33:19 < PaulFertser> ohsix: ok, and I'm saying that if the regulator is turning the heater ON for, say, 5 consequitive minutes and the temperature sensor doesn't show a rise, then it's safe to assume something is wrong and disable the heater altogether.
2017-11-14T09:36:40 < ohsix> that depends on the setpoint, that's probably true / a good rule of thumb for a known physical configuration when all your ducks are in a row
2017-11-14T09:38:37 < ohsix> it would probably have to be longer than 5 minutes, if you're operating right on the edge and 100% actually happens occasionally, things like central air coming on are going to change operation of the shit on tha torder of time
2017-11-14T09:39:02 < ohsix> you can't mess with the actual printing unless there's literally a fire imminent huhuh
2017-11-14T09:41:57 < PaulFertser> ohsix: well, that's my point, you shouldn't be operating right on the edge in the first place. Then this logic would just work and chances of fire would be minimised.
2017-11-14T09:42:27 < ohsix> it's not a contrived situation, control system stuff kind of works on assurances that parts won't be likely to fail, like the sensors
2017-11-14T09:43:29 < ohsix> PaulFertser: why 5 minutes? being 'overbuilt' and my guess at 10 hours is a lot less intrusive

2017-11-14T09:46:16 < PaulFertser> ohsix: less intrusive but less safe also. For repetier fw default decouple test time is 20 seconds for extruder heater, 300 seconds for bed. If temperature doesn't rise 0.1C, too bad, the print should be stopped. Better be safe than sorry.
2017-11-14T09:46:59 < jpa-> thermal fuses seems like the obvious solution
2017-11-14T09:47:24 < jpa-> and instead of hard stop, just pause the print so that it can be continued without problems if it was a false alarm
2017-11-14T09:48:13 < PaulFertser> How would a thermal fuse detect if my heater would slip off from the heater block?
2017-11-14T09:48:29 < jpa-> true
2017-11-14T09:48:53 < ohsix> PaulFertser: the thermistor can fail in a way that the temperature change correlates with a reading change, but it is not the actual temperature
2017-11-14T09:49:07 < PaulFertser> That's why it's called "decoupling" detection. Tries to detect when thermistor is thermally decoupled from heater.
2017-11-14T09:49:10 < ohsix> and the thermistor can be working fine, but the connection can be failing
2017-11-14T09:49:35 < ohsix> either way you get feedback that keeps the process going
2017-11-14T09:50:04 < ohsix> thermal fuse would be a great idea if there was a place to put one
2017-11-14T09:50:17 < ohsix> it doubles as an obvious safety device
2017-11-14T09:50:42 < ohsix> hm
2017-11-14T09:50:50 < PaulFertser> So, what popular firmware doesn't have decouple detection?
2017-11-14T09:50:54 < ohsix> it's not easy to put one on the lulzbot
2017-11-14T09:51:36 < ohsix> PaulFertser: the problem is that all the failure modes aren't accounted for by being clever
2017-11-14T09:52:21 < PaulFertser> ohsix: true, it's all about the overall statistics.
2017-11-14T09:52:25 < ohsix> if we're being proscriptive and tutting about what people should do, we could also just say don't use a heated bed, not worth the risk

2017-11-14T09:54:34 < ohsix> did you see the vice principals finale?
2017-11-14T09:55:05 < ohsix> they're smart to realize they couldn't do shit for 8 years, and that 2 was maybe even a stretch
2017-11-14T09:55:18 < ReadErr> nah im gonna watch it all the way through
2017-11-14T09:55:46 < jpa-> looks like smoothieware does that check "temperature differs from target by N celcius for more than T seconds".. not quite as fast as PaulFertser mentioned but should work
2017-11-14T09:57:38 < jpa-> it's kind of surprising that there aren't more 3d printers designed for fire safety, something like metal box with a cutoff if the box reaches too high temperature should work pretty well
2017-11-14T09:58:14 < ohsix> you could try to electrically characterize the thermistor circuit in a way not affected by poor or intermittent connections, or definitive when it is open
2017-11-14T09:58:30 < ohsix> well, there's not much risk, for all the chat
2017-11-14T09:58:52 < ohsix> something has to be grossly fucked up, and use wire or materials that aren't fire retardant; there's just not enough material there
2017-11-14T09:59:14 < ohsix> hot end failures can make the filament do some gross stuff tho
2017-11-14T09:59:34 < jpa-> considering how the typical workbench looks, there might be quite enough material nearby
2017-11-14T09:59:47 < ohsix> yea
2017-11-14T10:00:06 < ohsix> they're pretty wide, it is almost hard to hang paper or drapes or something fire friendly over them :D
2017-11-14T10:04:30 < ohsix> and if you're talking about a lab, there's all those 895d or whatever clones that will catch fire if you're nto careful with how you put the hot air gun on them
2017-11-14T10:04:35 < ohsix> and will anyways even if you are
2017-11-14T10:06:59 < jpa-> you don't leave those running for hours unattended though.. while the temptation to do so with 3d printers is quite large
2017-11-14T10:10:10 < ohsix> yea but the risk is there any time the switch in the back is on, not the switches in the front
2017-11-14T10:10:18 < ohsix> they look like they're off

2017-11-14T10:13:11 < ohsix> ya i think that's just the hot air portion of these things in its' own box
2017-11-14T10:14:44 < ohsix> more of a joke than anything else, assuming everyone has seen that video of one catching fire
2017-11-14T10:19:37 < ohsix> the difficulty i'm having finding the video i'm talking about is some pretty definitive proof that google is fucking shit now

2017-11-14T15:41:05 < kakimir> can I use recovery usb media created in any windows 7 machine to fix any win7 so it boots?
2017-11-14T15:41:37 < kakimir> lets assume both are x64
2017-11-14T15:42:19 < Laurenceb_> ok some actual content
2017-11-14T15:42:29 < Laurenceb_> if Ihave high speed usb -> hub -> low speed
2017-11-14T15:42:41 < Laurenceb_> will the SOF be delayed at the devices?
2017-11-14T15:42:54 < Laurenceb_> and how much? Is there a 1 microframe delay or something?
2017-11-14T15:43:08 < aandrew> IIRC the SOF is for the local "segment" not global
2017-11-14T15:43:25 < aandrew> I'd have to hook up a few hubs with some STM32 devboards emitting SOF and see
2017-11-14T15:43:38 < aandrew> I don't see any advantage to SOF being global though
2017-11-14T15:44:40 < Laurenceb_> according to this the high speed bus doesnt wait
2017-11-14T15:44:42 < Laurenceb_> http://www.usbmadesimple.co.uk/ums_6.htm#high_speed_hubs
2017-11-14T15:44:51 < Laurenceb_> but that doesnt explain what happens to SOF
2017-11-14T15:47:16 < Laurenceb_> should be trivial to send SOF through the hub and change the bitrate tho?

2017-11-14T20:15:02 < Steffanx> except for the blue figure the prints dont look too bad PaulFertser.
2017-11-14T20:15:05 < Steffanx> 0.2mm layer height?
2017-11-14T20:23:35 < upgrdman> with 10/100 ethernet, does a PHY usually *need* to be configured before it can be used, or is that only required for "special" things?
2017-11-14T20:24:02 < upgrdman> DP83848CVVX if that makes any difference
2017-11-14T20:27:40 < Steffanx> Not sure about the default settings, but usually you can make them usable by using boostrapping using the right pullups/downs on certain pins.
2017-11-14T20:28:04 < upgrdman> k
2017-11-14T20:29:04 < Steffanx> but why this question?
2017-11-14T20:29:27 < Steffanx> its not that you have to do a shitload of configuration..
2017-11-14T20:29:42 < upgrdman> first time doing ethernet
2017-11-14T20:30:00 < upgrdman> and not sure if i just need to config the lpc1768 periph, or also dick with the phy
2017-11-14T20:30:32 < upgrdman> for now i just hope to see a valid packet with wireshark. but i dont even have the pcb yet, just working on the firmware.
2017-11-14T20:30:39 < upgrdman> should have the board in a week-ish
2017-11-14T20:31:35 < upgrdman> "here's a known good schematic, i'll get you some tested ethernet firmware." then after my pcb goes to fab "oh, lol, we never actually used that ethernet. no firmware. hope the schematic was right? lolumad."
2017-11-14T20:31:38 < Laurenceb> <zyp> Laurenceb, it might make more sense if you distinguish between the TT and the rest of the hub
2017-11-14T20:31:42 < Laurenceb> what is TT?
2017-11-14T20:32:48 < aandrew> upgrdman: most PHYs have sane defaults. the only one you really need to watch is whether it supplies the (R)MII clock or accepts it
2017-11-14T20:33:31 < Laurenceb> oh transaction translator
2017-11-14T20:33:51 < upgrdman> aandrew, oh, good. ok.
2017-11-14T20:34:37 < Laurenceb> ooh nice
2017-11-14T20:34:52 < Laurenceb> with Multi-TT I could have batshit insane numbers of sensors
2017-11-14T20:35:12 < aandrew> I want to find a USB3 hub that actually has multi-TT
2017-11-14T20:35:16 < aandrew> I haven't found one yet
2017-11-14T20:35:22 < Laurenceb> only limited by number of devices on the bus
2017-11-14T20:35:37 < aandrew> that way I can plug a half dozen USB2HS devices into a USB3 hub and actually get full performance on all of them
2017-11-14T20:36:18 < Laurenceb> this looks relevant http://www.microchip.com/forums/m329799-p2.aspx
2017-11-14T20:36:21 < aandrew> all chips/hubs I've looked at do not; USB2.0 traffic goes over the single D+/D- pair and all USB3 traffic goes over the HS pairs
2017-11-14T20:36:24 < aandrew> er SS pairs
2017-11-14T20:37:26 < aandrew> I wonder if you can't just use a PLL fed off of the SOF tick and nudge the output of the PLLs over so they're in sync
2017-11-14T20:38:01 < Laurenceb> thats kind of what I am doing
2017-11-14T20:38:27 < Laurenceb> but wurk email is raging about possible lag between devices
2017-11-14T20:38:58 < Laurenceb> oh wow
2017-11-14T20:39:04 < Laurenceb> Leo is in the thread
2017-11-14T20:44:46 < Laurenceb> >USB is a highly fault tolerant consumer grade interface and devices must therefore tolerate several consecutive missed SOF packets according to the standard
2017-11-14T20:44:51 < Laurenceb> lul I'm screwed
2017-11-14T20:44:58 < Laurenceb> never seen that so far though
2017-11-14T20:46:23 < aandrew> interesting, IEEE1588 isn't limited to ethernet

2017-11-14T20:46:48 < aandrew> you could also maybe try doing clock sync similar to how nordic chips do it. google for nrf51822 clock sync, nordic has a paper on it with measurements
2017-11-14T20:46:57 < Laurenceb> ok
2017-11-14T20:47:07 < Laurenceb> >A TT must generate a full-speed SOF within +/- 3 full-speed bit times from the occurrence of the zeroth high-speed SOF.
2017-11-14T20:47:13 < Laurenceb> looks like no issue there then
2017-11-14T20:48:25 < Laurenceb> the nordic thing looks like F042 usb clock
2017-11-14T20:49:24 < Laurenceb> if usb SOF is +-500ppm thats good enough for me
2017-11-14T20:49:51 < Laurenceb> although synchronising with audio devices could get "interesting"
2017-11-14T20:52:30 < Laurenceb> oh - unless I build my own audio kit
2017-11-14T21:02:56 < Laurenceb> surely someone has built lunix tools for solving this problem

2017-11-14T22:32:18 < Steffanx> PaulFertser, it always goes from home position to hte middle of the bed, while it does that it draws a tiny line. So far so good, then it starts to move around a bit while it does not extrude the filement. And then it does.. but it seem its not fast enough so it starts to drag the stuff around a bit.
2017-11-14T22:32:32 < Steffanx> *filament
2017-11-14T22:34:04 < Steffanx> Welcome.
2017-11-14T22:35:05 < PaulFertser> Steffanx: I have http://paste.debian.net/995777/ in the start gcode so that it extrudes a bit and then wipes it off by the front of the bed. And then I usually enable skirt so even if it underextrudes it a bit, no problem.
2017-11-14T22:36:16 < Steffanx> PaulFertser: that's what i/it does too, but the moving while not extruding after that seems to screw things up ( sometimes )
2017-11-14T22:37:01 < PaulFertser> Steffanx: how moving without extruding affects anything if it tries to print a skirt during that?
2017-11-14T22:37:11 < Steffanx> For now i do a skirt too and just try to remove the crap with a tweezer before it starts the actual printing.
2017-11-14T22:38:04 < Steffanx> actually not a skirt, but a brim
2017-11-14T22:38:19 < Steffanx> works for now, until i figure out why it does what it does currently.

2017-11-15T00:10:54 < jadew> could be, they're usually very small

2017-11-15T00:13:19 < Cracki> I've seen "DRM chips" for disposable hardware that had nothing on them, except some transistor-looking things

2017-11-15T00:25:35 < Cracki> and perhaps also the power stage for the arm
2017-11-15T00:26:50 < Cracki> the longish one with two rows of legs is sdram
2017-11-15T00:27:08 < Cracki> why did you hunt for eeprom again?
2017-11-15T00:28:11 < Cracki> the APL1117 and its neighbor are both LDOs
2017-11-15T00:30:39 < kakimir> calibration data
2017-11-15T00:30:54 < kakimir> jadew: totally empty back
2017-11-15T00:31:33 < jadew> then it's probably programmed in one of those big ICs
2017-11-15T00:31:55 < Cracki> calibration data? on a HDD?
2017-11-15T00:31:59 < Cracki> I don't think so.
2017-11-15T00:32:06 < Cracki> it prolly self-calibrated
2017-11-15T00:32:09 < jadew> where else would it be?
2017-11-15T00:32:21 < Cracki> what's there to calibrate?
2017-11-15T00:32:37 < jadew> magnetic strength or whatever.. I don't know
2017-11-15T00:32:45 < jadew> but the ones I dealt with had an eeprom
2017-11-15T00:32:49 < Cracki> I doubt that varies
2017-11-15T00:32:50 < jadew> and you had to move it around
2017-11-15T00:33:38 < Cracki> defective sectors table? not sure eeprom is enough for that
2017-11-15T00:33:57 < jadew> no, it needed that to start reading more
2017-11-15T00:34:07 < jadew> it's like the boot sector on a disk
2017-11-15T00:34:22 < jadew> tiny bit of info so it can read the rest of the info it needs to function
2017-11-15T00:34:42 < Cracki> transplanting PCBs is possible, if it's not a different revision or something, because revisions might change the hardware too
2017-11-15T00:34:46 < Cracki> uh
2017-11-15T00:34:57 < Cracki> firmware is in the big chips
2017-11-15T00:35:11 < Cracki> I still see no point in off-chip eeprom
2017-11-15T00:35:30 < Cracki> something as big as those has on chip flash and most other memory, except the SDRAM
2017-11-15T00:35:36 < jadew> do a google for hdd eeprom
2017-11-15T00:35:51 < jadew> you'll find lots of images indicating where it is
2017-11-15T00:36:32 < Cracki> hm, crypto keys perhaps
2017-11-15T00:36:33 < jadew> yeah, there has to be a reason why that data is usually put in an external eeprom
2017-11-15T00:36:43 < Cracki> or they talk about SPI flash chips
2017-11-15T00:36:46 < jadew> maybe precisely for recovery purposes?
2017-11-15T00:38:26 < Cracki> I only find resources that don't know the difference between eeprom and flash
2017-11-15T00:38:38 < Cracki> (as per common usage)
2017-11-15T00:39:25 < jadew> https://forum.hddguru.com/viewtopic.php?t=22121&start=
2017-11-15T00:39:36 < Cracki> this dude here clearly is dealing with program code, either on-chip flash or off-chip spi flash https://www.malwaretech.com/2015/05/hard-disk-firmware-hacking-part-4.html
2017-11-15T00:40:16 < Cracki> they also talk about "eeprom, eprom, flash"
2017-11-15T00:40:32 < Cracki> so they arent looking for data as such, they are looking for the firmware
2017-11-15T00:40:54 < jadew> doesn't really matter what it is, the point is that there's something that seems to be different from disk to disk
2017-11-15T00:40:59 < Cracki> ...
2017-11-15T00:41:19 < Cracki> and in which way? firmware varies, because it might be newer
2017-11-15T00:41:30 < jadew> no, it could be firmware + some data
2017-11-15T00:41:33 < Cracki> if the drive hw is the same, you can just transplant the whole pcb
2017-11-15T00:41:44 < jadew> doesn't matter if it's a flash chip or an eeprom
2017-11-15T00:41:49 < Cracki> where do you take the information that there must be some extra data?
2017-11-15T00:41:59 < jadew> Cracki, because it doesn't work otherwise
2017-11-15T00:42:11 < Cracki> "doesn't work" can have plenty of reasons
2017-11-15T00:42:22 < Cracki> for example: hardware requires a different firmware
2017-11-15T00:42:23 < jadew> well, the eeprom seems to be the reason
2017-11-15T00:42:32 < Cracki> nvm, not making progress here
2017-11-15T00:42:37 < jadew> could be, but that's unlikely on the same board revision
2017-11-15T00:42:47 < Cracki> ya think?
2017-11-15T00:43:07 < Cracki> if the PCBs are good, but the hardware needed a tweak, just change the firmware and hardware, keep the pcbs...
2017-11-15T00:43:14 < jadew> still, if it requires different firmware, that's something that is different and is stored in some memory
2017-11-15T00:43:23 < Cracki> that's how I experience development of devices
2017-11-15T00:43:24 < jadew> so the memory has to be transplated too
2017-11-15T00:43:46 < Cracki> granted
2017-11-15T00:44:15 < Cracki> those pics are blurry enough to not decipher the trickier components
2017-11-15T00:44:31 < Cracki> and still the firmware could be in the big chips, and was programmed via some header
2017-11-15T00:44:49 < jadew> I don't think it's a matter of firmware
2017-11-15T00:44:51 < Cracki> (as it always is, even for discrete memory chips)
2017-11-15T00:47:22 < jadew> the reason I say that is because the eeproms I've read had very little memory
2017-11-15T00:47:35 < jadew> it was clearly data
2017-11-15T00:47:59 < jadew> and if that data is so important then it must be some sort of calibration data
2017-11-15T00:48:30 < jadew> it's not crypto keys or anything like that either, because this has been the case since people didn't even care about security
2017-11-15T00:52:37 < kakimir> there is thing like integrated eeprom
2017-11-15T00:52:57 < jadew> yeah, that's what I think it's happening there
2017-11-15T00:53:15 < jadew> unless of course they figured out a way to make them work without that extra stuff
2017-11-15T00:53:22 < jadew> like Cracki suggested
2017-11-15T00:53:32 < jadew> in which case you don't have to bother with that
2017-11-15T00:53:40 < jadew> probably a good idea to start reading on the topic
2017-11-15T00:54:16 < Cracki> so what is the task?
2017-11-15T00:54:35 < Cracki> recovering data from a hdd? what's broken, pcb or hardware?
2017-11-15T00:54:59 < jadew> Cracki, you can't tell in this failure mode
2017-11-15T00:55:14 < Cracki> what is the failure mode
2017-11-15T00:55:18 < kakimir> click of death
2017-11-15T00:55:40 < Cracki> how many times
2017-11-15T00:56:31 < Cracki> it would be nice if it's just the pcb that broke, but that's quite unlikely
2017-11-15T00:56:47 < Cracki> does it spin up?
2017-11-15T00:57:02 < Cracki> (feel inertia when tilting?)
2017-11-15T00:57:47 < Cracki> likely the head is fucked and doesn't see tracks anymore.
2017-11-15T00:57:53 < kakimir> it spins up
2017-11-15T00:58:02 < kakimir> I saw it visually
2017-11-15T00:58:06 < Cracki> visually
2017-11-15T00:58:06 < kakimir> to spin up
2017-11-15T00:58:14 < kakimir> visual confirmed
2017-11-15T00:58:15 < Cracki> opened it up already?
2017-11-15T00:58:20 < kakimir> whoops
2017-11-15T00:58:22 < Cracki> hope not, doesn't help
2017-11-15T00:58:35 < Cracki> there's nothing of value inside a hdd, except the bits
2017-11-15T00:58:56 < Cracki> all you can add is dust
2017-11-15T00:59:05 < Cracki> and that's less than helpful
2017-11-15T00:59:59 < Cracki> best chance at getting the data is bringing it to a lab that can read the platters outside the disk
2017-11-15T01:00:12 < Cracki> they'll prolly have an assortment of PCBs to try first
2017-11-15T01:01:18 < jadew> and another assortment of prices

2017-11-15T01:27:21 < englishman> you just buy it
2017-11-15T01:27:23 < englishman> switches r cheap
2017-11-15T01:27:31 < upgrdman> englishman, poe switches tho?
2017-11-15T01:27:33 < Cracki> poe switches not so much
2017-11-15T01:27:35 < englishman> its 44V man, its not going to yolo that over ethernet randombly
2017-11-15T01:27:41 < Cracki> 48v*
2017-11-15T01:27:44 < englishman> that would make many people sad
2017-11-15T01:27:45 < englishman> yeah ^

2017-11-15T01:28:17 < englishman> 10/100 lol
2017-11-15T01:28:22 < Cracki> poe works by using pairs for power only
2017-11-15T01:28:34 < Cracki> you will have to give up copper for power
2017-11-15T01:28:45 < upgrdman> oh god. updating win10 in one of my vm's. its doing that stupid "hi" "this might take several minutes" "..." while slowly changing colors. such rage.
2017-11-15T01:28:48 < englishman> yeah i forgot about that
2017-11-15T01:29:03 < englishman> guess there arent any that do gigabutt when not in poe mode? or gigabutt uplink?
2017-11-15T01:29:07 < upgrdman> i want to deliver ARSE PAIN to the managers as msft that thought this was a good idea
2017-11-15T01:29:15 < Cracki> there are though

2017-11-15T01:30:12 < Cracki> afaik those put a bias between the differential pair and the shield
2017-11-15T01:30:24 < englishman> probably not huge power requirement
2017-11-15T01:30:26 < Cracki> not sure tho
2017-11-15T01:30:30 < Cracki> indeed

2017-11-15T01:31:40 < Laurenceb_> how network formed
2017-11-15T01:31:42 < Cracki> also afaik poe is DC, not AC, so that one comment is just mostly right
2017-11-15T01:31:59 < upgrdman> wat
2017-11-15T01:32:04 < upgrdman> i thought poe was ac
2017-11-15T01:32:19 < Cracki> I shall check
2017-11-15T01:32:26 < Laurenceb_> lulwut
2017-11-15T01:32:30 < upgrdman> i guess dc makes sense tho. less noise from dc/dc
2017-11-15T01:32:31 < Laurenceb_> poe is DC bro
2017-11-15T01:32:37 < upgrdman> ok fine.
2017-11-15T01:32:44 < Cracki> wikipedia says nothing about AC
2017-11-15T01:33:03 < upgrdman> i should just make my own poe switch, with hooked and blackjack. 48VDC ALL THE PINS
2017-11-15T01:33:06 < Laurenceb_> nevar forget https://cdn.sparkfun.com//assets/parts/7/0/8/7/11361-03.jpg
2017-11-15T01:33:07 < Cracki> no actually, ac just is inconvenient I'd say
2017-11-15T01:33:31 < Cracki> tho probably propagates more easily
2017-11-15T01:33:39 < Cracki> hm, not even that!

2017-11-15T01:34:48 < upgrdman> not very kawaii.
2017-11-15T01:34:51 < Getty> i found it always kinda confusing that we have those ethernet via power devices but no movement of devices that are lan connected via power

2017-11-15T01:36:11 < Laurenceb_> why they couldnt put it on the main pcb boggles the mind
2017-11-15T01:36:12 < Cracki> down from what, mains?
2017-11-15T01:36:17 < Laurenceb_> 48v or so
2017-11-15T01:36:29 < Cracki> those components look huge
2017-11-15T01:37:14 < Laurenceb_> welcome to arduino land
2017-11-15T01:37:30 < upgrdman> was probably the cheapest way to get a 48V -> 5V DCDC
2017-11-15T01:37:53 < upgrdman> i mean theres lots of SO8 + SMD L/C ways to do it, but not for super cheap
2017-11-15T01:38:03 < upgrdman> >24Vin DCDC tends to be pricey
2017-11-15T01:38:51 < Laurenceb_> so many tarduino boards

2017-11-15T01:42:02 < Laurenceb_> if thats a sigfox module I would buy the modules
2017-11-15T01:42:22 < kakimir> active poe is when you want to power whole computer based client or so
2017-11-15T01:42:32 < kakimir> at least the highest power options
2017-11-15T01:42:50 < kakimir> 75W power iirc
2017-11-15T01:43:05 < kakimir> low power shiet just uses passive usua
2017-11-15T01:43:07 < Laurenceb_> oh nice
2017-11-15T01:43:08 < kakimir> lly
2017-11-15T01:43:24 < Laurenceb_> tarduino sell sigfox modules with 140messages/day for 2 years

2017-11-15T01:48:34 < Laurenceb_> it runs on ism band with 20mw or so
2017-11-15T01:48:36 < upgrdman> what freq does it use
2017-11-15T01:48:38 < upgrdman> 2.4?
2017-11-15T01:48:41 < Laurenceb_> 434 or 868
2017-11-15T01:48:55 < upgrdman> and theres like cell tower or something it talks to?
2017-11-15T01:49:19 < Laurenceb_> yeah

2017-11-15T04:20:32 < englishman> also I don't think they call it libc
2017-11-15T04:21:02 < branjb> isn't there some version of newlib-nano w/o printf support, or it's just stubbed
2017-11-15T04:21:07 < branjb> I seem to remember that somewhere
2017-11-15T04:22:03 < englishman> this is Keil tho not lunix crap
2017-11-15T04:23:05 < msichal> sprintf works fine
2017-11-15T04:23:23 < msichal> but it can't find vsprintf or vsnprintf
2017-11-15T04:24:07 < msichal> and I can't even google anything, all I can find using keil + vsprintf is some '51 documentation for keil, which includes vsprintf
2017-11-15T04:25:09 < msichal> maybe I'll try adding GCC to keil...
2017-11-15T04:25:43 < englishman> are you using armcc or the new clang one
2017-11-15T04:29:55 < msichal> I think I've tried every compiler, they're just named version 5 or 6, I think 6 would be the clang
2017-11-15T04:30:47 < msichal> well, every -there are 4 options available, but two of them are basically default ver 5 and default ver 6, so remaining two would probably do the same
2017-11-15T04:31:28 < msichal> also disabling "use microlib" doesn't work either

2017-11-15T12:46:34 < jsoft> I am trying to change a global char to -1 in an interrupt handler. For some reason, the main loop which checks for != 0 on the same variable, never thinks it is < 0. Any ideas?
2017-11-15T12:46:52 < jpa-> jsoft: have you specified it to be "volatile"?
2017-11-15T12:47:07 < stvn> greeting
2017-11-15T12:47:08 < zyp> no, he haven't, and that's the problem
2017-11-15T12:47:13 < jpa-> otherwise if the main loop never calls any external functions, the compiler can assume that the variable cannot change
2017-11-15T12:48:12 < jsoft> jpa-, yes
2017-11-15T12:48:50 < zyp> jsoft, pastebin your code?
2017-11-15T12:50:17 < jsoft> https://pastebin.com/tVXLnjk0
2017-11-15T12:50:39 < zyp> that's not enough
2017-11-15T12:50:52 < jpa-> i see no globals there
2017-11-15T12:51:04 < jsoft> the global is volatile char filter_changed
2017-11-15T12:51:14 < jsoft> the global is volatile char filter_change I mean
2017-11-15T12:51:20 < stvn> lol
2017-11-15T12:52:01 < jpa-> jsoft: is char signed or unsigned on your toolchain?
2017-11-15T12:52:18 < jpa-> (IIRC it is unsigned by default on cortex-m gcc)
2017-11-15T12:52:26 < jsoft> I am using gcc.
2017-11-15T12:52:49 < zyp> the argument to the exti callback looks like a bitmap, if so you're assuming that only one of those bits can be set at a time
2017-11-15T12:53:45 < jpa-> jsoft: so your char type is unsigned and it will not be less than 0
2017-11-15T12:54:35 < jsoft> Ok, so a short or a long should be unsigned right?
2017-11-15T12:54:51 < jpa-> *signed, yeah, you can use int or "signed char" if you really want
2017-11-15T12:54:56 < zyp> why not use stdint types?

2017-11-15T12:55:31 < jpa-> it rarely makes sense to use short and char on 32 bit platforms, as the compiler may have to emit extra instructions to mask the top bits
2017-11-15T12:55:53 < zyp> that too
2017-11-15T12:56:26 < jpa-> i just use 'int' in most places
2017-11-15T12:56:35 < jsoft> ok well, int8_t no change.
2017-11-15T12:56:38 < jsoft> long, no change.
2017-11-15T12:56:58 < jsoft> i must be missing something captain obvious here
2017-11-15T12:57:03 < jpa-> so does the variable actually change when you check with debugger?
2017-11-15T12:57:10 < zyp> jsoft, did you see what I said about bitmap?
2017-11-15T12:59:11 < jsoft> zyp, ok
2017-11-15T12:59:40 < zyp> I kinda doubt that's your main issue now, but it's still something that could bite you
2017-11-15T12:59:57 < jsoft> zyp, I get what you are saying, but unless there is some weird thing I am missing, the filter_change = -1; is for sure being triggered.
2017-11-15T13:00:20 < zyp> how do you tell?
2017-11-15T13:00:41 < jsoft> I can see a change on the scope.

2017-11-15T13:01:00 < jsoft> A change. It works.
2017-11-15T13:01:09 < jsoft> So it is changing the filter.
2017-11-15T13:01:26 < jsoft> I see a pause in filter output, and then it carries on.
2017-11-15T13:01:33 < jsoft> Comment it out, continuous
2017-11-15T13:01:38 < jpa-> so it is working now after you fixed the char bug?
2017-11-15T13:01:45 < jsoft> No it is not working.
2017-11-15T13:02:04 < zyp> you are not being very clear on what is working and what is not
2017-11-15T13:02:24 < zyp> 12:01:00 < jsoft> A change. It works.
2017-11-15T13:02:26 < jsoft> Ok so what is not working, is that it never seems to think change_filter is < 0
2017-11-15T13:02:27 < zyp> 12:01:45 < jsoft> No it is not working.
2017-11-15T13:02:38 < jsoft> filter_change I mean
2017-11-15T13:02:57 < jsoft> But it does not see it as < 0.
2017-11-15T13:03:07 < jpa-> what does it do instead?
2017-11-15T13:03:20 < jsoft> It sees it as > 0
2017-11-15T13:03:35 < jpa-> but your > 0 condition doesn't do anything
2017-11-15T13:04:08 < jsoft> It does if I uncomment it.
2017-11-15T13:04:13 < jsoft> It increments the filter.
2017-11-15T13:04:36 < jpa-> and how do you determine that an increment of filter is occurring and a decrement is not occurring?
2017-11-15T13:04:44 < jsoft> oled display
2017-11-15T13:05:45 < jpa-> why not just put a breakpoint there on lines 8 and 11 and see what value filter_change really has?
2017-11-15T13:05:46 < jsoft> In addition the filter output changes in accordance with the filter
2017-11-15T13:05:58 < jsoft> I've not set up debgging stuff yet
2017-11-15T13:06:05 < jpa-> do that now
2017-11-15T13:06:14 < jpa-> otherwise you'll just be wasting your and our time

2017-11-15T13:59:30 < jpa-> yeah, seems so
2017-11-15T13:59:58 < Lux> or if you know how much data is transfered and are using dma you could use the dma interrupt
2017-11-15T14:00:28 < Lux> but i guess that's rarely the case

2017-11-15T14:02:35 < jpa-> yeah, i don't want to rely on it because then even a single too short transfer would cause it to do out of sync

2017-11-15T14:06:44 < zyp> I ended up just not caring about NSS at all and using byte timing instead
2017-11-15T14:07:08 < jpa-> byte timing?
2017-11-15T14:07:20 < zyp> i.e. state machine resets if there's been a ~2ms gap between bytes

2017-11-15T14:08:06 < zyp> I can do it because I know that the master is issuing commands at a fixed interval significantly longer than that

2017-11-15T15:51:15 < kakimir> ES120 is really nice for laptop repairs and such
2017-11-15T15:51:26 < kakimir> screws are removed like boom boom
2017-11-15T15:54:18 < BrainDamage> well, it does't just remove makeup it arbitrarily introduces defects that may or may be not be there originally

2017-11-15T16:35:54 < Laurenceb> I see they have been hard at work
2017-11-15T16:37:44 < kakimir> is eagle free anymore?
2017-11-15T16:38:16 < kakimir> or any better than it was?
2017-11-15T16:38:24 < Laurenceb> yes there is a free eagle
2017-11-15T16:38:31 < Laurenceb> 2 layers with size limit as before aiui
2017-11-15T16:38:37 < kakimir> autodesk is making money out of turds
2017-11-15T16:38:46 < BrainDamage> eagle is subscription only now
2017-11-15T16:38:54 < Laurenceb> apparently kicad is now usable
2017-11-15T16:38:59 < kakimir> they know monitarization
2017-11-15T16:39:00 < Laurenceb> wut
2017-11-15T16:39:06 < BrainDamage> you can always pretend you're a student to get it free for a while
2017-11-15T16:39:08 < Laurenceb> I downloaded it about 4 weeks ago
2017-11-15T16:39:20 < Laurenceb> maybe I got warez, I forget
2017-11-15T16:40:18 < BrainDamage> oh, nvm they kept the free version
2017-11-15T16:40:23 < BrainDamage> i tought they removed it
2017-11-15T16:40:58 < Laurenceb> ree why is methlab so slow
2017-11-15T16:41:00 < kakimir> okay they want autodesk account
2017-11-15T16:41:06 < Laurenceb> >write a simple loop
2017-11-15T16:41:11 < Laurenceb> >it takes 20 minutes to run
2017-11-15T16:41:21 < kakimir> anyone have pre-autodesk binaries?
2017-11-15T16:41:30 < kakimir> to illegally distribute to me
2017-11-15T16:41:47 < BrainDamage> because you're not supposed to have loops in methlab, you're supposed to build pipelines with the builtin tools
2017-11-15T16:41:56 < Laurenceb> ikr
2017-11-15T16:41:59 < Laurenceb> so stupid

2017-11-15T19:33:19 < zyp> oh
2017-11-15T19:33:24 < englishman> i had to ask the client if they got there
2017-11-15T19:33:26 < zyp> so why aren't they paid?
2017-11-15T19:33:29 < englishman> as i never got an invoice or ship notice

2017-11-15T21:15:09 < TheSeven> hmm seems like on f2, the timers don't like being written to with byte accesses
2017-11-15T21:15:11 < TheSeven> they duplicate the written data into the high byte :/
2017-11-15T21:15:23 < zyp> is this unique to f2?
2017-11-15T21:15:24 < TheSeven> and it doesn't look like I can tell DMA to zero-extend data (unlike on F0)
2017-11-15T21:17:09 < TheSeven> wastes quite a lot of RAM :/
2017-11-15T21:18:02 < TheSeven> some clever idea how I can bitbang a manchester encoded signal (ws2811) in the background?
2017-11-15T21:18:43 < zyp> manchester?
2017-11-15T21:19:04 < TheSeven> ones and zeros encoded by pulses of different duty cycle

2017-11-15T21:19:46 < zyp> last I checked, manchester encodes were ones and zeros encoded by opposite phases
2017-11-15T21:20:04 < TheSeven> hmm... what was this called then
2017-11-15T21:20:17 < zyp> idk, but I've also done that
2017-11-15T21:20:42 < zyp> although I did it on f3, so I also read from 8 bit into a timer
2017-11-15T21:20:43 < TheSeven> DMA + timers is one way, but it blows up the data by a factor of 16 on F2
2017-11-15T21:20:57 < upgrdman> anyone used lwip? decent? any quirks i should know about. will be sending and receiving udp packets.
2017-11-15T21:21:35 < TheSeven> I guess I could also use a timer to trigger DMA writes to GPIO ports or something...
2017-11-15T21:21:46 < zyp> TheSeven, I have an idea, give me a moment
2017-11-15T21:22:02 < qyx> TheSeven: cannot you use usart+dma for that?
2017-11-15T21:22:13 < qyx> like they are doing with dallas 1wire
2017-11-15T21:22:39 < TheSeven> I could probably abuse a uart or SPI or whatnot to bitbang one of those at a time
2017-11-15T21:22:50 < TheSeven> timers or GPIO-DMA allow for multiple in parallel
2017-11-15T21:23:19 < zyp> TheSeven, which data rate was ws2811 again?
2017-11-15T21:23:23 < TheSeven> 800kHz
2017-11-15T21:23:36 < zyp> and the two duty targets are?
2017-11-15T21:24:38 < TheSeven> 20% and 48%
2017-11-15T21:25:29 < TheSeven> with carefully synced timers, I could have two DMA channels writing the rising edge and the (second) falling edge by throwing constant values at a GPIO, then have a third channel inject the actual data bit in the middle
2017-11-15T21:25:46 < zyp> yeah, I've thought about that before
2017-11-15T21:26:40 < zyp> all you need in that case is to transpose an array of rgb values to an array of bit-groups
2017-11-15T21:26:52 < zyp> makes sense if you have more than one channel
2017-11-15T21:26:59 < zyp> not so much if you only have one
2017-11-15T21:28:02 < TheSeven> I have 4 in this case on consecutive GPIOs, but annoyingly spanning a byte boundary :/
2017-11-15T21:28:38 < zyp> that doesn't matter, you'd still have to write the entirety of BSRR if you wanna use other pins on the same port for anything else
2017-11-15T21:28:53 < zyp> but still
2017-11-15T21:29:15 < TheSeven> if I had planned this before designing the hardware, I could have got away with a GPIO port that has all pins but those on input or AF
2017-11-15T21:30:04 < zyp> is 24*4 bytes really that much for a temporary buffer?
2017-11-15T21:30:31 < zyp> or are you planning to buffer more than one rgb value?
2017-11-15T21:30:36 < TheSeven> I'll probably have to size it quite a bit bigger if I don't want to run into IRQ latency issues
2017-11-15T21:31:16 < zyp> nah, doing a pause in between 24-bit groups is not a big deal
2017-11-15T21:31:18 < zyp> I do that
2017-11-15T21:31:32 < TheSeven> depends on the length of the pause
2017-11-15T21:32:47 < TheSeven> and you'd have to end all groups with an intentional bit of pause to ensure that the timer doesn't produce spurious bits
2017-11-15T21:32:51 < zyp> yes
2017-11-15T21:32:53 < zyp> https://cgit.jvnv.net/arcin/tree/arcin/main.cpp?id=8d37e2d#n64
2017-11-15T21:33:09 < TheSeven> I'd prefer to produce a 100% clean signal if possible
2017-11-15T21:34:02 < zyp> hmm
2017-11-15T21:34:21 < TheSeven> and I'm targeting to drive 4 channels of up to 9600 bits frame size each (5 meters of RGBW strip)
2017-11-15T21:34:36 < zyp> TI's N2HET would proably do a good job at this
2017-11-15T21:36:04 < TheSeven> hmm I'm currently looking at the IRQ priorities, and I could probably get away with a 100µs IRQ latency requirement at that priority level
2017-11-15T21:36:25 < TheSeven> I also don't want to block for too long, as I have other timer IRQs (millisecond ticks etc.) at lower priorities
2017-11-15T21:37:16 < TheSeven> let's assume I can generate data twice as fast as the DMA consumes it, so I'd need ~500µs of buffer
2017-11-15T21:37:43 < zyp> that sounds really slow
2017-11-15T21:38:46 < TheSeven> that would be 400 timer ticks, i.e. 800 bytes of buffer per channel, i.e. 3.2KB total - I can probably live with that, but this kind of thing just annoys me
2017-11-15T21:41:57 < englishman> what's the TI document that explains package markings
2017-11-15T21:42:37 < TheSeven> hmm, actually IRQ priority might be shorter, that 100µs is generous
2017-11-15T21:42:45 < zyp> the reset time gap is specified to >50us, that's 6000 cycles
2017-11-15T21:42:54 < zyp> on 120MHz
2017-11-15T21:42:59 < TheSeven> I'm certain that there will be >10µs latency, but it might well be that it's never more than around 20-30
2017-11-15T21:43:11 < zyp> why?
2017-11-15T21:43:27 < TheSeven> I have an annoying high-priority IRQ that needs to talk SPI
2017-11-15T21:43:45 < zyp> which needs to be higher than this?
2017-11-15T21:43:48 < TheSeven> yes
2017-11-15T21:43:57 < TheSeven> latency requirements in the order of <10µs for that SPI access
2017-11-15T21:44:44 < TheSeven> stupid radio chip
2017-11-15T21:45:06 < zyp> which can't be DMAed?
2017-11-15T21:45:26 < TheSeven> no, it's a bit more complex than that
2017-11-15T21:45:46 < zyp> fair enough
2017-11-15T21:48:32 < TheSeven> so I think I'll try to go for 2x 192 bit buffers per channel (~1.5K total RAM use) and see if that works reliably
2017-11-15T21:49:14 < TheSeven> this board will quite likely get a respin sooner or later anyway, where I'll probably re-route this to more conveniently DMAable GPIOs
2017-11-15T21:49:28 < zyp> oh, by the way
2017-11-15T21:49:37 < TheSeven> that said, do GPIOs show the same duplicating effect if you write bytes to the registers?
2017-11-15T21:49:44 < TheSeven> that might actually come in handy if they do
2017-11-15T21:50:07 < zyp> I was going to suggest using DMA to extend the buffer
2017-11-15T21:50:11 < TheSeven> the only other output pins on port C are some status LEDs
2017-11-15T21:50:39 < TheSeven> as in convert bytes to halfwords?
2017-11-15T21:50:52 < zyp> use one dma job doing 8-bit transfers from the main buffer to a single word intermediate buffer, then another dma job from the intermediate buffer to the register
2017-11-15T21:51:15 < TheSeven> hmm, interesting idea, if I manage to get the triggering of that right
2017-11-15T21:51:17 < zyp> keep upper half of intermediate buffer at 0 and it'd stay like that since memory supports 8-bit transfers
2017-11-15T21:51:49 < zyp> I think I discarded it because four channels then means 8 dma jobs
2017-11-15T21:52:13 < TheSeven> nah, not at all
2017-11-15T21:52:21 < TheSeven> you can do 4 channels with one DMA stream
2017-11-15T21:52:36 < zyp> for the last half, maybe
2017-11-15T21:52:37 < TheSeven> the problem is getting the timing between the reading and writing channel right
2017-11-15T21:53:14 < zyp> shouldn't be a problem
2017-11-15T21:53:16 < TheSeven> I was wondering if bit banding can be used in some way here, but I guess that's not accessible by DMA and could at best be used for data preprocessing somewhere
2017-11-15T21:53:34 < zyp> just trigger one from the timer update event and the other from the channel compare event
2017-11-15T21:53:48 < TheSeven> that won't work with interleaved channels
2017-11-15T21:53:50 < zyp> hehe
2017-11-15T21:54:03 < zyp> why not?
2017-11-15T21:54:51 < TheSeven> hmm... or wait... I can tell the DMA to increment by 4 despite just writing one byte, but I guess I can't make it go back to the beginning of the buffer after completing 4 bytes
2017-11-15T21:55:05 < zyp> oh, and if you're going that route, make sure your timer can trigger the dma peripheral that can access memory with both the M and the P ports
2017-11-15T21:59:03 < TheSeven> hm, what's faster... reading data using bit banding or a byte at a time (and then shifting the bits out)
2017-11-15T21:59:09 < TheSeven> (for preprocessing code)
2017-11-15T22:08:15 < englishman> hmm
2017-11-15T22:08:29 < englishman> i may have blown up all these ATSAM3X boards because a level shifter was installed backwards

2017-11-15T23:45:15 < ohsix> every one of these arduino projects needs to have 'reset all parameters' thing at the beginngin cuz they zombify the module to other things
2017-11-15T23:47:47 < ohsix> also nobody knows what they're doing, but there are a million posts offering solutions ;D that's some pretty good evidence that on balance arduino made the world worse
2017-11-15T23:50:02 < upgrdman> FUCK. turns out my intermittent electrical problem isnt going to be cheap to fix. http://www.farrellf.com/temp/behind_meter.jpg
2017-11-15T23:50:22 < upgrdman> send out RFQs but Edison told me not to be surprised if >$1000
2017-11-15T23:50:45 < englishman> wut
2017-11-15T23:51:07 < upgrdman> supposedly that connector is not available separately and the whole fucking panels would need to be swapped
2017-11-15T23:51:11 < englishman> isnt that just the meter box
2017-11-15T23:51:14 < upgrdman> yes
2017-11-15T23:51:15 < englishman> is it even your property
2017-11-15T23:51:27 < upgrdman> yes, condo, and im responsible for my elec

2017-11-15T23:52:10 < upgrdman> the plastic it's sitting in is deformed :(
2017-11-15T23:52:17 < upgrdman> was arcing a lot supposedly
2017-11-15T23:52:21 < upgrdman> and i believe it
2017-11-15T23:52:36 < englishman> nice
2017-11-15T23:52:41 < upgrdman> that photo doesnt have good lightly. the plastic base is crispy and fucked.

2017-11-15T23:53:44 < TheSeven> wtf am I missing
2017-11-15T23:53:46 < qyx> such a weird electrical box
2017-11-15T23:54:12 < upgrdman> qyx, its where power goes into the building. theres a "normal" looking breaker box in my home
2017-11-15T23:54:30 < TheSeven> I seem to be getting high impedance output on timer capture/compare outputs - not quite sure why
2017-11-15T23:54:46 < TheSeven> stm32f205, tim8 ch1-4 on pc6-9
2017-11-15T23:55:04 < TheSeven> GPIO config is AF, source 3
2017-11-15T23:55:06 < upgrdman> TheSeven, enables clocks for gpio AND timer?
2017-11-15T23:55:20 < TheSeven> timer seems to be accepting register writes at least
2017-11-15T23:55:31 < TheSeven> BDTR.MOE is set
2017-11-15T23:55:45 < TheSeven> CCER.CCxE are set
2017-11-15T23:55:52 < TheSeven> OCxM = 6
2017-11-15T23:55:55 < TheSeven> what am I missing?
2017-11-15T23:55:58 < upgrdman> gpio clocks
2017-11-15T23:56:10 < TheSeven> I'm fairly confident that GPIO is set up correctly
2017-11-15T23:56:43 < TheSeven> GPIO clocks only need to be on while configuring the pin
2017-11-15T23:57:38 < qyx> upgrdman: yep, but the american boxes are quite different
2017-11-15T23:58:13 < qyx> there are things like http://www.dobraradanadzlato.sk/stavbard/obr/zaklady/DSCN1554.JPG
2017-11-15T23:58:25 < qyx> this one is actually without the meter
2017-11-15T23:58:39 < qyx> just prepared for installation
2017-11-15T23:58:57 < upgrdman> this is kinda what mine look like, but we're stacked in a grid, not just left-to-rigth http://delafleur.com/blog/wp-content/uploads/2011/06/meter-bank.jpg
2017-11-15T23:59:18 < upgrdman> qyx, that doesnt look like a meter?
--- Day changed Thu Nov 16 2017
2017-11-16T00:00:34 < upgrdman> the breaker panel, inside the home, looks kinda like this https://i.pinimg.com/originals/c3/27/fa/c327fa1e2af63298f0cee2f93a8ae755.jpg

2017-11-16T06:41:45 < jadew> what's the cheapest MCU that can drive a VGA TFT?
2017-11-16T06:41:52 < jadew> 640x480
2017-11-16T06:42:52 < jadew> that's what I meant by VGA - resolution

2017-11-16T06:55:41 < emeb_mac> an stm32f426/427 can probably do it - it has the lcd output logic
2017-11-16T06:56:25 < emeb_mac> but you'd probably need an external memory to hold the frame buffer, so that means a high pincount pkg and a SDRAM
2017-11-16T06:56:40 < emeb_mac> so "cheap" becomes kind of a fuzzy concept
2017-11-16T06:56:54 < jadew> yeah, I don't want external memory
2017-11-16T06:57:01 < jadew> it needs about 300 kb of RAM
2017-11-16T06:57:24 < emeb_mac> not many parts have that much on-chip
2017-11-16T06:57:33 < emeb_mac> an F746 has 320kB
2017-11-16T06:57:37 < jadew> yeah
2017-11-16T06:57:41 < jadew> but it costs like $20
2017-11-16T06:58:13 < emeb_mac> nah
2017-11-16T06:58:20 < emeb_mac> you can get them cheaper than that.
2017-11-16T06:58:31 < jadew> from where?
2017-11-16T06:59:51 < emeb_mac> https://www.digikey.com/product-detail/en/stmicroelectronics/STM32F746ZET6/497-16611-ND/6137822
2017-11-16T07:00:12 < jadew> that's a good price
2017-11-16T07:00:14 < jadew> thanks
2017-11-16T07:00:26 < jadew> I have to start searching digikey from now on
2017-11-16T07:02:06 < emeb_mac> they're not the best price but pretty consistent at least
2017-11-16T07:02:12 < emeb_mac> verical has some too: https://www.verical.com/pd/stmicroelectronics-microcontroller-stm32f746zet6-2113435

2017-11-16T07:04:13 < jadew> I don't think the 746 can do it
2017-11-16T07:04:20 < jadew> 64k of that RAM is TCM
2017-11-16T07:05:09 < emeb_mac> it's all accessible to DMA
2017-11-16T07:05:28 < emeb_mac> but you'd have to code pretty tight to fit it all in
2017-11-16T07:05:31 < jadew> in one continous chunk?
2017-11-16T07:05:36 < emeb_mac> yeah
2017-11-16T07:05:45 < emeb_mac> memory map of SRAM has no gaps
2017-11-16T07:06:07 < jadew> interesting, I'll get the discovery board and see how that works out, thanks

2017-11-16T07:10:01 < emeb_mac> looks like the F7 LCD interface has a color LUT so you could cut it down to 4bpp and still get full color
2017-11-16T07:12:27 < emeb_mac> and a ditherer so you can go even lower

2017-11-16T07:18:26 < emeb_mac> cool
2017-11-16T07:18:51 < jadew> thanks again
2017-11-16T07:21:32 < emeb_mac> that discovery board is a pretty good deal for what they charge.
2017-11-16T07:21:44 < emeb_mac> huge display, memory, networking, etc.
2017-11-16T07:22:02 < emeb_mac> you can use the external memory or not.
2017-11-16T07:23:02 < jadew> didn't even notice it has external SDRAM
2017-11-16T07:28:36 < emeb_mac> yep
2017-11-16T07:32:45 < emeb_mac> I've done a couple F4 and F7 boards with external SDRAM. It's pretty easy and the parts aren't too expensive.
2017-11-16T07:45:17 < ohsix> upgrdman's thing isn't going to be a thousand buxxx
2017-11-16T07:45:41 < ohsix> even if you pay someone, and if you don't; chief cost is getting the power co to unhook that side of things and hook it back up
2017-11-16T07:46:47 < ohsix> also normal ass, boring meter box
2017-11-16T07:48:01 < englishman> hi emeb
2017-11-16T07:48:06 < englishman> what's innovating
2017-11-16T07:48:12 < ohsix> distributors don't stock old parts cuz they dont' interchange very well
2017-11-16T07:50:06 < emeb_mac> englishman: not a lot. head-down working on $DAYJOB for the last few months. not IRCing much.
2017-11-16T07:51:04 < emeb_mac> did a little breakout board for an L432 in QFN32 a few weeks back but that's about all the HW I've messed with lately.
2017-11-16T07:51:19 < englishman> what was that for?
2017-11-16T07:51:38 < englishman> this chan is lacking innovations lately
2017-11-16T07:52:02 < emeb_mac> spec project for an underwater data collection system. has to run for 1yr on batteries so needs super low power.
2017-11-16T07:52:25 < Thorn> IIRC the I2S codec IC on the 746 disco is even more expensive than the F7 itself in digikey
2017-11-16T07:52:46 < emeb_mac> haha
2017-11-16T07:53:14 < emeb_mac> I don't know how they sell those large discos so cheap - must be buying in w/ marketing bux

2017-11-16T11:17:37 < ohsix> with the way it evaporates it would probably be a boom cloud
2017-11-16T11:18:15 < jadew> yeah, I understand alcohol baths are common after ultrasonic cleaning
2017-11-16T11:18:23 < jadew> to displace the water

2017-11-16T14:44:06 < PaulFertser> (drawing with a guide, cutting without)
2017-11-16T14:44:19 < zyp> is glass even worth dicking around with?

2017-11-16T14:45:29 < Lux> imo the best thing is pei coated aluminium
2017-11-16T14:45:40 < Lux> expensive, but works like a charm
2017-11-16T14:45:43 < zyp> that's the impression I've got as well
2017-11-16T14:47:21 < PaulFertser> Preliminary results with 120mm/s look pretty nice.
2017-11-16T14:48:04 < Lux> PaulFertser: are you running that pressure advance stuff ?
2017-11-16T14:48:09 < PaulFertser> Lux: no
2017-11-16T14:48:26 < Lux> imo at those speeds you allready get small issues with corners being rounder etc
2017-11-16T14:49:01 < zyp> https://clever3d.de/epages/7a4290fc-7c7f-46cc-9b99-eadef22228e2.sf/en_US/?ObjectPath=/Shops/7a4290fc-7c7f-46cc-9b99-eadef22228e2/Products/c3d-DDP-PEI-natur <- I figure I'll get one of these when I get around to building a decent printer
2017-11-16T14:49:02 < PaulFertser> But I'm not using bowden here
2017-11-16T14:49:06 < Lux> it's not a major issue, but noticeable even with direct drive
2017-11-16T14:49:18 < PaulFertser> Lux: yeah, we'll see. It's a test draft print anyway.
2017-11-16T14:49:44 < Lux> zyp: that's what i got
2017-11-16T14:49:52 < zyp> :)
2017-11-16T14:49:56 < zyp> is it as good as it seems?
2017-11-16T14:50:22 < Lux> so far it works really well for pla and abs
2017-11-16T14:50:33 < zyp> tried PETG?
2017-11-16T14:50:48 < Lux> petg sticks a bit too well, but i guess you can fix that by playing with the temperatures
2017-11-16T14:51:07 < Lux> or using windex apparently works too
2017-11-16T14:51:12 < PaulFertser> Surface temperature for ABS : least 135Grad <- whoah
2017-11-16T14:51:35 < Lux> yeah, you need a 200W heat mat for that
2017-11-16T14:52:04 < PaulFertser> My anet a8 is actually able to go to 135C after 30 minutes of heating :)
2017-11-16T14:52:17 < Lux> but then it sticks really well and below 60°C or so the part just pops off
2017-11-16T14:52:32 < PaulFertser> Same with my glass at 110C
2017-11-16T14:52:44 < zyp> is PETG sticking much of a concern? I figure you can use enough of force to get it off without risking damage to the surface
2017-11-16T14:52:52 < Lux> but then you need hairspray or whatever for it to stick
2017-11-16T14:53:05 < sync> PaulFertser: I run my a8 at 24V
2017-11-16T14:53:12 < sync> so it actually is able to get there quickly
2017-11-16T14:53:33 < Lux> zyp: yeah, so far i haven't managed to damage the surface
2017-11-16T14:53:43 < PaulFertser> sync: just 24V psu, no other mods? I'm using factory psu at 14.4V or so.
2017-11-16T14:54:39 < zyp> I've found that printing PETG on cold buildtak is pretty finicky
2017-11-16T14:55:08 < sync> yeah PaulFertser
2017-11-16T14:55:09 < zyp> I've got corners curling regularly, but I've also managed to rip hole in the buildtak where something stuck too well
2017-11-16T14:55:19 < Lux> zyp: I killed a buildtak sheet with petg, stuck too well
2017-11-16T14:55:27 < PaulFertser> sync: how about the fans?
2017-11-16T14:55:41 < sync> did nothing to them
2017-11-16T14:55:48 < zyp> I just don't print on that spot anymore :p
2017-11-16T14:55:56 < zyp> but yeah
2017-11-16T14:55:59 < PaulFertser> I mean the extruder motor fan, it seems to be connected directly to the power rail.
2017-11-16T14:56:19 < sync> yeah, it just runs all the time
2017-11-16T14:57:09 < Lux> PaulFertser: are you printing abs directly on the glass bed at 110°C ? or are you using some glue/hairspray ?
2017-11-16T14:58:57 < PaulFertser> Lux: the cheapest "strong hairspray" from auchan.
2017-11-16T14:59:39 < Lux> the point is with pei you just need to clean the surface once in a while :)
2017-11-16T15:00:04 < Lux> years ago I used beer on glass which seemed to work well too at 110°C
2017-11-16T15:08:58 < PaulFertser> Steffanx: so how do you calibrate bed distance? Metal feeler gauge seems to work ok here.

2017-11-16T15:24:50 < BrainDamage> don't you risk that weather variation will have a way stronger impact?
2017-11-16T15:25:08 < Laurenceb> sure but you can high pass filter out the vehicle path
2017-11-16T15:25:20 < Laurenceb> this would be fun to try simulating
2017-11-16T15:26:25 < Steffanx> Yes, like that, but i did that just in thr corners, so didnt really notice the glass issue, PaulFertser
2017-11-16T15:26:44 < jadew> Steffanx, yeah, I'm aware about the tape issue, I'll replace it
2017-11-16T15:27:10 < BrainDamage> i feel like in practical pourposes, a simple gps module will get you more simplicity and reliability
2017-11-16T15:27:13 < jadew> qyx, I have some special flux remover for ultrasonic cleaners in the basket
2017-11-16T15:27:25 < BrainDamage> the only annoyance is the sky view
2017-11-16T15:27:30 < Laurenceb> BrainDamage: but gps needs power and sky view
2017-11-16T15:27:55 < emeryth> and baro doesn't?
2017-11-16T15:27:57 * Laurenceb is thinking of ~10mm diameter micro device thats magnetic and goes onto bottom of vehicles
2017-11-16T15:28:04 * Laurenceb applies for jerb at NSA
2017-11-16T15:28:30 < Laurenceb> disguised as a fleck of muck
2017-11-16T15:28:47 < BrainDamage> you probably don't even need to disguise it
2017-11-16T15:28:55 < BrainDamage> nobody checks the underside of a vehicle
2017-11-16T15:29:42 < Laurenceb> unless its high security stuff
2017-11-16T15:29:56 < Laurenceb> NSA here I come
2017-11-16T15:30:16 < emeryth> Laurenceb: if it goes on the bottom, all you need is a computer mouse optical sensor
2017-11-16T15:30:20 < emeryth> tracking done
2017-11-16T15:30:35 < Laurenceb> lithium coin cell + F0 + baro sensor + few meg of spi flash -> should last for a year or so
2017-11-16T15:30:53 < Laurenceb> emeryth: sounds accurate and low power /s
2017-11-16T15:30:54 < jpa-> people in netherlands are safe
2017-11-16T15:31:04 < Laurenceb> baro doesnt work in flat countries yeah
2017-11-16T15:31:27 < karlp> or even just flat cities, like lots of US cities
2017-11-16T15:31:48 < jpa-> cities are probably too dense for accurate tracking anyway
2017-11-16T15:32:16 < jpa-> neighbouring streets are easily same elevation, and pedestrian passings etc. mess up timing
2017-11-16T15:32:36 < jpa-> i'll keep buying my spy devices from emeryth and only buy horse trackers from Laurenceb

2017-11-16T15:37:29 < Laurenceb> the tricky bit is matching altitude changes to ground track
2017-11-16T15:37:34 < Laurenceb> a fun problem to solve
2017-11-16T15:46:27 < qyx> an imu would give you a rough estimation too
2017-11-16T15:46:43 < qyx> also you could see if the car is moving
2017-11-16T15:46:52 < qyx> much vibration
2017-11-16T15:47:04 < qyx> full imu and baro would be more practical imho
2017-11-16T15:47:09 < Laurenceb> imu drift would be aweful
2017-11-16T15:47:24 < Laurenceb> I guess pattern recognition of cornering might work

2017-11-16T15:47:37 < qyx> you would correlate with streets
2017-11-16T15:48:07 < qyx> also there are more possibilities
2017-11-16T15:48:13 < qyx> you could track traffic lights

2017-11-16T20:57:51 < englishman> Firefox is ending support for plugins, so Hangouts won’t be able to support video and phone calls in Firefox until Hangouts is updated to resolve the problem. Google is working on a solution that will be available as soon as possible.

2017-11-16T20:58:55 < englishman> upgrdman dma does require a lot of silicon
2017-11-16T20:59:23 < upgrdman> really?
2017-11-16T21:01:21 < jpa-> the memory bus interface does
2017-11-16T21:01:52 < jpa-> i doubt the individual channels in the dma controller require much more than just the registers etc. that are needed for their configuration
2017-11-16T21:02:41 < jpa-> but even that could be significant enough
2017-11-16T21:03:05 < englishman> not just routing but timing
2017-11-16T21:03:15 < englishman> now you have to sync clocks across periph domains

2017-11-16T21:30:30 < englishman> uh
2017-11-16T21:30:37 < englishman> you know antistatic bags are conductive right
2017-11-16T21:32:11 < Thorn> how conductive
2017-11-16T21:32:38 < Thorn> last time I tried to measure one my DMM couldn't see any conductivity
2017-11-16T21:33:14 < jpa-> depends on bag, but rarely enough to matter
2017-11-16T21:33:15 < englishman> how much potential does your DMM output?
2017-11-16T21:33:25 < englishman> conductive enough to conduct away any static electricity
2017-11-16T21:33:55 < englishman> i once fried a computer motherboard on its own static bag, true story
2017-11-16T21:34:46 < Thorn> by turning it on?
2017-11-16T21:35:05 < englishman> it was on yeah
2017-11-16T21:35:39 < upgrdman> heh. i ran an old amd athlon mobo on its antistatic bag for >1yr when i was a kid
2017-11-16T21:35:46 < upgrdman> must have gotten lucky
2017-11-16T21:36:00 < englishman> yeah im pretty sure i've done the same
2017-11-16T21:36:22 < upgrdman> but TBH, i dunno how englishman fucked his mobo that way. what kinda of mobo cant handle >10Meg between any of its pins
2017-11-16T21:36:45 < upgrdman> maybe you had a grain of salt of someshit on the bag
2017-11-16T21:36:50 < englishman> maybe
2017-11-16T21:38:04 < Thorn> ok steps to reproduce
2017-11-16T21:39:50 < Thorn> place a metal box onto the table. put a paper tissue on top of it for insulation. put the pcb onto the tissue
2017-11-16T21:39:52 < Thorn> touch the metal box -> repeated crashes
2017-11-16T21:40:24 < upgrdman> i'd start the usual way: probe your VDD and GND and look for fuckery
2017-11-16T21:40:35 < upgrdman> then move on to your signal lines, etc.
2017-11-16T21:41:53 < upgrdman> oh, and make sure you have stuff like SPI mode config'd right. i remember one time i was using an spi gyro on mode 1 and it would work until i touched the pcb and ever so slightly shifted timings off. turns out i need mode 0 or something (mode 3? forget which.)
2017-11-16T21:43:12 < upgrdman> and htf is it "crashing" ... wrong data received over SPI?
2017-11-16T21:43:14 < Thorn> there is no spi, only j-link and an uart for debugging (disconnecting both does not help)
2017-11-16T21:43:22 < Thorn> reboot
2017-11-16T21:43:37 < englishman> do you have a capacitor on your reset line
2017-11-16T21:43:37 < upgrdman> hmm
2017-11-16T21:43:50 < Thorn> the nrf code is full of APP_ERROR_CHECK() or whatever after every softdevice call which simply reboots
2017-11-16T21:43:50 < upgrdman> ya and even if you do, prove the reset line for fuckery
2017-11-16T21:43:51 < englishman> does it happen if you disconnect jtag
2017-11-16T21:43:55 < Thorn> maybe one of those triggers
2017-11-16T21:44:38 < Thorn> englishman: (1) not sure, it's a module lol, I didn't put one and (2) yes
2017-11-16T21:44:54 < Thorn> btw reset is SWDIO (or SWCLK?) on nrf
2017-11-16T21:45:05 < upgrdman> wat
2017-11-16T21:45:07 < Thorn> which is weird by itself
2017-11-16T21:45:29 < upgrdman> that cant be possible? maybe they mean its software-reset-only?

2017-11-16T21:47:26 < upgrdman> nice solder jizz dust on J15
2017-11-16T21:48:32 < upgrdman> oh, try swapping your jumper wires
2017-11-16T21:48:39 < upgrdman> i've had plenty of fucked one
2017-11-16T21:49:01 < upgrdman> where line only one or two strands were good, and flexing them would cause open circuit
2017-11-16T21:49:14 < upgrdman> because china
2017-11-16T21:50:59 < qyx> yes, those china dupont wires (or how do they call them) are really bad

2017-11-16T22:00:56 < Rickta59> you sure you aren't talking ab out swclk? on 24 ..
2017-11-16T22:01:05 < Rickta59> that is the only pull down i see

2017-11-16T22:03:29 < englishman> sry
2017-11-16T22:03:31 < englishman> but yea
2017-11-16T22:03:56 < Thorn> l0l @ table 29
2017-11-16T22:04:39 < Thorn> you need to hold /reset low for 0.2µs to reset, but if swd is active then it's 100µs
2017-11-16T22:06:40 < Thorn> >... the nRF51822 is entering debug mode, as this only requires SWDIO to be pulled low while SWDCLK is pulled high
2017-11-16T22:06:55 < Thorn> this is why swdclk has a pulldown
2017-11-16T22:07:50 < Thorn> >the nRF52 chip has been designed to avoid this problem by requiring a more complicated start sequence to enter debug mode
2017-11-16T22:10:45 < Thorn> update: if I touch both the gnd and the metal box it doesn't reset
2017-11-16T22:11:22 < Thorn> could be capacitive coupling of line voltage through the body

2017-11-17T00:36:19 < Cracki> (gen)
2017-11-17T00:36:32 < englishman> i think upgrdman's F1 siggen was better
2017-11-17T00:36:33 < Cracki> analog bw 1 MHz, sampling 10 MS/s
2017-11-17T00:36:59 < kakimir> "The bandwidth of an oscilloscope actually indicates the point at which the measured amplitude on an amplitude/frequency chart has decreased by -3dB (or 70.7%) of the original value!"
2017-11-17T00:37:04 < kakimir> https://blog.adafruit.com/2012/01/27/why-oscilloscope-bandwidth-matters/
2017-11-17T00:37:07 < Cracki> perhaps, I'm keen on a handheld scope tho, and the "stm32 based" scopes appear to go up to 1 MS/s only
2017-11-17T00:37:16 < kakimir> so at 1Mhz it's 3dB down
2017-11-17T00:37:19 < Cracki> yes yes analog bw, important to know
2017-11-17T00:37:27 < Cracki> the dso203 has 8 MHz analog bw, 72 MS/s
2017-11-17T00:37:31 < englishman> protip, all signals are analogue
2017-11-17T00:37:44 < kakimir> :)
2017-11-17T00:37:48 < Cracki> protip: say something useful
2017-11-17T00:37:52 < kakimir> interesting insight
2017-11-17T00:38:22 < englishman> googling ds212 returns only synology stuff
2017-11-17T00:38:28 < englishman> what do you want to do with handheld scope
2017-11-17T00:38:39 < englishman> do you require portability
2017-11-17T00:38:41 < Cracki> the afe of the dso203 seems to have been limited more than it needed to be
2017-11-17T00:39:02 < Cracki> I require not having to lug a bench scope to a machine in the field
2017-11-17T00:39:38 < Cracki> some simple scoping, nothing fancy
2017-11-17T00:40:00 < kakimir> I have shitty scope in my uni-t multimeter
2017-11-17T00:40:07 < kakimir> there is problems with trigger
2017-11-17T00:40:17 < kakimir> but it almost always does the job
2017-11-17T00:40:29 < Cracki> I have some old MS-1280 lcd scope, its screen update is horrible
2017-11-17T00:41:08 < kakimir> looks pretty similar you get with uni-t
2017-11-17T00:41:24 < Cracki> I'm really looking for something that can do analog, but mostly does LA work without a laptop
2017-11-17T00:42:28 < Cracki> I find the form factor attractive too. it's not a luggable, it fits in a pocket
2017-11-17T00:42:36 < kakimir> dear god.. there is reset button in the ubiquiti psu
2017-11-17T00:42:46 < Cracki> (would be nice to have an addon for android phones... microusb)
2017-11-17T00:42:54 < kakimir> it remotelly resets that bloddy thing I just lifted 6meters up
2017-11-17T00:43:05 < kakimir> so good
2017-11-17T00:45:52 < Cracki> hm, the ds212 is just stm32f3... the dso203 contains an fpga, so more complex firmware

2017-11-17T03:29:17 < dongs> no but i would pay to see you do that
2017-11-17T03:29:20 < dongs> link to vid anyway
2017-11-17T03:29:35 < upgrdman> dongs, lol nice. damn i cant compete with them :)
2017-11-17T03:30:13 < upgrdman> i would, like, have to do real engineering, if i ever want to make a quality robutt
2017-11-17T03:30:36 < dongs> eh
2017-11-17T03:30:46 < dongs> upgrdman: jap did that robot thing that spins on a pipe
2017-11-17T03:30:49 < dongs> and lands
2017-11-17T03:31:07 < upgrdman> ya saw that
2017-11-17T03:31:09 < jadew> I think the biggest challange is the mechanical part
2017-11-17T03:31:10 < upgrdman> super amazeballs
2017-11-17T03:31:17 < jadew> it has to be fast and precise
2017-11-17T03:31:36 < jadew> well, electro-mechanical
2017-11-17T03:32:14 < upgrdman> i still really want to make a centipede robot. but not one of those over-simplified ones i've seen. one that actually articulates like a centipede
2017-11-17T03:32:16 < jadew> the software is just a bit of math and some feedback loops
2017-11-17T03:32:34 < upgrdman> if i ever buy a laser cutter i'll probably try to make the centipede
2017-11-17T03:33:17 < jadew> now all they have to do is put a vagina on that thing and they'll have a best seller in japan
2017-11-17T03:33:20 < upgrdman> at least thought robot should reuqire much technical ability. just gets the mechanics right.
2017-11-17T03:33:40 < upgrdman> at least that robot shouldn't reuqire much technical ability. just gets the mechanics right.
2017-11-17T03:35:04 < upgrdman> only drawback is i would HAVE TO use a retarduino in order to get muh ad revenue
2017-11-17T03:35:20 < upgrdman> maybe an ESP8266 for the RF for moar ad revenue
2017-11-17T03:37:18 < dongs> fuckign japs

2017-11-17T03:54:46 < Ultrasauce> i am all for gratuitous empiricism but really...
2017-11-17T03:55:20 < tpw_rules> the frequency drift might be problematic
2017-11-17T03:55:36 < tpw_rules> but that's entirely app-specific
2017-11-17T03:55:40 < tpw_rules> the chip can do -40

2017-11-17T03:56:57 < tpw_rules> no it won't die
2017-11-17T03:57:34 < tpw_rules> but like i once had a pair of 433mhz dongers i used for a weather station and once it got very cold outside, the frequency drifted and it couldn't talk to the receiver inside
2017-11-17T03:58:29 < tpw_rules> so as long as all your shit can tolerate like 5% clock drift you should be good

2017-11-17T11:50:35 < ohsix> lul adam is 'hyfy' after drinking spoiled milk on the last episode of adam ruins everything
2017-11-17T11:52:48 < karlp> hyfy?
2017-11-17T12:04:35 < ohsix> yea, used to be a meme among stoners
2017-11-17T12:06:26 < zyp> haha, this is bullshit: https://e2e.ti.com/support/microcontrollers/hercules/f/312/p/505678/1833150#1833150
2017-11-17T12:08:32 < zyp> context: TI hercules has a jtag protection thing based on a key stored in OTP, default key is mostly ones since OTP can only be written to 0
2017-11-17T12:11:13 < zyp> now, the flash (which OTP is part of) has ECC, calculated over 64 bit words, making 72-bit entries
2017-11-17T12:11:32 < zyp> and the ECC bytes for the key is naturally already calculated
2017-11-17T12:11:44 < zyp> and that can't be erased either
2017-11-17T12:13:18 < zyp> so for a new key to be valid, not only must the new key keep the zero bits from the old key, the new key must also have an ECC value that keeps the zero bits from the old key's ECC
2017-11-17T12:13:56 < karlp> heh, hilarious
2017-11-17T12:14:20 < jpa-> the unlock code being 128 bits long, there would be enough entropy though
2017-11-17T12:14:45 < jpa-> but then they choose to provide an .exe that uses srand() (16 or 32 bits of entropy) based on PC time...
2017-11-17T12:15:51 < qyx> I am curious how secure is it
2017-11-17T12:17:40 < zyp> jpa-, yeah, that's true
2017-11-17T12:18:45 < zyp> the default ECC is ED C0, which out of 16 bits has 8 zeroes, throwing away 8 bits of entropy
2017-11-17T12:18:56 < zyp> and the default key has five zeroes
2017-11-17T12:19:12 < karlp> security by onion
2017-11-17T12:19:20 < zyp> leaving you with a 2^115 keyspace, that's not too bad
2017-11-17T12:19:27 < karlp> it doesn't matter if it's soft and easy to cut, as long as there's lots of layers of it.
2017-11-17T12:19:50 < jpa-> karlp: you forgot important part: every layer is so stupid it makes you cry
2017-11-17T12:20:19 < zyp> there should be about 2^107 keys that matches the original ECC so you don't even have to rewrite it :p
2017-11-17T12:21:58 < zyp> given that each half's ECC is independent, brute forcing a valid ECC should take no time at all
2017-11-17T12:22:25 < zyp> still stupid
2017-11-17T12:23:07 < zyp> anyway, it also answers what I were actually wondering about
2017-11-17T12:23:53 < zyp> since ECC is calculated on 64-bit words and can't be rewritten, I'll have to write 64 bits of OTP at a time

2017-11-17T12:41:09 < jadew> it has some awesome features too
2017-11-17T12:41:15 < jadew> like added harmonic content

2017-11-17T15:58:58 < jadew> but that sounds like a pain in the ass too
2017-11-17T15:59:41 < jadew> also, I don't want 2-3 years from now to have to deal with the same shit again
2017-11-17T16:00:33 < jadew> I'll just install quattro and use an altera part
2017-11-17T16:15:04 < aandrew> whoa whoa whoa
2017-11-17T16:15:10 < aandrew> < dongs> stop wasting time with win10
2017-11-17T16:15:14 < dongs> it was never about xilinx was it
2017-11-17T16:15:17 < aandrew> do my eyes deceive me?
2017-11-17T16:15:19 < dongs> it was always about you're gonna use altera
2017-11-17T16:15:21 < dongs> and you just wanted to blog
2017-11-17T16:15:29 < dongs> aandrew: no im talking about him trying to waste time running ISE under win120
2017-11-17T16:15:40 < jadew> dongs, no, I want to use xilinx
2017-11-17T16:15:47 < jadew> I have a bunch of xilinx tools and dev boards
2017-11-17T16:15:50 < dongs> then shut the fuck up, install win7 in VM and start working
2017-11-17T16:15:53 < dongs> dont be a faggot
2017-11-17T16:16:01 < dongs> less autism, more work
2017-11-17T16:17:45 < aandrew> hah
2017-11-17T16:18:05 < aandrew> I use win7 VMs for anything windows that i have to do. it's the best way to run windows. locked away in a VM away from real HW
2017-11-17T16:18:31 < aandrew> the only thing I have not found a good solution for is ESXi USB forwarding. USB4RDP and others do a marginal job at best
2017-11-17T16:18:44 < aandrew> using VMware Fusion on my workstation is flawless though
2017-11-17T16:18:59 < aandrew> I still can't believe how great Altium works over RDP
2017-11-17T16:19:25 < aandrew> although I've heard rumour that Altium18 wants significantly beefier graphics HW
2017-11-17T16:27:49 < dongs> good
2017-11-17T16:28:00 < dongs> maybe its rewritten in C instead of delphi, too
2017-11-17T16:28:22 < tpw_rules> tcl for life
2017-11-17T16:29:15 < aandrew> yeah right
2017-11-17T16:29:39 < aandrew> although they did say it's multithreaded and 64b support now. Is such a thing possible in Delphi now?
2017-11-17T16:29:48 < tpw_rules> i'm thankful all this shit missed the java boat
2017-11-17T16:29:49 < aandrew> I can't imagine the amount of work that was to port away
2017-11-17T16:29:51 < dongs> 64bit about time
2017-11-17T16:30:04 < dongs> tpw_rules: FPGA tools didnt miss the java boat
2017-11-17T16:30:08 < dongs> they got fully onboard.
2017-11-17T16:30:12 < dongs> xilinx ships 3 copies of jvm
2017-11-17T16:30:12 < tpw_rules> quartus did
2017-11-17T16:30:15 < dongs> with each install of ISE
2017-11-17T16:30:20 < tpw_rules> it's all tcl
2017-11-17T16:30:23 < dongs> beacuse 1 copy wasnt enough
2017-11-17T16:30:24 < dongs> lol, tcl
2017-11-17T16:30:29 < dongs> tcl is inISE too
2017-11-17T16:30:33 < dongs> fucking gross.
2017-11-17T16:30:34 < tpw_rules> actually i take that back all the nios stuff is java
2017-11-17T16:30:41 < tpw_rules> it ships eclipse

2017-11-17T17:15:45 < jadew> looks both efficient and eco friendly
2017-11-17T17:16:54 < BrainDamage> if you put the generator in the car's trunk, does it make it an internal combustion car again?
2017-11-17T17:17:27 < englishman> hey you invented PHEV
2017-11-17T17:20:08 < jadew> BrainDamage, it won't fit in the trunk, you need that trailer to fit both the generator and the gas
2017-11-17T17:21:10 < BrainDamage> you can push down the seats, like most cars
2017-11-17T17:21:20 < jadew> ah, good point
2017-11-17T17:22:15 < jadew> I guess that wouldn't be necessary for the ones that also have a front trunk
2017-11-17T17:22:19 < jadew> you can put the engine there
2017-11-17T17:22:22 < jadew> and the gas in the back
2017-11-17T17:23:17 < jadew> then people will wonder why your tesla sounds like a trabant
2017-11-17T17:23:44 < aandrew> what is a trabant
2017-11-17T17:23:57 < jadew> a cardboard car
2017-11-17T17:24:03 < jadew> top german quality
2017-11-17T17:24:54 < jadew> sounds like a chainsaw

2017-11-17T17:27:29 < jadew> my grandpa had one, he always had to work on it
2017-11-17T17:27:39 < jadew> he actually bought another one for spare parts
2017-11-17T17:27:48 < aandrew> I thought you romanians were all about the dacia
2017-11-17T17:28:08 < jadew> we had a bit of variation
2017-11-17T17:28:20 < jadew> trabants, some VWs
2017-11-17T17:30:48 < jadew> funny thing about the trabant, is that in the car's manual it says that all trabant owners have to salute themselves when they pass by each other
2017-11-17T17:30:56 < jadew> and they did (probably still do)
2017-11-17T17:31:30 < aandrew> hahaha
2017-11-17T17:31:44 < aandrew> kind of like that handlebar wave motorcyclists do around here
2017-11-17T17:33:27 < jadew> Q: why is a trabant not moving after the traffic light turned green. A: it's stuck into a gum.
2017-11-17T17:33:39 < jadew> we have lots of jokes about that car
2017-11-17T17:34:15 < jadew> and kids used to tease me because my grandpa had one
2017-11-17T17:35:31 < jadew> they made a rhyme in which they were calling my grandparents by their names and they were having sex in the trabant

2017-11-17T17:41:01 < PaulFertser> jadew: I wonder why it was still produced given it's so much inferior to soviet cars such as lada and even moskvich?
2017-11-17T17:41:32 < jadew> I don't know, maybe it was cheaper?

2017-11-17T17:56:44 < kakimir> when I was test driving model s it was really hard to do everything with that ipad

2017-11-17T17:58:01 < englishman> years of unprofitability
2017-11-17T17:58:05 < englishman> highly leveraged

2017-11-17T17:58:29 < englishman> large additional investment needed to enter chinese market, no chinese partners
2017-11-17T17:58:42 < englishman> poor assembly line performance
2017-11-17T17:58:48 < englishman> looming fleet of cars coming out of warranty

2017-11-17T18:00:52 < dongs> ill never buy a tesla as long as they have that fucking ipad bolted in there
2017-11-17T18:01:26 < karlp> what doyou mean by "unfunded product lines" ?
2017-11-17T18:02:01 < englishman> pickup, semi truck, model Y are unfunded
2017-11-17T18:02:11 < englishman> as in, they need to raise capital to fund their design and production
2017-11-17T18:02:29 < englishman> but they already added $1.8b in debt this quarter to pay for model 3 production line
2017-11-17T18:02:34 < karlp> assembly lien peformance, do you mean there that they get a very low yield on bodies attempted to assemble? like late production failures that get scrapped, rather than everything coming off the line being good?
2017-11-17T18:02:44 < PaulFertser> jadew: hm, indeed, the trabant wikipedia article says it was extremely cheap, about the same as a motorbike with a sidecar, 2x less than a "real car".
2017-11-17T18:02:44 < karlp> yeah, semi truck looks dumb as fuck,
2017-11-17T18:03:20 < jadew> PaulFertser, my grandpa had a motorbike with a sidecar too
2017-11-17T18:03:44 < PaulFertser> jadew: what make/model?
2017-11-17T18:03:53 < englishman> karlp, with S and X they purchased a toyota assembly line. with 3 they are attempting to start up a new assembly line, but it is years behind schedule. they are telling their parts suppliers to slow down
2017-11-17T18:03:53 < jadew> I don't know, he sold it before I was born
2017-11-17T18:04:12 < englishman> well trabant was basically a motorcycle
2017-11-17T18:06:27 < PaulFertser> englishman: it was front-wheel drive, and I guess the transmission wasn't motorbike-style either.
2017-11-17T18:06:48 < englishman> i dono about the trans. but i was thinking of the reserve fuel tank lol
2017-11-17T18:07:14 < englishman> i'm not ripping on trabi at all. it is one of my favourite cars
2017-11-17T18:07:35 < PaulFertser> Was it literally a reserve fuel tank or just a special valve as on motorbikes?
2017-11-17T18:08:24 < englishman> afaik, like a moto, that draws from further down the tank
2017-11-17T18:08:57 < PaulFertser> Heh, that's a funny detail but it doesn't put it much closer to a motorbike imho.

2017-11-17T19:29:16 < kakimir> jadew: should I open the drive second time and blow in with some CFC air spray to remove dusts?
2017-11-17T19:29:28 < jadew> kakimir, no
2017-11-17T19:29:44 < jadew> did you leave it dusty?
2017-11-17T19:30:03 < jadew> most dust will blow off to the sides
2017-11-17T19:30:10 < jadew> once the disk starts spinning
2017-11-17T19:30:47 < jadew> and the reading head doesn't go in until the disk is spinning at full speed
2017-11-17T19:30:59 < kakimir> yes
2017-11-17T19:31:08 < jadew> because it floats on the air that's flowing because of that rotation
2017-11-17T19:31:15 < kakimir> there is actually air filter inside the drive
2017-11-17T19:31:30 < jadew> so the odds of dust remaining on the disk are small
2017-11-17T19:31:41 < kakimir> yes
2017-11-17T19:31:57 < kakimir> big dust at least
2017-11-17T19:32:03 < kakimir> some micro dust idk

2017-11-17T19:46:14 < kakimir> I suspect pcb hit metal frame of computer or so

2017-11-17T19:47:29 < jadew> and see if you get the expected voltages
2017-11-17T19:47:46 < kakimir> there is no danger in doing that?

2017-11-17T19:49:21 < kakimir> another option is that disc fell at some point - not that I knew it did - but possible

2017-11-17T20:07:20 < kakimir> if it starts working magically or something
2017-11-17T20:07:35 < kakimir> I mean without changing bios
2017-11-17T20:07:54 < kakimir> and how important is that bios?
2017-11-17T20:07:56 < kakimir> totally?
2017-11-17T20:08:00 < jadew> I don't know, that's the thing
2017-11-17T20:08:23 < jadew> if it can calibrate itself, it will probably work, if it has some custom settings for each disk, it won't work
2017-11-17T20:08:30 < jadew> the easiest way to find out is to try
2017-11-17T20:08:40 < jadew> get a disk off of ebay and see how it goes, can't be more than $20
2017-11-17T20:09:10 < kakimir> $30 buy it now
2017-11-17T20:09:35 < kakimir> I wonder if calibration data was that important even when this drive was made

2017-11-17T22:14:50 < jpa-> jadew: didn't even try, i just cut it off to save the pcb and rest of parts
2017-11-17T22:15:26 < jadew> isn't it easier to desolder it?
2017-11-17T22:15:55 < jpa-> lqfp100? nope
2017-11-17T22:16:02 < jpa-> even with hot air it is pretty annoying
2017-11-17T22:24:05 < Cracki> what options are there besides cutting it off and cleaning up the solder joints with dangling legs, or heat gun?
2017-11-17T22:24:41 < jadew> heating it up and removing it with a tweezers
2017-11-17T22:24:59 < jpa-> chipquick (low melting point solder) works also
2017-11-17T22:25:05 < Cracki> ah right that stuff

2017-11-17T22:25:37 < Cracki> lol hot plate, what's next, flammenwerfer?
2017-11-17T22:25:47 < jadew> seriously
2017-11-17T22:26:05 < jadew> you preheat the board then you just apply a bit of heat with the heat gun and you remove it
2017-11-17T22:26:34 < Cracki> I saw some industrial stuff that used well timed laser to solder joints. might be possible to heat all the joints for desoldering too, if the laser can be x/y deflected?
2017-11-17T22:26:44 < Cracki> hmhm
2017-11-17T22:27:17 < jadew> they were using the laser to solder through hole stuff IIRC
2017-11-17T22:28:01 < jadew> probably as a ploy to drive 80% of the chinese population out of work

2017-11-17T23:35:40 < ohsix> running perf record on the pi to see wtf dnf is doing that's so slow; and somehow it's recording 10 times the information the same job takes on my laptop

2017-11-17T23:37:37 < ohsix> would be funny if the tracing stuff on the pi or on arm was better than x86
2017-11-17T23:38:14 < englishman> beep andrew
2017-11-17T23:38:20 < englishman> is there *any* good accounting soft
2017-11-17T23:38:23 < stvn> beep
2017-11-17T23:38:31 < stvn> yeah niggerbooks
2017-11-17T23:38:32 < englishman> i feel like i'm doing basic bitch shit and every soft is failing hard
2017-11-17T23:38:36 < stvn> i mean quickbooks
2017-11-17T23:38:41 < ohsix> gnucash
2017-11-17T23:38:44 < englishman> trying that now
2017-11-17T23:38:55 < englishman> $40/month and you cannot rename your tax groups
2017-11-17T23:39:14 < ohsix> there's a fairly serious one that's out and does lots of stuff, but i expect that it will be on confusing feature parity with quickbooks and shit
2017-11-17T23:39:30 < englishman> tried sage one but it doesnt support foreign currency bank accounts
2017-11-17T23:39:46 < ohsix> foreign or just non-primary
2017-11-17T23:40:04 < ohsix> hm
2017-11-17T23:40:50 < ohsix> lul shit i should probably have been using gnucash for invoice tracking
2017-11-17T23:41:07 < ohsix> englishman: it does multiple currencies hehe
2017-11-17T23:43:56 < ohsix> AHH erp was the stuff i was thinking of, that also includes accounting
2017-11-17T23:45:03 < ohsix> others in fedora package repos http://homebank.free.fr/en/ http://ledger-cli.org/
2017-11-17T23:45:11 < ohsix> rest are ERP and only some of the erp packages do accounting
2017-11-17T23:45:45 < ohsix> Ledger is 100% currency-agnostic. You can store multiple currencies in any account, convert between them, or even pay in one currency and receive change in another.

2017-11-17T23:49:58 < karlp> jpa-: I'm running kicad 4.0.6, so only one . behind latest, am I meant to be going and installing all these .pretty repos locally or something? I feel like there's shitttons of footprints that aren't available to me
2017-11-17T23:50:06 < ohsix> it's one of those areas where lobbyists are there mostly to fuck shit up and make stuff hard to make their services relevant

2017-11-18T00:21:17 < englishman> lol SAP uses flash
2017-11-18T00:21:37 < stvn> wut is sap
2017-11-18T00:21:57 < englishman> more pro accounting soft
2017-11-18T00:22:06 < stvn> some kind of niggery
2017-11-18T00:22:29 < stvn> why is pro software so shit
2017-11-18T00:24:00 < zyp> because people are making it to get paid for it, not to actually use it
2017-11-18T00:24:25 < stvn> sounds about right
2017-11-18T00:24:26 < englishman> i cannot believe the absolute faggotry in this $40/month soft
2017-11-18T00:24:41 < englishman> the online one does tax totally different from the desktop one too
2017-11-18T00:25:48 < stvn> of course
2017-11-18T00:26:05 < zyp> when people talk about taxes, you make it sound like a big ordeal
2017-11-18T00:26:11 < englishman> it isn't
2017-11-18T00:26:14 < englishman> it's fucking easy
2017-11-18T00:26:18 < zyp> yeah?
2017-11-18T00:26:35 < englishman> this soft makes it nontrivial
2017-11-18T00:26:39 < stvn> http://ieeexplore.ieee.org/document/1218272/?reload=true
2017-11-18T00:26:41 < zyp> haha
2017-11-18T00:26:51 < stvn> the software
2017-11-18T00:26:55 < englishman> yeah super easy, especially sales tax
2017-11-18T00:26:56 < stvn> is infected with ice bugs
2017-11-18T00:27:40 < zyp> this is company tax?
2017-11-18T00:27:44 < englishman> yeah
2017-11-18T00:28:15 < zyp> makes sense, company tax we even have to do something about here in norway
2017-11-18T00:28:33 < englishman> this shitty quickbooks soft does not let you modify/rename/delete tax groups after you create them
2017-11-18T00:28:43 < zyp> haha
2017-11-18T00:28:46 < englishman> seriously
2017-11-18T00:29:01 < englishman> $40/month
2017-11-18T00:29:18 < englishman> plus the name of the tax group appears on POs

2017-11-18T00:29:36 < sync> lel
2017-11-18T00:29:41 < jadew> why are you using that one?
2017-11-18T00:30:11 < englishman> so now because i have a bunch of nonworking tax groups i can no longer modify or rename, i have to see TAXCODE (ITCs/ maybethisoneworksIDONO!!!) on every line of every PO and invoice
2017-11-18T00:30:46 < zyp> awesome
2017-11-18T00:31:00 < englishman> the other one i tried was sageone jadew
2017-11-18T00:31:06 < englishman> but it does not support foreign currency bank accounts
2017-11-18T00:31:16 < englishman> another "gotcha"
2017-11-18T00:31:34 < karlp> never meant anyone happy with their accountancyh software
2017-11-18T00:31:50 < karlp> just people at various stages of, "I know how to work around it enough to make it through my day"
2017-11-18T00:32:12 < jadew> and it's $40/mo?
2017-11-18T00:32:17 < englishman> yes
2017-11-18T00:32:18 < jadew> why is there no competition?
2017-11-18T00:32:25 < zyp> the accounting stuff I use for my business is decent enough
2017-11-18T00:32:52 < zyp> except the company got bought up and the product cancelled, and now they want me over on another product
2017-11-18T00:33:08 < englishman> just found Zoho
2017-11-18T00:33:10 < englishman> will try that
2017-11-18T00:33:29 < Cracki> lol they removed hitler quotes from freebsd fortune https://twitter.com/Sh1bumi/status/931563255222407168
2017-11-18T00:33:46 < Cracki> (and later, removed all quotes, leaving nothing of humor)
2017-11-18T00:34:57 < zyp> hmm, the thing I'm using is $24/mo, but paid annually
2017-11-18T00:36:39 < zyp> it's kinda overkill, because all I'm getting out of it are two numbers for my tax report: total income, total expenses
2017-11-18T00:36:55 < englishman> personal business?
2017-11-18T00:36:57 < englishman> or Inc.
2017-11-18T00:37:00 < zyp> personal
2017-11-18T00:37:04 < englishman> personal business was wayyy easier
2017-11-18T00:37:08 < englishman> yeah same
2017-11-18T00:37:10 < englishman> just needed those
2017-11-18T00:37:19 < zyp> yeah, I'm not even over the limit for being subject to VAT
2017-11-18T00:37:19 < englishman> with Inc. there are 200+ lines
2017-11-18T00:37:39 < englishman> which is to my benefit really as things like manufacturing are taxed way lower
2017-11-18T00:37:52 < englishman> and i can claim all these ITCs
2017-11-18T00:38:00 < zyp> so I just report income and expenses, and the difference gets folded directly into my personal income tax
2017-11-18T00:38:53 < zyp> only reason I'm paying for an accounting system at all is because then I don't have to worry about whether I'm compliant with record keeping regulations
2017-11-18T00:39:14 < zyp> in case tax authority ends up wanting to audit me
2017-11-18T00:39:50 < zyp> which they very well could
2017-11-18T00:40:09 < zyp> last year I reported zero income and $2600 in expenses :p
2017-11-18T00:40:36 < zyp> I figure that could raise some flags
2017-11-18T00:41:27 < sync> I just used an excel sheet
2017-11-18T00:41:55 < sync> but yeah it sucked
2017-11-18T00:41:57 < jadew> I have an accountant
2017-11-18T00:42:08 < zyp> I sent no invoices last year, most of the expenses were for a project that got delivered in february this year
2017-11-18T00:42:19 < zyp> so the income comes this year
2017-11-18T00:42:29 < jadew> my company is also on -
2017-11-18T00:42:38 < jadew> the accountant being a big part of that minus
2017-11-18T00:42:43 < zyp> haha
2017-11-18T00:42:53 < zyp> paying an accountant doesn't seem worth it
2017-11-18T00:43:08 < jadew> well, he costs the same as your programs
2017-11-18T00:43:18 < jadew> about 25-30/mo
2017-11-18T00:43:47 < zyp> pretty sure an accountant in norway would cost more
2017-11-18T00:44:09 < englishman> im about to skeet all over quickbooks
2017-11-18T00:44:14 < jadew> that's the starting price, when you have very little activity (or none, like in my case)
2017-11-18T00:44:17 < englishman> zoho is gr8 so far
2017-11-18T00:48:26 < invzim> I would like a good online accouting system for .NO
2017-11-18T00:49:03 < zyp> invzim, I'm being pushed to tripletex
2017-11-18T00:49:08 < invzim> looked at fiken.no, but seemed very meh when most activity would be to/from abroad

2017-11-18T08:45:05 < ohsix> here's what happened today: an audiophile had me change the color of an led in his preamp power supply, which was huge
2017-11-18T08:45:28 < ohsix> tried to ask him some stuff and if he was on the 'stereophile' side of things, and what he thought of the cables and stuff
2017-11-18T08:45:37 < ohsix> he was very cables matter
2017-11-18T08:46:06 < ohsix> and by the time i stopped he was offering that i come listen to it while he switches stuff around, and he handed me his card, which reads as follows
2017-11-18T08:46:13 < ohsix> "acupuncture and chinese herbal medicine"
2017-11-18T08:46:30 < ohsix> all around pretty funny, but was too distracted to enjoy it
2017-11-18T08:47:47 < ohsix> and the arduino thing was interesting, was a custom touch sensor thing and they wanted regular stuff on test pads, not something dum
2017-11-18T08:48:29 < ohsix> dudes title is "diplomate chinese herbology ac om"

2017-11-18T10:15:21 < PaulFertser> ohsix: what about python interactive prompt and pyusb?
2017-11-18T10:15:51 < ohsix> sure
2017-11-18T10:16:08 < ohsix> just wanted to do one thing. it looks like i can hijack some stuff usb_modeswitch incidentally does, tho
2017-11-18T10:16:46 < ohsix> time to storm the internet with this awesome solution that doesn't involve compiling something that just does an ioctl!!11

2017-11-18T10:21:08 < ohsix> R is 'reset when done', but it lets you do no operation
2017-11-18T10:21:23 < ohsix> hm doing it the second time killed the pi
2017-11-18T10:24:44 < PaulFertser> I once tried to fully understand the capabilities that rpi has regarding powering its usb ports. What a mess! Apparently they can be controlled but in a weird way, and somehow it leads to instability after N cycles. So better use a proper external hub, heh.
2017-11-18T10:27:05 < ohsix> it has worse problems than that, it suxbad
2017-11-18T10:43:09 < PaulFertser> In what area?

2017-11-18T13:16:03 < PaulFertser> dongs: to power-cycle a usb peripheral of course. A legit usecase imho.
2017-11-18T13:16:15 < dongs> no shit, b ut good luck finding a hub that actally does this
2017-11-18T13:16:25 < dongs> i have yet to see one that wasnt some industrial shit that was $$$
2017-11-18T13:16:59 < PaulFertser> With your skills you can easily build one yourself, as most usb hub ICs actually support that.

2017-11-18T13:17:16 < dongs> PaulFertser: that was my point

2017-11-18T13:17:38 < PaulFertser> dongs: ok, and after having built such a hub, how would you control it from windows?
2017-11-18T13:18:02 < PaulFertser> Or would you rather embed a dedicated microcontroller with custom hid protocol to do that?
2017-11-18T13:19:02 < dongs> ive seen shit to do it before, but im not gonna waste my time looking for it now

2017-11-18T18:29:09 < invzim> got the side wheel tied mapped change layer, top button mapped to place, one to backspace for ripup, change layers with a click+scroll etc
2017-11-18T18:29:35 < dongs> ive looked at that actually, i have side buttons on my M560 to change layer
2017-11-18T18:29:37 < dongs> does wheel work betteR?
2017-11-18T18:29:51 < dongs> once i saw it was wheel iw as like meh
2017-11-18T18:30:33 < invzim> the one thing I hate about it is that the 'thumb' buttons are hard to reach
2017-11-18T18:30:37 < invzim> takes a lot of getting used to
2017-11-18T18:31:04 < invzim> hm no, change layer is one of the thumb buttons+normal scroll wheel
2017-11-18T18:31:12 < invzim> don't think I managed to use the side-scroll for anything
2017-11-18T18:31:35 < dongs> i just have the buttons mapped to - +
2017-11-18T18:31:41 < dongs> which switches layers
2017-11-18T18:31:46 < dongs> how would that work with scroll?

2017-11-18T18:33:29 < aandrew> I never went big on superconfiguration of my workstation
2017-11-18T18:33:34 < aandrew> no special hotkeys, etc.
2017-11-18T18:34:04 < invzim> thumb 1=CTRL+SHIFT, thumb2=backspace, top button P, wheel button enter
2017-11-18T18:34:13 < aandrew> the only thing I do do on my mac laptop is run slate and have ctrl-alt-option [ and ] grab the current window and maximize it on monitor 1 or 2
2017-11-18T18:34:41 < aandrew> for altium specifically it's all keyboard accelerators
2017-11-18T18:34:53 < aandrew> pv, ems, pt, etc
2017-11-18T18:35:25 < aandrew> I do wish there were better keys mapped for layer changes, + and - are far away, keyboardically-speaking
2017-11-18T18:36:12 < invzim> thus the binding on the mx master :)
2017-11-18T18:36:22 < invzim> no control+shift

2017-11-18T18:46:05 < branjb> well
2017-11-18T18:46:24 < branjb> i need one, have a cnc router, and thanksgiving is fucking the mail
2017-11-18T18:46:37 < branjb> dunno how shitty it would turn out
2017-11-18T18:47:13 < fest> I use lasercutter at local hackerspace for one-off stencils
2017-11-18T18:47:36 < fest> engraved craft paper (a bit thicker than regular, plastic-y feel)
2017-11-18T18:47:41 < branjb> lol local hackerspace shut down 3 days ago http://www.azfamily.com/story/36855896/techshop-suddenly-shuts-down-in-chandler
2017-11-18T18:48:21 < Rickta59> why funny?
2017-11-18T18:48:34 < branjb> because 4 days ago i would have no issue getting a stencil
2017-11-18T18:48:37 < branjb> for above reason
2017-11-18T18:48:40 < Rickta59> ah
2017-11-18T18:49:00 < branjb> but once again procrastination pays off
2017-11-18T18:50:54 < sync> "suddenly"
2017-11-18T18:51:25 < Rickta59> i wonder if they had a special last week on memberships
2017-11-18T18:51:58 < branjb> the chandler one was pretty legit
2017-11-18T18:52:01 < branjb> they had 5 axis CNC
2017-11-18T18:52:05 < branjb> and waterjet
2017-11-18T18:52:40 < Rickta59> there was one 3 hrs from me, I went and checked it out, had I lived closer I would have joined
2017-11-18T18:53:00 < Rickta59> they shut down a couple of years ago I think
2017-11-18T18:53:23 < branjb> it's a terrible business model
2017-11-18T18:53:52 < Rickta59> yeah I though I could do one of those and then just did some napkin numbers and said .. this is never going to work
2017-11-18T18:54:34 < branjb> better to just buy shit and put it in your garage
2017-11-18T18:54:37 < branjb> then don't have to share
2017-11-18T18:54:40 < branjb> and doesn't go bankrupt
2017-11-18T18:55:17 < Rickta59> so i guess you will run down to the local laser shop and buy one? :)
2017-11-18T18:55:50 < branjb> i don't do enough laser shit to justify it
2017-11-18T19:08:05 < dongs> good thing make:r spaces are dying
2017-11-18T19:08:06 < jadew> lol @ branjb's link: "It’s completely devastating. Literally, people are crying," said member David Kern who estimates at least 500 people are affected.
2017-11-18T19:08:09 < dongs> fucking waste of space
2017-11-18T19:08:12 < jadew> what was so important about that hacker space?
2017-11-18T19:08:20 < dongs> it was full of hipster faggots
2017-11-18T19:08:30 < dongs> who , if left unchecked, would produce juicero 2.0
2017-11-18T19:08:45 < dongs> amirite or amirite
2017-11-18T19:09:51 < jadew> the idea of shared devices doesn't sound bad tho, like if you could get together with some people to buy a decent CNC, laser cutter, etc, that wouldn't be a bad deal
2017-11-18T19:10:05 < jadew> but not having it open to everyone, just for those who pitched in

2017-11-18T19:37:38 < aandrew> I really like the idea of hackerspaces. the one local to me (kwartzlab) is pretty decent, but what stops me from joining is both lack of time but also the environment around hackerspaces. Like dongs said: mostly hipsters and people who like to be social about their hobbies
2017-11-18T19:38:52 < aandrew> I build out my own lab because if I want to go work at 3am I can go there and not have to worry about some gumby who wants to chat. "oh hey, whatre you building? oh yeah that's cool, why are you building it that way? my cousin's stepsister's husband drove truck for 30 years and he knows all about 45 degree welds using tungsten. I should hook you guys up, you'd like him. real nice guy"
2017-11-18T19:38:53 < zyp> yeah? isn't the social part the point?
2017-11-18T19:39:09 < Steffanx> You mean TempleOS aandrew
2017-11-18T19:39:18 < aandrew> oh fuck yes I meant templeos
2017-11-18T19:40:16 < aandrew> the social part is exactly what i don't want. if I want to go take a class on using a piece of equipment, ok, great. sign me up, I'll be social for that. but then I want to work without chatter
2017-11-18T19:40:26 < Steffanx> Lol, sounds like you and ohsix would get along
2017-11-18T19:40:30 < Steffanx> *not*
2017-11-18T19:41:52 < zyp> so what part of the idea is it that you like then?
2017-11-18T19:41:59 < aandrew> I can stand ohsix here, as long as he's not asking for praise about his drawbot UI
2017-11-18T19:42:29 < Steffanx> that is rob235 lolz
2017-11-18T19:42:33 < aandrew> zyp: having the equipment, properly maintained in one space. having documentation on procedures and so on. having industrial space leased etc
2017-11-18T19:42:42 < aandrew> oh I get all our autists mixed up
2017-11-18T19:42:51 < zyp> sounds like you'd like the one nearby here then
2017-11-18T19:42:52 < Steffanx> i blame your age
2017-11-18T19:43:07 < aandrew> I am getting up there
2017-11-18T19:43:23 < zyp> there's a hackerspace in the neighboring city, but it sounds more like a workshop for rent and less of a social hangout
2017-11-18T19:43:36 < zyp> fairly expensive though
2017-11-18T19:43:54 < zyp> I've never been there, doesn't sound much interesting to me
2017-11-18T19:44:07 < Steffanx> All you need is ##stm32
2017-11-18T19:44:13 < aandrew> meh I'm getting there on my own
2017-11-18T19:44:13 < BrainDamage> do you guys have the same social etiquette of finnish people with the 2m personal space? if so, i guess that'd help
2017-11-18T19:44:25 < zyp> haha
2017-11-18T19:44:57 < zyp> speaking of finnish people, jpa- took me to his hackerspace when I visited, seemed nice
2017-11-18T19:45:05 < jpa-> aandrew: yeah, you want a techshop style thing then
2017-11-18T19:45:15 < aandrew> got the welder and the mill, got a prusia i2 or whatever 3d printer that I just have to finish up. got all the electronics shit of course. I need to build some workbenches and get a little lathe, and then dick around with CNCing the mill
2017-11-18T19:45:27 < jpa-> if the hackerspaces around here are representative, "well maintained, documentation on procedures" etc. doesn't apply :P
2017-11-18T19:45:39 < aandrew> BrainDamage: haha
2017-11-18T19:46:20 < aandrew> I guess it's the same thing about ham radio when i was a kid. lots of guys hanging around chatting which is fun and all, but you can't get anything done and if I'm just hanging around I would rather do it online here so I can still work
2017-11-18T19:46:31 < aandrew> it's easy and not even rude to come in and drop out of social contexts online
2017-11-18T19:46:33 < jpa-> https://images-cdn.9gag.com/photo/arKOZBK_700b.jpg yeah, this is how it works
2017-11-18T19:47:32 < jpa-> though atleast here if you want a quiet moment at the space, just go there outside the twice-a-week gatherings and it is pretty much empty, or if there is someone else there they also want to do their own thing
2017-11-18T19:47:46 < zyp> https://pics.me.me/in-norway-we-have-this-thing-called-personal-space-19260420.png
2017-11-18T19:48:07 < aandrew> yeah I might be overstating the numpties at hackerspaces, but I don't want to pay my dues and look forward to it and end up disappointed
2017-11-18T19:48:38 < jpa-> what cost is there to trying it out?
2017-11-18T19:49:21 < fest> jpa-: like this: https://imgur.com/a/Vplbj ?
2017-11-18T19:50:02 < jpa-> fest: not that bad, but we have atleast 3 3d-printers and none of them work :P
2017-11-18T19:50:28 < fest> (somebody had a week long last-minute build for exhibition)
2017-11-18T19:51:13 < fest> jpa-: hehe, for the last two years we had 4, of which two were mostly working
2017-11-18T19:51:59 < jpa-> we had 4 also but a few months back they decided to disassemble the least-likely-to-ever-work for parts :P
2017-11-18T19:55:56 < aandrew> my local library has 3d printers available. I think I'd rather use those
2017-11-18T19:57:06 < branjb> jadew: that's exactly it, that hackrspace was full of unemployed people with macbooks who would come in as soon as it opened at 6am and stay till it closed at midnight, mostly just sitting around taking up space
2017-11-18T19:57:25 < zyp> haha
2017-11-18T19:58:13 < jadew> branjb, just finished reading what you guys were talking about
2017-11-18T19:58:35 < jadew> branjb, yeah, it's not something I'd enjoy
2017-11-18T19:58:43 < jadew> I'd like something that's more of a time share thing
2017-11-18T19:59:12 < jadew> so if you want to work for a day straight on the CNC, you can do that
2017-11-18T19:59:22 < sync> aandrew: yeah same here, but if you don't show up on the open days or the friday it is basically empty
2017-11-18T20:00:27 < jadew> I wonder if there's anything like that here

2017-11-18T22:00:09 < branjb> everything he cut he was basically sticking it to the ~hackerspace~ selling their machine time to his customers

2017-11-18T23:23:14 < capacitor> i guess its the equiv of a 936
2017-11-18T23:28:33 < jadew> yeah, it's decent
2017-11-18T23:28:54 < jadew> I have the one with the knob tho
2017-11-18T23:29:03 < jadew> not a fan of the digital ones
2017-11-18T23:30:19 < capacitor> digital ones are annoying
2017-11-18T23:30:29 < capacitor> i had one at a place i worked at
2017-11-18T23:30:47 < capacitor> stupid nigger kept setting the 'cal' instead of changing temp
2017-11-18T23:31:13 < capacitor> so every week i'd have to bring a thermocouple and reset it

2017-11-18T23:34:16 < kakimir> why the hell
2017-11-18T23:34:28 < kakimir> what are they thinking with their choise of psu
2017-11-18T23:34:29 < capacitor> cause your mother is a cocksucker from hell
2017-11-18T23:34:40 < kakimir> :D
2017-11-18T23:34:56 < capacitor> the line filter in your smps usually does these things kakimir
2017-11-18T23:35:06 < kakimir> yes
2017-11-18T23:36:46 < kakimir> can I safely ground the fungen to my scope?

2017-11-18T23:37:00 < capacitor> yes
2017-11-18T23:37:17 < capacitor> if you don't believe us, test it with another ground
2017-11-18T23:37:31 < kakimir> I do believe jadew
2017-11-18T23:37:40 < jadew> haha
2017-11-18T23:38:01 < capacitor> it could be crt in disguise, he's a fucking prick
2017-11-18T23:38:04 < kakimir> I wonder how much interference that line noise causes to my circuits being measured
2017-11-18T23:38:10 < jadew> lol
2017-11-18T23:38:38 < kakimir> and if I should fix that grounding issue anyway
2017-11-18T23:38:47 < capacitor> chinese equipment
2017-11-18T23:38:53 < kakimir> yes
2017-11-18T23:39:03 < kakimir> it has done it's job for now
2017-11-18T23:39:10 < jadew> kakimir, if it's floating, you'll always have those kinds of fluctuations
2017-11-18T23:39:11 < kakimir> I just scope with my multimeter
2017-11-18T23:39:20 < kakimir> yes
2017-11-18T23:39:27 < jadew> it shouldn't cause any issue once connected and grounded to your DUT
2017-11-18T23:39:53 < kakimir> currents are really minimal aren't those?
2017-11-18T23:40:22 < capacitor> well

2017-11-18T23:40:30 < jadew> yeah, otherwise you'd see sparks when you'd ground it
2017-11-18T23:40:32 < capacitor> :3
2017-11-18T23:40:34 < jadew> but yeah
2017-11-18T23:40:42 < jadew> what capacitor said
2017-11-18T23:40:44 < kakimir> I don't want to see sparks in my scope
2017-11-18T23:40:51 < capacitor> few hundred microamps is what i see at most
2017-11-18T23:41:07 < kakimir> you have chane gear too?
2017-11-18T23:41:21 < capacitor> as/nzs 3760 is what i have to test appliances to
2017-11-18T23:41:50 < capacitor> http://www.pat-testing-expert.com/support/leakage-tests.php
2017-11-18T23:42:18 < jadew> kakimir, do what capacitor said, ground it to something else if you don't trust its PSU
2017-11-18T23:42:40 < jadew> being a sig gen, it should be possible to safely ground it
2017-11-18T23:42:46 < capacitor> i can feel the leakage current on quite a few regular appliances i test
2017-11-18T23:42:48 < jadew> otherwise it wouldn't be a very useful sig gen
2017-11-18T23:43:03 < capacitor> the djm900nxs is a good one, i've had more than one DJ think its going to electrocute them
2017-11-18T23:43:12 < kakimir> is it leakage or just capacitivelly isolated current?
2017-11-18T23:43:36 < capacitor> the main source is the y-cat across the switching transformer
2017-11-18T23:43:37 < jadew> I don't think it's leakage
2017-11-18T23:43:47 < capacitor> y-cap
2017-11-18T23:44:07 < kakimir> yes
2017-11-18T23:44:28 < capacitor> http://i36.tinypic.com/idvewm.jpg
2017-11-18T23:44:40 < jadew> better function generators have the ground semi-floating
2017-11-18T23:44:44 < capacitor> this is to tame the radiated emissions mate
2017-11-18T23:44:52 < kakimir> semi-floating?
2017-11-18T23:45:04 < jadew> yeah, you can connect their ground to say 30 V
2017-11-18T23:45:19 < kakimir> offset?
2017-11-18T23:45:25 < jadew> but it's still loosely tied to earth
2017-11-18T23:45:33 < jadew> yeah offset from earth
2017-11-18T23:45:52 < kakimir> adjustable?
2017-11-18T23:46:09 < jadew> no, you just connect it to your equipment as long as its GND is within some limits
2017-11-18T23:46:19 < jadew> +- something V from earth
2017-11-18T23:46:39 < kakimir> oh it's clamping
2017-11-18T23:46:52 < kakimir> why you want that?
2017-11-18T23:47:11 < jadew> I don't think it's clamping, more like that's the best they could do, while still having the thing resonably grounded
2017-11-18T23:47:40 < jadew> kakimir, well, ideally, you want it floating, but you also want it grounded when connecting to already floating stuff
2017-11-18T23:48:02 < jadew> I guess that's the compromise

2017-11-19T04:51:14 < jadew> anyone got these?
2017-11-19T04:52:18 < Cracki_> there are such IC clamps
2017-11-19T04:52:27 < Cracki_> there are also individual clamps for the legs
2017-11-19T04:52:56 < jadew> I need something that can be attached on top of a DIP IC, like the 3M stuff, but affordable
2017-11-19T04:52:57 < Cracki_> tend to be complimentary to many logic analyzers
2017-11-19T04:53:06 < Cracki_> what spacing?
2017-11-19T04:53:10 < jadew> 2.54
2017-11-19T04:53:14 < Cracki_> eh trivial
2017-11-19T04:53:21 < Cracki_> individual clamps cost perhaps 1-2 bucks a piece
2017-11-19T04:53:37 < Cracki_> if you want a rigid setup, get pogopins and order a PCB ;)
2017-11-19T04:54:06 < jadew> hmm, I have pogo pins
2017-11-19T04:54:26 < Cracki_> "test hook probes" generally
2017-11-19T04:54:27 < jadew> it wouldn't be easy to fix the board on top of the IC tho
2017-11-19T04:54:39 < Cracki_> paper weight
2017-11-19T04:55:02 < Cracki_> yeah get some test hook probes
2017-11-19T04:55:14 < Cracki_> they can be had in many qualities
2017-11-19T04:55:25 < Cracki_> google images has common sorts
2017-11-19T04:55:45 < jadew> I have those, but I have to probe like 30 signals
2017-11-19T04:55:56 < Cracki_> then it'll look like a hedgehog
2017-11-19T04:56:23 < jadew> yeah, and they unhook often
2017-11-19T04:56:46 < Cracki_> pogo pin PCB with perhaps some widgets that grab the ic from both head ends?
2017-11-19T04:56:47 < jadew> because when you have a couple of them next to eachother they tend to unhook themselves
2017-11-19T04:56:55 < Cracki_> they do?
2017-11-19T04:57:01 < Cracki_> mine don't, they pull quite tightly
2017-11-19T04:57:09 < jadew> you must have better ones
2017-11-19T04:57:15 < Cracki_> or coarser ones
2017-11-19T04:57:23 < jadew> yeah
2017-11-19T04:57:37 < Cracki_> mine don't bend. i've seen ones that bend because the metal is even worse than the cheap stuff I bought
2017-11-19T04:59:10 < jadew> given how expensive this stuff is and that I'll probably have to wait a lot for shipping, I think I'll just start soldering
2017-11-19T04:59:58 < jadew> maybe they're cheapper on farnell
2017-11-19T05:00:07 < jadew> *cheaper
2017-11-19T05:00:41 < jadew> they're not

2017-11-19T05:33:41 < Jak_o_Shadows> ok. Clock maths. I have a 72Mhz clock source. I have a 16bit prescaler. I have a 16 bit counter. I want a period of 0.5s. (it's triggering an interrupt, so duty cycle isn't important). So I do 0.5/2^16 to get the timer per counter increment
2017-11-19T05:34:14 < Jak_o_Shadows> Then I do 72e6 * this number?
2017-11-19T05:35:57 -!- enh [~enhering@2804:1b0:f191:6229:3510:fbdf:6060:bcff] has quit [Remote host closed the connection]
2017-11-19T05:36:52 < jadew> Jak_o_Shadows, you basically want it to trigger twice per second, right?
2017-11-19T05:37:04 < Jak_o_Shadows> 4 times a second
2017-11-19T05:37:09 < Jak_o_Shadows> (i am not clear on this I think)
2017-11-19T05:37:28 < jadew> if the period is 0.5s , then it has to trigger twice per second
2017-11-19T05:37:33 < jadew> 1 / 0.5 = 2
2017-11-19T05:37:54 < Jak_o_Shadows> Hmm. I don't care about the period, I just want an interrupt every 0.25 seconds
2017-11-19T05:38:10 < jadew> you said 0.5 first
2017-11-19T05:39:35 < Cracki_> overflow interrupt, i assume?
2017-11-19T05:40:25 < Cracki_> 72e6 / 2**16 * 0.25
2017-11-19T05:40:42 < jadew> 72e6 / (1 / 0.25)
2017-11-19T05:40:54 < jadew> you'll get the counter value
2017-11-19T05:40:58 < Cracki_> ^
2017-11-19T05:41:20 < Cracki_> ah right, prescalers on stm32 can be any integer
2017-11-19T05:41:26 < jadew> or, if you want to use a prescaler, 72e6 / prescaler / (1 / 0.25)
2017-11-19T05:42:05 < Cracki_> 0.25s = 18000000 clock ticks. distribute over prescaler and counter as needed.
2017-11-19T05:42:39 < jadew> yeah
2017-11-19T05:42:50 < Jak_o_Shadows> So as 18e6 is bigger than the 2^16, I can pick an arbitary timer that will make that fit?
2017-11-19T05:43:12 < Cracki_> counter should be one less than the period, huh? on avrs, it's like that, because the counting goes 0,1,...TOP,0
2017-11-19T05:43:39 < Cracki_> prescaler*(TOP+1) = 18e6
2017-11-19T05:43:44 < Cracki_> not sure of the terminology
2017-11-19T05:44:04 < Jak_o_Shadows> For arguemetns sake, I could pick a prescaler of 512, and comapre at 72e6 / (512)/(1/0.25)
2017-11-19T05:44:09 < Cracki_> true
2017-11-19T05:44:19 < jadew> yes, but 512 won't give you a round number
2017-11-19T05:44:26 < Cracki_> or prescaler 10000, then top = 1800-1
2017-11-19T05:45:02 < Cracki_> or prescaler 7200, top=2500-1
2017-11-19T05:46:01 < jadew> anyone got these? https://www.aliexpress.com/item/Wholesale-Best-Price-10Pcs-Red-Black-P5003-MiNi-grabber-SMD-IC-Test-Hook-Clip-Jumper-Probe/32823359396.html
2017-11-19T05:46:08 < jadew> are they good for DIP?
2017-11-19T05:46:43 < Cracki_> not sure, boss has similar ones in the lab... they definitely look good for dip 2.54mm
2017-11-19T05:47:11 < Cracki_> if the spacing gives you trouble, clip them on zig-zag ;)
2017-11-19T05:47:33 < Cracki_> good that they already have a pin to plug onto
2017-11-19T05:47:39 < jadew> Cracki_, that's what I do with the crappier ones I have
2017-11-19T05:47:46 < jadew> yeah
2017-11-19T05:47:52 < jadew> that's why I'm considering them
2017-11-19T05:48:13 < jadew> I guess I'll take one set and buy more later if they're any good, by the time they arrive I expect to be done with this project anyway
2017-11-19T05:48:55 < Cracki_> solder some pin header onto the dip?
2017-11-19T05:49:07 < Cracki_> like sticking up on both sides?
2017-11-19T05:49:19 < jadew> not a bad idea
2017-11-19T05:49:26 < jadew> better than wires
2017-11-19T05:49:40 < Cracki_> wasn't sure if this is allowed to leave traces or not *g*

2017-11-19T09:07:34 < dongs> 21 days?
2017-11-19T09:07:55 < jpa-> feedback of vreg, control pin of smps chip, input of opamp buffer, depends on how much current you need
2017-11-19T09:08:40 < dongs> yaeh
2017-11-19T09:08:42 < dongs> okay cool
2017-11-19T09:08:48 < englishman> what kind of steps/resolution
2017-11-19T09:09:06 < dongs> doesnt amtter
2017-11-19T09:09:17 < dongs> the constraint is cost
2017-11-19T09:09:19 < englishman> can switch in resistors to feedback
2017-11-19T09:09:27 < dongs> yeah, thats how its done now
2017-11-19T09:10:11 < jpa-> what voltages?
2017-11-19T09:10:32 < dongs> just 1.x to 5V
2017-11-19T09:10:42 < dongs> i think ill just do dac or pwm to RC like that appnote says
2017-11-19T09:11:31 < jpa-> you could get 1.8..5V by putting STM32 DAC output directly to 1.8V fixed voltage regulator GND pin
2017-11-19T09:13:47 < englishman> heh
2017-11-19T09:16:24 < dongs> jpa, lol what
2017-11-19T09:16:42 < dongs> what does that do with its output current
2017-11-19T09:21:13 < jpa-> shouldn't affect much, (modern) regulators only put like 100µA into gnd pin
2017-11-19T09:23:18 < jpa-> stm32 dac output also has the internal buffer, though annoyingly that loses 0.2V at each end
2017-11-19T09:35:15 < dongs> jpa so STM32 and target have common ground
2017-11-19T09:35:21 < dongs> vreg has VIN, VOUT to target
2017-11-19T09:35:26 < dongs> and its GND is sorta floating with DAC output
2017-11-19T09:35:31 < dongs> and that still works?
2017-11-19T09:35:50 < jpa-> yeah
2017-11-19T09:36:13 < dongs> https://image.slidesharecdn.com/ltclt1965-lownoiseldolinearregulatoraudio-110313221159-phpapp01/95/lt1965-low-noise-ldo-linear-regulator-4-728.jpg?cb=1303085136
2017-11-19T09:36:14 < jpa-> it probably won't be the most accurate thing but should get within 50 mV or so easily enough
2017-11-19T09:36:51 < jpa-> (but try to pick a regulator with small quiescent current, not some 1117 crap :)
2017-11-19T09:37:01 < dongs> all the current is on the pmos and none of it goes to ground?
2017-11-19T09:37:18 < jpa-> only the current needed by opamp and vref goes to ground
2017-11-19T09:37:29 < dongs> mhm
2017-11-19T09:37:36 < dongs> thats fucking neat
2017-11-19T09:38:35 < jpa-> and on good regulators it is small enough that stm32 dac can handle it; it can do something like 1mA if the buffer is on.. with the buffer off it has 15kohm internal resistance which will give some offset
2017-11-19T10:24:49 < dongs> qI will increase with LDO output current isnt it?
2017-11-19T10:25:02 < dongs> im loking at lm1117 its specd at 5mA/10mA max
2017-11-19T10:25:12 < dongs> i kinda wanna try this wiht a power supply just to see if it works
2017-11-19T10:25:13 < dongs> eheh

2017-11-19T14:39:13 < noonien> is there any way to emulate a stm32f4? preferably with a few leds?
2017-11-19T14:40:54 < kakimir> you can emulate the core
2017-11-19T14:41:36 < kakimir> but peripherals you need to write yourself
2017-11-19T14:41:51 < noonien> i see

2017-11-19T14:42:40 < kakimir> I don't know if some pro tools have peripheral models in them

2017-11-19T14:48:48 < noonien> i've been trying to get into cortexes using STM32 for ages
2017-11-19T14:49:08 < noonien> i've got multiple dev boards but i'll probably start on a STM32F407VET6 board
2017-11-19T14:49:29 < noonien> my main gripe is with using C, even C++. they're awesome languages, but i hate them
2017-11-19T14:50:01 < noonien> i've finally discovered a decent language that i could use for this, Nim. and would like to give it a try
2017-11-19T14:50:48 < noonien> but i'll probably have to doa lot of testing to get everything to work fine and would rather not have a mess of cables of my desk
2017-11-19T14:51:01 < noonien> is there a bootloader i could use probably?
2017-11-19T14:51:34 < PaulFertser> noonien: just use stlink or some other swd debugger and debug on live target.
2017-11-19T14:51:54 < noonien> I've got a tumpa
2017-11-19T14:51:54 < PaulFertser> noonien: emulators would be waste of time
2017-11-19T14:52:00 < noonien> but I still have to power the board separately
2017-11-19T14:52:17 < PaulFertser> noonien: you can get 5V from tumpa.
2017-11-19T14:52:34 < PaulFertser> And 3.3V too iirc, would need to check to tell for sure.
2017-11-19T14:52:47 < noonien> well, since I'm trying to get Nim to work, and don't really have any experience configuring arm peripherals/clocks, it might take quite a few flashes
2017-11-19T14:52:51 < PaulFertser> noonien: if you have a dev board, probably it already comes with a debugger?
2017-11-19T14:53:24 < PaulFertser> noonien: you can flash all day long, it's not like the erase limit is anywhere near practically dangerous.
2017-11-19T14:53:25 < noonien> it's just a chinese dev board from ebay

2017-11-19T14:54:14 < PaulFertser> noonien: btw, have you also considered rust? It seems to be a sane language, and many stm32 peripherals are supported in nice way it seems.
2017-11-19T14:54:33 < noonien> I have, yes
2017-11-19T14:54:35 < PaulFertser> noonien: you can use swd with tumpa if you add a "resistor hack".
2017-11-19T14:55:02 < noonien> there's a stm32 rust library that hasn't been updated for a while
2017-11-19T14:55:31 < noonien> also, I really tried giving rust a chance, I find it a way overenginered language
2017-11-19T14:55:42 < noonien> they've managed to make it even less unreadable than C++
2017-11-19T14:55:59 < noonien> it might be trying to compete with perl on that front
2017-11-19T14:56:22 < PaulFertser> They bear no legacy contstraints of the language, and they provide compile-time object lifetime tracking, something that C++ really misses.

2017-11-19T14:58:42 < PaulFertser> Anyway, to ensure you're not wasting your time I suggest getting on-chip debug working first.
2017-11-19T15:00:20 < PaulFertser> That would be much better than emulation and bootloaders.
2017-11-19T15:00:26 < noonien> awesome! thanks for the tip
2017-11-19T15:00:42 < noonien> can debugging not be done via jtag?
2017-11-19T15:00:59 < noonien> or is SWD better somewhow?
2017-11-19T15:01:08 < PaulFertser> noonien: swd requires less pins that jtag.
2017-11-19T15:01:42 < noonien> ah, yes, that's not an issue atm since i'm just trying to get blinky running

2017-11-19T16:01:45 < Laurenceb_> nope sorry
2017-11-19T16:14:00 < noonien> I've managed to get gdb working on a TUMPA with stm32f103, but I have to power the board separately, is this normal?
2017-11-19T16:14:03 < BrainDamage> before starting such endevour do a small profitability calculation
2017-11-19T16:14:12 < BrainDamage> check average insolation and wind speed
2017-11-19T16:29:50 < Laurenceb_> muh Rothercaust! Nevar forget the 6 gorrilian hymens torn
2017-11-19T16:30:56 < PaulFertser> noonien: if your question is whether the jtag connector on tumpa has 3.3V power output, then the answer is no, it doesn't.
2017-11-19T16:31:47 < noonien> PaulFertser: awesome, thanks for clearing it up
2017-11-19T16:32:10 < noonien> i'll look for to see if there are any other 3v3 outs on the TUMP and just manually wire it
2017-11-19T16:32:20 < PaulFertser> noonien: there're some other, yes, see http://www.tiaowiki.com/w/TIAO_USB_Multi_Protocol_Adapter_User's_Manual
2017-11-19T16:32:22 < noonien> so I don't have to have multiple usbs
2017-11-19T16:33:53 < PaulFertser> noonien: I suggest you get 5V from tumpa and connect to the target's LDO input.

2017-11-19T16:36:24 < noonien> I've got a cheapo chinese dev board. i think the only way to input to the voltage regulator is through the usb port
2017-11-19T16:38:46 < PaulFertser> noonien: the blue pill one?

2017-11-19T16:41:04 < noonien> here's the schematic: https://gronlier.fr/blog/wp-content/uploads/2015/07/stm32f103c8t6.pdf
2017-11-19T16:42:28 < noonien> i'm pretty much a newb to electronic engineering. but from what I can see the usb ports VCC goes to VCC5
2017-11-19T16:44:50 < PaulFertser> I'm a big fan of the grocery store
2017-11-19T16:45:27 < noonien> there are some +5V pins, but I don't think I should supply power there
2017-11-19T16:45:36 < PaulFertser> noonien: why not?
2017-11-19T16:45:40 < noonien> it's probably safer to just stick wit the usb powering
2017-11-19T16:46:10 < noonien> the schematic is kind of strange
2017-11-19T16:46:25 < noonien> it doesn't show where +5V pins are from
2017-11-19T16:47:02 < PaulFertser> noonien: all +5V nets are connected
2017-11-19T16:47:09 < noonien> actually, it does, yeah
2017-11-19T16:47:41 < noonien> and form what I can see, the voltage regulator is actually using that same net, awesome! :D

2017-11-19T18:07:49 < englishman> yeah the vm backups seemed sketchy
2017-11-19T18:07:58 < kakimir> okay I had wrong comparator
2017-11-19T18:08:07 < englishman> im still only 1/3 capacity on the synodongs
2017-11-19T18:08:11 < englishman> maybe next year il upgrade
2017-11-19T18:08:16 < ReadErr> did u try the syno tool?
2017-11-19T18:08:19 < ReadErr> for backups
2017-11-19T18:08:22 < ReadErr> its pretty good
2017-11-19T18:08:23 < kakimir> wrong pmos pinout in reverse protection
2017-11-19T18:08:25 < englishman> man i cannot stand syno software
2017-11-19T18:08:37 < ReadErr> its clientless
2017-11-19T18:08:42 < kakimir> and probs fried my regulators doing all the stupid stuff
2017-11-19T18:08:55 < englishman> its easy, sure, but when something inevitably fucks up due to lunix it's impossible to fix

2017-11-19T18:14:55 < englishman> interesting
2017-11-19T18:15:05 < englishman> il try it out as a backup for syncthing
2017-11-19T18:15:10 < englishman> that crashes pretty often
2017-11-19T18:15:15 < englishman> backup the backup tool
2017-11-19T18:15:22 < ReadErr> well syncthings isnt a backup tool
2017-11-19T18:15:35 < Steffanx> ^ :D
2017-11-19T18:15:37 < ReadErr> you can run syncthings to replicate teh data you save from that tool
2017-11-19T18:15:41 < englishman> well im def using it like that
2017-11-19T18:15:45 < englishman> for the phone too
2017-11-19T18:15:50 < englishman> pulls the pix off and archives them

2017-11-19T18:16:00 < englishman> ?
2017-11-19T18:16:09 < englishman> syncthing crashes on windows mainly
2017-11-19T18:16:15 < englishman> probably because it is lunix soft
2017-11-19T18:16:39 < fest> I've got a few boards which make contact with an array of pogo pins (basically- pogo pin to copper pad, but the copper pad has some tin on it because it had wires soldered on for debugging). This contact is very unreliable (works for a day after cleaning/rubbing the pads). Any ideas on making it more reliable?
2017-11-19T18:16:43 < Steffanx> or because it hates canucks, probably that,
2017-11-19T18:17:06 < fest> i.e. those silver trace drawing pens, conductive epoxy?
2017-11-19T18:17:14 < englishman> ENIG coating
2017-11-19T18:17:37 < fest> the problem seems to be the tin which is left on those pads after debugging :/
2017-11-19T18:18:00 < englishman> yeah, your pogo pin has to pierce thru the oxidation

2017-11-19T18:18:28 < englishman> use different pads for soldering than pogopins

2017-11-19T18:18:40 < englishman> also you can get different pogo pin tips that might work better
2017-11-19T18:18:46 < englishman> oh yeah that wont work at all
2017-11-19T18:18:53 < englishman> those are meant to seal against a PTH hole
2017-11-19T18:20:40 < fest> what I'm looking for is emergency fix for existing boards- obviously, enig/gold plating pads and not touching them and changing the pins (or even changing it to different type of contact) is best solution

2017-11-19T23:58:02 < Laurenceb_> looks like lunix disables the mic volume control at the os level if the device has no preamp or hardware volume control capability
--- Day changed Mon Nov 20 2017
2017-11-20T00:00:39 < kakimir> jadew: yes
2017-11-20T00:02:12 < kakimir> or maybe not
2017-11-20T00:03:29 < jadew> why not?
2017-11-20T00:03:38 < jadew> not fan of the actor?
2017-11-20T00:05:01 < jadew> I can recommend you one with Robert Pattinson if that's more up your alley
2017-11-20T00:07:17 < jadew> that would be the lost city of Z
2017-11-20T00:07:21 < jadew> similar theme
2017-11-20T00:21:01 < Cracki_> does it contain vampires
2017-11-20T00:21:12 < Cracki_> Z sounds like zombies
2017-11-20T00:25:32 < jadew> no, they're both based on true stories
2017-11-20T00:34:28 < dongs> < Laurenceb_> looks like lunix disables the mic volume control
2017-11-20T00:34:35 < dongs> lunix has working audio support for more than 2 chipsets??
2017-11-20T00:34:40 < dongs> shocking
2017-11-20T00:34:56 < dongs> last i checked lunix still recommended you to get an external PCI sound card
2017-11-20T00:34:56 < Laurenceb_> it has support for stm32 :P
2017-11-20T00:35:11 < dongs> cuz "onboard audio sucks!!11oneone"
2017-11-20T00:35:23 < Laurenceb_> yeah u need xmos
2017-11-20T00:45:29 < zyp> Laurenceb_, so what you're saying is that if the hardware doesn't support mic volume control, you don't get mic volume control?
2017-11-20T00:45:59 < zyp> and if so, is this unexpected?
2017-11-20T00:46:01 < dongs> did you know? lunix still doesnt have a kernel audio mixer either
2017-11-20T00:46:12 < Laurenceb_> zyp: nah thats expected
2017-11-20T00:46:18 < dongs> cuz doing it in C++ in userspace is so much better
2017-11-20T00:46:20 < Laurenceb_> but its not what I get on windows
2017-11-20T00:46:22 < dongs> fucking poettering
2017-11-20T00:46:34 < zyp> haha
2017-11-20T00:46:43 < Laurenceb_> so on windows it looks like i need to add a .inf file
2017-11-20T00:46:51 < dongs> infwhat
2017-11-20T00:46:56 < dongs> bro, what version of windows are you using
2017-11-20T00:47:01 < Laurenceb_> any
2017-11-20T00:47:08 < dongs> you didnt need to give a fuck about inf files since like winxp
2017-11-20T00:47:13 < Laurenceb_> wut
2017-11-20T00:47:24 < Laurenceb_> they are still documented on windozer site
2017-11-20T00:47:37 < dongs> Laurenceb_: any hardware bought in the last decade will just haev drivers autoinstalled from windows update
2017-11-20T00:47:49 < zyp> uh, pretty sure usb audio doesn't require vendor drivers on windows
2017-11-20T00:47:50 < Laurenceb_> hmf
2017-11-20T00:47:56 < Laurenceb_> sure it works atm
2017-11-20T00:48:08 < dongs> oh tis USB audio? lol
2017-11-20T00:48:09 < Laurenceb_> but I meant i could overwrite the volume thing
2017-11-20T00:48:16 < Laurenceb_> using a .inf
2017-11-20T00:48:16 < dongs> yeah usb class definitely does not

2017-11-20T00:59:32 < karlp> BrainDamage: yeah, proper questions from you of course. building test harness host board to plug all the nucleo64 boards into for locm3 testing. Adding a port for plugging a cheap fx2 logic analyser on, so I can do auto testing with sigrok,
2017-11-20T01:00:21 < karlp> I'm estimating like 20-30mm on the side tap to the logic analyser port, plus 30-40mm or so between target/host.
2017-11-20T01:00:29 < karlp> how fast can I go on the signals before I need to do anything I guess?
2017-11-20T01:00:48 < karlp> i2c/uart are probably fine, spi might have an upper limit?
2017-11-20T01:06:48 < BrainDamage> the highest frequency for squarewaves is 2/trise for signal integrity, assuming say, 30MHz spi that gives us 30ns period, trise would be say, 1/5th of a semiperiod so 30/2/5 ~3ns, so that gives us a frequency of approx ~700MHz for signal integrity, in turn that has a wavelength of c/700MHz ~430mm, now a common ballpark is that when your circuit size is comparable to 1/10th of the wavelength, you start seeing
2017-11-20T01:06:50 < BrainDamage> effects, since you said it's overall 60mm it's more than 40, so yes, it'll distort the signal a bit leaving it dangling there
2017-11-20T01:07:31 * karlp loves you
2017-11-20T01:08:13 < karlp> so, is the solution "throw small series resistors right by the stub off to the dangling trace, so that it dissipates any reflections on that line?
2017-11-20T01:08:25 < karlp> I guess this also then changes when the LA is plugged in/not in too.
2017-11-20T01:09:02 < BrainDamage> the LA tends to be a very high impedance, so it doesn't change a lot when it's in compared to the open circuit case
2017-11-20T01:09:25 < BrainDamage> series termination should work
2017-11-20T01:09:28 < karlp> adds capacitance though, I've foudn that out the hardware with insufficient i2c pullups, but that's already taken care of.
2017-11-20T01:09:51 < karlp> and yeah, just like 22ohm right on the beginning of the stub, by the T-junction?
2017-11-20T01:12:15 < BrainDamage> i forgot the exact value for series termination, it was either 2x or 1/2 of the nominal impedance, if 22 is what you've seen before then i guess it was 1/2 and yes, that should fix it
2017-11-20T01:12:56 < ohsix> naomi wu got dale dougherty
2017-11-20T01:14:08 < BrainDamage> if you feel brave there's faster terminations using clamping diodes and caps, buuut, i'd say to keep it simple first
2017-11-20T01:14:34 < ohsix> doesn't spi have bit timing stuff that doesn't imply you need edges faster than 30mhz?
2017-11-20T01:14:44 < ohsix> or 60 i guess
2017-11-20T01:14:58 -!- vampi-the-frog [~vampi@unaffiliated/vampirefrog] has quit [Quit: Get up on outta here!]
2017-11-20T01:15:22 < BrainDamage> if you read i've used 1/5th of a semiperiod for edges
2017-11-20T01:15:43 < ohsix> right
2017-11-20T01:16:01 < ohsix> not a question about what you've said but of spi
2017-11-20T01:19:27 < ohsix> nm forgot there wasn't a specification for spi
2017-11-20T01:20:18 < ohsix> so what's semiperiod in this case, 1/2 is the normal bit time/clock sampling period in most diagrams of spi that i've seen
2017-11-20T01:20:26 < ohsix> just 1/5th of the bit frame or the clock frame?
2017-11-20T01:21:00 < ohsix> or is that nomenclature used in the st docs for the spi controller
2017-11-20T01:22:33 < ohsix> trying too hard to find something to do, guess finding out what you're talking about isn't on the agenda
2017-11-20T01:26:08 < dongs> fuck
2017-11-20T01:26:11 < dongs> im still banned from digikey
2017-11-20T01:27:36 < karlp> ohsix: well, you can run spi as fast as you want.
2017-11-20T01:28:20 < karlp> I'm -probably- going to just wing it. uart and i2c will be fine, spi I can live with <10Mhz anyway really, the cheap LA it's designed to get plugged into only does 24Mhz sampling anyway
2017-11-20T01:28:29 < karlp> s/probably/will/
2017-11-20T01:28:55 < ohsix> yea but ~everything is defined as a ratio of the stuff, i understand what he means by semiperiod; but haven't seen it used like that by anyone, wondering if it means something else that i dont' actually understand
2017-11-20T01:29:37 < BrainDamage> it's of the clock
2017-11-20T01:30:01 < BrainDamage> bit timings are slave of the clock, it's all what a syncronous protocol does
2017-11-20T01:30:13 < BrainDamage> 10MHz should work ok without adjusting the circuit
2017-11-20T01:30:51 < karlp> kicad might use text files, but ffs, gratuitous reordering of identical elemnts within the files? byebye useful diffs.
2017-11-20T01:31:44 < karlp> thi sis _super_ dumb
2017-11-20T01:31:49 < karlp> eagle does a better job of this
2017-11-20T01:31:56 < ohsix> hm shit, moovee and teevee just died
2017-11-20T01:32:16 < ohsix> BrainDamage: k
2017-11-20T01:32:20 < karlp> man, added a net, it wenbt and renumbered _all_ nets, massive useless diff
2017-11-20T01:32:51 < karlp> .sch diff is sane, are you not meant to version the .net file?
2017-11-20T01:35:24 < ohsix> nice
2017-11-20T01:35:35 < ohsix> in eagle it'll ask you which net you want to keep in the whole net
2017-11-20T01:35:42 < ohsix> does it clobber named nets too?
2017-11-20T01:35:56 < ohsix> or does it just assumed unnamed nets dont' need a name and renumbers without asking
2017-11-20T01:36:00 < ohsix> -d
2017-11-20T01:40:35 < Cracki_> so 30 MBaud SPI rounded up to 700 MHz bw is quite a safety factor
2017-11-20T01:42:24 < ohsix> it's not exactly rounded up, he's talking about the integrity of the fast edge of a square wave
2017-11-20T01:42:30 < Cracki_> yes
2017-11-20T01:42:55 < Cracki_> by nyquist, 15 MHz is the hard limit for signal recovery
2017-11-20T01:43:12 < Cracki_> I'd guess you'd get a nice signal with 150 MHz
2017-11-20T01:43:28 < ohsix> square waves have that infinite frequency content we all know and love
2017-11-20T01:43:33 < Cracki_> yes
2017-11-20T01:43:51 < Cracki_> so the spectral content depends on the drive strength of the IO pins
2017-11-20T01:44:26 < Cracki_> was the question how much degradation a tap for test pads would cause?

2017-11-20T02:18:10 < jsoft> Hmm.
2017-11-20T02:19:21 < jsoft> I need to do dsp stuff @ a certain freq/sample rate. I also want to do DSP stuff at a maximum rate. I was pondering thusly -> some sort of timer + interrupt handler sets sample_now to 1, in the dsp loop it goes.. if ( sample_now ) { // do the things }. Seem legit?
2017-11-20T02:20:07 < dongs> or use rtos wait handles in your dsp thread
2017-11-20T02:20:23 < jsoft> im not using an rtos
2017-11-20T02:20:27 < dongs> then whatever works yeah
2017-11-20T02:20:51 < jsoft> I wonder if the HAL stuff has an easy way to set up timers at the nearest desired resolution
2017-11-20T02:20:52 < dongs> is 'dsp loop' the only thing you have going on?
2017-11-20T02:21:01 < dongs> not any simpler than noraml
2017-11-20T02:21:10 < jsoft> well yeah pretty much. It does display stuff, but only after the dsp loop has to change.
2017-11-20T02:21:23 < jsoft> ie, exit
2017-11-20T02:22:55 < Cracki_> would you have concrete numbers for these rates
2017-11-20T02:23:09 < Cracki_> sounds like you want to sample and then process in batches of samples
2017-11-20T02:23:19 < jsoft> nah, I want the rates fixed.
2017-11-20T02:23:28 < jsoft> So I am making a dsp demo board thingy for a school
2017-11-20T02:23:29 < Cracki_> that's no contradiction
2017-11-20T02:23:43 < jsoft> Cracki_, I suppose not :D
2017-11-20T02:24:23 < jsoft> Cracki_, but the guts is, I have some FIR/IIR filters currently which run as fast as possible.. and so there is no timer or anything going on, so the sample rate is currently based on how fast it can process each loop.
2017-11-20T02:24:35 < Cracki_> ic
2017-11-20T02:24:45 < Cracki_> ah so you want timer-triggered ADC
2017-11-20T02:24:55 < Cracki_> and an interrupt routine on that
2017-11-20T02:24:57 < jsoft> After talking to the bloke at school, he would like to have fixed rates ( particuarly for lower order filters where the sample rate ends up being 100's of kHz for ~ 2kHz filters )
2017-11-20T02:25:07 < Cracki_> yes yes
2017-11-20T02:25:07 < jsoft> yeah I was thinking I can do both
2017-11-20T02:25:14 < Cracki_> set up timer-triggered ADC
2017-11-20T02:25:22 < jsoft> just a simple volatile flag
2017-11-20T02:25:28 < Cracki_> but why
2017-11-20T02:25:33 < jsoft> why what?
2017-11-20T02:25:35 < Cracki_> why free running sampling
2017-11-20T02:25:40 < Cracki_> just trigger it with a timer
2017-11-20T02:25:46 < Cracki_> it'll be nice and all
2017-11-20T02:25:50 < jsoft> The faster it runs the smoother the output
2017-11-20T02:25:54 < Cracki_> sure
2017-11-20T02:26:06 < Cracki_> but how does that hook up?
2017-11-20T02:26:15 < jsoft> What do you mean
2017-11-20T02:26:16 < Cracki_> do you process each adc sample?
2017-11-20T02:26:21 < Cracki_> or do you throw some away?
2017-11-20T02:26:27 < jsoft> I read adc -> process -> set dac
2017-11-20T02:26:29 < Cracki_> or do you throw some _processed_ samples away?
2017-11-20T02:26:36 < Cracki_> ah, you have a DAC too
2017-11-20T02:26:43 < Cracki_> dac rate = adc rate?
2017-11-20T02:26:48 < jsoft> yes
2017-11-20T02:27:00 < Cracki_> ok, then you _don't_ have to think about rate conversion (resampling)
2017-11-20T02:27:24 < jsoft> no but I have to slow down the rate it get's processed for some filters.
2017-11-20T02:27:30 < jsoft> Which essentially means a delay.
2017-11-20T02:27:31 < Cracki_> why?
2017-11-20T02:27:36 < Cracki_> delay or slow down?
2017-11-20T02:27:56 < jsoft> Well effectively 'sample' slower.
2017-11-20T02:28:05 < Cracki_> delay just means you feed some dummy values into the DAC before actual adc values come in
2017-11-20T02:28:09 < Cracki_> huh
2017-11-20T02:28:14 < jsoft> no.
2017-11-20T02:28:17 < Cracki_> so you DO have adc rate != dac rate?
2017-11-20T02:28:22 < jsoft> no.
2017-11-20T02:28:33 < jsoft> I mean delay -> read -> process -> set
2017-11-20T02:28:34 < Cracki_> then how is something going to be slower?
2017-11-20T02:28:53 < Cracki_> what's the purpose of the delay? just lowering the samplgin rate?
2017-11-20T02:28:57 < jsoft> yes
2017-11-20T02:29:05 < Cracki_> ok, so you're not thinking in terms of a timer
2017-11-20T02:29:13 < jsoft> Well I could use a timer.
2017-11-20T02:29:20 < Cracki_> it'd be best I think
2017-11-20T02:29:33 < Cracki_> you'd know the data rate
2017-11-20T02:29:48 < jsoft> And the easiest way I was thinking, was to just loop over a flag ( which changes via the timer ) and then it continues.
2017-11-20T02:29:52 < Cracki_> no need to compute the delay per sample, which would depend on the time the code takes anyway
2017-11-20T02:29:59 < Cracki_> nah, that's not easier
2017-11-20T02:30:00 < jsoft> And that way I can have a fixed sample rate, or maximal
2017-11-20T02:30:15 < jsoft> why is that not easy ?
2017-11-20T02:30:25 < Cracki_> ISRs are easy
2017-11-20T02:30:25 < jsoft> what am I missing here
2017-11-20T02:30:31 < jsoft> yeah?
2017-11-20T02:30:34 < Cracki_> set up the timer to poke ADC regularly
2017-11-20T02:30:45 < Cracki_> adc finished interrupt -> isr for the DSP stuff
2017-11-20T02:30:55 < Cracki_> dsp stuff feeds the dac
2017-11-20T02:31:10 < Cracki_> and then I'm out because I have no idea how your dac wants to be driven
2017-11-20T02:31:22 < jsoft> thats really not that much different from ISR -> set flag; dsp loop checks flag, -> read -> process -> set
2017-11-20T02:31:23 < jsoft> ?
2017-11-20T02:31:49 < Cracki_> the difference being you just made your own interrupt flag
2017-11-20T02:32:09 < jsoft> Oh ok I see what you mean
2017-11-20T02:32:33 < Cracki_> there's also no point in sampling faster than your DSP code can process
2017-11-20T02:32:44 < jsoft> :|
2017-11-20T02:32:50 < jsoft> I do not intend to
2017-11-20T02:33:08 < Cracki_> ah ok so that flag of yours, do you want it to come from a timer, or the ADC conversion?
2017-11-20T02:33:14 < jsoft> timer

2017-11-20T02:33:24 < dongs> they sent me spam and actualyl keep trying to reply to it
2017-11-20T02:34:08 < Cracki_> you can busy-wait for the timer interrupt flag directly, no need for a timer ISR to set a custom byte somewhere
2017-11-20T02:34:28 < jsoft> Cracki_, yeah I just realized that after you mentioned the 'own interrupt flag' :)
2017-11-20T02:34:31 < Cracki_> the timer would be set up to generate the interrupt, but wouldn't have an ISR
2017-11-20T02:34:49 < dongs> hey waht
2017-11-20T02:34:51 < Cracki_> _if_ you want your dsp code to be an explicit loop rather than an ISR
2017-11-20T02:34:52 < dongs> there's spartan 7 series
2017-11-20T02:34:54 < dongs> from xilinx
2017-11-20T02:35:11 < jsoft> Cracki_, yeah because in some cases I want to run the loop full tit, no timer
2017-11-20T02:35:17 < jsoft> so that would work out well.
2017-11-20T02:35:28 < Cracki_> ic
2017-11-20T02:35:32 < jsoft> save an instruction checking the flag I guses.
2017-11-20T02:35:34 < jsoft> guess
2017-11-20T02:35:44 < jsoft> Hmm
2017-11-20T02:35:46 < Cracki_> saves the ISR setting the bool
2017-11-20T02:35:49 < jsoft> Yeah
2017-11-20T02:36:13 < dongs> sounds like your shit will fail
2017-11-20T02:36:15 < Cracki_> and since you look at some interrupt flag, it might be faster to read than real SRAM
2017-11-20T02:36:51 < Cracki_> (or however this port-mapped stuff works I'm used to from AVRs)
2017-11-20T02:37:15 < jsoft> Sounds like a plan anyway, Cheers Cracki_ :)
2017-11-20T02:38:08 < Cracki_> ok, dsp question of my own: lowpass using gaussian kernel, how is the sigma for some specific cutoff freq figured?
2017-11-20T02:38:27 < Laurenceb_> with matklab
2017-11-20T02:38:38 < dongs> <laurenceb> install lunix, run octave
2017-11-20T02:38:43 < jsoft> yeah I use octave
2017-11-20T02:38:50 < dongs> no wonder your shit doesnt work
2017-11-20T02:39:02 < jsoft> dongs, whom ever said it did not work?

2017-11-20T02:39:40 < Cracki_> from playing with values here, it seems the -3dB criterion applies if I take sigma = lambda
2017-11-20T02:39:45 < dongs> what teh hell
2017-11-20T02:39:48 < dongs> i got sent datasheet from 'meticom'

2017-11-20T02:40:34 < Cracki_> ah, wikipedia seems to agree
2017-11-20T02:46:42 < Cracki_> ah no sigma = 1 / (2 pi f_c)

2017-11-20T03:05:56 < dongs> and 200liter/minute $100 trash
2017-11-20T03:06:01 < dongs> but i cant find anything normal
2017-11-20T03:06:23 < Cracki_> so any old pump, just no plastic parts eh?
2017-11-20T03:06:30 < dongs> electric
2017-11-20T03:06:38 < dongs> but yeah wahtever
2017-11-20T03:06:47 < dongs> looking on ebay for fuel pumps only finding aids
2017-11-20T03:07:08 < dongs> https://www.ebay.com/itm/cocks/282386948116 this is too slow, that flow rate seems almost like what you'd get fro mfree flow

2017-11-20T03:07:48 < dongs> no thats too fucking big
2017-11-20T03:09:03 < Cracki_> 200l/min is ~7l/sec, that's some flow rate
2017-11-20T03:09:10 < Cracki_> wait ~3l
2017-11-20T03:09:35 < dongs> https://www.ebay.com/itm/dongs/252711967336 this is ok but kinda expensive
2017-11-20T03:09:42 < Cracki_> I'd figure at least a half inch pipe or you're in trouble.
2017-11-20T03:09:58 < Cracki_> they all look tiny
2017-11-20T03:10:01 < dongs> thats 6l/minute, about what i need
2017-11-20T03:10:26 < Cracki_> ah, 200l/min was a bit generous
2017-11-20T03:11:34 < dongs> Not compatible with alcohol fuels.

2017-11-20T06:20:16 < upgrdman> When it comes to the New York City subways, there’s no such thing as ladies and gentlemen.
2017-11-20T06:20:16 < upgrdman> Conductors on subway trains have been told to stop addressing passengers as “ladies and gentlemen†when making announcements about delays, detours or other things, and instead use the gender-neutral terms “passengers,†″riders,†and “everyone.â€
2017-11-20T06:22:11 < aandrew> well to be fair, it *is* New York... I bet 40% of their population is gender fluid
2017-11-20T06:23:14 < upgrdman> englishman, yes im in so cal, and ever we arent THAT dumb. insulation in walls is very common. not as much as some frozen wasteland, but some pink fiberglass in the walls in common.

2017-11-20T13:40:49 < kakimir> it's a hack
2017-11-20T13:52:25 < zyp> haha
2017-11-20T13:52:35 < zyp> port pattern doesn't seem to match rpi though
2017-11-20T13:52:52 < zyp> but there's plenty of other shit
2017-11-20T13:53:11 < zyp> I wonder why there's so few SBCs with usb on header pins
2017-11-20T13:54:01 < tomeaton17> I am having trouble flashing my stm32 on a pcb I designed. What are good things to check on the board to try and track down the issue?
2017-11-20T13:54:19 < zyp> what sort of trouble?
2017-11-20T13:55:21 < tomeaton17> When trying to flash with openocd it says its unable to connect to target. When using st-util it says there is a usb error when I try to connect to the chip
2017-11-20T13:55:49 < kakimir> what is your debugger?
2017-11-20T13:56:04 < zyp> check the voltage rail on the board that the chip is getting power and that it's not shorted out
2017-11-20T13:56:16 < tomeaton17> Ok will do
2017-11-20T13:56:41 < kakimir> also reset pin condition per datasheet instructions
2017-11-20T13:56:43 < tomeaton17> I use openocd + gdb
2017-11-20T13:56:45 < zyp> all you need to connect over swd is powering the chip and having the swd lines hooked up correctly
2017-11-20T13:57:26 < kakimir> whay device you use for flashing?
2017-11-20T13:57:41 < zyp> so assuming your tools are sane, chances are big that either the chip is not powered correctly or you messed up the swd signals
2017-11-20T13:59:02 < kakimir> or reset
2017-11-20T13:59:12 < zyp> kakimir, reset shouldn't matter
2017-11-20T13:59:33 < kakimir> okay
2017-11-20T13:59:39 < kakimir> also driver issues
2017-11-20T14:00:13 < kakimir> assumption is that there has not been any setup for the current debugger
2017-11-20T14:00:16 < zyp> I'm assuming the tools are tested on known working hardware prior to this to rule out problems there
2017-11-20T14:00:33 < tomeaton17> I use the st link v2, but yes the tools have been tested on other stm32 chips and they flash fine so its the board
2017-11-20T14:00:51 < zyp> tomeaton17, got a schematic for the board?
2017-11-20T14:01:28 < kakimir> is your chip well supported by your installed version of openocd?
2017-11-20T14:01:46 < zyp> kakimir, why are you bringing up shit that doesn't matter?
2017-11-20T14:02:25 < zyp> it's irrelevant how well the chip is supported, the swd interface is the same, the differences doesn't matter until after the target is connected
2017-11-20T14:02:31 < tomeaton17> yes I have used this chip extensively with my current setup
2017-11-20T14:02:41 < kakimir> okay
2017-11-20T14:05:25 < tomeaton17> zyp: https://i.imgur.com/AhSc3hM.png yeah its not getting power. Weird because when I first got the board it was. I know this is a bad schematic and a lot of stuff is left out but dont hate me
2017-11-20T14:06:05 < zyp> oh, one of those small f0s, cute
2017-11-20T14:06:45 < kakimir> battery monitor?
2017-11-20T14:06:48 < kakimir> sweet
2017-11-20T14:07:12 < tomeaton17> yeah. So the f0 is meant to be powerered by the other chip, which outputs 3.3v when its powered on.
2017-11-20T14:07:14 < kakimir> 4cell rite
2017-11-20T14:07:17 < tomeaton17> Yeah
2017-11-20T14:07:30 < kakimir> can I ask what it's to be?
2017-11-20T14:07:58 < tomeaton17> So for the BQ to poweron it needs a rising edge on pin 6 so I am assuming it doesnt get that
2017-11-20T14:08:32 < tomeaton17> its for a quadcopter
2017-11-20T14:09:10 < kakimir> you plan to do more than battery monitoring with that F04?
2017-11-20T14:09:49 < tomeaton17> the f0 is to communicate with the computer on the drone
2017-11-20T14:12:12 < kakimir> yes
2017-11-20T14:17:10 < qyx> the ntc connection is a bit weird, isn't it?
2017-11-20T14:17:42 < kakimir> looks like a hack
2017-11-20T14:18:27 < kakimir> 1uF cap as a "boot button"
2017-11-20T14:18:46 < qyx> I don't get it entirely
2017-11-20T14:19:03 < qyx> also the gnd connection between the first and second cell
2017-11-20T14:19:31 < kakimir> yeah
2017-11-20T14:19:42 < kakimir> weird
2017-11-20T14:20:21 < kakimir> tomeaton17: did you reference to datasheet when placing 1uF cap instead of push button?
2017-11-20T14:20:34 < qyx> what push button
2017-11-20T14:20:58 < tomeaton17> The ground connection was recommended by the ti datasheet
2017-11-20T14:20:59 < kakimir> in simplified example
2017-11-20T14:21:32 < kakimir> tomeaton17: it's problematic if you connect that to your control board that is referenced to cell 0
2017-11-20T14:21:42 < kakimir> at 0volt of pack
2017-11-20T14:21:53 < kakimir> or is it?
2017-11-20T14:22:41 < tomeaton17> No I didnt reference datasheet, but I breadboarded this and it worked as planned. I believe the problem is that pin 6 on u2 is not getting the required voltage spike which should come from the cap
2017-11-20T14:22:43 < tomeaton17> I am not really sure

2017-11-20T14:28:16 < qyx> tomeaton17: I think you forgot to connect the actuall battery pack negative terminal to your ground
2017-11-20T14:28:21 < qyx> -l
2017-11-20T14:28:29 < kakimir> tomeaton17: did you simulate your boot up circuit?
2017-11-20T14:29:03 < qyx> tomeaton17: pin 5 of the P2 connector
2017-11-20T14:29:39 < kakimir> and doesn't your boot up circuit cause massive noise for your temperature measurements when quad takes off?
2017-11-20T14:30:10 < kakimir> you need some sort of latching to it
2017-11-20T14:30:29 < tomeaton17> No I havent simulated it. Yeah that seems like a problem I will add a bodge wire. and finally I am not sure about noise. Just to make it clear I am a pre uni intern so I am kinda out of my depth a bit
2017-11-20T14:30:58 < kakimir> maybe replace cap with pmos
2017-11-20T14:31:04 < kakimir> gate connected to 3v3
2017-11-20T14:31:32 < kakimir> when 3v3 is alive pmos will open circuit
2017-11-20T14:31:57 < englishman> nah stm32 is a good beginner platform. gets you in the deep end of the pool
2017-11-20T14:32:07 < kakimir> llol
2017-11-20T14:32:09 < kakimir> no
2017-11-20T14:32:22 < kakimir> it's learning to swim
2017-11-20T14:32:45 < qyx> tomeaton17: also you should connect your ld1117 before the 100R resistor otherwise it may influence your measurement
2017-11-20T14:33:17 < qyx> and caps, we need more caps
2017-11-20T14:33:33 < kakimir> is there bypassing?
2017-11-20T14:33:50 < kakimir> no
2017-11-20T14:33:59 < kakimir> LD1117 requires some
2017-11-20T14:34:10 < kakimir> was it at least in output
2017-11-20T14:34:23 < kakimir> if input is low impendance
2017-11-20T14:34:35 < kakimir> let's say directly to lipo
2017-11-20T14:34:58 < kakimir> but still it needs... 100n at least in input
2017-11-20T14:38:42 -!- enh [~enhering@2804:1b0:f191:6229:c4f2:6e59:bcc0:f3f] has quit [Ping timeout: 258 seconds]
2017-11-20T14:40:55 < kakimir> hmm that pmos thing... it needs 3v3 source for boot up voltage so that logic level gate would work
2017-11-20T14:41:09 < kakimir> I mean cell side of it
2017-11-20T14:42:26 < kakimir> These are measured by applying a factory-trimmed internal 10-k pull-up resistance to an
2017-11-20T14:42:29 < kakimir> internal regulator value of nominally 3.3 V
2017-11-20T14:42:35 < kakimir> TS1
2017-11-20T14:42:58 < aandrew> word
2017-11-20T14:43:08 < tomeaton17> yeah the ld1117 part is bad I know that
2017-11-20T14:43:22 < tomeaton17> So replace the cap with a pmos gate
2017-11-20T14:43:28 < kakimir> if there was to say 4.2 in source pin of pmos there would be -0.9V gate voltage
2017-11-20T14:43:55 < kakimir> that would leave boot up circuit closed
2017-11-20T14:44:30 < kakimir> in quad copter ld1117 is fine.. you are not saving power there
2017-11-20T14:45:25 < kakimir> you could use some pmos that has higher gate threshold than -0.9 but lower than -2,7V
2017-11-20T14:46:19 < kakimir> something like -1,8V or so
2017-11-20T14:46:43 < tomeaton17> the ld1117 is for the acs770
2017-11-20T14:46:52 < kakimir> but you don't need to boot it up when cell voltage is -2,7V
2017-11-20T14:47:43 < kakimir> so even gate threshold -2,7V would probably do
2017-11-20T14:49:20 < kakimir> maybe add RC circuit for gate for some delay if you feel like it
2017-11-20T14:50:10 < kakimir> tomeaton17: yeah it's 5volt device
2017-11-20T14:50:17 < karlp> why does tomeaton have such big decoupling caps?
2017-11-20T14:51:09 < qyx> wtf DFN8 to DIP adapter 11€
2017-11-20T14:51:15 < kakimir> tomeaton17: is there missing ground connection in stm32 VSS?
2017-11-20T14:51:22 < kakimir> it lacks joint
2017-11-20T14:51:40 < kakimir> did your schematic pass the tests?
2017-11-20T14:51:58 < kakimir> I don't remember how eagle works in terms of those joint things
2017-11-20T14:52:15 < qyx> is it eagle?
2017-11-20T14:52:26 < tomeaton17> no its kicad
2017-11-20T14:52:42 < kakimir> oh.. it is
2017-11-20T14:53:05 < tomeaton17> Ah I managed to get it to flash, yeah the problem is that the bq is not getting turned on
2017-11-20T14:54:01 < kakimir> it says it can take 2ms to boot and then regulator may have it's own delay
2017-11-20T14:54:25 < kakimir> max threshold is 1V

2017-11-20T14:55:50 < aandrew> problem solved. next?
2017-11-20T14:56:06 < rajkosto> and chea
2017-11-20T14:56:12 < rajkosto> no optics
2017-11-20T14:56:13 < dongs> SFP is fucking cheap
2017-11-20T14:56:17 < aandrew> lol 10gbps for cheap
2017-11-20T14:56:24 < dongs> i buy 3meter sfp+ copper cables for like $10
2017-11-20T14:56:28 < dongs> how much cheaper do you want it
2017-11-20T14:56:34 < rajkosto> dongs, but those need transcievers
2017-11-20T14:56:34 < dongs> thats including both SFP ends

2017-11-20T14:57:49 < dongs> no idea, its german shit
2017-11-20T14:57:50 < rajkosto> i will use normal cat7 cable
2017-11-20T14:57:52 < aandrew> dongs: yeah
2017-11-20T14:57:55 < dongs> they have public datasheets on site
2017-11-20T14:58:01 < aandrew> yeah I noticed
2017-11-20T14:58:03 < aandrew> surprising
2017-11-20T14:58:05 < dongs> im not quite sure what problem tis solving
2017-11-20T14:58:21 < dongs> just level shifting for dphy?
2017-11-20T14:58:36 < aandrew> most times when you talk anything high data rate it's locked down super sekrit bullshit where they want a semen sample before they'll give you an email address
2017-11-20T14:58:46 < aandrew> no
2017-11-20T14:58:50 < aandrew> MIPI-parallel
2017-11-20T14:59:05 < dongs> i dont think thats waht it does
2017-11-20T14:59:16 < aandrew> The MC20001 is a high performance FPGA bridge IC, which converts a single MIPI D-PHY compliant

2017-11-20T14:59:23 < dongs> right
2017-11-20T14:59:28 < dongs> cmos low speed = paralell?
2017-11-20T14:59:38 < aandrew> yep
2017-11-20T14:59:55 < dongs> but block diagram doesnt show parallel
2017-11-20T15:00:00 < dongs> just shows lvds P/N shit
2017-11-20T15:00:00 < aandrew> er no
2017-11-20T15:00:03 < dongs> for both high and slow speed
2017-11-20T15:00:03 < aandrew> sorry
2017-11-20T15:00:05 < aandrew> you're right
2017-11-20T15:00:08 < aandrew> it's a level translator
2017-11-20T15:00:08 < aandrew> oh
2017-11-20T15:00:09 < aandrew> I sere
2017-11-20T15:00:11 < aandrew> see
2017-11-20T15:00:30 < dongs> i think you still need ~gbps stuff on the output ends
2017-11-20T15:00:30 < aandrew> you know how MIPI has that bullshit LVDS layered with the goofy low speed shit?
2017-11-20T15:00:32 < aandrew> this breaks it out
2017-11-20T15:00:34 < aandrew> yes
2017-11-20T15:00:35 < dongs> yeah
2017-11-20T15:00:36 < aandrew> your'er right
2017-11-20T15:00:45 < aandrew> it's essentially a level shifter

2017-11-20T15:02:47 < tomeaton17> what would you recommend for simulation
2017-11-20T15:03:00 < dongs> so you enter shit like rez/porch/etc and it spits out register write config

2017-11-20T15:03:44 < dongs> ..
2017-11-20T15:03:57 < dongs> waht are you connecting it to

2017-11-20T15:04:43 < rajkosto> which is what i want
2017-11-20T15:04:44 < dongs> so just use any random socket
2017-11-20T15:04:45 < dongs> and dont care
2017-11-20T15:04:50 < aandrew> rajkosto: careful design, using high speed connectors designed for this shit (PCIe, USB3, SATA) and a baord house who isn't lying about impedance control
2017-11-20T15:05:23 < qyx> I would try hdmi/dp cables then
2017-11-20T15:05:29 < rajkosto> 3 lanes
2017-11-20T15:05:29 < dongs> yeah, ^ this
2017-11-20T15:05:31 < rajkosto> not enough
2017-11-20T15:05:34 < dongs> DP is 4 lanes
2017-11-20T15:05:35 < dongs> done
2017-11-20T15:05:52 < dongs> and you got more pins for other random shit
2017-11-20T15:05:58 < aandrew> the FIB/SEM system I was part of design put everything over PCIe connectors and used a quality board house. the entire 11x17" motherboard was nothing but length-matched diffpairs
2017-11-20T15:06:05 < dongs> and even cheapass DP cables will do 20gbps
2017-11-20T15:06:18 < dongs> (not per lane but wahtever)
2017-11-20T15:06:22 < aandrew> aren't DP cables active?
2017-11-20T15:06:24 < dongs> no
2017-11-20T15:06:29 < aandrew> even better
2017-11-20T15:06:30 < dongs> wtf why would tehy be
2017-11-20T15:06:51 < dongs> https://bitguru.files.wordpress.com/2008/11/displayport_pinout11a.gif
2017-11-20T15:06:52 < aandrew> dp3 talks about active cables
2017-11-20T15:07:09 < aandrew> er not dp3, tb3
2017-11-20T15:07:26 < dongs> are TB3 specs/datasheets actually downloadable these days
2017-11-20T15:07:30 < dongs> intel claimed they went "open"
2017-11-20T15:07:35 < dongs> i checked shitboltdeveloper.org
2017-11-20T15:07:38 < dongs> everything is behind paywall
2017-11-20T15:07:41 < rajkosto> dongs, why does the cable internally reverse shit
2017-11-20T15:07:47 < aandrew> I don't know but I pissed off the thunderbolt SIG secretary
2017-11-20T15:07:48 < dongs> rajkosto: just the way dp works
2017-11-20T15:07:56 < aandrew> for three years I wrote them asking for membership but they always turned me down
2017-11-20T15:08:00 < rajkosto> whats wrong with rj45 and short cables
2017-11-20T15:08:00 < dongs> haha
2017-11-20T15:08:07 < aandrew> finally whoever was runnign the email just said "stahp"
2017-11-20T15:08:11 < rajkosto> all pci-e will do if it cant do 3.0 speeds is do 2.0 speeds, its fine
2017-11-20T15:08:46 < dongs> anyway, qyx fucking rules.
2017-11-20T15:08:51 < dongs> shut the hell up and use DP
2017-11-20T15:08:55 < aandrew> qyx?
2017-11-20T15:09:02 < aandrew> oh with the DP idea
2017-11-20T15:09:02 < dongs> < qyx> I would try hdmi/dp cables then
2017-11-20T15:09:03 < aandrew> yeah
2017-11-20T15:09:04 < dongs> yes
2017-11-20T15:09:17 < aandrew> HDMI2.0 cables are cheap too and supposed to be good for 4k
2017-11-20T15:09:21 < aandrew> speaking of which
2017-11-20T15:09:22 < dongs> i mean, shitbolt2 was literally running over minidisplayport connector
2017-11-20T15:09:27 < aandrew> dongs: dcc me a nice 4k monitor
2017-11-20T15:09:29 < aandrew> help a brother out
2017-11-20T15:09:29 < dongs> so you already know it wokrs
2017-11-20T15:10:06 < dongs> and you even get a lowspeed channel for stuff(tm) and a couple GPIO pins (config1/2
2017-11-20T15:10:18 < dongs> all over same cable
2017-11-20T15:10:26 < kakimir> tomeaton17: https://drive.google.com/file/d/13BGZP3MB4IjW6eocj-RtQTvFd7ylkDtJ/view?usp=sharing
2017-11-20T15:10:29 < dongs> btw don't expect DP_PWR to be connected in the cable
2017-11-20T15:10:42 < dongs> its its only for captive cables
2017-11-20T15:10:45 < dongs> (as the diagram shows)
2017-11-20T15:10:56 < kakimir> in this case it was 3cells = 9v in worst case
2017-11-20T15:11:31 < kakimir> 5k = 10k NTC + 10k internal pulldown
2017-11-20T15:12:52 -!- enh [~enhering@2804:1b0:f191:6229:8479:3565:6b04:f7da] has joined ##stm32
2017-11-20T15:13:23 < kakimir> wait.. internal pull up it has.. let's concider it's pull down in this case
2017-11-20T15:13:41 < kakimir> +3v3 rail is zero anyway
2017-11-20T15:14:58 < dongs> kikemir who teh fuck are you taklin to
2017-11-20T15:15:09 < kakimir> myself
2017-11-20T15:15:13 < dongs> k
2017-11-20T15:20:05 < rajkosto> dongs, i dont like the DP twist of the pins
2017-11-20T15:20:17 < aandrew> hahaha
2017-11-20T15:20:24 < aandrew> (talking about the mars skycrane system)
2017-11-20T15:20:25 < aandrew> "A friend and I tried building a model skycrane using estes rocket motors and a drone stabilizationcontrol board. The result was two old dudes sprinting for cover as it pinwheeled after us."
2017-11-20T15:20:34 < tomeaton17> Cool ok, apart from the bootup the board works fine
2017-11-20T15:20:52 < aandrew> rajkosto: what don't you like about the twist of the pins?
2017-11-20T15:21:40 < rajkosto> it means i have to put one of the connectors upside down i think
2017-11-20T15:21:40 < dongs> rajkosto: ....
2017-11-20T15:21:46 < dongs> why does it even matters?
2017-11-20T15:21:50 < rajkosto> in order to achieve straight through
2017-11-20T15:21:51 < dongs> -s
2017-11-20T15:21:56 < dongs> rajkosto: no
2017-11-20T15:22:11 < dongs> SINK and SOURCE pinout is reversed
2017-11-20T15:22:13 < aandrew> he's just autisming now. I get the same way when I get it in my head that something MUST be a way for no other reason than my pigheadedness
2017-11-20T15:22:31 < dongs> i have footprints for both, beacuse thats how it works
2017-11-20T15:22:33 < rajkosto> dongs, in the cable the wires are twisted
2017-11-20T15:22:45 < dongs> wehn you're making a display, pinout is A, and when you're making a dp source, pinout is B
2017-11-20T15:22:53 < dongs> that considers the twist of the cable
2017-11-20T15:22:53 < dongs> the end
2017-11-20T15:22:57 < rajkosto> i am not though
2017-11-20T15:23:09 < dongs> then get fucked and use USB-C
2017-11-20T15:23:14 < dongs> so you can twist it even more.
2017-11-20T15:23:18 < rajkosto> i just want the lanes straight through, so the sink connector will have to be like upside dow
2017-11-20T15:23:24 < dongs> ...
2017-11-20T15:23:29 < dongs> mfkr
2017-11-20T15:23:38 < dongs> (also, they DO make reverse mount DP sockets
2017-11-20T15:23:40 < dongs> for autists like you
2017-11-20T15:23:44 < dongs> wehre plug goes in abckwards
2017-11-20T15:23:53 < rajkosto> ok give me part numbers for 2 with footprints

2017-11-20T15:24:19 < aandrew> lol
2017-11-20T15:24:23 < aandrew> "do my homework for me"
2017-11-20T15:24:54 < rajkosto> he has clearly used it since he knows it all
2017-11-20T15:25:12 < dongs> DP1RD20JQ2-R1 for reverse and literally a dozen for standard
2017-11-20T15:25:49 < dongs> jae has fucking hell digikey still has me banned

2017-11-20T15:26:27 < kakimir> digikey ban? how do you get one?
2017-11-20T15:26:31 < dongs> kakimir: not sure
2017-11-20T15:26:33 < dongs> i think its by IP
2017-11-20T15:26:59 < kakimir> tagged as troublematic client?
2017-11-20T15:27:11 < dongs> my other office with another IP can access it fine
2017-11-20T15:27:14 < dongs> but on same class C
2017-11-20T15:27:17 < aandrew> lolwut
2017-11-20T15:27:18 < kakimir> so did you VPN?
2017-11-20T15:27:21 < aandrew> dongs: you got banned from digikey??
2017-11-20T15:27:21 < dongs> so im guessing i did something really bad
2017-11-20T15:27:24 < dongs> yea
2017-11-20T15:27:33 < aandrew> wtf how the hell did you manage that?

2017-11-20T15:28:03 < dongs> but its been liek 3 days
2017-11-20T15:28:18 < kakimir> you harrashed them for sure?
2017-11-20T15:28:30 < dongs> any computer/phone in my place = ban, another IP a couple digits off same class C = OK
2017-11-20T15:28:53 < aandrew> we need a quote bot
2017-11-20T15:28:58 < aandrew> that's one for the archives
2017-11-20T15:29:14 < dongs> i'm curious to find out waht the problem is
2017-11-20T15:29:34 < aandrew> just call up the local office and start cursing in japanese
2017-11-20T15:29:34 < rajkosto> dongs, i love when these pdfs have bitmapped diagrams i cant zoom into
2017-11-20T15:29:50 < dongs> rajkosto: displayport pinout is standartized
2017-11-20T15:30:06 < rajkosto> im clearly gonna need 3d models for these :P
2017-11-20T15:30:09 < dongs> the reverse one just moves the 20pins mirrored across axis
2017-11-20T15:30:14 < dongs> they exist, jae has them
2017-11-20T15:30:17 < dongs> and TE

2017-11-20T15:43:55 < kakimir> beautiful*
2017-11-20T15:44:22 < kakimir> make it as simple as possible
2017-11-20T15:44:40 < Ultrasauce> why use manhattan-style construction when you can go full harlem
2017-11-20T15:45:37 < aandrew> haha
2017-11-20T15:46:12 < aandrew> I agree with kakimir on this: super sensitive radio stuff usually has this kind of construction. minimizes capacitance and shitloads of shielding
2017-11-20T15:53:14 < aandrew> done right it really can look great
2017-11-20T15:56:18 < rajkosto> how does the "cardboard" one work ?!
2017-11-20T15:56:22 < rajkosto> what material is that
2017-11-20T15:58:45 < kakimir> is it blink competititon entry?

2017-11-20T16:16:57 < Ultrasauce> transient analysis
2017-11-20T16:17:03 < Thorn> wtf https://www.keysight.com/upload/cmc_upload/CLP_HHSkin2.jpg
2017-11-20T16:19:01 < dongs> needs pokemon
2017-11-20T16:23:32 < kakimir> when you click analysis it generates that directive
2017-11-20T16:23:46 < kakimir> 0.01 is 10milliseconds
2017-11-20T16:24:05 < kakimir> startup means power supplies start from 0volts
2017-11-20T16:24:13 < kakimir> trans means type of analysis
2017-11-20T16:24:23 < kakimir> tran*
2017-11-20T16:25:00 < tomeaton17> Ok thanks for the explanation
2017-11-20T16:25:10 < kakimir> it's like the most basic type of analysis where circuit is being run for certain time and you can see stuff happen in time axis
2017-11-20T16:25:36 < kakimir> .ic directive means initial condition
2017-11-20T16:25:48 < kakimir> so I make sure cap is at 0% charge
2017-11-20T16:26:26 < kakimir> by setting all potentials to 0
2017-11-20T16:27:19 < kakimir> there is some logic how those caps initial condition is set when no directives state it but usually it goes weird
2017-11-20T16:29:39 < kakimir> LTspice is free you should try it
2017-11-20T16:29:49 < kakimir> replicate that desing for example
2017-11-20T16:31:12 < kakimir> it's user interface is notorious for it's own rules how everything is done
2017-11-20T16:31:29 < kakimir> just to warn you

2017-11-20T16:47:40 < zyp> tomeaton17, why not? it's obvious
2017-11-20T16:48:18 < zyp> if a voltage regulator is getting hot and you're measuring no voltage on the output rail, the output rail is shorted
2017-11-20T16:48:43 < tomeaton17> zyp: Its not the voltage regulator
2017-11-20T16:49:50 < zyp> I'm talking about the voltage regulator in the BQ

2017-11-20T17:03:15 < dongs> cuz hes cheap
2017-11-20T17:03:19 < dongs> QFN was too expensive
2017-11-20T17:03:20 < englishman> arent they more expensive
2017-11-20T17:03:24 < dongs> and not hand solderable
2017-11-20T17:03:29 < englishman> yeah they totally are
2017-11-20T17:03:31 < englishman> its not lga
2017-11-20T17:03:41 < englishman> you save some vias i guess
2017-11-20T17:03:47 < dongs> my new mobo has RGB led connector...
2017-11-20T17:04:02 < dongs> .. which is 4 pins, and just outputs R,G,B 12V PWM'd and GND
2017-11-20T17:04:04 < zyp> didn't you tweet about that last week?
2017-11-20T17:04:07 < englishman> ^
2017-11-20T17:04:10 < dongs> sorry.
2017-11-20T17:04:12 < dongs> anyway
2017-11-20T17:04:15 < dongs> isnt that kinda noisy shit
2017-11-20T17:04:20 < dongs> why keep it around motherboard??
2017-11-20T17:04:31 < zyp> haha
2017-11-20T17:04:35 < dongs> switching 12V of ~some amps of current
2017-11-20T17:04:39 < dongs> at whatever shit
2017-11-20T17:04:44 < dongs> cant be GOOD right?
2017-11-20T17:05:02 < englishman> wouldnt they switch at 16khz tho
2017-11-20T17:05:10 < zyp> there's so much noisy shit in a modern computer that it can hardly make a difference
2017-11-20T17:05:12 < dongs> does that make it less bad
2017-11-20T17:05:13 < englishman> or something like that
2017-11-20T17:05:16 < dongs> ok
2017-11-20T17:05:36 < englishman> probably less noisy than 800khz ws2812b
2017-11-20T17:06:15 < dongs> is there a lunix flashfs i can use for write-once logging
2017-11-20T17:06:21 < dongs> that doesnt care about spi flash page size
2017-11-20T17:06:37 < dongs> like ,i erase a page then keep writing stuff to it until its full, go to next page etc
2017-11-20T17:06:44 < dongs> something that isnt a filesystem but i can read back later
2017-11-20T17:06:50 < zyp> does flash page size matter for write-once?
2017-11-20T17:06:56 < dongs> no, thats my point
2017-11-20T17:07:13 < zyp> tar?
2017-11-20T17:07:20 < dongs> er comeon
2017-11-20T17:07:24 < dongs> tar on stm32?
2017-11-20T17:08:14 < zyp> I haven't looked into the specifics, but from my understanding it should work nicely for write-once shit
2017-11-20T17:08:31 < zyp> and then you can just dump the flash into a file and extract it with any common utility
2017-11-20T17:09:42 < Ultrasauce> yeah that actually sounds like a good idea since you dont need runtime random access
2017-11-20T17:09:48 < Ultrasauce> literally what the format was designed for
2017-11-20T17:11:25 < englishman> heh
2017-11-20T17:11:36 < englishman> yeah isnt it tape archive
2017-11-20T17:11:40 < englishman> not the compressed one
2017-11-20T17:11:56 < dongs> i wannna have something to log errrors over potentially long days/months/etc time period
2017-11-20T17:12:28 < zyp> just a single logfile? why would you even need a FS for that?
2017-11-20T17:13:06 < englishman> make the errors fixed length and just keep pointer?
2017-11-20T17:14:15 < dongs> zyp, i donno
2017-11-20T17:14:24 < dongs> whwere would i keep pointer?
2017-11-20T17:14:37 < dongs> have a page for 'pointers' and lookup latest one by index?
2017-11-20T17:14:51 < Thorn> is bmp280 hand solderable?
2017-11-20T17:14:52 < dongs> (and erase page and start over when it rolls over page size
2017-11-20T17:14:57 < dongs> Thorn: with hotair sure
2017-11-20T17:15:04 < englishman> Thorn: yes
2017-11-20T17:15:13 < zyp> if unwritten flash is cleared, you could just do a binary search for the start of cleared flash
2017-11-20T17:15:25 < Thorn> good
2017-11-20T17:18:53 < Ultrasauce> eh maybe tar is unsuitable, 512 byte header and minimum file size
2017-11-20T17:20:48 < dongs> gross
2017-11-20T17:20:59 < dongs> yeah ionyl need to log liek 64 bytes of data during an error
2017-11-20T17:21:08 < dongs> which is entire systems state dump

2017-11-20T19:19:53 < qyx> maybe it was git addded before with half-way changes

2017-11-20T20:00:37 < kakimir> buzz
2017-11-20T20:01:11 < kakimir> I wonder if placing minimal lenght cord would remove it

2017-11-20T20:01:41 < Fleck> 10m unbalanced works from phone to PA Amp no buzz
2017-11-20T20:01:45 < kakimir> it has 6,35mm mono plugs instead of stereo plugs
2017-11-20T20:02:10 < Fleck> it just needs to be shielded

2017-11-20T20:02:29 < kakimir> it has quite sensitive inputs
2017-11-20T20:03:17 < Fleck> so ground loop problem?

2017-11-20T22:53:34 < Fleck> what's in your collection zyp?
2017-11-20T22:53:48 < zyp> uh
2017-11-20T22:54:17 < zyp> f0, f072, f3, f4, f7, l1, l0
2017-11-20T22:54:36 < zyp> might be forgetting some as well, I've lost track
2017-11-20T22:54:48 < Fleck> how much for f7? :P
2017-11-20T22:55:25 < zyp> probably not worth it for me to sell it
2017-11-20T22:55:54 < zyp> could be nice to have if I ever want to prototype some f7 shit
2017-11-20T22:57:53 < Fleck> true, just, don't prototype shit... prototype good stuff
2017-11-20T22:58:10 < zyp> :)
2017-11-20T23:16:37 < jadew> I don't like it
2017-11-20T23:17:04 < jadew> only a couple of IOs
2017-11-20T23:17:57 < jadew> on the bottom side of the board...
2017-11-20T23:18:38 < zyp> yeah
2017-11-20T23:19:16 < jadew> the LCD is glued in, is there a connector behind it or did they solder the FFC cable?
2017-11-20T23:20:00 < zyp> doesn't it go through the board?
2017-11-20T23:20:04 < jadew> when I saw the pictures, I thought the little FFC connector on the side was for its own display, so you could unplug that and plug a different one
2017-11-20T23:20:07 < jadew> no
2017-11-20T23:20:19 < jadew> it's connected beneeth the LCD
2017-11-20T23:22:41 < jadew> I hope I can remove it without breaking it
2017-11-20T23:26:02 < karlp> yeah, teh later discos got more and more into "here's a thing that you do a few things we prepared ahead of time, but not much else, so we built a nucleo line as well"
2017-11-20T23:27:13 < jadew> it's useless for what I need
2017-11-20T23:27:24 < karlp> so why did you buy it?
2017-11-20T23:27:32 < jadew> I thought it isn't
2017-11-20T23:27:40 < karlp> you could have read the user manual first...
2017-11-20T23:27:52 < jadew> the F4 discovery was so nice, I didn't expect this to be like that
2017-11-20T23:32:50 < jadew> why would they make them like that?
2017-11-20T23:32:52 < jadew> useless
2017-11-20T23:32:56 < Fleck> you can remove it... cut those doubleside tapes
2017-11-20T23:33:16 < Fleck> and then desolder
2017-11-20T23:38:42 < jadew> I just realized, it has a fucking arduino header
2017-11-20T23:38:46 < jadew> fucking shit

2017-11-20T23:39:42 < karlp> you seriously didn't read a damn thing, and just bought something?
2017-11-20T23:39:46 < jadew> yeah
2017-11-20T23:39:55 < jadew> I assumed it's a fucking dev board
2017-11-20T23:39:58 * karlp laughs and sticks his tongue out
2017-11-20T23:39:59 < karlp> it is.
2017-11-20T23:40:00 < jadew> not a retarded toy
2017-11-20T23:40:06 < karlp> for all the things you can develop on it,
2017-11-20T23:40:13 < karlp> you are so narrow minded sometimes :)
2017-11-20T23:40:26 < jadew> it's not flexible enough
2017-11-20T23:40:32 < jadew> I can't attach my own shit to it
2017-11-20T23:40:38 < jadew> my own little circuit
2017-11-20T23:40:54 < jadew> how can I possibly know if this piece of shit IC will work with my hardware, if I can't fucking connect to it?
2017-11-20T23:41:20 < jadew> am I supposed to always use this tiny LCD and those exact components?
2017-11-20T23:41:31 < jadew> the F4 discovery did it right
2017-11-20T23:41:59 < jadew> you had a bunch of stuff already on board and shitload of IOs exposed, including ones that were connected to components on the board (that you could disconnect)
2017-11-20T23:42:05 < jadew> this is just a demo board
2017-11-20T23:43:22 < jadew> and to add insult to injury they added a fucking arduino header
2017-11-20T23:43:33 < jadew> "here, connect some shields"
2017-11-20T23:47:01 < jadew> it has only 22 IOs exposed...

2017-11-21T03:36:02 < englishman> and upgrdman will continue to be wrong
2017-11-21T03:36:26 < jadew> I do both things
2017-11-21T03:36:39 < jadew> by default, no {} around single line blocks
2017-11-21T03:37:14 < jadew> I only use {} around single line blocks if it makes it more readable
2017-11-21T03:37:20 < jadew> say, if it's a multi-line if condition
2017-11-21T03:38:57 < jadew> and you can't mess it up, if you have proper indentation and if you don't use statements on the same line with the condition
2017-11-21T03:39:18 < jadew> if you do, you'd be used to having non indented lines after an if
2017-11-21T03:39:57 < jadew> but if you don't, you won't, and a non indented statemetn after an if will be obvious
2017-11-21T03:42:16 < dongs> < aandrew> I do it because it's far too easy to have an indentation fuckup
2017-11-21T03:42:18 < dongs> incorrect

2017-11-21T14:50:10 < Ultrasauce> not advocating for it, just wondering
2017-11-21T14:50:21 < Ultrasauce> cause i have a big ol tape of them i got for like a penny each
2017-11-21T14:50:31 < karlp> yeah, htat's about their only advantage :)
2017-11-21T14:51:33 < karlp> also, requires a full 10uF on output
2017-11-21T14:51:40 < karlp> and has a min load requirement of 2mA.
2017-11-21T14:51:58 < englishman> wut
2017-11-21T14:52:08 < karlp> I mean, yay, it can take 15V in, but ... big deal?

2017-11-21T14:52:54 < karlp> presumably, but if you're going to have a clone part number, are you going to have completely different specs?
2017-11-21T14:53:06 < Ultrasauce> haha ams1117 is even worse
2017-11-21T14:53:21 < karlp> I'm quoting from the LD1117 from ST, I don't imagine the clones are going to be substantially _better_

2017-11-21T15:00:20 < englishman> heh
2017-11-21T15:00:25 < Thorn> there was an appnote
2017-11-21T15:00:47 < Thorn> the 1st gen of PNP based LDOs were unstable with too low ESR
2017-11-21T15:01:17 < Thorn> years later they added a resistor to the error amp and created a zero to push the pole out of RH side or something
2017-11-21T15:01:33 < Thorn> started adding a resistor in new designs
2017-11-21T15:01:54 < Thorn> if you're using an early LDO you need to create that zero by supplying enough ESR
2017-11-21T15:02:30 < Thorn> btw newer Ta have much lower ESR, <<1Ω
2017-11-21T15:02:36 < Thorn> may not be enough lol
2017-11-21T15:05:36 < karlp> just read a note from kemet, "Can ESR Be Too Low? - Kemet"
2017-11-21T15:05:57 < karlp> also mentions 1000pF in parallel with the voltage dividers can work as well, without raising esr
2017-11-21T15:06:12 < karlp> so, take away result? don't use shitty old LDOs!
2017-11-21T15:06:27 < Thorn> tl;dr it took them years to come up with a 1 resistor fix
2017-11-21T15:06:40 < Thorn> >control theory
2017-11-21T15:06:55 < karlp> alternatively, they didn't hve any parts taht had low enough esr that it mattered, and when it did, the control nerds that justified the original design had retired

I need to match coordinates between two accels running at the same time but I'm fucking something up with the calculation of pitch/roll angles because the rot matrix doesnt make the 2nd measure be == the 1st

2017-11-21T18:17:32 < Laurenceb> how rotation formed
2017-11-21T18:17:36 < aandrew> c10ud: first things first: stop trying to do math with Euler angles
2017-11-21T18:17:47 < zyp> you just want to find the angle?
2017-11-21T18:18:01 < aandrew> c10ud: they are not suited for this. the order you apply them and gimball lock will fuck you every time
2017-11-21T18:18:05 < c10ud> lol
2017-11-21T18:18:05 < c10ud> it's a rotation matrix, so there are three angles
2017-11-21T18:18:15 < zyp> no
2017-11-21T18:18:15 < c10ud> but I think I can skip one since there's gravity
2017-11-21T18:18:26 < zyp> and you can't make a rotation matrix
2017-11-21T18:18:33 < c10ud> Laurenceb, rot is 3x3
2017-11-21T18:18:45 < aandrew> I thought rot was 4x3
2017-11-21T18:18:59 < Laurenceb> the timecube has 4 sides
2017-11-21T18:19:07 < aandrew> lol
2017-11-21T18:19:08 < Laurenceb> so that makes sense to me
2017-11-21T18:19:24 < c10ud> zyp, why not? interpolating absolute accels should let me get the angles
2017-11-21T18:19:27 < Laurenceb> always remember, top and bottom are NOT sides
2017-11-21T18:19:39 < zyp> c10ud, because you don't have enough information

2017-11-21T18:20:09 < zyp> c10ud, you have two direction vectors, but you don't know anything about the rotation around that vector
2017-11-21T18:21:29 < c10ud> zyp, I think the caveat is that while standing still one vector equals g hence it's rotation matrix is {1,0,0}{0,1,0}{0,0,1} (e.g. angle is 0)
2017-11-21T18:21:35 < c10ud> at least that's how I got it
2017-11-21T18:21:56 < zyp> c10ud, you're missing my point
2017-11-21T18:22:38 < zyp> I'm assuming steady state, so you're only measuring gravitational acceleration
2017-11-21T18:23:21 < zyp> this will give you a vector that's pointing straight up in the world reference frame
2017-11-21T18:23:27 < c10ud> yes, ok
2017-11-21T18:24:12 < zyp> each of the accelerometers will give you an absolute up-vector, seen from its own reference frame
2017-11-21T18:24:31 < zyp> which means each device will know where up is

2017-11-21T18:25:57 < c10ud> ah I think I see what you mean now
2017-11-21T18:26:17 < zyp> so you simply doesn't have enough information to construct a matrix that translates from one device's reference frame to the other's
2017-11-21T18:26:40 < c10ud> btw: in the end I only need a differential measurement between the same axe on the two different devices (not the earth gravity axis), I just need to account for pre-existing differences in e.g. mounting

2017-11-21T18:27:16 < zyp> that's easy

2017-11-21T18:32:56 < c10ud> I need to try this I guess
2017-11-21T18:35:34 < zyp> anyway, dot product will give you cos of the angle, abs of cross product will give you sin of the angle
2017-11-21T18:35:47 < zyp> grab both and plug them into atan2 and you'll have your angle
2017-11-21T18:36:58 < zyp> this assumes both vectors are normalized, so do that first

2017-11-21T18:39:33 < tr0ubl3> For the people that were helping me with my board troubles yesterday, It seems to be powering on now I didnt solder the cap correctly last time. However I need some bodge wires and will probably redesign it using bigger than 0603
2017-11-21T18:40:16 < zyp> c10ud, you'll want both
2017-11-21T18:41:21 < zyp> a cross b = |a| |b| sin(phi) n
2017-11-21T18:41:53 < zyp> |a| and |b| are 1 since your vectors are normalized, and |n| is also 1

2017-11-21T18:42:20 < DelvingDeeper> Anyone have experience with FATFS on the stm32?
2017-11-21T18:42:22 < zyp> a dot b = |a| |b| cos(phi)
2017-11-21T18:42:46 < zyp> and since they are still 1, = cos(phi)
2017-11-21T18:43:16 < zyp> plug both results into atan2 to get the angle

2017-11-21T19:21:50 < Rob235> thanks
2017-11-21T19:24:26 < karlp> Thorn: what are you talking about?
2017-11-21T19:24:52 < Thorn> rs-485 unit load
2017-11-21T19:25:14 < Thorn> i.e. standard receiver input impedance
2017-11-21T19:26:07 < Thorn> the standards requires the bus to work if there are no more than 32 unit loads on it
2017-11-21T19:26:23 < karlp> right....
2017-11-21T19:26:27 < zyp> old standard, perhaps?
2017-11-21T19:26:41 < Thorn> and cheap dongs-approved max485 has exactly that input impedance, 12kΩ

2017-11-21T19:29:41 < Thorn> and why are max parts crazy
2017-11-21T19:29:48 < karlp> because they're expensive for no value add?
2017-11-21T19:30:01 < karlp> unles you get max485 parts the same price as ld1117 parts ;)
2017-11-21T19:31:34 < Thorn> I got 100 max485 and 100 max3485 from aliexpress very cheap. probably counterfeit lol
2017-11-21T19:32:16 < karlp> yes, quite likely :)
2017-11-21T19:33:21 < Thorn> of course low load / slew rate limited etc. parts aren't that cheap but there is a range of max parts with seemingly the same features as ISL ones
2017-11-21T19:34:08 < karlp> slew rate limited / not limited is just "fast/slow"
2017-11-21T19:34:15 < karlp> and yes, they all have the same set of options really,

2017-11-22T00:40:51 < englishman> did braindamage get hacked
2017-11-22T00:40:58 < englishman> or /parted in embarrassment
2017-11-22T00:41:49 < Thorn> at least it wasn't furries
2017-11-22T00:42:05 < Thorn> To protect the application against spurious write access or system hang-up, possibly caused by electromagnetic disturbance, the most critical registers are implemented as two bitfields that must contain complementary values.
2017-11-22T00:42:10 < Thorn> Mismatches are automatically detected by this mechanism, triggering an EMC reset and allowing the application to cleanly recover normal operations.

2017-11-22T02:03:59 < kakimir> that's stupid
2017-11-22T02:04:30 < Laurenceb_> hmm no I dont think so
2017-11-22T02:04:43 < Laurenceb_> ltspice is built to be batch based
2017-11-22T02:04:51 < Laurenceb_> why would you want real time?
2017-11-22T02:05:54 < kakimir> no actual reason
2017-11-22T02:06:12 < kakimir> to emulate user inputs easily?
2017-11-22T02:07:32 < sync> it is not made for that?

2017-11-22T02:25:16 < kakimir> okay it's not possible to create combined pmos reverse protection and power switch
2017-11-22T02:25:27 < kakimir> for simple reason
2017-11-22T02:25:41 < kakimir> body diode
2017-11-22T02:25:54 < kakimir> it took me a while to simulate
2017-11-22T02:26:11 < kakimir> and just one minute to understand
2017-11-22T02:26:50 < kakimir> to say I need 2 pmos transistors
2017-11-22T02:27:02 < kakimir> one dedicated reverse protection
2017-11-22T02:27:09 < kakimir> one dedicated power switch
2017-11-22T02:30:27 < kakimir> I wonder how I could do power switch that doesn't virtually use any current
2017-11-22T02:30:35 < kakimir> in this configuration
2017-11-22T02:32:13 < kakimir> VIN is 3-17V and power switch output max 5.5v
2017-11-22T02:32:27 < kakimir> *comparator output for power switch
2017-11-22T02:32:45 < kakimir> low or high level active is free to choose
2017-11-22T02:41:09 < kakimir> only thing I see possible is NMOS grounding fet for PMOS power switch
2017-11-22T02:41:18 < kakimir> that will use power
2017-11-22T02:41:52 < kakimir> require very low leakage nmos
2017-11-22T02:46:15 < kakimir> sure adding some megaohms brings it down to reasonable level
2017-11-22T02:46:59 < kakimir> that should be lower than comparator power consumption or regulator Iq
2017-11-22T02:47:31 < kakimir> capacitor is required for sure for gate

2017-11-22T03:37:44 < branjb> why does pixhawk have two imu?
2017-11-22T03:41:05 < aandrew> twice as many quaternions
2017-11-22T03:48:08 < Thorn> so I have a board with a mcu and a couple of sensors that will consume 5mA max, and it needs to be powered from 12...24V
2017-11-22T03:48:43 < Thorn> but it will also have rs-485, and that is 90...250mA more so I can't use an LDO
2017-11-22T03:49:57 < Thorn> at least a small one such as TPS70933
2017-11-22T03:50:35 < Thorn> and I don't want to put a puck reg either because it will make the pcb 2x as large
2017-11-22T03:50:39 < Thorn> what do

2017-11-22T03:51:56 < englishman> thought it bounced off
2017-11-22T03:52:33 < Thorn> I will need a 250mA 30V ldo and max power dissipation will be 27V*0.25A = almost 7W

2017-11-22T11:38:07 < ohsix> wont wear glasses when they can't see, won't wear hearing aids when they can't hear; and your'e constantly compensating for shit they won't do
2017-11-22T11:38:25 < ohsix> and they play up not being able to see or hear to their benefit, by acting confused
2017-11-22T11:39:46 < tr0ubl3> How would you guys do this. I have a system that monitors battery conditions on up to 8 batteries. Each battery gets its own stm32. How could I collect the data from all the devices and collate it? I was thinking i2c due to the number of devices but I am not sure
2017-11-22T11:40:29 < ohsix> are there less than 127 devices? is assigning them bus addresses going to be a problem?
2017-11-22T11:40:55 < karlp> Thorn: we're using tps70933 on our rs485 boards, powering with 24V at 55C, with ~12mA on the board itself. you're doing your maths wrong?
2017-11-22T11:41:43 < karlp> the bias resistors are powered by the end with the bias resistors, on the master, not on each slave.
2017-11-22T11:42:04 < ohsix> if all the devices are cooperating you can do silly stuff like have devices respond to the same bus id based on the register you're reading but that'd be really smelly
2017-11-22T11:42:05 < tr0ubl3> ohsix: I will be interfacing with stm32s so I assume I can change the address. And yes there will be less than 127.
2017-11-22T11:44:19 < ohsix> daisy chain with a massive bit string to shift through
2017-11-22T11:45:19 < karlp> rs485 is the topic of the day tr0ubl3, it would work too
2017-11-22T11:45:33 < karlp> possibly better than i2c/spi if you're going between battery packs
2017-11-22T11:46:30 < Thorn> karlp: my max485 datasheet says something like up to 90 or 95 mA when tx, up to 250 when bus is shorted
2017-11-22T11:47:03 < karlp> are you driving 10Mbz square waves?
2017-11-22T11:47:16 < Thorn> 115.2k only
2017-11-22T11:48:18 < qyx> tr0ubl3: if those stm32s do not have common gnd, you will need to shift levels somehow
2017-11-22T11:49:03 < qyx> some rs485 transceivers with wide common mode voltage range can be used
2017-11-22T11:49:46 < qyx> or a current loop as LT does with its monitors
2017-11-22T11:49:46 < tr0ubl3> Ok, this is going to be a bit more complex than I thought :/
2017-11-22T11:50:20 < qyx> or maybe usarts connected with a cap
2017-11-22T11:50:27 < qyx> or a optocoupler if you feel ghetto enough
2017-11-22T11:54:00 < karlp> Thorn: I see what you're getting at, but.... (and you may not like it) tps709 enters thermal shutdown, hsot cpu dies, stops trying to drive DE, driver short circuit goes away....
2017-11-22T11:54:18 < karlp> treat it as a software bug
2017-11-22T11:54:27 < tr0ubl3> rs485 looks good, or could get an stm32 with 8 usart periphs
2017-11-22T11:55:12 < ohsix> with one
2017-11-22T11:55:58 < ohsix> https://en.wikipedia.org/wiki/RS-485 -> network topology

2017-11-22T11:56:43 < ohsix> NUH UH I AM OLD AND HAVE BAD EYESIGHT
2017-11-22T11:57:02 < ohsix> also seemed like a non sequitur, but yea missed or
2017-11-22T11:57:38 < Thorn> karlp: the funny thing is, there will be a BMP/E280 1-2 cm from that LDO. I don't want it heating up, even if just a little
2017-11-22T11:58:14 < Thorn> (24-3.3) * a few mA is still ~1W
2017-11-22T11:58:29 < Thorn> er 0.1W
2017-11-22T11:58:33 < Thorn> but still
2017-11-22T11:58:38 < karlp> yes, surprise surprise 24V and LDOs aren't a good match
2017-11-22T11:59:03 < karlp> we went with a tps709 because it _could_ work thermally, and we didnt' have to go and requalify things with a switcher, though I really wanted to put one on.
2017-11-22T11:59:04 < ohsix> use multiple 2033 pass transistors and 5kg of aluminum
2017-11-22T11:59:06 < tr0ubl3> Is additional hardware required for rs485?
2017-11-22T11:59:15 < dongs> just the tranceiver
2017-11-22T11:59:24 < dongs> you could also use CAN...
2017-11-22T11:59:37 < karlp> (which also needs a transceiver)
2017-11-22T12:00:51 < ohsix> spi daisy chain
2017-11-22T12:02:00 < qyx> newer stms have that single wire interface thing

2017-11-22T12:03:13 < qyx> SWP (single wire protocol)

2017-11-22T12:04:13 < ohsix> does it share similarities with swd
2017-11-22T12:04:51 < qyx> no, it is true single wire as opposed to swd

2017-11-22T12:05:48 < ohsix> 'swpmi' is cute
2017-11-22T12:06:19 < qyx> don't know, but it is weird, uses voltage mode to transmit master->slave
2017-11-22T12:06:24 < qyx> and current mode to transmit back
2017-11-22T12:06:26 < ohsix> The Single Wire Protocol (SWP) is a specification for a single-wire connection between the SIM card and a near field communication (NFC) chip in a cell phone. It is currently under final review by the European Telecommunications Standards Institute (ETSI).[1][2]

2017-11-22T15:48:33 < karlp> yeah, I'm not real impressed by the part really, needs diode and coil and dividers and allthe caps
2017-11-22T15:49:04 < karlp> compared to some of the AO fets we've got listed in zypsnips 450mohm isn't really very impressive

2017-11-22T15:49:53 < Thorn> same 1.2A etc.
2017-11-22T15:49:56 < karlp> oh weird,
2017-11-22T15:49:59 < Thorn> where did you see 600mA?
2017-11-22T15:50:07 < karlp> I got linked to a AOZ1282CI-1 part from their website
2017-11-22T15:50:26 < karlp> http://www.aosmd.com/products/power-ics/ezbuck-dc-dc-buck-regulators/AOZ1282CI-1
2017-11-22T15:50:27 < dongs> i used one of 128x series in something
2017-11-22T15:50:29 < dongs> or maybe englishman did
2017-11-22T15:50:32 < dongs> i used a MPS part instead

2017-11-22T15:55:00 < karlp> who knows what the differnce between ao3400 and ao3400a is? I can't find anything different in the datasheets at all
2017-11-22T15:55:38 < dongs> Thorn: looks like some rageberrypi shield
2017-11-22T15:55:45 < dongs> made in eagle
2017-11-22T15:55:46 < dongs> thus trash
2017-11-22T15:55:47 < Thorn> I think I ordered 3400 from ali and got 3400a instead
2017-11-22T15:56:11 < Thorn> no idea as to the difference but much cheaper than irlml lol
2017-11-22T15:56:48 < zyp> karlp, what do you mean can't find anything different? 3400a has slightly lower R_DSon
2017-11-22T15:57:06 < zyp> 28 vs 26.5
2017-11-22T15:57:58 < karlp> oh right, 3400(a) have differences
2017-11-22T15:58:05 < karlp> 3401(a) (p channel) have no differences

2017-11-22T18:39:30 < aandrew> it only leads to confusion down the road. to the side is also acceptable, but still ick.
2017-11-22T18:39:34 < aandrew> (this is all personal opinion BTW)
2017-11-22T18:39:47 < aandrew> What isn't personal opinion though is the lack of a pullup on the RST# line
2017-11-22T18:39:49 < BrainDamage> i draw PE symbols pointing up, because first world anarchist
2017-11-22T18:40:25 < aandrew> nothing else obviously wrong on the STM32 area, although I did not verify that you've connected the I2C lines to pins actually capable of going to the I2C peripheral, same iwth SWD
2017-11-22T18:41:05 < qyx> aandrew: lol gnd
2017-11-22T18:41:07 < tr0ubl3> Yeah when I managed to flash it the i2c worked.
2017-11-22T18:41:19 < aandrew> but yes, in general this is a schematic drawn by a newb. Nothing wrong with that, but if you are interested in drawing better schematics I can offer some critique
2017-11-22T18:42:04 < zyp> aandrew, external pullup isn't required
2017-11-22T18:42:26 < invzim> thank god for git, spi1 used to work but got broken in the last 40 commits or so while I was struggling with sdio and spi2
2017-11-22T18:42:31 < aandrew> zyp: I don't care what is and isn't required, it's good practise not to rely on the internal pullup unless you have good reason
2017-11-22T18:42:52 < zyp> smaller BOM is good enough reason for me
2017-11-22T18:42:53 < tr0ubl3> Yes
2017-11-22T18:43:00 < aandrew> also I'd add 100nf decoupling on both VDDA and VDD (basically you should have 1uf+100nf on every VDD pin
2017-11-22T18:43:05 < tr0ubl3> I am definitely a noob.
2017-11-22T18:43:13 < aandrew> zyp: unless you're making 10k+ that shouldn't even be on your radar
2017-11-22T18:43:22 < qyx> zyp: I have one board which resets every time I touch the debug connector
2017-11-22T18:43:28 < aandrew> no decoupling on the LD1117
2017-11-22T18:43:40 < tr0ubl3> Yeah I know about that, I realised that before I got the board
2017-11-22T18:43:40 < zyp> aandrew, thinking more about board area
2017-11-22T18:44:19 < qyx> then I started adding pullup to the nrst line
2017-11-22T18:44:25 < karlp> aandrew: no need for pullup on rst
2017-11-22T18:44:31 < aandrew> again, unless it's critical the size of an 0805 isn't worth concerning yourself over. I'd much rather have a board that is a little overdone than early-optimizing the shit out of things and wondering
2017-11-22T18:44:33 < karlp> cap to ground recommended only
2017-11-22T18:44:38 < aandrew> karlp: yeah zyp already told me :-)
2017-11-22T18:45:03 < aandrew> you don't appear to be concerned with analog signal fideltiy so VDDA connected directly to VDD is fine
2017-11-22T18:45:25 < tr0ubl3> Yeah I am not using the internal adc
2017-11-22T18:45:41 < karlp> qyx: do you have the cap to ground on rst?
2017-11-22T18:45:44 < aandrew> tr0ubl3: I always put 100 ohms in series with my UART lines because you just know you're gonna fuck up the direction (TX-TX or RX-RX) and the resistors make really handy ways to break the connection and fix it
2017-11-22T18:45:45 < tr0ubl3> Most of the work is done by U2 and I just get the info from that
2017-11-22T18:45:46 < karlp> or did you just add a pullup instead?
2017-11-22T18:45:56 < zyp> aandrew, I like making small boards: https://bin.jvnv.net/file/NjEyT.JPG

2017-11-22T18:47:51 < aandrew> zyp: I tend to make boards which are eas(ier) to debug/probe, at least in prototype phase: https://imgur.com/BI7v6Bc
2017-11-22T18:48:51 < qyx> so huge, much testpads
2017-11-22T18:48:54 < karlp> and you're certainly more pro, but sometimes you're as prone to cargo culting things like pullups on reset as anyone else is :)
2017-11-22T18:48:55 < Laurenceb> madness
2017-11-22T18:49:01 < aandrew> note the real SWD connector :-)
2017-11-22T18:49:49 < qyx> why do you use transistors to drive the leds?
2017-11-22T18:50:15 < tr0ubl3> Yeah the board I made for it is quite small and also probably awful design https://i.imgur.com/05Cshnl.jpg
2017-11-22T18:50:18 < aandrew> yeah for the cost of a sixth of a cent and the 2.4mm^2, I'll add the resistor. I can always DNP it
2017-11-22T18:50:51 < aandrew> qyx: they're dual mosfets and they're for voltage translation/unloading. some of the signals are 1.8V, some are 3.3V
2017-11-22T18:51:33 < aandrew> qyx: nice. antoher reccomendation: key that 0.100" connector because you know someone (maybe even you) is gonna connect it backward
2017-11-22T18:51:37 < tr0ubl3> so would you guess that there is a problem with the board layout if the schematic is fine?
2017-11-22T18:51:38 < qyx> I can see a white popcorn there
2017-11-22T18:51:42 < aandrew> ideally choose a pinout that will fail nicely when reversed
2017-11-22T18:53:27 < qyx> tr0ubl3: did you connect the ground?
2017-11-22T18:53:45 < aandrew> I make small boards too: http://mixdown.ca/dump/blerocket.jpg
2017-11-22T18:54:08 < tr0ubl3> qyx: Yeah I added in a bodge wire, and I managed to flash one of the previous boards but then accidentally shorted some pins and blew up the STM32. I soldered another one today and it doesnt flash at all.
2017-11-22T18:54:36 < qyx> maybe you blew up something else too
2017-11-22T18:54:51 < tr0ubl3> I soldered a completely new board

2017-11-22T19:09:26 < aandrew> do the supplies look right? Can the programmer see the STM32? How does current draw look? Anything getting hot? inspect carefully, under different light and different angles for shorts. Use a dental pick or toothpick and try to move each pin to make sure they're actually soldered down.
2017-11-22T19:09:53 < aandrew> that board looks pretty grimy - use an old toothbrush and regular old dish soap+water and give it a good scrub
2017-11-22T19:10:24 < aandrew> if that's not no-clean flux, you'll have to use something stronger (get a jug of 99% IPA from walmart for $3)
2017-11-22T19:11:00 < aandrew> there are so few components on that board and there is so much space between them that this should not take more than 10 minutes to do properly

2017-11-22T19:36:39 < aandrew> dont' bother with the camera. use your nose (literally touch your nose around the board) -- I find it's far more sensitive than my fingers
2017-11-22T19:38:14 < aandrew> general rule of thumb from my power electronics days: if you can hold your hand on it, it's below 40C
2017-11-22T19:41:11 < Rob235> should I go colorful with my website? someone choose a color scheme for me
2017-11-22T19:41:45 < aandrew> I say you should use at least three neon colors and combine with a lot of black outlining and a pastel background
2017-11-22T19:41:47 < qyx> you should use at least two colors preferably
2017-11-22T19:42:01 < emeryth> green on black
2017-11-22T19:42:08 < aandrew> red on blue
2017-11-22T19:42:15 < aandrew> keep it primary
2017-11-22T19:42:27 < aandrew> or blue on black is also good, just make sure the blue is really thin lined font
2017-11-22T19:42:39 < Thorn> attn karlp aoz1282ci is pin compatible with mcp16301t
2017-11-22T19:42:58 < qyx> all good suggestions have been said, I cannot add anything better
2017-11-22T19:43:10 < tr0ubl3> Ok its not getting hot at all
2017-11-22T19:43:55 < aandrew> try a pullup on that RST# line :-)
2017-11-22T19:44:09 < aandrew> is your debugger driving RST#?
2017-11-22T19:44:17 < Rob235> I had it all blue and black but now I'm testing out adding color to show what menu panel is open and I kinda like the added color, I just cant decide on which colors: https://imgur.com/a/OHju3
2017-11-22T19:45:41 < tr0ubl3> aandrew: I will give the pullup a go. Yes the debugger is but I think I remember last time I managed to get it to flash it wasn't connected. Here is the pcb for reference https://i.imgur.com/uT9JSyh.png
2017-11-22T19:47:17 < aandrew> there's some easy fixes to that board to help too
2017-11-22T19:47:25 < aandrew> but nothing that clearly is making it not work
2017-11-22T19:47:39 < aandrew> did you do the toothpick/dental pick test on the STM32? really it should come up right away
2017-11-22T19:47:44 < aandrew> what are you using for a debugger?
2017-11-22T19:48:49 < tr0ubl3> I am using the cheapo stlink things
2017-11-22T19:49:05 < tr0ubl3> I have to go now but I will try the things you said and report back later. Thanks!
2017-11-22T19:49:56 < aandrew> np, good luck. just be methodical

2017-11-22T20:32:51 < englishman> upgrdman: used a clear varnish with no stain for kitchen table. you can stain if you want. for a worksurface you might want something more sturdy like epoxy. tho it takes way more effort
2017-11-22T20:32:57 < englishman> sanding you can do 150->220
2017-11-22T20:33:18 < englishman> maybe used some teak oil before varnish
2017-11-22T20:33:28 < englishman> protects from UV some
2017-11-22T20:34:23 < englishman> varnish should be fine

2017-11-22T20:37:43 < englishman> here's bob vila to help you with your home improvement projects
2017-11-22T20:37:44 < englishman> https://www.bobvila.com/articles/varnish-vs-polyurethane/
2017-11-22T20:37:53 < englishman> polyurethane goes on clear and—in just one or two coats—cures into a scratch- and abrasion-proof hard plastic that is versatile enough for most indoor projects.
2017-11-22T20:38:14 < upgrdman> ok. sorry for all the q's. last q about wood: if im going to apply polyurethane, do i NEED to sand first, and how many coats should i apply? sand between coats?
2017-11-22T20:38:32 < upgrdman> *clicks*
2017-11-22T20:38:34 < englishman> well basically if you dont sand itl be ugly and lumpy
2017-11-22T20:38:37 < englishman> like drywall
2017-11-22T20:38:40 < upgrdman> ah
2017-11-22T20:38:49 < englishman> and you will regret the time and cost you spent on varnish
2017-11-22T20:38:51 < englishman> and redo it in a year
2017-11-22T20:39:04 < upgrdman> when sanding, do i just need to break the surface, or do i need to remove whatever coating ikea applied?
2017-11-22T20:40:03 < englishman> ikea claims to come bare. tho it might have a thin coating of jizz on it. you'll sand mainly to make it smooth
2017-11-22T20:40:09 < branjb> this info is relevant to me
2017-11-22T20:40:18 < upgrdman> k
2017-11-22T20:40:20 < englishman> you can varnish over whatever, but it'll look ugly if it isnt flat
2017-11-22T20:40:25 < branjb> should go in github words of wisdom
2017-11-22T20:40:25 < upgrdman> k
2017-11-22T20:40:46 < upgrdman> yes, because handling your wood is vital to ##stm32 patrons
2017-11-22T20:41:07 < branjb> it is
2017-11-22T20:41:43 < englishman> keep in mind im also noob
2017-11-22T20:42:12 < upgrdman> hmm. reading up on polyurethanes. a matte sheen sounds nice, or would that make the wood look fake as shit?
2017-11-22T20:45:16 < englishman> that's just the reflectivity of the finish
2017-11-22T20:45:29 < englishman> there might be samples at the store you can check out for yourself

2017-11-22T22:04:08 < Thorn> do you ever need a xtal for uart/rs-485?
2017-11-22T22:04:24 < Thorn> (because HSI is not accurate enough)
2017-11-22T22:05:21 < kakimir> I think conclusion was that rs232 allows whole range of error that HSI can throw at it
2017-11-22T22:05:40 < kakimir> it's only like under 10bits at time
2017-11-22T22:05:57 < kakimir> so if you look at this timeframe
2017-11-22T22:06:13 < kakimir> throw it off by your HSI error
2017-11-22T22:06:56 < karlp> Thorn: yeah, hsi is fine for ~anything uart based as far as I can tell
2017-11-22T22:07:01 < kakimir> place accurate clock pulses under this timeframing those clock pulses should be well within the timeframe constrants
2017-11-22T22:07:13 < karlp> we only added a crystal to our current rs485 devices for our new "magic science shit"
2017-11-22T22:07:21 < Thorn> I guess it would depend on whether all the devices on your bus are at the same temp
2017-11-22T22:07:45 < karlp> yeah, but even hsi over temp is still prettty much totally ok for most baud rates asiui
2017-11-22T22:09:07 < kakimir> but if there is 2 HSI devices with opposite maximum errors you need to check that case
2017-11-22T22:10:24 < Thorn> stm8s103 HSI is ±1% @5V & 25°C, ±2% @5V over the temp range, ±3% over Vcc & temp ranges
2017-11-22T22:10:25 < kakimir> I think once someone explained me the case when there is to say time accurate PC at another end
2017-11-22T22:10:49 < Steffanx> Better tell Atmel how to do proper RC oscillators.

2017-11-22T23:07:49 < jadew> don't know wtf happened but all the affordable T962A ovens got sold right when I decided to buy one
2017-11-22T23:08:04 < invzim> I hear they are poop
2017-11-22T23:08:06 < jadew> and now everything available on ebay is %50+ more expensive
2017-11-22T23:08:36 < jadew> invzim, I heard that once you replace the tape and make a few mods, it's fine
2017-11-22T23:09:02 < invzim> which runs quite a bit of time and money
2017-11-22T23:09:21 < jadew> not really, an hour or two
2017-11-22T23:09:28 < invzim> good luck :)
2017-11-22T23:09:38 < jadew> what do you suggest instead?
2017-11-22T23:10:02 < invzim> I got qs-5100, build quality is OK - haven't really used it, but the temperature controls seems very crappy after a couple of tests
2017-11-22T23:10:39 < invzim> some guy on eevblog said it just worked out of the box ,not my experience
2017-11-22T23:10:50 < jadew> heh
2017-11-22T23:10:52 < invzim> anyho - you can check it out if you haven't already
2017-11-22T23:11:09 < jadew> yeah, I've seen it
2017-11-22T23:12:45 < jadew> seems to be as small as the T962
2017-11-22T23:12:55 < jadew> I'm looking for the T962A, which is a bit bigger
2017-11-22T23:13:28 < jadew> 30x32 vs 18x23
2017-11-22T23:13:33 < jadew> (cm)
2017-11-22T23:13:35 < invzim> ali not an option?
2017-11-22T23:13:50 < invzim> <400usd with DHL shipping
2017-11-22T23:13:59 < jadew> yeah, was hoping for something in the EU
2017-11-22T23:14:16 < jadew> stuff from china takes a lot to get here and then there's the customs complication
2017-11-22T23:14:22 < invzim> I considered getting the 962(a) and pimping it with a kit, but meh
2017-11-22T23:14:26 < jadew> I try to avoid it for bigger things
2017-11-22T23:14:51 < invzim> not a problem in Norway, we get customs and tax on everything regardless :)
2017-11-22T23:15:38 < jadew> that's weird
2017-11-22T23:15:56 < invzim> what do you need it for? After actually having one, I think it's use it pretty limited
2017-11-22T23:16:12 < jadew> invzim, I want to start manufacturing some boards
2017-11-22T23:16:36 < invzim> china is le cheap, and assembly is going to be a PITA regardless
2017-11-22T23:16:58 < jadew> yeah, but I don't want to give china everything they need to clone my stuff
2017-11-22T23:16:58 < invzim> unless of course you get a p&p, but then your budget can probably cover something more fancy than the 962
2017-11-22T23:17:15 < jadew> I'll p&p by hand
2017-11-22T23:17:32 < jadew> I have a little suction pump that seems to work fine
2017-11-22T23:17:55 < jadew> a p&p machine would be great, but I'm not there yet
2017-11-22T23:18:03 < invzim> how many parts on the pcb you have in mind?
2017-11-22T23:18:21 < jadew> ~40
2017-11-22T23:18:26 < jadew> so not that many
2017-11-22T23:18:45 < invzim> yeah, there is a sweet spot there somewhere for that scale
2017-11-22T23:19:01 < invzim> current board I'm workin on has 157 and takes damn forever - oven or not
2017-11-22T23:19:24 < karlp> Thorn: stm32l1 runs at full speed form hsi too.
2017-11-22T23:20:14 < invzim> I may do bga one day, and then over will come in handy
2017-11-22T23:20:17 < invzim> oven
2017-11-22T23:21:19 < karlp> Thorn: you'r emixing onewire, i2c _and_ spi sensors? :)
2017-11-22T23:21:19 < BrainDamage> the problem of bga is not the soldering part, it's the defect check
2017-11-22T23:21:34 < Thorn> yes
2017-11-22T23:21:42 < BrainDamage> without an xray machine you cannnot be sure if it's a wiring defect or a software one
2017-11-22T23:21:48 < Thorn> I just got rid of an analog one
2017-11-22T23:21:53 < BrainDamage> it makes debug a nightmare
2017-11-22T23:22:13 < Thorn> so only 3 protocols l0lz
2017-11-22T23:22:18 * karlp grins
2017-11-22T23:22:31 < jadew> BrainDamage, do the cheap chinese assembly houses x-ray all the boards?
2017-11-22T23:22:50 < jadew> or do they just know that they have yield of x% and they're fine with that
2017-11-22T23:22:51 < BrainDamage> no, they just have the process down reliable enough the defect rate doesn't warrant it
2017-11-22T23:23:00 < jadew> I see
2017-11-22T23:23:07 < BrainDamage> they still take some statistical sampling for the boards
2017-11-22T23:23:25 < BrainDamage> but no 100% test coverage, to my knowledge
2017-11-22T23:23:44 < BrainDamage> the problem is that the moment you do a diy process, you won't know
2017-11-22T23:23:56 < BrainDamage> if all goes well, then good, you have np
2017-11-22T23:24:17 < BrainDamage> if you have problems, then you have the headache you need a way to distinguish hw faults from sw
2017-11-22T23:24:36 < BrainDamage> which is possible in some cases, but not always
2017-11-22T23:24:41 < jadew> you could have a good test setup and if you have good yield, you could just rely on that
2017-11-22T23:24:42 < Thorn> <BrainDamage> without an xray machine you cannnot be sure if it's a wiring defect or a software one <-- boundary scan?
2017-11-22T23:25:03 < BrainDamage> Thorn: boundary scan here would be equivalent to unit testing every single pin
2017-11-22T23:25:12 < Thorn> (it's still going to be a PITA even if it works)
2017-11-22T23:25:21 < BrainDamage> imagine if say, some psu pins don't get attached
2017-11-22T23:25:26 < BrainDamage> like those with the psu caps
2017-11-22T23:25:36 < BrainDamage> it'd still work, but in some workloads it'd glitch
2017-11-22T23:25:42 < BrainDamage> good fucking luck debug it
2017-11-22T23:26:33 < BrainDamage> or if the connection is unreliable as in it works, but only within certain temp ranges
2017-11-22T23:26:42 < BrainDamage> due to termal warping
2017-11-22T23:27:02 < BrainDamage> there's a lot of failure modes, again, if it all works, then you have np
2017-11-22T23:27:35 < BrainDamage> but when you have a fault, then you cannot always rule out hw fault, assume sw first, but it can potentially throw you into a goose chase

2017-11-22T23:32:34 < qyx> it was like 6K for them, except the NTC

2017-11-23T00:25:52 < kakimir> is there a way to do packet sniffing on router?
2017-11-23T00:26:02 < kakimir> run some server
2017-11-23T00:26:15 < BrainDamage> arp poisoning
2017-11-23T00:27:27 < kakimir> interesting

2017-11-23T00:29:09 < BrainDamage> you can ofc only sniff the data that goes trough the local lan
2017-11-23T00:29:16 < BrainDamage> not the internet side
2017-11-23T00:29:28 < BrainDamage> internet side requires actual access to the router
2017-11-23T00:29:49 < kakimir> that is pretty much what I'm interested about
2017-11-23T00:30:05 < kakimir> almost having seperate router would be useful
2017-11-23T00:30:11 < kakimir> instead of modem-router
2017-11-23T00:30:28 < BrainDamage> yeah, it's almost always better to have modem and router separated, just more expensive
2017-11-23T00:31:28 < BrainDamage> i mean, with arp spoofing you can check traffic that goes back and forth to the internet, but only that has source/dest a lan machine
2017-11-23T00:31:32 < BrainDamage> not the router itself
2017-11-23T00:31:59 < BrainDamage> which is typically 99% of the cases you're interested in
2017-11-23T00:32:09 < kakimir> you need to poison every client you want to sniff?
2017-11-23T00:32:31 < kakimir> it's client side method right?
2017-11-23T00:32:50 < kakimir> I'm more currious what my routers are doing
2017-11-23T00:32:52 < BrainDamage> depends which direction of comm you're interested in
2017-11-23T00:33:05 < kakimir> in case of mirai
2017-11-23T00:33:11 < BrainDamage> if you spoof the router, then you can intercept all the traffic that goes to the router
2017-11-23T00:33:20 < Kug3lis> Kakimir no, I am doing DataLogger for sensors and etc and want to be able access sd card contents then its still running
2017-11-23T00:33:26 < BrainDamage> if you spoof a client, then you can check all the traffic that goes to a client
2017-11-23T00:33:41 < BrainDamage> if you want all the traffic from/to a client, then you need the router AND that client
2017-11-23T00:33:42 < kakimir> Kug3lis goes into defence
2017-11-23T00:34:16 < kakimir> let's say I have one router in downstream of modem-router
2017-11-23T00:34:32 < kakimir> and I want to look for mirai and similar
2017-11-23T00:35:19 < BrainDamage> with arp spoofing you'd be only be able to detect mirai infected lan clients
2017-11-23T00:35:24 < BrainDamage> not the router itself
2017-11-23T00:36:06 < kakimir> I need to physically go between the routers
2017-11-23T00:36:19 < BrainDamage> get a scalpel
2017-11-23T00:36:24 < kakimir> have you had mirai BrainDamage ?
2017-11-23T00:36:35 < kakimir> I suspect it in one of my routers
2017-11-23T00:36:46 < kakimir> I was acting weird

2017-11-23T00:36:57 < kakimir> had lan side admin - admin combo
2017-11-23T00:37:03 < BrainDamage> as long as i don't have ridicolously bad perf, who cares
2017-11-23T00:37:07 < kakimir> brother used some nasty vpn service
2017-11-23T00:37:27 < BrainDamage> i treat anything past my network plug as an untrusted machine
2017-11-23T00:37:34 < BrainDamage> that includes my other lan pcs
2017-11-23T00:37:49 < kakimir> but you trust your main machine?
2017-11-23T00:38:11 < BrainDamage> i trust my pc, i trust my other arm boards, i don't trust the lan that links them
2017-11-23T00:38:27 < BrainDamage> or the shitty router
2017-11-23T00:38:37 < kakimir> you know intel is already inside your machine?
2017-11-23T00:38:44 < BrainDamage> yes, and?

2017-11-23T00:39:19 < sync> or rather minix'd
2017-11-23T00:39:42 < kakimir> somebody somewhere has backdoor keys to your machine
2017-11-23T00:39:52 < sync> that will always be the case
2017-11-23T00:40:26 < kakimir> but does it go deeper than that
2017-11-23T00:40:39 < BrainDamage> unless you manage to piss off someone, your main concern is drive by attacks
2017-11-23T00:40:46 < kakimir> hidden parts inside hidden part
2017-11-23T00:40:55 < BrainDamage> so protecting the network exposed surface is what you care
2017-11-23T00:41:01 < BrainDamage> rest is crypto nerd autism
2017-11-23T00:41:10 < jadew> BrainDamage, I treat them the same
2017-11-23T00:41:46 < jadew> I make it so they can be accessed and access only PCs they should be dealing with
2017-11-23T00:42:20 < jadew> in some instances, I don't let them access aything, other than already established connections (initiated by somewhere else)
2017-11-23T00:42:39 < jadew> for example, I have thingie that connects to the TV
2017-11-23T00:42:54 < jadew> that thing can only access the internet

2017-11-23T00:44:01 < BrainDamage> bonus points, my setup in lan or internet changes 0, only an ip/dns
2017-11-23T00:44:49 < BrainDamage> it's slightly more cognitive load to setup to search for the right software, but it's simpler in configuration, literally the same software
2017-11-23T00:44:53 < jadew> well, you have to relax those rules a bit, otherwise you're losing a lot of functionality
2017-11-23T00:45:13 < BrainDamage> such as?
2017-11-23T00:45:21 < jadew> sharing media for example
2017-11-23T00:45:40 < jadew> the media server is open to the lan

2017-11-23T02:25:23 < Laurenceb_> hyperloop is even more lulzy than emdrive tbh
2017-11-23T02:26:40 < Laurenceb_> at least emdrive admits its outside the realm of real physics
2017-11-23T02:26:56 < Laurenceb_> whereas hyperloop just fudges equations until it works
2017-11-23T02:28:26 < Laurenceb_> hyperloop even has magic steam with zero volume

2017-11-23T03:52:18 < upgrdman> jadew, why not just use a hot air station
2017-11-23T03:52:34 < upgrdman> shit, i've use a fucking HEAT GUN before with 0% failure rate
2017-11-23T03:52:55 < jadew> upgrdman, I do that for one offs
2017-11-23T03:53:17 < jadew> but if I make 10 or 20 boards, it seems like a waste of time
2017-11-23T03:53:26 < upgrdman> or if you want to be pro-er, a toaster over. $15.
2017-11-23T03:53:46 < upgrdman> turn temp to max, turn on, when solder melts, turn off and open door.
2017-11-23T03:53:59 < jadew> yeah, I've been looking at that too

2017-11-23T03:55:22 < jadew> branjb, the problem with the hot plate is that it has a lot of thermal mass, so you can't cool it as fast as you can with an oven

2017-11-23T03:56:19 < branjb> yup, got to be a lot more careful. the way i usually do it is put a piece of aluminum between the board and hot plate, then once everything has reflowed, I just very carefully lift the aluminum up

2017-11-23T03:56:47 < jadew> can't you use a pan?

2017-11-23T13:44:16 < jadew> pin 13 is not connected to 14
2017-11-23T13:44:41 < jadew> pin 10 is not connected to R6
2017-11-23T13:45:02 < jadew> (for U2)
2017-11-23T13:45:12 < jadew> U1 pin 15 not connected to gnd
2017-11-23T13:45:28 < karlp> neither of which should matter for talking to the stm32
2017-11-23T13:45:46 < karlp> that u1 pin 15 will though I bet
2017-11-23T13:45:55 < jadew> I don't know what the issue is, I didn't follow
2017-11-23T13:46:01 < jadew> I just thought it's a funny pic, so I clicked
2017-11-23T13:46:10 < jadew> it's just a bit funny
2017-11-23T13:47:22 < tr0ubl3> They are connected on the board the schematic spazzed out
2017-11-23T13:47:30 < karlp> tr0ubl3: can you check continuity from the lead on pin 15 to a different ground point?
2017-11-23T13:47:50 < tr0ubl3> Okay
2017-11-23T13:52:31 < tr0ubl3> Yeah its connected
2017-11-23T13:52:48 < zyp> tr0ubl3, you mentioned a wrong capacitor value
2017-11-23T13:52:49 < zyp> which?
2017-11-23T13:53:05 < tr0ubl3> https://i.imgur.com/uT9JSyh.png is the pcb you can see its stitched to gnd plane

2017-11-23T13:53:34 < tr0ubl3> C5 was not good wasnt giving the correct voltage spike to turn on the bq
2017-11-23T13:53:54 < zyp> and because of that it was getting hot?
2017-11-23T13:54:32 < tr0ubl3> No it was getting hot because of a short between pins 8 and 9 on U2. I am now using a different board which does not have the short, but cannot be flashed
2017-11-23T13:55:06 < zyp> okay, that makes sense
2017-11-23T13:56:08 < zyp> to rule out any power issues, can you measure directly between pins 15 and 16 on the stm that it is getting 3.3V?

2017-11-23T13:57:42 < tr0ubl3> Yeah its getting 3.3
2017-11-23T13:58:05 < zyp> okay, so the chip is powered
2017-11-23T13:58:28 < zyp> how are you hooking up the debugger? got a pic?
2017-11-23T14:02:15 < tr0ubl3> https://i.imgur.com/KyN3LS7.jpg bad angle but here is board connection
2017-11-23T14:02:31 < tr0ubl3> And where those wires go into debugger https://i.imgur.com/TW4G15e.jpg
2017-11-23T14:03:34 < zyp> tried without the blue?
2017-11-23T14:05:00 < tr0ubl3> Yeah nothing. This is fustrating.
2017-11-23T14:06:54 < karlp> you're not connecting to teh swim pin instead of the swdio pin are you?
2017-11-23T14:07:24 < karlp> shouldn't we be able to see a gold pin in front of the white lead? if you were connected to swdio?
2017-11-23T14:07:31 < karlp> or is the angle just wrong and it's behind the shield?
2017-11-23T14:07:48 < karlp> (I've not checked that you've got the right pins for swdio/swdclk on the tsop20 package at all)
2017-11-23T14:08:00 < zyp> I checked that, looks all right to me
2017-11-23T14:08:57 < aandrew> whoa, jadew wins the prize
2017-11-23T14:09:06 < aandrew> I did not notice the missing junctions
2017-11-23T14:09:16 < karlp> aandrew: well, except that they checked that, and the pcb layout shows it connected, sooo
2017-11-23T14:09:44 < tr0ubl3> The swclk and swdio and connected to the right headers :/
2017-11-23T14:09:56 < tr0ubl3> I think its probably to do with the bad reset config maybe?
2017-11-23T14:10:09 < zyp> reset doesn't matter
2017-11-23T14:10:38 < aandrew> tr0ubl3: you had an identical board flash before, so we know the layout is good
2017-11-23T14:10:44 < karlp> unless the spu is inlockups.
2017-11-23T14:10:49 < tr0ubl3> I am stumped then.
2017-11-23T14:10:54 < zyp> aandrew, did he? news to me
2017-11-23T14:10:59 < aandrew> I thought he did?
2017-11-23T14:11:09 < zyp> I haven't been following everything
2017-11-23T14:11:11 < karlp> only thing that's worked is the stlink dongle to a bluepill
2017-11-23T14:11:41 < tr0ubl3> No aandrew is right, I managed to get a previous board flashing
2017-11-23T14:11:53 < aandrew> I would put 100nf from reset to ground and 1k from reset to 3.3V, see if the STM32 is identified by the STLINK. If not, swap SWDIO/SWDCK and try again (I have fucked this up numerous times)
2017-11-23T14:12:06 < zyp> tr0ubl3, what has changed since then?
2017-11-23T14:12:13 < aandrew> this is too simple to be a real issue
2017-11-23T14:12:26 < aandrew> brb rebooting
2017-11-23T14:12:31 < Thorn> does this board even pass DRC
2017-11-23T14:12:36 < tr0ubl3> zyp: I blew that board up so soldered a new one
2017-11-23T14:12:39 < tr0ubl3> Yes
2017-11-23T14:13:09 < zyp> tr0ubl3, solder another, try again
2017-11-23T14:13:11 < Thorn> this is the messiest routing I've seen in a long time
2017-11-23T14:13:29 < zyp> sounds like you killed the mcu during soldering or something
2017-11-23T14:13:35 < tr0ubl3> Yeah I know I have not done this before
2017-11-23T14:14:57 < zyp> if the chip is powered and you have swdio and swclk right, you should get a debugger connection, and if you know the debugger is good, that leaves a dead mcu
2017-11-23T14:16:32 < jadew> yeah, looks like they fixed that in kicad, in the past it wouldn't have connected the two networks
2017-11-23T14:17:00 < aandrew> don't bust his balls too much, he's a newb :-)
2017-11-23T14:17:07 < aandrew> lots of time to teach him good routing practices
2017-11-23T14:17:21 < tr0ubl3> I will solder another board and get back to you guys. Thanks for the help sofar
2017-11-23T14:17:30 < zyp> good luck
2017-11-23T14:17:40 < aandrew> tr0ubl3: don't solder anything but the debug header, the STM32 and the bypass capacitors
2017-11-23T14:18:02 < aandrew> well maybe D1 and R5 as well
2017-11-23T14:18:12 < zyp> unless you're reflowing it, in that case just do it all
2017-11-23T14:18:14 < aandrew> and R4 -- basically the bare minimum needed to test the STM32
2017-11-23T14:18:43 < aandrew> I still can't believe I didn't catch the missing junctions
2017-11-23T14:19:26 < jadew> aandrew, doesn't seem to be an issue in recent kicad versions tho
2017-11-23T14:19:34 < zyp> not too hard to miss, there's more glaring issues in that schematic :)
2017-11-23T14:19:38 < jadew> I got burned by it, so I always add junctions now anyway
2017-11-23T14:20:33 < zyp> jadew, is junctions something you have to manually add?
2017-11-23T14:20:42 < jadew> zyp, in some cases, yeah

2017-11-23T20:46:56 < kakimir> can you set such thing for rtos task there is time window set for it when it needs to perform it's stuff
2017-11-23T20:47:15 < kakimir> or at least begin
2017-11-23T20:47:37 < kakimir> I mean if some sensor data is needed for some process
2017-11-23T20:47:56 < kakimir> "hey check that data during next 10ms"
2017-11-23T20:59:28 < Cracki> that's a "software timer"
2017-11-23T20:59:48 < Cracki> or a task with higher priority
2017-11-23T21:00:13 < Cracki> or look into scheduling with deadlines
2017-11-23T21:01:15 < kakimir> I need to get into RTOS now
2017-11-23T21:01:40 < Cracki> freertos perhaps
2017-11-23T21:01:41 < kakimir> my project is deadstill I have started to write my own management systems
2017-11-23T21:01:46 < Cracki> don't
2017-11-23T21:01:52 < kakimir> chibios they said
2017-11-23T21:01:56 < Cracki> or that
2017-11-23T21:02:04 < Cracki> depends on what facilities you need
2017-11-23T21:02:16 < Cracki> freertos doesn't care about networking
2017-11-23T21:02:28 < Cracki> that's an addon module afaik
2017-11-23T21:02:44 < Cracki> http://www.freertos.org/embeddedtcp.html
2017-11-23T21:06:28 < kakimir> they say chibios is the bestest
2017-11-23T21:06:45 < Cracki> can't compare
2017-11-23T21:06:50 < Cracki> never used it
2017-11-23T21:08:00 < qyx> too much static configuration in chibios
2017-11-23T21:08:06 < qyx> at least in the old versions I used to use
2017-11-23T21:08:12 < qyx> now freertos ftw
2017-11-23T21:08:55 < kakimir> how many days it took to get it going?
2017-11-23T21:09:02 < Cracki> huh? static config? how so?
2017-11-23T21:09:32 < qyx> Cracki: many peripherals couldn't be reconfigured during runtime
2017-11-23T21:09:35 < qyx> also board files
2017-11-23T21:09:40 < Cracki> freertos on avr is trivial. unpack, fight the compiler+linker, write a main() and some tasks
2017-11-23T21:10:12 < Cracki> qyx, ic. how does that look in freertos? haven't had to reconfigure anything through freertos yet, only my own custom code
2017-11-23T21:10:42 < qyx> you just compile an empty main with a copy-pasted freertos config and it works
2017-11-23T21:10:54 < qyx> not empty, you have to start the scheduler at least
2017-11-23T21:11:17 < Cracki> yes yes
2017-11-23T21:11:37 < qyx> if it was possible to use the chibios schedular without the hal, I would have done it
2017-11-23T21:11:43 < qyx> but iirc it was not possible at that time
2017-11-23T21:11:44 < kakimir> I wonder how things work in NXP LPC realm
2017-11-23T21:11:45 < Cracki> wanting to understand your choice of freertos, you mentioned runtime reconfiguration
2017-11-23T21:12:10 < qyx> I just wanted a basic scheduler for a custum hal
2017-11-23T21:12:20 < qyx> freertos does exactly this
2017-11-23T21:12:29 < qyx> maybe chibios too now, idk
2017-11-23T21:12:53 < Cracki> that's how I saw it too
2017-11-23T21:13:03 < fenugrec> chibios can be used without its HAL, no ?

2017-11-23T21:13:23 < qyx> maybe yes, last version I used was some ancient 2.4.x
2017-11-23T21:13:39 < kakimir> DelvingDeeper: check your tool manual
2017-11-23T21:14:59 < kakimir> what you can reconfigure runtime?
2017-11-23T21:15:12 < kakimir> all rtos parameters?
2017-11-23T21:15:15 < DelvingDeeper> kakimir: tool manual?
2017-11-23T21:15:22 < qyx> no, the hal
2017-11-23T21:15:35 < kakimir> DelvingDeeper: some tool is giving you that code
2017-11-23T21:15:37 < qyx> I am referring to a decision made ~2y ago
2017-11-23T21:16:06 < kakimir> qyx: why you need to reconfigure hal at runtime?
2017-11-23T21:16:41 < qyx> because I needed device discovery and such things
2017-11-23T21:16:45 < DelvingDeeper> kakimir: you mean the toolchain?
2017-11-23T21:16:46 < Cracki> ah, I think the chibios license is putting some people off
2017-11-23T21:17:01 < kakimir> DelvingDeeper: whatever outputs the message

2017-11-23T21:18:02 < kakimir> runtime?
2017-11-23T21:18:10 < kakimir> why

2017-11-23T23:10:48 < kakimir> but I don't really care when it happens

2017-11-23T23:17:51 < kakimir> yes I'm at phase of getting grips of EVERYTHING

2017-11-24T00:04:11 < kakimir> what is oh
2017-11-24T00:04:19 < kakimir> interesting trivia
2017-11-24T00:07:16 < kakimir> hah wow
2017-11-24T00:07:29 < kakimir> you can trace rtos tasks with analog output
2017-11-24T00:07:50 < kakimir> each task having it's own level
2017-11-24T00:09:46 < englishman> hungarian notation looks worse than polish notation
2017-11-24T00:13:53 < kakimir> can higher tick variables be used in newer freertos?
2017-11-24T00:13:57 < kakimir> like 32bit?

2017-11-24T00:33:06 < karlp> still faster than MTP?
2017-11-24T00:33:25 < karlp> yeah, I've often fallen back to adb for shit
2017-11-24T00:33:50 < kakimir> totally fastest possible thing
2017-11-24T00:33:52 < karlp> kakimir: re ticks, current freertos can even be in deadline mode "tickless" for lower power
2017-11-24T00:34:02 < kakimir> maybe some wireless transfer might be faster
2017-11-24T00:34:21 < kakimir> how does it work?

2017-11-24T01:16:46 < karlp> yep
2017-11-24T01:16:59 < aandrew> balls
2017-11-24T01:17:10 < karlp> m0 has a MTB thing instead, which you _do_ read out via swd pins
2017-11-24T01:17:12 < aandrew> also, I fucking hate professional documentation that uses the word "learnt"
2017-11-24T01:17:23 < aandrew> MTB? I did not know about this periph

2017-11-24T14:00:50 < zyp> dongs, so you know writes aren't happening, time to check RCC, enable bit is set (or maybe it's not implemented either, that'd make it more obvious)
2017-11-24T14:01:35 < zyp> if RCC enable is properly set, maybe double check register base address
2017-11-24T14:01:54 < tr0ubl3> Interesting I wonder why I couldnt flash it then
2017-11-24T14:02:26 < zyp> but you still have to make the leap from "wtf, can is not turning on" to "oh, can is not present in this chip"
2017-11-24T14:02:30 < dongs> tr0ubl3: what did stlink/jlink debug log say when you tried
2017-11-24T14:02:48 < tr0ubl3> Its just said that it couldnt connect and the voltages were fine
2017-11-24T14:03:14 < zyp> tr0ubl3, you soldered a new board now and it works?
2017-11-24T14:03:44 < tr0ubl3> zyp: I soldered just the components related to the stm32 and its fine, I will try soldering everything else and see if it still works
2017-11-24T14:03:52 < zyp> it should
2017-11-24T14:04:11 < zyp> and yeah, you've either killed the mcu on the previous board or shorted out the swd lines
2017-11-24T14:04:48 < zyp> I don't know how you've killed it either
2017-11-24T14:06:24 < qyx> yes, at first, suspect libopencm3
2017-11-24T14:06:30 < zyp> the only stm32s I've managed to kill have been by powering it wrong, which usually makes it fuse the power supply pins together so it keeps shorting the supply
2017-11-24T14:06:31 < qyx> returns error
2017-11-24T14:06:42 < qyx> meh, check the libopencm3 code

2017-11-24T14:39:11 < aandrew> Laurenceb: back in high school I found a shitload of those biiig blue electrolytic caps with screw terminals. decided to build the biggest, baddest linear power supply I could
2017-11-24T14:39:22 < aandrew> found a transformer that must've weighed 30lbs
2017-11-24T14:39:32 < aandrew> found a couple diode bridges that had big heatsinks on them
2017-11-24T14:39:50 < aandrew> designed a PCB in OrCAD, photo etched it
2017-11-24T14:39:59 < aandrew> I was the king shit in high school tech shop of course
2017-11-24T14:40:23 < aandrew> anyway... got it all wired up, moment of truth... all the other kids were surrounding my bench to see Exclaibur power up
2017-11-24T14:40:32 < aandrew> I reach across the bench to plug it in
2017-11-24T14:40:35 < aandrew> KA-FUCKING-BOOM
2017-11-24T14:41:05 < aandrew> one of the 78xx regulators was cracked in half like your F4
2017-11-24T14:41:20 < aandrew> one of the diode bridges was just gone - four legs sticking up out of the board only
2017-11-24T14:41:37 < aandrew> after the smoke cleared and I changed my underwear, the teacher sat us all down and taught a lesson on inrush current
2017-11-24T14:41:57 < aandrew> fucking asshole, he knew what was gonna happen the moment he saw me lug that transformer out of the scrap heap
2017-11-24T14:42:24 < aandrew> all those capacitors with a transformer that I'm sure had a surge current rating of at least 100A
2017-11-24T14:42:29 < aandrew> my thick copper traces and heavy wire
2017-11-24T14:42:35 < aandrew> fucking Mr. Jaunzemis. I will never forget him
2017-11-24T14:45:45 < karlp> aandrew: but what is it? just having a higher swdclk? what makes it get a special name?
2017-11-24T14:45:57 < zyp> qyx, I think it's a property of the buses
2017-11-24T14:46:29 < zyp> IIRC accessing invalid addrs on the AHB will signal a fault
2017-11-24T14:46:30 < karlp> aandrew: also, no hate on MTB, just would rather than swo and work on m3+ devices instead
2017-11-24T14:47:06 < zyp> but I'm not sure the APBs have any way of signalling an invalid addr, so invalid addrs in the APB spaces will return 0 instead
2017-11-24T14:47:49 < zyp> IIRC LM4F have GPIO blocks mapped both on APB and AHB
2017-11-24T14:48:01 < PaulFertser> aandrew: wonderful story, thank you. What was the planned output current for that thing, how many 78xx did you have in parallel?
2017-11-24T14:48:05 < zyp> the AHB addrs will fault if block accessed is not powered, the APB addrs won't
2017-11-24T14:49:04 < zyp> aandrew, haha
2017-11-24T14:50:00 < zyp> I also have some capacitor stories from high school
2017-11-24T14:50:27 < zyp> I remember we had a bunch of those in the same size as a D battery
2017-11-24T14:51:43 < zyp> so we soldered a few cm leads to the terminals, charged them and went throwing them to each other, trying not to short the leads while catching it
2017-11-24T14:54:36 < zyp> I think we got stopped by a teacher before anybody managed to hurt themselves
2017-11-24T14:55:31 < aandrew> PaulFertser: I seem to remember I had an external pass transistor board ready (few 2N3055s in parallel type of thing) to offload the heavy lifting of the 78xx but I don't think I'd even had it etched yet. this was just the inaugual power up :-)
2017-11-24T14:56:17 < aandrew> planned output current? I was a smart-ass 15 or 16yo. I hadn't done any real engineering on it, I just saw MASSIVE TRANSFORMER and ZOMG A DOZEN SUPER BIG CAPS and decided I was not building a weenie power supply like everyone else
2017-11-24T14:56:52 < aandrew> I am looking at the RTT implementation source... this actually looks way nicer than SWO
2017-11-24T14:57:16 < aandrew> a lot more flexible and usable on what looks to be all Cortex cores
2017-11-24T14:57:32 < zyp> RTT is a pair of ringbuffers, right?
2017-11-24T14:57:38 < aandrew> zyp: yeah
2017-11-24T14:57:43 < PaulFertser> btw, there's an out of tree patch for openocd that adds RTT with all jtag adapters, not just jlink.
2017-11-24T14:58:21 < aandrew> PaulFertser: very nice. I don't like being beholden to jlink, but I have to admit the hardware just works
2017-11-24T14:58:35 < aandrew> I have no end of trouble with stlink etc, especially when debugging
2017-11-24T14:58:50 < aandrew> jlink, whether though their own closed sw or with openocd, is very stable
2017-11-24T14:59:10 < aandrew> BMP is on my list of "to play with" at some point, just -ENOTIME
2017-11-24T14:59:44 < Steffanx> Better /quit :P
2017-11-24T14:59:58 < aandrew> so MTB is a hardware-assisted branch logger on M0/M0+ only
2017-11-24T15:02:10 < aandrew> ITM has a dedicated pin and emits software trace (what everyone redirects stdout to), hardware trace packets which I'm guessing would be similar to branch logging like MTB, and timestamps
2017-11-24T15:03:13 < aandrew> and then if you have the pins, TIPU is an actual instruction trace output
2017-11-24T15:03:15 < aandrew> is that about right?
2017-11-24T15:03:16 < karlp> there's ITM in m0 too,
2017-11-24T15:03:18 < zyp> which is better is a question of purpose
2017-11-24T15:03:26 < karlp> because that's the peripheral that does some of this stuff internally,
2017-11-24T15:03:42 < aandrew> karlp: hm
2017-11-24T15:03:42 < zyp> do you want transparent tracing or an intrusive facility?
2017-11-24T15:04:37 < aandrew> zyp: right, ITM doesn't take up SRAM for the buffers basically
2017-11-24T15:05:13 < karlp> I think you need a s/TPIU/ETM/ but yeah,
2017-11-24T15:05:31 < karlp> itm can do lots more than just getting printf redirected to it too.
2017-11-24T15:05:43 < aandrew> karlp: I thought MTB was just the branch trace from ITM basically. take ITM, strip out the packetizer and output pin, strip out sw trace and timestamps and you have MTB is what I thought
2017-11-24T15:06:03 * karlp shrugs
2017-11-24T15:06:17 < karlp> the block diagrams are complicated and have lots of back and forth interconnections
2017-11-24T15:06:29 < aandrew> karlp: right, ITM has packetizer and otuput pin, and can do sw trace (what everyone redirects to), but also branch logging and timestamping
2017-11-24T15:06:34 < karlp> dwt/itm/tpiu/etm/mtb/swo
2017-11-24T15:06:54 < karlp> yeah, some of the timestamping and branching stuff is from the dwt part of coresight,
2017-11-24T15:07:02 < karlp> but it's just names.
2017-11-24T15:07:06 < aandrew> looking at arm docs, it *sounds* like TIPU is an ehanced (parallel, faster) output module for ITM/ETM
2017-11-24T15:07:25 < karlp> yeah, but you can have tpiu formatting on or off too.
2017-11-24T15:07:44 < karlp> I think tpiu is only really interesting for socs with multiple cores or multiple coresight compat devices on it
2017-11-24T15:07:54 < karlp> so you can have them have their trace port id on it for tpiu to multiplex
2017-11-24T15:08:03 < aandrew> right
2017-11-24T15:08:04 < karlp> for single core cortex-m stuff, I don't thik tpiu does anythign useful
2017-11-24T15:08:16 < zyp> how about high res traces?
2017-11-24T15:08:27 < karlp> you use etm for that isn't it?
2017-11-24T15:08:41 < karlp> and iirc, that can _also_ have tpiu formatting or not.
2017-11-24T15:08:52 < zyp> haha, well
2017-11-24T15:08:58 < zyp> I have no idea what is what either :)
2017-11-24T15:09:26 < karlp> suffice to say, you can get a shitload of data out, and most of the tools don't do a great job of helping use it all.
2017-11-24T15:10:05 < zyp> I figure pro tools does, but they are $$$$
2017-11-24T15:10:28 < PaulFertser> aandrew: in armv7-m there're various modules that can provide additional debugging information, ITM, DWT, ETM. All of them are connected to TPIU and then you configure TPIU to output that information somehow. E.g. via single SWO pin.
2017-11-24T15:10:50 < aandrew> right, I just found this diagram: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0439b/BIIFFGJD.html
2017-11-24T15:11:13 < PaulFertser> aandrew: if you're using just ITM, there's no need to enable TPIU formatter, but if you add ETM, you'll have to enable it.
2017-11-24T15:11:32 < karlp> aandrew: what section are you looking at? thats just a link to the entire TRM
2017-11-24T15:11:38 < aandrew> oh sorry

2017-11-24T15:12:50 < zyp> that makes sense
2017-11-24T15:13:25 < aandrew> http://infocenter.arm.com/help/topic/com.arm.doc.ddi0440c/CHDCBDEB.html is good too
2017-11-24T15:13:40 < zyp> so TPIU is the trace IO block, ETM does hw trace, ITM does sw trace
2017-11-24T15:13:43 < dongs> why arm doc urls so fuckin ggross
2017-11-24T15:13:46 < dongs> and why are they using frames
2017-11-24T15:13:46 < dongs> in 2017
2017-11-24T15:13:47 < dongs> fuck
2017-11-24T15:13:48 < aandrew> indicates that like PaulFertser said, anything you want out of ETM must go through TIPU
2017-11-24T15:14:22 < PaulFertser> aandrew: if you need it out, yes, but on some SoCs you can have ETM saving data to a memory buffer instead. And then retrieve it somehow.
2017-11-24T15:14:39 < aandrew> right, through some interface hanging off ATB I suppose
2017-11-24T15:15:14 < PaulFertser> Often you do it on the target itself, as it's running a fully-functional OS.
2017-11-24T15:15:17 < dongs> interface hanging off AKB48
2017-11-24T15:16:09 < PaulFertser> zyp: no, ITM is not related to tracing. ITM works to output arbitrary multi-channel data from user application.
2017-11-24T15:16:28 < karlp> dwt is also connected to itm
2017-11-24T15:16:41 < zyp> PaulFertser, that's what I meant
2017-11-24T15:16:46 < PaulFertser> zyp: ok, sorry
2017-11-24T15:17:00 < zyp> I'd call them software-triggered trace events
2017-11-24T15:17:23 < PaulFertser> karlp: I wonder why nobody has so far contributed dwt configuration code to openocd.
2017-11-24T15:17:30 -!- Rob235 [~Rob235@pool-100-35-64-150.nwrknj.fios.verizon.net] has joined ##stm32
2017-11-24T15:18:08 < karlp> because it can all be done in tcl
2017-11-24T15:18:12 < aandrew> so ITM is strictly "here is a low-impact way of getting data in and out of your application" where low-impact means it doesn't disturb your usual peripherals
2017-11-24T15:18:39 < aandrew> er ITM is out only
2017-11-24T15:18:40 < karlp> and only out, no in.
2017-11-24T15:18:56 < zyp> I see it as useful to interleave software events with a hardware trace
2017-11-24T15:19:20 < karlp> you can get exception tracing from DWT output via ITM to swo, it's pretty neat,
2017-11-24T15:19:36 < zyp> easier than to correlate a UART log to a hardware trace
2017-11-24T15:19:37 < karlp> and if you're putting data on itm channels, instead of damn printffing to it, you can get a lot more data output
2017-11-24T15:19:39 < aandrew> so if your debug interface supports memory reads that don't disturb the core, RTT gives you a really nice bidirectional side channel
2017-11-24T15:19:55 < karlp> and that's a property of coresight, not hte debug interface.
2017-11-24T15:20:01 < karlp> jlink isn't special there.
2017-11-24T15:20:17 < karlp> stlink can do it too. so can cmsis-dap for instance
2017-11-24T15:20:23 < aandrew> right, I know it's not anything jlink specific. it's just a matter of wiggling the SWD pins in a way that pleases the controller
2017-11-24T15:20:42 -!- tavish [~tavish@unaffiliated/tavish] has quit [Quit: Leaving]
2017-11-24T15:20:56 < karlp> yeah rtt gives you a "standard" memory interface to outside, taht in most cases is faster than stuff like semihosting
2017-11-24T15:21:06 < PaulFertser> lol, someone translated full openocd 0.7.0 manual to russian.
2017-11-24T15:21:07 < karlp> but you need to include the code for rtt into your app, and reserve teh ram
2017-11-24T15:21:16 < karlp> 0.7? why?!
2017-11-24T15:21:32 < aandrew> karlp: right, RTT consumes RAM and needs a sw library in your code
2017-11-24T15:22:13 < aandrew> and yes, ITM is usually used for printf() output but if you want to be pro you use it for far more interesting and detailed things
2017-11-24T15:22:19 < PaulFertser> karlp: no idea, http://microsin.net/programming/ARM/openocd-manual-part1.html
2017-11-24T15:22:22 < aandrew> I have to read up on SWO
2017-11-24T15:22:37 < aandrew> and how to get other info out of it
2017-11-24T15:22:57 < jpa-> ITM/SWO is also much faster if you use it for unformatted values instead of printf text
2017-11-24T15:23:06 < aandrew> yes
2017-11-24T15:23:13 < aandrew> vsprintf() is a pig
2017-11-24T15:23:23 < dongs> maybe if you use GNU
2017-11-24T15:23:25 < PaulFertser> karlp: probably because so many russians just can't be bothered to learn english :/
2017-11-24T15:23:27 < dongs> did you know?
2017-11-24T15:23:33 < dongs> entire keil libc
2017-11-24T15:23:40 < dongs> is smalelr than pulling in printf() from newlib
2017-11-24T15:23:42 < dongs> entire
2017-11-24T15:23:49 < dongs> thats how much of a joke newlib/gcc shit is
2017-11-24T15:24:05 < dongs> *and* it doesnt need garbage like _sbark and wahtever other shit that happens if you try to use anything normal
2017-11-24T15:24:05 < aandrew> haha really? that's awesome
2017-11-24T15:24:49 < Laurenceb> >using printf
2017-11-24T15:24:57 < dongs> Laurenceb: not a problem with keil!

2017-11-24T15:24:58 < Laurenceb> >not using rfprintf
2017-11-24T15:25:14 < dongs> also, my opensores flight shit used some faggot printf() if building with gcc
2017-11-24T15:25:19 < dongs> which was buggy and didnt support float etc
2017-11-24T15:25:25 < Laurenceb> epin fail
2017-11-24T15:25:28 < dongs> keil printf WITH float support was SMALELR than that rfprintf shit built
2017-11-24T15:25:30 < PaulFertser> dongs: so how big is entire keil libc actually, in bytes?
2017-11-24T15:25:56 < dongs> PaulFertser: orders of magnitude smaller than newlib
2017-11-24T15:28:01 < Steffanx> ^ aka: i dont know
2017-11-24T15:28:08 < dongs> no, more like i dont give a shit
2017-11-24T15:28:25 < Steffanx> Also: i dont know, never looked into it.
2017-11-24T15:28:40 < dongs> if gnu libc didnt fucking suck, why would people waste time writing "fast" printfs?
2017-11-24T15:28:54 < zyp> "i dont give a shit about making substantiated claims, I just wanna throw shit"
2017-11-24T15:29:01 < dongs> of course, zyp
2017-11-24T15:29:07 < zyp> :)
2017-11-24T15:29:07 < dongs> that is the definition of trolling, after all
2017-11-24T15:29:08 < Steffanx> Zyp understands it.

2017-11-24T15:31:45 < dongs> or whatever gross c++ equivalent of this shit is
2017-11-24T15:31:51 < jpa-> nowadays everyone should just use println!()
2017-11-24T15:32:00 < dongs> from arduino?
2017-11-24T15:32:03 < jpa-> no, rust
2017-11-24T15:32:11 < dongs> is ! significnat?
2017-11-24T15:32:14 < jpa-> yes
2017-11-24T15:32:15 < dongs> significant
2017-11-24T15:32:19 < dongs> what the fuck does it mean
2017-11-24T15:32:22 < jpa-> it's a macro
2017-11-24T15:33:43 < dongs> i probably dont want to know.
2017-11-24T15:34:03 < zyp> I don't either
2017-11-24T15:34:25 < jpa-> https://doc.rust-lang.org/src/std/macros.rs.html#150-154 that's how it looks in source code - beautiful, right?
2017-11-24T15:34:46 < zyp> haha
2017-11-24T15:34:50 < dongs> fuck!rust!
2017-11-24T15:34:59 < qyx> worse than c++ templates
2017-11-24T15:35:06 < dongs> Serial.print("LE "); if (Error52<0x10) {Serial.print("0");} Serial.print(Error52, HEX); if (Error53<0x10) {Serial.print("0");} Serial.println(Error53, HEX);
2017-11-24T15:35:11 < dongs> this is the kinda shit I have to deal with
2017-11-24T15:35:27 < jpa-> https://doc.rust-lang.org/src/std/macros.rs.html#328-330 they hid the code!
2017-11-24T15:35:28 < dongs> because faggotduino doesnt have printf() or whatever with formatting
2017-11-24T15:36:07 < dongs> and yes, this is all on one line
2017-11-24T15:36:08 < zyp> jpa-, shit that language looks messy
2017-11-24T15:36:29 < dongs> who came up with that rust shit
2017-11-24T15:36:39 < dongs> shit looks like someting o6 would love
2017-11-24T15:36:41 < jpa-> zyp: yeah, it does, atleast at first - quite a bit of new syntax
2017-11-24T15:37:06 < jpa-> it does have some nice features for detecting bugs at compile time but seems a bit difficult to get stuff to compile :P
2017-11-24T15:38:06 < jpa-> dongs: mozilla :P
2017-11-24T15:38:22 < Laurenceb> https://github.com/Laurenceb/Equine/blob/master/Util/rprintf.c
2017-11-24T15:38:58 < karlp> yeah, recommending a gpl printf. -> fuck off
2017-11-24T15:39:33 < zyp> haha
2017-11-24T15:39:39 < jpa-> but i wouldn't be surprised if rust gains some significant following in the mcu world also in the next decade or so
2017-11-24T15:39:40 < PaulFertser> zyp: it has compile-time object lifetime tracking, unlike C++.
2017-11-24T15:39:59 < dongs> jpa, good fucking luck
2017-11-24T15:40:02 < zyp> PaulFertser, compile time?
2017-11-24T15:40:07 < jpa-> PaulFertser: be careful saying that, someone will show you 5000 line C++ template that does the same
2017-11-24T15:40:34 < jpa-> zyp: like RAII, but stricter rules that make it impossible to have stuff like dangling references
2017-11-24T15:40:43 < PaulFertser> zyp: yes, you annotate objects and pass them around and compiler checks that you are not doing the wrong thing regarding lifetime.
2017-11-24T15:40:55 < zyp> jpa-, so RAII with smartpointers
2017-11-24T15:41:04 < karlp> then someone throws unsafe all over it and it falls back in a heap right?
2017-11-24T15:41:04 < dongs> how fucking lazy/shit is your code if you can't see these kinda problems in it automatically
2017-11-24T15:41:07 < dongs> while writing it
2017-11-24T15:41:13 < jpa-> (also make it very annoying to do things like function_that_modifies_two_things(&myarray[0], &myarray[1]) }
2017-11-24T15:41:16 < karlp> so, like, all the periperhal access code for micros in rust?
2017-11-24T15:41:43 < jpa-> zyp: no, RAII with compile-time resolving of lifetimes; it also has smart pointers though
2017-11-24T15:42:20 < jpa-> karlp: yeah, the current peripheral access code is a bit annoying, but it would make sense to have them atleast limit the unsafe{} to the peripheral memory area if nothing else
2017-11-24T15:43:24 < zyp> jpa-, what's the difference?
2017-11-24T15:43:53 < PaulFertser> https://blogs.msdn.microsoft.com/vcblog/2016/03/31/c-core-guidelines-checkers-preview-of-the-lifetime-safety-checker/
2017-11-24T15:44:07 < dongs> zyp, i guess to not be able to walk around your own program pointers/memory
2017-11-24T15:44:13 < jpa-> zyp: the compiler is smarter, and has syntax for stuff like "this function takes ownership of this value"; then problems can be pointed out at compile time
2017-11-24T15:44:21 < dongs> oh that
2017-11-24T15:44:24 < dongs> shruggin
2017-11-24T15:44:36 < zyp> jpa-, so does C++ if you use unique_ptr
2017-11-24T15:44:47 < dongs> is rust interpreted shit
2017-11-24T15:44:49 < jpa-> zyp: putting everything on the heap and using smart pointers for everything might get part of the benefits, though then your problem would be "why won't my stuff get deleted when i expect it to"
2017-11-24T15:44:53 < dongs> or did someone actualyl waste time to make a compiler for it
2017-11-24T15:45:38 < PaulFertser> zyp: lifetime checker has no runtime overhead, compared to a smartpointer. And requires no heap I guess?
2017-11-24T15:45:39 < jpa-> zyp: yep, C++ does some of the same things, but you can e.g. give reference to stack variable to function and automatically check it doesn't leave a dangling reference in C++
2017-11-24T15:45:44 < zyp> jpa-, how can you pass around ownership of something that's not on the heap?
2017-11-24T15:46:03 < zyp> PaulFertser, std::unique_ptr is also compile time checking
2017-11-24T15:46:33 < PaulFertser> zyp: yes, but it's unique access, you either move it somewhere or not.
2017-11-24T15:46:37 < jpa-> zyp: it's all done in compile time using static analysis; whether it is on stack or heap doesn't matter to the memory chip, ownership mainly means who calls destructor etc.
2017-11-24T15:47:03 < zyp> PaulFertser, it's not unique access, it's unique ownership
2017-11-24T15:47:04 < jpa-> dongs: it is compiled, uses llvm
2017-11-24T15:48:34 < zyp> jpa-, so what you're saying is that caller can allocate an object on stack, give it to callee, and callee calls destructor?
2017-11-24T15:48:35 < PaulFertser> zyp: yes, so you either have unique ownership for free or multiple ownership with smartpointer overhead. Rust kinda gives you both if you can make static lifetime checker happy.
2017-11-24T15:48:59 < jpa-> zyp: yes
2017-11-24T15:49:14 < zyp> that sounds weird and pointless
2017-11-24T15:49:39 < jpa-> it separates the concern of managing ownership from the place where the stuff is allocated
2017-11-24T15:50:08 < jpa-> but yeah, in that specific case quite pointless
2017-11-24T15:50:26 < jpa-> i'm not rust-guru enough yet to figure out very good examples, i barely understand it myself
2017-11-24T15:50:46 < jpa-> https://jpa.kapsi.fi/stuff/other/parser.rs match() seems fun though :P
2017-11-24T15:51:26 < zyp> match? looks like a switch to me
2017-11-24T15:51:39 < jpa-> yeah, it is a fancier switch
2017-11-24T15:51:39 < aandrew> hm, I don't see anyh documentation on MTB in the infocenter
2017-11-24T15:52:15 < dongs> im lookin at imgui
2017-11-24T15:52:21 < dongs> to do some simple ui stuff in a windows app
2017-11-24T15:52:35 < aandrew> this is the very first time I've looked at rust code
2017-11-24T15:52:44 < dongs> hopefully the last, too
2017-11-24T15:52:53 < zyp> jpa-, okay, the bit matching stuff looks a bit cute
2017-11-24T15:53:03 < zyp> kinda reminds me of prolog
2017-11-24T15:53:18 < aandrew> heh I haven't played with prolog since I was like 13
2017-11-24T15:53:20 < zyp> which I pretty much remember nothing off
2017-11-24T15:53:36 < aandrew> M23 docs show MTB
2017-11-24T15:53:46 < zyp> programming course in uni included a part on prolog, don't remember much from it
2017-11-24T15:54:12 < jpa-> so far many things about rust feel like they're done right and well, and i do believe the claims of better detecting problems at compile time which is always nice - but not sure if it is still too cumbersome to actually use
2017-11-24T15:54:13 < aandrew> the only reason I was playing with prolog was because dad had a book on AI with prolog and I thought it would let me write super elite AIs
2017-11-24T15:54:19 < aandrew> nothing of the sort happened, I was disappoint
2017-11-24T15:54:44 < PaulFertser> I tried showing my students some prolog (had to learn it a bit for that myself :) ) but they weren't facinated by those multi-way "functions".
2017-11-24T15:55:32 < jpa-> https://jpa.kapsi.fi/stuff/other/heuristics.rs hmm that last line there, i can't understand it anymore :D
2017-11-24T15:55:57 < zyp> I remember I tried to make a sudoku solver in prolog
2017-11-24T15:56:17 < zyp> IIRC it worked, but ended up being way too slow to be useful for anything
2017-11-24T15:56:53 < dongs> .max_by(|&(_,a), &(_,b)| a.partial_cmp(&b).unwrap()).unwrap_or((0,0.0)).0 fucking really?
2017-11-24T15:57:21 < zyp> no wonder dongs hates python, if this is how unfamiliar languages looks :p
2017-11-24T15:57:26 < PaulFertser> btw, is anyone using https://github.com/nholthaus/units (or similar) with microcontrollers here?
2017-11-24T15:59:37 < jpa-> looks like the earlier lambda generates tuples of (index,score) and then the max_by() sorts them by score and .0 takes the index; and then there is this .unwrap() stuff that happens everywhere in rust code :P
2017-11-24T16:00:10 < dongs> zyp, thre's a differenfce between writing readable code, and just writing shit
2017-11-24T16:00:15 < dongs> i.e. python, rust, etc.
2017-11-24T16:00:23 < dongs> im sure the crap above can be broken up into several lines
2017-11-24T16:00:29 < dongs> with descriptive varible names and shit
2017-11-24T16:00:35 < dongs> so that looking at the code a mont hlater still makes sense
2017-11-24T16:00:44 < aandrew> yeah that line reminds me of perl golf contests
2017-11-24T16:00:47 < dongs> but nah, just bunch that shit up all in one line is totally A-OK for newfag coders
2017-11-24T16:00:49 < zyp> PaulFertser, I guess it would work fine, but it looks like it defaults to using doubles, which you might not want
2017-11-24T16:03:20 < PaulFertser> zyp: yes, but this library seems useful even without any conversions, just to make compile-time dimensional analysis, so seems safe to redefine as int.
2017-11-24T16:07:19 < PaulFertser> There's https://github.com/johnmcfarlane/cnl for those who loves fixed point math.
2017-11-24T16:07:49 < dongs> uses cmake, page closed
2017-11-24T16:08:02 < dongs> pretty obvious author doesnt acutally want anyone to use thier shit
2017-11-24T16:08:10 < dongs> amirite y/y/y
2017-11-24T16:08:20 < zyp> to build tests, it says
2017-11-24T16:08:30 < dongs> i didnt care taht much
2017-11-24T16:08:35 < dongs> i see CMakefiles.txt = fuck off
2017-11-24T16:09:01 < zyp> it's header only, so to use it, just include the .h
2017-11-24T16:09:43 < zyp> PaulFertser, what are you gonna use it for? STL has some time unit stuff that looks nice
2017-11-24T16:10:26 < PaulFertser> zyp: I mean for embedded apps where you work with different real world values and do not want to accidentally mess up the order of function arguments or km/mi etc.
2017-11-24T16:10:45 < zyp> makes sense
2017-11-24T16:11:05 < zyp> http://en.cppreference.com/w/cpp/header/chrono <- I was thinking about this stuff
2017-11-24T16:13:04 < PaulFertser> Hm, more on the topic https://github.com/foonathan/type_safe
2017-11-24T16:17:17 < PaulFertser> I've actually spent more time than I expected when I needed to learn/use chrono stuff.
2017-11-24T16:17:41 < karlp> aandrew: yeah, m23 is the new m0, m33 is new m3 isn't it?
2017-11-24T16:17:42 < zyp> okay, I haven't used it yet, just looked at it

2017-11-24T16:18:16 < PaulFertser> You should have no problems, it's just I have too little experience with C++.
2017-11-24T16:18:24 < zyp> but it seems neat, the integer tick stuff should fit embedded well
2017-11-24T16:21:08 < PaulFertser> Not sure why but I never had fun using C++; while shitty eLisp somehow was really enjoyable.
2017-11-24T16:25:18 < tr0ubl3> Before I make it into a PCB I think I made the changes you guys suggested https://i.imgur.com/iiwUxcf.png did I miss anything
2017-11-24T16:26:40 < karlp> yeah, sharing a new schematic?
2017-11-24T16:27:26 < karlp> you should either have a cap to ground on nrst (believe ST) or a resistor to vcc (believe aandrew)
2017-11-24T16:27:43 < dongs> no cap
2017-11-24T16:27:43 < karlp> what ws it in the end? you replaced the part and it worked straight away?
2017-11-24T16:27:48 < dongs> resistor only if you're in noisy environment
2017-11-24T16:27:57 < karlp> dude, go read what st says again.
2017-11-24T16:28:02 < karlp> it says "nothing, cap if you're concerned"
2017-11-24T16:28:09 -!- BrainDamage [~BrainDama@unaffiliated/braindamage] has joined ##stm32
2017-11-24T16:28:11 < tr0ubl3> Yeah it was fine when I replaced it
2017-11-24T16:28:23 < dongs> thats retarded, because the only concern would be a weak 50kish internal pullup
2017-11-24T16:28:28 < dongs> how would a cap help that
2017-11-24T16:28:32 < PaulFertser> Isn't ST datasheet basically saying cap only if you use a button?
2017-11-24T16:28:37 < karlp> PaulFertser: maybe,
2017-11-24T16:28:45 < karlp> eitherway, no need for a pullup

2017-11-24T16:30:02 < tr0ubl3> Okay I am going to try and route the PCB nicely this time
2017-11-24T16:30:16 < PaulFertser> Yeah, what dongs says, if you think internal ~50k pullup might be not enough given the noise expectations, probably worth making it stronger.
2017-11-24T16:32:29 < tr0ubl3> Okay I will add 0.1uF on the nrst line
2017-11-24T16:32:40 < dongs> theres no need for it
2017-11-24T16:32:55 < PaulFertser> We're sometimes using an ad-hoc device made from an automotive spark plug, coil and a trivial generator. Not sure how useful it is, but keyboards and mice stop working when it's turned on. stm32 boards do not.
2017-11-24T16:34:19 < zyp> haha
2017-11-24T16:36:06 < tr0ubl3> okay
2017-11-24T16:40:40 < tr0ubl3> If I could learn any PCB software which would you recommend
2017-11-24T16:41:05 < zyp> any? altium designer
2017-11-24T16:41:16 < dongs> def not kikecad
2017-11-24T16:41:21 < dongs> unless you wanna learn how to code at the same time
2017-11-24T16:41:25 < tr0ubl3> I
2017-11-24T16:41:37 < tr0ubl3> am reasonable at coding haha but altium looks good
2017-11-24T16:41:45 < karlp> yeah, altium isn't going to happen for the only hw person at a software company
2017-11-24T16:41:47 < dongs> i'd say use circuitmaker BUT
2017-11-24T16:41:50 < karlp> sure not legally anyway
2017-11-24T16:41:51 < Steffanx> Diptrace it is then. If your budget is low
2017-11-24T16:41:54 < tr0ubl3> I may have to "obtain" that..
2017-11-24T16:41:55 < zyp> karlp, pff, worked for me
2017-11-24T16:42:02 < dongs> it has no upgrade path to altium
2017-11-24T16:42:09 < dongs> tr0ubl3: are you a student
2017-11-24T16:42:17 < dongs> altidumb student license is liek $100
2017-11-24T16:42:25 < dongs> or 100eur or whatever the shit
2017-11-24T16:42:29 < Steffanx> You cant use that license commercially afaik
2017-11-24T16:42:36 < dongs> his schematic doenst look commercial
2017-11-24T16:42:40 < tr0ubl3> Not at the moment I am taking a year out before university
2017-11-24T16:42:43 < tr0ubl3> Lol
2017-11-24T16:42:50 < Steffanx> If you use that you can as well use a warezed one
2017-11-24T16:42:59 < zyp> what Steffanx said
2017-11-24T16:43:10 < zyp> no point in a legal license if you're going to use it illegally
2017-11-24T16:43:12 * dongs looks at aandrew
2017-11-24T16:43:20 < Steffanx> Yes, aandrew :P
2017-11-24T16:43:40 < dongs> i bought fallout4 the other day cuz it was on sale, but im never gonna install it
2017-11-24T16:43:44 < dongs> cuz pir8 version is less annoying to use
2017-11-24T16:43:54 < dongs> i can just copy entire folder and run it
2017-11-24T16:43:56 < tr0ubl3> Yeah fair enough
2017-11-24T16:43:58 < dongs> no need for steam/drm/faggotry
2017-11-24T16:44:04 < tr0ubl3> I hate games that have the dumb denuvo
2017-11-24T16:44:07 < Steffanx> A college card and or email address is enough for a $99 version i believe
2017-11-24T16:44:38 < tr0ubl3> I have left my school and am going to university next year so idk if I could spin that
2017-11-24T16:45:11 < fenugrec> cadsoft eagle used to have a free version
2017-11-24T16:45:16 < dongs> snort.
2017-11-24T16:45:33 < dongs> now thats a reccomendation i didnt think i'd see in here
2017-11-24T16:45:46 < dongs> good thing they don't have a MAKE:R version anymore, cuz it might as well just be dead anyway
2017-11-24T16:46:08 < Ultrasauce> cad is for suckers, just draw on copper clad with an etch resist marker
2017-11-24T16:46:08 < tr0ubl3> okay I am going to get that dling on my seedbox
2017-11-24T16:46:19 < Steffanx> :P
2017-11-24T16:47:33 < BrainDamage> .. i have actually done that a few times
2017-11-24T16:47:35 < fenugrec> well last I checked (v5 ? 6 ? ) eagle worked just fine wihout taking up 29348723 GB on disk
2017-11-24T16:48:31 < Steffanx> My disk isnt even that large.
2017-11-24T16:48:43 < PaulFertser> How's your printer Steffanx, did mirror help?
2017-11-24T16:48:52 < tr0ubl3> Its a bit annoying that no one else does hw at my company because there is no one to help me
2017-11-24T16:49:12 < tr0ubl3> Well there is another intern but they took 3 months to turn a stepper motor with an arduino so that doesnt count
2017-11-24T16:49:59 < Steffanx> It did help, still have issues with the underextruded first layer PaulFertser
2017-11-24T16:50:17 < Steffanx> PaulFertser: cant do perfectly flat filled first layers
2017-11-24T16:50:45 < Steffanx> It always has gaps.
2017-11-24T16:50:48 < PaulFertser> Steffanx: do you specify custom extrusion width for it? And is skirt looking good and uniform?
2017-11-24T16:50:59 < karlp> fenugrec: free eagle can't be used commercially either, and non-free isn't very cheap these days.
2017-11-24T16:51:14 < fenugrec> true
2017-11-24T16:51:17 < Steffanx> It looks good to me PaulFertser. My printer even auto-levels now :P
2017-11-24T16:51:28 * karlp is just learning kicad,
2017-11-24T16:52:08 < tr0ubl3> I didnt mind kicad but they way you had to do things was quite long and the rendering was irritating
2017-11-24T16:52:14 < Steffanx> PaulFertser: today at work i read it might be an issue with the z-axis and bolts being fastened to tight. Have to look into that
2017-11-24T16:52:22 < Steffanx> Too*
2017-11-24T16:52:35 < PaulFertser> Steffanx: don't you have elastic couplers for the z axis?
2017-11-24T16:52:55 < fenugrec> karlp : how can you tolerate kicad's lack of back annotation
2017-11-24T16:54:02 < englishman> dongs, $16 to renew worksonmymachine.pro, worth it?
2017-11-24T16:54:49 < Steffanx> PaulFertser, never heard of that before, but it seems it does have those
2017-11-24T16:54:49 < dongs> please
2017-11-24T16:54:50 < dongs> i use it
2017-11-24T16:55:16 < karlp> fenugrec: I only use forward annotation, but yes, it's tedious enough to keep doing save net, load net.
2017-11-24T16:55:22 < ReadErr> yo dawgs
2017-11-24T16:55:24 < karlp> though kicad says you can go backwards too,
2017-11-24T16:55:26 < ReadErr> OVH sale
2017-11-24T16:55:29 < ReadErr> if u bout it
2017-11-24T16:55:30 < PaulFertser> Steffanx: https://3dprint.wiki/reprap/anet/a8/coupler
2017-11-24T16:55:34 < dongs> just like readstoner never paid me for gnaa.us

2017-11-24T16:55:55 < ReadErr> dongs: im not gnaa
2017-11-24T16:56:10 < ReadErr> i gave meep your email, hit him up on efnet tho meepsheep
2017-11-24T16:56:12 < karlp> fenugrec: also, i've not even finished my first kicad project to manufacturing yet, so... *shrugs*
2017-11-24T16:56:15 < ReadErr> he prolly forgot
2017-11-24T16:56:30 < fenugrec> karlp , yeh if you want to do a gateswap or pinswap, that garbage gets old really fast.

2017-11-24T16:56:48 < Steffanx> PaulFertser: hmm interesting. Nice how i seem to learn new things daily :P
2017-11-24T16:59:26 < Steffanx> Dont you consider black friday as racism ReadErr? Such name..
2017-11-24T16:59:32 < englishman> k renewed

2017-11-24T17:01:26 < Steffanx> PaulFertser, it seems to be installed the wrong way by default then.
2017-11-24T17:01:39 < ReadErr> Steffanx: why you think ovh is for skiddies only?
2017-11-24T17:01:43 < Steffanx> Yes.
2017-11-24T17:01:58 < ReadErr> but why
2017-11-24T17:02:08 < englishman> ovh is gr8

2017-11-24T17:03:32 < ReadErr> prices are goin up next month too by a dolla
2017-11-24T17:05:55 < karlp> fenugrec: well, haven't had enough experience with gateswap or pinswap functionality in enough other places yet, so... maybe will deal with that then?

2017-11-24T17:12:05 < Steffanx> this is not comedy central
2017-11-24T17:12:13 < tr0ubl3> I use ovh for my bouncer and my website its good enough and cheap
2017-11-24T17:13:16 < ReadErr> tr0ubl3: the price goes up in dec
2017-11-24T17:13:25 < ReadErr> so renew to save $
2017-11-24T17:13:36 < ReadErr> and blackfriday is 50% off for a year
2017-11-24T17:14:31 < tr0ubl3> Hm I am only paying £2-3 a month so not really that bothered about a small increase
2017-11-24T17:14:42 < englishman> yeah the $3 one isnt on sael
2017-11-24T17:15:13 < ReadErr> ya it is
2017-11-24T17:15:20 < ReadErr> its 2.something

2017-11-24T17:17:56 < englishman> wat
2017-11-24T17:18:01 < englishman> its going to $^?
2017-11-24T17:18:03 < englishman> $6?
2017-11-24T17:18:15 < ReadErr> its going to be 4.50
2017-11-24T17:18:19 < ReadErr> muricans
2017-11-24T17:18:24 < ReadErr> up from 3.50
2017-11-24T17:18:25 < englishman> i cant renew the one i have with this
2017-11-24T17:18:30 < ReadErr> nah you cant
2017-11-24T17:18:34 < englishman> meh
2017-11-24T17:18:45 < ReadErr> but migrating is just an rsync
2017-11-24T17:18:53 < ReadErr> pretty much
2017-11-24T17:19:00 < ReadErr> ips move over
2017-11-24T17:19:00 < englishman> im already good til june 2018 tho
2017-11-24T17:19:04 < ReadErr> ah
2017-11-24T17:19:09 < englishman> so why dont i buy 12 months now
2017-11-24T17:19:17 < englishman> at 3.5
2017-11-24T17:19:32 < englishman> then il be good til trump's 2nd term
2017-11-24T17:19:59 < englishman> and the ips i paid for il keep
2017-11-24T17:20:32 < tr0ubl3> Its going to be 4.50 GBP? I am paying 3 GBP for it at the moment
2017-11-24T17:20:48 < englishman> yeah kind of dumb for a $3 vps to charge $5
2017-11-24T17:20:54 < englishman> then its not a $3 vps anymore
2017-11-24T17:20:54 < ReadErr> tr0ubl3: its going up 1$
2017-11-24T17:21:03 < ReadErr> or maybe its 1 currency
2017-11-24T17:21:09 < ReadErr> 1gbp/1dollar

2017-11-24T17:22:02 < ReadErr> its stilll a good deal
2017-11-24T17:22:11 < englishman> yeah they are reliable as fuck
2017-11-24T17:22:13 < ReadErr> resource wise and network integrity
2017-11-24T17:22:21 < englishman> way better than digitalocean
2017-11-24T17:22:25 < ReadErr> ddos protection

2017-11-24T17:39:16 < DelvingDeeper> So.... my clock lines go active and I can see that the mcu sends commands to my micro SD, although it doesn't seem to respond. I checked the blocksize,blocknbr, relcardadd and their all 0. hence my writes and reads are failing. Is there a function I'm suppose to call to get the SDcard's specifications? here's an example of the sdcard parameters that return 0. uint32_t size1 =hsd2.SdCard.BlockSize;

2017-11-24T18:03:18 < Thorn> no it's actually 6V max
2017-11-24T18:04:19 < Thorn> I tested the tvs and it starts to conduct significant current @ about 6.9V
2017-11-24T18:04:32 < Thorn> (one sample only of course)
2017-11-24T18:06:25 < DelvingDeeper> thron: Really depends on its specs, if its meant to short current to ground at 6.9V then it's doing its job?

2017-11-25T03:28:19 < kakimir> so event group is basically a variable to write to and queue is like a fifo line of variables or something?
2017-11-25T03:29:25 < kakimir> I don't yet know what difference it makes to use event group over variable
2017-11-25T03:29:32 < kakimir> but surelly there is a reason
2017-11-25T03:30:55 < kakimir> maybe use of auxiliary functions you don't need to write yourself

2017-11-25T14:03:11 < jpa-> maybe your sample time is too short?
2017-11-25T14:12:25 < invzim> nah, set it to 480 samples
2017-11-25T14:12:40 < invzim> doing dma, it goes in the order of the rank right?
2017-11-25T14:14:07 < invzim> could be a hw issue
2017-11-25T14:14:16 < invzim> I blame cube and st libs of course
2017-11-25T14:15:07 < jpa-> is your 3.3V accurate?

2017-11-25T16:49:52 < karlp> kakimir: with some of the mechanisms in freertos, it's because some of them have been there for years,a nd some of them are much newer,
2017-11-25T16:50:19 < karlp> also, some of the more "featureful" ones, used to often have more flash usage for instance,
2017-11-25T16:50:27 < karlp> so there's quite a few ways of doign a lot of things in freertos
2017-11-25T16:51:07 < kakimir> fat32
2017-11-25T16:51:09 < kakimir> sd cards
2017-11-25T16:51:14 < kakimir> netwroking
2017-11-25T16:51:29 < karlp> well, most of that you have to pay extra for
2017-11-25T16:51:47 < kakimir> what stops using lwip
2017-11-25T16:53:50 < invzim> allright, screw you cube - bug where generated code only set #samples on first rank in generated code
2017-11-25T16:57:18 < kakimir> no messing with cube with lpc

2017-11-25T17:02:00 < Laurenceb_> tbh Trump needs to build a wall to keep the muricans confined
2017-11-25T17:03:41 < invzim> man, and enabling vbat adc also messes up vrefint reading
2017-11-25T17:04:07 < karlp> you really need to be careful with the sampling times for those internal channels.
2017-11-25T17:04:25 < invzim> it seems flaky
2017-11-25T17:04:30 < Laurenceb_> invzim: but stm32 is still better than atmel adc
2017-11-25T17:04:36 < Laurenceb_> *stm32 adc
2017-11-25T17:04:48 < invzim> first, the bug was in the C code - cube didn't respect the parameters set in gui
2017-11-25T17:04:59 < Laurenceb_> there is crosstalk from gpio to adc on F1 for some reason
2017-11-25T17:05:04 < invzim> second, if vbat sampling is enabled, vref int goes back to being flaky
2017-11-25T17:06:55 < kakimir> is your vbat in spec range?
2017-11-25T17:07:21 < kakimir> and a actual battery
2017-11-25T17:07:23 < kakimir> and cap
2017-11-25T17:07:52 < invzim> nah, just decoupled and fed from supply
2017-11-25T17:08:24 < kakimir> try with battery
2017-11-25T17:08:26 < invzim> something about a flag that needed to be enabled, and it being divided by 2 - fine, but why should reading it affect vrefint..
2017-11-25T17:08:41 < invzim> I just want to read the actual supply voltage
2017-11-25T17:09:36 < karlp> you can't. you read vrefint, and you read vrefintcal to work out what vdda is.
2017-11-25T17:10:29 < invzim> yes
2017-11-25T17:10:47 < invzim> but I seem to remember it being internally regulated, clamped to max 3.3V or something
2017-11-25T17:11:10 < invzim> any - seems that vdda does what I need it to do
2017-11-25T17:11:19 < invzim> someone else can struggle with vbat
2017-11-25T17:11:22 < invzim> :)
2017-11-25T17:12:17 < invzim> reads up 4V at least, not going to push it any further

2017-11-25T18:15:31 < Rickta59> I just noticed a new thing in System Workbench. It has a checkbox for "Shareable ST-Link" debugging. I installed the host software and it seems to work great. It finds all the boards I have plugged in and I can easily select which one I want to use.
2017-11-25T18:16:25 < Rickta59> It talks about providing multiple application access to the stlink device. It mentions SWV access. Has anyone seen this software and is there another host application that lets me view the SWV data?
2017-11-25T18:16:54 < Rickta59> I've searched all over the st site but not seen anything that seems like it will work with this
2017-11-25T18:17:42 < Rickta59> https://my.st.com/content/my_st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-performance-and-debuggers/st-link-server.html that is the software for the st-link server

2017-11-25T18:28:56 < karlp> there's quite a few host tools that can do things with swv, question is what you want to do with the data.
2017-11-25T18:29:19 < Rickta59> i was specifically looking for things that work with this tool
2017-11-25T18:29:48 < Rickta59> getting swo output would be nice from the stlink
2017-11-25T18:31:01 < karlp> that's been possible for at least a couple of years now :)
2017-11-25T18:31:07 < Rickta59> with an stlink?
2017-11-25T18:31:11 < karlp> yes
2017-11-25T18:31:15 < Rickta59> ok ... didn't know that
2017-11-25T18:31:24 < karlp> even the windows stlink utility has had swv viewe pane for a couple of years now
2017-11-25T18:31:31 < Rickta59> what about linux?
2017-11-25T18:31:41 < Rickta59> it is something in openocd?
2017-11-25T18:31:49 < karlp> openocd has been able to capture swo from the stlink to a binary file, various tools can parse it in various ways.
2017-11-25T18:31:57 < Rickta59> k
2017-11-25T18:31:59 < Rickta59> thanks
2017-11-25T18:32:16 < karlp> orbuculum is one that is kinda new and cute and acts as a mirror for it, so you can plug in multiple consumers,
2017-11-25T18:32:45 < karlp> swodec is another, there's one in openocd/contrib dir, btu it's not as robust,
2017-11-25T18:32:54 < Rickta59> https://github.com/mubes/orbuculum this thing?
2017-11-25T18:33:02 < karlp> yeah, I've been using that a bit recently.
2017-11-25T18:33:24 < karlp> add line like "tpiu config internal swo.dump.log uart off 32000000
2017-11-25T18:33:28 < karlp> " to your openocd.cfg
2017-11-25T18:33:31 < Rickta59> ok thanks
2017-11-25T18:33:38 < karlp> then orbuculum -f swo.dump.log
2017-11-25T18:34:02 < karlp> then you can use the orb tools, like "orbcat -c 0,%c" to start printing out channel 0 formatted as characters for instance.
2017-11-25T18:34:41 < karlp> or, turn on dwt_pc_sampling with this: http://palmtree.beeroclock.net/~karlp/trace-helpers.cfg
2017-11-25T18:34:52 < karlp> and then you can use "orbtop blah.elf"
2017-11-25T18:35:19 < Rickta59> nice
2017-11-25T18:35:26 < karlp> that mubes blog dude has some more examples,
2017-11-25T18:36:43 < karlp> https://asciinema.org/a/Qf9rJtGtDJqDEKfKVpK2angkj
2017-11-25T18:37:05 < karlp> the "nc -k 9999" bit there isn't needed anymore, mubes fixed it for me to follow the file properly
2017-11-25T18:37:47 < Rickta59> orbtop is a function profile thing?
2017-11-25T18:38:13 < karlp> dwt can put pc samples out on the SWO pin,
2017-11-25T18:38:32 < karlp> orbtop takes pc samples and an elf and makes a pseudo top thing showing which samples are hitting the most,
2017-11-25T18:38:37 < karlp> (watch the video I linked)
2017-11-25T18:38:55 < Rickta59> * heh .. didn't realize that was a video
2017-11-25T18:39:43 < karlp> but yeah, the setup's easier now, mbes made it follow file properly, inthatatemo I was faking out opeocd+stlink-> file o look like a segger jlink server
2017-11-25T18:39:49 < Rickta59> really nice
2017-11-25T18:41:04 < Rickta59> thanks great stuff
2017-11-25T18:41:14 < karlp> yeah, just not well known realy unfortunately.
2017-11-25T18:42:30 < Rickta59> heh .. and here i am toggling pins in the routines i want to measure
2017-11-25T18:44:23 < karlp> heh, yeah, stop
2017-11-25T18:44:44 < karlp> at the very least, you can do things like itm_write(timing_channel, DWT_CYCCNT)
2017-11-25T18:45:09 < karlp> you can actually get DWT to insert timestamps on events, but I've not figured out how to make that happen easily yet,
2017-11-25T18:45:48 < karlp> so I still do kinda lame, "before = DWT_CYCCNT; do_stuff(); itm_write(TIMING_TASK_A, DWT_CYCCNT - before);"
2017-11-25T18:46:02 < karlp> but that's "easy" to do, and pretty low intrusion
2017-11-25T18:46:54 < Rickta59> yeah in the past I've just put start stop captures of CYCCNT and use the debugger to look at the difference
2017-11-25T18:47:09 < karlp> when I get more cleverer, then you make dwt add timestamps, and just do itm_write(TIMING, TASK_ID|TASK_ENTER) and itm_write(TIMING, TASKID|TASK_EXIT) but that'slater...
2017-11-25T18:47:23 < karlp> getting those timings streaming out of swo is much nicer
2017-11-25T18:47:28 < karlp> then you can even start to plot them :)
2017-11-25T18:47:32 < Rickta59> absolutely
2017-11-25T18:47:38 < Rickta59> thanks
2017-11-25T18:48:39 < Rickta59> so I guess that is why my interest was piqued when I saw that st was supporting something new
2017-11-25T18:49:04 < karlp> yeah, st thing looks kinda handy still,
2017-11-25T18:49:30 < karlp> very definitely setup so that people can get to the trace data without having to be the debug owner I'd imagine
2017-11-25T18:50:06 < Rickta59> i couldn't find anything that describes the protocol they are using on port 7184
2017-11-25T18:53:35 < karlp> might just be expecting the raw usb commands, just over tcp isntead of usb?
2017-11-25T18:53:45 < karlp> but yeah, not very clear it is it.
2017-11-25T18:54:02 < Rickta59> maybe the other features are in the pipeline
2017-11-25T18:54:26 < Rickta59> it does come with windows, os/x and linux exes
2017-11-25T18:54:37 < Rickta59> os/x kind os suprised me from st
2017-11-25T18:56:10 < karlp> nah, once you decide you'll do cross platform, it just happens for all three automatically.
2017-11-25T18:56:19 < karlp> osx/linux are close enough if you take care what apis you use.
2017-11-25T18:57:07 < Rickta59> i thought usb support on os/x was a pain?
2017-11-25T18:57:27 < Rickta59> * or at least keeping it working across all the different os/x versions

2017-11-25T19:36:29 < kakimir> what if I need faster switching between tasks than tick?
2017-11-25T19:36:53 < kakimir> or that tick doesn't have enought resolution for it
2017-11-25T19:37:06 < kakimir> I utilize manually a timer?
2017-11-25T19:37:30 < kakimir> ISR then sets some shiet and yeilds?
2017-11-25T19:38:14 < kakimir> or is there a infrastructure for timers other than tick in freertos?
2017-11-25T19:39:03 < karlp> if you think you need fsater switching, you should consider what you're trying to do
2017-11-25T19:40:58 < kakimir> let's say some sensor read requires quite fast operations
2017-11-25T19:41:02 < kakimir> and quite accurate
2017-11-25T19:41:38 < kakimir> but it's not sensible to 1) block while it happens 2) bring tick down too much
2017-11-25T19:41:53 < karlp> you can have your own interrupts that are higher priority than freertos, there's notes that explain how to have you rown code besdie it.
2017-11-25T19:42:11 < karlp> if it's so strict, surely you're blockign everything else while doing it anway?
2017-11-25T19:42:21 < kakimir> well
2017-11-25T19:42:23 < kakimir> most of time
2017-11-25T19:42:51 < kakimir> if we concider all the overheads it would have if it was brought back to rtos tasking
2017-11-25T19:44:26 < kakimir> or if not most of the time - notable time
2017-11-25T19:46:10 < kakimir> and it wouldn't probably be highest priority task
2017-11-25T19:46:21 < kakimir> if there was some real time power control running
2017-11-25T19:46:48 < kakimir> 1ms or so blocking would be clear glitch
2017-11-25T19:47:30 < kakimir> should real time power control loops be using ticks?
2017-11-25T19:49:05 < kakimir> I bet not
2017-11-25T19:49:30 < kakimir> ticks are more like for general interfacing and such

2017-11-25T20:05:52 < DelvingDeeper> ok...so I seem to pass every initialize phase( BSP_SD_Init(void)) although reading and writing always fails.. it seems that the hsd2.SdCard.BlockSize; and every other hsd2.SDCard variable remains zero, should I in some way send a command to the sdcard to retrieve these?

2017-11-25T22:05:33 < kakimir> nah
2017-11-25T22:25:50 < Cracki> well freertos is a bunch of data structures and api calls
2017-11-25T22:26:11 < Cracki> those calls can have return codes, so runtime errors can happen, if you use those
2017-11-25T22:26:34 < Cracki> newest freertos can use lots of static allocations, so you know at compiletime how much memory you need
2017-11-25T22:27:05 < Cracki> as for "compile time errors", it's C code, the compiler will treat it as such
2017-11-25T22:28:04 < Steffanx> Yeah, i like how they did that. The static memory allocation.
2017-11-25T22:28:14 < Steffanx> Finally.
2017-11-25T22:33:45 < Cracki> pretty obvious really. just split the existing implicit heap allocation out of the functions
2017-11-25T22:34:01 < Cracki> quess they just needed a push
2017-11-25T22:34:21 < Steffanx> i didnt mean how, more like: finally they did it. :P

2017-11-25T23:06:45 < Cracki> give some context please
2017-11-25T23:06:55 < kakimir> you don't know rom based uart functionality?
2017-11-25T23:07:40 < kakimir> it just does everything in this magic bax of rom based binary
2017-11-25T23:07:40 < Cracki> what does ROM have to do with uarts?
2017-11-25T23:07:59 < kakimir> it might have the driver
2017-11-25T23:09:06 < Cracki> is that stm32?

2017-11-25T23:33:40 < markus-k> the ssd1306 is a rather simple chip to write a lib for I'd say, especially if you don't want to support every configuration possible but just what you need

2017-11-26T00:22:48 < kakimir> uart_put_line(...) could be used for non blocking read operations, but I could only use it for one-byte-"lines" as I do not know how long the blocks to be received are and there obviously is no way to stop a line read operation in a "clean" manner before the line buffer is full or an end condition is fulfilled.
2017-11-26T00:23:00 < kakimir> shit
2017-11-26T00:24:24 < kakimir> that is retarded
2017-11-26T00:25:08 < kakimir> it's actually blocking until whole buffer is full
2017-11-26T00:27:13 < kakimir> you need to store context manually at least
2017-11-26T00:27:30 < kakimir> then restore it when interrupt is called
2017-11-26T00:27:50 < kakimir> they say nothing in documentation

2017-11-26T01:43:23 < dongs> have you actually bothered looking at its code?
2017-11-26T01:43:53 < dongs> DelvingDeeper: SD code in stdperiph and in HAL works, more or less.
2017-11-26T01:44:00 < dongs> if something isn't working, the problem is on your side
2017-11-26T01:46:11 < DelvingDeeper> dongs: I have, it seems to pass into a section and then exits to a hard fault. Just not sure what its checking. There does seem to be a lot of reported issues with the SD_PowerOn function and I've asked on stmcommunity, one of the mods replied and said there is multiple issues that their sorting out. Just trying to figure out why its hitting a hardfault.
2017-11-26T01:48:07 < DelvingDeeper> The section of code is commented with " /* Send ACMD41 SD_APP_OP_COND with Argument 0x80100000 */" and I honestly don't know wtf that means
2017-11-26T01:48:08 < dongs> so step t hrough it
2017-11-26T01:48:09 < dongs> until it hardfaults
2017-11-26T01:48:57 < DelvingDeeper> I did, I'll see if there's any documentations on what commands this function sends to the sdcard. It bums out to a hardfault right after the command is sent
2017-11-26T01:49:38 < dongs> step into sendign the command then?
2017-11-26T01:52:32 < dongs> or actually look at the registers / stack trace in ahrdfault and see what caused it
2017-11-26T01:54:33 < DelvingDeeper> Dongs: I have checked the SDMMC registers but can't see anything of value, It resets everything to 0x0. Not sure what you mean by stack trace..

2017-11-26T01:59:49 < dongs> is SD peripheral even powered on

2017-11-26T03:03:27 < dongs> a bit fancier
2017-11-26T03:03:55 < invzim> how do you bond it to the pcb, glue?
2017-11-26T03:05:27 < dongs> me? I just hold it, there, i'm sure there's a jig that keeps the assembly in place
2017-11-26T03:05:32 < invzim> for my board, I think the modules are path of least resistance
2017-11-26T03:05:35 < dongs> the oled screen has pegs
2017-11-26T03:05:38 < dongs> the flex pcb
2017-11-26T03:05:40 < dongs> er peg holes
2017-11-26T03:05:50 < dongs> so a jig is probably made that pokes through pcb/flexpcb to keep it aligned
2017-11-26T03:06:54 < invzim> if they made them with fpc I MAY have considered it, this is just super low volume hobby stuff for me anyway
2017-11-26T03:07:43 < dongs> what do you mean? you can buy raw screens with flexpcb tail, which is wrapped around the "base" pcb in the thing you have
2017-11-26T03:07:46 < dongs> https://ae01.alicdn.com/kf/HTB10wkzIpXXXXcYXVXXq6xXFXXXa/NoEnName-Null-Raspberry-Pi-0-96-inch-White-OLED-Display-Screen-Module-SSD1306-Drive-IC-SPI.jpg
2017-11-26T03:08:16 < dongs> thats the kind i got, just the raw panel w/flex, it needs half a dozen caps on the carrier board to be usable
2017-11-26T03:11:54 < invzim> cheaper and easier for me to just buy the modules :) ali prices seem to be about the same with or without pcb

2017-11-26T05:24:44 < qwebirc9433> Hey everybody! Simple q: I connected yelow led to stm32f3 pin and I see led is not fully turned on - I used 48ohm resistor. scope snapshot: https://photos.app.goo.gl/sABIKH2uhBFyqKti1 - what i am doing wrong?
2017-11-26T05:25:31 < qwebirc9433> is it because stm32 cannot drive this led or why ?
2017-11-26T05:28:15 < Cracki> how much current does it need?
2017-11-26T05:28:32 < Cracki> how much current does the data sheet of your stm32f3 say the pin can source/sink?
2017-11-26T05:28:46 < Cracki> it's likely that you overload your pin
2017-11-26T05:29:03 < dongs> if its a standard 0805 or wahtever led theres no problem
2017-11-26T05:29:08 < Cracki> those 2.2 volts look ok for an LED
2017-11-26T05:29:12 < dongs> 38R is on the low side for a led but wahtever
2017-11-26T05:29:19 < dongs> its gonna be bright
2017-11-26T05:29:24 < Cracki> the stm32 might not be able to source/sink the current
2017-11-26T05:29:37 < Cracki> who says it's a 0805 led?
2017-11-26T05:29:56 < Cracki> ah _if_ right
2017-11-26T05:30:25 < Cracki> qwebirc9433, show the circuit
2017-11-26T05:31:19 < dongs> ya, if
2017-11-26T05:31:23 < Cracki> got some datasheet here, says +- 25 mA
2017-11-26T05:31:31 < Cracki> and +-80 total
2017-11-26T05:31:33 < dongs> i mean if he hooks up a 1W yellow led to gpio pin then ya

2017-11-26T05:31:45 < Laurenceb_> STEAM
2017-11-26T05:32:00 < qwebirc9433> there is 48Ohm resistor in front of it
2017-11-26T05:32:03 < Cracki> qwebirc9433, what led do you use
2017-11-26T05:32:07 < qwebirc9433> yellow
2017-11-26T05:32:08 < dongs> is it 2.2K or 38R
2017-11-26T05:32:24 < Cracki> what is the voltage right at the pin of the stm32?
2017-11-26T05:32:30 < qwebirc9433> 47 Ohm sorry....
2017-11-26T05:32:57 < dongs> http://img.dxcdn.com/productimages/sku_270869_1.jpg here's a yellow led
2017-11-26T05:33:22 < qwebirc9433> it is 3V, than drops like I showed on picture...
2017-11-26T05:33:47 < Cracki> 3.3 or 3.0?
2017-11-26T05:34:10 < dongs> anywa,y i prefer sinking leds with MCUs
2017-11-26T05:34:13 < dongs> rather than sourcing
2017-11-26T05:34:18 < Cracki> can you measure the current through that?
2017-11-26T05:35:07 < qwebirc9433> I can measure voltage in front of led and after led

2017-11-26T05:35:34 < Laurenceb_> we need moar STEAM educators in society
2017-11-26T05:35:52 < Cracki> important is the current on that pin
2017-11-26T05:35:56 < qwebirc9433> what is max current it can drive?
2017-11-26T05:36:04 < qwebirc9433> stm32f3'
2017-11-26T05:36:04 < Cracki> stem+arts is cancer
2017-11-26T05:36:13 < Cracki> qwebirc9433, max current might be 25 mA
2017-11-26T05:36:25 < Cracki> table 22 http://www.st.com/content/ccc/resource/technical/document/datasheet/f2/1f/e1/41/ef/59/4d/50/DM00058181.pdf/files/DM00058181.pdf/jcr:content/translations/en.DM00058181.pdf
2017-11-26T05:36:39 < Cracki> **absolute maximum ratings**
2017-11-26T05:36:39 < qwebirc9433> it is 2V in front of led
2017-11-26T05:36:46 < Cracki> don't care about the voltage
2017-11-26T05:36:50 < Cracki> current is important
2017-11-26T05:36:57 < Cracki> measure voltage across the resistor plz
2017-11-26T05:37:26 < Cracki> I = U / R
2017-11-26T05:38:09 < englishman> lol you're not going to answer any important questions are you qwebirc9433
2017-11-26T05:38:19 < qwebirc9433> 1V on 47 ohm resistor...
2017-11-26T05:38:34 < Cracki> that's 21.3 mA
2017-11-26T05:38:39 < Cracki> that's *close* to the max rating
2017-11-26T05:38:44 < Cracki> so I'd say you're torturing the pin
2017-11-26T05:38:52 < dongs> Cracki: i donno man
2017-11-26T05:39:01 < dongs> im driving 11 pink leds from F0 gpio
2017-11-26T05:39:03 < dongs> wiht 33R
2017-11-26T05:39:07 < Cracki> must be good leds
2017-11-26T05:39:10 < dongs> it seems to do just fine
2017-11-26T05:39:14 < dongs> well, they're amazing cuz theyre pink
2017-11-26T05:39:15 < Cracki> I know my boss uses smd leds that are quite efficient
2017-11-26T05:39:23 < Cracki> qwebirc9433, what kinda led is that?
2017-11-26T05:39:28 < qwebirc9433> I have smd led - but ellow
2017-11-26T05:39:32 < qwebirc9433> yellow
2017-11-26T05:39:59 < qwebirc9433> hmm... sory dont have spec - I just picked it up from drawer...
2017-11-26T05:40:07 < dongs> what hte fuck does it look ilke
2017-11-26T05:40:10 < Cracki> well it won't get brighter anyway because beyond 25 mA, you're killing the stm32
2017-11-26T05:40:10 < dongs> a 5mm round led?
2017-11-26T05:40:33 < qwebirc9433> now its rectangular
2017-11-26T05:40:42 < Cracki> >changes shape
2017-11-26T05:40:45 < dongs> "now"?
2017-11-26T05:40:50 < dongs> you filed it off?
2017-11-26T05:40:53 < Cracki> w = ,
2017-11-26T05:41:24 < Cracki> might be one of those bright thingies with larger surface
2017-11-26T05:41:32 < Cracki> not the normal "point light sources"
2017-11-26T05:41:34 < Cracki> but who knows
2017-11-26T05:41:37 < dongs> i recall some project where i had to file leds
2017-11-26T05:41:39 < qwebirc9433> will make video for you guys... :)
2017-11-26T05:41:40 < Cracki> qwebirc9433, post a picture of the led
2017-11-26T05:41:44 < dongs> because faggots didnt think of clearance
2017-11-26T05:41:45 < dongs> when making hte pcb
2017-11-26T05:41:58 < dongs> and 5mm round leds dont work together when pitch is like 4mm ebtween them
2017-11-26T05:42:01 < Cracki> filed an IR photodiode to make it flat for an ir uart dongle
2017-11-26T05:42:10 < qwebirc9433> https://photos.app.goo.gl/wzYnwXgU5ige9e5U2
2017-11-26T05:42:28 < Cracki> hah
2017-11-26T05:42:31 < Cracki> that led is huge
2017-11-26T05:42:37 < Cracki> with 20 mA it won't do much
2017-11-26T05:42:47 < Cracki> that's the best you'll get
2017-11-26T05:43:27 < Cracki> consider NOT driving that led directly from a GPIO pin.
2017-11-26T05:43:42 < dongs> yeah
2017-11-26T05:43:48 < Cracki> it'll be ok like this, but it's close to the max rating of the stm32
2017-11-26T05:44:12 < qwebirc9433> still dont know why voltage drops like so...
2017-11-26T05:44:23 < Cracki> because the pin can't source this much current
2017-11-26T05:44:53 < qwebirc9433> but 20ma is below max curr...
2017-11-26T05:44:53 < Cracki> or do you mean the voltage across the led?
2017-11-26T05:45:15 < Cracki> leds are supposed to have "stable" voltages around 2-3 volts
2017-11-26T05:45:20 < Cracki> depending on color and such
2017-11-26T05:45:20 < qwebirc9433> acros led is 2V
2017-11-26T05:45:31 < Cracki> and 2 volts across that led is probably right.
2017-11-26T05:45:34 < qwebirc9433> that can be seen from scope picture I posted
2017-11-26T05:45:50 < qwebirc9433> ok will put 100 Ohm...
2017-11-26T05:45:53 < Cracki> the remaining voltage goes across the resistor to limit the current
2017-11-26T05:45:59 < qwebirc9433> I gues it will be still bright enough
2017-11-26T05:46:26 < Cracki> 100 ohm is probably 10 mA then
2017-11-26T05:46:33 < Cracki> that's a good safe value
2017-11-26T05:49:03 < qwebirc9433> ugh.... no - its still the same...
2017-11-26T05:49:12 < qwebirc9433> something else is not right...
2017-11-26T05:50:52 < qwebirc9433> maybe because I initialized it as GPIO_MODE_OUTPUT_PP ?
2017-11-26T05:51:06 < qwebirc9433> should I put it to: GPIO_MODE_OUTPUT_OD

2017-11-26T05:58:23 < Cracki> OD is open drain, that _could_ help, but then you'd have to put the gpio pin on the negative side of the led
2017-11-26T05:58:31 < Cracki> qwebirc9433, see above
2017-11-26T05:58:48 < qwebirc9433> ok

2017-11-26T05:58:57 < qwebirc9433> sorry to bother...
2017-11-26T05:59:06 < dongs> what was it
2017-11-26T05:59:13 < Cracki> open drain tends to be able to sink more current, but it can't source current. also, the max limits still apply.
2017-11-26T05:59:16 < Cracki> yes, what was it
2017-11-26T05:59:28 < qwebirc9433> if ((int) ((float) HAL_GetTick() / 1000) % 2 == 0) HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);
2017-11-26T05:59:30 < qwebirc9433> :)
2017-11-26T05:59:35 < Cracki> yes that helps
2017-11-26T05:59:36 < dongs> ...
2017-11-26T05:59:43 < dongs> i don't even
2017-11-26T05:59:45 < Cracki> now twice as bright
2017-11-26T05:59:50 < qwebirc9433> it keeps togling pin when seconds are even :)
2017-11-26T05:59:52 < dongs> why teh fuck do you have it on PA8 if youre not gonna use a fucking timer to toggle it
2017-11-26T06:00:27 < qwebirc9433> :) it is easier to wire it that way
2017-11-26T06:00:40 < qwebirc9433> I added led just in latest version of my pcb :)
2017-11-26T06:00:44 < Cracki> this should have sometimes resulted in the led staying _on_ instead of _off_ for a second
2017-11-26T06:01:02 < Cracki> unless that code is executed exactly an even number of times
2017-11-26T06:01:58 < Cracki> IP is from slovenia
2017-11-26T06:02:03 < Cracki> interesting
2017-11-26T06:02:08 < qwebirc9433> no, it does exactly how it is programed - it togles it every loop... this is aprox 2uS as seen from scope picture :9
2017-11-26T06:02:10 < dongs> that "code" should have resulted in the "programmer" going straight to the oven
2017-11-26T06:02:54 < qwebirc9433> have mercy people... I layed out almost all my work and you are so... ...
2017-11-26T06:02:57 < Cracki> :P
2017-11-26T06:03:11 < Cracki> tbh I should have noticed the time base on the scope picture
2017-11-26T06:03:22 < qwebirc9433> anyway sorry to interrupt more clever topics... thanks ALL!

2017-11-26T06:06:02 < dongs> qwebirc9433: enable TIM1_CH1 on PA8 and drive that led with that
2017-11-26T06:06:10 < dongs> why waste CPU time on PWM if you can do it for free wiht existing hardware
2017-11-26T06:07:06 < qwebirc9433> dongs: you are right! will take your comments into account thank you.
2017-11-26T06:09:17 < Cracki> not sure pwm was even intended... :P

2017-11-26T16:35:19 < kakimir> port will close after being set low, which result in module
2017-11-26T16:35:20 < kakimir> functions reduction.
2017-11-26T16:35:31 < kakimir> so I bind it to 3v3 directly
2017-11-26T16:35:39 < kakimir> should have serial port functionality?

2017-11-26T17:08:39 < kakimir> no luck
2017-11-26T17:08:50 < kakimir> tried nrf toolkit, uart and lightblue
2017-11-26T17:13:03 < Getty> I have a very very very strange problem, which drives me crazy now since some months, and i cant find it. Out of nowhere vector.c of libopencm3 sets a bool in my code (which triggers a reboot) while nothing in my code sets this bool.
2017-11-26T17:13:48 < Getty> now the joke is, that the problem is gone if i exclude specific parts of my code (its not even about that they get called, just removing them is enough, having them unused isnt)
2017-11-26T17:15:21 < Getty> I have the feeling, that somewhere in my (or libopencm3 or lwip) codes someone calls some totally wrong address for a function, and with me adding those code parts i move the libopencm3 lib into that wrong address range and then get this effect
2017-11-26T17:15:34 < Getty> does that make sense?
2017-11-26T17:15:41 < qyx> why should vector.c does it
2017-11-26T17:15:49 < Getty> i have no idea! thats what the debugger tells me
2017-11-26T17:15:53 < Getty> i assume its more a side effect
2017-11-26T17:16:01 < Getty> a wrong call to vector.c through this, that then leads to this change
2017-11-26T17:16:12 < Getty> (i dont touch vector.c myself of course)
2017-11-26T17:16:21 < Getty> sadly i cant get a stacktrace on the debugger ;)
2017-11-26T17:16:34 < Getty> that wold be VERY helpfull
2017-11-26T17:16:43 < Thorn> why not?
2017-11-26T17:17:07 < Steffanx> You do see the device kakimir?
2017-11-26T17:17:12 < Steffanx> and you can connect?
2017-11-26T17:17:57 < Getty> kakimir?
2017-11-26T17:18:17 < kakimir> not in tools
2017-11-26T17:18:26 < kakimir> just in bluetooth search
2017-11-26T17:18:40 < Getty> oh that wasnt for me lol
2017-11-26T17:19:00 < Getty> Thorn: aehm as far as i understood my processor is not capable of dellivering stacktrace or in combination with the openocd
2017-11-26T17:19:12 < Getty> Thorn: if i am not wrong, of course i am open to someone showing me otherwise
2017-11-26T17:19:31 < Thorn> all stm32 chave enough debug hardware for that
2017-11-26T17:19:37 < Thorn> *have
2017-11-26T17:19:39 < Getty> ok! then i must have understood something wrong
2017-11-26T17:19:56 < Getty> let me get back to the debugging situation and then we check how we get that stacktrace
2017-11-26T17:20:33 < Thorn> you can also set at least 2 (4?) breakpoints
2017-11-26T17:26:35 < Getty> welll more than 1 i cant use
2017-11-26T17:26:39 < Getty> i set the breakpoint on the bool
2017-11-26T17:26:45 < Getty> see that vector.c changes it that was my last stand
2017-11-26T17:26:54 < Getty> i mean making a breakpoint in vector.c is probably nto so wise :D
2017-11-26T17:27:53 < kakimir> I cut the enable wire and still no serial port
2017-11-26T17:28:17 < kakimir> I can not even connect to my debug server with my current network

2017-11-27T10:50:48 < invzim> I need to measure pulse width in the us range, idea is to just have interrupts from gpio and timestamp them with something
2017-11-27T10:51:26 < invzim> is there a cycle counter or something you can use for free?
2017-11-27T10:51:53 < zyp> wat
2017-11-27T10:51:54 < Thorn> timer input capture?
2017-11-27T10:52:03 < zyp> why the fuck would you not use input capture?
2017-11-27T10:52:18 < Thorn> life is not fun eithout interrupt latency and jitter

2017-11-27T10:53:38 < dongs> if you insist.
2017-11-27T10:53:47 < dongs> sample it in EXTI or omsethin
2017-11-27T10:53:59 < dongs> to reduce latency/weirdness maybe grab CYCCNT sample before clearing exti flags
2017-11-27T10:54:10 < dongs> then use that cached value as whatever measurement
2017-11-27T10:54:43 < invzim> will have a look, and also googles input capture :)
2017-11-27T10:55:42 < invzim> it's not hard science here, it's video sync pulse stuff. I want to separate the horizontal syncs which are about 5us from the vertical syncs which are longer
2017-11-27T10:56:11 < dongs> i'd use a timer for that
2017-11-27T10:56:19 < dongs> sounds like it would need to be somewhat accurate
2017-11-27T10:56:40 < invzim> nah, I'm just interested in when a vertical (>5us) occurs

2017-11-27T22:12:04 < zyp> coinfloor perhaps
2017-11-27T22:15:48 < kakimir> should I set initial variables of tasks in freertos as static?
2017-11-27T22:16:00 < zyp> why?
2017-11-27T22:16:01 < kakimir> those that come before while(1)
2017-11-27T22:16:13 < kakimir> I saw some dude to do that in youtub vid
2017-11-27T22:16:36 < zyp> freertos tasks are just functions
2017-11-27T22:16:54 < kakimir> yep
2017-11-27T22:17:05 < zyp> with the standard implications that has for static variables
2017-11-27T22:17:12 < kakimir> it's a beauty
2017-11-27T22:17:30 < zyp> i.e. a static variable would be placed in .data/.bss instead of on stack
2017-11-27T22:18:22 < zyp> if you're starting multiple tasks with the same function, static variables will be shared, which might not be what you want
2017-11-27T22:18:49 < zyp> I'd only use static variables if I explicitly wanted to share them between multiple instances of that task
2017-11-27T22:19:09 < zyp> there's not really any other benefit
2017-11-27T22:19:35 -!- enh [~enhering@191.33.84.84] has quit [Remote host closed the connection]
2017-11-27T22:19:53 < jpa-> it also makes sense for big variables, if you don't want to be increasing the stack
2017-11-27T22:19:59 < zyp> less stuff on stack will of course mean you consume less stack
2017-11-27T22:20:26 < zyp> but increasing .data/.bss by the same amount just means you got that much left room left over for stack anyway
2017-11-27T22:20:32 < jpa-> yeah
2017-11-27T22:20:45 < zyp> so it doesn't really matter unless you allocate those from separate memories
2017-11-27T22:20:47 < kakimir> semaphore is given at it's creation?
2017-11-27T22:20:55 < kakimir> how about counting semaphore?
2017-11-27T22:21:15 < zyp> is it? that doesn't make sense to me
2017-11-27T22:21:28 < kakimir> https://www.freertos.org/FreeRTOS_Support_Forum_Archive/December_2005/freertos_Binary_semaphores_1400492.html
2017-11-27T22:21:31 < zyp> and you might prefer to use task notifications
2017-11-27T22:22:03 < kakimir> If you take a look at semphr.h you will notice that when a semaphore is created, it is immediately "given", so the first call to "take" the semaphore will succeed. If you want to change this behaviour then there are a couple of options.
2017-11-27T22:23:12 < zyp> https://www.freertos.org/xSemaphoreCreateBinary.html
2017-11-27T22:23:14 < zyp> «The semaphore is created in the 'empty' state, meaning the semaphore must first be given using the xSemaphoreGive() API function before it can subsequently be taken (obtained) using the xSemaphoreTake() function.»
2017-11-27T22:23:57 < zyp> anyway, look at task notifications before you spend too much time looking at semaphores
2017-11-27T22:24:13 < kakimir> I have old freertos
2017-11-27T22:24:18 < zyp> why?
2017-11-27T22:24:43 < kakimir> I don't bother to change
2017-11-27T22:24:50 < kakimir> at least first thing
2017-11-27T22:24:52 < zyp> then why do you bother at all?
2017-11-27T22:25:09 < kakimir> I need to make it work first
2017-11-27T22:25:22 < kakimir> then it's better to make new freertos work
2017-11-27T22:25:37 < zyp> why not grab the newest version and make it work instead of putting a bunch of time into making an obsolete version work?
2017-11-27T22:26:09 < kakimir> because obsolete version was provided with all the configuration to run on my platform

2017-11-28T00:55:09 < kakimir> yeh
2017-11-28T01:10:13 < kakimir> I have pro question
2017-11-28T01:10:24 < kakimir> void UART0_IRQHandler(void){ LPC_UARTD_API->uart_isr(uartHandle); //Call ROM-based UART interrupt handler
2017-11-28T01:10:30 < kakimir> }
2017-11-28T01:11:32 < kakimir> I want to set registers for that interrupt handler and read the registers before it exits
2017-11-28T01:13:06 < kakimir> clearly it can't do it's shit right
2017-11-28T01:13:38 < kakimir> it relies on some registers
2017-11-28T01:13:49 < kakimir> output is bullshit
2017-11-28T01:24:49 < kakimir> is there a way to load new binary in target without closing debug session?
2017-11-28T01:28:52 < zyp> yes, «load»
2017-11-28T01:29:13 < zyp> assuming you're using extended-remote with a capable gdbserver

2017-11-28T01:40:33 < kakimir> and then read those before context is switched
2017-11-28T01:40:37 < kakimir> back
2017-11-28T01:45:54 < kakimir> I don't even know what to google
2017-11-28T01:46:46 < kakimir> I think there was such attribute for function call that disables context switch or some overhead

2017-11-28T13:56:16 < tr0ubl3> I dont know the english isnt great on the page
2017-11-28T14:16:50 < kakimir> jpa-: hello
2017-11-28T14:17:11 < jpa-> hi
2017-11-28T14:17:26 < kakimir> I want to do a trick with m3
2017-11-28T14:18:22 < kakimir> save some registers for rom based uart send line
2017-11-28T14:18:43 < kakimir> after it has been called
2017-11-28T14:18:52 < jpa-> "trick: (slang) An act of prostitution." this kind of trick?
2017-11-28T14:19:03 < kakimir> kinda
2017-11-28T14:19:29 < kakimir> then when ISR is called every time place those stored values back
2017-11-28T14:20:01 < kakimir> and when rom handler call inside ISR ends it stores something
2017-11-28T14:20:18 < jpa-> nothing you're saying is making sense
2017-11-28T14:20:25 < jpa-> what's the goal?
2017-11-28T14:21:10 < kakimir> I'm not sure what but tx wont work without while(!transmission_complete) right after rom based send line call
2017-11-28T14:21:35 < kakimir> so I assume it has something to do with registers
2017-11-28T14:21:38 < jpa-> what is "rom based send line call"?
2017-11-28T14:21:53 < kakimir> rom implementation of send line
2017-11-28T14:22:10 < qyx> why are you even trying to get the rom thing working?
2017-11-28T14:22:20 < kakimir> because I'm so close
2017-11-28T14:22:37 < jpa-> it all sounds too stupid
2017-11-28T14:22:44 < kakimir> it is
2017-11-28T14:22:49 < qyx> so trash it
2017-11-28T14:22:52 < jpa-> yeah
2017-11-28T14:22:53 < kakimir> but entertain the idea
2017-11-28T14:22:58 < jpa-> not like you need rom to print a line
2017-11-28T14:23:46 < kakimir> it is so elegant else but for context contamination of tx functionality
2017-11-28T14:24:29 < jpa-> so check registers with debugger before and after the call and check if it is actually doing something wrong?
2017-11-28T14:26:37 < kakimir> I planned to
2017-11-28T14:26:53 < kakimir> it outputs random number of chars
2017-11-28T14:26:58 < kakimir> usually only one
2017-11-28T14:27:10 < kakimir> sometimes 2-3
2017-11-28T14:31:53 < kakimir> how do you even copy the whole set of registers when you need to load address to at least one of them?
2017-11-28T14:32:28 < kakimir> like in your example code for fault capturing

2017-11-28T20:46:39 < Steffanx> Not really useful, no. Just some dog toy thingies for my dad :)
2017-11-28T20:47:13 < Steffanx> I remade something now made of wood that costs a fortune to replace. Now it's just some small amount of printing time.
2017-11-28T20:47:23 < Steffanx> *that was orginally made of wood
2017-11-28T20:47:50 < BrainDamage> ... you give dog treats to your father?
2017-11-28T20:48:20 < Steffanx> i love you too BrainDamage.
2017-11-28T20:50:50 < Steffanx> Next time when i need some of that i'll ask for some hentai BrainDamage :P
2017-11-28T20:52:25 < BrainDamage> covering that fetish is going to be hard, but it's a challenge I'm willing to pick up
2017-11-28T20:55:35 < Steffanx> You had some practice. I know that.

2017-11-28T20:58:24 < Steffanx> Does the ring need to be flexible mr Laurenceb/
2017-11-28T20:58:32 < Laurenceb> yes
2017-11-28T20:58:36 < Laurenceb> SLS nylon
2017-11-28T20:58:47 < Steffanx> oh, PaulFertser does that. I dont do nylon.
2017-11-28T20:59:06 < Laurenceb> yeah I'm going to pay expensive place to make it
2017-11-28T20:59:23 < Steffanx> Did i understand it right that you have to bake nylon filament before you use it, because it likes H2O a bit too much?
2017-11-28T20:59:37 < Laurenceb> probably
2017-11-28T21:00:34 < Steffanx> Im still not sure what it is supposed to be. First thing that came to mind was "cock ring", but .. somehow i think you posted something more serious this time.
2017-11-28T21:00:59 < Laurenceb> its a clamp thingy for connecting stuff to tubes
2017-11-28T21:01:28 < Steffanx> That still fits my first thought.
2017-11-28T21:01:37 < Laurenceb> lel
2017-11-28T21:01:56 < kakimir> is there some define in cm3 or cmsis for lowest priority possible for current chip?

2017-11-28T21:03:00 < PaulFertser> Steffanx: well, that trimmer line I used gave decent results. Some water is good for layer adhesion actually. Only if you need a really smooth surface you'll need to bake it.
2017-11-28T21:03:17 < kakimir> my chip has 3 prio bits
2017-11-28T21:03:55 < kakimir> can I derive lowest priority from that?
2017-11-28T21:04:05 < PaulFertser> iirc there was some method like write all ones, read back...
2017-11-28T21:04:43 < PaulFertser> On stm32 4 higher bits are used for priority. So the lowest would be 0x10.
2017-11-28T21:05:16 < BrainDamage> Laurenceb: you can buy metal screw clamp rings for pipes for less than a dollar here, does it have to be nylon?
2017-11-28T21:05:47 < Laurenceb> yeah maybe I could make an adaptor for jubille clips
2017-11-28T21:05:55 < Laurenceb> I dunno lol
2017-11-28T21:07:37 < kakimir> Eight programmable interrupt priority levels with hardware priority level masking
2017-11-28T21:08:34 < kakimir> so my minimum priority level in freertos needs to be 0x7 instead of 0x1f
2017-11-28T21:09:39 < kakimir> any recommends of placing configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY to right place?
2017-11-28T21:10:00 < kakimir> when I have 8 interrupt priority levels
2017-11-28T21:10:34 < kakimir> what do I need to take account of?
2017-11-28T21:15:46 < kakimir> tick works at configLIBRARY_MAX_SYSCALL_INTERRUPT_PRIORITY priority level?
2017-11-28T21:21:28 < Steffanx> and you, mr PaulFertser, printed something useful? :)
2017-11-28T21:22:38 < Steffanx> something must see that is
2017-11-28T21:22:45 < PaulFertser> Steffanx: kinda, a thing to connect a selfie-stick to a tripod for my friend
2017-11-28T21:23:04 < PaulFertser> Steffanx: also, a tail motor holder for my microheli.
2017-11-28T21:24:18 < PaulFertser> Plenty of enchancements for the printer itself (vibration dampers, frame stiffeners, belt tensioner)
2017-11-28T21:25:14 < Steffanx> I still have to do that.

2017-11-29T03:02:04 < aandrew> if it doesn't have a logo consisting of a gnarly looking gnome with a pickaxe peeking out of a hole I will be sorely disappointed
2017-11-29T03:02:20 < sync> probably not that often realistically
2017-11-29T03:02:46 < aandrew> I bet they never look at the things unless it's time to change the bulb or someting's gone wrong
2017-11-29T03:02:56 < Laurenceb_> uk poles have a cover that fixes on with simple clips, then a standard circuit breaker inside
2017-11-29T03:03:05 < aandrew> there's a light post right outside my house, I discoered I can shine a laser at the light sensor to turn the fucking thing off
2017-11-29T03:03:07 < Laurenceb_> aiui they flip the breaker to change the bulb
2017-11-29T03:03:12 < Laurenceb_> heh
2017-11-29T03:03:30 < sync> if it is lp sodium you can just kick it out
2017-11-29T03:03:37 < sync> or mercury
2017-11-29T03:03:49 < Laurenceb_> you could wire in to the bulb side of the breaker and stick the miner higher up the tube
2017-11-29T03:03:57 < Laurenceb_> ebil :P
2017-11-29T03:04:18 < sync> well, it depends on how they do it
2017-11-29T03:04:24 < sync> most of them are always connected
2017-11-29T03:04:24 < Laurenceb_> do miners need to have continual web access?
2017-11-29T03:04:47 < sync> with some remote control shit
2017-11-29T03:04:49 < sync> yes
2017-11-29T03:04:51 < sync> but you could do PLC
2017-11-29T03:04:52 < Laurenceb_> doh
2017-11-29T03:05:00 < sync> on the low impedance mains #yoyo
2017-11-29T03:05:03 < Laurenceb_> that makes it annoying
2017-11-29T03:05:04 < Laurenceb_> heh
2017-11-29T03:05:24 < sync> but I mean, it is shielded, so it is all fine :D
2017-11-29T03:10:19 < sync> interestingly the CE declaration of PLC devices states that because of the differential nature of the signal transmission interference with other devices is impossible
2017-11-29T03:13:04 < dongs> hey invzim did you ever get a 3d model for that china microsd
2017-11-29T03:14:08 < Laurenceb_> >3d model
2017-11-29T03:14:12 < Laurenceb_> >microsd
2017-11-29T03:14:13 < Laurenceb_> lulwut

2017-11-29T03:15:45 < MrMobius> Laurenceb, you can just walk casually by and link to your miner over bluetooth like gas pump skim scanners do
2017-11-29T03:17:03 < sync> well, I would probably do PLC
2017-11-29T03:17:28 < aandrew> yeah I'd do it wireless. hell you could get cell modems that'd work fine in concrete posts
2017-11-29T03:17:33 < aandrew> metal ones might also work
2017-11-29T03:19:35 < Laurenceb_> some uk posts have GRP inspection covers
2017-11-29T03:19:52 < Laurenceb_> I sense a new blackmarket product
2017-11-29T03:20:15 < Laurenceb_> "coinpole"
2017-11-29T03:22:34 < sync> well you need to shove it in deep
2017-11-29T03:22:41 < sync> so that it can stay hidden
2017-11-29T03:22:49 < Laurenceb_> thats what she said
2017-11-29T03:27:31 < upgrdman> a little lube might help
2017-11-29T03:27:40 < upgrdman> for when you need to shove it in deep

2017-11-29T05:33:53 < jadew> fucking ebay trolls
2017-11-29T05:34:03 < jadew> these chinese fucks are annoying as hell
2017-11-29T05:34:11 < jadew> they put a best offer option but they decline all offers
2017-11-29T05:34:18 < jadew> no counter offers or anything
2017-11-29T05:34:43 < jadew> I offered 240 pounds for this, https://www.ebay.co.uk/itm/T962A-Infrared-Reflow-Oven-Two-Side-Soldering-Windowed-Drawer-Micro-Processor/252721275100
2017-11-29T05:35:08 < jadew> that's a decent offer right? at least it would warrant a counter offer
2017-11-29T05:36:37 < fenugrec> I think they misunderstand the concept, they read it as "make a higher offer than BIN price"
2017-11-29T05:36:46 < jadew> heh
2017-11-29T05:37:31 < jadew> I would have bought it if he countered me 260 btw (which is the full price)
2017-11-29T05:37:41 < jadew> it would have told me that he can't go lower for whatever reason
2017-11-29T05:37:57 < jadew> but this shit? wtf...
2017-11-29T05:38:09 < upgrdman> https://i.redd.it/gurp9n1ift001.jpg
2017-11-29T05:38:53 < fenugrec> jadew fight the good fight : just spam him other offers incrementing by 0.01 every time
2017-11-29T05:39:09 < jadew> fenugrec, you only get 2 tries
2017-11-29T05:39:34 < jadew> I have a feeling all of the other sellers are the same guy anyway
2017-11-29T05:39:34 < fenugrec> heh, too bad. Though they often have multiple listings
2017-11-29T05:39:38 < jadew> or the same organization in china
2017-11-29T05:39:53 < jadew> yeah, they do
2017-11-29T05:40:08 < jadew> in fact, there's another guy who sells for 200 pounds, but only to the UK
2017-11-29T05:40:19 < jadew> and the shipping cost is 61 pounds lol
2017-11-29T05:40:41 < jadew> (to the UK), so basically it's the same shit
2017-11-29T05:40:52 < jadew> I bet they have a warehouse in the UK as well (they usually do)
2017-11-29T05:41:14 < jadew> there seems to be one in Germany and one in the UK

2017-11-29T09:55:02 < jpa-> i'd call it 3-way navigation switch
2017-11-29T09:55:04 < dongs> is it sending some kinda enoder-like graycode shit?

2017-11-29T09:55:57 < jpa-> dongs: nah, it just has separate switches for 11 deg and 21.5 deg
2017-11-29T09:56:01 < dongs> oh okay
2017-11-29T09:56:13 < dongs> so its actually like 4 positions left/right and a click?
2017-11-29T09:56:29 < stvn> gay code
2017-11-29T09:56:36 < jpa-> pins 1 and 4 are the 21.5 deg switch, pins 2 and 3 are the 11 deg switch, and pin Y is the push switch
2017-11-29T09:56:46 < dongs> whats the common?
2017-11-29T09:56:47 < stvn> hell yeah
2017-11-29T09:56:52 < jpa-> common is C
2017-11-29T09:56:59 < dongs> isnt that click?
2017-11-29T09:57:01 < jpa-> dongs: center, left 1, left 2, right 1, right 2; so 5 positions
2017-11-29T09:57:11 < jpa-> no, click is Y, on the right side of diagram
2017-11-29T09:57:21 < jpa-> i think

2017-11-29T12:06:58 < kakimir> when program enters hardfault
2017-11-29T12:07:07 < kakimir> what is stored in R0?
2017-11-29T12:08:12 < kakimir> nothing particular
2017-11-29T12:11:14 < kakimir> what does TST r0, r1 do? it's a compare instruction
2017-11-29T12:12:30 < zyp> "The TST instruction performs a bitwise AND operation on the value in Rn and the value of Operand2. This is the same as an ANDS instruction, except that the result is discarded."
2017-11-29T12:12:52 < zyp> it's analogous to how a CMP is usually a SUB that discards the result
2017-11-29T12:12:59 < kakimir> why does this asm code copy LR first to r1 and then TST it?
2017-11-29T12:13:22 < kakimir> instead of directly TST r0, LR
2017-11-29T12:13:25 < zyp> probably because LR is not a valid Operand2
2017-11-29T12:13:32 < kakimir> okay
2017-11-29T12:13:47 < kakimir> it can access like 8 registers?
2017-11-29T12:13:54 < zyp> I don't know if this is the case here, but a bunch of thumb instructions can only target like half of the registers
2017-11-29T12:14:00 < kakimir> yes

2017-11-29T12:14:08 < kakimir> that is what I assumed
2017-11-29T12:14:17 < zyp> yes
2017-11-29T12:14:18 < zyp> The following form of the TST instruction is available in Thumb code, and is a 16-bit instruction:
2017-11-29T12:14:21 < zyp> TST Rn, Rm
2017-11-29T12:14:23 < zyp> Rn and Rm must both be Lo registers.
2017-11-29T12:14:40 < zyp> Lo is first half or something
2017-11-29T12:14:51 < zyp> and LR is in the second half
2017-11-29T12:15:55 < kakimir> makes sense
2017-11-29T12:16:21 < kakimir> http://www.support.code-red-tech.com/CodeRedWiki/DebugHardFault this is what I'm decoding

2017-11-29T12:18:31 < zyp> or just curious?
2017-11-29T12:19:14 < zyp> anyway, that ASM reads obvious to me

2017-11-29T12:20:23 < zyp> it's checking bit 2 in EXC_RETURN (which is stored in LR) to see if the interrupted frame is stored on MSP or PSP, then passing the relevant stack pointer as argument to HardFault_HandlerC
2017-11-29T12:21:24 < zyp> ref. http://infocenter.arm.com/help/topic/com.arm.doc.dui0552a/Babefdjc.html#BABDBEII for EXC_RETURN values
2017-11-29T12:21:37 < kakimir> oh LR is used sto store EXC_RETURN
2017-11-29T12:21:54 < kakimir> that is like the question I had
2017-11-29T12:22:02 < zyp> yes, EXC_RETURN is the magic that lets ISRs use the same ABI as standard function calls
2017-11-29T12:22:41 < zyp> the normal function ABI passes the return address in LR, so when a function wants to return, it just jumps to LR
2017-11-29T12:22:44 < zyp> i.e. BX LR
2017-11-29T12:23:51 < zyp> when an interrupt happens, a lot more shit is pushed onto the stack, and must be popped during the return, so instead of putting the return address in LR, an EXC_RETURN value is passed
2017-11-29T12:24:53 < zyp> they are not valid addresses for execution, so when you try jumping to EXC_RETURN, the cpu starts the ISR return procedure and pops all the stuff it stored from stack, including the real return address
2017-11-29T12:25:19 < kakimir> oh
2017-11-29T12:25:38 < kakimir> it utilizes like hidden registers?
2017-11-29T12:25:51 < zyp> no, there's no hidden registers
2017-11-29T12:26:04 < zyp> anyway, are you familiar with the function ABI?
2017-11-29T12:26:13 < zyp> caller and callee-save registers?
2017-11-29T12:26:46 < kakimir> vaguely
2017-11-29T12:27:08 < zyp> essentially, the ABI specifies some registers as caller-save and some registers as callee-save
2017-11-29T12:27:43 < zyp> the callee-save must be preserved by a called function so that they hold the same value when returning
2017-11-29T12:28:01 < kakimir> yes
2017-11-29T12:28:10 < kakimir> yes
2017-11-29T12:28:12 < zyp> caller-save registers can be overwritten whenever, so that the caller must save them before calling if it wants to keep the values
2017-11-29T12:28:30 < zyp> this is fine for normal functions
2017-11-29T12:28:53 < zyp> but ISRs can be called at any time, which means that all registers must be preserved
2017-11-29T12:29:24 < kakimir> why MRS is called copy from coprosessor register?
2017-11-29T12:29:28 < zyp> older architectures do this by giving ISRs a special ABI that makes all registers callee-save
2017-11-29T12:29:48 < zyp> legacy, probably
2017-11-29T12:30:12 < zyp> copy from a non-core register, I'd say
2017-11-29T12:30:19 < zyp> or special register
2017-11-29T12:30:49 < zyp> so anyway
2017-11-29T12:31:13 < zyp> cortex-m has EABI-compliant ISRs because the hardware saves all caller-save registers before calling the ISR
2017-11-29T12:31:46 < zyp> and EXC_RETURN returns control to the hardware that restores all caller-save registers again
2017-11-29T12:32:44 < zyp> the exact EXC_RETURN value contains whether they were stored on MSP or PSP and whether cpu was in thread or handler mode
2017-11-29T12:33:13 < zyp> so when your hardfault handler wants to look at the stack, it needs to check whether it should look on MSP or PSP
2017-11-29T12:34:52 < kakimir> yes
2017-11-29T12:35:03 < kakimir> I think I understood
2017-11-29T12:35:35 < kakimir> it's a fixed functionality of ISR implementation that looks for MSP or PSP to restore shiet

2017-11-29T12:36:22 < zyp> do you understand the relationship between MSP and PSP?
2017-11-29T12:36:35 < zyp> and why there's not just a single SP?
2017-11-29T12:36:44 < kakimir> not clearly
2017-11-29T12:36:51 < kakimir> it hs to do with threads
2017-11-29T12:37:03 < zyp> yes
2017-11-29T12:37:11 < zyp> are you familiar with how context switching works?
2017-11-29T12:38:33 < zyp> when switching between two threads, all the state (i.e. register contents) of the old thread needs to be stored, and the state of the new thread needs to be loaded
2017-11-29T12:39:28 < zyp> each thread has its own stack, so you can just push everything onto it, then switch stacks, then pop everything from the new stack

2017-11-29T12:39:42 < zyp> that's what a basic context switch does
2017-11-29T12:39:45 < kakimir> ÿes
2017-11-29T12:40:17 < kakimir> so PSP points to current thread stack
2017-11-29T12:40:28 < zyp> out of reset, stm32 starts with SP = MSP, and if you like, you can forget all about PSP and only use MSP
2017-11-29T12:40:36 < zyp> that's what I'm currently doing in laks

2017-11-29T12:42:38 < zyp> the question is why you wouldn't want to do that
2017-11-29T12:43:41 < kakimir> https://github.com/PetteriAimonen/QuadPawn/blob/master/Runtime/debug.c#L118 okay I think that answers the question why jpacode has only copy of msp
2017-11-29T12:44:05 < zyp> yes
2017-11-29T12:44:23 < zyp> now, imagine you have three tasks, say they each need 1k of stack
2017-11-29T12:44:58 < kakimir> okay
2017-11-29T12:45:13 < zyp> but then you also have an ISR that does some operation that needs 1k of stack
2017-11-29T12:46:09 < zyp> since the ISR can happen regardless of which thread is active, all three of those threads needs a stack big enough to accomodate the ISR
2017-11-29T12:46:36 < zyp> so you'll need 6k reserved to stacks in total
2017-11-29T12:46:47 < kakimir> yes
2017-11-29T12:47:35 < zyp> ISRs always use MSP, for threads you can choose whether to use MSP or PSP
2017-11-29T12:48:09 < zyp> if you use PSP for threads, you would need to keep MSP pointing to a separate stack for ISRs
2017-11-29T12:48:25 < kakimir> oh
2017-11-29T12:48:44 < zyp> in that case, each thread stack would only need to be 1k, and then you would have a separate 1k stack for ISRs
2017-11-29T12:48:53 < zyp> with reduces your memory need to 4k
2017-11-29T12:48:57 < kakimir> so why there is PSP at all?
2017-11-29T12:49:27 < kakimir> I mean why there is PSP implemented if using only MSP is better
2017-11-29T12:49:36 < karlp> he literally just said
2017-11-29T12:49:49 < zyp> so the thread can use SP = PSP and hardware can automatically switch to MSP when calling an ISR
2017-11-29T12:50:05 < zyp> and the EXC_RETURN then switches back to PSP automatically again
2017-11-29T12:50:52 < zyp> to summarize: using only MSP gives simpler code, but in the example would require 6k of memory reserved for stacks
2017-11-29T12:51:27 < zyp> using both MSP and PSP adds complexity to context switching and fault analysis but reduces memory need to 4k

2017-11-29T12:52:45 < zyp> in a singlethreaded firmware, there's no benefit from using PSP at all
2017-11-29T12:52:59 < zyp> which I suspect jpa's firmware is
2017-11-29T12:53:22 < kakimir> okay
2017-11-29T12:53:45 < kakimir> I got it wrong way around I thought using PSP had only downsides
2017-11-29T12:53:53 < zyp> no
2017-11-29T12:53:59 < kakimir> so it reduces ram usage
2017-11-29T12:54:17 < zyp> using PSP means you don't have to reserve space for ISRs on every thread stack
2017-11-29T12:54:28 < kakimir> also is there safety aspects when every process have own stack?
2017-11-29T12:54:42 < zyp> if you have only one thread stack, you save nothing by keeping a separate interrupt stack
2017-11-29T12:54:49 < zyp> what do you mean?
2017-11-29T12:55:17 < zyp> every thread _needs_ its own stack to work, that's where all state is stored

2017-11-29T12:56:00 < kakimir> okay it's enought for the day
2017-11-29T12:56:06 < kakimir> thanks zyp
2017-11-29T12:56:16 < dongs> i should leave dickstarte office
2017-11-29T12:56:22 < zyp> and ISRs generally have unrestricted access to memory so they can shit on all the process stacks anyway
2017-11-29T12:56:39 < kakimir> yes
2017-11-29T12:57:09 < kakimir> how do you change this MSP / MSP+PSP behaivour?
2017-11-29T12:57:17 < zyp> I guess safety wise, having a separate interrupt stack means that even if a process overflows its stack and gets trapped by MPU or something, you can handle it and only kill that thread, not the entire firmware
2017-11-29T12:57:53 < zyp> rtos would handle it when you start the scheduler
2017-11-29T12:58:10 < kakimir> default is MSP + PSP mode?
2017-11-29T12:58:16 < zyp> no, default is MSP only
2017-11-29T12:58:38 < zyp> everything runs from MSP until firmware tells it differently
2017-11-29T12:59:04 < kakimir> I mean for rtos
2017-11-29T12:59:17 < zyp> exactly how it's done would depend on the RTOS
2017-11-29T12:59:38 < kakimir> sure I know that everything runs from MSP at the begin of firmware
2017-11-29T13:00:04 < kakimir> what should I google for zyp?

2017-11-29T13:33:27 < ReadErr> lol so i was paying for my vpn the other day
2017-11-29T13:33:34 < ReadErr> cost me 3$
2017-11-29T13:33:37 < ReadErr> to send 8$
2017-11-29T13:33:40 < dongs> uh huh
2017-11-29T13:33:41 < ReadErr> what a fcking scam
2017-11-29T13:33:48 < dongs> and how long did that $3 take to process the $8
2017-11-29T13:34:02 < dongs> thats too cheap
2017-11-29T13:34:10 < dongs> i tihnk its around 10 or something now to process such a small payment
2017-11-29T13:34:11 < ReadErr> lol even funnier story, ended up being like 5$ short in 1 wallet
2017-11-29T13:34:12 < dongs> to get it done quickly
2017-11-29T13:34:20 < ReadErr> so figured, ok, ill send 2x payments for the amount
2017-11-29T13:34:30 < ReadErr> gets the 1st one, then is like nah, not enough
2017-11-29T13:34:32 < ReadErr> CANCELLED
2017-11-29T13:34:39 < ReadErr> after i spent the 3 fuckin dollars
2017-11-29T13:34:44 < ReadErr> to send the extra
2017-11-29T13:36:13 < dongs> and somehow shitcoin is not a scam
2017-11-29T13:36:48 < ReadErr> you know the best investment in it now?
2017-11-29T13:36:53 < ReadErr> exploitation
2017-11-29T13:36:58 < ReadErr> take the machine down
2017-11-29T13:37:19 < ReadErr> you can manipulate the price with ddos etc
2017-11-29T13:39:17 < dongs> gross.
2017-11-29T13:40:11 < ReadErr> whats crazy is the entire thing can collapse with 1 bug too
2017-11-29T13:40:27 < ReadErr> n vs n+1 array size, something dumb
2017-11-29T13:40:30 < ReadErr> is gonna do it
2017-11-29T13:40:57 < ReadErr> theres actually no way to profit on bitcoin falling in price
2017-11-29T13:41:12 < ReadErr> very very few places let you short
2017-11-29T13:42:07 < ReadErr> aww ya chinablet shipped maybe be here by fri
2017-11-29T13:47:12 < dongs> haha you wish
2017-11-29T13:48:56 < ReadErr> dhl
2017-11-29T13:49:03 < ReadErr> could be here tomorrow

2017-11-29T13:58:09 < zyp> any exchange that does margin trading will let you short

2017-11-29T13:59:46 < zyp> haha
2017-11-29T13:59:58 < ReadErr> and getting margin enabled requires some heavy paperwork or lying
2017-11-29T14:00:05 < zyp> bullshit
2017-11-29T14:00:11 < ReadErr> to do it 'legally'
2017-11-29T14:00:17 < ReadErr> have you read the gdax requirements ?
2017-11-29T14:00:45 < BrainDamage> i want a keyboard with builtin speakers so i can make it as obnoxious as possible on keypresses

2017-11-29T14:01:43 < ReadErr> haha
2017-11-29T14:01:50 < ReadErr> gdax might have margins turned off right now too
2017-11-29T14:02:28 < zyp> so it says

2017-11-29T14:04:32 < ReadErr> which would you fall under?
2017-11-29T14:04:44 < ReadErr> since you know, we do thangs legally
2017-11-29T14:04:46 < ReadErr> n all
2017-11-29T14:05:08 < zyp> neither, I guess, I'm not a US citizen, so your laws aren't very relevant to me
2017-11-29T14:06:11 < zyp> gdax doesn't even let me trade USD, just EUR
2017-11-29T14:06:39 < zyp> "BTC/USD trading is not yet available in your region."
2017-11-29T14:06:52 < ReadErr> what other exchanges do margin ?
2017-11-29T14:07:00 < ReadErr> from crypto to fiat
2017-11-29T14:07:27 < ReadErr> the fact they can just turn the shit off, is fucked too
2017-11-29T14:07:35 < zyp> does bitmex apply?
2017-11-29T14:07:54 < dongs> why are you fags even talking about buttcoin anyway?
2017-11-29T14:08:06 < dongs> havent you heard? you lose money the second buttcoin is inyour head, before you even type about ti
2017-11-29T14:08:09 < dongs> it
2017-11-29T14:08:14 < zyp> haha
2017-11-29T14:08:46 < zyp> only way I've lost money on BTC is because I didn't keep the ones I dicked around with in 2011
2017-11-29T14:08:51 < zyp> they'd be worth a house today
2017-11-29T14:09:18 < dongs> but thats the thing
2017-11-29T14:09:22 < dongs> you wouldnt be able to turn it into a house
2017-11-29T14:09:34 < zyp> sure I would
2017-11-29T14:09:36 < dongs> you woudlnt be able to do shti with it other than MAYBE sell it to another retard for something
2017-11-29T14:09:56 < ReadErr> zyp: i dont see how that would work
2017-11-29T14:10:07 < ReadErr> because they dont let you deposit or w/d anything but shitcoin
2017-11-29T14:10:16 < ReadErr> or thats what the FAQ says
2017-11-29T14:11:53 < zyp> dongs, I exchanged like $5k worth of bitcoin a week or two ago, bought in one currency, sold in another, avoided a ton of exchange fees and shit
2017-11-29T14:11:58 < zyp> way cheaper than using paypal for the same
2017-11-29T14:12:14 < ReadErr> zyp: i tried to send 8$
2017-11-29T14:12:17 < ReadErr> it cost me 3$
2017-11-29T14:12:26 < zyp> then you're using a retarded wallet
2017-11-29T14:12:34 < ReadErr> no, the fees where all fucked
2017-11-29T14:12:38 < ReadErr> bitpay
2017-11-29T14:12:42 < ReadErr> time
2017-11-29T14:13:01 < zyp> exactly, your wallet is what decides the fees
2017-11-29T14:13:12 < dongs> <zyp> i bought $5k worth of weed last week
2017-11-29T14:13:17 < dongs> ^ this is what i read it as
2017-11-29T14:13:29 < ReadErr> https://usercontent.irccloud-cdn.com/file/S8PIe5Ey/shitcoin.png
2017-11-29T14:13:38 < ReadErr> its just a blockchain.something wallet
2017-11-29T14:13:41 < zyp> dongs, no, I got paid, not opposite
2017-11-29T14:13:58 < dongs> so how did you turn it into 5k of real money?
2017-11-29T14:14:04 < dongs> without giving up MUH PRIVACY
2017-11-29T14:14:26 < ReadErr> you can use localshitcoinexchange
2017-11-29T14:14:34 < ReadErr> but you may, or may not get raped and murdered and robbed
2017-11-29T14:14:49 < dongs> theres no way shitcoin exchange rates are better than real bank transfer using real money
2017-11-29T14:15:04 < dongs> and if youre gonna scan your ID into a shitcoin.comthats gonna get hacked tomororw, you might as well stick to banks
2017-11-29T14:15:06 < ReadErr> oh no, its not
2017-11-29T14:15:17 < ReadErr> yea now everyone has 'know ur customer' here
2017-11-29T14:15:23 < ReadErr> so they gotta papertrail all that shit
2017-11-29T14:16:58 < zyp> dongs, idk, what rates does your bank get you on foreign exchange?
2017-11-29T14:17:37 < dongs> zyp, whatever google.com tells me an surely at only $5k the difference between like 0.01$ in exchange is gonna be like 50cents
2017-11-29T14:19:11 < zyp> idk, I think my bank does like 1.75% on currency conversion
2017-11-29T14:20:15 < zyp> paypal is like 3-4%
2017-11-29T14:20:20 < dongs> blame the NO(R)Ks
2017-11-29T14:20:44 < dongs> buying $5k of shitcoin an it dropping 500% tomorrow: priceless
2017-11-29T14:20:59 < dongs> or -500% or whateer
2017-11-29T14:21:14 < zyp> didn't keep those, just bought and sold
2017-11-29T14:22:26 < BrainDamage> if you use as a trade medium you want to cash out asap, you hold bitcoin only if you're speculating or you're a crazy that it might work as currency
2017-11-29T14:23:06 < dongs> http://www.alps.com/prod/info/E/HTML/MultiControl/Switch/SLLB/SLLB120300.html wat the hell
2017-11-29T14:23:24 < dongs> the drawing here is same as on chink site
2017-11-29T14:23:26 < dongs> for schematic
2017-11-29T14:23:28 < dongs> makes no fucking sense
2017-11-29T14:26:32 < dongs> i mean i think E is common and then all the other pins short against it
2017-11-29T14:26:43 < dongs> but what the fuck does that drawing even mean
2017-11-29T14:28:21 < dongs> "ground terminal" in alps drawing
2017-11-29T14:28:33 < aandrew> dongs: what are you autisming about
2017-11-29T14:28:39 < dongs> that part

2017-11-29T14:30:29 < aandrew> if I understand it, both CCW and CW have two positions
2017-11-29T14:31:07 < aandrew> for CCW, halfway is 1+C and full is 1+2+C
2017-11-29T14:31:17 < BrainDamage> yup
2017-11-29T14:31:19 < aandrew> same thing for CW but 4+C and 3+4+C
2017-11-29T14:31:31 < aandrew> and push is T+C
2017-11-29T14:31:41 < aandrew> but to draw a schematic symbol that makes sense... good luck
2017-11-29T14:31:49 * Laurenceb read that as CWC
2017-11-29T14:31:57 < Laurenceb> too much internets 4 me
2017-11-29T14:31:57 < dongs> what about the ground pad then
2017-11-29T14:31:58 < aandrew> CWC?
2017-11-29T14:32:01 < dongs> why is C repeated twice
2017-11-29T14:32:08 < aandrew> probably two pins for it
2017-11-29T14:32:10 < karlp> and no-one but you gives a shit about what stupid acronyms yhou care about lolrence
2017-11-29T14:32:16 < karlp> counter-clockwise
2017-11-29T14:32:23 < Laurenceb> https://sonichu.com/cwcki/Autism
2017-11-29T14:33:07 < aandrew> I think C is ground
2017-11-29T14:33:07 < BrainDamage> the ground I'd assume it's the chassis, but not electrically connected to any pin
2017-11-29T14:33:29 < dongs> aandrew: theres also "ground pad" on the left
2017-11-29T14:33:37 < aandrew> yes I see that
2017-11-29T14:33:50 < BrainDamage> just short it to c anyway
2017-11-29T14:33:53 < aandrew> it looks like "ground terminal" and "C" on the "face" are both the same metal
2017-11-29T14:34:10 < Laurenceb> http://knowyourmeme.com/memes/sonichu
2017-11-29T14:35:32 < aandrew> on the land dimensions you have the 6 pads on the bottom (1 2 T 3 4 C) but then ther eare two just above them (vertically overlapping the pins in fact) which are probably chassis ground, then two more above those and "rotated" 90 degrees, left one is labelled "ground terminal" and right is C
2017-11-29T14:35:42 < aandrew> but those last 4 I think are all chassis connection
2017-11-29T14:35:50 < aandrew> that's my guess anyway
2017-11-29T14:36:08 < aandrew> dongs: order a couple from digik... oh wait, you're banned lol
2017-11-29T14:36:22 < zyp> ReadErr, and re: bitmex, yes, they do BTC only, that doesn't prevent you from shorting BTC
2017-11-29T14:37:01 < ReadErr> if the bottom falls out
2017-11-29T14:37:05 < ReadErr> you cant get ur money
2017-11-29T14:37:53 < BrainDamage> assume that people aren't that stupid to do mtgox2
2017-11-29T14:38:07 < dongs> aandrew: i can get clones from chiangirl for super cheap
2017-11-29T14:38:09 < Laurenceb> yeah but you could start running it
2017-11-29T14:38:15 < Laurenceb> then steal the moneys
2017-11-29T14:38:16 < dongs> thats how i found the alps
2017-11-29T14:38:17 < BrainDamage> wait, what, how can you get banned from digikey
2017-11-29T14:38:18 < aandrew> how is bitmex any different from mtgox in terms of that happenning
2017-11-29T14:38:21 < dongs> it was chinaclone of something else
2017-11-29T14:38:22 < ReadErr> you still need a willing party to convert the btc to actual currency
2017-11-29T14:38:29 < ReadErr> someone has to buy it
2017-11-29T14:38:34 < Laurenceb> BrainDamage: thats nothing, I'm banned from 4chan
2017-11-29T14:38:39 < dongs> someone has to be dumb enough to buy it
2017-11-29T14:38:46 < aandrew> Laurenceb: yep that's my concern with all this crytpo stuff
2017-11-29T14:38:59 < aandrew> it is lovely on paper but until you can actually cash out your millions... it's all pretend
2017-11-29T14:39:57 < ReadErr> so my point still stands, theres no proper shorting easily accessible
2017-11-29T14:40:06 < ReadErr> no natural way for it to go down in price
2017-11-29T14:40:12 < dongs> OK
2017-11-29T14:40:13 < dongs> so
2017-11-29T14:40:15 < ReadErr> without people losing money
2017-11-29T14:40:21 < dongs> left pad = gnd on that thing, just body/case probably
2017-11-29T14:40:23 < BrainDamage> if you want to do an equivalent schematic, you could do one with a 4 pole 5 throw switch
2017-11-29T14:40:30 < BrainDamage> but it's going to look ugly
2017-11-29T14:40:34 < dongs> and then C is common, and 1/2/3/4 click to it from knob, and T clicks t oit from push
2017-11-29T14:40:37 < dongs> right?
2017-11-29T14:40:43 < dongs> and C is duplicated on the other side for reasons
2017-11-29T14:41:08 < zyp> ReadErr, how about the CME derivates? I think they launch next week or something
2017-11-29T14:41:19 < BrainDamage> yes, remember tought that in the extreme positions, you won't get 'just' 1 or 2
2017-11-29T14:41:23 < BrainDamage> but BOTH 1 and 2
2017-11-29T14:41:32 < ReadErr> zyp: not looked at that
2017-11-29T14:41:39 < dongs> BrainDamage: yeah ,thats clear fromthe drawing
2017-11-29T14:41:54 < aandrew> I'd probably draw it as a selector switch with 1 and 4 "closest" to the selector and 2 and 3 farther from them, witht he selector itself as "C"
2017-11-29T14:42:12 < dongs> ya gonna ghetto somethin up
2017-11-29T14:42:15 < aandrew> with a pushbutton kind of symbol with one leg tied to C and the other called T
2017-11-29T14:42:18 < aandrew> hang on let me sketch
2017-11-29T14:42:20 < aandrew> no laughing
2017-11-29T14:42:33 < dongs> no worries, it will likely be better what i can come up with
2017-11-29T14:43:20 < BrainDamage> 1 pole 4 throw will work, but it won't show up the shorting of 1&2 and 3&4

2017-11-29T14:47:34 < dongs> thanks
2017-11-29T14:48:03 < aandrew> I'd label one side CW and the other CCW but otherwise I think that's how I'd draw it
2017-11-29T14:48:16 < dongs> right
2017-11-29T14:48:23 < aandrew> maybe draw some dotted line arc around the penis to try to indicate that it's a rocker
2017-11-29T14:54:14 < aandrew> https://imgur.com/r7KNtX1
2017-11-29T14:54:37 < aandrew> if you wanted to get fancy you could arrange the contacts in an arc instead of a line but whatev
2017-11-29T14:55:11 < aandrew> pretty sure that the chassis and C are all the same so you actually have 5 C pins
2017-11-29T14:55:17 < aandrew> but without one in hand it's hard to tell for sure

2017-11-29T15:02:01 < dongs> like the one in line

2017-11-29T17:38:02 < jadew> I was planning to make a logic analyzer a couple of years ago and as it happens I'm building one now (but just for me, to help me with another project)
2017-11-29T17:38:16 < jadew> I might consider making it into a product

2017-11-29T17:39:01 < jadew> this thing has 64 channels
2017-11-29T17:40:55 < jadew> I could probably do $150 - $200

2017-11-29T17:42:26 < jadew> I already have a working one on my bench
2017-11-29T17:42:27 < aandrew> for everyone else, a $3 FX2LP + saleae or sigrok will be more than enough and you'll never sell it
2017-11-29T17:42:41 < aandrew> well let's look at it
2017-11-29T17:42:47 < aandrew> what have you got for input proteection?
2017-11-29T17:42:55 < aandrew> what's your minimum pulse spec?
2017-11-29T17:43:04 < jadew> I didn't do that part, just resistors
2017-11-29T17:43:05 < aandrew> how is your timing accuracy across all 64 channels?
2017-11-29T17:43:18 < jadew> timing accuracy wouldn't be a problem
2017-11-29T17:43:45 < aandrew> input protection tends to vary with PVT. you need a way to characterize and calibrate it, which drives up your mfg costs
2017-11-29T17:44:12 < aandrew> capacitance will skew timing to some degree, but depending on your accuracy spec it might/probably not matter
2017-11-29T17:44:35 < jadew> the timing can be fixed in one revision
2017-11-29T17:44:59 < jadew> you make a jig to test it and tell you how much you're off on each input
2017-11-29T17:45:12 < jadew> then you fix the trace length accordingly
2017-11-29T17:45:57 < aandrew> my point is that all these things eat into yoru profit, and if $200 is your target your COGS better be under $100

2017-11-29T18:20:31 < zyp> okay, 100Msps is too slow
2017-11-29T18:20:45 < jadew> yeah, I think I can get 400-500 Msps
2017-11-29T18:20:57 < jadew> last time I considered it (a couple of years ago) that was the target
2017-11-29T18:21:02 < karlp> yeah, 100 is more than enough for basic use, not enough for "serious" use
2017-11-29T18:21:08 < jadew> might be able to do higher, but then I guess I'd need better connectors
2017-11-29T18:21:18 < karlp> 24Mhz on the cheapest fx2 devices is amateur only stuff
2017-11-29T18:21:57 < zyp> when I were looking around at LAs, I wanted something that could capture PATA
2017-11-29T18:22:44 < qyx> more like pita
2017-11-29T18:22:46 < jadew> what's the clock on that thing?
2017-11-29T18:22:51 < qyx> hm, that would be handy for my stm32 + CF card
2017-11-29T18:23:22 * invzim got saleae ORIGINAL
2017-11-29T18:23:27 < zyp> dunno what standard I'd be looking at, but IIRC PATA is up to 133MHz
2017-11-29T18:23:48 < aandrew> I have a chinese knockoff saleae and an FX2LP devkit. covers pretty much all I need to do with LA
2017-11-29T18:24:20 < invzim> tricky part, I learned the hard way, is the probes
2017-11-29T18:24:23 < jadew> zyp, would you have paid ~$200 for it?
2017-11-29T18:24:40 < jadew> invzim, how so?
2017-11-29T18:24:49 < jadew> you mean the clips quality or their bandwidth?
2017-11-29T18:24:54 < zyp> jadew, for something decent? sure
2017-11-29T18:24:55 < invzim> both
2017-11-29T18:25:17 < jadew> invzim, yeah, I know and I've been thinking about their bandwidth
2017-11-29T18:25:21 < zyp> I was considering a $1400 one, or whatever it was, just didn't have money to throw at it
2017-11-29T18:25:21 < invzim> dupont cables to a header just doesn't cut it
2017-11-29T18:25:24 < jadew> with shitty probes you'll get very low bandwidth
2017-11-29T18:25:39 < jadew> zyp, that's good to know
2017-11-29T18:25:52 < jadew> thanks
2017-11-29T18:26:13 < invzim> making high quality high impedance stuff turns out to be a bit of an art, that the scope guys have been working on for ages
2017-11-29T18:26:14 < daey> aandrew: there was/is a cool fpga based logic analyzer that also can do crude analog measurements. sadly the project died pretty much
2017-11-29T18:26:18 < zyp> hmm
2017-11-29T18:26:49 < daey> some chinese sold it 2 years ago iirc. but the software sucked from what i was able to figure out
2017-11-29T18:26:51 < jadew> invzim, yeah, I've seen some nice agilent probes, but I don't think they'd be easy to source/cheap
2017-11-29T18:27:11 < invzim> not sure where I saw it, but I think some vendors are using HDMI cables for it?
2017-11-29T18:27:37 < invzim> what do you need to analyze/capture?
2017-11-29T18:27:42 < jadew> invzim, interesting idea
2017-11-29T18:28:30 < jadew> me? I'm just reverse engineering something and I have to sniff 40 signals
2017-11-29T18:29:22 < invzim> that's a lot :)

2017-11-29T20:56:59 < kakimir> wait.. usb dongles appear as wlan device so it falls under control of that crimped interface
2017-11-29T20:57:32 < kakimir> but I need like something that emulates ethernet but is actually wlan
2017-11-29T20:58:49 < kakimir> maybe just buy.. used wlan router
2017-11-29T20:59:14 < qyx> every time I touch scons I face some new surprises

2017-11-29T20:59:51 < qyx> kakimir: wat
2017-11-29T21:00:39 < qyx> yes you can setup your wlan device as a client and use it as a wan port
2017-11-29T21:01:28 < kakimir> I said isp crimped box
2017-11-29T21:01:34 < kakimir> there is no client mode
2017-11-29T21:01:50 < qyx> then buy a proper device for 25€
2017-11-29T21:02:07 < qyx> or reflash it
2017-11-29T21:02:08 < kakimir> I think I buy something really cheap to connect to wan port
2017-11-29T21:02:34 < qyx> open the list of openwrt supported devices and select one
2017-11-29T21:02:39 < qyx> or buy a 30€ mikrotik
2017-11-29T21:02:46 < qyx> and don't mess with openwrt

2017-11-29T21:03:08 < qyx> but beware that they have different licensing levels, L3 cannot do wifi AP
2017-11-29T21:05:30 < qyx> sometimes you seem to be overly rethinking your problems and making much needless work
2017-11-29T21:08:49 < kakimir> I buy some old surefire b/g router
2017-11-29T21:11:04 < qyx> what speeds are you expecting with an old b/g router?
2017-11-29T21:13:30 < kakimir> 54
2017-11-29T21:13:45 < kakimir> hopefully at least in one direction
2017-11-29T21:14:29 < qyx> haha
2017-11-29T21:14:39 < qyx> lold
2017-11-29T21:15:24 < kakimir> I got something like 30/30 without the panel antenna I installed to that crimped box today
2017-11-29T21:15:44 < qyx> for sure you cannot get 30/30 with a g router
2017-11-29T21:16:00 < qyx> one direction only, indoors maybe
2017-11-29T21:16:35 < qyx> prepare for 10-15mbit one direction in ideal conditions outdoors in the g band
2017-11-29T21:16:55 < kakimir> hmm
2017-11-29T21:17:05 < kakimir> wait I got like 20/20
2017-11-29T21:17:09 < kakimir> in speedtest
2017-11-29T21:17:22 < qyx> but speedtest is not receiving and transmitting data simultaneously
2017-11-29T21:17:23 < kakimir> so it wasn't full duplex
2017-11-29T21:17:26 < kakimir> ye
2017-11-29T21:17:35 < kakimir> well that is not that important
2017-11-29T21:17:40 < qyx> fd would be like 5/5, 10/10 at most
2017-11-29T21:18:05 < kakimir> ye
2017-11-29T21:18:06 < qyx> and usually not symmetrical
2017-11-29T21:18:14 < kakimir> I noticed
2017-11-29T21:18:22 < kakimir> it likes to prefer sending
2017-11-29T21:18:26 < qyx> yes
2017-11-29T21:18:26 < kakimir> more
2017-11-29T21:18:41 < kakimir> just the wrong way around
2017-11-29T21:20:59 < kakimir> can I change that unbalanced situation between tx and rx?
2017-11-29T21:21:04 < kakimir> with software
2017-11-29T21:22:37 < kakimir> so if I get mid 20's speed what does that 54 then stand for?
2017-11-29T21:23:00 < qyx> yes, mikrotik has some proprietary 802.11 addons for that for example
2017-11-29T21:23:06 < qyx> polled mode and nstreme mode
2017-11-29T21:23:31 < qyx> which allows managing that csma/ca anarchy to some degree
2017-11-29T21:24:04 < qyx> 54mbit/s is maximum theoretical speed at the physical layer
2017-11-29T21:24:17 < qyx> with no protocol overhead, no collisions, no interference
2017-11-29T21:24:57 < kakimir> In practice, access points may not have an ideal implementation and may therefore not be able to achieve even 31.4 Mbit/s throughput with 1500 byte packets
2017-11-29T21:25:43 < qyx> switch to 5G, turbo mode with atheros cards (40MHz channel width, although not legal in all countries)
2017-11-29T21:25:53 < qyx> and two parallel links, one for tx, one for rx
2017-11-29T21:26:16 < qyx> nstreme2 over them and eoip or simular ethernet-level vpn over them
2017-11-29T21:26:24 < kakimir> if I even get 20mbps it's good enought
2017-11-29T21:26:25 < qyx> we used that to get stable links in bridged networks ^
2017-11-29T21:26:45 < kakimir> my standards come down
2017-11-29T21:27:34 < kakimir> I'm pretty much done with this project
2017-11-29T21:28:16 < kakimir> current connection is 8M/1M at the client side
2017-11-29T21:28:36 < kakimir> so getting +20M there would have critical effect
2017-11-29T21:28:58 < kakimir> and especially for uploads

2017-11-29T22:18:19 < kakimir> howe do they have kernel 10.0
2017-11-29T22:18:28 < kakimir> when I have only 9.0
2017-11-29T22:20:04 < kakimir> hey I can use lpc54018 config code for my lpc1517
2017-11-29T22:20:07 < karlp> what on earth would cause this sort of thing? https://zerobin.net/?33337be5409f0c52#kfvMa6NewlekhJPvh4KxsrDnaFl+6u0gwOxSjZAyIAE=
2017-11-29T22:20:20 < kakimir> it has similar if not totally symmetrical core stuff
2017-11-29T22:22:21 < kakimir> I see priobits are exactly what I thought were correct for lpc1517
2017-11-29T22:23:14 < karlp> I'm suspecting weird pointer mangling, and the only thing that changes between "working" code and "shit's busted in weird ways" is adding some variables to that internal structure
2017-11-29T22:23:38 < karlp> and it sitll actually works until I try loading them back in from eeprom, where I htink something gets confused by those sizeofs not being self consistent.
2017-11-29T22:25:06 < qyx> Laurenceb-level bug
2017-11-29T22:28:18 < karlp> yeah, kinda hair tearing
2017-11-29T22:30:29 < karlp> there's no way I can add 6 bytes and still just have things repacked and fit in the same thing.
2017-11-29T22:30:43 < karlp> it can't reorder4 things anyway, it can only add padding right?
2017-11-29T22:33:14 < karlp> adding 4x16bit vars instead of 3x16bit vars makes everything behave "as expected"
2017-11-29T22:33:33 < jpa-> if you have a uint64_t there, you could add up to 7 bytes and it might align the same
2017-11-29T22:33:34 < qyx> so you are making a struct with a configuration
2017-11-29T22:33:39 < qyx> saving it to the eeprom
2017-11-29T22:33:50 < qyx> and when you are reading it back, it reads incorrect values?
2017-11-29T22:34:03 < qyx> (if you reflashed the mcu between the reading and writing)
2017-11-29T22:34:35 < karlp> jpa-: the next variable in the parent struct is indeed a uint64
2017-11-29T22:35:10 < jpa-> yeah, alignment goes to the size of the variable, not to the machine word size
2017-11-29T22:35:36 < karlp> qyx: every portion I've looked at has loaded properly when i step through it, but the modbus library starts getting things mangled, so I'm presuming something gets mangled somewhere, but I'm not sure where it would have been

2017-11-29T23:27:41 < karlp> no, old branch works now too.
2017-11-29T23:27:46 < karlp> no fucking clue what happened

2017-11-29T23:27:57 < karlp> no, not really.
2017-11-29T23:28:29 < Getty> since I know C the word "fun" really got a new dimension ;)
2017-11-29T23:28:34 < karlp> I left it yesterday afternoon, said, "this is weird, I bet it goes away in the morning, whatever the fuck it is"
2017-11-29T23:30:13 < zyp> I spent a day making a simple ethernet bootloader gui utility at work
2017-11-29T23:31:32 < invzim> one day?
2017-11-29T23:32:15 < zyp> coworkers are heading off tomorrow to run some tests on a device, so they asked yesterday «what do we do if we need to upgrade the firmware?»
2017-11-29T23:32:52 < invzim> whatevere they're paying you, it should be more :)
2017-11-29T23:33:27 < zyp> and I'm like «uh, we have a bootloader now, but the host side script I hacked up is a mess that won't transfer well to another computer»
2017-11-29T23:34:34 < qyx> did you do a single click Qt gui thing?
2017-11-29T23:35:11 < zyp> so I started hacking up some simple gui that lets user open a specific ethernet interface and an elf file and write it
2017-11-29T23:35:32 < zyp> my bootloader protocol doesn't do addressing yet, so I didn't have to implement that
2017-11-29T23:35:55 < zyp> qyx, not sure what you mean by single click, but I used Qt, yes
2017-11-29T23:38:00 < zyp> when you start it it pops up a dialog with a list of network interfaces, after selecting one you get a window with «Open firmware file» and «Write firmware» buttons and a textbox that prints progress info
2017-11-29T23:38:26 < zyp> ended up quite nice
2017-11-29T23:40:07 < zyp> got most of the stuff working before I left yesterday, did the last polish this morning by adding timeouts and retries so it doesn't hang when it can't find a device or takes too long to negotiate ethernet again after a reset
2017-11-29T23:43:20 < zyp> https://paste.jvnv.net/view/JrgDM <- coroutines are a pretty damn neat way of handling sequences, by the way
2017-11-29T23:45:14 < qyx> looks simple
2017-11-29T23:46:43 < zyp> send_cmd() doesn't return until it gets an ack from the device (or it times out)
2017-11-29T23:47:41 < zyp> and the async stuff avoids locking up the gui while it's waiting, without adding multithreading complexity or callbacks or whatever
2017-11-29T23:49:51 < zyp> invzim, idk, I feel like I do enough slacking off as well :p
2017-11-29T23:51:47 < zyp> and most of the non-gui-stuff is just refactored from the mess I had before
2017-11-29T23:53:51 < zyp> spent some time looking into .exe-packers for python since py2exe apparently isn't maintained anymore and doesn't work with 3.6
2017-11-29T23:55:15 < zyp> turns out that pyinstaller works better than py2exe ever did

2017-11-30T01:28:17 < upgrdman> dynamically types languages induce much rage
2017-11-30T01:28:18 < ohsix> like a const-type
2017-11-30T01:28:28 < ohsix> python has range types tho, it's cool
2017-11-30T01:28:29 < karlp> better use hungarian notation
2017-11-30T01:30:19 < zyp> upgrdman, short answer: no
2017-11-30T01:30:38 < zyp> depending on what you want to actually achieve, there might be solutions
2017-11-30T01:31:14 < ohsix> you could create a class with methods that abort if you try and change the type
2017-11-30T01:31:36 < ohsix> huh http://mypy-lang.org/
2017-11-30T01:31:43 < zyp> upgrdman, there's type hints though: https://docs.python.org/3/library/typing.html#module-typing
2017-11-30T01:31:45 < karlp> there's a pep for adding annotations to help tooling shit
2017-11-30T01:31:49 < karlp> yeah, that :)
2017-11-30T01:31:57 < zyp> but I'm not sure what they are useful for, apart from static analysis
2017-11-30T01:32:22 < ohsix> NewType
2017-11-30T01:32:42 < upgrdman> god damn. wtf couldnt they make it easy to force something to always be an integer
2017-11-30T01:32:46 < zyp> ohsix, very gundam
2017-11-30T01:33:03 < zyp> upgrdman, just cast it to an integer?
2017-11-30T01:33:11 < upgrdman> instead i have to int(cocks)
2017-11-30T01:33:27 < zyp> it's not like int i = 1 is any shorter than i = int(1)
2017-11-30T01:33:50 < upgrdman> zyp, ya but then i += 0.5 will result in a floaty
2017-11-30T01:33:57 < kakimir> duckin freertos back on track
2017-11-30T01:34:00 < upgrdman> instead of an error or another int
2017-11-30T01:34:15 < upgrdman> makes understanding old code such a pain
2017-11-30T01:35:27 < upgrdman> so ya, karl's comment on hungarian shitz is prolly the cleanest way to unfuck this
2017-11-30T01:36:03 < ohsix> upgrdman: what do you want it to do when it changes type?
2017-11-30T01:36:10 < ohsix> er
2017-11-30T01:36:13 < ohsix> heh k, i see
2017-11-30T01:36:21 < upgrdman> ohsix, ya exactly. i DONT want it to change type
2017-11-30T01:36:40 < ohsix> you could check the type after, or cast them so the type conversion doesn't happen
2017-11-30T01:36:40 < upgrdman> if i have an array index, and im doing math on it, i want int math
2017-11-30T01:36:41 < upgrdman> etc
2017-11-30T01:37:00 < ohsix> use numpy :p
2017-11-30T01:37:18 < upgrdman> not sure if blender supports numpy
2017-11-30T01:37:36 < ohsix> it does if you import it, hehe
2017-11-30T01:37:41 < upgrdman> and im just use python to play with scripting animation and maybe a lil game logic for robot prototyping
2017-11-30T01:38:06 < ohsix> well numpy isn't going to help there
2017-11-30T01:38:08 < upgrdman> also, fuck, i miss having a proper ide when writing code. where my god damn ctrl-space to autocomplete :(
2017-11-30T01:38:37 < upgrdman> and alt-shift-r to refactor :(
2017-11-30T01:38:40 < ohsix> typing seems to have all the stuff you'd want to create a type system
2017-11-30T01:39:17 < ohsix> but you can also never use the result of something without int()
2017-11-30T01:39:30 < ohsix> probably want floor or something instead to better match intent if there's going to be a remainder
2017-11-30T01:40:12 < ohsix> i love irc for those types of questions
2017-11-30T01:44:02 < karlp> wooee, my problem is back again!
2017-11-30T01:45:03 < ohsix> cython has a thing too http://cython.readthedocs.io/en/latest/src/quickstart/cythonize.html though this is something that blender probably can't do
2017-11-30T01:49:49 < ohsix> pep 0484 has bound tying and a bunch of stuff too
2017-11-30T02:02:46 < kakimir> how are parameters passed to function?

2017-11-30T02:10:53 < kakimir> but when I read uptime variable in uptime command
2017-11-30T02:10:58 < kakimir> hardfault
2017-11-30T02:11:09 < kakimir> also uptime_ms variable is 0
2017-11-30T02:13:31 < kakimir> okay I forgot delay
2017-11-30T02:13:39 < kakimir> why is it 0 when there is no delay
2017-11-30T02:13:52 < kakimir> and when there is delay I got to 3000
2017-11-30T02:14:23 < kakimir> lets make that uptime variable volatile?

2017-11-30T11:52:50 < dongs> global chatdown
2017-11-30T11:54:12 < MrMobius> who are you talking to dongs?
2017-11-30T11:54:17 < MrMobius> youre autisming
2017-11-30T11:54:24 < dongs> MrMobius: my point exactly
2017-11-30T11:54:26 < dongs> nobody is chatting
2017-11-30T11:54:39 < dongs> all i see is people joining/quitting
2017-11-30T11:54:49 < MrMobius> I started learning c#. we can chat about that
2017-11-30T11:54:54 < MrMobius> it is a steaming pile of shit so far
2017-11-30T11:55:02 < dongs> are you learning c# 1.0 or the newfag c# thats unreadable
2017-11-30T11:55:16 < MrMobius> the 2017 mindrape version
2017-11-30T11:55:20 < dongs> ur fukt
2017-11-30T11:55:26 < MrMobius> i noticed
2017-11-30T11:55:30 < dongs> really tho 1.0 isnt bad
2017-11-30T11:55:34 < dongs> but god damn the new shit they added
2017-11-30T11:55:38 < dongs> thankfully you dont need to use it
2017-11-30T11:56:00 < MrMobius> well there are so many ways to do thing that are not obvious just looking at them
2017-11-30T11:56:14 < MrMobius> i can adjust to foreach but they have like sql database shit directly in the code
2017-11-30T11:56:50 < dongs> linq shit can go away
2017-11-30T11:56:51 < MrMobius> also you can go nuts with the new keyword since who cares about memory
2017-11-30T11:56:57 < dongs> same goes with var, auto etc
2017-11-30T11:57:03 < MrMobius> ya

2017-11-30T11:58:12 < MrMobius> so after my shitty little program got to400mb of memory it crashed
2017-11-30T11:58:15 < MrMobius> nope
2017-11-30T11:58:23 < dongs> haha
2017-11-30T11:58:30 < dongs> there is .delete like thing anyway
2017-11-30T11:58:33 < dongs> the .DIspose()
2017-11-30T11:58:39 < dongs> if youre certain youre done wiht stuff
2017-11-30T11:58:41 < dongs> should probly use that
2017-11-30T11:59:00 < dongs> they say "usually" its not needed but when yhoure in cases like that i guess it works

2017-11-30T11:59:24 < MrMobius> ya there is that but i dont think it acually frees the memory until the gc runs
2017-11-30T11:59:31 < MrMobius> it just marks it as to be freed or something
2017-11-30T12:00:09 < MrMobius> you have to rely on your old friend DoEvents from visual basic 6.0 days

2017-11-30T13:25:36 < kakimir> btw why to use pvPortMalloc instead of malloc
2017-11-30T13:25:56 < kakimir> malloc in my library functions seem to work totally fine?
2017-11-30T13:30:01 < kakimir> dat bit pattern in ram has something to do with stack high watermarking?
2017-11-30T13:41:23 < qyx> freertos uses those portmalloc functions internally and you can too
2017-11-30T13:41:45 < qyx> then there are different memory managers in the ports directory
2017-11-30T13:41:49 < qyx> somewhere
2017-11-30T13:41:55 < qyx> you can choose one

2017-11-30T13:43:26 < jpa-> kakimir: they call it pvPortMalloc so that it can be redefined easier than libc's malloc
2017-11-30T13:43:41 < jpa-> but most of the time you'll want them to be the same function

2017-11-30T14:08:44 < karlp> but perhapsthat was unhelpful.
2017-11-30T14:08:49 < karlp> I've not no.
2017-11-30T14:12:23 < kakimir> it would suck if it wasn't supported
2017-11-30T14:12:54 < kakimir> but anyways have anything critical changed if you use same code that runs on freertos 8.0

2017-11-30T18:14:08 < kakimir> hello pump
2017-11-30T18:17:31 < kakimir> you need to use heap number 4 even when your ram consists of continious address space?
2017-11-30T18:17:44 < kakimir> but has these 3banks
2017-11-30T18:17:54 < kakimir> every of those enabled
2017-11-30T18:18:47 < kakimir> I thought you can access continious sram address space as whole
2017-11-30T18:19:02 < kakimir> anyways my heap3 is still working
2017-11-30T18:22:22 < kakimir> anyone have example code for uint32_t -> hex formated acsii string?

2017-11-30T18:31:52 < kakimir> thanks qyx
2017-11-30T18:32:36 < qyx> and null terminate it just to be sure
2017-11-30T18:33:53 < kakimir> , n part?
2017-11-30T18:34:06 < qyx> n is the uint32_t number
2017-11-30T18:34:23 < qyx> no, the string blah
2017-11-30T18:34:47 < qyx> snprintf doesn't add explicit \0 if the value overflows past sizeof(blah)
2017-11-30T18:35:00 < kakimir> good to know
2017-11-30T18:35:15 < kakimir> I thought it was foolproof
2017-11-30T18:35:38 < qyx> aha maybe not
2017-11-30T18:35:44 < qyx> actually snprintf always null terminate
2017-11-30T18:36:16 < qyx> there was some other *n* function which was unfunny

2017-11-30T19:12:10 < kakimir> did she have a choise?

2017-11-30T19:12:14 < PaulFertser> Laurenceb: but it's like 26 years since soviet is gone, so that doesn't seem possible.
2017-11-30T19:12:36 < kakimir> some research institutes was left
2017-11-30T19:12:47 < PaulFertser> Yes, but they're not soviet anymore.
2017-11-30T19:13:01 < kakimir> maybe she was a prodigy
2017-11-30T19:13:11 < PaulFertser> Also, I'd expect someone to graduate from some uni before being hired by a research institute.

2017-11-30T19:17:00 < Laurenceb> she typically turns up for "work" at 4pm
2017-11-30T19:17:18 < kakimir> like I do
2017-11-30T19:17:23 < kakimir> but not drunk
2017-11-30T19:17:31 < Laurenceb> but as the supervisor only ever sends idiotic emails about once a week nobody cares

2017-11-30T19:17:45 < Laurenceb> she has vodka under desk
2017-11-30T19:18:04 < Laurenceb> this morning she has 4kg of chocolate cake

2017-11-30T21:48:22 < Steffanx> mcuxpresso is the new lpcxpresso where they intergrated the lpc and freescale tooling
2017-11-30T21:48:23 < Steffanx> s
2017-11-30T21:48:36 < Steffanx> *combined
2017-11-30T21:48:39 < kakimir> sweet
2017-11-30T21:48:46 < kakimir> time to migrate this shit
2017-11-30T21:48:51 < kakimir> *shiet sorry
2017-11-30T21:49:15 < kakimir> there is no code red in it anymore it seems
2017-11-30T21:49:17 < Steffanx> what heap*.c did kakimir use again?
2017-11-30T21:49:19 < Steffanx> there is.
2017-11-30T21:49:25 < kakimir> heap3
2017-11-30T21:49:32 < zyp> heap of shit
2017-11-30T21:49:32 < Steffanx> at least there is redlib.
2017-11-30T21:49:38 < kakimir> that
2017-11-30T21:49:59 < Steffanx> simply wraps the standard malloc() and free() for thread safety <3
2017-11-30T21:50:13 < kakimir> mcuxpresso?
2017-11-30T21:50:28 < Steffanx> no heap3. Just quoted freertos.website
2017-11-30T21:50:28 < kakimir> heap3?
2017-11-30T21:50:37 < kakimir> that is why those work nicelly
2017-11-30T21:51:05 < kakimir> I have not tried to interrupt those malloc-free ranges
2017-11-30T21:53:22 < kakimir> Steffanx: url=?
2017-11-30T21:53:31 < kakimir> that same old heap page?
2017-11-30T21:54:07 < Steffanx> Yes sir.
2017-11-30T21:54:32 < kakimir> https://www.freertos.org/FreeRTOS_Support_Forum_Archive/April_2017/freertos_heap3_203131f9j.html
2017-11-30T21:54:36 < kakimir> If you are using heap3 then malloc() is provided by your compiler, so
2017-11-30T21:54:36 < kakimir> we can't answer this and you will need to refer to the compiler
2017-11-30T21:54:36 < kakimir> documentation or vendor support. However, heap3 uses crude scheduler
2017-11-30T21:54:36 < kakimir> locks to ensure calls to malloc() and free cannot be interrupted by
2017-11-30T21:54:39 < kakimir> other tasks.
2017-11-30T21:55:12 < kakimir> old info?
2017-11-30T21:56:26 < Steffanx> old but still relevant?
2017-11-30T21:57:22 < kakimir> okay so task can not be interrupted between malloc and free
2017-11-30T21:57:29 < kakimir> by a task
2017-11-30T21:58:15 < kakimir> still better to use vPort functions then if timing is critical?
2017-11-30T21:58:28 < Steffanx> No, just the calls itself cannot be interrupted. At least that's how i interpret that sentence.
2017-11-30T21:58:59 < Steffanx> -s
2017-11-30T21:59:59 < Steffanx> Would be interesting if you allocate memory to never free it, if what you said is true kakimir :P
2017-11-30T22:01:14 < kakimir> certainly it can't disable tasks interupting between malloc free
2017-11-30T22:01:28 < kakimir> sometimes you malloc but never free
2017-11-30T22:02:23 < kakimir> so lpcxpresso is version 8.2
2017-11-30T22:02:31 < kakimir> this one is like 10.1
2017-11-30T22:02:49 < kakimir> I wondered if nxp cares a shi
2017-11-30T22:03:42 < Steffanx> Why would they mr kakimir
2017-11-30T22:03:58 < kakimir> I mean their ide was like.. falling behind
2017-11-30T22:04:16 < Steffanx> Compared to anything ST provides it's not really falling behind :P
2017-11-30T22:04:21 < Steffanx> And when you dont hate eclipse.
2017-11-30T22:04:54 < kakimir> I start to learn eclipse
2017-11-30T22:05:14 < kakimir> but lpcxpresso was like based on some 2010 eclipse
2017-11-30T22:05:43 < kakimir> then I saw no updates has been released since like last year
2017-11-30T22:06:02 < kakimir> assumed they were done with it
2017-11-30T22:07:04 < Steffanx> The latest lpcxpresso didnt have to code size limit anymore either.
2017-11-30T22:07:42 < Steffanx> /to/that/

2017-11-30T22:08:35 < kakimir> mine has
2017-11-30T22:08:41 < kakimir> i think it's latest
2017-11-30T22:08:44 < kakimir> 8.2.2 or so
2017-11-30T22:09:05 < kakimir> unregisted version 8k size limit
2017-11-30T22:09:42 < Steffanx> Really? I only know about some 256k limit it had once
2017-11-30T22:10:07 < kakimir> waa
2017-11-30T22:11:11 < kakimir> what is _sbrk_r?
2017-11-30T22:11:55 < Steffanx> Google it, but it's probably irrelevant when you use heap3
2017-11-30T22:12:37 < Steffanx> it's more useful when you do not use heap3 and want other calls to malloc to use calls to for example pvMalloc etc.
2017-11-30T22:12:56 < kakimir> if I want to use heap with higher number?
2017-11-30T22:14:16 < Steffanx> No, you can use it when you want functions that call malloc not let malloc do its magic, but "redirect" it to your own allocation functions.
2017-11-30T22:14:35 < Steffanx> like chibios http://chibios.sourceforge.net/html/syscalls_8c_source.html
2017-11-30T22:16:52 < kakimir> it's no problem to use vPortMalloc instead of malloc
2017-11-30T22:17:34 < kakimir> I fear that I need to change to higher heap number sooner or later
2017-11-30T22:18:22 < kakimir> to let heap expand across sram banks
2017-11-30T22:18:58 < Steffanx> if you use heap3 and that uses malloc, its likely you have to do the heap magic in the linker script as well.
2017-11-30T22:21:25 < kakimir> oh
2017-11-30T22:22:02 < Steffanx> but mcuxpresso has this fancy setting for it in C/C++ Build > Settings > Managed Linker Script
2017-11-30T22:22:26 < Steffanx> Like a real keil guy you should do it all using a GUI
2017-11-30T22:22:37 < Steffanx> Makes you feel more pro.
2017-11-30T22:24:11 < kakimir> it makes you cool
2017-11-30T22:24:31 < upgrdman> does digikey (or any tool i guess) have a way to see if a part uses a common footprint/design? e.g. if im looking for a regulator, but want to have multiple sources for pin-compatible ones, is there a way to see that?

2017-11-30T23:41:55 < kakimir> how it that in wireless bridge mode speed is halved?
2017-11-30T23:42:18 < kakimir> just watching some linustechtips infortainment
2017-11-30T23:42:31 < BrainDamage> because wifi is half duplex
2017-11-30T23:42:38 < BrainDamage> it has to receive, store, and retransmit
2017-11-30T23:44:11 < zyp> does it matter?
2017-11-30T23:44:21 < zyp> run cables to anything that needs speed
2017-11-30T23:44:53 < kakimir> what if it's only a 2 point link BrainDamage ?

2017-11-30T23:45:13 < kakimir> radios talk to each other only
2017-11-30T23:45:29 < kakimir> there is no AP at the other end
2017-11-30T23:45:36 < kakimir> just a wire
2017-11-30T23:45:46 < zyp> speed is halved vs what then?
2017-11-30T23:46:51 < zyp> a client bridging to cabled lan isn't really different from any other client, so there's no speed impact there
2017-11-30T23:47:36 < BrainDamage> it's only routers in repeater mode that suffer from speed penalty
2017-11-30T23:47:55 < BrainDamage> the moment you translate to a wire, you don't have to toggle the radio on/off more than you would with a reg ap/client
2017-11-30T23:47:57 < kakimir> that is what I thought
2017-11-30T23:48:49 < kakimir> so I set my ubiquiti side as Access Point WDS
2017-11-30T23:49:09 < kakimir> and another side router to be yet selected as Station WDS
2017-11-30T23:49:46 < kakimir> and I have transparent bridge?
2017-11-30T23:51:04 < kakimir> sweet
2017-11-30T23:54:33 < kakimir> I wonder if there is downsides to WDS
2017-11-30T23:54:57 < qyx> in wds repeater mode the speed is (at least) halved
2017-11-30T23:55:04 < qyx> but wds repeater !'wds bridge
2017-11-30T23:55:11 < qyx> *!=
2017-11-30T23:55:57 < qyx> wds just adds a second ethernet header on top of 802.11 to allow more mac addresses on the 802.11 client side
2017-11-30T23:56:09 < qyx> otherwise fancy things are needed, such as L2 NAT or similar
