2015-03-01T00:36:12 < Laurenceb_> dunno
2015-03-01T00:36:18 < Laurenceb_> makes no sense to me
2015-03-01T00:36:31 < Laurenceb_> im wondering if it doesnt like repeated start between devices
2015-03-01T00:38:17 < emeb> i2c bug?
2015-03-01T00:38:36 < Laurenceb_> no its there on the logic analyser
2015-03-01T00:38:43 < Laurenceb_> might be an l3gd20 i2c bug
2015-03-01T00:38:59 < Laurenceb_> datasheet says  "transaction must be terminated with a stop condition"
2015-03-01T00:39:00 < emeb> that *never* happens. :P
2015-03-01T00:39:09 < Laurenceb_> but thats not in the i2c spec
2015-03-01T00:39:36 < Laurenceb_> doh all my work rewriting i2c driver to be fast :P
2015-03-01T00:39:55 < Laurenceb_> i can change the priorities so L3GD20 sensor goes last

2015-03-01T03:20:24 < emeb> no major errors yet
2015-03-01T03:20:57 < emeb> usb OTG, ethernet, sdio, uart, RTC, battery all ok
2015-03-01T03:21:07 < dongs> do teh testing zano style
2015-03-01T03:21:12 < dongs> test out each individual component
2015-03-01T03:21:14 < dongs> but never all at once
2015-03-01T03:21:18 < emeb> heh
2015-03-01T03:21:19 < dongs> this way you'll never know if it works!
2015-03-01T03:22:02 < emeb> testing everything at once is haaaaaaaaaaard
2015-03-01T03:23:14 < emeb> next thing is to hook up an FPGA board and see if I can talk to it via SPI and I2C
2015-03-01T03:24:38 < dongs> some boner cape
2015-03-01T03:24:51 < GargantuaSauce> reverse boner cape isnt it

2015-03-01T03:25:28 < dongs> like that.
2015-03-01T03:26:08 < emeb> want to try this on it: http://ebrombaugh.studionebula.com/radio/adsb-cape/index.html
2015-03-01T03:26:09 < dongs> dat barrel jack footprint
2015-03-01T03:26:23 < emeb> dongs: yeah - sux not being able to do slots
2015-03-01T03:36:56 < qyx_> it seems thats not copper
2015-03-01T03:37:06 < dongs> oxygen-free copper
2015-03-01T03:37:06 < qyx_> if you look closer at thermals
2015-03-01T03:37:11 < dongs> so no problem
2015-03-01T03:39:09 < dongs> R2COM: how easy is it to make traces like http://i.imgur.com/nFKy50E.jpg in your favorite orcad
2015-03-01T03:40:07 < dongs> (while length matching them
2015-03-01T03:40:21 < dongs> does it tell you the length while you route?
2015-03-01T03:41:41 < dongs> how is left/right pair length matching done on that kinda layout? is it because they lave those left/right bends?
2015-03-01T03:42:12 < dongs> cuz i dont see them adding individual squigglies
2015-03-01T03:44:32 < dongs> ya that
2015-03-01T03:44:36 < dongs> but these traces dont have it
2015-03-01T03:44:44 < dongs> so i presume they matched it somehow just by doing left/right bends
2015-03-01T03:44:48 < emeb> R2COM: some of the daughter-boards (capes) that I've made for Beaglebone are RF. BBB is very RF noisy. Want to try with quieter processor.
2015-03-01T03:44:49 < dongs> or just didnt care
2015-03-01T03:50:23 < emeb> R2COM: something that doesn't pull so much current, doesn't have MHz-range switchers onboard, etc.
2015-03-01T03:51:16 < emeb> sure - can be done if you're in control of everything.
2015-03-01T03:51:31 < emeb> but BBB is a shitshow when it comes to RF emissions.
2015-03-01T03:51:43 < emeb> and I don't control it.

2015-03-01T04:00:29 < green1> hello,
2015-03-01T04:01:39 < green1> there are 2 analog pin config options ,   PC0  > ADC0_IN10  and GPIO_Analog
2015-03-01T04:02:10 < green1> what is the difference between these 2 ?
2015-03-01T04:20:20 < dongs> green1: none
2015-03-01T04:20:34 < dongs> green1: gpio_analog is just a state where pin is analog input not connected to anything
2015-03-01T04:20:43 < dongs> where adc_xx connects it to adc for use
2015-03-01T04:21:00 < dongs> you generally set all unused pins to taht so they dont draw current/make noise
2015-03-01T04:21:31 < green1> i see , thank you

2015-03-01T04:56:51 < dongs> in altidong i just click and drag and it adds swquigglies
2015-03-01T04:57:05 < dongs> and i can control thier height/pitch/smoothness with keyboard
2015-03-01T04:57:08 < dongs> while its making them
2015-03-01T04:57:14 < dongs> and it shows realtime trace length while updating
2015-03-01T04:59:18 < dongs> also the squiggly objects don't become permanent part of trace
2015-03-01T04:59:31 < dongs> so if I dont like the squiggly i just delete the entire squiggly object, and I don't need to re-route the trace

2015-03-01T05:20:58 < dongs> i guess if they were really nasty they'd put all the pots into like 4V output

2015-03-01T05:25:21 < emeb_mac> how do you use color?
2015-03-01T05:25:51 < dongs> its just common anode or whatever rgb
2015-03-01T05:26:01 < dongs> on that board one can be PWMd the other are just on/off
2015-03-01T05:28:05 < emeb_mac> right - but do different colors / brightnesses imply different functions in your control scheme?
2015-03-01T05:28:44 < dongs> yea, of course
2015-03-01T05:29:08 < dongs> blue on,  red standby, off = duh. and long-push modes are different color

2015-03-01T13:03:17 < PeterM> there isnt, and these days, there are single chips that do it for less than $10 that are better than 90% of amps from the past 50 years

2015-03-01T14:25:10 < karlp> sorry, yeah, df12
2015-03-01T14:25:34 < karlp> just wondering if you used it standard in lots of places,
2015-03-01T14:25:37 < dongs> ive used smaller pin count ones before for other stuf,f this time i'll be d oing 40 pin tho
2015-03-01T14:25:41 < dongs> it is fairly standard/common
2015-03-01T14:25:44 < dongs> lots of them in china too

2015-03-01T14:26:12 < karlp> hoping df62 is in china too :)

2015-03-01T14:28:35 < dongs> or is taht too big
2015-03-01T14:28:39 < karlp> only need 4 pins, would like smaller

2015-03-01T14:29:45 < karlp> cable needs to get double insulation on it too, whicih is tedious.

2015-03-01T19:05:17 < Getty> noob question, does MIDI over 1-Wire sound like something doable? i dont know both protocols good enough to make a statement, cant find anything, is that a weird thought?
2015-03-01T19:10:15 < zyp> wat
2015-03-01T19:10:20 < zyp> why would you do that?
2015-03-01T19:10:37 < Getty> well.... "situation"
2015-03-01T19:10:37 < zyp> midi is already a single wire per direction
2015-03-01T19:10:49 < Getty> yeah no, i mean if we put something in between
2015-03-01T19:10:55 < Getty> i mean i dont mean like DIRECTLY wire them
2015-03-01T19:11:30 < Getty> wait..... i am stupid, i am a STM32, i do whatever i wan with those pins....
2015-03-01T19:11:39 < Getty> but MIDI is more then 2 wires, right?
2015-03-01T19:14:08 < Getty> oh wait i just need one direction..... then i can use the 2 wires of the 1-wire (hehe still cant get over that) just like a MIDI
2015-03-01T19:14:28 < Getty> one ground, one for the one direction, yeah, that can work, right? MIDI on the STM32?
2015-03-01T19:15:38 < dongs> bro
2015-03-01T19:15:40 < dongs> midi is just fucking uart
2015-03-01T19:15:43 < dongs> at some retarded baudrate
2015-03-01T19:16:50 < Getty> yeah seeing that now in the article
2015-03-01T19:16:59 < Getty> so my plan actually makes sense, which is awesome :)

2015-03-01T20:01:27 < zyp> Getty, no, it doesn't make sense at all
2015-03-01T20:01:45 < Getty> zyp: why?
2015-03-01T20:03:29 < Getty> zyp: seems like you know a lot of my situation, so i am curious what better idea you have
2015-03-01T20:04:09 < zyp> once more, exactly what are you proposing?
2015-03-01T20:06:28 < Getty> i have 2 wires exposed on a STM32, which i p.d. use as 1-Wire, and i thought i could make MIDI over it, after realising what MIDI just is, and remembering that i can use the wires for whatever i want, it sounds like a reasonable plan
2015-03-01T20:06:38 < Getty> wasnt that obvious by my statements?

2015-03-01T20:07:47 < zyp> I interpreted your plan as transporting MIDI data over the 1-Wire protocol, which would be very unsuitable for that purpose
2015-03-01T20:11:01 < Getty> [18:11:30] <Getty> wait..... i am stupid, i am a STM32, i do whatever i wan with those pins....
2015-03-01T20:11:16 < Getty> wasnt that clear enough statement that i dont need to be "1-wire"? ;)
2015-03-01T20:11:53 < zyp> no
2015-03-01T20:12:05 < Getty> ok ;) now you know
2015-03-01T20:12:32 < Getty> but yeah at first i wanted to convert MIDI data to something i can send via 1-Wire, but thats how brain works for beginners: slowly

2015-03-01T20:44:53 < Getty> how is that actually when you write for multiply cores (without linux, i mean like "raw" ;) )? how is that working codewise? is it like that there is a command "execute this memory position on CPU X"? or is that more complex?
2015-03-01T20:45:01 < Getty> (just curious, not actually needing it)
2015-03-01T20:45:20 < superbia> you take computer arhitecture 2+
2015-03-01T20:45:46 < Getty> hehehe so, its totally far away from that command? ;)
2015-03-01T20:46:04 < scummos> I recently did that on an LPC433x, it has a master and a slave core
2015-03-01T20:46:16 < scummos> and basically the slave has its own interrupt table and everything
2015-03-01T20:46:30 < Getty> and how you "kick" it on?
2015-03-01T20:46:32 < scummos> and the master sets the location of the interrupt table and then resets the slave, and then the slave starts executing the reset ISR
2015-03-01T20:46:38 < Getty> ok
2015-03-01T20:46:58 < scummos> and there is some means of communication between the two (except the obvious shared memory approach), but I didn't read into that
2015-03-01T20:47:26 < Getty> yeah i bet depending on which multicore architecture you will get more and more share concepts ;) thats clear

2015-03-02T03:31:28 < qyx_> isn't there some small form factor high speed m0+?
2015-03-02T03:31:40 < dongs> LIS334EB or somethign

2015-03-02T03:34:12 < dongs> is it???
2015-03-02T03:34:14 < dongs> how so
2015-03-02T03:34:24 < dongs> i did it and had no problem
2015-03-02T03:34:26 < qyx_> i could but then i would need to change all the timers and prescalers ant shit
2015-03-02T03:34:47 < qyx_> and comms interfaces
2015-03-02T03:36:02 < qyx_> and i need to maintain 1MHz timers without introducing some phase delays
2015-03-02T03:36:19 < qyx_> ir did i miss something?
2015-03-02T03:36:35 < qyx_> could i clock the core dynamically and all the peripherals will keep the same clock?

2015-03-02T03:49:05 < kakeman> inside group of solid electrolytes
2015-03-02T03:50:38 < kakeman> nichicon sheets are pure data
2015-03-02T03:51:08 < Getty> i dont need to feel bad if i need to add like net_loop();net_loop();net_loop();net_loop();net_loop(); to give the net loop call enough priority against the rest?
2015-03-02T03:51:53 < qyx_> wut?
2015-03-02T03:52:40 < dongs> kickstarter cap
2015-03-02T03:52:41 < Getty> well the lwip loop function to call whenever there is time, if i dont call it often (together with my other "Program") then it misses out dhcp answers
2015-03-02T03:54:32 < kakeman> lets try
2015-03-02T03:55:08 < qyx_> Getty: are you just cooperatively running your tasks in a round-robin style?
2015-03-02T03:56:34 < dongs> <Getty> Tasks?? wuzzat??

2015-03-02T03:58:22 < Getty> totally
2015-03-02T04:00:26 < qyx_> pff, use a timer for it at least
2015-03-02T04:00:42 < qyx_> if the lwip can be called from two contexts without any special locking

2015-03-02T04:01:00 < dongs> or just run it from syutick?
2015-03-02T04:01:11 < qyx_> or that but the same apply
2015-03-02T04:01:16 < dongs> rite
2015-03-02T04:02:13 < Getty> yeah systick was like an idea i had first, but then i thought lets see if several calls is already enough, and the effect is massive
2015-03-02T04:02:46 < Getty> like if i do it 3 times between the other "tasks" its still taking forever, but already making it 6 calls is "fixing" the situation complete
2015-03-02T04:02:47 < qyx_> whatever you do, you shouldn't be blocking for a long time in your "run loop"
2015-03-02T04:02:50 < Getty> more is not making it better
2015-03-02T04:03:09 < Getty> yeah its just a lot of things he has todo, but those things can be always a bit delayed, so its not really having impact
2015-03-02T04:03:33 < Getty> but i try it out in systick too, not like every systick ;) but often
2015-03-02T04:03:35 < qyx_> not much realtime design
2015-03-02T04:03:48 < Getty> not really a realtime design, yeah, not the target for now :)
2015-03-02T04:04:27 < qyx_> consider reentrancy problems then (when using a systick)
2015-03-02T04:04:41 < qyx_> or more like locking problems
2015-03-02T04:04:44 -!- bvsh_ is now known as bvsh
2015-03-02T04:05:44 < Getty> yeah i would more like do it every X calls
2015-03-02T04:06:20 < Getty> i think/feel the call to net_loop() is actually nearly free if he has nothing todo, the problem is just the "being called in the right moment"
2015-03-02T04:06:36 < Getty> all experiences i have to make, i mean its not often that you have to care about that the package is not GONE before you fetch it ;)

2015-03-02T05:57:43 < Getty> oh can someone explain to me why i have to cast this? (int32_t)(time_in - diff) <= 0 is it like cause the other vars are unsigned and so he just makes it unsigned by default?
2015-03-02T06:04:57 < GargantuaSauce> don't do that
2015-03-02T06:07:49 < Getty> what else? i mean at first i had time_in - diff <= 0 and then after going wild i saw that time_in - diff is unsigned if i dont cast it
2015-03-02T06:08:59 < GargantuaSauce> casting a uint that > INT_MAX to signed int = here be dragons
2015-03-02T06:09:45 < Getty> yeah but again... if i do time_in - diff and it gets negative, he makes it the unsigned value for the compare
2015-03-02T06:10:10 < GargantuaSauce> so don't do that
2015-03-02T06:10:22 < Getty> and how else i should do it?
2015-03-02T06:10:50 < GargantuaSauce> can diff actually be negative?
2015-03-02T06:10:59 < Getty> no both are unsigned
2015-03-02T06:11:13 < GargantuaSauce> then use the >= operator on the two of them duh

2015-03-02T06:12:24 < Getty> gargantuasauce: i am not following.... the only way i can avoid going negative is checking before whats bigger, or i miss something obvious here 8-)
2015-03-02T06:12:51 < GargantuaSauce> do some basic algebra to remove the subtraction from the comparison
2015-03-02T06:13:01 < GargantuaSauce> time_in <= diff

2015-03-02T06:16:59 < GargantuaSauce> i dont want to get into language lawyering bullshit Getty but be extremely careful about what you're doing when mixing signed and unsigned or subtracting unsigned or casting between them or anything like that
2015-03-02T06:17:04 < GargantuaSauce> lots of stupid pitfalls there
2015-03-02T06:17:19 < dongs> lunix pitfaslls
2015-03-02T06:17:51 < Getty> GargantuaSauce: yeah i just need first to understand what is happening
2015-03-02T06:18:09 < Getty> gargantuasauce: so i am in general right with the statement that the result of unsigned - unsigned is always unsigned, right?
2015-03-02T06:18:13 < Getty> thats the "core" of my problem here?
2015-03-02T06:18:56 < GargantuaSauce> the statement is true but i dunno if i'd call it the core of the problem
2015-03-02T06:19:11 < Getty> yeah well, for me its first understandment of how the language "act"
2015-03-02T06:19:18 < GargantuaSauce> cause casting them both before subtracting could invoke implementation-dependent behaviour
2015-03-02T06:19:21 < Getty> its like... a PRETTY UNCOMMON behaviour ;)
2015-03-02T06:19:22 < GargantuaSauce> if either are > INT_MAX
2015-03-02T06:20:03 < Getty> i already learned the hard way that i should always add a lot of () to be sure what is happening
2015-03-02T06:21:07 < Getty> but if i REALLY need to get a negative value out, what is the most safe way? what thought process i have to make?
2015-03-02T06:21:20 < Getty> i will for sure avoid it, but i feel a bit scared now :)
2015-03-02T06:22:12 < GargantuaSauce> i guess it's safe to cast the operands of - (not the result) if you compare to INT_MAX first
2015-03-02T06:22:42 < Getty> so in my case like (int32_t)time_in - (int32_t)diff ?
2015-03-02T06:23:04 < GargantuaSauce> yeah
2015-03-02T06:24:29 < Getty> ok, need to get used to that
2015-03-02T06:24:35 < Getty> i mean to avoid this ;)

2015-03-02T06:24:59 < GargantuaSauce> you can get away without the comparison first if you're certain they're reasonably sized of course
2015-03-02T06:25:09 < GargantuaSauce> or if you don't care about the code randomly breaking if you switch compilers or platforms
2015-03-02T06:26:04 < Getty> i will just store it in my brain as the signed and unsigned world, and i have to move things to the worlds before working with them in those worlds ;)

2015-03-02T08:26:31 < dongs> R2COM, I have put you on a permanent ignore, public and private. I have found you disturbing, rude and generally not worth talking to. According to the channels you hang on, it strengtens the effect of wanting to put you on ignore because of my lack of interest in you as a person. This message is not meant to be rude to you, just to inform you that i won't see anything of what you type from now on.

2015-03-02T12:45:55 < Roklobsta> ? i thought matlab did a nice job on matlab code speedwise.  it's much better than octave that's for sure.
2015-03-02T12:46:00 < Roklobsta> use fortran
2015-03-02T12:46:07 < Laurenceb> im using ancient matlab

2015-03-02T12:49:15 < Laurenceb> yeah
2015-03-02T12:49:27 < Laurenceb> but i could rewrite all my lame code in c
2015-03-02T12:49:30 < Laurenceb> if i wasnt lazy
2015-03-02T12:49:33 < Roklobsta> yep
2015-03-02T12:49:37 < dongs> lazy isnt the probelm
2015-03-02T12:49:40 < dongs> your C code is shit
2015-03-02T12:49:53 < Roklobsta> yeah how do you do x=a' in C?
2015-03-02T12:50:01 < Roklobsta> without s hitload of for loops
2015-03-02T12:50:11 < Roklobsta> ok 1o for loop
2015-03-02T12:50:50 < Roklobsta> at least do it in fortran so you can feel a little bit leet
2015-03-02T12:51:33 < Laurenceb> thats true
2015-03-02T12:51:51 < Laurenceb> most of the cpu time is spent fitting polynomials to data
2015-03-02T12:51:55 < trepidaciousMBR> What does x=a' mean?
2015-03-02T12:52:04 < Laurenceb> maybe i could call a c library to do that
2015-03-02T12:52:15 < Laurenceb> <trepidaciousMBR> x is a transpose
2015-03-02T12:52:24 < trepidaciousMBR> Ah a is a matrix?
2015-03-02T12:52:28 < Laurenceb> or rather "set x to transpose of a"
2015-03-02T12:52:30 < Laurenceb> yes
2015-03-02T12:52:41 < trepidaciousMBR> Which language is that?
2015-03-02T12:52:47 < Laurenceb> matlab/octave
2015-03-02T12:52:52 < Laurenceb> and fortran?
2015-03-02T12:53:03 < Laurenceb> ive never used fortran
2015-03-02T12:53:21 < trepidaciousMBR> Closest I've been is using some numerical stuff ported from fortran
2015-03-02T12:53:24 < Roklobsta> there's probably a nice optimised lib out there that does it already
2015-03-02T12:53:27 < Laurenceb> yeah
2015-03-02T12:53:48 < Laurenceb> i have a samba system setup for my datalogger users to submit files
2015-03-02T12:53:51 < Roklobsta> it's 2015 and everything you can think of has been done by someone else better than you.
2015-03-02T12:53:55 < Laurenceb> heh
2015-03-02T12:54:11 < trepidaciousMBR> Plus they have used it a lot longer and got all obsessive about it ;)
2015-03-02T12:54:13 < Laurenceb> problem is average file is 250MB
2015-03-02T12:54:34 < Roklobsta> so even dongs just rehashes crap someone else did before.
2015-03-02T12:54:36 < Laurenceb> huge wav files of mems sensor data
2015-03-02T12:55:13 < Roklobsta> modern circuit design is lego anyway.  you can leave your brain at the door.
2015-03-02T12:55:30 < Laurenceb> then they get processed to a single page report and appended to a huge pdf for each vehicle in their fleet
2015-03-02T12:55:47 < jpa-> just 90% of it is lego, and the leftover 10% is what makes the difference
2015-03-02T12:55:51 < Laurenceb> and stuck in appropriate directory on the network drive for that customer
2015-03-02T12:55:58 < jpa-> part of that is choosing the right pieces
2015-03-02T12:56:04 < Laurenceb> its pretty simple but the code is just a load of matlab hacking
2015-03-02T12:56:53 < Roklobsta> god i hate the new HaD layout.  I don't want to visit it any more.
2015-03-02T12:57:53 < jpa-> use rss?
2015-03-02T12:58:24 < Roklobsta> ass?
2015-03-02T12:59:38 < Roklobsta> I am beginning to see the world as if through dong's merde tinted googles.

2015-03-02T16:05:07 < _Sync_> sounds good
2015-03-02T16:05:17 < Laurenceb> holy shit thats low resistance
2015-03-02T16:07:00 < _Sync_> nah
2015-03-02T16:07:12 < _Sync_> at 60V that is not amazeballs
2015-03-02T16:08:28 < dongs> i'll be using it at 55-ish V
2015-03-02T16:08:31 < dongs> hopefully thats close enough
2015-03-02T16:09:59 < _Sync_> err
2015-03-02T16:10:07 < _Sync_> in a boostconv?
2015-03-02T16:10:12 < _Sync_> that might be a leetle close
2015-03-02T16:10:13 < dongs> yeah
2015-03-02T16:10:45 < _Sync_> go for a 100V fet

2015-03-02T18:02:47 < Laurenceb>  lol @ "social websites"
2015-03-02T18:02:58 < Laurenceb> hmmm
2015-03-02T18:03:17 < Laurenceb> dongs you should make a A7LW based mini quad
2015-03-02T18:03:22 < emeb> camera brief...

2015-03-02T18:03:31 < Laurenceb> NDA tiem
2015-03-02T18:03:51 < dongs> ambarella are jews
2015-03-02T18:03:57 < dongs> they wont give any docs unless you're gopro or sony

2015-03-02T18:04:15 < englishman> What's blogging fellow bloggers
2015-03-02T18:04:17 < dongs> that sounds like something from 2 decadesa go
2015-03-02T18:04:18 < Laurenceb> lol ARM11
2015-03-02T18:04:24 < Laurenceb> yup
2015-03-02T18:04:28 < dongs> where they did that on CVBS/Svideio shit
2015-03-02T18:04:30 < Laurenceb> still pwns pic32
2015-03-02T18:05:21 < _Sync_> kek 1080@30
2015-03-02T18:05:48 < Laurenceb> way better than zano
2015-03-02T18:05:58 < emeb> RPi level
2015-03-02T18:06:01 < _Sync_> yeah ambarella are serious assholes getting infos from them
2015-03-02T18:06:17 < dongs> zano will never be able to stream 720p to sd card
2015-03-02T18:06:22 < dongs> not with ~400k ram as buffer
2015-03-02T18:06:39 < dongs> especially not as mjpeg, even at 150k/frame
2015-03-02T18:07:56 < dongs> 30fps = ~33ms/frame, SD card can stall up to 250ms, so he needs at least 7 frames buffer
2015-03-02T18:08:02 < dongs> and pray the stall  never reaches 250ms
2015-03-02T18:08:04 < ReadError> just funny they have the serial # for ThreadX in their binary
2015-03-02T18:08:14 < dongs> so > 1meg buffer
2015-03-02T18:08:24 < dongs> ReadError: its as much their binary as it is just copypaste of ambarella SDK
2015-03-02T18:08:25 < Laurenceb> decent µSD doesnt stall that long
2015-03-02T18:08:29 < dongs> which is probably why they dont give a shit
2015-03-02T18:08:34 < dongs> Laurenceb: it *does*, its in the spec
2015-03-02T18:08:45 < Laurenceb> not when i benchmark decent cards

2015-03-02T18:09:25 < Laurenceb> my GoPro rejects cheap cards
2015-03-02T18:09:33 < Laurenceb> it does some sort of benchmarking
2015-03-02T18:09:39 < dongs> wrong
2015-03-02T18:09:42 < dongs> it just reads the header

2015-03-02T20:21:23 < yan_> jpa-: this is the compiler output of a standard SystemInit func (that does hw-based initialization) of code that ships with the hardware
2015-03-02T20:21:35 < yan_> jpa-: it produces 'correct' looking code with -O1
2015-03-02T20:24:53 < jpa-> at what optimization does it produce incorrect code?
2015-03-02T20:25:07 < jpa-> -Os was buggy for thumb2 in old gcc versions
2015-03-02T20:25:47 < yan_> jpa-: -O1 produces code that looks correct, -O0 produces code that is almost certainly wrong, -Os looks to be okay but i can't debug because none of the symbols are accurate
2015-03-02T20:27:41 < jpa-> haven't seen such bugs
2015-03-02T20:28:47 < GargantuaSauce> can you post source? i'd be inclined to look for undefined behaviour long before suspecting compiler issues
2015-03-02T20:30:30 < yan_> GargantuaSauce: i mean sure,but it's the SystemInit function in CMSIS that's shipped with SmartFusion2 boards.. (the core isn't stm32, but it's a cortex m3)

2015-03-02T22:41:46 < Getty> cant be "branded" much ;)
2015-03-02T22:42:10 < jadew> AmScope = Optika = some few other EU companies = lots of chinese companies
2015-03-02T22:42:15 < jadew> they all have the same scopes
2015-03-02T22:43:16 < jadew> and the prices vary from very cheap (china) to cheap (AmScope) and to obscenely-expensive-for-what-it-is (Optika & other EU shit-shops)
2015-03-02T22:43:26 < jadew> which sucks, because I'm in the EU
2015-03-02T22:46:34 < jadew> in EU they charge 4 to 7 times what they're worth (pre VAT!) and they say that it ships in 3-4 weeks lol
2015-03-02T22:48:02 < jadew> they're basically ordering it for you from china, after you pay them a lot more than what it's worth

2015-03-03T01:56:23 < qyx_> mhm did you try wideband?
2015-03-03T01:56:29 < Laurenceb_> huh?
2015-03-03T01:56:31 < qyx_> 50-100kbaud?
2015-03-03T01:56:34 < Laurenceb_> no way
2015-03-03T01:56:41 < Laurenceb_> im going for ultra narrow
2015-03-03T01:56:46 < Laurenceb_> 440hz filters
2015-03-03T01:57:10 < qyx_> yep i saw them
2015-03-03T01:57:16 < karlp> qyx_: ..... rfPIC? ;)
2015-03-03T01:57:20 < qyx_> pls
2015-03-03T01:57:25 < Laurenceb_> theoretically it should "just" be a matter of changing the setting with WDS
2015-03-03T01:57:29 < Laurenceb_> *settings
2015-03-03T01:58:20 < qyx_> did you use any additional filtering?
2015-03-03T01:58:24 < qyx_> compared to reference sch
2015-03-03T01:58:32 < Laurenceb_> void si446x_set_modem(void)

2015-03-03T02:00:03 < Laurenceb_> ive used two rx filters, 1khz for AFC then 440hz
2015-03-03T02:01:07 < qyx_> mhm, ok, thx
2015-03-03T02:01:27 < qyx_> i will finish the basic software part and then try the si446x board
2015-03-03T02:06:17 < Laurenceb_> for higher bps AFC is less important

2015-03-03T02:39:03 < dongs> i spotted a change on zano frontpage

2015-03-03T02:41:14 < qyx_> arduino compatible
2015-03-03T02:41:28 < GargantuaSauce> its just the single pic onboard right?
2015-03-03T02:41:29 < dongs> qyx_: apparently you can write modules for the STM32F2 thats on landongix module
2015-03-03T02:41:37 < dongs> GargantuaSauce: ^
2015-03-03T02:41:37 < GargantuaSauce> ah
2015-03-03T02:41:48 < dongs> the pic trash is tightly closed sores
2015-03-03T02:42:03 < GargantuaSauce> it's gonna be pretty damn busy pushing video anyway
2015-03-03T02:43:02 < qyx_> you will fly over a park with grass
2015-03-03T02:43:05 < qyx_> -> bigger frames
2015-03-03T02:43:07 < dongs> its already been determined it doent have enough mips (pun intended) for that
2015-03-03T02:43:07 < qyx_> -> stack overflow
2015-03-03T02:43:11 < qyx_> -> drop down
2015-03-03T02:44:10 < dongs> also his current amazing face avoidance-ir-spewing-gps-locked-fully-autonoumous PIC32 code is only using 1-2% CPU at 200MHz And the rest he's dedicating to "video processing"
2015-03-03T02:45:40 < GargantuaSauce> which is just sucking up mjpeg from one serial interface and spewing it to the rf module right?
2015-03-03T02:45:51 < dongs> thats all he can do, yes
2015-03-03T02:46:16 < GargantuaSauce> i wonder how much of the control loop is gonna end up on the phone
2015-03-03T02:48:13 < dongs> zero
2015-03-03T02:48:16 < dongs> it would be completely worthless
2015-03-03T02:48:18 < dongs> due to lag/etc

2015-03-03T02:49:21 < GargantuaSauce> that much is clear
2015-03-03T02:51:03 < dongs> i wonder when will they just give up

2015-03-03T03:05:49 < kakeman> but I think I need to perform some authentication in same message routine because line connecting devices is not protected
2015-03-03T03:06:23 < kakeman> and uncrypted
2015-03-03T03:06:24 < GargantuaSauce> you should use asymmetric encryption and get your device export-limited

2015-03-03T03:06:59 < GargantuaSauce> bonus points if you implement it yourself
2015-03-03T03:07:21 < qyx_> your echo messages would be emitted like one every 5secs

2015-03-03T03:07:51 < kakeman> around that
2015-03-03T03:07:52 < qyx_> you could arduino up some ed25519 code

2015-03-03T05:06:23 < kakeman> I think so too
2015-03-03T05:06:28 < zyp> linker should refuse to link if the code won't fit
2015-03-03T05:06:37 < GargantuaSauce> if the linker script is correctly written

2015-03-03T06:37:41 < louloulou> anyone home?
2015-03-03T06:37:53 < kakeman> certainly
2015-03-03T06:37:55 < zyp> yes, we are familiar with stm32 timers
2015-03-03T06:38:01 < zyp> please state your problem
2015-03-03T06:38:12 < louloulou> ok - I am very sorry for this stupid quiestion,
2015-03-03T06:38:45 < Getty> This goes as record for most precise meta question i heard so far => <lll> is anyone out there farmilar with stm32 timer 3 output compare unit?
2015-03-03T06:38:54 < louloulou> I have timer 3 set up in up cont mode. Works fine. I have I/C 1 set to capture, and then print - does exactly waht I expect..
2015-03-03T06:39:28 < louloulou> I swithed my name from LLL to Louloulou - I was having problems running my browser..
2015-03-03T06:40:17 < louloulou> I have I/C 1 set up to capture, and measure the delta from the last capture ( acts as a freq counter - works great, ISR running fine )
2015-03-03T06:40:42 < louloulou> BUT - what I need to do is every so often generate a pulse on OC2
2015-03-03T06:41:00 < louloulou> I have OC2 set up as output compare -
2015-03-03T06:41:18 < louloulou> and I have it se to go IN ACTIVE on match..
2015-03-03T06:41:22 < louloulou> Which it does..
2015-03-03T06:41:27 < louloulou> Once
2015-03-03T06:41:40 < louloulou> my question is how do I mahe the pin high again,
2015-03-03T06:41:50 < louloulou> when I want to do it over..
2015-03-03T06:42:06 < louloulou> I can get it to go one time, from high to low...
2015-03-03T06:42:22 < zyp> how long is your timer interval?
2015-03-03T06:42:23 < louloulou> but I can not ever get the OC2 pin high again.
2015-03-03T06:42:59 < zyp> usually in output capture, it'll toggle at the trigger point, and then back on timer overflow
2015-03-03T06:43:02 < louloulou> What am I missing? Is it supposed to go hig whenn I re-write the TIM_SetCompare2() function?
2015-03-03T06:43:30 < louloulou> hmm..
2015-03-03T06:43:33 < zyp> no, it's supposed to go high again when the count wraps around to 0
2015-03-03T06:43:57 < louloulou> I am using the std periph lib..
2015-03-03T06:44:03 < louloulou> here is my setup..
2015-03-03T06:44:25 < louloulou> TIM_OCStructInit(&TIM_OCInitStructure);
2015-03-03T06:44:32 < louloulou> TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Inactive;   //CHANELL WILL GO LOW ONMATCH
2015-03-03T06:44:39 < louloulou> TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
2015-03-03T06:44:47 < louloulou> TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
2015-03-03T06:44:53 < louloulou> TIM_OCInitStructure.TIM_Pulse = 0;
2015-03-03T06:45:11 < louloulou> Then, in the ISR, I do this..
2015-03-03T06:45:23 < louloulou>  TIM_SetCompare2(TIM3,I16_present_capture_count+1000);
2015-03-03T06:45:41 < dongs> i prefer to just do TIM3->CCRx = foo
2015-03-03T06:45:51 < dongs> been a while since i seen SetCompare shit in code
2015-03-03T06:45:56 < louloulou> The idea is that when the I/C pin is triggered, I want to ouput a high pulse for 1000 clocks
2015-03-03T06:46:07 < dongs> louloulou: you can do this in hardware by slaving channels I think
2015-03-03T06:46:12 < dongs> without having to do such horrible shit in ISR
2015-03-03T06:46:20 < louloulou> I sort of hate the std prepih lib..
2015-03-03T06:46:52 < louloulou> Unfortunatly its more complex than that..
2015-03-03T06:47:06 < louloulou> I have to do it once every 72 I/C events..
2015-03-03T06:47:23 < louloulou> so, rareley, I want to make a 1000 cycle wide pusle on oc2
2015-03-03T06:50:04 < louloulou> what is the mecanisim that re-sets the timer output pin active?
2015-03-03T06:50:13 < louloulou> I just chanegd the code to TIM3->CCR2 = (I16_present_capture_count+1000);
2015-03-03T06:50:15 < louloulou> no go..
2015-03-03T06:50:19 < louloulou> still stuck low.
2015-03-03T06:50:53 < dongs> do you have ARR set
2015-03-03T06:51:01 < dongs> so that it updates pulse width on CCR reload
2015-03-03T06:51:15 < louloulou> I have spent the day reading the stm32f0 reference manual - and its not clear what sets the damn output active.
2015-03-03T06:51:36 < louloulou> not sure - let me look at the bits..
2015-03-03T06:51:38 < louloulou> Good idea
2015-03-03T06:51:41 < dongs> is the question that youre not getting physical output?
2015-03-03T06:51:53 < louloulou> I do get output..
2015-03-03T06:51:56 < dongs> ah ok.
2015-03-03T06:52:08 < dongs> cuz i duno if TIM3 on F0 needs to have that ControlPWMOutputs shit set or not
2015-03-03T06:52:12 < louloulou> it is hig on reset, and runs once, and then just stays low
2015-03-03T06:52:26 < dongs> is it set to loop or whatever
2015-03-03T06:52:41 < louloulou> ISR is runnig the code - I can see it by watching a spare pin toggle (debug code)
2015-03-03T06:52:45 < dongs> TIM_OCMode_Inactive;   //CHANELL WILL GO LOW ONMATCH
2015-03-03T06:52:48 < dongs> also this looks silly
2015-03-03T06:52:51 < dongs> another possibility
2015-03-03T06:53:11 < louloulou> I am really learning to hate the std prepih lib.
2015-03-03T06:53:13 < dongs> why not just turn off OC when done, and just turn it on in the ISR once
2015-03-03T06:53:17 < dongs> stdperiphlib is fine
2015-03-03T06:53:53 < louloulou> let me look into the ARR
2015-03-03T06:54:15 < louloulou> the  ARR is se to 0 -

2015-03-03T07:01:58 < louloulou> seems to set  TIM2 and TIM3 capture/compare mode register 2 (TIM2_CCMR2 and
2015-03-03T07:04:22 < louloulou> looking at the bit descriptions of that register  - confusing at best.
2015-03-03T07:05:00 < louloulou> what do the  Output compare 4 clear enable and Output compare 4 preload enable bist do?
2015-03-03T07:05:44 < louloulou> are they used to re=-load the 16 bit compare registers? or d they set the output bits of the compare unit?

2015-03-03T07:08:16 < louloulou> no go
2015-03-03T07:09:42 < dongs> shouldnt it bt OC2

2015-03-03T07:09:52 < louloulou> I know
2015-03-03T07:09:59 < louloulou> I mis typed
2015-03-03T07:10:07 < louloulou> I tried it as OC2 - no go
2015-03-03T07:10:15 < louloulou> good catch though :)
2015-03-03T07:14:47 < louloulou> Man, this just cant be that complicated
2015-03-03T07:15:31 < louloulou> on all of the oter chips I have used, from NXP2468 to 'hc11 writing the capture compare with a new value automatically set the output bit.
2015-03-03T07:15:58 < louloulou> I am doing something stupid... the question is what?
2015-03-03T07:17:30 < louloulou> chaiging TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Active;
2015-03-03T07:17:42 < louloulou> makes the pin go high and stay that way..
2015-03-03T07:32:32 < dongs> why dont you set it to ocmode_pwm or something
2015-03-03T07:39:10 < louloulou> I can get the PWM mode to work, problem is that it re-starts the PWM cycle when the master counter overflows - GREAt if you want pwm, but I need a single pulse on rare occasion
2015-03-03T07:39:30 < louloulou> pwm works fine btw..
2015-03-03T07:46:06 < dongs> o
2015-03-03T07:46:14 < dongs> yea cuz you want it oneshot or whatever thing
2015-03-03T07:46:22 < louloulou> yup
2015-03-03T07:46:35 < dongs> havent dicked with that, im sure its very doable :)

2015-03-03T14:26:15 < scummos> I liked it
2015-03-03T14:27:20 < jpa-> isn't it more like "a kickstarter project exceeds its funding goals and fails as a result"
2015-03-03T14:27:47 < Steffanx> For some reason i do like it. Get a shitload of money and you are seem to be (legally) allowed to waste it, no one forces you to actually come with something useful.
2015-03-03T14:27:54 < jpa-> organization that can deliver 100 units perfectly ok can fail to deliver 10000 units
2015-03-03T14:29:20 < Steffanx> 100 units, that cost more to manufacture than they're sold for?

2015-03-03T15:06:31 < dongs> thats $15 on bom right there
2015-03-03T15:06:34 < dongs> fucking FAIL
2015-03-03T15:07:06 < jpa-> i'm surprised that there isn't an actual arduino inside the box :P
2015-03-03T15:07:10 < BrainDamage> probably the 350$ was the cost for all boards summed
2015-03-03T15:07:21 < jpa-> all boards?
2015-03-03T15:07:23 < dongs> wut
2015-03-03T15:07:31 < dongs> you mean ALL boards they have ever prototyped since day?
2015-03-03T15:07:34 < dongs> day 1
2015-03-03T15:07:35 < dongs> maybe.
2015-03-03T15:07:37 < BrainDamage> yes
2015-03-03T15:07:38 < dongs> but even that spushing it
2015-03-03T15:07:40 < dongs> I see like
2015-03-03T15:07:50 < dongs> maybe 2-3 boards worth of seedstudio 10 for $10 special
2015-03-03T15:07:55 < jpa-> the $350 wasn't BOM price, it was resale price
2015-03-03T15:07:58 < dongs> so they spent maybe $30 on PCBs
2015-03-03T15:08:41 < jpa-> so BOM is probably $100 or something, then assembly etc. and profit margin bring it to $350
2015-03-03T15:08:52 < dongs> how the fuck is BOM 100
2015-03-03T15:09:00 < dongs> if you take out teh arduino there's < $15 there
2015-03-03T15:09:02 < jpa-> calculating from the $350 sale price
2015-03-03T15:09:03 < dongs> from the shit i can see on pcb
2015-03-03T15:09:28 < jpa-> what kind of sensor are they using?
2015-03-03T15:09:30 < dongs> some optoisolators, some passives (<40 of them cuz refdes ends tehre)
2015-03-03T15:09:37 < dongs> does it even need a sensor?
2015-03-03T15:09:50 < jpa-> i think i saw some sensor discussion somewhere
2015-03-03T15:09:59 < jpa-> it's supposed to sense when an event happens, anyway
2015-03-03T15:10:16 < jpa-> and maybe they also have the boxes on the BOM
2015-03-03T15:10:58 < BrainDamage> the boxes would have to be outrageously expensive to make up the price difference
2015-03-03T15:14:11 < jpa-> how so? $15 random crap + $15 atmega + $15 sensor + $55 boxes = $100 BOM, then add assembly, profit margin, resale channel etc. and you get the "we would have to *sell* them at $350"

2015-03-03T15:20:32 < BrainDamage> 50$ is pretty expensive for a box i'd say

2015-03-03T15:26:08 < jpa-> hmm, IMO on their site it seems like a totally custom box
2015-03-03T15:27:18 < jpa-> 3D printing such a box commercially would be easily $100, and i'm not sure what injection molding costs per unit at such quantities (they probably don't have the money for highly automatic part removal from the mold, so there would be manual work)
2015-03-03T15:28:20 < jpa-> protomold makes pretty cheap stuff, so not sure why they think that molds are $50k
2015-03-03T16:13:34 < Laurenceb> i just paid for some molds
2015-03-03T16:13:42 < Laurenceb> $30k
2015-03-03T16:13:59 < dongs> you dont need to pay for molds. just check out your room. surely to find some molded cheezburgers on the floor

2015-03-03T16:52:23 < emeb> I started my first stm32 project back in Aug 2011

2015-03-03T17:01:13 < karlp> yeah, seems I got the 32L because that was the low power cool I wanted, and I'd assumed stlink was going to work,
2015-03-03T17:01:30 < karlp> then bought the vl to work out what was different, and got them both to work,

2015-03-03T17:14:50 < emeb> environmental protection. bah.
2015-03-03T17:14:57 < emeb> shameless rationalization.
2015-03-03T17:15:40 < karlp> comments indicate that they've backtgracked on this since then...
2015-03-03T17:17:43 < emeb> it's a friggin' nuisance
2015-03-03T17:18:03 < karlp> kemet says, "These surface mount multilayer ceramic capacitors are
2015-03-03T17:18:03 < karlp> normally supplied unmarked. If required, they can be marked
2015-03-03T17:18:04 < karlp> as an extra cost option"
2015-03-03T17:18:20 < dongs> i've never seen a marked ceramic cap
2015-03-03T17:18:26 < dongs> do those e ven exist?
2015-03-03T17:20:07 < jpa-> sure, in through hole packages
2015-03-03T17:21:13 < emeb> heh
2015-03-03T17:21:56 < emeb> thing is most mlcc caps (most) are in square cross-section so there's no right-side up orientation.
2015-03-03T17:22:05 < emeb> which side would you mark?
2015-03-03T17:22:20 < dongs> well
2015-03-03T17:22:27 < dongs> resistors have up and down side too
2015-03-03T17:22:32 < dongs> yet they're in reels always black side up
2015-03-03T17:22:34 < dongs> so..
2015-03-03T17:22:41 < dongs> they must have a way to know before it goes into the reel
2015-03-03T17:22:59 < emeb> or I suppose they could mark them as they go in the tape.
2015-03-03T17:23:56 < emeb> some of the 2.2uf caps I use for the Vcap on F4 are thinner than they are wide.
2015-03-03T17:24:09 < dongs> emeb: what do you think about this rage-inducer
2015-03-03T17:24:09 < dongs> < dongs> 47nF caps are on digieky not under 47nF, not 47000pF, but under 0.047uF
2015-03-03T17:24:26 < emeb> I see that all the time
2015-03-03T17:24:35 < GargantuaSauce> i dont get why they arent all in base units
2015-03-03T17:24:35 < dongs> YET lower nF stuff shows up as xxx pF
2015-03-03T17:24:43 < dongs> consistently
2015-03-03T17:24:50 < dongs> but 47 is exception
2015-03-03T17:25:13 < emeb> it's annoying, but it's Digi-key. :P
2015-03-03T17:25:14 < dongs> GargantuaSauce: you mean 0.0047uF?
2015-03-03T17:25:24 < dongs> or like F
2015-03-03T17:25:25 < dongs> lol
2015-03-03T17:25:32 < dongs> 10E-10F
2015-03-03T17:25:35 < GargantuaSauce> yeah taht

2015-03-03T17:26:04 < GargantuaSauce> i mean it could certainly DISPLAY stuff with a sensible metric prefix
2015-03-03T17:26:25 < GargantuaSauce> but the database should have the value in base units so searching isn't such a pain
2015-03-03T17:26:34 < dongs> ah, right
2015-03-03T17:26:43 < emeb> just need a database that can do the right thing regardless of how the mfg or sales dept enter it.
2015-03-03T17:27:08 < scummos> 0.0047uF, really? who writes things like that
2015-03-03T17:27:08 < GargantuaSauce> yeah "just"
2015-03-03T17:27:28 < dongs> all i was trying to do was look for 47nF cap
2015-03-03T17:27:33 < emeb> it's so simple! :P
2015-03-03T17:27:38 < scummos> :D you found it
2015-03-03T17:27:47 < dongs> i have this http://www.justradios.com/uFnFpF.html bookmarked
2015-03-03T17:27:55 < dongs> so when I failed to find 47nF i went there and checked for otehr shit
2015-03-03T17:28:16 < scummos> a table for moving a comma in a number, nice
2015-03-03T17:28:23 < dongs> i'm not very smart

2015-03-03T17:40:48 < scummos> what else do you use except utf-8
2015-03-03T17:40:49 < dongs> that tarsh just breaks my terminal
2015-03-03T17:40:58 < dongs> scummos: unicode/utf16
2015-03-03T17:41:00 < GargantuaSauce> maybe you should use an os that doesn't suck
2015-03-03T17:41:03 < dongs> that doubles all your files
2015-03-03T17:41:12 < dongs> GargantuaSauce: i agree, lunix is garbage
2015-03-03T17:41:14 < scummos> utf-16 for file endocing doesn't make much sense imo
2015-03-03T17:41:56 < scummos> wait wait linux has utf-8 as default encoding for like ever
2015-03-03T17:42:09 < scummos> but I know another OS which still creates some iso-whatever crap files all the time ;P
2015-03-03T17:42:27 < emeb> that's great until you hit an app that expects plain text.
2015-03-03T17:42:41 < emeb> what? values > 127???
2015-03-03T17:43:09 < scummos> "plain text" does not exist
2015-03-03T17:43:39 < dongs> ur a plain text
2015-03-03T17:43:43 < scummos> it's an illusion that there is any agreement on what that word means
2015-03-03T17:44:06 < dongs> scummos: 99% of lunix apps will shit themselves when trying to open non-ascii filename

2015-03-03T17:54:36 < dongs> so their battlestations are like 386/16

2015-03-03T17:54:54 < gxti> lunix does more on a 386 than windows 8 does on a supercomputer amirite
2015-03-03T17:55:02 < dongs> ur wrong
2015-03-03T17:55:14 < dongs> cuz; latest lunix doesnt even run on a 386
2015-03-03T17:55:24 < dongs> and windows 8 runs on last ~10 years of computers
2015-03-03T17:55:53 < kakeman> just watching dave explaining dual cpu xeon mainboard
2015-03-03T17:56:06 < dongs> of course if by "does more" you mean sitting under your bed doing nothing (otehr than increasing your power bill and heating up the room) then sure

2015-03-03T17:57:16 < gxti> and then complained about them for 2 hours i bet
2015-03-03T17:57:16 < dongs> few months ago
2015-03-03T17:57:22 < dongs> he sure did

2015-03-03T17:57:36 < dongs> those were so old, throwing htem away was the best thing the business could have done
2015-03-03T17:57:43 < dongs> by buying new tech xeons tehy probly halved their power bill
2015-03-03T17:57:48 < dongs> and the shit would pay off in a few months

2015-03-03T18:04:42 < dongs> and what? also connect to SDIO on stm32?

2015-03-03T20:02:50 < Steffanx> better link to rickroll next time ReadError
2015-03-03T20:03:11 < ReadError> http://www.cs.indiana.edu/~geobrown/book.pdf
2015-03-03T20:03:15 < ReadError> that book is pretty decent
2015-03-03T20:03:32 < Galahan> ty ReadError :) I'll check it
2015-03-03T20:03:39 < Galahan> and with platform do you mean, board?
2015-03-03T20:03:47 < Galahan> GargantuaSauce?
2015-03-03T20:04:00 < GargantuaSauce> i mean the dev machine
2015-03-03T20:06:09 < Galahan> we are allowed to use Keil or CooCox at the course, and I use them under windows XP and 8
2015-03-03T20:06:32 < Galahan> I'm thinking on using coocox for what I've seen so far
2015-03-03T20:07:47 < Steffanx> Go keil. The compiler is superior
2015-03-03T20:09:13 < qyx_> why can't you choose?
2015-03-03T20:09:23 < qyx_> i mean other options
2015-03-03T20:09:40 < Galahan> We can choose xD Those are only the recommended compilers IDE by the professor
2015-03-03T20:09:46 < Galahan> we are free to use whatever we want+
2015-03-03T20:10:36 < Galahan> Asking as a newbie, it's a big gap between Keil and Coocox compiler for example?
2015-03-03T20:12:19 < Steffanx> No. It's gcc vs armcc. Anyway if you dont care about using a eclipse based IDE, use CoIDE

2015-03-03T20:12:36 < Steffanx> It's free.. ( keil is still free for 32k code? )
2015-03-03T20:13:04 < Galahan> yes, the license we have at class computers, and the one you can download
2015-03-03T20:13:21 < GargantuaSauce> oh yeah if you have a full license for keil use that
2015-03-03T20:13:50 < Galahan> we have the free license :D
2015-03-03T20:14:03 < qyx_> but if you get used to keil, you will either need to steal it or buy it

2015-03-03T20:40:48 < GargantuaSauce> maybe print the clock tree and peripheral/bus diagram
2015-03-03T20:43:46 < Galahan> guys you've been a grat help :)! I'm closing that , would check log at home and login again maybe with more doubts

2015-03-04T00:36:51 < Getty> ah those lovely new problems, changed the use concept of a variable and forgot to make it uint16_t instead of uint8_t cause the newer usage required values 256<.....
2015-03-04T00:36:59 < Getty> took me a while to realize my mistake.... ;)
2015-03-04T00:38:04 < specing> thats because you are using a crap language that is C
2015-03-04T00:38:20 < specing> if you used Ada or SPARK, your change wouldn't make it paste the type system
2015-03-04T00:39:25 < qyx_> Getty: disabled typecasting warnings again?
2015-03-04T00:39:39 < qyx_> -Wcast-equal -Werror
2015-03-04T00:39:40 < qyx_> there you go
2015-03-04T00:40:03 < specing> How many values do you need Getty?
2015-03-04T00:40:57 < Steffanx> specing still not over his C phobia?
2015-03-04T00:41:19 < qyx_> *qual
2015-03-04T00:41:46 < qyx_> and i am wrong again
2015-03-04T00:42:36 < qyx_> -Wconversion is the right one for this case
2015-03-04T00:42:39 < specing> Steffanx: I'm done with C

2015-03-04T00:48:01 < Getty> qyx_: out of the "supporting libs" i cant activate as much warning as i want, would it have noticed that the sizes are not fitting? must check this, right now i am happy that it works like i want
2015-03-04T00:48:06 < Getty> watching the cloud and rain simulation

2015-03-04T00:49:32 < Getty> this is insane...... the cloud coming going and the rain constantly.... the rain has a logic "Per LED" so they flickr independent, the clouds are "overall" so the cloud gives a unified lower brightness
2015-03-04T00:51:05 < qyx_> yes, it would force you to explicitly cast things if the result has different size
2015-03-04T00:51:53 < Getty> qyx: mh i think it would choke up on a lot of my code then, i mean i often put a u16 in a u32 or other around cause i know they never get into the sizes
2015-03-04T00:52:07 < Getty> (mostly its because functions gives back u32 but the expected value is for sure under u16)
2015-03-04T00:52:40 < Getty> so those all choke up?... oh dear and people wonder why C is not getting enough love 8-)
2015-03-04T00:53:36 < Getty> i already do now a LOT of casting if its about signed unsigned and float, like casting every single thing involved... super awesome :) thats good working

2015-03-04T01:15:02 < GargantuaSauce> also you may not have come across this but casting a float to an unsigned = danger
2015-03-04T01:16:02 < Getty> float => floor => unsigned, is my way
2015-03-04T01:16:06 < Getty> thats fine, or?! :)
2015-03-04T01:16:20 < specing> what if the float is INF?
2015-03-04T01:16:25 < specing> or NaN?
2015-03-04T01:16:26 < GargantuaSauce> are you using the hardware fpu
2015-03-04T01:16:34 < specing> or 10e100?
2015-03-04T01:16:43 < GargantuaSauce> i've produced hardfaults by doing that
2015-03-04T01:17:06 < Getty> and.. what should do i against? ;-) check every time? ;)
2015-03-04T01:17:29 < GargantuaSauce> irrespective of the sign actually
2015-03-04T01:18:02 < GargantuaSauce> maybe cast to signed first. or maybe if it doesnt break for you it doesnt matter i dunno
2015-03-04T01:20:38 < Getty> heheheh :)
2015-03-04T01:21:02 < Getty> GargantuaSauce: oh that feels so safe when the expert says something like that :) i feel so comfortable hehe
2015-03-04T01:21:33 < GargantuaSauce> who you callin' expert, punk
2015-03-04T01:21:56 < Getty> probably the guy who makes the first warp engine will be saying "well, the warp engine was easy, but when i was a young, i did C..... that was hard"
2015-03-04T01:22:36 < Getty> the point is, that i think with my enforcing of floor i am at least for sure in the right direction of the obvious method, i am really "scared" to just cast a float to something
2015-03-04T01:22:43 < Getty> and that fear is good ;)
2015-03-04T01:23:08 < qyx_> you are not scared enough if using floats
2015-03-04T01:23:21 < Getty> some i have to make sometimes a factor in math
2015-03-04T01:23:22 < Getty> :-/
2015-03-04T01:23:33 < Getty> i try to avoid! oh yeah i do try to avoid as much as possible

2015-03-04T01:42:45 < Laurenceb_> to send my own satellite up on a ego trip to space
2015-03-04T01:43:16 < Laurenceb_> or actually to launch an amateur satellite for epic win
2015-03-04T01:43:33 < kakeman> is there yet more serious alternatives for kickstarter?
2015-03-04T01:43:41 < kakeman> and more international
2015-03-04T01:43:47 < baird> Be the first tranwoman to send a satellite into space.
2015-03-04T01:44:05 < kakeman> kickstarter kind of tastes like boston - ny
2015-03-04T01:44:25 < Getty> kakeman: there is some european union supported technology kickstarter platform
2015-03-04T01:44:36 < Getty> kakeman: which only takes like a fifth of your money...............................
2015-03-04T01:46:01 < kakeman> that sounds like a deal
2015-03-04T01:47:07 < Getty> i am sure you find some who takes even more of you money! you should search them before you make the deal!
2015-03-04T01:47:12 < dongs> "more serious"
2015-03-04T01:47:53 < Getty> there is a free german platform
2015-03-04T01:48:21 < Getty> only hook is that you need to use a specific online bank, but thats actually not producing any cost or anything, just "different" as usual
2015-03-04T01:48:47 < Getty> but if you see the projects on there......... you actually cant imagine that this is a german platform... just horrible projects.... and not much cash flow overall
2015-03-04T01:49:31 < Getty> but you can make a campaign double language, so that there is an english and german page for your campaign, which is like a really awesome feature............. (which american companies never will offer)
2015-03-04T01:52:13 < kakeman> hmm finish crowdfunding site looks serious
2015-03-04T01:52:48 < kakeman> less iphone cables
2015-03-04T01:54:38 < kakeman> but too much restaurants and art performances :/

2015-03-04T07:26:33 < GargantuaSauce> i dont think theres a mechanical standard or anything for canbus
2015-03-04T07:28:09 < dongs> definitely not
2015-03-04T07:28:23 < dongs> you could jsut use RJ45

2015-03-04T07:28:30 < dongs> or whatever
2015-03-04T07:28:32 < dongs> phonewire shit
2015-03-04T07:28:36 < emeb_mac> what changed on your encoder?
2015-03-04T07:28:45 < dongs> emeb_mac:maybe iw as just stoned
2015-03-04T07:28:50 < dongs> i didnt see it working in keil tim3 peripheral window
2015-03-04T07:29:13 < emeb_mac> ah
2015-03-04T07:29:18 < dongs> but I added TIM3->CNT to watch
2015-03-04T07:29:33 < emeb_mac> using the timer encoder decoder?
2015-03-04T07:30:16 < dongs> ya
2015-03-04T07:30:20 < dongs> TIM3_CH1/2
2015-03-04T07:30:23 < emeb_mac> I tried that a while ago. for some reason it always counted by 2
2015-03-04T07:30:32 < dongs> it does, but who cares
2015-03-04T07:30:39 < dongs> it actualyl  counts 1 but you dont see it fast enough
2015-03-04T07:30:46 < dongs> on 'half click' it counts 1
2015-03-04T07:30:51 < emeb_mac> ic
2015-03-04T07:30:59 < dongs> if you got a clicky encoder
2015-03-04T07:30:59 < emeb_mac> wasn't just stoned
2015-03-04T07:31:07 < dongs> you can slowly move it between clicks
2015-03-04T07:31:10 < dongs> and you will see CNT being odd number
2015-03-04T07:31:17 < dongs> then when it clicks back, it'll be even again.
2015-03-04T07:31:24 < emeb_mac> free extra resolution
2015-03-04T07:31:28 < dongs> yeah
2015-03-04T07:32:09 < dongs> now to think how to do this

2015-03-04T08:46:13 < emeb_mac> all filters act as delays
2015-03-04T08:46:31 < dongs> i did that exponential knob thing
2015-03-04T08:46:43 < dongs> but its output goes to a PID that finally sets PWM value
2015-03-04T08:46:56 < dongs> so slow clicks, changing direction, and more slow clicks
2015-03-04T08:47:02 < dongs> takes about 5-6 clicks before it registers on PWM output
2015-03-04T08:47:12 < dongs> but once youre going in a direciton its ok.

2015-03-04T08:50:32 < emeb_mac> the integrator and runtime.pwm_value too
2015-03-04T08:50:58 < emeb_mac> that second integrator will cause some lag
2015-03-04T08:51:06 < dongs> oh.

2015-03-04T08:51:51 < jpa-> yeah, you have I,I^2 controller
2015-03-04T08:52:10 < emeb_mac> what's the pwm value driving?
2015-03-04T08:52:12 < jpa-> instead of PI which it tries to be, and PID which you think it is
2015-03-04T08:52:29 < dongs> just directly goes to CCR1
2015-03-04T08:52:31 < dongs> last line
2015-03-04T08:52:44 < jpa-> he means, what is the hardware you are controlling?
2015-03-04T08:52:48 < jpa-> err
2015-03-04T08:52:51 < emeb_mac> right, but what's that PWM signal hooked to?
2015-03-04T08:53:00 < jpa-> your feedback signal is the pwm_value?
2015-03-04T08:53:02 < dongs> oh just a led brightness
2015-03-04T08:53:06 < jpa-> why would you do this?
2015-03-04T08:53:15 < jpa-> why not just    pwm_value = pwm_setpoint?
2015-03-04T08:53:16 < emeb_mac> yeah, that.
2015-03-04T08:53:23 < dongs> um
2015-03-04T08:53:35 < dongs> so its stretched over period instead of fast jump
2015-03-04T08:53:39 < emeb_mac> oh.
2015-03-04T08:53:46 < emeb_mac> just smoothing the change
2015-03-04T08:53:50 < jpa-> then do   pwm_value = pwm_value * 0.9 + pwm_setpoint * 0.1
2015-03-04T08:54:01 < dongs> that doesnt look good tho
2015-03-04T08:54:02 < emeb_mac> simple 1st-order IIR
2015-03-04T08:54:11 < Getty> <facepalm>..... fabs... not abs...... <facepalm>
2015-03-04T08:54:39 < dongs> Getty: i know, i am not worried about 20k of code being added to firmweare
2015-03-04T08:54:56 < Getty> hu?
2015-03-04T08:55:01 < Getty> oh we are at LED brightness
2015-03-04T08:55:04 < Getty> my comment was unrelated ;)
2015-03-04T08:55:28 < jpa-> dongs: in what way doesn't it look good?
2015-03-04T08:55:39 < dongs> jpa, not sure, ill try in 10min need to post stuff
2015-03-04T08:55:50 < jpa-> though if you want slow start, slow stop, then you'll end with something PID like
2015-03-04T08:56:24 < jpa-> like  static float speed;  speed += (pwm_setpoint - pwm_value) * 0.1    pwm_value += speed;
2015-03-04T08:57:13 < jpa-> though that will overshoot

2015-03-04T09:00:11 < emeb_mac> could just do linear interpolation!
2015-03-04T09:00:12 < Getty> its the Gamma Correction but jut for steps, missing the time component
2015-03-04T09:00:53 < Getty> i dont know what dongs wanna have as "look good" ;) so i throw options at him to get something he likes ;)
2015-03-04T09:01:19 < jpa-> hmm yeah, gamma correction might be one of the things he is doing wrong
2015-03-04T09:01:30 < jpa-> but i think he wants to have a smooth change when someone turns the knob
2015-03-04T09:01:53 < Getty> whatever it is he wants, the topic is totally annoying and so any data information can help
2015-03-04T09:02:05 < Getty> in the end its a pure subjective opinion, nothing is right
2015-03-04T09:02:22 < jpa-> because in this age of internet, lack of information is the problem and just throwing more random links will solve every problem!
2015-03-04T09:02:38 < Getty> well thats a link he might not find as its coming from a german blog about the topic
2015-03-04T09:02:57 < Getty> its the first one coming up if you search for "mikrocontroller led fading" if you search as german
2015-03-04T09:03:03 < Getty> i doubt taht comes up in china ;)
2015-03-04T09:04:08 < Getty> and i remember dongs talking about excel sheets! ;) so it just ..... fitting to serve more pain on that level

2015-03-04T09:04:43 < emeb_mac> dongs: what happens if you replace line 12 with runtime.pwm_value = runtime.pid_output
2015-03-04T09:05:00 < emeb_mac> get rid of that 2nd integration...
2015-03-04T09:09:47 < dongs> lets see

2015-03-04T09:16:10 < dongs> and it pisses me off
2015-03-04T09:17:32 < jpa-> apparently it is some magic formula for gamma correction that Getty considers the best in the world - wait, there is more, three formulas!
2015-03-04T09:17:58 < jpa-> i agree that you probably want gamma correction, but simple x*x is typically close enough

2015-03-04T10:44:00 < bilboquet_> no just send a signal to wake up
2015-03-04T10:44:41 < _Sync_> then you got to have external circuits to shut it down, consuming more power overall
2015-03-04T10:45:56 < dongs> you can be in USB suspend
2015-03-04T10:46:07 < dongs> the power draw for that is documented in stm32 datasheet.
2015-03-04T10:46:17 < dongs> you can have it toggle some gpio that turns on more/other regulators for the system power.
2015-03-04T10:46:59 < dongs> its not going t o be zero tho
2015-03-04T10:47:09 < dongs> but if youre connected to usb why arent you using 5V from usb?

2015-03-04T11:41:37 < karlp> why are there three different drawing mode (opengl, cairo and default) and why would you need to switch betweent hem often enough that they have single key shortcuts?!

2015-03-04T11:45:58 < scummos> i mean they really have to finish this opengl canvas thing and make it the default and remove the others
2015-03-04T11:46:30 < scummos> it's ridiculous that the push'n'shove-routing only works in opengl but deleting parts of tracks only works in native so I have to switch between them

2015-03-04T11:49:20 < scummos> you can also use stronger words

2015-03-04T11:49:54 < jpa-> i guess they are moving to the opengl, but haven't finished it yet

2015-03-05T00:44:32 < Laurenceb_> not hardware wise, but management wise, yes
2015-03-05T00:47:10 < Laurenceb_> also it can literally be done with a si446x

2015-03-05T01:11:15 < englishman> dark side of the moon
2015-03-05T01:11:36 < scummos> 142? what's that? 300K is -174
2015-03-05T01:11:43 < scummos> dBm/Hz that is
2015-03-05T01:12:00 < BrainDamage> if you have stupidly low bandwith, you can have low integrated noise power
2015-03-05T01:12:00 < scummos> also, if you look at the sky you get a lower noise floor than the -174
2015-03-05T01:12:05 < BrainDamage> which is why the low sped
2015-03-05T01:12:20 < BrainDamage> yes, having lower temp = lower thermal noise

2015-03-05T01:27:50 < karlp> you write whatever you want to ITM_xxx ports in your code, then you need openocd or similar to enable and turn on the output (or do it all manually in your own code like jpa does) and then you need something that can read it

2015-03-05T13:07:35 < jpa-> per my 100% huge experience, pulseview is actually more user friendly than saleae software :)

2015-03-05T13:07:45 < jpa-> it doesn't work on my work windows
2015-03-05T13:07:48 < dongs> saleae software is pure shit
2015-03-05T13:07:57 < dongs> so being better than it is not hard
2015-03-05T13:08:07 < jpa-> what is the best logic analyzer sw you know?
2015-03-05T13:08:27 < dongs> well, i really like the stuff that comes with my pokemon analyzer
2015-03-05T13:08:59 < dongs> ive tried saleae a couple times, it was trash
2015-03-05T13:09:07 < dongs> i think i used OLS or whatever at some point
2015-03-05T13:09:09 < dongs> or tried to use
2015-03-05T13:09:15 < dongs> that was also horrible shit
2015-03-05T13:09:18 < dongs> no
2015-03-05T13:09:20 < dongs> SUMP or something
2015-03-05T13:09:20 < dongs> whatever
2015-03-05T13:09:43 < jadew> my client for the OLS was decent
2015-03-05T13:10:07 < jadew> not supporting it anymore tho as I'm planning to come up with a LA of my own this year
2015-03-05T13:10:43 < jpa-> what'll be the specs?
2015-03-05T13:11:09 < jadew> at the moment I'm thinking about something like 400 MSps
2015-03-05T13:11:30 < jadew> 16 Mb+ of buffer memory, but not sure yet how much and in what configuration
2015-03-05T13:11:38 < dongs> silly
2015-03-05T13:11:42 < dongs> go for something wiht ddr3
2015-03-05T13:11:43 < jpa-> hopefully transition encoded?
2015-03-05T13:11:45 < dongs> and like half a gig
2015-03-05T13:12:08 < jadew> dongs, I'm not sure yet on the memory part
2015-03-05T13:12:16 < jpa-> and what connection to pc?
2015-03-05T13:12:28 < jadew> jpa-, USB3
2015-03-05T13:12:42 < jpa-> yep, 16MB of fast sram might be reasonable then
2015-03-05T13:12:55 < jpa-> will it be open or closed sores?
2015-03-05T13:13:06 < jadew> closed
2015-03-05T13:13:26 < jadew> the specs are not set in stone, but yeah, SRAM would be ideal since with DRAM doing ring buffers is a bit of a PITA
2015-03-05T13:14:44 < jadew> anyway, I'll start work on it after I'm done with my current project so it's gonna be a while until it's ready

2015-03-05T13:16:33 < jpa-> will the protocol atleast be open?
2015-03-05T13:17:09 < jpa-> because closed LA software always lacks decoders
2015-03-05T13:17:10 < jadew> only by SDK, I don't want to be in the same shoes as saleae
2015-03-05T13:17:19 < jadew> jpa-, mine will rock
2015-03-05T13:17:24 < jpa-> it will still lack decoders
2015-03-05T13:17:33 < jadew> they will be easy to write
2015-03-05T13:17:42 < jpa-> not for complex protocols
2015-03-05T13:17:53 < jadew> I'll cover those
2015-03-05T13:18:13 < jpa-> no you won't, not all of them
2015-03-05T13:18:16 < jadew> I have a bunch of interesting plans for it
2015-03-05T13:18:34 < jpa-> besides, for verifying HW identity, you can simply have some crypto block on the FPGA - you can still support open source SW for it just fine
2015-03-05T13:19:05 < dongs> ATSHA204
2015-03-05T13:19:27 < jadew> jpa-, I suppose you're right, but you seem to have a lot of faith in opensource software
2015-03-05T13:19:29 < jpa-> saleae had its troubles because they just stick an FX2 on PCB and expect to charge $200 for it
2015-03-05T13:19:40 < dongs> they still do
2015-03-05T13:19:57 < jpa-> jadew: it works for me, no closed source software had the feature i needed and I don't feel like contributing to closed sores software by writing my own decoders
2015-03-05T13:20:00 < dongs> for $200 i expect amazesoftware
2015-03-05T13:20:14 < jpa-> dongs: the newer saleaes are a bit more complex in HW
2015-03-05T13:20:26 < jpa-> i bet they also have a better way of verifying HW autheticity
2015-03-05T13:20:28 < jadew> jpa-, my closed source LA client kicks ass
2015-03-05T13:20:29 < dongs> yeah ive seen them but they're still pretty shit
2015-03-05T13:20:34 < jadew> took me only a month to make
2015-03-05T13:20:43 < jpa-> jadew: and it decodes ARM ETMv3?
2015-03-05T13:20:56 < jadew> jpa-, no, but that's a different story
2015-03-05T13:21:09 < jpa-> yes, so i might buy your LA, but only if sigrok support can be made
2015-03-05T13:21:12 < jadew> doesn't really qualify as a feature
2015-03-05T13:21:35 < jadew> that's good input
2015-03-05T13:21:53 < jpa-> i've been wanting >400MSps logic analyzer with transition encoding and USB3
2015-03-05T13:22:05 < jpa-> preferrably with freely configurable sample rate (i.e. PLL, not just divider)
2015-03-05T13:22:24 < dongs> lets do it and ruin jadew's dickstarter plans
2015-03-05T13:22:24 < jpa-> so that if i have a signal at 133 MHz, i can sample at 399 MHz
2015-03-05T13:22:41 < jadew> dongs, I don't think I'll dickstart it
2015-03-05T13:23:15 < jadew> jpa-, I know what you mean, my previous project that failed had a very flexible clocking scheme
2015-03-05T13:23:32 < jadew> was able to get any baudrate within less than 0.2%
2015-03-05T13:23:46 < jpa-> i've been wondering if the FPGA serdes tranceivers could be used for >1GHz sampling

2015-03-05T13:29:23 < jadew> wanna bet that you'll want to kill yourself if you try to improve it?
2015-03-05T13:29:24 < karlp> I'd like to second jpa's claim that a good LA hardware might be nice, but no way I'm goign to relyon windows software and vendor supplied decoders
2015-03-05T13:29:58 < Tectu> hey jadew, how is your project going?
2015-03-05T13:30:01 < jpa-> jadew: i want to kill myself anyway, so i don't think that is a good datapoint
2015-03-05T13:30:07 < jadew> Tectu, which one?
2015-03-05T13:30:14 < jadew> jpa-, hehe
2015-03-05T13:30:24 < Tectu> jadew, the one you put on tindie once
2015-03-05T13:30:38 < jadew> Tectu, I didn't put anything on tindie, but proto-talk has failed
2015-03-05T13:30:48 < jpa-> never seen good docking windows on any platform, though
2015-03-05T13:30:49 < jadew> well, it's working and all, but didn't took off
2015-03-05T13:30:57 < jpa-> visual studio comes close, but still pretty crappy
2015-03-05T13:30:57 < jadew> jpa-, VS has it
2015-03-05T13:31:08 < jadew> my LA software has it
2015-03-05T13:31:22 < jpa-> the same as VS? yeah, works, not awesome
2015-03-05T13:31:23 < jadew> same behavior with VS
2015-03-05T13:31:47 < jpa-> the docking in e.g. kdevelop is IMO atleast as good as VS
2015-03-05T13:31:54 < jpa-> not sure if that is some KDE extra or plain qt
2015-03-05T13:31:59 < jadew> haven't used kdevelop in a while
2015-03-05T13:32:00 < jpa-> or custom
2015-03-05T13:32:44 < Tectu> jadew, sad :(
2015-03-05T13:32:55 < jadew> anyway, Qt is nice and all, but it's limitting for me
2015-03-05T13:33:01 < jpa-> the pulseview gui is pretty nice in that there is not much crap you need to care about, no need to arrange dockable windows etc. which is not really the task you are interested in
2015-03-05T13:33:22 < jadew> I said that before, I'd rather make kickass software for one platform than offer a mediocre experience for all of them
2015-03-05T13:33:34 < jpa-> yeah, i know, that is a fine attitude
2015-03-05T13:33:43 < jpa-> just limits your market, especially if you aim for the hobbyists
2015-03-05T13:33:50 < dongs> uh bro
2015-03-05T13:33:59 < jadew> I know, it's not an easy decision
2015-03-05T13:34:01 < dongs> real pro hobbyists al use windows
2015-03-05T13:34:13 < jpa-> i know, i'm just hobby hobbyist after all
2015-03-05T13:34:19 < dongs> lunix dudes are just parents basement dwellers
2015-03-05T13:34:27 < dongs> they wont pay for your software/hardware anyway
2015-03-05T13:34:29 < dongs> they will demand free shit
2015-03-05T13:34:46 < jpa-> rarely they demand free hw :)
2015-03-05T13:34:51 < jadew> yeah
2015-03-05T13:34:58 < jadew> in this case this would be a no-issue really
2015-03-05T13:35:10 < jpa-> but yeah, sigrok support + proprietary windows sw might be a good combination
2015-03-05T13:35:14 < jadew> since the software is going to be free anyway
2015-03-05T13:35:27 < karlp> that would be fine, yeah
2015-03-05T13:35:35 < dongs> jpa, you hack on smoothie?
2015-03-05T13:35:39 < jadew> sounds good to me too
2015-03-05T13:35:49 < karlp> if the hardware provided some advantages vs other hardware that already had support in sigrok...
2015-03-05T13:35:50 < jpa-> dongs: only because i bought that crap
2015-03-05T13:36:03 < jpa-> linuxcnc would've been better
2015-03-05T13:36:34 < jpa-> karlp: yeah, though if it is cheap enough (100-200 EUR) and samples at 400MSps, then it would be worth it
2015-03-05T13:37:45 < jadew> jpa, that's pretty much the target (including the price range)
2015-03-05T13:38:22 < jadew> I'm working on something else at the moment tho, I needed a break from the digital stuff

2015-03-05T15:40:18 < dongs> and blow it up
2015-03-05T15:45:25 < trepidaciousMBR> Why did ST decide that the L6470 would need a CS pulse after every byte of SPI comms?

2015-03-05T15:46:04 < trepidaciousMBR> I bet they saved at least $0.0000001 per chip doing that, shame it makes it impossible to talk to unless you have "NSS pulse" on your MCU

2015-03-05T15:50:55 < GargantuaSauce> thats how hardware nss works on the stm32 spi peripherals isnt it
2015-03-05T15:51:03 < GargantuaSauce> maybe it's some "subtle" vendor lock-in
2015-03-05T15:51:08 < trepidaciousMBR> Yup :(
2015-03-05T15:51:26 < trepidaciousMBR> GargantuaSauce I think they only do that when you have "NSS_PULSE" set in SPI CR2, which is only on some chips...
2015-03-05T15:52:14 < GargantuaSauce> huh
2015-03-05T15:52:25 < jpa-> i wonder why the diagram on page 39 shows it transferring multiple bytes before CS pulse
2015-03-05T15:52:47 < jpa-> so more like after every command than after every byte

2015-03-05T16:00:48 < GargantuaSauce> that looks like a pretty sweet driver, quirks notwithstanding
2015-03-05T16:06:53 < dongs> After each byte transmission the CS input must be raised and be kept high for at least tdisCS
2015-03-05T16:06:57 < dongs> in order to allow the device to decode the received command and put the return value into
2015-03-05T16:07:00 < dongs> the SHIFT register
2015-03-05T16:07:02 < dongs> wow wat

2015-03-05T16:07:54 < dongs> ok the diagram below shows it toggles CS after each command

2015-03-05T16:08:59 < dongs> hmmmmmmmmm
2015-03-05T16:09:10 < dongs> picture on NEXT page shows CS toggling after sending some bytes
2015-03-05T16:09:51 < dongs> ah, i see why they did it
2015-03-05T16:09:55 < dongs> for daisy chaining
2015-03-05T16:10:13 < dongs> so when you have say 4 of htem, you send 4 command bytes tehn toggle CS
2015-03-05T16:10:29 < dongs> it shifts out each byte losing one in process (in the current chip) and finally the last chip gets it
2015-03-05T16:10:52 < dongs> each one in series onyl sees one CS toggle and one byte of data.
2015-03-05T16:11:04 < dongs> shitty that you have t o manually toggle but makes sense why it was done.
2015-03-05T16:11:12 < Steffanx> yeah, that makes sense
2015-03-05T16:12:29 < trepidaciousMBR> dongs: Ah right, well at least there's a reason then

2015-03-05T16:42:00 < Laurenceb> time to get a saleae on it too see why it locks up

2015-03-05T16:44:35 < Laurenceb> anyone know if kapton tape transmits IR?
2015-03-05T16:44:51 < emeb> I know a fun way to find out
2015-03-05T16:44:55 < Laurenceb> need something to cover the front
2015-03-05T16:44:56 < Laurenceb> lol
2015-03-05T16:44:58 < GargantuaSauce> just stick it on a remote control or something
2015-03-05T16:44:59 < emeb> also, what wavelength
2015-03-05T16:45:01 < GargantuaSauce> and see if it works
2015-03-05T16:45:11 < Laurenceb> 850nm
2015-03-05T16:45:11 < emeb> +1
2015-03-05T16:45:20 < jpa-> or look with camera
2015-03-05T16:45:28 < Laurenceb> good idea
2015-03-05T16:45:39 < GargantuaSauce> oh 850 is reallly near, i cant see it blocking that
2015-03-05T16:45:46 < emeb> well, a camera that doesn't have an IR filter
2015-03-05T16:45:50 < emeb> many do
2015-03-05T16:46:00 < jpa-> most still show IR
2015-03-05T16:46:07 < jpa-> even though they filter out the most of it
2015-03-05T16:46:46 < BrainDamage> you can also stick a strong emitter and just look at the time it takes to melt it trough

2015-03-05T17:29:55 < GargantuaSauce> it kind of bothers me that there's a voltage in the function name

2015-03-05T17:31:31 < rkreis_> looks like the clock system is a bit more complicated than i thought
2015-03-05T17:32:15 < GargantuaSauce> i think the library has macros or something for doing the work for you, i am not familiar with it though
2015-03-05T17:32:18 < zyp> it's not very complicated to use if your needs are simple
2015-03-05T17:32:33 < GargantuaSauce> otherwise just consult the clock tree in the reference manual
2015-03-05T17:33:22 < rkreis_> which reference manual would i be looking at? cortex m3, or is it specific to the stm32f1?
2015-03-05T17:33:31 < zyp> there should be a simple function to handle the common situation where you have an 8MHz crystal and want the cpu to run at full speed

2015-03-05T17:36:18 < rkreis_> just found void rcc_clock_setup_in_hse_12mhz_out_72mhz
2015-03-05T17:36:39 < rkreis_> now, i better look up with hsi and hse are

2015-03-05T17:40:58 < rkreis_> i figured the stm32f107_usb_driver should work, well, it gets stuck while initializing

2015-03-05T17:42:56 < rkreis_> seeing if the clock was right was my first and only idea, but if it uses the hsi, nothing can go wrong, i guess?
2015-03-05T17:46:39 < GargantuaSauce> well the hsi in that line isn't stable enough for usb but i dont think that has anything to do with your particular problem

2015-03-05T17:57:15 < dongs> not surprised here
2015-03-05T17:57:42 < rkreis_> the libopencm3 example...
2015-03-05T17:57:46 < GargantuaSauce> libopencm3 examples actually....and not super surprising there either
2015-03-05T17:58:21 < rkreis_> well, the blinking led worked... :)
2015-03-05T17:59:10 < rkreis_> so, uh, it also sets AFIO_MAPR_SWJ_CFG_JTAG_OFF_SW_ON which makes me hope i'm actually debugging over SWD (how would i know?)
2015-03-05T17:59:36 < GargantuaSauce> well if you can debug at all it's set correctly i guess
2015-03-05T17:59:52 < karlp> what example are you looking at? and on what board?

2015-03-05T18:03:53 < karlp> yes, that's why libopencm3 has two different ones, so which one does the f105 have?
2015-03-05T18:04:04 < dongs> 107 one

2015-03-05T22:48:53 < Steffanx> pcb design failure?
2015-03-05T22:49:17 < Laurenceb_> heh
2015-03-05T22:49:19 < Laurenceb_> maybe
2015-03-05T22:49:39 < Laurenceb_> i needed to stick decoupling on the other side of the board to mount the optics on the front
2015-03-05T22:49:46 < _Sync_> well it will consume power pulsed like a mofo
2015-03-05T22:49:49 < Laurenceb_> maybe too much inductance in the vias
2015-03-05T22:50:07 < Laurenceb_> that doesnt explain why i get BERR on the I2C
2015-03-05T22:50:31 < Laurenceb_> going to try to find a very fast scope tomorrow to take a look
2015-03-05T22:51:42 < Laurenceb_> maybe a few pF to ground from the i2c on the sensor board

2015-03-05T23:00:02 < kakeman> on display fingerprint sensing
2015-03-05T23:01:21 < Steffanx> its not in the display it's in the "home button"
2015-03-05T23:03:51 < kakeman> thats a bit meh
2015-03-05T23:04:11 < kakeman> i supposed it' display surface at any point
2015-03-05T23:04:47 < BrainDamage> there's a gigantic resolution difference between the touchscreen capacitive sensor and the fingerprint sensor
2015-03-05T23:04:59 < kakeman> certainly
2015-03-05T23:09:35 < _Sync_> still useless
2015-03-05T23:17:34 < Laurenceb_> hmm
2015-03-05T23:17:46 < Laurenceb_> i wonder if this is the sort of thing thats going on with my VL6180X
2015-03-05T23:18:00 < Laurenceb_> no BERR until I stick my finger close to it
2015-03-05T23:18:40 < Laurenceb_> cant see anything bad on my saleae, I'm guessing its very sharp pulses due to capacitive coupling from the laser firing
2015-03-05T23:20:07 < _Sync_> I guess you need a fast scope to find that
2015-03-05T23:20:49 < Laurenceb_> yeah
2015-03-05T23:21:03 < Laurenceb_> its a nanosecond timescale rise time
2015-03-05T23:23:28 < kakeman> https://drive.google.com/file/d/0B2GcdpJiNGfKc2UzX1pDS2VvNDg/view?usp=sharing how to read this

2015-03-05T23:24:42 < _Sync_> ns risetime is not too bad
2015-03-05T23:37:42 < kakeman> if you have hex with 0x0000 0000 eight digits does that signal you would be using unsigned long there?

2015-03-05T23:43:48 < Laurenceb_> hmf
2015-03-05T23:43:59 < emeb> What does Shannon know - he's dead.
2015-03-05T23:44:05 < Laurenceb_> maybe a 2-PSK link is needed
2015-03-05T23:44:12 < kakeman> you always need to see that someone can do it better, faster, harder
2015-03-05T23:44:17 < Laurenceb_> I guess this is the same problem balloons face
2015-03-05T23:44:29 < Laurenceb_> Shannon says you need <<1bit/Hz
2015-03-05T23:44:36 < Laurenceb_> how do you modulate that
2015-03-05T23:44:48 < Laurenceb_> i guess you could use 2PSK with lots of FEC
2015-03-05T23:45:30 < Laurenceb_> also I was thinking of making it capable of positioning
2015-03-05T23:45:36 < Laurenceb_> tricky :S
2015-03-05T23:46:59 < Laurenceb_> most coding schemes are bandwidth constrained
2015-03-05T23:48:16 < emeb> true, buy what's the relevance to positioning?
2015-03-05T23:48:25 < emeb> s/buy/but/
2015-03-05T23:48:42 < Laurenceb_> no need for GPS
2015-03-05T23:49:02 < Laurenceb_> I guess with latest SiRF its less important
2015-03-05T23:49:29 < Laurenceb_> thats down to 1mW for trickle power mode
2015-03-05T23:49:39 < Laurenceb_> actually thats still a lot of power
2015-03-05T23:50:41 < Laurenceb_> sat uplink would use 6mW for 10 minutes twice a day
2015-03-05T23:55:22 < Laurenceb_> "One of the problems with such a small satellite is the limited amount of power that can be generated"
2015-03-05T23:55:42 < Laurenceb_> erm thats also a problem on the ground if you want telemetry from anything interesting
2015-03-05T23:57:41 < _Sync_> fucking cover it in soler cells
2015-03-05T23:57:58 < _Sync_> suck it up and buy triple layer cells

2015-03-06T01:31:57 < Laurenceb_> sell them on ebay
2015-03-06T01:35:51 < emeb> Laurenceb_: doesn't STM32 have a part with some sort of high-res timer function?
2015-03-06T01:36:46 < emeb> F334 - 200ps resolution...
2015-03-06T01:41:23 < Laurenceb_> its not real
2015-03-06T01:41:43 < Laurenceb_> its all fake with multiple interleaved times and jitter
2015-03-06T01:44:02 < _Sync_> it works fairly well
2015-03-06T01:44:12 < _Sync_> it has not actual 200ps resolution, but average it works out
2015-03-06T01:44:59 < emeb> _Sync_: you've used it?
2015-03-06T01:45:22 < _Sync_> yes
2015-03-06T01:45:37 < emeb> cool
2015-03-06T01:46:14 < Laurenceb_> yeah 200ps would be awesome for LiDAR
2015-03-06T01:46:15 < emeb> So it looks like the HRTIM works by doing 32 sub-phases of a 144MHz clock, then triggering WRT those on output.
2015-03-06T01:46:31 < emeb> can it also capture those on input?
2015-03-06T01:46:53 < emeb> hard to tell from the docs due to hand-wavy terminology...
2015-03-06T01:47:23 < _Sync_> yeah the docs for the hrtim are ass
2015-03-06T01:47:32 < _Sync_> I had to reverse the stm32cube shit for it
2015-03-06T01:48:01 < emeb> my application is 2 10MHz clocks with variable phase offset
2015-03-06T01:48:32 < emeb> want to measure that phase as accurately as possible w/o using crazy hardware.
2015-03-06T01:48:46 < emeb> wondering if an F334 could give me like 1ns resolution or so.
2015-03-06T01:49:03 < _Sync_> that's actually a good question
2015-03-06T01:49:08 < emeb> phase is fairly stable so averaging measurements is OK
2015-03-06T01:49:14 < _Sync_> you'd have to figure out general clock jitter
2015-03-06T01:49:22 < Laurenceb_> it cant do capture
2015-03-06T01:49:28 < Laurenceb_> so useless for LiDAR :(
2015-03-06T01:49:31 < _Sync_> yeah
2015-03-06T01:49:36 < _Sync_> unfortunately
2015-03-06T01:49:48 < _Sync_> but can't you halt it and read the value?
2015-03-06T01:49:54 < Laurenceb_> no
2015-03-06T01:49:55 < _Sync_> oh wait, no
2015-03-06T01:50:04 < _Sync_> yeah that's a bit dumb
2015-03-06T01:50:11 < emeb> Laurenceb_: huh - docs say it can measure timing, but it's not clear what the res is.
2015-03-06T01:50:20 < Laurenceb_> I was trying to order some sensl SPADs, but they wont ship me the right parts :-/
2015-03-06T01:50:27 < Laurenceb_> emeb: only at 144mhz
2015-03-06T01:50:33 < _Sync_> 0o why not?
2015-03-06T01:50:42 < emeb> Laurenceb_: aha
2015-03-06T01:50:50 < _Sync_> I got some time to frequency things with ps resolution
2015-03-06T01:50:50 < emeb> not useful

2015-03-06T01:51:59 < _Sync_> how are they in spectral resolution?
2015-03-06T01:52:07 < Laurenceb_> not good
2015-03-06T01:52:11 < Laurenceb_> I wanted the M series

2015-03-06T01:52:37 < Laurenceb_> they referred me to their UK supplier, who dont answer emails :S
2015-03-06T01:52:43 < _Sync_> ok no use then
2015-03-06T01:52:51 < Laurenceb_> they are very epic
2015-03-06T01:52:57 < Laurenceb_> I'm going to keep pestering
2015-03-06T01:54:12 < _Sync_> well I'd like some replacement for pmts in gamma spectrum measurement
2015-03-06T01:54:21 < Laurenceb_> ah
2015-03-06T01:54:43 < Laurenceb_> whats the scintillator spectral output?
2015-03-06T01:55:07 < _Sync_> depends on the material
2015-03-06T01:55:20 < _Sync_> but I think it is around 500-550nm
2015-03-06T01:55:47 < Laurenceb_> ah then the C series will work quite well
2015-03-06T01:56:01 < Laurenceb_> I'm doing near infrared spectroscopy of tissue
2015-03-06T01:56:23 < _Sync_> hmm
2015-03-06T01:56:37 < _Sync_> how spendy are they
2015-03-06T01:56:39 < Laurenceb_> using the VL6180X at the moment
2015-03-06T01:56:44 < Laurenceb_>  <$100 each
2015-03-06T01:56:55 < Laurenceb_> so ~0 on the scale of this stuff
2015-03-06T01:57:06 < Laurenceb_> we are spending $100k on picoquant kit
2015-03-06T01:57:32 < _Sync_> hm yeah
2015-03-06T01:58:39 < _Sync_> I guess there is still a reason a lot of the gamma spectroscopy things use pmts
2015-03-06T01:59:54 < Laurenceb_> I cant think of it :P
2015-03-06T02:00:06 < Laurenceb_> SPADs are <30V and SMD
2015-03-06T02:01:34 < _Sync_> well, maybe the energy resolution sucks
2015-03-06T02:03:31 < BrainDamage> generally the noise of the SPADs and PMT are the same
2015-03-06T02:03:52 < BrainDamage> except ads active area is few um^2, and PMT few cm^2 ...
2015-03-06T02:04:08 < BrainDamage> apds*
2015-03-06T02:04:44 < BrainDamage> so the specific detectivity kinda sucks
2015-03-06T02:05:51 < _Sync_> yeah you gotta have an array

2015-03-06T02:10:40 < Laurenceb_> actually why does the energy resolution suck?
2015-03-06T02:18:42 < BrainDamage> SPADS have sources of correlated noise
2015-03-06T02:18:50 < BrainDamage> such as afterpulsing effects

2015-03-06T02:37:12 < emeb> Laurenceb_: any idea how those cheapo lidars from Sparkfun work?
2015-03-06T02:37:30 < emeb> hard to believe that they've got ps-level timing measurements in those little pkgs.
2015-03-06T02:38:43 < emeb> aha - correlation.
2015-03-06T02:39:37 < emeb> that requires integration and allows averaging adjacent measurements to estimate a peak.
2015-03-06T02:39:54 < emeb> so phase steps can be somewhat coarse
2015-03-06T02:41:03 < emeb> +/-25mm accuracy - 1inch
2015-03-06T02:42:31 < Laurenceb_> yeah
2015-03-06T02:42:38 < Laurenceb_> someone has done that with stm32f4
2015-03-06T02:42:56 < Laurenceb_> you can get reasonable accuracy over meter level ranges with phase
2015-03-06T02:43:14 < Laurenceb_> doesnt really work with tissue stuff due to the small paths
2015-03-06T02:43:29 < Laurenceb_> looks like I'm saturating my VL6180X, very unexpected
2015-03-06T02:43:42 < Laurenceb_> tissue attenuation is very low at 850nm
2015-03-06T02:47:44 < Laurenceb_> I'm tempted to epoxy on some 500µm multimode fibres
2015-03-06T02:48:00 < Laurenceb_> as long as they are less than 100mm each it should work fine
2015-03-06T02:48:03 < Laurenceb_> unless...
2015-03-06T02:48:18 < Laurenceb_> the VCSEL pulses every 10ns, so i could have a delay coil

2015-03-06T05:09:54 < dongs> dat price
2015-03-06T05:10:00 < qyx_> i would assume the security system pings the remote location periodically and if the signal goes off it triggers alarm
2015-03-06T05:10:19 < dongs> you'd think so
2015-03-06T05:10:23 < dongs> but no, im pretty sure its the other way around
2015-03-06T05:10:29 < dongs> its a gsm thingy wiht simcard
2015-03-06T05:10:33 < GargantuaSauce> no it'd be a drop-in replacement for a phone line calling in to a security company
2015-03-06T05:10:34 < dongs> that sends a text when stuff triggers
2015-03-06T05:10:34 < qyx_> and not the other way around like "uh, alarm, send a sms now!"
2015-03-06T05:10:45 < dongs> no, thats what it does exactly
2015-03-06T05:10:50 < qyx_> uhm
2015-03-06T05:11:05 < qyx_> so the "i am just dumb" applies probably
2015-03-06T05:11:12 < GargantuaSauce> just because that's dumb doesn't mean that's not how it works
2015-03-06T05:11:37 < GargantuaSauce> go read cybergibbons' blog, he's done analysis on a couple modern home security systems iirc
2015-03-06T05:11:41 < GargantuaSauce> and that is the least of their worries

2015-03-06T06:43:06 < GargantuaSauce> still makes me sick though
2015-03-06T06:48:29 < dongs> hurry up and click the like button
2015-03-06T06:48:31 < dongs> then youll feel less  sick
2015-03-06T07:08:27 < englishman> R2COM: facebook makes oculus
2015-03-06T07:08:41 < GargantuaSauce> no, they bought oculus
2015-03-06T07:08:44 < GargantuaSauce> there's a big difference
2015-03-06T07:08:48 < englishman> details details
2015-03-06T07:08:57 < englishman> palmer luckey makes booty shake
2015-03-06T07:09:02 < englishman> facebook makes oculus
2015-03-06T07:09:37 < GargantuaSauce> they use a weird centralized room tracking thing
2015-03-06T07:09:41 < GargantuaSauce> >It's a tracking technology that allows you to track an arbitrary number of points, room scale, at sub-millimeter accuracy 100 times a second
2015-03-06T07:09:47 < GargantuaSauce> this elicits scepticis
2015-03-06T07:09:48 < GargantuaSauce> m
2015-03-06T07:10:11 < englishman> more precision
2015-03-06T07:10:13 < GargantuaSauce> please tell me you know the answer to that
2015-03-06T07:10:37 < GargantuaSauce> you cant integrate an accelerometer to get position like tha
2015-03-06T07:10:43 < GargantuaSauce> thats just madness
2015-03-06T07:11:05 < GargantuaSauce> you need position in addition to orientation
2015-03-06T07:11:14 < GargantuaSauce> in order for it to not suck
2015-03-06T07:11:33 < GargantuaSauce> because your nose is not the centre of the universe?
2015-03-06T07:11:45 < Getty> some people believe that, tho
2015-03-06T07:11:53 < GargantuaSauce> you thought wrong
2015-03-06T07:12:15 < Getty> its like "you are 20 degree differnt from before"
2015-03-06T07:13:07 < englishman> what is your reference
2015-03-06T07:13:10 < englishman> inside of the cabin?
2015-03-06T07:13:24 < ReadError> it detects distance
2015-03-06T07:13:29 < ReadError> so if you lean in towards something
2015-03-06T07:13:32 < ReadError> it does the same
2015-03-06T07:14:26 < ReadError> yea, and it has it
2015-03-06T07:14:41 < ReadError> uses a webcam shit and IR
2015-03-06T07:15:07 < ReadError> yes
2015-03-06T07:15:13 < GargantuaSauce> the dk2's position tracking is basically the same as that
2015-03-06T07:16:49 < GargantuaSauce> in a fighter jet there are buttons behind the stick
2015-03-06T07:16:55 < GargantuaSauce> in your scheme they would be permanently occluded
2015-03-06T07:17:15 < Getty> reminds me of what i only did ever with my ardupilot
2015-03-06T07:17:43 < Getty> connect it to my computer, started the software, hold it in hand, and giggled like a girl when the tilting was shown on the screen
2015-03-06T07:17:52 < GargantuaSauce> heh
2015-03-06T07:17:57 < Getty> like a child holding a plane-model ;-) i even made the sounds
2015-03-06T07:18:24 < Getty> Eletronics - we make 30 years old 5 again ;-)
2015-03-06T07:18:38 < GargantuaSauce> and then you threw it away and replaced it with a flight controller that doesn't suck?
2015-03-06T07:18:53 < Getty> well as we never did any flight i cant say it suxx
2015-03-06T07:19:13 < Getty> and for our purposes (very slow flight over small area) i thing even a shitty one is fine
2015-03-06T07:24:44 < GargantuaSauce> that is...a different type of flight controller
2015-03-06T07:24:50 < Getty> holy shit
2015-03-06T07:25:21 < Getty> thats the kind of stuff i would love to produce
2015-03-06T07:25:34 < GargantuaSauce> very niche market though
2015-03-06T07:25:45 < Getty> we have no problem innovating
2015-03-06T07:25:49 < Getty> we have only a cashflow problem
2015-03-06T07:25:58 < Getty> throw money at us, and we make whatever you want
2015-03-06T07:27:51 < Getty> what we do right now is also niche :(
2015-03-06T07:28:00 < Getty> but we got a customer who pays us for making those devices
2015-03-06T07:28:12 < Getty> the LED control stuff, dayplanner and weather simulation
2015-03-06T07:28:30 < Getty> http://www.ledaquaristik.de/SunRiser-8-Tagessimulation-und-Lichtsteuerung thats the device http://srdemo.ledaquaristik.de/ thats a demo of the webinterface on it
2015-03-06T07:28:34 < Getty> yes ;)
2015-03-06T07:28:36 < Getty> cant deny that
2015-03-06T07:29:26 < Getty> but we do actually "Kill" the complete market with this. Its by far outstanding next to the opponent devices
2015-03-06T07:29:34 < Getty> (by price AND by features)
2015-03-06T07:30:52 < qyx_> for fishies
2015-03-06T07:32:51 < Getty> fishy people are really keen on all this
2015-03-06T07:33:16 < qyx_> nah, 313 lines of documentation for 262 lines of code
2015-03-06T07:33:38 < Getty> pay me ;)
2015-03-06T07:34:22 < qyx_> haha
2015-03-06T07:34:31 < qyx_> startup-style vs. endterprise-style
2015-03-06T07:34:36 < qyx_> -d
2015-03-06T07:36:07 < Getty> R2COM: thats not how electronic development works ;)
2015-03-06T07:37:07 < Getty> the last request was so complex, it ended up with that we requested 5000 EUR only for being able to define what the prototype might will cost (with unknown production costs) ;-)
2015-03-06T07:37:17 < Getty> but as usual with americans, they stepped back
2015-03-06T07:37:31 < Getty> R2COM: thats how a company with money works
2015-03-06T07:37:40 < Getty> R2COM: thats not how individual competences can work
2015-03-06T07:37:41 < GargantuaSauce> money and multiple teams
2015-03-06T07:37:47 < GargantuaSauce> and infrastructure
2015-03-06T07:38:09 < Getty> for 5000 EUR we wouldnt be able to get a prototype for that ;)
2015-03-06T07:38:31 < Getty> key management of car dealer
2015-03-06T07:38:44 < Getty> existing solutions are all crap
2015-03-06T07:39:09 < Getty> mh? we would have charged 5000 EUR for a complete analyze of the technological possibilties to find out ways that are a probably chance of leading to a good device
2015-03-06T07:39:36 < Getty> you do realize that "device" is 95% mechanics and 5% electronics, or?
2015-03-06T07:39:40 < Getty> no
2015-03-06T07:39:44 < Getty> 5000 EUR for a lot of work?!?!?!?
2015-03-06T07:40:12 < Getty> the electronics we can plan "blind", but noone can blindly plan mechanics without knowing the used technologies in detail
2015-03-06T07:40:26 < Getty> yes, its a huge topic
2015-03-06T07:40:42 < Getty> we would require to make at least 3 or 4 plans in that timeframe
2015-03-06T07:40:46 < Getty> nt just "one"
2015-03-06T07:40:54 < Getty> as "one" could fail, and the it would be really wasted money
2015-03-06T07:41:13 < Getty> so with 5000 EUR we can guarantee 3-4 possible solutions (with possible costs) which can be picked as "lets try this first"
2015-03-06T07:41:20 < Getty> as in the end: it could be just not working... physics bite
2015-03-06T07:41:50 < Getty> also take in that they wanted to make PRODUCTION, not only "one case"
2015-03-06T07:41:55 -!- Roklobsta [~Roklobsta@ppp118-209-162-240.lns20.mel8.internode.on.net] has quit [Quit: KVIrc 4.2.0 Equilibrium http://www.kvirc.net/]
2015-03-06T07:42:09 < Getty> and 5000 EUR for a first pricetag direction for a production looks pretty cheap
2015-03-06T07:43:01 < Getty> i would ;)
2015-03-06T07:43:04 < Getty> but its hard to get customers
2015-03-06T07:43:08 < qyx_> doesn't look too much for me neither if that includes analysis of multiple solutions
2015-03-06T07:43:17 < qyx_> and i am not even german
2015-03-06T07:43:34 < Getty> qyx_: yeah it was a fair deal, and also taken in that it "grows bigger"
2015-03-06T07:43:49 < Getty> qyx_: so the value of the work would have been probably more like 8000-10000 EUR
2015-03-06T07:44:44 < qyx_> thats not even enough money to pay 4 people for one week
2015-03-06T07:45:39 < qyx_> ok, bedtime, 6:45am
2015-03-06T07:56:04 < Getty> we dont need 4 ;)
2015-03-06T07:56:06 < Getty> we just need my dad
2015-03-06T07:56:13 < Getty> 50 years of device making now
2015-03-06T07:56:17 < Getty> he saw all shit
2015-03-06T07:57:13 < Getty> ?
2015-03-06T07:57:25 < Getty> my dad has no contact to americans, i do the talking
2015-03-06T07:57:52 < jpa-> kakeman: my code enables the TPIU and also DWT trace data, i think the ST's "single wire viewer" tool can only show basic ITM software writes and maybe only without TPIU formatting
2015-03-06T08:06:19 < Getty> R2COM: Anything? ;) if its not nano (missing equipment eh ;) )
2015-03-06T08:11:56 < Getty> now i have to discuss with forum admins about "advertisment"
2015-03-06T08:12:05 < Getty> what i did? I replied to a thread about OUR product........
2015-03-06T08:12:20 < emeb_mac> you bad bad man
2015-03-06T08:12:28 < Getty> yeah, i feel so horrible now
2015-03-06T08:12:39 < emeb_mac> capitalist pig
2015-03-06T08:17:48 < Getty> ok now they went more detailed
2015-03-06T08:18:17 < Getty> its about me linking too often (i dont even ALWAYS make a link if i mention the company name, only when its about the actual product sale) in the thread
2015-03-06T08:18:40 < Getty> you know, in the thread about the product which is only buyable at this one company........ and i link to that company too often.... in that thread.... of this product... of this company
2015-03-06T08:19:02 < Getty> using forums in germany is stressful... really... they ALL are so picky bastards
2015-03-06T08:20:24 < emeb_mac> .de has a reputation for being persnickety
2015-03-06T08:24:38 < Getty> emeb_mac: yeah... the sad part is the people dont "use" that proper
2015-03-06T08:24:55 < Getty> emeb_mac: i worked 2-3 years in an american company, the most horrible experience of my life
2015-03-06T08:25:13 < emeb_mac> heh
2015-03-06T08:25:33 < Getty> americans have no sense of the word "productivity" "logic" or "security"
2015-03-06T08:25:44 < Getty> they just 100% miss those concepts
2015-03-06T08:25:50 < Getty> always
2015-03-06T08:25:51 < Getty> all day
2015-03-06T08:26:50 < Getty> also.... some of the american standard rules are a bit weir
2015-03-06T08:26:51 < Getty> d
2015-03-06T08:26:56 < Getty> like..... no internal critic.....
2015-03-06T08:27:18 < Getty> that concept doesnt exist, at all. You are not allowed to critic other co-workers, you are not even allowed to complain to the higher level.
2015-03-06T08:27:47 < dongs> buying 5k of PIC12F615,,, $.38/ea heh
2015-03-06T08:27:47 < Getty> not in the way that germans do _ALL DAY_.... its like not possible to work with a german without getting constantly reminded what you could do better (till you do it better)
2015-03-06T08:27:51 < emeb_mac> really depends on the company
2015-03-06T08:27:53 < dongs> IN DIP
2015-03-06T08:28:08 < Getty> emeb_mac: its the base cutlure, of course there are ALWAYS everywhere companies with brain
2015-03-06T08:28:17 < Getty> emeb_mac: but that is expected as default
2015-03-06T08:28:43 < Getty> emeb_mac: noone would critic in US without someone allowing him todo so, while you cant stop a german at all from doing so ;)
2015-03-06T08:28:55 < GargantuaSauce> how about telling people that they're making retarded generalizations
2015-03-06T08:28:57 < GargantuaSauce> is that allowed
2015-03-06T08:29:01 < Getty> i cant remember one time where we had a new guy in the company and he didnt pointed out something we did bad
2015-03-06T08:29:30 < Getty> GargantuaSauce: well if you cant say what is majority the we cant fix it ;)
2015-03-06T08:29:43 < Getty> GargantuaSauce: dont remind me of the white wash mentality of americans ;)
2015-03-06T08:30:43 < GargantuaSauce> you're full of shit
2015-03-06T08:30:47 < Getty> hehehe
2015-03-06T08:33:59 < Getty> in US i had a date with a startup lady, she made mobile apps for bio companies, 20 employee, pretty successful, and........... she was creationist
2015-03-06T08:34:14 < Getty> i will never ever get this out of my brain
2015-03-06T08:34:19 < Getty> in what way?
2015-03-06T08:34:31 < Getty> i ended the date gracefully as soon as possible ;-)
2015-03-06T08:35:11 < Getty> not really.... at some point i cant get over mentality problems ;) she needs therapy but better let her make _BIO_ apps......
2015-03-06T08:36:39 < Getty> but since that i know, creationist in germany (who talk about it public) go into mental hospital, and in US you give them investment money and let them make bio apps ;-)
2015-03-06T08:37:14 < Getty> oh yeah, very hot asian

2015-03-06T13:40:20 < GargantuaSauce> i cant immediately see why that wouldnt work and that bothers me
2015-03-06T13:41:14 < GargantuaSauce> i mean other than the seals being bullshit there's gotta be something fundamentally wrong with it
2015-03-06T13:41:28 < qyx_> i think that the hydrostatic pressure may prevent the balls from entering the water
2015-03-06T13:41:44 < dongs> my balls will enter any water
2015-03-06T13:42:13 < Laurenceb> then the air bubbles enter
2015-03-06T13:42:26 < Laurenceb> you need to overcome pressure

2015-03-06T13:45:20 < dongs> um is tehre any way to make a huge board in altium

2015-03-06T13:45:32 < dongs> i cant see a way to resize  the canvas/wahtever
2015-03-06T13:46:26 < jpa-> does it have some actual limit or are there just some default borders on the screen?
2015-03-06T13:46:41 < jpa-> atleast in kicad you can just remove the borders, they are just drawings

2015-03-07T00:30:04 < zyp> kakeman, it's fast because they just dump to a ram buffer
2015-03-07T00:30:19 < zyp> i.e. it's nonblocking
2015-03-07T00:31:34 < kakeman> yes
2015-03-07T00:32:09 < zyp> you can do the same yourself by just duming to a ram buffer, then reading it out through the debugger while your code runs
2015-03-07T00:32:17 < kakeman> but doesn't itm take less processor time that that?

2015-03-07T00:36:16 < zyp> printing via itm requires as much processor time as printing into a buffer
2015-03-07T00:36:47 < zyp> when all you do is using itm for putch()

2015-03-07T00:55:42 < kakeman> those happen non-blocking too?
2015-03-07T00:58:38 < kakeman> found that this jlink gdb software outputs swo data to telnet 2333
2015-03-07T00:58:48 < kakeman> so trying to record it
2015-03-07T00:59:21 < zyp> of course not
2015-03-07T00:59:45 < zyp> you can't do nonblocking io without a buffer unless you have a channel that can keep up with the cpu, and you don't
2015-03-07T01:00:19 < kakeman> so ram buffer dump is faster in practical case
2015-03-07T01:00:31 < kakeman> nice
2015-03-07T01:00:56 < zyp> what's even faster is dropping the printing/formatting completely, and letting the host side handle that
2015-03-07T01:01:51 < kakeman> yes
2015-03-07T01:02:30 < kakeman> but don't you need real time stuff running on host side to format and show stuff realtime?
2015-03-07T01:02:35 < zyp> when I wrote my usb stack, I needed a way to log stuff fast, so I wrote logging code that just dumps string pointers and arguments into a buffer, and then I wrote a gdb plugin that digs the data out of the buffer and formats it
2015-03-07T01:02:54 < kakeman> oh gbd plugins yes
2015-03-07T01:03:08 < kakeman> *gdb

2015-03-07T02:30:18 < dongs> 7. There have been a few parts were part of Zano that we have just been notified are scheduled to no longer be produced. This is common in the electronics industry and this wouldn't affect us for 12 months but we are doing a few updates to design those parts out so that when we produce Zano in volume, they will all be the same hardware for the next two years.
2015-03-07T02:30:23 < dongs> ?????????????????????????????????????????????????????????????????????????????????????????????????????????
2015-03-07T02:30:44 < kakeman> LPC_CT16B0 etc.
2015-03-07T02:30:54 < dongs> 3. Onto Zano hardware, every single piece is now tested. A few minor issues but nothing major. Just little things like some digital noise appearing on some analogue lines. Only milli-volts but noise I don't want there so a few minor filtering updates and power supply changes to remove these.
2015-03-07T02:31:38 < kakeman> how hard zano trolls you dongs?
2015-03-07T02:33:30 < Steffanx> someone didn't read NRND?

2015-03-07T05:06:15 < kakeman> do you know if there is high voltage buck regulators for ~300volts
2015-03-07T05:06:25 < kakeman> @_@
2015-03-07T05:07:02 < kakeman> input around 300, output around 15
2015-03-07T05:08:33 < kakeman> is that how hard to archive that kind of ratio?
2015-03-07T05:08:58 < kakeman> big inductor and cap certainly
2015-03-07T05:11:34 < qyx_> use anything meant for ac
2015-03-07T05:11:38 < qyx_> it is rectified anyway
2015-03-07T05:11:47 < qyx_> simple switchers like ST viper would work
2015-03-07T05:11:59 < kakeman> just looking such
2015-03-07T05:12:25 < qyx_> viper06 or viper17 or whatever
2015-03-07T05:12:34 < qyx_> there are many
2015-03-07T05:12:46 < qyx_> other manufacturers also
2015-03-07T05:13:27 < qyx_> also st has some appnotes describing how to use flyback switcher in a buck configuration

2015-03-07T05:34:56 < Viper168> I hear the viper168 is the superior version
2015-03-07T05:34:57 < green1> mine too
2015-03-07T05:37:26 < kakeman> some 20M pictures maybe

2015-03-07T05:39:46 < kakeman> viper53 looks to be the killer when it comes to efficiency
2015-03-07T05:40:20 < kakeman> rds(on) 1ohm
2015-03-07T05:40:48 < qyx_> wat
2015-03-07T05:40:54 < qyx_> what wattage are you targetting?
2015-03-07T05:41:06 < qyx_> when the efficiency is a concenr
2015-03-07T05:41:26 < kakeman> no but what efficiency im targeting
2015-03-07T05:41:31 < kakeman> is highest possible
2015-03-07T05:41:50 < qyx_> in a 300->15V buck?
2015-03-07T05:41:56 < qyx_> use flyback then
2015-03-07T05:42:11 < kakeman> you suppose it's main electricity?
2015-03-07T05:42:15 < kakeman> it's not
2015-03-07T05:42:20 < qyx_> it doesnt matter
2015-03-07T05:42:25 < kakeman> ok
2015-03-07T05:42:31 < qyx_> its too much stepdown to be efficient
2015-03-07T05:42:34 < qyx_> in a buck topology
2015-03-07T05:42:49 < kakeman> yes
2015-03-07T05:43:20 < kakeman> what is reason to use those?
2015-03-07T05:43:27 < kakeman> high voltage bucks
2015-03-07T05:43:31 < qyx_> that is suitable eg. for powering a small mcu directly from mains
2015-03-07T05:43:43 < qyx_> if no isolation is required
2015-03-07T05:43:44 < kakeman> little power yes
2015-03-07T05:44:33 < qyx_> just grab a reference flyback schematic
2015-03-07T05:44:45 < qyx_> there are those standard flyback transformers available for cheap from china
2015-03-07T05:45:04 < qyx_> anc crop the sch after the rectifier
2015-03-07T05:45:11 < qyx_> and recompute things from 315V to 300V
2015-03-07T05:45:32 < qyx_> or don't bother
2015-03-07T05:45:39 < kakeman> I wouldn't

2015-03-07T07:05:38 < dongs> like all of them
2015-03-07T07:05:46 < ds2> you loose the ability to set them

2015-03-07T14:41:12 < dongs> but i think that one costs like 20k

2015-03-07T14:46:05 < green1> which pcb designer u use ?
2015-03-07T14:46:13 < green1> i am learning eagle pcb.
2015-03-07T14:47:03 < dongs> do yourself a favor and don't.
2015-03-07T14:47:18 < dongs> and try diptrace instead.
2015-03-07T14:48:25 < karlp> eagle sucks, but it works and yo ucan get help.

2015-03-07T14:48:58 < dongs> and it comes with a tutorial pdf, after reading which you'll be a schematic/pcb expert
2015-03-07T14:49:02 < dongs> ... so does eagle???

2015-03-07T14:49:10 < karlp> like anyone pays for eagle.
2015-03-07T14:49:11 < dongs> karlp: also, they DO have free and/or cheap student edition
2015-03-07T14:49:20 < dongs> which is less retardedly limited than eagle
2015-03-07T14:49:25 < dongs> i.e. some large number of pins
2015-03-07T14:49:31 < dongs> vs a 5x5cm work area in freetard eagle
2015-03-07T14:49:38 < ReadError> 2 layer and 200 pins
2015-03-07T14:49:40 < ReadError> i think
2015-03-07T14:49:41 < karlp> reason to use eagle is you can follow adafruit/arduino friends guides and gethelp on forums :)

2015-03-07T14:50:22 < dongs> see, this is why people should NOT be using eagle
2015-03-07T14:50:27 < ReadError> maybe you should try #arduino
2015-03-07T14:50:31 < karlp> $75 to get 300 pins
2015-03-07T14:50:35 < dongs> green1: you need to learn how to make your own footprints
2015-03-07T14:50:36 < karlp> that's pretty shit

2015-03-07T14:51:34 < dongs> i think thats pretty decent.
2015-03-07T14:51:38 < karlp> probably is.
2015-03-07T14:51:44 < dongs> anyway, i paid for full and haven't regretted it
2015-03-07T14:51:48 < karlp> but beginners always want footprints anyway
2015-03-07T14:51:55 < dongs> it lasted me a few good years
2015-03-07T14:52:02  * karlp shrugs, I'm just trolling, haven't actually made a pcb in ..... 9 months?
2015-03-07T14:52:14 < dongs> karlp: making footprints in dicktrace is so piss easy you would spend more time looking for them than making your own library
2015-03-07T14:52:15 < specing> I havent made a pcb in 3years
2015-03-07T14:52:18 < karlp> I've harassed the guy at work doing it though to do less fuck ups.
2015-03-07T14:52:20 < specing> beat me
2015-03-07T14:52:37 < karlp> specing: yeah, that pcb is stil on the desk, doesn't work well, and never finished the software

2015-03-07T14:53:48 < dongs> you wouldnt want to anyway
2015-03-07T14:53:53 < dongs> most eagle patterns are horribly
2015-03-07T14:54:20 < karlp> dongs, I think I mean that as a beginner, you want footprints, and you _need_ to be burned by bad footprints before you accept that you need to do this all yoruself anyway
2015-03-07T14:54:27 < karlp> and then you're free to move on to anything in the world
2015-03-07T14:54:31 < GargantuaSauce> it kind of blows my mind that there isn't a standard format that manufacturers release patterns in
2015-03-07T14:54:36 < karlp> eagle is just th eplace you learn that valuable lesson
2015-03-07T14:54:52 < karlp> GargantuaSauce: sure there is, whatever the format mentor/cadene use right?
2015-03-07T14:54:54 < dongs> GargantuaSauce: haha, have you used the shit Analog releases their stuff in?

2015-03-07T15:09:21 < dongs> my kids usually do not have the sense where the camera is focusing on (as they are still young). And I can only see their forehead, or eyebrows at most. With the follow me feature, 1. the phone needs not be held for them; 2. they can run around and Zano will follow them. 3. the face recognition can show their faces correct, PLUS 4. they won't rob the phone away. - Think very optimistically
2015-03-07T15:10:09 < kakeman> they can rob the zano
2015-03-07T15:10:16 < kakeman> and beat it into pieces

2015-03-07T16:15:08 < qyx_> lol
2015-03-07T16:17:07 < kakeman> I'm not too woried about undersized fuses
2015-03-07T16:17:59 < kakeman> It says 1000v on front
2015-03-07T16:18:11 < kakeman> there is no way I plug this to 1000v ever
2015-03-07T16:19:00 < kakeman> I wouldn't touch those probes at 1000v
2015-03-07T16:19:54 < qyx_> i have ut61 and the fused inputs are not rated for 1000V
2015-03-07T16:19:56 < qyx_> 250V only
2015-03-07T16:20:33 < qyx_> only one input is 1000V
2015-03-07T16:20:51 < kakeman> voltage input?
2015-03-07T16:21:11 < kakeman> the thing is that fuse won't arc over
2015-03-07T16:21:44 < kakeman> how it possibly could?
2015-03-07T16:21:49 < qyx_> yes, voltage input
2015-03-07T16:22:09 < kakeman> but if there is 1000V at current input
2015-03-07T16:22:12 < kakeman> it may
2015-03-07T16:22:16 < kakeman> arc over
2015-03-07T16:23:12 < qyx_> how are you going to get 1000V between two probes when mesuring current?
2015-03-07T16:23:19 < qyx_> ok, when the fuse fails
2015-03-07T16:23:38 < kakeman> yes
2015-03-07T16:24:04 < qyx_> and besides that i said that ut61 current inputs are 250V only
2015-03-07T16:24:17 < kakeman> yes
2015-03-07T16:24:23 < qyx_> so no 1000V here
2015-03-07T16:26:43 < kakeman> but if there was
2015-03-07T16:30:25 < kakeman> I were thinkin about dave crying about fuses
2015-03-07T16:30:43 < kakeman> so that you don't have all rated voltages there
2015-03-07T16:31:14 < kakeman> but if there is no current
2015-03-07T16:31:37 < kakeman> in voltage measurement part

2015-03-07T19:25:17 < kakeman> and all stimulus channels are silent but 2
2015-03-07T19:25:27 < kakeman> that has hello!

2015-03-07T19:28:08 < kakeman> but I think I tried this yesterdat but this viewer is shiette and stores old noise until you "playback" it
2015-03-07T19:28:37 < kakeman> so it seemed like there was no effect
2015-03-07T19:31:43 < kakeman> maybe this program can't handle etm sync packages or something there?

2015-03-07T20:01:38 < kakeman> http://emide.org/documentation_debugging_trace.html I meant this
2015-03-07T20:02:28 < Steffanx> looks like emblocks but different
2015-03-07T20:02:42 < kakeman> meh it is not swo thing
2015-03-07T20:03:25 < GargantuaSauce> wonder if it's tolerable

2015-03-07T20:04:55 < GargantuaSauce> >A Linux and Mac version is planned for some time in the future. Since the code is based on Code::Blocks and wxWidgets, it is mostly easily portable to Mac and Linux Systems.

2015-03-07T20:06:25 < kakeman> no etm via swo -> no gain
2015-03-07T20:07:17 < GargantuaSauce> more like codeblocks-based -> no gain
2015-03-07T20:07:32 < kakeman> yes
2015-03-07T20:09:20 < jpa-> kakeman: yeah, probably your swv viewer does not support TPIU formatting
2015-03-07T20:10:15 < jpa-> GargantuaSauce: yeah; under linux i usually start pulseview from terminal so it finds the file from current working directory, but made the video so that it'll work for windows dudes
2015-03-07T20:11:27 < jpa-> kakeman: etm via etb can be useful also, but for different purposes; more like backtrace-on-steroids
2015-03-07T20:11:34 < GargantuaSauce> anyway it looks pretty fantastic, i am gonna have to dust off the OLS and give it a shot
2015-03-07T20:11:48 < Steffanx> ols is still alive?
2015-03-07T20:11:56 < GargantuaSauce> well the one on my desk is
2015-03-07T20:12:15 < GargantuaSauce> i havent jumped on the salae clone bandwagon yet
2015-03-07T20:13:03 < GargantuaSauce> or is there some other cheap LA all the cool kids are using these days that I'm unaware of?
2015-03-07T20:13:22 < jpa-> beaglelogic is one possibility

2015-03-07T20:14:21 < Tectu> hi there
2015-03-07T20:14:22 < GargantuaSauce> no sigrok support just yet? also LA implemented on a soc running linux? r u srs
2015-03-07T20:14:25  * Tectu takes it to the knee
2015-03-07T20:16:05 < kakeman> jpa-: nope. I wants swo
2015-03-07T20:16:47 < jpa-> kakeman: swo can be with or without tpiu formatting
2015-03-07T20:17:27 < jpa-> GargantuaSauce: well beaglelogic gives binary file, you can just do   sigrok-cli -i foobar -I binary:samplerate=100000000 -o foobar.sr   to convert it
2015-03-07T20:17:39 < jpa-> though Abhishek_ has been working on sigrok support also, not sure if it is done yet
2015-03-07T20:17:50 < GargantuaSauce> i wonder what the jitter is like
2015-03-07T20:18:00 < GargantuaSauce> i cant help but think it would be very significant
2015-03-07T20:18:07 < jpa-> it is implemented on the separate realtime processors on the SoC
2015-03-07T20:18:46 < GargantuaSauce> ahhhh i forgot about that
2015-03-07T20:19:16 < jpa-> "Since the BeagleLogic bindings for libsigrok have been merged upstream, the latest built-from-source sigrok libraries and tools support capturing from BeagleLogic."

2015-03-08T00:42:29 < GargantuaSauce> upgrdman: wouldnt be that bright to the eye without being at least a few watts
2015-03-08T00:42:32 < GargantuaSauce> probably a long exposure
2015-03-08T00:44:16 < gxti> changing exposure doesn't affect relative brightness compared to the room; looks like normal overhead room lights to me. probably just a hint of fog.
2015-03-08T00:44:38 < GargantuaSauce> i dont think they'd expose a working optical setup to particulates like that
2015-03-08T00:44:48 < gxti> or just a lot of watts
2015-03-08T00:45:07 < GargantuaSauce> my googles tell me spectroscopy is done at a few mW
2015-03-08T00:45:54 < gxti> or photoshop
2015-03-08T00:46:15 < GargantuaSauce> yeah maybe a long exposure in the dark composited with a short one with lighting

2015-03-08T14:14:57 < Tectu> small spikes are 140MHz clock from some silly DAC
2015-03-08T14:15:00 < Tectu> that is driven by LDO
2015-03-08T14:15:08 < Tectu> supplied*
2015-03-08T14:16:33 < qyx_> is it properly decoupled? it might be unhappy with that
2015-03-08T14:17:47 < Tectu> qyx_, well, I listened to the DACs datasheet and use a 10nF and a 100nF cap directly on each of the three DAC power input pins. The LM1117 LDO that I sadly use has 10uF on input and 10uF on output
2015-03-08T14:17:54 < Tectu> the LDO does only supply that DAC - nothing else
2015-03-08T14:18:27 < qyx_> O_o i assumed this is some sort of switcher
2015-03-08T14:18:31 < GargantuaSauce> low esr on the decoupling caps can make some ldos unstable
2015-03-08T14:18:35 < qyx_> when there is nearly 500mVpp at 500kHz
2015-03-08T14:18:48 < Tectu> qyx_, it is not. it' is a freakin' LM1117
2015-03-08T14:19:06 < Tectu> GargantuaSauce, interesting. I didn't use low ESR caps, tho. Just the regular X5R crap
2015-03-08T14:19:28 < GargantuaSauce> well ceramics' esr is pretty low
2015-03-08T14:19:33 < qyx_> which voltage and package size?
2015-03-08T14:19:56 < GargantuaSauce> i am not sure what the solution is when the load requires good decoupling
2015-03-08T14:19:58 < GargantuaSauce> series inductor?
2015-03-08T14:20:43 < Tectu> qyx_, the LM1117 is a SOD-223 or what ever that was. This huge package. The DAC is a TQFP-48
2015-03-08T14:21:02 < qyx_> no, the caps at lm1117
2015-03-08T14:21:15 < qyx_> 0805?
2015-03-08T14:21:59 < qyx_> and voltage rating
2015-03-08T14:22:31 < qyx_> some of 0808 x5r/x7r 10uF at 3.3 may behave more like 1uF
2015-03-08T14:22:49 < qyx_> i tend to use 1206 there instead
2015-03-08T14:23:14 < Tectu> qyx_, 0603 10V
2015-03-08T14:23:18 < qyx_> huh

2015-03-08T14:26:41 < Tectu> qyx_, does it hurt if I just stack two or three 10uF on top of the current ones?
2015-03-08T14:26:47 < Tectu> qyx_, why didn't you tell me before? :P
2015-03-08T14:27:02 < qyx_> try that first, i do the same to verify
2015-03-08T14:27:23 < qyx_> and see if the waveform changes
2015-03-08T14:27:26 < Tectu> I'll let you know about the result
2015-03-08T14:27:29 < qyx_> and if not, it may be wha GargantuaSauce said
2015-03-08T14:27:45 < Tectu> the too low ESR crap?
2015-03-08T14:28:12 < qyx_> i used generic lm1117 only with electrolytic caps
2015-03-08T14:28:21 < Tectu> (crap not as in GargantuaSauce tells crap but that it's a crappy situation here)
2015-03-08T14:28:44 < GargantuaSauce> i will not object to the implication that i'm full of shit
2015-03-08T14:29:27 < GargantuaSauce> another shot in the dark would be that loading the regulator more might help, just with a 500 ohm resistor or something
2015-03-08T14:29:32 < GargantuaSauce> assuming it's not a battery powered application

2015-03-08T14:29:53 < Tectu> it's pretty much everything but battery powered

2015-03-08T14:30:07 < qyx_> the 140MHz DAc is probably loading it properly :>
2015-03-08T14:30:31 < Tectu> :D
2015-03-08T14:30:49 < Tectu> qyx_, it's a 330MHz DAC that I only drive with 140MHz which is already pretty stupid given the setup you can see in the image above ^

2015-03-08T14:31:45 < GargantuaSauce> lol
2015-03-08T14:32:03 < qyx_> nice antenna

2015-03-08T14:32:22 < Tectu> using some 15pF probe
2015-03-08T14:33:07 < Tectu> it's just some silly prototype, I don't mind driving it at 50 MHz. that's why there is the EXT_INPUT SMA there so that I can use an external proper signal to test the amp crap using some generator
2015-03-08T14:33:13 < Tectu> (to bypass the crappy DAC setup)
2015-03-08T14:33:20 < qyx_> nice, i would assume this signal is similarly clearly visible 10 meters far awy
2015-03-08T14:33:47 < Tectu> seriously?
2015-03-08T14:33:53 < Tectu> (I don't know antenna magic)
2015-03-08T14:34:00 < qyx_> idk, check with some sdr
2015-03-08T14:34:05 < Tectu> have none
2015-03-08T14:35:32 < GargantuaSauce> well the example that springs to mind is PATA, whose fastest mode is 40MHz with similar cables/connectors
2015-03-08T14:38:56 < Tectu> yes, I did research that and I remember that the same connectors with 1m cables went up to 33MHz (didn't know about 40MHz)
2015-03-08T14:39:03 < Tectu> so I thought that 100MHz might probably be fine with short cabling xD
2015-03-08T14:39:14 < Tectu> anyway, I can always lower the frequency, no problem in that
2015-03-08T14:39:29 < GargantuaSauce> you certainly might get away with it for a halfassed prototype
2015-03-08T14:40:17 < Tectu> this prototype is not meant to ever leave my room
2015-03-08T14:40:29 < GargantuaSauce> well its signals will ;)
2015-03-08T14:40:56 < qyx_> change to 100MHz and tune with fm receiver
2015-03-08T14:41:08 < qyx_> or don't bother
2015-03-08T14:42:22 < GargantuaSauce> oh i bet that'd sound pretty cool
2015-03-08T14:44:09 < Tectu> rofl
2015-03-08T14:44:39 < qyx_> mhm, which partno is that 330MHz dac?
2015-03-08T14:46:21 < Tectu> so I added some big arse 25V 1000uF electrolyte cap directly to the output side of the LM1117 and the problem didn't exactly become less worse...
2015-03-08T14:48:00 < qyx_> from extreme to extreme
2015-03-08T14:48:49 < GargantuaSauce> come to think of it one of my things with an lm1117 oscillates like mad but only when i power it from my ultrabook usb ports
2015-03-08T14:48:54 < qyx_> also mind the input when using such long cables
2015-03-08T14:50:40 < Tectu> qyx_, so that big arse cap might actually be bad again?
2015-03-08T14:51:18 < GargantuaSauce> yeah you are definitely not supposed to use one that huge
2015-03-08T14:51:20 < GargantuaSauce> for several reasons
2015-03-08T14:51:57 < Tectu> just for general knowledge - can you list them?
2015-03-08T14:52:53 < GargantuaSauce> well there is a region of stability specified in the datasheet, it's a graph of esr vs capacitance and there's a chunk shaded in the middle that you're supposed to stay in for it to not oscillate
2015-03-08T14:53:21 < GargantuaSauce> another reason is a big cap on the output can discharge backwards through the regulator when the input voltage is removed
2015-03-08T14:53:35 < Tectu> oh fuck
2015-03-08T14:53:46 < Tectu> so unsolder it before powering it off? :P   (kidding

2015-03-08T15:05:16 < BrainDamage> the larger a cap the lower the self resonance point
2015-03-08T15:05:27 < BrainDamage> past that it behaves like an inductor instead of a cap
2015-03-08T15:05:51 < BrainDamage> inductor + cap, and you got yourself a nice LC tank

The Root Frequency is defined as 2(10-G) times the frequency of the CLK line. For G=10, the CLK line frequency and Root Frequency are equal.

2015-03-08T16:11:51 < dongs> you done fucked up
2015-03-08T16:17:42 < dongs> Tectu: what is happening exactly
2015-03-08T16:17:44 < dongs> tl;dr version
2015-03-08T16:19:07 < Tectu> dongs, using LM1117 (3.3V fixed version) to supply the power to a high speed DAC that currently runs at 140MHz. Now I see 140MHz all over the place
2015-03-08T16:19:25 < Tectu> dongs, 140MHz in the 3.3V, 5V, 15V... I can even measure it at my lab supplys output.
2015-03-08T16:20:07 < GargantuaSauce> you need some chokes in your life
2015-03-08T16:20:15 < Tectu> dongs, I am using 1x 10nF and 1x 100nF per power input of the DAC as described in the datasheet (took some reference design to copy cat it). LM1117 has 10uF on input and output side  (0603 10uF 10V)
2015-03-08T16:20:24 < Tectu> yes, I bet I do.

2015-03-08T16:55:12 < qyx_> the original was this http://paste.ugfx.org/sores/7505d64a54e0/35e59b19aad7.jpg
2015-03-08T16:55:26 < dongs> ya that
2015-03-08T16:57:45 < kakeman> can EOF in random data in file opened with standard library cause file read to be cut short?
2015-03-08T16:57:56 < dongs> what is "EOF"
2015-03-08T16:57:59 < dongs> you mean the ascii eof symbol?
2015-03-08T16:58:11 < dongs> does anything actually give a shit about that
2015-03-08T16:58:13 < kakeman> something
2015-03-08T16:58:19 < dongs> ctrl+D?
2015-03-08T16:58:35 < dongs> i seriously doubt it, maybe if you opened the file in ascii mode or someshit??
2015-03-08T16:58:43 < dongs> and even then

2015-03-08T17:06:34 < kakeman> something makes my code read only part of file
2015-03-08T17:06:53 < kakeman> let's look with some hex editors
2015-03-08T17:09:35 < qyx_> no, the file contents has nothing to do with the reading
2015-03-08T17:09:54 < qyx_> EOF as an ascii symbol can't break your reading unless you are doing it wrong
2015-03-08T17:10:34 < qyx_> eof as a return value of read or something is not a symbol
2015-03-08T17:10:47 < qyx_> you can also use while (!feof(f)) { ... }
2015-03-08T17:10:58 < qyx_> and post your code
2015-03-08T17:23:23 < Tectu> dongs, serious question: what is that BW Limit in my channel setting doing exactly anyway?
2015-03-08T17:23:34 < GargantuaSauce> just a software lowpass filter
2015-03-08T17:23:35 < Tectu> dongs, does it just limit to the scopes bw? (200Mhz in my case)
2015-03-08T17:23:46 < Tectu> GargantuaSauce, I thought so, but with what cut-off freq?
2015-03-08T17:23:46 < dongs> it'll get rid of that ringing on the edges of square wavez

2015-03-08T17:24:00 < dongs> see, exactly waht you need
2015-03-08T17:24:35 < englishman> Tectu it limits channel bandwidth to a lower value. Usually 20mhz

2015-03-08T17:25:59 < englishman> Unless you're interested in actually investigating higher frequencies, it really just reduces noise
2015-03-08T17:26:11 < Tectu> interesting, thank you verymuch
2015-03-08T17:26:20 < Tectu> dongs, why would you use a tektronix if you can use an agilent
2015-03-08T17:27:23 < kakeman> ok so mode needs to be "rb"
2015-03-08T17:27:29 < kakeman> not "r"
2015-03-08T17:27:37 < dongs> yes, the latter is ascii mode
2015-03-08T17:27:41 < dongs> does that really stop at eof?
2015-03-08T17:27:51 < kakeman> i think A1 stops it
2015-03-08T17:28:12 < kakeman> i had it and one search result had it
2015-03-08T17:28:17 < kakeman> dec 23
2015-03-08T17:29:27 < kakeman> sorry 1A
2015-03-08T17:30:05 < kakeman> dec 26
2015-03-08T17:32:16 < qyx_> yes, 1A is eof
2015-03-08T17:32:26 < qyx_> but wut, what is the language?
2015-03-08T17:32:26 < kakeman> http://en.wikipedia.org/wiki/Substitute_character
2015-03-08T17:32:37 < kakeman> C
2015-03-08T17:32:52 < qyx_> and how are you reading your file?
2015-03-08T17:33:02 < dongs> qyx, fopen("foo", "r")
2015-03-08T17:33:05 < dongs> i.e. in ascii mode
2015-03-08T17:33:08 < dongs> not rb, binary
2015-03-08T17:33:18 < qyx_> it doesn't matter
2015-03-08T17:33:22 < kakeman> obivious is obivious
2015-03-08T17:33:23 < dongs> it does some dickery with the stuff in ascii mode tho
2015-03-08T17:33:24 < qyx_> i meant which function does he used
2015-03-08T17:33:29 < dongs> fread... ?
2015-03-08T17:33:40 < jpa-> is this windows or something?
2015-03-08T17:33:56 < kakeman> error_number_input = fopen_s(&filehandle_input, input_filename_var, "rb");
2015-03-08T17:34:09 < qyx_> what is fopen_s?
2015-03-08T17:34:12 < jpa-> fopen_s, so yeah
2015-03-08T17:34:26 < kakeman> it's compliant with new C
2015-03-08T17:34:39 < kakeman> or something
2015-03-08T17:39:29 < kakeman> it is dones. works now

2015-03-08T17:54:23 < Steffanx> what are we looking at mr Tectu? DAC output?
2015-03-08T17:54:30 < Tectu> yes sir
2015-03-08T17:54:35 < Tectu> also just 50kHz sine
2015-03-08T17:54:36 < Steffanx> looks sinusish
2015-03-08T17:54:46 < Tectu> 140MHz through ribbon cable didn't work out that well
2015-03-08T18:00:52 < dongs> im gonna be sending 1ghz through 2.54mm pin headers soon
2015-03-08T18:01:29 < Steffanx> you're more pro than Tectu so you can do it.

2015-03-08T18:12:20 < jpa-> Tectu: did you forget GND pins or why didn't it work?
2015-03-08T18:12:25 < jpa-> or series resistors
2015-03-08T18:13:59 < Tectu> jpa-, I thought it was smart to arrange my ribbon cable like this:   DAC_D[9:0] then GND, then DAC_CLK
2015-03-08T18:14:12 < Tectu> turns out that crosstalking clock into GND isn't that smart after all
2015-03-08T18:14:20 < jpa-> uh, just one gnd?
2015-03-08T18:15:06 < jpa-> if you want to make life simple, have every 2nd pin as GND, and put 100 ohm series resistor in transmitting end on each data/clock line
2015-03-08T18:15:07 < Tectu> na, got two
2015-03-08T18:15:21 < Tectu> how much will resistors help?
2015-03-08T18:15:25 < jpa-> a lot
2015-03-08T18:15:26 < Tectu> I could retro fit them
2015-03-08T18:16:07 < jpa-> generally a good guess is to have equal number of GND pins as data pins - if you are careful, a bit less is enough also
2015-03-08T18:16:51 < Tectu> jpa-, yep, but the problem is that the pinout of the connector was already set by the dev-board that I am using
2015-03-08T18:16:58 < Tectu> and there are only 2 GND pins on a 40 pin con
2015-03-08T18:17:00 < jpa-> yeah, that happens
2015-03-08T18:17:24 < jpa-> if the gnd pins are in proper positions, you could use the funny 80-pin ata cables though :P
2015-03-08T18:18:05 < Tectu> not sure if they will like 140MHz either :P
2015-03-08T18:18:17 < Tectu> good thing I just bought the 240MHz and not the 10€ more expensive 330MHz DAC
2015-03-08T18:18:24 < jpa-> considering that they're routinely used at 133MHz, i would guess yes
2015-03-08T18:18:31 < Tectu> (and no, guys, I never expected to really use anything > 50MHz on that connector)
2015-03-08T18:19:13 < jpa-> actually 167 MHz was also used over the 80pin flat cables
2015-03-08T18:21:20 < Tectu> shielded I guess?
2015-03-08T18:21:25 < jpa-> nah
2015-03-08T18:21:28 < jpa-> just gnd every other pin
2015-03-08T18:21:33 < GargantuaSauce> its 133MB/s, not 133MHz
2015-03-08T18:21:41 < GargantuaSauce> 2 bytes wide and ddr signallign

2015-03-08T18:22:16 < jpa-> ah.. yeah
2015-03-08T18:24:13 < jpa-> looks like SCSI did 80MHz over flat cable
2015-03-08T18:24:30 < jpa-> depends on cable length also of course
2015-03-08T18:24:37 < GargantuaSauce> i assume that's not single ended
2015-03-08T18:24:50 < jpa-> i guess the easiest way to improve that would be differential signalling
2015-03-08T18:26:23 < GargantuaSauce> a differential parallel bus just feels weird
2015-03-08T18:26:41 < jpa-> why? 
2015-03-08T18:26:57 < GargantuaSauce> well, entirely antiquated at this point
2015-03-08T18:26:58 < GargantuaSauce> must have been loads of fun to match those trace lengths
2015-03-08T18:27:15 < jpa-> isn't lvds still pretty common for TFT screens?
2015-03-08T18:28:24 < Tectu> jpa-,  it is
2015-03-08T18:28:36 < GargantuaSauce> yeah forgot about that
2015-03-08T18:29:05 < jpa-> i wonder if the first limit you hit with unshielded flat cables is the actual data getting corrupted, or just not passing EMC tests
2015-03-08T18:29:28 < GargantuaSauce> probably the latter, though they'd be fairly closely correlated
2015-03-08T18:36:50 < Tectu> why is everybody worrying about EMC these days
2015-03-08T18:37:09 < jpa-> "these days"?
2015-03-08T18:38:12 < Tectu> translates to "since I read IRC crap"
2015-03-08T18:38:20 < GargantuaSauce> since we phased out spark-gap communication?
2015-03-08T18:39:01 < jpa-> Tectu: because it is easier to worry about EMC up front than afterwards
2015-03-08T18:39:31 < Tectu> probably I should worry about that too sometimes

2015-03-08T19:53:12 < Tectu> I plan to contact eurocircuits people first
2015-03-08T19:53:25 < kakeman> I wonder ho I do with 0603s

2015-03-08T19:55:38 < emeb> BrainDamage: Step Attenuator

2015-03-08T19:57:52 < Steffanx> hmm, anyone knows where this german (i cant remember his nick) that was working on his own C++ stm32 lib go?
2015-03-08T19:58:58 < zyp> the guy who were overdoing everything with templates?
2015-03-08T19:59:04 < Steffanx> yes
2015-03-08T19:59:36 < Tectu> emeb, how much does that cost?
2015-03-08T19:59:58 < emeb> Tectu: the step attenuator? Not cheap - like $500 or so IIRC
2015-03-08T20:00:50 < Tectu> emeb, just for my personal information out of pure curiosity... is that attenuator in the same box in your garage as the FPGA stuff?
2015-03-08T20:01:19 < BrainDamage> i have a step attenuator 0-70dB in 10dB increments and it costed me ~100$ used
2015-03-08T20:01:28 < emeb> here's a used one just like mine: http://www.ebay.com/itm/NARDA-STEP-ATTENUATOR-MODEL-AS-SMA-2-5-1-50-No-D-O-A-/190543763093
2015-03-08T20:02:20 < BrainDamage> adding a chinese one for 0-10 in 1dB increments would be extra 30$
2015-03-08T20:02:46 < Tectu> how does that can work?
2015-03-08T20:03:03 < Tectu> DC to 2.5 GHz
2015-03-08T20:03:15 < BrainDamage> it's a bunch of resistors with waveguide geometries
2015-03-08T20:03:41 < BrainDamage> so it's all conduction losses
2015-03-08T20:03:49 < Tectu> sounds just like my 140MHz ribbon cable. Such a rip-off
2015-03-08T20:04:02 < Tectu> just joking... waveguide geometries?
2015-03-08T20:04:25 < BrainDamage> 140MHz ribbon? do you really love near field interference?
2015-03-08T20:04:59 < BrainDamage> you need to stagger signal lines with rail lines to give a place for field lines to close to
2015-03-08T20:05:07 < BrainDamage> and possibly stagger clock windows
2015-03-08T20:05:14 < BrainDamage> but really, why
2015-03-08T20:05:45 < Tectu> BrainDamage, looks like you missed all the fun from today:  http://paste.ugfx.org/sores/7505d64a54e0/6dcf568d6482.jpg
2015-03-08T20:05:58 < englishman> Price depends on frequency
2015-03-08T20:06:16 < englishman> I had a nice rotary attenuator. With 50MHz bandwidth in 7GHz.
2015-03-08T20:06:21 < englishman> It was cheap.
2015-03-08T20:06:36 < BrainDamage> mine is dc to 12 GHz
2015-03-08T20:07:12 < Tectu> BrainDamage, can one really meassure my 140MHz ribbon cable from a distance?
2015-03-08T20:07:18 < Tectu> (sorry, I don't really know stuff about RF
2015-03-08T20:07:52 < Tectu> Abhishek_, btw, the nice thing about inkjet printed silks instead of real silkscreen silks is that you can do serial numbering etc
2015-03-08T20:08:02 < Tectu> (yes, you could obviously add that step after the actual silk
2015-03-08T20:08:16 < Tectu> Abhishek_, also, I think that they still do the real stilk thing but not for single piece prototypes.
2015-03-08T20:08:27 < BrainDamage> Tectu: depending on how you placed the signals on those wires, yes, possibly
2015-03-08T20:08:41 < Abhishek_> hmm
2015-03-08T20:08:52 < Tectu> BrainDamage, first 10 pins are DAC inputs, then comes GND then comes DAC clock
2015-03-08T20:08:55 < BrainDamage> you have a nice spire with perimeter comparable with a fraction of wavelength
2015-03-08T20:09:17 < Tectu> BrainDamage, i couldn't randomly place my grounds between the wires as the pin-out is defined by the dev-board
2015-03-08T20:10:05 < GargantuaSauce> all of those terasic daughter boards have female connectors dont they? ie not designed for using a cable

2015-03-08T20:11:23 < Tectu> GargantuaSauce, well, they don't use the 2.54mm crap anymore anyway. they have now some fancy proprietary HSMC (high speed mezzaine connector) crap that they are using:   http://ca.mouser.com/images/microsites/Terasic_DVI-HSMC_2.jpg
2015-03-08T20:11:33 < Tectu> GargantuaSauce, they only use 2.54mm on the university program boards anmore
2015-03-08T20:11:48 < GargantuaSauce> ah
2015-03-08T20:11:56 < GargantuaSauce> i still have my de-2 kicking around unused
2015-03-08T20:12:04 < Tectu> why? such a great board
2015-03-08T20:12:17 < GargantuaSauce> just havent bothered wrestling with quartus
2015-03-08T20:12:23 < Tectu> quartus is awesome
2015-03-08T20:12:24 < Tectu> really
2015-03-08T20:12:27 < Tectu> never had any issue with it
2015-03-08T20:12:34 < GargantuaSauce> i am sure its fine in windows
2015-03-08T20:12:41 < Tectu> GargantuaSauce, I used it on linux too
2015-03-08T20:12:48 < Tectu> GargantuaSauce, that was 2 years ago, quartus 13.1 worked like a charm
2015-03-08T20:12:54 < Tectu> now I use 14.0 but on windows
2015-03-08T20:13:03 < GargantuaSauce> it's very ubuntu-centric
2015-03-08T20:13:08 < Tectu> GargantuaSauce, I used in on Arch
2015-03-08T20:13:23 < GargantuaSauce> well i cant remember exactly what my trouble was
2015-03-08T20:13:32 < GargantuaSauce> maybe i am thinking of the xilinx ise
2015-03-08T20:14:15 < Tectu> I bet
2015-03-08T20:14:15 < BrainDamage> used quartus 12 on arch quite ok too

2015-03-09T03:43:19 < dongs> hmm, shitty contact on dp lines maybe, but usually it doesnt look like that
2015-03-09T03:43:30 < dongs> is white = glowing white in the center with fuzzy corners?
2015-03-09T03:43:36 < dongs> or you can see some crap through it that should be on screen?
2015-03-09T03:45:45 < englishman> Is your connector latch broken? The FPC one

2015-03-09T04:22:42 < dongs> englishman: o rite
2015-03-09T04:32:59 < zyp> dongs, I can see a BW, partly garbled image of what should be displayed
2015-03-09T04:33:38 < zyp> this is the panel that worked perfect with the old board, but not the new board I got from you when I bought that acrylic case last year
2015-03-09T04:33:54 < zyp> haven't yet bothered taking apart the acrylic case to test it with the old board again
2015-03-09T04:38:21 < dongs> huh, that shouldnt matter
2015-03-09T04:38:29 < dongs> DP part is just 1:1 connection anyway
2015-03-09T04:38:38 < dongs> so unless its making shit contact, it should work
2015-03-09T04:38:50 < zyp> yeah, idk
2015-03-09T04:39:33 < zyp> I didn't test new board before I put together the acrylic, panel worked with old board before that
2015-03-09T04:40:00 < dongs> if that helps any, i have the new one inside acrylic case working just find behind me on a macmini :)
2015-03-09T04:40:09 < dongs> er, just fine
2015-03-09T04:40:17 < zyp> I was cleaning up some mess here the other day, and found the acrylic case under a pile of mess, so I decided to test it again today, and it still didn't work :p
2015-03-09T04:40:35 < dongs> it works nice with a macmini, just sitting on top of it
2015-03-09T04:41:21 < zyp> well, I don't doubt the acrylic case works, and that the board is supposed to work
2015-03-09T04:41:28 < zyp> I just wonder what is wrong with mine
2015-03-09T04:41:34 < dongs> got pics?
2015-03-09T04:41:39 < dongs> maybe connector not fully inserted or something?
2015-03-09T04:41:47 < dongs> and making shitty contact
2015-03-09T04:41:52 < dongs> that would be like the only reason i can think of
2015-03-09T04:42:11 < zyp> are you testing the boards to rule out solder bridges and shit?
2015-03-09T04:42:12 < dongs> the only p[eople i had complain about the stuff not working were those who plugged it in backwards once
2015-03-09T04:42:15 < dongs> and applied power
2015-03-09T04:42:18 < zyp> heh
2015-03-09T04:42:26 < dongs> then the screen becomesd white glow in the center
2015-03-09T04:42:31 < dongs> (*once plugged in correctly)
2015-03-09T04:42:45 < zyp> how do you manage that, isn't it a single sided connector? :p
2015-03-09T04:42:48 < dongs> zyp, I do now, i'm not sure if the one you got was - but this hasnbt been a problem for a while since i got the process down
2015-03-09T04:42:56 < dongs> you can still fit it in
2015-03-09T04:43:01 < dongs> but hte molex has contacts on both ends
2015-03-09T04:43:12 < dongs> so if you do plug it in backwards it still makes contact
2015-03-09T04:43:41 < dongs> you can look at DP plug , the shorts would be obvious if they were there
2015-03-09T04:43:49 < dongs> but i dunno if this black and white shit sounds like a short
2015-03-09T04:43:56 < dongs> usually it just doesnt work at all when a lane is shorted
2015-03-09T04:44:00 < dongs> not scrambled crap
2015-03-09T04:44:26 < zyp> yeah, most of the time it's like that
2015-03-09T04:44:41 < zyp> if I unplug/replug it a couple of times, I get scrambled crap
2015-03-09T04:44:45 < dongs> Are you using teh lunix
2015-03-09T04:44:48 < zyp> so I guess it's some detection timing
2015-03-09T04:44:49 < zyp> no
2015-03-09T04:45:37 < zyp> and I have other DP monitors that work, so I'm certain the cable/signal is otherwise good

2015-03-09T05:11:09 < dongs> ipad screen runs at 4lane/1.62gbps mode
2015-03-09T05:11:12 < dongs> not in 2.7gbps mode
2015-03-09T05:14:27 < qyx_> unpinned pin
2015-03-09T05:14:35 < qyx_> is that made by dong?
2015-03-09T05:15:02 < zyp> hmm
2015-03-09T05:15:08 < zyp> tried soldering it down, still doesn't work
2015-03-09T05:15:11 < dongs> y, there was time at beginning weith those TE connectors that some pins had soldering issues
2015-03-09T05:15:24 < dongs> mostly because they were weirdly bent , staggered
2015-03-09T05:15:35 < dongs> havent seen this lately
2015-03-09T05:15:39 < zyp> oh, and there's an X marked on this board, what does that mean? :p
2015-03-09T05:15:47 < qyx_> lol
2015-03-09T05:16:02 < zyp> tested, failed? :p
2015-03-09T05:16:04 < dongs> zyp, oh, wasnt the deal i send you some shit that failed QC and you figure out how to work it?
2015-03-09T05:16:16 < zyp> was it?
2015-03-09T05:16:22 < dongs> if it has an X on it, yes
2015-03-09T05:16:29 < dongs> so that would explain the unsoldered pin
2015-03-09T05:16:38 < dongs> i wouldnt have sent you a trashed one if you paid for it
2015-03-09T05:17:06 < zyp> didn't I? I don't remember
2015-03-09T05:17:09 < dongs> just run solder + flux across all pins and it hsould be OK
2015-03-09T05:17:53 < dongs> pin6 looks dodgy too
2015-03-09T05:17:58 < dongs> from the jAgQm.JPG
2015-03-09T05:19:16 < zyp> 07:24:38 < dongs> i got a bunch of qcfail ones I can fix up
2015-03-09T05:19:19 < zyp> right
2015-03-09T05:19:27 < zyp> you didn't say I had to fix it though :p
2015-03-09T05:19:50 < zyp> but ok
2015-03-09T05:26:27 < zyp> I think I fixed it
2015-03-09T05:27:04 < zyp> had to press the pins down while removing heat to get them to stay on the pad
2015-03-09T05:30:44 < dongs> yes that helps
2015-03-09T05:34:41 < dongs> like i said there was a reel or something of these TE shits that was particuarly fucked up
2015-03-09T05:34:51 < dongs> all the pins were like _-_-_-_-_-_-_-
2015-03-09T05:35:01 < zyp> ugh
2015-03-09T05:49:14 < zyp> hmm, I want to make a black frame inlay around the panel under the top layer of acryl
2015-03-09T05:49:34 < zyp> since the panel is leaking light around the edges and looking ugly
2015-03-09T05:51:45 < dongs> shit's working now?
2015-03-09T05:55:01 < dongs> nice, premium di.fm works OK in winamp, they give a stream URL wiht some hash at the end and that takes care of premium part

2015-03-09T06:02:57 < emeb_mac> must be
2015-03-09T06:03:03 < emeb_mac> is that just power sequencing?
2015-03-09T06:03:37 < dongs> no, to prevent backflow
2015-03-09T06:03:55 < zyp> wat
2015-03-09T06:04:04 < dongs> because theres ESD diode
2015-03-09T06:04:17 < dongs> so VDD33 can backflow to other shit, if something is plugged into I/O pins
2015-03-09T06:04:31 < dongs> (but its not powered)
2015-03-09T06:09:03 < dongs> howver i dont see evalboard doing this so fuckem

2015-03-09T06:22:41 < dongs> so they're probablyt just trolling
2015-03-09T06:22:49 < englishman> actually
2015-03-09T06:22:54 < englishman> in similar thread
2015-03-09T06:23:09 < englishman> some guitar amps that started being made in china had to use more modern, smaller caps
2015-03-09T06:23:23 < englishman> people noticed that the chink amps were 'inferior'
2015-03-09T06:23:30 < englishman> so they made the caps look older and bigger
2015-03-09T06:23:49 < dongs> suddenly soundstage widened?

2015-03-09T11:01:00 < dongs> PaulFertser: i used ~that feature in keil
2015-03-09T11:01:04 < dongs> its called logic analyzer or somethin there
2015-03-09T11:01:18 < PaulFertser> dongs: yep. Was it useful?
2015-03-09T11:01:18 < dongs> i can barely undersatnd what that atollic dude is speaking his mic blows
2015-03-09T11:01:38 < dongs> PaulFertser: for a fairly narrow definition of useful, i guess so.
2015-03-09T11:01:42 < PaulFertser> dongs: did you just specify some static variable (or memory-mapped register) to be followed and view the graph?
2015-03-09T11:01:46 < dongs> yes
2015-03-09T11:01:50 < dongs> pretty much thats waht it does
2015-03-09T11:02:00 < dongs> but the idea there is that its 'realtime'
2015-03-09T11:02:06 < dongs> instead of grabbing it out of memory orh watever all the time
2015-03-09T11:02:27 < PaulFertser> Yes, it's like a watchpoint but instead of halting it just emits the new value (and/or PC) via trace.
2015-03-09T11:02:35 < PaulFertser> Optionally timestamped.
2015-03-09T11:02:45 < dongs> right

2015-03-09T12:25:27 < dongs> An old man, probably about seventy, decides he'll join us. He sits beside me in the water. I am still sitting on the rim. I am looking out and away from him, at nothing in particular, when I feel his hand fondling my testicles. He has stretched out his arm and has gone underneath both my leg and towel to reach them. I recoil and look at him. He withdraws his hand and raises it either to defend or to excuse himself, and grins apologetically.

2015-03-09T16:28:47 < jpa-> "magic square" means dithering using a constant pattern, right?
2015-03-09T16:31:48 < dongs> For example, when Magic Square algorithm is enabled the red component of the RGB666 output becomes either .R [7:2]. or .R [7:2] + 1.. The ratio of these two values depends on the horizontal and vertical position and the display timing. With this changing pixel value, human eye senses the red color component as .R [7:2]., .R [7:2] + 0.25., .R [7:2] + 0.5. and .R [7:2] + 0.75.. Therefore, the color depth for the human eye becomes almost those of RGB888 data.

2015-03-09T23:11:30 < ehsanv> hi guys, i wanna use a port in both ways(Input/Output) mode. i set GPIOx_ODR bits and then when i make port input(GPIOB->MODER = 0x00000000;) and i read GPIOx_IDR i only read previous ODR i set before :(
2015-03-09T23:12:31 < zyp> that shouldn't be the case
2015-03-09T23:12:58 < zyp> IDR always reads the true pin state, regardless of whether it's configured as input or output
2015-03-09T23:13:13 < zyp> is this on F1 or newer?
2015-03-09T23:13:26 < ehsanv> F407
2015-03-09T23:13:45 < zyp> what do you have hooked up to the pin?
2015-03-09T23:13:59 < ehsanv> the port used for SDRAM DQ0-15 data, i'm interfacing SDRAM on my own, creating a library for it
2015-03-09T23:14:29 < zyp> okay
2015-03-09T23:15:06 < zyp> are you sure the SDRAM output drivers are enabled when you are reading IDR?
2015-03-09T23:16:04 < zyp> because otherwise the pins would be floating, and when floating, capacitance will likely keep them at the same level as the previous output
2015-03-09T23:16:07 < ehsanv> not pretty sure about that, i never worked with SDRAM, have you ever experience with SDRAM?
2015-03-09T23:16:21 < zyp> or in other words, when floating, the pin level is undefined

2015-03-09T23:16:45 < zyp> minor
2015-03-09T23:16:56 < ehsanv> i almost done every step :(
2015-03-09T23:17:12 < zyp> I designed a board with an SDRAM chip once, but I haven't attempted doing the interfacing myself
2015-03-09T23:17:20 < ehsanv> can i attach my piece of code to pastebin for you? would you please help me in this?
2015-03-09T23:17:24 < zyp> sure
2015-03-09T23:17:36 < ehsanv> thanks :)

2015-03-09T23:20:17 < ehsanv> zyp: SDRAM_init(); then SDRAM_test(); called in main function, after the base GPIO & other initializations made by STMCube
2015-03-09T23:20:50 < GargantuaSauce> so we are sure that the gpio is enabled in rcc->ahbenr?

2015-03-09T23:23:40 < GargantuaSauce> yeah as long as you're refreshing often enough i think that's fine
2015-03-09T23:24:16 < ehsanv> GargantuaSauce: the sad point is, i saw a guy who did this with an avr, but the source was in asm and i know asm alot :(

2015-03-10T03:05:51 < zyp> BrainDamage, yeah, I wonder what will happen with that
2015-03-10T03:05:55 < dongs> wanna charge and have  USB device plugged in at same time? tough shit
2015-03-10T03:06:05 < zyp> since USB-C kinda does the same thing
2015-03-10T03:06:23 < zyp> dongs, yeah, that's dumb
2015-03-10T03:06:28 < zyp> although the adapters will allow it
2015-03-10T03:06:35 < BrainDamage> i already had a friend touting it's the way forward

2015-03-10T03:46:18 < sector_0> does anyone know what fCK_PSC is?
2015-03-10T03:46:27 < sector_0> I'm trying to setup a timer
2015-03-10T03:46:54 < sector_0> and I don't quite understand this whole prescaler thing
2015-03-10T03:47:23 < sector_0> the manual says CK_INT is fCK_PSC/(prescaler+1)
2015-03-10T03:47:48 < sector_0> I'm assuming CK_INT is the clock for the timer
2015-03-10T03:48:04 < sector_0> so the edges are taken from CK_INT
2015-03-10T03:48:09 < sector_0> I'm a correct so far?
2015-03-10T03:48:26 < dongs> sounds like just prescaler?
2015-03-10T03:48:33 < dongs> i.e. your timer is clocked off ahb or apb clock
2015-03-10T03:48:45 < dongs> which is then divided by fck_psc
2015-03-10T03:48:49 < dongs> to get y our final freq
2015-03-10T03:50:53 < sector_0> so how do you set fCK_PSC?
2015-03-10T03:51:10 < sector_0> the manual says this "The counter clock frequency (CK_CNT) is equal to fCK_PSC"
2015-03-10T03:51:26 < sector_0> and there's no mention about fCK_PSC anywhere before that
2015-03-10T03:51:26 < dongs> i've not heard of it being called that but when you setup timer timebase you can also set prescaler (divider)...
2015-03-10T03:51:34 < dongs> is this stm32??
2015-03-10T03:51:54 < sector_0> dongs, it's the stm32f4discovery
2015-03-10T03:54:22 < kakeman> there was some trigger controller between timer peripheral clock and fCK_PSC I think
2015-03-10T03:55:35 < sector_0> oops my quote is a bit misleading
2015-03-10T03:55:43 < sector_0> the manual actually says this...
2015-03-10T03:55:50 < sector_0> "The counter clock frequency (CK_CNT) is equal to fCK_PSC / (PSC[15:0] + 1)"
2015-03-10T03:56:06 < sector_0> where PSC is the prescaler register
2015-03-10T03:57:46 < kakeman> all the same
2015-03-10T04:00:21 < kakeman> look at page 511 it says signals, register names and events
2015-03-10T04:00:49 < kakeman> then just bash thru those and timer pages generally
2015-03-10T04:00:57 < kakeman> then just experiment

2015-03-10T06:25:26 < zyp> yeah
2015-03-10T06:25:30 < zyp> I have since read it
2015-03-10T06:26:56 < zyp> oh, by the way, I didn't keep up with irc last week, so I didn't catch what china replied about everything
2015-03-10T06:27:23 < dongs> phy wasnt available
2015-03-10T06:27:49 < zyp> okay, but IIRC digikey has it, so I guess that doesn't matter
2015-03-10T06:28:11 < zyp> what about the connectors?
2015-03-10T06:28:35 < dongs> can't sample cuz oddball size, can produce with some leadtime but its like 1k of htem
2015-03-10T06:28:43 < dongs> 2x13 is really crap size
2015-03-10T06:29:54 < dongs> ill try asking again

2015-03-10T06:30:52 < zyp> hmm
2015-03-10T06:31:43 < zyp> what about 2x15?
2015-03-10T06:33:17 < zyp> I think the board that this is supposed to plug into has shrouded ribbon cable connectors, I guess it'll have room for an additional connection point on either side inside the shroud then
2015-03-10T06:33:31 < zyp> in that case, it'll probably even help alignment
2015-03-10T06:33:42 < dongs> is boss pin really needed
2015-03-10T06:34:04 < dongs> i mean reflow usually takes care of minor misalignment shit
2015-03-10T06:34:49 < zyp> there's two connectors between the boards, and they need to be aligned correctly relative to each other
2015-03-10T06:37:02 < zyp> otherwise I could do PTH, but I want to avoid both the extra assembly step that adds and wasting the area on the top that I could otherwise place parts on
2015-03-10T06:37:13 < dongs> right
2015-03-10T06:37:17 < dongs> kk, reasking agian
2015-03-10T06:38:31 < zyp> or I could keep the dumb old design with ribbon connectors between the boards, but people asked for a module that plugs in directly
2015-03-10T06:42:30 < dongs> http://www.hkjb888.com/en/product.asp?action=detailed&id=1041

2015-03-10T13:06:35 < PaulFertser> C++ seems to be reasonably suited. E.g. if you use it as a strongly typed C, I see no disadvantages.
2015-03-10T13:06:56 < jadew> C is strongly typed
2015-03-10T13:06:59 < jadew> sorry, C++
2015-03-10T13:07:47 < PaulFertser> Yes, unlike C.
2015-03-10T13:07:54 < jadew> C is strongly typed too
2015-03-10T13:07:59 < PaulFertser> Come on!
2015-03-10T13:08:14 < jadew> so that statement translates to "if you use it as C"
2015-03-10T13:08:19 < PaulFertser> In some very weak definition of "strongly", yes. Better than assembly, yes.
2015-03-10T13:08:22 < jadew> or was that the catch and I'm mr. obvious?
2015-03-10T13:08:32 < jpa-> PaulFertser: yes - but it doesn't really fix much
2015-03-10T13:09:06 < jpa-> jadew: nah, it was that you rarely can use C as strongly typed C
2015-03-10T13:09:20 < jpa-> jadew: even just basic malloc() immediately requires you to skip the "strongly typed"
2015-03-10T13:09:27 < PaulFertser> IMHO C++ provides way more type-safety than C. And it also allows to express ideas in a more compact and elegant way. Plus compile-time type-safe code generation with templates (instead of all those macros).
2015-03-10T13:10:00 < PaulFertser> Does "new" in C++ have more overhead than malloc?
2015-03-10T13:10:05 < jpa-> C++ fixes the type safety, yeah; it doesn't fix the buffer overflows and crappy crash modes
2015-03-10T13:11:10 < jadew> jpa-, it sure does
2015-03-10T13:11:18 < jadew> the buffer overflows show up when you do it the C way
2015-03-10T13:11:33 < jpa-> like, myvector[1234]?
2015-03-10T13:11:37 < jadew> yep
2015-03-10T13:11:46 < jpa-> even though that is 100% c++
2015-03-10T13:12:08 < jadew> yeah, I still do it like that, but apparently it's discouraged
2015-03-10T13:14:02 < Laurenceb> Ada then :P
2015-03-10T13:16:26 < jpa-> don't have to go the whole way to ada, plenty of less-typing languages like go, rust, c# solve the problem also
2015-03-10T13:20:03 < jadew> that's a rather radical solution just to get rid of overflows :)
2015-03-10T13:20:03 < jadew> a few simple self-imposed coding standards can take care of it too
2015-03-10T13:20:23 < jadew> and eventually a bit of involved study into array indexes so you don't have to second guess yourself when you're doing math with offsets into the array
2015-03-10T13:23:12 < karlp> rust looked nice.  Tried getting it to run on openwrt though, the runtime was way too big and clunky though. it's not got a chance in hell of being useful for supplanting C at systems level.
2015-03-10T13:24:57 < zyp> there's no reason you couldn't make a container class in C++ with an operator[] that does bounds checking
2015-03-10T13:25:53 < jadew> zyp, I think that's pretty standard
2015-03-10T13:26:13 < zyp> or pointer classes that does bounds checking in the arithmetic operators
2015-03-10T13:26:14 < jadew> the trick is to have the program crash when there's a boundry exception
2015-03-10T13:26:24 < jpa-> and all that just to fix a single case of out-of-bounds access
2015-03-10T13:26:47 < jpa-> eventually you'll get stale pointers and all kinds of other cases
2015-03-10T13:26:56 < zyp> «all that», as opposed to changing language? :p
2015-03-10T13:27:21 < jpa-> karlp: hmm, i thought that there were supposedly possibilities of getting rust reasonably running on microcontrollers also
2015-03-10T13:27:28 < jpa-> zyp: all that, per each project
2015-03-10T13:27:37 < jpa-> when the stl doesn't do that
2015-03-10T13:27:42 < jadew> zyp, you'd use a library
2015-03-10T13:27:45 < jadew> and stl does that
2015-03-10T13:27:59 < jadew> or maybe it doesn't?
2015-03-10T13:28:10 < jpa-> and besides, even if you use a library that does it, a dozen other libraries are not going to do it
2015-03-10T13:28:23 < jadew> either way, I always get a crash when that happens, so whatever is happening in the STL it works
2015-03-10T13:28:27 < zyp> -D_GLIBCXX_DEBUG apparently
2015-03-10T13:28:28 < jpa-> whereas if you pick a safe language, you know that all libraries done in that language behave them atleast that much
2015-03-10T13:29:38 < jadew> jpa-, I agree and I really like the idea of c# which I think is great as a language and extremely well optimized
2015-03-10T13:29:55 < jadew> it's hard to beat even with native coding if you don't know what you're doing
2015-03-10T13:30:07 < jadew> but the problem is that c# comes with a ~400 Mb+ library
2015-03-10T13:30:10 < karlp> http://false.ekta.is/2014/10/rust-on-openwrt-baby-steps/ and the chinese article linked from there
2015-03-10T13:30:39 < karlp> jadew: c# and modern java are both "great, but come with massive runtimes"
2015-03-10T13:30:42 < jpa-> jadew: well there is the micro framework that fits on STM32 easily - but that is not jitted so not as nice
2015-03-10T13:30:57 < zyp> karlp, no, modern java is still useless
2015-03-10T13:31:03 < Laurenceb> heh
2015-03-10T13:31:23 < karlp> zyp: more so than c#? or are you just poking me?
2015-03-10T13:31:25 < zyp> karlp, unless you enjoy dealing with unsigned data in a language without unsigned types

2015-03-10T13:33:35 < jadew> hehe
2015-03-10T13:34:09 < jadew> I think java deserves some appreciation too, but not because of the language itself
2015-03-10T13:34:17 < zyp> anyway, personally I don't find the safety between python and C/C++ a huge distinguishing factor
2015-03-10T13:34:31 < zyp> safety differences*
2015-03-10T13:34:40 < jadew> which seems to be crippled by the very people that are supposed to improve it, but because of the large community behind it which appears to make nice things as of late
2015-03-10T13:35:01 < karlp> zyp: yeah, unsigned is a sucky bit I guess, but in the places I was using java, I was never caring about that.  it was only for bigger things
2015-03-10T13:35:03 < zyp> I just tend to prefer python because it's way less tedious
2015-03-10T13:35:25 < jpa-> zyp: it depends on the application
2015-03-10T13:35:55 < jpa-> zyp: if you consider e.g. user-written decoders that you load inside an application, providing nice debug messages without crashing whole program is quite important

2015-03-10T13:40:39 < zyp> also, speaking of these new modern languages
2015-03-10T13:40:57 < zyp> they seem to do all sorts of weird shit with the syntax, that doesn't seem to have any real benefit
2015-03-10T13:41:32 < jadew> zyp, there's always benefit in flexibility
2015-03-10T13:41:49 < karlp> zyp: "must not look like C, must not look like C"
2015-03-10T13:41:49 < PaulFertser> jpa-: btw, there's mem_helper.tcl and it has mmw proc in it, so you could have used that instead of cooking your own clear/set bits.
2015-03-10T13:41:51 < dongs> you mean like python
2015-03-10T13:42:09 < zyp> dongs, yes, I thought that exact thing befoe I learned python too
2015-03-10T13:42:17 < karlp> "ruby is popular, so was perl, let's use shit loads of symbols all over the place too"
2015-03-10T13:42:26 < jpa-> C# is pretty conservative in syntax; in rust, the syntax changes are quite necessary for the new scoping rules
2015-03-10T13:42:35 < zyp> dongs, it actually kept me away from python the first few times I considered learning it
2015-03-10T13:42:36 < jpa-> ruby is ugly yeah
2015-03-10T13:42:49 < karlp> C# was, "we want to do java, but it can't be _exactly_ like java"
2015-03-10T13:42:50 < jpa-> PaulFertser: ah, good to know
2015-03-10T13:43:08 < karlp> though, I haven't used C# for a while now, they added nullable types and shit since then.
2015-03-10T13:43:10 < jpa-> PaulFertser: i expect that eventually openocd will handle most of it itself
2015-03-10T13:43:42 < jadew> karlp, I think they were like "we want to compete with java, but it has to be good"
2015-03-10T13:43:49 < zyp> I don't consider C# that new
2015-03-10T13:43:52 < jadew> they did a pretty good job with .net
2015-03-10T13:44:35 < zyp> I'm thinking of shit like go

2015-03-10T13:45:00 < jadew> looks like python a bit, no?
2015-03-10T13:45:54 < jadew> oh well, screw all these languages, I'm sticking to c++
2015-03-10T13:46:11 < karlp> jadew: so, you hate java much? :)  Java after java5 should have had a different name, to get away from the baggage of all the java haters
2015-03-10T13:46:14 < jadew> it's cross platform and the easiest language ever, since I know it the best
2015-03-10T13:46:39 < jadew> karlp, don't hate it but I was a bit dissapointed with some things

2015-03-10T13:48:29 < jadew> I did like the override keyword tho and I was super happy to see it part of c++ soon after
2015-03-10T13:48:58 < zyp> I kinda want interfaces in C++
2015-03-10T13:49:18 < jadew> zyp, I thought pure abstract classes are considered interfaces
2015-03-10T13:49:30 < jadew> what kind of interfaces are you talking about?
2015-03-10T13:50:02 < zyp> they are, I just wish they were more explicit about it
2015-03-10T13:50:07 < jpa-> PaulFertser: yeah, we'll see; the tcl scripting was pretty easy anyway
2015-03-10T13:50:37 < jadew> zyp, ah like having a dedicated keyword or something like that?
2015-03-10T13:50:42 < zyp> yes
2015-03-10T13:50:47 < jadew> I guess that would be nice, yeah
2015-03-10T13:51:06 < zyp> using pure abstract classes have dumb gotchas, like forgetting to define a virtual destructor
2015-03-10T13:51:14 < baird> Got $1800, dudes? https://www.apple.com/v/macbook/a/overview/images/internals_layer_end_large.jpg
2015-03-10T13:51:39 < jadew> zyp, I have a bit of OCD so I always ask myself "should this be virtual" when I define a destructor
2015-03-10T13:51:59 < jadew> got bit in the ass by that once and now I'm always thinking about it
2015-03-10T13:52:11 < zyp> jadew, what if you don't define a destructor at all?
2015-03-10T13:52:19 < PaulFertser> Just never inherit from non-abstract classes -> problem solved ;)
2015-03-10T13:52:33 < zyp> PaulFertser, no, it's not
2015-03-10T13:52:41 < jadew> zyp, good point, I suppose the compiler could take care of that by issuing an error
2015-03-10T13:52:48 < jadew> (I wonder if any of them do)
2015-03-10T13:53:42 < jadew> kinda hard to do tho
2015-03-10T13:53:48 < jadew> because you don't always need it
2015-03-10T13:54:05 < jadew> so you could leave it out by design, to preserve performance
2015-03-10T13:54:19 < zyp> the problem is that an object destructed through a parent pointer will call the parent destructor instead of the actual relevant destructor if it's not virtual
2015-03-10T13:54:29 < jadew> yeah
2015-03-10T13:54:52 < zyp> which means that the child destructor doesn't get called at all
2015-03-10T13:55:00 < jadew> but you don't always do that so that's why there's no warning when you inherit from something that doesn't have a virtual destructor
2015-03-10T13:55:07 < jadew> zyp, yes

2015-03-10T13:55:38 < Laurenceb> the comments
2015-03-10T13:56:06 < zyp> jadew, that is correct, the destructor is like any other overridable function in that regard
2015-03-10T13:59:12 < PaulFertser> zyp: if you need dynamic dispatch, yes. But what if you do not, and have templates generate appropriate function for every specific usecase?
2015-03-10T13:59:22 < zyp> interfaces doesn't need to mandate a virtual destructor, but objects should not be destructable through that interface pointer if it's missing
2015-03-10T13:59:29 < zyp> i.e. there should be no default destructor
2015-03-10T14:00:11 < jadew> zyp, how about the case where you have a class inherit the interface and another inheriting from that one
2015-03-10T14:00:13 < zyp> PaulFertser, then you want concepts and not interfaces :)
2015-03-10T14:00:21 < jadew> if one in the chain is missing the virtual keyword you're in the same spot
2015-03-10T14:00:32 < jadew> so the interface keyword wouldn't solve the issue
2015-03-10T14:01:01 < zyp> jadew, what do you mean?
2015-03-10T14:01:03 < PaulFertser> zyp: yes, I want concepts. But concepts mostly help getting sensible error messages when instantiating templates, they're not really needed for code generation, are they?
2015-03-10T14:01:15 < karlp> concepts == composition/mixins? or what?
2015-03-10T14:01:29 < zyp> karlp, template interfaces
2015-03-10T14:01:35 < zyp> http://en.wikipedia.org/wiki/Concepts_%28C%2B%2B%29
2015-03-10T14:01:51 < zyp> it was proposed for C++11 but deemed not ready
2015-03-10T14:02:06 < jadew> interface A { virtual ~A(); }. B : A { ~B(); }. C : B; A * x = new C; delete A;
2015-03-10T14:02:11 < jadew> *delete x;
2015-03-10T14:02:40 < zyp> jadew, that would work perfectly
2015-03-10T14:02:46 < jadew> zyp, it wouldn't
2015-03-10T14:02:52 < jadew> because C's destructor wouldn't get called
2015-03-10T14:03:04 < jadew> it would stop at B
2015-03-10T14:03:06 < zyp> of course it would, C would inherit B's destructor since it has none of it's own
2015-03-10T14:03:15 < jadew> zyp, let's say it does
2015-03-10T14:03:22 < jadew> I just didn't write it in the example
2015-03-10T14:03:28 < zyp> then it'd be virtual
2015-03-10T14:03:35 < jadew> after all they don't contain any data so it wouldn't matter anyway :P
2015-03-10T14:03:41 < PaulFertser> Once virtual, the function is virtual in all the inherited classes too, automatically.
2015-03-10T14:03:43 < jadew> zyp, yes, B would have to be virtual
2015-03-10T14:03:47 < zyp> what PaulFertser said
2015-03-10T14:04:02 < zyp> the problem is not in that direction
2015-03-10T14:04:24 < zyp> child classes always know what the parent classes have, and satisfies the same
2015-03-10T14:04:26 < jadew> actually, I guess you could check the "virtual" constrain when the compiler checks the validity of C
2015-03-10T14:04:34 < jadew> by seeing that A is an interface
2015-03-10T14:04:46 < zyp> when B have a vtable entry for the destructor, C will use it
2015-03-10T14:04:50 < jadew> so all the classes between A and C have to have virtual destructors
2015-03-10T14:04:52 < jadew> yeah, that would work
2015-03-10T14:05:35 < zyp> the problem is when A have no vtable entry for the destructor, and you try to delete a class through a pointer to A
2015-03-10T14:05:47 < jpa-> hm, this 3G modem has a millisecond parameter, 20-500 ms, for nagle algorithm - does anyone know what that might correspond to?
2015-03-10T14:05:52 < zyp> then it wouldn't be able to delete the class, even though B or C adds one
2015-03-10T14:06:31 < zyp> http://en.wikipedia.org/wiki/Nagle%27s_algorithm <- this, I guess
2015-03-10T14:07:37 < jpa-> yes, i know the algorithm
2015-03-10T14:07:41 < zyp> I guess it's how long you wait for the buffer to fill before you pack it up and send it
2015-03-10T14:08:02 < jpa-> hmm, so it would be for transmission only?
2015-03-10T14:08:11 < karlp> "tweak this knob until perforamnce doesn't suck as much as before, turn it in both directions, it's hard to say what you'll need"
2015-03-10T14:08:16 < jpa-> makes sense
2015-03-10T14:08:21 < zyp> well, it's a tx algorithm
2015-03-10T14:08:24 < jpa-> yeah
2015-03-10T14:08:32 < zyp> but this is just guesswork of course
2015-03-10T14:08:34 < jpa-> i somehow confused it with the other tcp "sliding window" things
2015-03-10T14:08:39 < karlp> UDP blast all the things.
2015-03-10T14:08:49 < karlp> TCP, it sucks, but it sucks fairly!
2015-03-10T14:08:52 < jpa-> i only care about RX speed, so tuning that particular knob will not help in that case

2015-03-10T17:12:36 < Steffanx> but for my understanding. Your issue means that the extruder is still moving for x milliseconds ( so pushing out filament) while the x/y/z axis already stopped?
2015-03-10T17:12:52 < Steffanx> "stopped"
2015-03-10T17:13:00 < Steffanx> they can't suddenly stop ofcourse
2015-03-10T17:13:15 < jpa-> yeah
2015-03-10T17:13:32 -!- bsdfox [~h36sa@freebsd/contributor/bobryan] has quit [Ping timeout: 246 seconds]
2015-03-10T17:13:39 < jpa-> basically because the extruder speed/acceleration is calculated to match x/y/z speed, but there is rounding errors
2015-03-10T17:13:48 < jpa-> so they do not finish at exactly the same time
2015-03-10T17:14:11 < Steffanx> i get it now
2015-03-10T17:14:27 < GargantuaSauce> are you sure it's that? even if the extruder stops at exactly the "right" time the plastic in the nozzle will still be under pressure and it'll keep extruding a bit unless you reverse the extrusion drive
2015-03-10T17:16:10 < jpa-> GargantuaSauce: nah the problem is totally software
2015-03-10T17:16:20 < jpa-> it makes a pause in the stepper driving because it waits for extruder
2015-03-10T17:16:27 < jpa-> which causes lost steps because it does not decelerate
2015-03-10T17:16:43 < Steffanx> didn't you read the essentialcrap tip GargantuaSauce?

2015-03-10T17:23:27 < Laurenceb> jpa-: is it using all floating point?
2015-03-10T17:24:24 < jpa-> Laurenceb: no, it uses fixed point (IIRC 8.14 or something) for the acceleration
2015-03-10T17:24:42 < Laurenceb> oh
2015-03-10T17:24:52 < Laurenceb> so its just out by 0ne lsb?
2015-03-10T17:25:02 < Laurenceb> or does it accumulate more than that?
2015-03-10T17:25:19 < jpa-> i think it accumulates.. the extruder is controlled separately so i think timing can affect it also
2015-03-10T17:25:57 < jpa-> my first fix was to fix it so that it can happily accumulate over many moves :D
2015-03-10T17:26:28 < Laurenceb> maybe you could ignore the waiting?
2015-03-10T17:26:43 < Laurenceb> or will the error get gradually worse over time?
2015-03-10T17:27:04 < jpa-> yeah, that is exactly the way to make it accumulate over many moves
2015-03-10T17:27:14 < Laurenceb> eww nasty
2015-03-10T17:27:35 < Laurenceb> maybe some sort of filter would help
2015-03-10T17:27:40 < jpa-> but it recalcs acceleration every 1 ms anyway, i think i can do something there
2015-03-10T17:27:51 < Laurenceb> i havent a clue how the control works lol
2015-03-10T17:27:52 < Laurenceb> yeah
2015-03-10T17:27:59 < jpa-> like make it check "are we falling behind other axes" and then +1 to the speed
2015-03-10T17:28:01 < Laurenceb> id have though you could add a correction there
2015-03-10T17:28:17 < jpa-> yeah, pretty sure i can - just have to figure out what kind of correction :D
2015-03-10T17:28:41 < Laurenceb> i wrote acceleration based linear actuator control for my arm prodder project, but it was only single axis

2015-03-10T22:35:07 < sector_0> is there a way to yield the processor on an STM32F4?
2015-03-10T22:36:11 < Steffanx> uhm, what do you want it to do?
2015-03-10T22:36:30 < ehsanv> hi. want to build a usb device that receive 16byte request and send multibyte(unlimited in length, if possible, or selectable up to 1MB) as return. is this possible with Custom HID?
2015-03-10T22:37:43 < Fleck> https://www.youtube.com/watch?v=eYa03jGOAHk
2015-03-10T22:39:21 < sector_0> Steffanx, I have a timer ISR that drives a GPIO pin, and I have a function that setup the parameters necessary to drive that pin
2015-03-10T22:40:00 < sector_0> but I want to be able to set multiple parameters from that function and wait for the timer ISR to process those parameters as they are setup
2015-03-10T22:41:15 < sector_0> so I want to do something like this "set variable...wait for timer to tick....process the variable from the timer ISR...return back to my function and set another variable"
2015-03-10T22:41:29 < sector_0> then rise and repeat until the loop expires
2015-03-10T22:41:52 < sector_0> ...the more I explain this the more it seem unachievable...is this possible?
2015-03-10T22:44:05 < ehsanv> sector_0: you may use a global variable for both functions(ISR and your current running function), set that variable to '1' that mean 'to process' and {while(variable == 1) delay; } i mean wait for variable to change
2015-03-10T22:44:28 < ehsanv> sector_0: the variable will change after ISR function done his/her job :)
2015-03-10T22:44:50 < ehsanv> something like mutex's
2015-03-10T22:45:15 < ehsanv> LOCK and UNLOCK feature
2015-03-10T22:46:10 < ehsanv> sector_0: i think i explain it bad lol, do you understand what i'm saying?!?!
2015-03-10T22:46:55 < sector_0> ehsanv, lol I know what you mean
2015-03-10T22:47:10 < sector_0> and thanks for the suggestion, I didn't even think of that
2015-03-10T22:47:51 < ehsanv> sector_0: you're welcome :)
2015-03-10T22:48:45 < Steffanx> then you can almost get rid of the isr handler and wait for the flag...
2015-03-10T22:48:53 < ehsanv> anyone experience with USB programming?! my english is not that good and i confused with technical details about usb :( just want a simple request and send system!
2015-03-10T22:54:43 < sector_0> that doesn't work..
2015-03-10T22:55:16 < sector_0> when I do "while(flag){ __asm("nop"); }"..the ISR is never called
2015-03-10T22:56:34 < sector_0> Steffanx, and the operations need to be timed so I can't get rid of the timer, and besides waiting for a flag without an interrupt is most certainly going to get me stuck in a loop
2015-03-10T23:00:12 < ehsanv> sector_0: do a more time consumer task inside while, if your timer isn't so fast. like HAL_Delay() or a for loop. see if it works

2015-03-10T23:01:20 < ehsanv> sector_0: or check your pin toggle status for flag, if timer toggles a pin.
2015-03-10T23:01:54 < ehsanv> sector_0: for example save previous state of pin, and while(pin change);
2015-03-10T23:02:15 < ehsanv> i mean while(!pin change);

2015-03-11T06:07:19 < ds2> useful no doubt...understandable... takes time to get there
2015-03-11T06:07:52 < ds2> next thing after this is understanding why it is sometimes optimal to decimate in steps
2015-03-11T06:09:48 < emeb_mac> ds2: you can decimate in large steps with CIC, but the response isn't great
2015-03-11T06:10:08 < ds2> hmmm?
2015-03-11T06:10:10 < emeb_mac> I like to do "coarse" decimation with CIC followed by fine decimation with FIR
2015-03-11T06:10:29 < ds2> things I am finding suggests it is optimal (computation wise) to do it in steps if the decimation is large enough
2015-03-11T06:11:00 < emeb_mac> If you do FIR decimation then there are advantages in complexity to doing it in steps
2015-03-11T06:12:05 < emeb_mac> similar to what I mentioned above w/ CIC, you can use crude FIRs for the up-front steps
2015-03-11T06:12:10 < ds2> from the graphs I am seeing, it'd SEEM like one huge decimation with a large number of CIC taps would seems to be the easiest
2015-03-11T06:12:35 < emeb_mac> ds2: that is easy, but the frequency response of a CIC isn't great
2015-03-11T06:12:58 < emeb_mac> so you do *most* of the decimation with CIC, then a "cleanup" with a nicer FIR
2015-03-11T06:14:45 < ds2> emeb_mac: but for a large number of taps, the CIC filter seems fine
2015-03-11T06:14:53 < ds2> let me pull up the graph I am talking about
2015-03-11T06:15:27 < ds2> http://www.analog.com/media/en/technical-documentation/dsp-book/dsp_book_Ch15.pdf
2015-03-11T06:15:41 < ds2> page 4, figure 15-2
2015-03-11T06:16:35 < ds2> going from like 20MHz down to 8KHz should imply a huge number of points which suggests the lobes would all but go away
2015-03-11T06:19:34 < emeb_mac> ds2: the problem with that chart is that it's linear scale in the Y axis
2015-03-11T06:20:44 < emeb_mac> that 1st sidelobe is only 0.2, but that's like -14dB
2015-03-11T06:20:55 < emeb_mac> not a lot of rejection
2015-03-11T06:21:13 < ds2> that first sidelobe seems to go down dramatically as the number of points increase
2015-03-11T06:21:18 < ds2> is this not true?
2015-03-11T06:21:34 < emeb_mac> not enough for a sharp filter response

2015-03-11T06:21:52 < emeb_mac> plus, with a high decimation ration it aliases back into the passband
2015-03-11T06:22:00 < ds2> or are you trying to tell me it is a relative constant -14dB down?
2015-03-11T06:22:27 < ds2> 'k... let me study more
2015-03-11T06:22:29 < emeb_mac> no, you're right - the 1st sidelobe rejection does increase with higher orders of filters, but it's still pretty high
2015-03-11T06:23:01 < emeb_mac> I've done CICs with decimation ratios approaching 1k
2015-03-11T06:23:07 < ds2> okay. assuming I am starting with 8bit data
2015-03-11T06:23:22 < ds2> isn't anything more then -48dB down moot?
2015-03-11T06:23:22 < emeb_mac> and I still found a cleanup filter to be a big improvement - especially in getting rid of suprious response.
2015-03-11T06:23:36 < emeb_mac> ds2: for RF - you often want much more
2015-03-11T06:23:47 < ds2> more bits or more rejection?
2015-03-11T06:23:53 < emeb_mac> one decimator I did was > 100dB down in the stopband
2015-03-11T06:24:04 < emeb_mac> for a VHF aircraft receiver
2015-03-11T06:24:47 < ds2> how can it be 100dB down if the original data only has less range then that?
2015-03-11T06:25:01 < emeb_mac> ds2: that's the magic of integration
2015-03-11T06:25:21 < emeb_mac> when you decimate you pick up additional bits of resolution for every factor of 4
2015-03-11T06:25:38 < emeb_mac> so when I decimated by 1k, I picked up 5 bits
2015-03-11T06:25:42 < ds2> Ohhh this is that oversampling gain thingie?
2015-03-11T06:25:47 < emeb_mac> yep
2015-03-11T06:26:28 < emeb_mac> so if you start with a 10-bit ADC, you get 15 bits out with a 1k ratio

2015-03-11T06:26:53 < ds2> but 15bits is only about 90db of range
2015-03-11T06:26:59 < emeb_mac> and that's a BIG help when you're working with weak signals
2015-03-11T06:27:24 < emeb_mac> well, the 100dB system I did started with a 14-bit ADC
2015-03-11T06:27:35 < ds2> oh okay
2015-03-11T06:28:06 < ds2> so if the input is 10bit ADC, a 1K ratio decimation would only require about 90dB of stopband (due to limited range of the data)?
2015-03-11T06:28:34 < emeb_mac> "require" isn't a good way to say it.
2015-03-11T06:28:50 < ds2> hmmm?
2015-03-11T06:29:05 < emeb_mac> you wouldn't want to provide more than 90dB because the available dynamic range wouldn't support it.
2015-03-11T06:29:23 < emeb_mac> ie - you could make a filter with more rejection, but it wouldn't buy you anything.
2015-03-11T06:29:50 < ds2> gotcha
2015-03-11T06:30:06 -!- DLPeterson [~hazelnuss@c-67-188-127-70.hsd1.ca.comcast.net] has quit [Quit: leaving]
2015-03-11T06:30:14 < emeb_mac> you start with the sensitivity & dynamic range spec, then choose the ADC based on that.
2015-03-11T06:30:37 < ds2> so working backwards, an 8bit ADC wouldn't benefit from more then about 78dB of rejection for the same 1K ratio
2015-03-11T06:30:46 < emeb_mac> so for example, in the VHF radio I did we needed at least 90dB of adjacent channel rejection
2015-03-11T06:31:03 < emeb_mac> so we speced a 100dB filter and then that determined the ADC we needed.
2015-03-11T06:31:23 < ds2> *nod* I understand I am working it in reverse
2015-03-11T06:31:37 < emeb_mac> ah - your ADC is already fixed
2015-03-11T06:31:41 < ds2> helps with understanding things when I can juggle the numbers around
2015-03-11T06:31:54 < emeb_mac> so you try to figure out what that supports
2015-03-11T06:32:52 < ds2> this entire discussion helps me understand the numbers come from somewhere. when you first said 100dB, it sounded like it was an arbitrary spec
2015-03-11T06:33:24 < emeb_mac> You're right - the specification comes from the signal environment
2015-03-11T06:33:55 < emeb_mac> for example, VHF aircraft receivers need a certain sensitivity, but the adjacent channels can be very strong.
2015-03-11T06:34:35 < emeb_mac> so if you are in channel X listening to a far-away source, but there's a strong nearby signal in X+1 then you want good rejection.
2015-03-11T06:34:39 < ds2> and that precludes playing games with switchable attenuators/preamps in the front end, right?
2015-03-11T06:34:51 < emeb_mac> right
2015-03-11T06:35:27 < emeb_mac> because if you attenuate the strong signal, you hurt the weak one too if you do it prior to the selectivity filter
2015-03-11T06:36:15 < ds2> got it. pure analog systems would solve that with a preselection filter
2015-03-11T06:36:18 < emeb_mac> you need to leave the front-end as wide-open as possible to allow tuning.
2015-03-11T06:37:33 < emeb_mac> Even analog systems can't use preselectors for ACR if the adjacent channel is one you might want to tune to.
2015-03-11T06:37:43 < emeb_mac> in that case they use tracking filters
2015-03-11T06:37:54 < emeb_mac> which is very similar to multi-step decimation.
2015-03-11T06:40:36 < ds2> it is?
2015-03-11T06:40:54 < ds2> thought a tracking filter is another tank circuit that follows the signal you want
2015-03-11T06:43:37 < emeb_mac> it's a bit of a stretch I'll admit

2015-03-11T07:08:15 < PeterM> for low currents its fine but high currents inducto would be pretty big, especially wiht big delta out

2015-03-11T07:08:41 < dongs> highest is like 10V @ 400mA
2015-03-11T07:08:42 < PeterM> yeah thats no worreis then
2015-03-11T07:10:46 < dongs> the internet informed me higher Vin and higher switching frequency leads to shittier efficiency too
2015-03-11T07:11:03 < PeterM> it depends
2015-03-11T07:11:26 < PeterM> you trade higher switching losses for lower magnetics losses
2015-03-11T07:14:37 < PeterM> at higher powers though this is rpetty redundant though - you just use multipahse systems, so you run at lower switching freqs, but you use small inductors, then interleavehing cycles to output ripple is low

2015-03-11T15:46:36 < yots> hmm this is completely stupid, but for anyone using Eclipse for remote debugging - can you think of a reason for why the "restart target" is now permanently disabled for me?
2015-03-11T15:46:50 < yots> everything else works
2015-03-11T15:47:39 < yots> it may be specific to the j-link plugin, i don't usually use eclipse
2015-03-11T15:48:00 < PaulFertser> yots: using "remote" instead of "extended-remote" protocol for gdb target.
2015-03-11T15:49:07 < kakeman> what is example application for remote debuging?
2015-03-11T15:49:50 < PaulFertser> kakeman: debugging firmware running on an stm32-based board
2015-03-11T15:50:33 < yots> remote as in not running the program inside GDB but using a gdbserver
2015-03-11T15:50:50 < yots> thanks PaulFertser, i'll try and see if anything like that had changed
2015-03-11T15:51:58 < kakeman> but why it's needed to be remote?
2015-03-11T15:53:42 < yots> because my local x86 machine cannot perform ARM instructions?

2015-03-11T15:55:35 < kakeman> now I understand
2015-03-11T15:55:59 < kakeman> I supposed remote means you have target over ethernet or so
2015-03-11T15:57:57 < yots> in gdb terminology remote is anything that isn't executed locally and requires a gdbserver, doesn't matter if it's running inside a VM/ran by a j-tag support software/is over the ocean over IP

2015-03-11T16:47:49 < dongs> At 9.45am this morning we ordered the full production panels for the top board and for the flight frame. These are full production versions with all the latest parts, amendments, power supply updates, beefed up motor controllers (200% the capacity of the prototype). We ordered enough panels to build hundreds of Zano's and right now we are on track to the day to our schedule.

2015-03-11T16:55:16 < dongs> The noise was introduced by a new component that was not on the prototype and the noise was not expected. Once I identified where the noise was coming from, we have made a simple modification to the pre-production Zano's we have here and tested the solution. This solution has also been implement for the production version.

2015-03-11T18:05:08 < dongs> We have a final working prototype, but it cost five times more to get to this point than we had planned for, and will cost three times more to manufacture per unit than we had hoped.

2015-03-11T18:06:29 < jadew> apparently they didn't do any of the work, they just subcontracted everything

2015-03-11T18:16:01 < dongs> they have something very fuzzy at the end of one of thier update videos
2015-03-11T18:16:05 < dongs> that looks different shape
2015-03-11T18:16:07 < jadew> then I guess it doesn't fly yet
2015-03-11T18:16:08 < dongs> and just kinda wobbles around
2015-03-11T18:17:03 < jadew> you'd expect that to be the first thing you try to get right before even starting this project

2015-03-11T18:19:27 < Getty> <facepalm>, now this device gets 2 different IPs depending on whatever
2015-03-11T18:19:40 < Getty> you make a firmware upgrade and next boot it got a different IP from DHCP
2015-03-11T18:19:43 < Getty> but always the same 2
2015-03-11T18:20:26 < qyx_> how do you allocate your mac addresses?

2015-03-11T18:21:24 < jadew> where?
2015-03-11T18:21:27 < dongs> zano?
2015-03-11T18:21:27 < karlp> anyone know of a C test framework that lets me do stuff like this: https://pastee.org/8far2 but doesn't give me unhelpful line numbers for the failure that are always in the shared complex comparision helper function?
2015-03-11T18:21:42 < dongs> all their 'desks' are taken inside some empty fucking office
2015-03-11T18:22:14 < jadew> karlp, for c++ there's boost test
2015-03-11T18:22:16 < Getty> qyx_: i have an i2c mac chip
2015-03-11T18:22:31 < _Sync_> yeah zano
2015-03-11T18:22:51 < karlp> Getty: are you sending a client id or anything?
2015-03-11T18:23:03 < _Sync_> although they have an okay scope
2015-03-11T18:23:05 < karlp> windows is pretty good at being shit and not giving you a stable ip.
2015-03-11T18:23:21 < Getty> yeah i send a hostname, but then it should it be like 10< different ips that it should rotate with (as all of them have the same hostname)
2015-03-11T18:23:38 < Getty> its a fritzbox dhcp
2015-03-11T18:23:55 < jadew> Getty, maybe the DHCP server always has that one IP free
2015-03-11T18:23:55 < karlp> it's recommended practise to keep them stable, but there's no _requirement_ to keep them stable :)
2015-03-11T18:24:04 < jadew> then, when you disconnect and re-connect
2015-03-11T18:24:08 < jadew> the lease for that one is already given
2015-03-11T18:24:13 < jadew> so you end up with a new IP
2015-03-11T18:24:22 < qyx_> wut
2015-03-11T18:24:27 < jadew> once that happens, it sees the same MAC address has another, older lease and removes it
2015-03-11T18:24:27 < qyx_> why should it rotate them?
2015-03-11T18:24:40 < jadew> when you reconnect again, you get back to the first free IP

2015-03-11T18:25:35 < Getty> i dont said it might be related, i delivered an argument why it cant be related to any client identification given

2015-03-11T18:27:14 < Getty> so far i just pointed out that it happens, and wireshark in this case could show nothing but the situation given: that the dhcp gives back those IPs ;)
2015-03-11T18:27:30 < Getty> i will first debug the mac address, if there is any "bug"
2015-03-11T18:27:57 < qyx_> what about first see what is *really* flowing through the network
2015-03-11T18:28:01 < qyx_> rather than guessing?
2015-03-11T18:28:16 < _Sync_> how the fuck are they putting all that shit into 55g
2015-03-11T18:28:25 < Getty> the machine itself has nos torage of the previous IP, the IP given MUST be from the DHCPd
2015-03-11T18:28:27 < _Sync_> I don't really buy that
2015-03-11T18:29:10 < Getty> or i have 2 dhcpd running ;) huehue
2015-03-11T18:29:12 < qyx_> Getty: there are multiple different cases how you can discover/request/deny the offered address
2015-03-11T18:29:14  * Getty thinks now
2015-03-11T18:30:45 < Getty> yeah of course, the next 10 reboots it didnt switched the ip
2015-03-11T18:31:23 < Getty> i had that 3 times in a row on my tester script.... but when you look at it, of course it hides in the closet

2015-03-12T00:31:12 < emeb> However, I've got another Em::Blocks project that uses very similar code that doesn't have this problem.
2015-03-12T00:32:01 < emeb> I guess the trick is to find the differences, eliminate them until either the working one breaks or the broken one works.

2015-03-12T01:33:31 < KreAture_> for example there is no proper checking in the libs so you can easily overwrite data you are trying to send
2015-03-12T01:33:49 < KreAture_> There are other issues too regarding when to send zlp's etc
2015-03-12T01:34:04 < KreAture_> You may end up with host waiting forwver and you already sendt data and wait too etc

2015-03-12T02:01:43 < qyx_> i mean when i have defined some synchronization mechanism for a shared structure

2015-03-12T02:01:53 < qyx_> and access it from two threads without locking
2015-03-12T02:02:24 < qyx_> but only one thread writes the data and marks them as valid setting some bool to true
2015-03-12T02:02:43 < qyx_> and the second thread reads them only if it sees the bool variable set to true
2015-03-12T02:02:44 < KreAture_> emeb just remember if you ever get hardfaults on the A, switch to the Z
2015-03-12T02:02:54 < KreAture_> don't waste time like I did
2015-03-12T02:03:04 < qyx_> and those two things happen in different functions
2015-03-12T02:03:13 < qyx_> is there a need to mark them volatile?
2015-03-12T02:03:31 < qyx_> how "broadly" tries the compiler optimize such things?
2015-03-12T02:03:57 < KreAture_> volatile helps to make sure a call does not cache the value
2015-03-12T02:04:36 < qyx_> yes, but i don't care if it changes inside a function
2015-03-12T02:04:43 < qyx_> *of
2015-03-12T02:04:49 < KreAture_> since cointext switching in some embedded os'es happen without compilers pre-knowledge you will end up with a optimized thread stashing away it's values on stack and other thread running with it's own
2015-03-12T02:04:57 < KreAture_> so you will need to volatile it
2015-03-12T02:05:06 < qyx_> ok, missed that, good point
2015-03-12T02:05:55 < KreAture_> Otherwise the threads may do lazy access and cache
2015-03-12T02:05:58 < KreAture_> :)
2015-03-12T02:05:59 < qyx_> but the only bac thing that could happen in this scenario is that the reading thread would miss the variable being set to trie
2015-03-12T02:06:06 < qyx_> *bad
2015-03-12T02:06:14 < KreAture_> well, depends on how atomic the read is
2015-03-12T02:06:18 < qyx_> *true, damn typing
2015-03-12T02:06:32 < KreAture_> if you use atomic_read type stuff on the other value after seeing the true it is ok
2015-03-12T02:07:08 < KreAture_> since it would not matter if someone sets it to "more true" after it has checked it and decded to read it will be fine to only use the call for the actual access
2015-03-12T02:07:11 < qyx_> better mark them all volatile
2015-03-12T02:07:21 < KreAture_> and it is usually only needed for variables larger than your platform native
2015-03-12T02:07:53 < KreAture_> aka a 32 bit platform I think it is safe to access the 32 bit stuff but not 64 bit stuff without a atomic read type macro

2015-03-12T02:09:43 < KreAture_> That will synch your threads unless it can't wait

2015-03-12T02:10:07 < qyx_> or maybe yes
2015-03-12T02:10:45 < KreAture_> often it is better than using criticalsection
2015-03-12T02:10:59 < KreAture_> as criticalsection screws up more isrs
2015-03-12T02:11:02 < KreAture_> usually
2015-03-12T02:11:08 < qyx_> critical section is not applicable here
2015-03-12T02:11:21 < qyx_> because i would need to use it around writes and reads
2015-03-12T02:11:32 < KreAture_> well it can be as you can use criticalsection to avoid os context switching in the middle of your read

2015-03-12T02:12:23 < KreAture_> you need to cache it locally
2015-03-12T02:12:27 < KreAture_> then do your 500ms thing

2015-03-12T04:47:06 < emeb_mac> nothing wrong with the colors
2015-03-12T04:47:18 < emeb_mac> with OSHpark you get purple and pink. oh well
2015-03-12T04:49:02 < emeb_mac> what's the bga?
2015-03-12T04:50:27 < emeb_mac> fun!
2015-03-12T04:51:17 < emeb_mac> what's wrong with atmel?
2015-03-12T04:52:36 < emeb_mac> that's handy
2015-03-12T04:52:47 < emeb_mac> series or parallel?
2015-03-12T04:53:27 < emeb_mac> ya - parallel might dissipate too much power at 3.3V
2015-03-12T04:54:37 < emeb_mac> yes - hard to have a good match on small values in most semiconductor processes
2015-03-12T04:59:23 < emeb_mac> pretty well
2015-03-12T04:59:45 < emeb_mac> got the BBB form-factor STM32 board almost completely tested out.
2015-03-12T05:00:04 < emeb_mac> it interfaces correctly to the Spartan6 FPGA board
2015-03-12T05:00:11 < emeb_mac> Beaglebone
2015-03-12T05:00:37 < emeb_mac> So next thing is to hook it to the ADS-B receiver
2015-03-12T05:00:49 < emeb_mac> see if that works better than the Beaglebone
2015-03-12T05:01:36 < emeb_mac> got some other digital radio projects that I want to try with it
2015-03-12T05:02:25 < emeb_mac> any joy?
2015-03-12T05:03:19 < emeb_mac> Tanner?
2015-03-12T05:05:05 < emeb_mac> that'll do it
2015-03-12T05:05:29 < emeb_mac> wonder if there are any FOSS chip design tools?

2015-03-12T05:06:25 < emeb_mac> What's Electric?
2015-03-12T05:06:48 < emeb_mac> any good?
2015-03-12T05:08:55 < emeb_mac> ya - reading the Wikipedia article
2015-03-12T05:09:01 < emeb_mac> non-standard design flow
2015-03-12T05:09:04 < emeb_mac> not poly-based
2015-03-12T05:09:37 < emeb_mac> that's what it says
2015-03-12T05:12:12 < emeb_mac> gonna try it?
2015-03-12T05:12:37 < emeb_mac> what foundry would you use?
2015-03-12T05:12:42 < emeb_mac> mosis?
2015-03-12T05:13:39 < emeb_mac> too bad chip processing is so $$$
2015-03-12T05:16:07 < BrainDamage> but, you'd be passing down a chance to infuriate dongs
2015-03-12T05:16:22 < BrainDamage> doing some more or less serious work with an open source tool
2015-03-12T05:17:10 < dongs> what's r2com fabbing
2015-03-12T05:17:12 < dongs> buttcoin asic?
2015-03-12T05:21:13 < dongs> As an indication of the complexity of Electric, this circuit consumes 1.4 megabytes of disk space. Although this is not small, it does contain more information than typical design databases. It can be read in 50 seconds and written in 30 seconds (on a SUN/3 workstation). Netlist generation takes only 15 seconds (these figures were compiled in 1986, when computers were significantly slower).
2015-03-12T05:22:08 < emeb_mac> heh

2015-03-12T05:33:01 < upgrdman> noob question: in altium, if you make a schematic symbol, it can have multiple "components" ... why?
2015-03-12T05:34:01 < upgrdman> oh ok. so just to make things more readable than one long rectangle for hundrens of pins/pads?

2015-03-12T08:14:36 < emeb_mac> but the semihosting difference was a red herring
2015-03-12T08:14:56 < emeb_mac> the actual difference was that the working code had the right buffer sizes.

2015-03-12T10:18:42 < Getty> ok today i learned, a malfunction windows machine can actually kill network segments..... over night.... randomly
2015-03-12T10:19:50 < Getty> my complete network (router => switch => switch => switch => my pc) was unreachable, after switching like... _ALL_ the switches the problem was still "half" there (like last switch was not there)
2015-03-12T10:20:20 < Getty> till i noticed one flickering light on it and that was the unused windows station which just runs.... switched it off => network back
2015-03-12T10:22:00 < Getty> i dont even have any idea how he made it over 3 switches and killed there the complete segmnet
2015-03-12T10:22:03 < Getty> noone was able to reach anybody
2015-03-12T10:23:03 < zyp> packet storm?
2015-03-12T10:23:45 < Getty> but still going over 3 switches and overloading all priority?
2015-03-12T10:23:52 < Getty> i mean we talk about that ping said unreachable ;)
2015-03-12T10:24:06 < zyp> you know, making a loop in a segment is also enough to kill it, since frames will be duplicated over and over
2015-03-12T10:24:15 < Getty> yeah sure! but i was sleeping
2015-03-12T10:24:29 < Getty> i woke up to offline network, and after restart first switch it was fine again... for 10 minutes
2015-03-12T10:24:41 < Getty> and after REPLACING the switches it was "half gone", half the room had perfect network again
2015-03-12T10:24:54 < Getty> if it would be a common flood it should have been go on
2015-03-12T10:25:20 < Getty> eve.n tho i still cant imagine a "common" flood that really kills it all so massivly, chaos yeah, but unreachable?... thats so hardcore

2015-03-12T10:25:51 < Getty> i hopeits noit related to my arm ;)
2015-03-12T10:26:15 < yots> turn it back on to find out!
2015-03-12T10:27:24 < Getty> i dont feel todo so ;)
2015-03-12T10:27:50 < Getty> a so deadly big flood also cant be analyzed, i mean i woudlnt be able to act while it happened
2015-03-12T10:27:58 < Getty> no idea how to debug this... wireshark will for sure not work anymore ;)
2015-03-12T10:28:16 < Getty> wireshark would bail out with "no network connected"
2015-03-12T10:28:23 < Getty> cause that is what the hardware reports ;)
2015-03-12T10:28:39 < Getty> thats why i mean: i have never ever seen something like that
2015-03-12T10:28:59 < Getty> it must be a loop, but..... over night? 8-) i dont know... i just dont know
2015-03-12T10:29:22 < jpa-> cheap routers/switches can overheat from traffic
2015-03-12T10:29:53 < Getty> yeah thats why i replaced them all, which leaded to this "lowering" of the problem, which definitly fits "a bit"
2015-03-12T10:30:19 < Getty> but it would be awkward that replace cheap A with cheap B really solved the problem somehow
2015-03-12T10:30:29 < Getty> <shiver> network is fun

2015-03-12T12:43:58 < Getty> ok i am very very certain that there is "some little" problem with the network i do
2015-03-12T12:44:15 < Getty> its like... customer reports now that he doesnt get any IP if he has a switch between the router and the device
2015-03-12T12:45:21 < Getty> same device on router, gets it, he has more device on the switch (TV and stuff) and all works, i also dont think its "directly" related to the switch, but it reveals a problem (and 2-3 QA-failing ones that chuckle specific on network might also be a sign)
2015-03-12T12:46:28 < yots> ok, so i still haven't figured it out. i'm using eclipse with the j-link plugin and the Restart target button is grayed out. it used to work perfectly
2015-03-12T12:46:53 < yots> of course running gdb manually and doing a "mon reset" works

2015-03-13T04:08:25 < ds2> the integrated notification/IM system is just perfect

2015-03-13T04:08:27 < zyp> I've found that android is okay if you just avoid all the bullshit
2015-03-13T04:08:35 < kakeman> and windows.. goes windows way
2015-03-13T04:08:41 < ds2> got to remember - Android is not made for you the user
2015-03-13T04:08:59 < ds2> Android is made to steal as much money/information/etc from the user for the manufacture

2015-03-13T04:13:40 < ds2> PeterM: still do.
2015-03-13T04:14:01 < PeterM> i went through a few usb ports and was liek fuck it
2015-03-13T04:14:22 < ds2> I really like how different IM protocols just appear exactly the same

2015-03-13T04:15:10 < kakeman> I actually have one n900 in storagebox
2015-03-13T04:15:16 < ds2> well... ctrl-c....
2015-03-13T04:15:23 < ds2> kakeman: is it working and for sale?
2015-03-13T04:15:31 < kakeman> working yes
2015-03-13T04:15:51 < PeterM> also its camera was surprisingly good
2015-03-13T04:15:55 < ds2> good to have spare parts
2015-03-13T04:16:04 < kakeman> drained battery really quick though
2015-03-13T04:16:23 < kakeman> didn't take more look at it
2015-03-13T04:16:31 < ds2> battery life isn't bad provided I don't blast a ton of data through it
2015-03-13T04:16:44 < kakeman> some firmware issue seller said
2015-03-13T04:16:47 < BrainDamage> one thing i wonder is why the fuck there's no integrated messanging interfaces in a phone where programs just plug in
2015-03-13T04:16:55 < BrainDamage> rather than everyone reinventing the wheel
2015-03-13T04:17:00 < ds2> doing the same things on Android is downright frustrating

2015-03-13T12:11:05 < dongs> hah no
2015-03-13T12:11:18 < dongs> i turned that R62N shit from baird once
2015-03-13T12:11:23 < dongs> saw it tried to do some IoT shit
2015-03-13T12:11:25 < dongs> and turned it off again
2015-03-13T12:11:30 < dongs> turned on
2015-03-13T12:12:43 < zyp> I found some small 20-pin renesas chip inside some shit, just curious how it works
2015-03-13T12:13:58 < zyp> there's a «mode» pin broken out, datasheet only says «Connect this pin to VCC via a resistor»

2015-03-13T12:21:45 < zyp> would be neat if I could dump the firmware for this shit, but I assume it's read protected anyway, so I'm not going to waste my time trying to figure out how

2015-03-13T12:50:16 < dongs> but rendered per pixel

2015-03-13T13:30:50 < jpa-> hmm, is there any nice way to force gcc to generate a breakpointable line? asm volatile("nop"); is the nicest i have found so far, otherwise some small statements get just put inside if/then instruction
2015-03-13T13:32:30 < zyp> what about asm volatile("");?
2015-03-13T13:33:56 < zyp> if you want a breakpointable line, you probably want some sort of barrier wrt. instruction reordering, and a volatile asm statement is pretty much the only thing that'll guarantee that

2015-03-13T13:47:38 < zyp> not directly, I think
2015-03-13T13:48:06 < zyp> but you could always grab the handler number from ipsr and then go look up the priority of that handler in the nvic regs
2015-03-13T13:48:22 < jpa-> yeah, and special-case for hardfault etc.
2015-03-13T13:49:58 < zyp> is ipsr is 0, you could argue that current priority is basepri
2015-03-13T13:53:45 < jpa-> hmm, now that i think about this i only care if i'm inside a fault handler (with constant high priority), which is easy to check

2015-03-13T15:56:17 < dongs> even if its not ADC pin?
2015-03-13T15:56:36 < zyp> adc is always connected on ADC pin
2015-03-13T15:56:41 < Tekkkz> Im using the stm32f4disco and want to know what the default frequ. is, cause at the code there is hse value, and other clock values, which is for what?
2015-03-13T15:56:44 < zyp> analog mode otherwise means pin is disconnected
2015-03-13T15:56:50 < xata> dongs: thanks.
2015-03-13T15:56:56 < zyp> so it's not related to mode
2015-03-13T15:57:16 < dongs> zyp, thats what i thought, that its just not connected anywhere.
2015-03-13T15:57:27 < zyp> there's exceptions though, I think oscillator pins are FT except when in oscillator mode
2015-03-13T15:57:28 < dongs> and i guess none of ADC pins are 5V tolerant anyway
2015-03-13T15:57:33 < xata> Tekkkz: try st's _conf generator?
2015-03-13T15:57:33 < zyp> yeah
2015-03-13T15:58:07 < Tekkkz> nono, there is HSE,SYSCLK,HCLK, what is for what? i have already a _conf

2015-03-13T15:58:54 < jpa-> yeah, i was wrong
2015-03-13T15:59:12 < Tekkkz> I just want to know which is for what?
2015-03-13T15:59:46 < dongs> Tekkkz: hse = crystal sysclk = what you are running at , hclk = i duno i think one of bus clocks or someshit. this is in the manual.
2015-03-13T16:00:02 < Tekkkz> oh thanks
2015-03-13T16:00:04 < Tekkkz> sry
2015-03-13T16:00:12 < jpa-> hmm i was wrong for F1 but correct for F4
2015-03-13T16:00:24 < jpa-> on F4, ADC pins at marked 5V tolerant with footnote
2015-03-13T16:00:27 < jpa-> "FT = 5 V tolerant except when in analog mode"
2015-03-13T16:00:33 < dongs> ha
2015-03-13T16:00:43 < dongs> yes, but analog mode means = ADC

2015-03-13T16:01:07 < dongs> wat.
2015-03-13T16:01:07 < jpa-> yes, but the ADC pins are 5V tolerant when not in analog mode
2015-03-13T16:01:42 < jpa-> and also, i think you can put digital pins to analog mode if you want to reduce power consumption for stupid middle-way voltages
2015-03-13T16:01:59 < xata> Tekkkz: c++ on uC's, oh gosh
2015-03-13T16:03:46 < xata> On the other hand i've seen pascal for AVR it is even more oh gosh per tick
2015-03-13T16:03:52 < jpa-> bah, losing 115200bps USART data (IRQ mode) when CPU runs at 8 MHz.. even though the interrupt takes less than 100 cycles so should be plenty of time
2015-03-13T16:03:55 < zyp> jpa-, I thought ADC was always connected
2015-03-13T16:04:04 < zyp> I think on F3 it is
2015-03-13T16:05:20 < zyp> xata, what's wrong with c++ on a mcu?
2015-03-13T16:05:22 < jpa-> zyp: it shows so on F4 also, but it also says what i pasted
2015-03-13T16:05:45 < zyp> huh, weird
2015-03-13T16:06:23 < dongs> hm so wtf

2015-03-13T16:07:17 < dongs> hmm
2015-03-13T16:07:20 < jpa-> zyp: the ref man figure 25 "Basic structure of a five-volt tolerant I/O port bit" also has this strange arrow "Analog" in the right hand side

2015-03-13T16:07:57 < jpa-> xata: since when did c++ use garbage collection?
2015-03-13T16:07:57 < zyp> c++ is not garbage collected

2015-03-13T16:11:26 < zyp> c++ code tends to consume around the same amount of resources as a similar c implementation does
2015-03-13T16:11:49 < zyp> it's just that it takes fewer lines of source to get to that point, so the resource consumption per source line is higher :p
2015-03-13T16:12:05 < dongs> fuck, not this discussion again
2015-03-13T16:12:35 < Tekkkz> no

2015-03-13T16:13:47 < Tekkkz> how is the frequency calculated?
2015-03-13T16:13:48 < dongs> whoa
2015-03-13T16:13:55 < akaWolf> dongs: how I understand you ;)
2015-03-13T16:13:55 < dongs> that almost looks like zypcode
2015-03-13T16:14:12 < zyp> dongs, not enough numbers
2015-03-13T16:14:17 < zyp> also _BV()
2015-03-13T16:14:24 < dongs> ya that looks like tarduino carryover
2015-03-13T16:14:37 < Tekkkz> im suing _BV cause im comming from avr
2015-03-13T16:15:12 < akaWolf> #define _BV(bit) (1 << (bit))
2015-03-13T16:15:27 < zyp> Tekkkz, what do you mean calculated? you're not calculating anything
2015-03-13T16:15:46 < Tekkkz> i mean how can i calculate the frequency the pin is toggled from the timer
2015-03-13T16:16:13 < zyp> timer clock / ARR
2015-03-13T16:16:47 < Tekkkz> whats the tiemr clock? my 168000000Hz?
2015-03-13T16:16:50 < zyp> timer clock is usually equal to SYSCLK, and if you're not changing SYSCLK after boot, you'll be running at 8 MHz
2015-03-13T16:17:15 < Tekkkz> hse is 8
2015-03-13T16:17:15 < zyp> so that pin will be toggling every 21 seconds or so
2015-03-13T16:17:19 < Tekkkz> but not sysclk
2015-03-13T16:17:30 < Tekkkz> and its toggleed faster
2015-03-13T16:17:32 < zyp> where did you enable HSE?
2015-03-13T16:17:44 < Tekkkz> maybe in the _conf?
2015-03-13T16:17:52 < Tekkkz> but im not sure, im new
2015-03-13T16:17:55 < zyp> oh, sorry, 2.1 seconds, I counted a 0 too much
2015-03-13T16:18:16 < Tekkkz> nope, its faster

2015-03-13T16:32:14 < akaWolf> and also multiply
2015-03-13T16:32:20 < akaWolf> not only divide
2015-03-13T16:32:28 < dongs> divide and conquer
2015-03-13T16:32:41 < dongs> damnit you assholes are preventing me from routing this board

2015-03-13T16:33:40 < xata> akaWolf: i imagine it on diagram, so for me it is imagined as division

2015-03-13T16:34:13 < xata> no shit sherlock
2015-03-13T16:34:20 < Tekkkz> so it should toggle with a frequ. of 8.4
2015-03-13T16:34:30 < Tekkkz> => 4 times blinking in 1 sec
2015-03-13T16:34:37 < Tekkkz> but it is only blinking 2 times

2015-03-13T16:42:42 < zyp> if busclock is divided, timers tend to run at twice the busclock
2015-03-13T16:43:20 < gxti_> Tekkkz: so are you toggling the LED each time the timer triggers?

2015-03-13T16:57:43 < xata> well in ukraine stm32 of entry level is cheaper than mega32
2015-03-13T16:58:30 < jpa-> i think you are underestimating the importance of software support
2015-03-13T16:59:05 < jpa-> no-one would use stm32 if the compilers were as crappy as, say, pic; similarly, the libraries are pretty difficult and crappy for a beginner compared to avr
2015-03-13T16:59:29 < Tekkkz> thats right
2015-03-13T16:59:39 < Tekkkz> but with the datasheet its not so difficult
2015-03-13T17:00:07 < jpa-> yes, datasheet + reference manual + raw register access is perfectly reasonable, but it is still over 1000 pages of documentation *just to get started*

2015-03-13T17:00:59 < xata> jpa-: b~ but doing things faster is nice. i mean what is the problem of doing some i2c driver for rare stuff if everything in the end will work times faster?
2015-03-13T17:01:31 < jpa-> xata: speed is not a limiting factor for many things
2015-03-13T17:01:36 < zyp> barrier to entry
2015-03-13T17:01:50 < zyp> and there's no point in arguing with us really, none of us are using avr
2015-03-13T17:01:57 < Tekkkz> is the code downward compatible from f4 to f.e. f1?
2015-03-13T17:02:01 < jpa-> xata: most of my STM32 projects would run just fine on AVR also, i used STM32 because i had already learned it
2015-03-13T17:02:06 < zyp> (none of us would admit it, at least)
2015-03-13T17:02:22 < zyp> Tekkkz, depends
2015-03-13T17:02:27 < jpa-> Tekkkz: not directly; for some peripherals the changes are small, for others they are very large
2015-03-13T17:02:48 < zyp> there are multiple variations and generations of peripherals
2015-03-13T17:03:05 < zyp> some peripherals are the same in all families, some have major differences
2015-03-13T17:03:24 < Tekkkz> okay
2015-03-13T17:03:30 < jpa-> there are two approaches: 1) predict that you want to run on multiple CPUs, separate everything to a HAL layer  or 2) predict that one CPU is enough, and spend some time porting it if that turns out to be false
2015-03-13T17:03:58 < Tekkkz> i'll have a look at this stuff a little deeper and will then decide where im going on
2015-03-13T17:04:01 < jpa-> chibios etc. also have their premade HAL layer, but it is often so low level that some porting effort is still needed

2015-03-13T17:04:32 < dongs> and take your troll pal xata with you
2015-03-13T17:04:35 < xata> jpa-: speed is the main thing anywhere - be it digital lock or drone. time is money and life. the faster your thing does stuff the better it is. on the other hand zyp is right, avr is still a best entry level, but carrying this stuff with you for too long is not a good idea
2015-03-13T17:05:18 < zyp> xata, it doesn't have to be fast, just fast enough
2015-03-13T17:06:16 < jpa-> xata: my wakeup light updates led pwm every 1 ms; 10 ms would be fast enough, what would be the point to make it faster, say 100 or 10 us?

2015-03-13T17:08:32 < zyp> why should I care whether a report takes me two, ten or hundred microseconds to construct? I still have to wait until the next slot before I can do another
2015-03-13T17:09:21 < dongs> is microsecond smaller than millisecond? <this is a serious question>
2015-03-13T17:09:31 < qyx_> yes, sir
2015-03-13T17:09:35 < zyp> there's thousand microseconds in a millisecond

2015-03-13T17:15:46 < jpa-> speed of development is a pretty complex thing; the extra cpu speed on stm32 can ease development a lot

2015-03-13T19:13:51 < jpa-> karlp: no-one launches python here, it is used as a library

2015-03-13T19:15:24 < jadew> but I bet he didn't feel a rush of warm fuzzy feelings when he read the news
2015-03-13T19:15:55 < jadew> I received my hackrf yesterday, it's not that great
2015-03-13T19:16:27 < emeb> HackRF is not that great? What's wrong?
2015-03-13T19:16:28 < _Sync_> I'm always pissed of at the low large signal rejection of all the SDRs
2015-03-13T19:16:34 < jadew> for one, a $14 rtlsdr dongle appears to be more sensitive
2015-03-13T19:16:56 < emeb> Interesting
2015-03-13T19:17:12 < jadew> then there are lots of images and I think it's receiving a some internal noise every 20 MHz or something like that
2015-03-13T19:17:30 < emeb> rtlsdr dongles have a lot of birdies too
2015-03-13T19:17:32 < jadew> so you end up with a big spike in the spectrum
2015-03-13T19:17:38 < jadew> emeb, not like this
2015-03-13T19:17:49 < emeb> jadew: ouch!
2015-03-13T19:17:58 < emeb> worse than rtlsdr doesn't speak well.
2015-03-13T19:18:22 < jadew> yeah, I couldn't believe it when I noticed I can't find some stations I knew were there
2015-03-13T19:18:32 < emeb> I get the feeling that a lot of the SDR hardware out there is being designed by folks who don't know much about radio design.
2015-03-13T19:18:39 < jadew> I plugged in the RTLSDR - same antenna - bam, I could listen to them
2015-03-13T19:19:08 < jadew> emeb, yeah, it sure looks like it, I don't know how he manage to get all that noise in
2015-03-13T19:19:08 < _Sync_> strange
2015-03-13T19:19:12 < dongs> god damn
2015-03-13T19:19:12 < _Sync_> must be really really deaf then
2015-03-13T19:19:13 < jpa-> maybe the antenna is better matched to RTLSDR than to the hackrf?
2015-03-13T19:19:17 < dongs> how can i filter out wind noise in mic
2015-03-13T19:19:22 < dongs> does it have some common shit
2015-03-13T19:19:23 < _Sync_> because the rtlsdr is shit insenitive too
2015-03-13T19:19:31 < dongs> i got some recording and its completely wrothless
2015-03-13T19:19:38 < jadew> jpa-, 50 ohm coax to both of them
2015-03-13T19:19:41 < emeb> I remember looking at the HackRF circuit and not being real impressed.
2015-03-13T19:19:43 < zyp> dongs, dead cat
2015-03-13T19:19:48 < dongs> zyp, wat
2015-03-13T19:19:50 < jadew> so if anything, the hackrf is not matched to 50 ohm properly
2015-03-13T19:19:57 < emeb> Microphone Merkin!
2015-03-13T19:20:01 < dongs> zyp, post-processing :)
2015-03-13T19:20:04 < jpa-> or neither your antenna nor the rtlsdr is matched to 50 ohm?
2015-03-13T19:20:21 < _Sync_> isn't the rtlsdr shit 75ohm?
2015-03-13T19:20:30 < jadew> _Sync_, it could be
2015-03-13T19:20:36 < zyp> dongs, oh, right
2015-03-13T19:20:37 < jadew> actually, you're probably right
2015-03-13T19:20:43 < jadew> it's meant to work with cable tv
2015-03-13T19:20:46 < zyp> better to not pick it up in the first place :p
2015-03-13T19:20:50 < _Sync_> 75 ohm then
2015-03-13T19:20:53 < jadew> yeah
2015-03-13T19:20:57 < jpa-> some "rtlsdr" sticks are just planned to have a wire sticking right out of the antenna port, so maybe some >100 ohms?
2015-03-13T19:21:05 < jpa-> ah, cable versio 
2015-03-13T19:21:31 < jadew> jpa-, yeah, meaning that the rtlsdr even had a disadvantage here
2015-03-13T19:21:48 < jpa-> is your antenna properly matched to 50 ohms then?
2015-03-13T19:21:59 < jadew> jpa-, doesn't matter, same antenna, same cable
2015-03-13T19:22:15 < jadew> all the reflection that is going to happen because of that mismatch is going to end where the antenna meets the cable
2015-03-13T19:22:17 < emeb> 50 ohm / 75 ohm mismatch doesn't make that much difference in power transfer.
2015-03-13T19:22:32 < jpa-> jadew: uh, no
2015-03-13T19:22:33 < jadew> from there on it's the cable match to the receiver
2015-03-13T19:23:07 < jpa-> unless your cable is very long compared to the wavelength
2015-03-13T19:23:09 < emeb> only about 0.35dB loss
2015-03-13T19:23:13 < jadew> jpa-, it is
2015-03-13T19:23:17 < jpa-> ok
2015-03-13T19:23:36 < jadew> good cable tho

2015-03-13T19:33:00 < jadew> 130/137
2015-03-13T19:33:33 < jadew> so, I made a test earlier with the hackrf and I mentioned this: "I can hear a signal down to 128 dBm, see it down -132 dBm (barely)"
2015-03-13T19:33:54 < jadew> with rtlsdr I can hear it down to 130
2015-03-13T19:33:59 < jadew> and see it down to 137
2015-03-13T19:34:20 < emeb> not a huge difference
2015-03-13T19:34:44 < jadew> emeb, seems to be enough that some stations are not visible with the hackrf
2015-03-13T19:34:54 < jadew> also, this is at 120 MHz
2015-03-13T19:35:01 < emeb> Aircraft?
2015-03-13T19:35:02 < jadew> those stations were at 200 something
2015-03-13T19:35:16 < jadew> no, the signal is comming from my sig gen
2015-03-13T19:35:19 < emeb> ah
2015-03-13T19:35:24 < jadew> and I'm attenuating it

2015-03-13T19:35:54 < jadew> arbitrary
2015-03-13T19:35:55 < jadew> 120 MHz
2015-03-13T19:39:45 < jadew> I can hear down to -132 dBm, had the volume down
2015-03-13T19:40:10 < emeb> what modulation?
2015-03-13T19:40:33 < jadew> FM 400 Hz signal with 2 kHz deviation
2015-03-13T19:40:55 < emeb> so your hear vs see delta is 4-5dB in both cases
2015-03-13T19:41:22 < jadew> yeah
2015-03-13T19:44:45 < emeb> IIRC HackRF is a fairly big board compared to RTLSDR dongles?
2015-03-13T19:44:53 < jadew> yeah
2015-03-13T19:44:59 < emeb> what kind of shielding / enclosure does it have?

2015-03-13T19:45:16 < jadew> it has a footprint for a shield, but it's not populated
2015-03-13T19:45:21 < emeb> interesting
2015-03-13T19:45:32 < jadew> I wonder if that would keep the interference out or if it's just an issue of bad return path
2015-03-13T19:46:53 < jadew> I'm a bit bummed about this tbh
2015-03-13T19:46:59 < dongs> this is why you buy pro tools
2015-03-13T19:47:00 < emeb> understood
2015-03-13T19:47:11 < emeb> jadew: wonder how it compares to a USRP
2015-03-13T19:47:19 < ReadError> freq rang on the rtl stuff sucks

2015-03-13T19:48:09 < emeb> USRP has been around a while, but you need to buy different front-end daughter-cards for it.
2015-03-13T19:48:20 < emeb> so the cost can be steep to cover the same range.
2015-03-13T19:48:36 < jadew> yeah, it's above my budget
2015-03-13T19:48:39 < ReadError> USRP has higher bandwidth and full duplex
2015-03-13T19:48:48 < ReadError> but i duno how to SDR yet
2015-03-13T19:49:02 < emeb> They've got a newer one with a super-fancy ADI converter chip that has wider range than the original ones.
2015-03-13T19:49:04 < ReadError> so figured the hackrf will get me somethin i can dick around with
2015-03-13T19:50:21 < jadew> ReadError, you can deffinitely dick around with it, but for $300 or more (depending on where you are) you kinda expect better sensitivity than the rtlsdr
2015-03-13T19:51:09 < ReadError> jadew, for me it was wanting to do stuff above 1.7
2015-03-13T19:51:18 < ReadError> simple noise floor stuff in the field
2015-03-13T19:51:35 < dongs> https://ksr-ugc.imgix.net/assets/003/433/660/bc432328b6c0a5e1b9075abbd1da32a4_original.jpg?v=1426255831&w=700&h=&fit=max&auto=format&q=92&s=9a40ed0f8b30b486662bcc2a7b7d113b
2015-03-13T19:51:39 < emeb> I wonder how HackRF performs when you get into the range where it's front-end chip is actually specified.
2015-03-13T19:51:51 < emeb> IIRC they use a chip that's not rated to go < 300MHz
2015-03-13T19:51:57 < emeb> It just happens to work there.
2015-03-13T19:52:07 < ReadError> i guess its 2.1-2.7Ghz
2015-03-13T19:52:13 < ReadError> on the frontend
2015-03-13T19:52:39 < emeb> Looks like internally there is a shield on the PCB
2015-03-13T19:53:39 < ReadError> emeb, he mentioned being able to go sub 1Mhz
2015-03-13T19:53:44 < ReadError> and getting valid data
2015-03-13T19:53:55 < ReadError> on RFID stuff
2015-03-13T19:54:05 < jadew> ReadError, I tried it down to 2 MHz
2015-03-13T19:54:12 < emeb> ReadError: no doubt. Just wonder how much the performance suffers...
2015-03-13T19:54:30 < jadew> I was able to see a -90 dBm signal
2015-03-13T19:54:39 < jadew> at 2 MHz
2015-03-13T19:54:45 < ReadError> thats not too bad
2015-03-13T19:54:56 < jadew> it's not great either
2015-03-13T19:55:10 < jadew> but it works
2015-03-13T19:55:13 < ReadError> what do you get within the low end of the spec? 10?
2015-03-13T19:55:25 < jadew> at 10 MHz, -110 dBm
2015-03-13T19:56:13 < jadew> btw, these are signals that I can barely see
2015-03-13T19:56:53 < karlp> what's at 10Mhz anyway? rfid is what, 125k or 12mhz, but what else is that low?

2015-03-13T19:58:56 < jadew> I'd try it at 1 GHz or so too, but then the RTLSDR would be at it's limit

2015-03-13T20:09:54 < jadew> mine's sensitivity is pretty much garbage at 1.1 GHz

2015-03-13T20:16:11 < jadew> karlp, that's good to know, but I just realized that it picks up the 1 GHz signal with out the whole attenuator assembly being connected to the thing that's generating it

2015-03-14T01:06:12 < stephendwyer> Hi all, any thoughts on the following? When using a bootloader, one must assign the application vector table address to SCB_VTOR. Is it more correct to assign the address right in flash, for example: 0x08002000 or is it better to do it to the aliased location, for example, 0x00002000?

2015-03-14T02:03:30 < Laurenceb_> oh
2015-03-14T02:03:37 < Laurenceb_> yeah i looked at the text, that was it
2015-03-14T02:03:41 < dymk> the datasheet says for the 100 pin package, but not for the 64 pin one lol
2015-03-14T02:03:42 < Laurenceb_> gave up on the dots
2015-03-14T02:03:55 < Laurenceb_> the datasheet shows the text orientation
2015-03-14T02:04:13 < dymk> huh
2015-03-14T02:04:23 < qyx_> yes, when you can read the text, the right one should be on the left bottom
2015-03-14T02:05:16 < dymk> pin 1 is left bottom of the text?

2015-03-14T03:37:29 < Getty> seeing the first comment, i should actually check if i still have this HD-maker ......
2015-03-14T03:38:34 < dongs> whoa i bought this jap software, it comes on cdrom
2015-03-14T03:38:49 < zyp> wow, modern
2015-03-14T03:39:00 < dongs> haha the CD is 90megs
2015-03-14T03:48:56 < dymk> qyx_, yay, openocd now talks to the chip now
2015-03-14T03:49:05 < dymk> was indeed in need of a 180 rotation
2015-03-14T03:49:20 < qyx_> i am surprised you didn't fry it
2015-03-14T03:50:12 < dymk> so am i
2015-03-14T03:50:36 < dymk> hey maybe i did fry it, haven't tested all periphreals yet
2015-03-14T03:50:49 < dymk> but flash erases, and stlink and openocd talk to it seemingly fine
2015-03-14T03:51:12 < dymk> is there some place i can find the mapping of reported chip ID to stm32f4 model?
2015-03-14T03:51:42 < qyx_> maybe the datasheet
2015-03-14T03:52:34 < qyx_> i don't know if theres any table listing all models
2015-03-14T03:53:22 < upgrdman> starting my official EE Pro Troll training today. "start by reading this copy of IEC 60601" ... FML
2015-03-14T03:54:30 < dymk> hm, stlink is reporting "Flash: 0 bytes (0 KiB) in pages of 16384 bytes"
2015-03-14T03:54:32 < upgrdman> on the plus side, there's a neat looking xray tube/HV PSU sitting on my desk
2015-03-14T03:54:33 < dymk> perhaps i did fry it

2015-03-14T04:37:27 < ds2> switches as in relays?
2015-03-14T04:37:56 < emeb_mac> monolithic switches - skyworks stuff
2015-03-14T04:38:17 < ds2> aren't they just MOSFETs?
2015-03-14T04:38:26 < BrainDamage> relays become rather complex at GHz, tyically they are diode bridges
2015-03-14T04:39:06 < emeb_mac> well RF switches do *use* GaAsFETs
2015-03-14T04:39:15 < emeb_mac> but there's a bit more to them to get goo matching, etc.
2015-03-14T04:40:07 < upgrdman> gaasfet's have faster rise/fall times than mosfets?
2015-03-14T04:40:43 < emeb_mac> GaAs is just better for GHz RF
2015-03-14T04:40:57 < upgrdman> ok
2015-03-14T04:41:11 < upgrdman> what datasheet line(s) would that be?
2015-03-14T04:41:14 < emeb_mac> HackRF is supposed to be good up to 6GHz
2015-03-14T04:41:17 < ds2> being active devices, don't they add more noise then their ohm resistance would?
2015-03-14T04:41:21 < upgrdman> i mean, what charactics are better or worse
2015-03-14T04:41:37 < emeb_mac> ds2: they're not amplifying - just set up as pass transistors
2015-03-14T04:42:28 < ds2> thought all transistors regardless of their mode adds noise?
2015-03-14T04:43:31 < emeb_mac> that's not my understanding
2015-03-14T04:43:40 < emeb_mac> but these are a bit lossy - 0.5dB
2015-03-14T04:43:48 < emeb_mac> so there's that
2015-03-14T04:44:18 < emeb_mac> upgrdman: look up these parts: SKY13350

2015-03-14T04:45:07 < dongs> japanese software on cdrom used internet license check
2015-03-14T04:45:16 < dongs> .. by calling a named export in lol.dll
2015-03-14T04:45:23 < dongs> which returned a number on success/fail.
2015-03-14T04:45:46 < dongs> i mean i paid for the shit but why would I want to connect to internet for that kinda crap
2015-03-14T04:46:08 < dongs> so I just made a .dll with int CheckAuthTB(void) { return 5; } and it worked.

2015-03-14T07:07:50 < dymk> the datasheet doesn't mention it
2015-03-14T07:12:28 < dongs> how about schematic

2015-03-14T07:25:03 < zyp> probably won't work, wonder if I have diodes somewhere
2015-03-14T07:34:31 < emeb_mac> diodes, cap, lm1117 - should work
2015-03-14T07:37:53 < zyp> that's what I just ghettoed together
2015-03-14T07:38:33 < emeb_mac> depends on how much current you need though - a lot of serial ports use something like MAX232 that's only rated to source about 2ma
2015-03-14T07:39:03 < emeb_mac> 10ma short-circuit, but that won't likely get your regulator biased...

2015-03-14T09:47:25 < dymk> that handsoldering job was a bitch though
2015-03-14T09:47:33 < PaulFertser> dymk: do you mean you really implemented a microcontroller logic? Or a microcontroller-based board?
2015-03-14T09:47:40 < dymk> no just the board
2015-03-14T09:47:47 < PaulFertser> :)
2015-03-14T09:47:54 < dymk> which isn't that hard, given; just need a few caps and some buttons ;)
2015-03-14T09:47:59 < PaulFertser> It's just that sometimes people do implement CPU cores on FPGA.
2015-03-14T09:48:12 < dymk> i'll be doing that in a class next quarter!

2015-03-14T09:51:31 < PaulFertser> dymk: exactly
2015-03-14T09:51:35 < PaulFertser> dymk: or just "mon"
2015-03-14T09:51:40 < dymk> ah nice
2015-03-14T09:52:09 < PaulFertser> dymk: and use extended-remote, not remote when connecting, then you'll be able to "start" and "run" (both perform target reset).
2015-03-14T09:52:21 < dymk> I'll add that to the .gdbinit
2015-03-14T09:53:41 < dymk> i found this great shop on campus that did the 3d printing for the bot at a great rate

2015-03-14T10:05:36 < dongs> open them sores
2015-03-14T10:16:28 < PaulFertser> dymk: btw, I see your board lacks SWO, you'll probably want tracing functionality it enables in the next project.
2015-03-14T10:18:24 < dymk> PaulFertser, is that the 6th pin of the SWD connector, "Reserved", on the stm32f4discover board?
2015-03-14T10:19:21 < PaulFertser> dymk: yes, but why "reserved"? I thought it's SWO input on all stlinkv2 and stlinkv2-1 boards.
2015-03-14T10:19:38 < dymk> That's just what it calls that pin in the datasheet
2015-03-14T10:19:52 < dymk> the discovery board datasheet
2015-03-14T10:22:12 < dymk> At any rate, I did try to reserve that pin, but it couldn't be used as it's one of the encoder channel ins for TIM2
2015-03-14T10:22:45 < dymk> TIM2 had to be used as it's one of the 32 bit timers
2015-03-14T10:23:05 < dongs> doesnt TIM2 have pins all over the place
2015-03-14T10:23:30 < dymk> which conflict with pins on TIM5

2015-03-14T13:14:01 < jpa-> yeah, back in 2000 i tried to program one using parallel port on my 386
2015-03-14T13:14:03 < jpa-> didn't work
2015-03-14T13:14:19 < Tekkkz> parallel is difficult i think
2015-03-14T13:14:23 < Tekkkz> but other question:
2015-03-14T13:14:46 < xata> jpa-: it is ok on gromov programmer
2015-03-14T13:14:58 < Tekkkz> at avr, i have basically my main.c nad maybe a main.h and an other file, f.e. spi lib (but not necessary) thats it.
2015-03-14T13:15:01 < jpa-> xata: got a time machine so that you can send me one?
2015-03-14T13:15:03 < xata> but it needs a simple circuit
2015-03-14T13:15:16 < Tekkkz> BUT!!
2015-03-14T13:15:48 < Tekkkz> how is it with stm32: i have main.c; startup.s system.c lib/CMIS lib/STM32xx
2015-03-14T13:15:48 < baird> Won't be betting an ST tattoo then.
2015-03-14T13:16:31 < Tekkkz> so: main.c ofc, lib/STM32xx ofc, but for what is CMIS, what is it?
2015-03-14T13:16:36 < ReadError> Tekkkz is this going somewhere?
2015-03-14T13:16:58 < Tekkkz> i just want to compare the file structures

2015-03-14T13:17:10 < ReadError> you can put the files anywhere you want
2015-03-14T13:17:18 < xata> Tekkkz: it helps writing your code without register bytesex
2015-03-14T13:17:19 < jpa-> i don't have such folders in my projects
2015-03-14T13:17:35 < Tekkkz> YOU DONT HAVE? WHAT DO YOU HAVE?
2015-03-14T13:17:39 < Tekkkz> sry for caps
2015-03-14T13:18:05 < karlp> you have startup for avr too, you just don't see it...
2015-03-14T13:18:06 < jpa-> just core_cm3.h (registers for cortex-m3 cpu core), stm32f1xx.h (registers for stm32 peripherals), stm32.ld (position of code in memory), main.c, startup.c (no need to use assembler for startup)
2015-03-14T13:18:09 < Tekkkz> i just downloaded a code template with all this stuff
2015-03-14T13:18:36 < Tekkkz> can you upload please your project template? im interest in its simplicity
2015-03-14T13:18:37 < xata> jpa-: you don't use spl? why?
2015-03-14T13:18:50 < jpa-> xata: stdperiph is just a bunch of useless wrappers
2015-03-14T13:18:57 < Tekkkz> +1 for jpa-
2015-03-14T13:18:57 < jpa-> i don't need them
2015-03-14T13:19:04 < Tekkkz> at avr you dont have such things
2015-03-14T13:19:29 < Tekkkz> jpa-: can you please make a basic blink programm with timer and send me your project so i can check it out pls
2015-03-14T13:19:31 < jpa-> Tekkkz: well if you want a minimal one, maybe this?  https://github.com/PetteriAimonen/STM32_Trace_Example   (the few extra .h's are dependencies of the core_cm3.h)
2015-03-14T13:19:53 < xata> jpa-: so you are of register bangers. It is a cause of taste
2015-03-14T13:20:11 < jpa-> xata: i use chibios quite often also, it has more useful drivers
2015-03-14T13:20:25 < jpa-> i can't see any benefit in stdperiph
2015-03-14T13:20:33 < Tekkkz> but is the stm32f4disco not an m4 cortex?
2015-03-14T13:20:48 < jpa-> Tekkkz: yeah, i would assume you have core_cm4.h there somewhere
2015-03-14T13:21:16 < Tekkkz> not at the example template, can you please make one for me? im eating now, please :D
2015-03-14T13:21:21 < jpa-> no

2015-03-14T13:25:11 < karlp> well, the sun just came out,
2015-03-14T13:25:17 < karlp> but it was 50m/sec gusts this morning.
2015-03-14T13:25:28 < karlp> windiest I remember in town
2015-03-14T13:25:43 < jpa-> huh
2015-03-14T13:25:53 < karlp> lots of light, but it's been kinda non-stop train wreck of storms every second day for a few months now :)
2015-03-14T13:25:58 < jpa-> nice and sunny here but below 0 most of the day
2015-03-14T13:26:07 < karlp> it was 7C this morning
2015-03-14T13:26:17 < karlp> causing flooding of course, melting snow too fast
2015-03-14T13:26:30 < qyx_> huh
2015-03-14T13:26:44 < qyx_> no show here, 7C too, rain :S
2015-03-14T13:26:45 < karlp> apparentlty the road was being ripped up by the wind south of here.
2015-03-14T13:27:05 < karlp> I was quite impressed the neighbours tree didn't get ripped out, there's a few others around town ripped up
2015-03-14T13:27:56 < karlp> it's very much don't go outside unless you relallllly need to weather
2015-03-14T13:28:10 < karlp> meant to ease up this afternoon, then comes the rain apparently.
2015-03-14T13:28:38 < qyx_> last time when we had 180km/h in 2004, half of a national park was blown away

2015-03-14T16:44:41 < Tectu> Tekkkz, I'd recommednt to open the corresponding header and ctrl+f for the struct and you'll probably find what you need
2015-03-14T16:44:44 < Tectu> Tekkkz, or google
2015-03-14T16:45:02 < Tekkkz> nono

2015-03-14T16:47:35 < Tekkkz> yes he is
2015-03-14T16:47:42 < Tekkkz> he doesnt answer me ;(
2015-03-14T16:47:48 < Tekkkz> rkreis: it isnt the clock
2015-03-14T16:48:06 < rkreis> i don't use CMSIS either (libopencm3 instead)
2015-03-14T16:48:06 < Tectu> Tekkkz, then you are screwed anyway. as soon as even jpa- gave up on you you know that you're done :)

2015-03-14T17:10:57 < rkreis> and not the topic either
2015-03-14T17:11:01 < Getty> well in compare, yes, but its not something that people should take too serious
2015-03-14T17:11:46 < Getty> if you take all the unixes, then linux is by far one of the worst, but its just because its different, its modern, it "tries" things, it is made for usability, not performance/security (see BSD), thats all ok
2015-03-14T17:11:58 < Getty> but that also means that you have to take bad comments about it sometimes of the BSD guys ;) and they are right ;)

2015-03-14T17:21:34 < Tectu> Tekkkz, two reasons why people don't help on IRC:   1.)  They actually don't know or they don't have time/motivation   2.) because you're annoying
2015-03-14T17:21:39 < Tectu> in 99% of the cases 2.) is the case
2015-03-14T17:22:01 < Tekkkz> here are 8 guys active and 4 of them are telling me shit
2015-03-14T17:22:10 < Tectu> sure.

2015-03-14T17:27:41 < Getty> ;)
2015-03-14T17:28:02 < Getty> start with looking at other peoples code and learn how to make it more, actually you should really think about using some lib
2015-03-14T17:28:31 < Tekkkz> I created a simple minimalistic project for stm32f4 with following files: core_cm4.h core_cm4_simd.h core_cmFunc.h core_cmInstr.h stm32f4xx.h system_stm32f4xx.h main.c => I'm compiling it and the leds dont turn on, the main.c is correct, if you wanna help i can show you my makefile ..
2015-03-14T17:28:42 < Tekkkz> but i wont use the stdperiphlib
2015-03-14T17:28:46 < Tekkkz> cause i dont need it actually
2015-03-14T17:28:48 < Tekkkz> AND
2015-03-14T17:29:23 < Tekkkz> please help me.. i have no rl friends, no computerfriends and the irc is unfriendly aswell, pleae be friendly or im crying ... now im waiting ..
2015-03-14T17:30:22 < dongs> Tekkkz: keil is free  for up to 32k

2015-03-14T17:31:51 < Tekkkz> and you know what i need for it
2015-03-14T17:31:55 < Tekkkz> why arent you telling me
2015-03-14T17:31:59 < Tekkkz> i googled much

2015-03-14T17:32:26 < dongs> so ill just go to sleep instead
2015-03-14T17:32:45 < _Sync_> just look at libopencm3 and work your way down

2015-03-14T18:33:42 < jpa-> i don't understand what you mean

2015-03-14T18:35:59 < jpa-> when i do, there usually is either pin header that i can just connect to with wires, or then i solder small wires to the board

2015-03-14T18:42:18 < jpa-> soldered wires? they look crimped to me
2015-03-14T18:42:38 < jpa-> what do you need jtag for?

2015-03-14T18:43:21 < jpa-> umm
2015-03-14T18:43:57 < jpa-> why not just buy a bunch of   http://www.ebay.com/itm/40PCS-2-54MM-Dupont-Wire-Cable-Female-to-Female-Male-to-Female-Male-to-Male-/271579357837?pt=LH_DefaultDomain_0&var=&hash=item3f3b64228d   and connect directly from the j-link pin header?
2015-03-14T18:44:41 < jpa-> print / draw a label and glue it to the jlink so you remember the pinout
2015-03-14T18:45:05 < jpa-> and use SWD whenever the chip supports it, so you only need 3 wires and no labels
2015-03-14T18:45:30 < qyx_> i use exactly those 20cm dupont wires
2015-03-14T18:45:36 < qyx_> one end goes to stlinkv2
2015-03-14T18:45:41 < qyx_> and the other to my board
2015-03-14T18:45:51 < jpa-> same for me

2015-03-14T20:24:37 < BrainDamage> just masochism
2015-03-14T20:24:45 < Tectu> how about german? I assume there are some mandatory forgein languages?

2015-03-14T20:25:38 < BrainDamage> yep
2015-03-14T20:26:00 < BrainDamage> only english was mandatory, i picked french as part of optional courses

2015-03-14T22:29:58 < dymk> Hm, has anyone had this issue before? I'm using the HAL, and my code keeps getting stuck in WWDG_IRQHandler, but I never configured the WWDG_IRQHandler anywhere
2015-03-14T22:30:35 < dymk> Commenting out the generated SystemClock_Config call doesn't result in WWDG_IRQHandler getting called though
2015-03-14T22:33:20 < Tekkkz> are you suing the watchdog?
2015-03-14T22:33:44 < dymk> Tekkkz, nope
2015-03-14T22:33:59 < Tekkkz> sure it is disabled?
2015-03-14T22:34:51 < dymk> it's not "activated" STM32CubeMX, and I don't see any calls to enable it
2015-03-14T22:34:56 < dymk> How would I check that it's actually disabled?
2015-03-14T22:35:00 < Steffanx> probably and unhandles exception
2015-03-14T22:35:55 < Steffanx> or a hardfault
2015-03-14T22:37:27 < Tekkkz> im beginner in stm, but at avr if the wd resets there is a "problem"
2015-03-14T22:39:53 < englishman> using avr is a "problem" already
2015-03-14T22:40:03 < Tekkkz> pff why would you say this?
2015-03-14T22:40:41 < _Sync_> Getty: ja ne panemaju
2015-03-14T22:41:22 < Steffanx> most of the time unhandled exceptions end up in the same (default) interrupt handler. And in your case it default handler probably ended up with the symbol WWDG_IRQHandler dymk
2015-03-14T22:41:24 < Getty> je ne parle _PLUS_ de francaise
2015-03-14T22:41:37 < Steffanx> je ne parle pas français.

2015-03-14T23:11:44 < Fleck> ;p
2015-03-14T23:13:32 < dymk> Steffanx, you're right, it's not the WWDG handler firing; when I declare WWDG_IRQHandler in main.c GDB reports it's calling UsageFault_Handler now
2015-03-14T23:13:57 < dymk> i'm guessing GDB is resolving the function address to a name in reverse alphabetical order or smth
2015-03-14T23:14:13 < Fleck> Tectu: no problem, give me your address and I will send it back
2015-03-14T23:15:26 < Tectu> Fleck, totally kidding there.

2015-03-15T00:48:08 < PeterM> that just calculates the ripple current rating of the cap and its max voltage not the value of the cap

2015-03-15T00:53:26 < PeterM> but since the cap couples ALLthe power from input to output, if you only sized the cap to block those frequencies, it would effect how much power you could draw from the output
2015-03-15T00:56:05 < PeterM> yeah i figured that or just build one up and scope it
2015-03-15T00:58:55 < PeterM> the coupled inductords is only to reduce board space/requred inductance because of mutual inductance
2015-03-15T01:00:12 < PeterM> two seperate inductors work just as well
2015-03-15T01:01:59 < PeterM> battery charger for telecoms need -50v out with no/minimal parasitic discharge
2015-03-15T01:07:06 < PeterM> needs some other stuff too, but sepic seemed the best because vin canbe higher or lower than vout

2015-03-15T05:21:36 < dymk> ReadError, it looks like stdperiph uses GPIOJ, but that's not a gpio port on the 405
2015-03-15T05:21:48 < dymk> are there multiple releases of the stdperiph for each family of chips?
2015-03-15T05:24:50 < ReadError> dymk so just dont use GPIOJ
2015-03-15T05:25:05 < dymk> ReadError, the library itself references GPIOJ
2015-03-15T05:25:16 < dymk> not #ifdef'd or anything
2015-03-15T05:25:26 < ReadError> im using it fine w/o any issues..
2015-03-15T05:26:13 < dymk> huh, I downloaded it from here: http://www.st.com/web/en/catalog/tools/PF257901
2015-03-15T05:26:14 < dymk> same one?
2015-03-15T05:27:21 < ReadError> im not sure the issue?
2015-03-15T05:27:28 < ReadError> its the same libs for all the f4
2015-03-15T05:28:12 < dymk> I mean, issue is the libraries won't compile without GPIOJ defined, which doesn't exist on the stm32f405
2015-03-15T05:29:48 < emeb_mac> stdperiph libs do reference GPIO ports that don't exist on some parts
2015-03-15T05:30:09 < emeb_mac> you need to -D define what processor your using in the compile options
2015-03-15T05:30:28 < dymk> emeb_mac, will that define dummy values for those referenced ports or something?
2015-03-15T05:31:04 < emeb_mac> something like that - havent looked in a while
2015-03-15T05:34:16 < dymk> there's no goddamn documentation on this
2015-03-15T05:34:19 < dymk> ugh
2015-03-15T05:34:33 < emeb_mac> use the source luke
2015-03-15T05:35:31 < dymk> of course it doens't come with a stm32f4xx.h
2015-03-15T05:35:36 < ReadError> or use keil

2015-03-15T05:48:14 < emeb_mac> dymk: does your copy of stm32f4xx.h match the StdPeriph your using?
2015-03-15T05:48:33 < emeb_mac> if you've got an old / mismatched version of the main header then you'll see this error
2015-03-15T05:50:21 < dymk> emeb_mac, probably not, because this StdPeriph doesn't come with a stm32f4xx.h
2015-03-15T05:50:49 < emeb_mac> dymk: how did you get your StdPeriph source?
2015-03-15T05:51:03 < dymk> emeb_mac, via this link: http://www.st.com/web/en/catalog/tools/FM147/CL1794/SC961/SS1743/LN1734/PF257901?s_searchtype=keyword
2015-03-15T05:51:37 < dymk> I assume "STM32F4 DSP and standard peripherals library" means StdPeriph? and the folders in that archive are STM32F4xx_StdPeriph_Driver
2015-03-15T05:52:34 < emeb_mac> ya
2015-03-15T05:53:01 < emeb_mac> there's also a Libraries/CMSIS dir - the main header should be in there somewhere
2015-03-15T05:53:23 < dymk> oh! yep!
2015-03-15T05:54:25 < emeb_mac> that one will have GPIOJ defined
2015-03-15T05:55:41 < dymk> so with stdperiph there's no stm32f405xx.h?
2015-03-15T05:55:52 < dymk> just the general f4xx.h
2015-03-15T05:56:03 < emeb_mac> correct

2015-03-15T17:35:48 < Tekkkz> i have a question: for what reason is a crystal at the stm32f4 and all other boards, i thought they have 168MHz, crystal is 8MHz, why is it on the board?
2015-03-15T17:35:58 < dongs> didnt you already ask this

2015-03-15T17:36:05 < Tekkkz> im not sure
2015-03-15T17:36:08 < Tekkkz> i dont htink so
2015-03-15T17:36:11 < dongs> and were told about PLL
2015-03-15T17:36:14 < dongs> or maybe it was someone as dumb as you
2015-03-15T17:36:16 < Tekkkz> wait
2015-03-15T17:36:19 < BrainDamage> it's easier to make crystals at lower freq, and multiply it up in a pll
2015-03-15T17:36:33 < BrainDamage> the crystal acts as stable reference

2015-03-15T17:41:54 < dongs> ST clearly doesnt actually give a fuck about htier customers
2015-03-15T17:41:57 < Tekkkz> so what sshould i google/read at wikipedia about for PLL? whats this called?
2015-03-15T17:41:58 < dongs> and timecube is java
2015-03-15T17:42:04 < dongs> so the only logical way to integrate timecube into ST IDE
2015-03-15T17:42:06 < dongs> is to use eclipse + java
2015-03-15T17:42:08 < Lux> dongs: iirc it's going to be eclipse based

2015-03-15T17:45:51 < dongs> less pins

2015-03-15T21:55:08 < Tekkkz> and for th protocol, checkout usb
2015-03-15T21:55:13 < Tekkkz> ant wikipedia f.e.
2015-03-15T21:55:27 < Tekkkz> i think its more deeper into usb functionality
2015-03-15T21:56:53 < qyx_> i think that tecdroid is expecting something like "this is a protocol for doing foo and bar, you can find more detailed description in a baz's documentation. it should be set to this and that. " etc
2015-03-15T21:57:00 < qyx_> at least there should be no magic numbers

2015-03-15T21:58:14 < Tekkkz> thats what im saying
2015-03-15T21:58:22 < Tekkkz> tecdroid should just copy-paste it

2015-03-15T22:07:21 < Tekkkz> which stm32 chip has the lowest pin count?
2015-03-15T22:09:56 < tecdroid> f103C8T6
2015-03-15T22:10:04 < tecdroid> or cbt6
2015-03-15T22:10:13 < tecdroid> lqfp48
2015-03-15T22:10:23 < Tekkkz> ok thx
2015-03-15T22:10:38 < tecdroid> but does that matter for smt devices?
2015-03-15T22:10:52 < qyx_> not true
2015-03-15T22:11:01 < Tekkkz> no, but for soldering by your owm
2015-03-15T22:11:01 < qyx_> there are 20pin tssop chips
2015-03-15T22:11:07 < Tekkkz> ahh rly?
2015-03-15T22:11:08 < qyx_> also 28pin/32pin qfn
2015-03-15T22:11:35 < qyx_> dongs has even found qfn16 accelerometer with embedded cortex-m0
2015-03-15T22:11:47 < Tekkkz> lol
2015-03-15T22:12:56 < qyx_> see stm32f030f4p6 for example
2015-03-15T22:13:20 < Tekkkz> STM32F042F6 is better :P
2015-03-15T22:14:04 < Tekkkz> oh no
2015-03-15T22:14:09 < qyx_> why?
2015-03-15T22:14:13 < Tekkkz> it has usb
2015-03-15T22:14:19 < qyx_> mhm, ok
2015-03-15T22:14:26 < Tekkkz> its the only reason :D
2015-03-15T22:14:36 < Tekkkz> everything else is worse
2015-03-15T22:14:57 < PaulFertser> lis331eb is 3x3x1 LGA, even smaller
2015-03-15T22:15:16 < qyx_> yep, thats the one with accelerometer
2015-03-15T22:15:29 < Tekkkz> in-chip?
2015-03-15T22:15:35 < Laurenceb_> does that have an stm32?
2015-03-15T22:15:46 < PaulFertser> Cortex-M0 inside
2015-03-15T22:16:01 < Tekkkz> but also no usb ;(
2015-03-15T22:16:17 < ds2> lis331eb has an accessible cortex-m0 in it?
2015-03-15T22:16:29 < Tekkkz> y
2015-03-15T22:16:30 < tecdroid> Tekkkz, but you dont solder pin by pin?
2015-03-15T22:16:36 < ds2> Nice
2015-03-15T22:16:59  * ds2 makes notes
2015-03-15T22:17:04 < Tekkkz> yes, i do, i have 0.01mm solder wire and a solder iron with a 0.1mm ;) no, ofc not
2015-03-15T22:17:23 < ds2> now if I can find a 9 axis chip with a cortex-m0 that I can program in it....
2015-03-15T22:17:43 < Tekkkz> haha
2015-03-15T22:18:35 < Tekkkz> when im done with avr i'll design a minimalistic board with hte STM32F042F6 for me
2015-03-15T22:19:19 < PaulFertser> Seems that lis331eb can't be bought anywhere anyway.
2015-03-15T22:19:41 < Tekkkz> yes

2015-03-15T22:20:02 < qyx_> lis331eb
2015-03-15T22:20:06 < qyx_> thats much different
2015-03-15T22:20:08 < Tekkkz> ahh
2015-03-15T22:20:10 < Tekkkz> y
2015-03-15T22:20:12 < Tekkkz>  i see
2015-03-15T22:20:14 < Tekkkz> ;(
2015-03-15T22:20:40 < qyx_> *very

2015-03-15T23:19:11 < karlp> tecdroid: if you're working with usb, you're kinda somewhat expected to know usb.  and lots of just _is_ copypasta from the specs.
2015-03-15T23:19:32 < tecdroid> okay.. try to keep that in mind
2015-03-15T23:19:44 < karlp> but if you want to add comments with standard sections for each of the descriptor structs, I'll see about merging it.
2015-03-15T23:20:08 < karlp> the device descriptors aren't really osmething that's documented by _libopencm3_ per se, it's something that's documented per example, perhaps,
2015-03-15T23:20:39 < karlp> the usb layer in libopencm3 is somewhat lower layer than, "here's a cdc-acm blob with some hooks"
2015-03-15T23:21:05 < karlp> now, BrainDamage, what sort of scooter should I rent if I'm goign to be in italy for a week?

2015-03-15T23:23:57 < BrainDamage> i'm not familliar much with scooters, but if you have a B-type license you can drive up to 125cc scooters, those are nicer because they allow access to highways and are generally more comfortable ( beware that nearly all highways have tolls )
2015-03-15T23:24:19 < BrainDamage> which area are you going to?
2015-03-15T23:24:39 < ehsanv> Hahaha... finally i wrote a software interface for sdram, with the help of logic analyser :D.. i believe in LA now,

2015-03-15T23:27:58 < karlp> hehe, the tinerent does not advise me to get a scooter, "Under practically no circumstances is using a scooter going to be anything other than an exercise in near-inevitable suicide. You can't use them on the motorways: off-motorway roads around Naples, while just challenging for car drivers, are simply deathtraps for novice scooter riders."
2015-03-15T23:29:31 < BrainDamage> karlp: well, it includes the negative things, like people disregarding basic road rules and safety :p ( also beware of scams, naples is pretty infamous even within italy itself )

2015-03-16T02:48:55 < dongs> its also not right angle

2015-03-16T02:49:19 < dongs> i suppose maybe there are SMD ones for ancient hdds

2015-03-16T06:17:57 < emeb_mac> wow - cheap
2015-03-16T06:18:15 < emeb_mac> is that footprint compatible with pulsejack?
2015-03-16T06:18:24 < dongs> and LAN8720A is even cheaper
2015-03-16T06:18:35 < dongs> emeb_mac: its ~standardish, its on the beagleboner etc
2015-03-16T06:18:54 < emeb_mac> ya
2015-03-16T06:19:04 < dongs> $1 ethernet solution
2015-03-16T06:19:39 < emeb_mac> did my first ethernet + stm32 recently - happy with it.
2015-03-16T06:19:54 < emeb_mac> lan8720 is fairly easy to use.
2015-03-16T06:20:12 < emeb_mac> needs a few more passives than the mitel phy though
2015-03-16T06:20:28 < dongs> what wats the mitel part#
2015-03-16T06:20:32 < dongs> micrel you mean
2015-03-16T06:20:35 < dongs> one of them wasnt avialble
2015-03-16T06:20:36 < emeb_mac> right
2015-03-16T06:20:43 < emeb_mac> zyp was looking at that
2015-03-16T06:20:47 < dongs> ah that one
2015-03-16T06:20:50 < dongs> yeah, cant get it
2015-03-16T06:20:54 < dongs> lan will have to do
2015-03-16T06:20:56 < emeb_mac> it only drives one of the leds on the magjack too
2015-03-16T06:21:01 < dongs> pffffft
2015-03-16T06:21:04 < dongs> no 10/100 led/??
2015-03-16T06:21:05 < emeb_mac> lan drives both
2015-03-16T06:21:08 < dongs> oh
2015-03-16T06:21:20 < emeb_mac> micrel only drives activity light
2015-03-16T06:21:41 < dongs> it would be cool if it actually banged teh led at line rate
2015-03-16T06:21:50 < dongs> and you could setup a photosensor near it and sniff traffic
2015-03-16T06:21:55 < emeb_mac> haha
2015-03-16T06:22:15 < dongs> i seem to recall reading something that did exactly that
2015-03-16T06:22:18 < dongs> some activity light thingy
2015-03-16T06:22:25 < dongs> but it was on something slower

2015-03-16T06:23:23 < dongs> that was from modem i guess
2015-03-16T06:23:38 < emeb_mac> right
2015-03-16T06:23:42 < emeb_mac> very slow

2015-03-16T06:24:21 < emeb_mac> dongs: if you gank the lan8720 schematic from the waveshare board be careful
2015-03-16T06:24:24 < dongs> original shitdot tweet
2015-03-16T06:24:29 < emeb_mac> they do some... strange shit there.
2015-03-16T06:27:48 < dongs> i think i had some tarduino shit to copy from
2015-03-16T06:29:30 < emeb_mac> ah
2015-03-16T06:30:20 < emeb_mac> here's mine: http://ebrombaugh.studionebula.com/embedded/stbone/stbone_schematic.pdf
2015-03-16T06:30:25 < emeb_mac> pg 3
2015-03-16T06:31:20 < emeb_mac> yellow LED polarity is wrong and R308 not needed.
2015-03-16T06:31:29 < emeb_mac> otherwise works great
2015-03-16T06:32:20 < dongs> by 'extra pasasives' you mean those 49.9R shits?
2015-03-16T06:32:27 < emeb_mac> ya
2015-03-16T06:32:39 < dongs> how important is C307 sounds redundant
2015-03-16T06:32:51 < dongs> isnt that just cap for internal vreg
2015-03-16T06:33:14 < emeb_mac> no that's matching impedance for the the ethernet
2015-03-16T06:33:23 < emeb_mac> bzzzt
2015-03-16T06:33:32 < emeb_mac> ignore that
2015-03-16T06:34:08 < dongs> no thats probly rxbias shit
2015-03-16T06:34:34 < emeb_mac> C307 isn't redundant - it's high-freq bypass in case the 0.1uf resonates
2015-03-16T06:34:47 < dongs> there's no 0.1uf there
2015-03-16T06:34:48 < dongs> there's 1uF
2015-03-16T06:34:55 < emeb_mac> right
2015-03-16T06:34:57 < emeb_mac> but still
2015-03-16T06:35:01 < dongs> thats a bypass?
2015-03-16T06:35:09 < emeb_mac> yep - internal regulator
2015-03-16T06:35:20 < dongs> right, but in that case its more like its output cap for internal regulator
2015-03-16T06:35:34 < emeb_mac> output bypass
2015-03-16T06:35:39 < emeb_mac> filter
2015-03-16T06:36:02 < dongs> ooo
2015-03-16T06:36:04 < dongs> if i have 1.2 on board
2015-03-16T06:36:06 < dongs> i can trash that
2015-03-16T06:36:10 < emeb_mac> you could *probably* get away without that 470, but why risk it
2015-03-16T06:37:01 < emeb_mac> aha - if you've got 1.2 already then just strap LED1 high instead of low
2015-03-16T06:37:16 < emeb_mac> disables internal reg
2015-03-16T06:37:22 < dongs> yeah just reading that
2015-03-16T06:38:34 < emeb_mac> waveshare & ST boards both used series termination resistors on the RX data and clock lines
2015-03-16T06:38:37 < emeb_mac> so I did too
2015-03-16T06:38:45 < emeb_mac> no idea if they're really needed though
2015-03-16T06:38:53 < dongs> heh china uSD socket is 25c
2015-03-16T06:38:57 < dongs> asking which one it actually is
2015-03-16T06:39:44 < dongs> i linked chinagirl to datasheet pdf for https://www.sparkfun.com/products/127
2015-03-16T06:39:46 < emeb_mac> everything is cheap in .cn
2015-03-16T06:39:48 < dongs> holy shit they want $4 for it
2015-03-16T06:40:06 < emeb_mac> stupid
2015-03-16T06:40:20 < emeb_mac> I get uSD sockets from DK for like $1
2015-03-16T06:40:38 < dongs> which part#?
2015-03-16T06:40:55 < dongs> i got those hirose shits
2015-03-16T06:41:06 < dongs> but thinking to standartize on something cehaper/more standard footprint
2015-03-16T06:41:23 < dongs> DM3D-SF here
2015-03-16T06:42:04 < dongs> ah hm same DM3 series has push/ejection type too
2015-03-16T06:42:09 < dongs> didnt know
2015-03-16T06:42:12 < emeb_mac> http://www.digikey.com/product-detail/en/1040310811/WM6357CT-ND/2804769
2015-03-16T06:42:16 < emeb_mac> $2
2015-03-16T06:42:17 < emeb_mac> derp
2015-03-16T06:42:49 < emeb_mac> I just use those because they're easy to hand-solder
2015-03-16T06:42:50 < dongs> ah the molex
2015-03-16T06:43:02 < dongs> ya thats not a very good one either
2015-03-16T06:43:02 < dongs> mkay
2015-03-16T06:43:24 < emeb_mac> doesn't have latch & eject mechanism
2015-03-16T06:43:36 < emeb_mac> just slide-in/slide-out
2015-03-16T06:43:50 < dongs> right
2015-03-16T06:43:51 < dongs> same as mine
2015-03-16T06:44:07 < dongs> i hope the china .25 one has eject, waiting to see what part# its a clone of
2015-03-16T06:45:06 < emeb_mac> that sparkfun one is awful for hobby stuff - pins are completely under the housing
2015-03-16T06:45:13 < emeb_mac> must reflow
2015-03-16T06:45:34 < dongs> thats what teh guy in comments saidid
2015-03-16T06:46:16 < emeb_mac> molex is easy to hand solder
2015-03-16T06:47:18 < dongs> http://i.imgur.com/iYFf9Sh.png chinaclone
2015-03-16T06:47:28 < dongs> looks like that one is also push type
2015-03-16T06:47:34 < dongs> and reflow-only but im not worried about that

2015-03-16T09:08:32 < dongs> clearly apple just targets teh users who are too dumb to know the diference, and based on the success of zano scam, there's a lot of them
2015-03-16T09:11:46 < upgrdman> some people just want things that only apple seems to offer. even something as simple as a GOOD display in a laptop. if you want ips, high res, antiglare coating, and not some widescreen trash... apple is like the only option.
2015-03-16T09:12:05 < upgrdman> dont know about the new macbook though... no ports... fuck that
2015-03-16T09:12:14 < dongs> .......... what
2015-03-16T09:12:22 < dongs> have you seen what screen is on faggotbook air?
2015-03-16T09:12:27 < dongs> its some 1388x768 shit
2015-03-16T09:12:42 < upgrdman> im not talking about the MBA, but apple in general
2015-03-16T09:12:54 < dongs> they have nothign that someone else doesnt do better, f or less
2015-03-16T09:13:02 < dongs> not a single product of theirs.
2015-03-16T09:13:16 < upgrdman> they cater to people who want better fit and finish than most of the windows crowd. of course, they charge a premium for it, but stil..
2015-03-16T09:13:31 < Tekkkz> good morning guys
2015-03-16T09:14:07 < upgrdman> i chuckle when i pick a windows laptop and creeks and grones like a 90 year old guy
2015-03-16T09:14:26 < upgrdman> keyboard flexes like some sort of pilaties girl
2015-03-16T09:14:57 < PeterM> and then you realize you shouldnt have bought a hp laptop from 2002
2015-03-16T09:15:29 < upgrdman> even the new stuff is like that
2015-03-16T09:16:00 < upgrdman> and the few windows laptops that are trying for quality charge apple prices, or higher.
2015-03-16T09:16:12 < zyp> wtf is a windows laptop?
2015-03-16T09:16:12 < upgrdman> and they're half-baked attempts too

2015-03-16T09:16:26 < zyp> why?
2015-03-16T09:16:45 < upgrdman> why? im guessing they're busy racing to the bottom
2015-03-16T09:17:14 < zyp> no, I mean, why is it a windows laptop?
2015-03-16T09:17:15 < upgrdman> cheap laptops are nice, but not everyone has price as their top concern
2015-03-16T09:17:37 < upgrdman> zyp, because they tend to have an os preinstalled, and its almost always windows?
2015-03-16T09:17:55 < zyp> that's dumb

2015-03-16T09:31:37 < Roklobsta> replace hdd, time machine restore or internet restore
2015-03-16T09:31:45 < englishman> replace hdd, sure
2015-03-16T09:32:05 < englishman> need to boot from usb or dvd to repair hard drive
2015-03-16T09:32:06 < Roklobsta> ok desolder hdd, solder new one on skillet.
2015-03-16T09:32:13 < englishman> self-install is incapable
2015-03-16T09:32:21 < englishman> cant make usb key on windows
2015-03-16T09:32:30 < zyp> haha
2015-03-16T09:32:35 < Roklobsta> ok why not internet restore
2015-03-16T09:32:42 < englishman> no internet
2015-03-16T09:32:43 < upgrdman> why can't people handle 17" laptops? they fit easily in backpacks, bags, luggage, etc. is it the weight? oh ya, that reminds me: why the fuck is windows and linux both suck ass at battery life.
2015-03-16T09:32:46 < englishman> on install screen
2015-03-16T09:32:50 < zyp> that reminds me of that time I wanted to install windows from usb
2015-03-16T09:32:58 < englishman> its booting from the osx install shit
2015-03-16T09:33:00 < zyp> couldn't make installer usb key without windows
2015-03-16T09:33:05 < dongs> yeah, you mean like last ~5 years?
2015-03-16T09:33:31 < Tekkkz> zyp: but isnt it possible to use virtual machine on win to make one?
2015-03-16T09:34:13 < qyx_> i am reading you and it seems that os innovation stopped like 10 years ago
2015-03-16T09:34:44 < Roklobsta> so you didn't make a time machine backup before upgrade.
2015-03-16T09:34:59 < zyp> Tekkkz, you don't need to try solving a problem I had like two years ago
2015-03-16T09:35:26 < Roklobsta> pull down pants, expose bits, hold 2 bricks, rapidly enclose bits between bricks.
2015-03-16T09:35:37 < Tekkkz> okok zyp but doenst have englishman the same problem now?
2015-03-16T09:36:06 < englishman> important stuff is backed up of course, since its normal that simple task like upgrading os should lose all data on hd
2015-03-16T09:36:09 < englishman> in mac land
2015-03-16T09:36:36 < zyp> heh
2015-03-16T09:36:57 < zyp> that's silly arguing
2015-03-16T09:37:06 < zyp> important stuff should be backed up at any time
2015-03-16T09:37:14 < zyp> regardless of what you are doing
2015-03-16T09:37:18 < qyx_> important stuff shouldnt be on a notebook
2015-03-16T09:37:42 < Roklobsta> for a proprietory OS I do like how Apple don't carry on with license key bullshit
2015-03-16T09:38:04 < Roklobsta> though i guess mac hardware is a giant security dongle
2015-03-16T09:38:09 < Tekkkz> Roklobsta: what do you mean?
2015-03-16T09:38:24 < zyp> uh
2015-03-16T09:38:27 < Tekkkz> with license
2015-03-16T09:38:34 < zyp> I'm runing OS X on non-apple hardware right now
2015-03-16T09:38:44 < Roklobsta> i plugged a 4G dongle into my Win7 laptop the other day and now I fucking have to reregister Win7 on the phone.
2015-03-16T09:39:08 < Roklobsta> i haven't done it yet and i am booting linux instead.  fuck off ms.
2015-03-16T09:39:08 < Tekkkz> zyp: is t possible to install ox x on other hardware ?
2015-03-16T09:39:22 < Roklobsta> Tekkkz: though i guess mac hardware is a giant security dongle
2015-03-16T09:39:25 < PeterM> Roklobsta, talk to Daz
2015-03-16T09:39:30 < jpa-> i have one inside virtualbox on my pc, but it doesn't work 100% perfectly
2015-03-16T09:39:45 < zyp> Tekkkz, sure
2015-03-16T09:39:59 < Tekkkz> is it easy or complicated
2015-03-16T09:40:06 < Roklobsta> i tried that vmware hack a while back, but whop de doo.
2015-03-16T09:40:40 < zyp> I've been running this as my main computer for almost three years now, no big problems
2015-03-16T09:41:04 < Tekkkz> would you recommend using it instead of arch linux?
2015-03-16T09:41:24 < Roklobsta> mac schmack
2015-03-16T09:41:39 < zyp> I would recommend that you do what the fuck you want
2015-03-16T09:41:45 < Roklobsta> i do
2015-03-16T09:41:49 < Tekkkz> i jsut mean do you like it?
2015-03-16T09:42:05 < Tekkkz> and is it difficult to install or just insert usb and installing?
2015-03-16T09:42:12 < Tekkkz> or are there any tricks necesary?
2015-03-16T09:42:13 < zyp> yes, I use OS X because it's like linux, except it has GUI stuff that actually works
2015-03-16T09:42:25 < qyx_> uhm
2015-03-16T09:42:29 < Roklobsta> though, i did make a master mac image for a school last week and the 'disk utilities' make cloning a cinch.
2015-03-16T09:42:30 < qyx_> sometimes
2015-03-16T09:42:36 < PeterM> the hardware compatibility can be a bit rubbish tho on OSX86

2015-03-16T09:43:03 < Roklobsta> zyp: whatever.  KDE works just fine except when it doesn't.
2015-03-16T09:43:21 < Tekkkz> haha
2015-03-16T09:43:21 < PeterM> Roklobsta, works every time, 30% of the time
2015-03-16T09:43:28 < dongs> so KDE doesnt work?
2015-03-16T09:43:32 < qyx_> the same apply to osx and win8.1 with dual monitors
2015-03-16T09:43:58 < zyp> what about dual monitors?
2015-03-16T09:44:01 < Roklobsta> mostly.  this week 'shut down' get's me nowhere so I havce to ctrl-alt-f1 then sudo poweroff
2015-03-16T09:44:04 < Tekkkz> how expensive is os x?
2015-03-16T09:44:09 < englishman> currently on win 8.1 with 4 monitors, works fine
2015-03-16T09:44:12 < zyp> I've been using dual monitors with OS X for as long as I've used OS X
2015-03-16T09:44:15 < dongs> windows supported dual monitors since win98SE
2015-03-16T09:44:32 < dongs> ive used it with some random AGP + PCI video card.
2015-03-16T09:44:38 < qyx_> the metro thing initialization with arrow hints doesn't work
2015-03-16T09:44:40 < dongs> good luck trying that shit with linsux in 1999
2015-03-16T09:44:49 < dongs> qyx_: wut
2015-03-16T09:44:56 < Roklobsta> i'll concede desktop land in 2015 on linux isn't robust
2015-03-16T09:45:06 < Tekkkz> wait, is osx free?
2015-03-16T09:45:11 < Roklobsta> 2025 is looking hopeful
2015-03-16T09:45:15 < dongs> free if  y ou own gay hardware
2015-03-16T09:45:29 < qyx_> dongs: we were not able to get rid of it because it displayed weirdly and on different monitor
2015-03-16T09:45:29 < Tekkkz> and how to get it for "my" hardware?
2015-03-16T09:45:31 < Roklobsta> Tekkkz: yes if you have a giant iMac/macbook/macmini dongle.
2015-03-16T09:45:39 < zyp> Tekkkz, how to google
2015-03-16T09:45:46 < Tekkkz> i dont fidn anything
2015-03-16T09:45:55 < zyp> google better
2015-03-16T09:46:35 < Roklobsta> in my day job i deal with macs and i am underwhelmed.
2015-03-16T09:46:57 < Roklobsta> sometimes i am a little bit whelmed.

2015-03-16T17:03:46 < vvirag> hi! i'm still quite new with stm32 microcontrollers, and would appreciate advice from the experienced ones: I'm using an stm32f407vgt6 (discovery board), but I would like to have a much smaller alternative - in a way that the code could be still compatible. I use ADC/DAC/DMA/timer functionalities, so basically I look for something, which also has these.. Does my question make any sense? :)

2015-03-16T17:06:15 < vvirag> maybe i was not clear. i would like to minimize the physical dimensions of the board, without having my own pcb
2015-03-16T17:06:51 < vvirag> stm32f0 on the other hand is cortex-m0, and i wanted to stick with cortex-m4 because of the better dsp support

2015-03-16T17:11:15 < karlp> none of STs boards are going to be substantially smaller.
2015-03-16T17:11:32 < karlp> they're looking for some existing "small" m4 board.

2015-03-16T17:16:48 < vvirag> i don't want to build my own stuff, because i've never done, and based on my deadline maybe this is not the best time to learn :)
2015-03-16T17:17:07 < vvirag> maybe later
2015-03-16T17:17:21 < vvirag> i think i might go with this one: http://www.mikroe.com/downloads/get/1946/mini_m4_stm32_user_manual.pdf
2015-03-16T17:17:55 < jpa-> i wonder why they have their own usb hid bootloader instead of using the STM32F4 built-in one
2015-03-16T17:21:01 < karlp> compatible with their pic ones probably.
2015-03-16T17:21:11 < karlp> you're meant to buy into the whole mikroe worldview
2015-03-16T17:21:19 < karlp> their compiler, their deve environment, their boards, their tools.
2015-03-16T17:22:24 < emeb> wonder if it even brings out the SWD pins?
2015-03-16T17:23:22 < vvirag> karlp, what do you mean by that? i -naively- thought, that if i use gcc-arm compiler, then i could still use for that mikroe-mini
2015-03-16T17:24:33 < emeb> sure you can - their bootloader just uses .hex files which you can create with gcc
2015-03-16T17:24:35 < Steffanx> yes it does emeb
2015-03-16T17:24:43 < Steffanx> pa13/14
2015-03-16T17:24:46 < vvirag> oh, okay
2015-03-16T17:24:55 < emeb> but looking at the schematic it seems that the BOOT0 pin is permanently grounded
2015-03-16T17:24:57 < jpa-> emeb: it does
2015-03-16T17:25:08 < emeb> so you can't use the ST USB DFU bootloader
2015-03-16T17:26:22 < emeb> their USB port is also set up so that it doesn't support USB Host mode. Device only, even tho the F415 is capable of that.
2015-03-16T17:27:16 < Steffanx> it had to be 100% compatible with the pic boards i guess
2015-03-16T17:27:25 < emeb> makes sense
2015-03-16T17:27:29 < vvirag> so what does this mean? (sorry for the stupid questions, but i'm a little bit lost). So I can still use my gcc-arm compiler, so far so good. But then how should i flash it?
2015-03-16T17:27:42 < emeb> you need their bootloader app
2015-03-16T17:28:08 < Steffanx> or your discovery and use swd.
2015-03-16T17:28:09 < emeb> and their bootloader code is always resident in flash
2015-03-16T17:28:20 < emeb> right - with flywires to the right pins

2015-03-16T21:18:23 < Tekkkz> would you agree if i say that its better to use avr at little projects cause cheaper and less pwerful?
2015-03-16T21:18:53 < englishman> cheaper than wat
2015-03-16T21:18:59 < englishman> uses less power than what
2015-03-16T21:19:11 < englishman> i dont think we need to convice you of anything
2015-03-16T21:19:20 < englishman> continue to use avr if you want to
2015-03-16T21:19:40 < Tekkkz> nono
2015-03-16T21:19:51 < Tekkkz> i have actually my last avr project and then i will use stm32

2015-03-17T00:37:57 < qyx_> it depends, but probably you want output pushpull and no pullup/pulldown
2015-03-17T00:38:32 < qyx_> pullup/down has only meaning if the pin is configured as input or output opendrain
2015-03-17T00:39:58 < ds2> does the hw let you enable pull's for outputs?
2015-03-17T00:40:57 < qyx_> i don't know for pushpull, i have never had such interesting needs
2015-03-17T00:41:06 < qyx_> but yes for opendrain
2015-03-17T00:48:15 < ds2> for OD it makes sense

2015-03-17T05:20:50 < jadew> I watched this several times tonight and can't get enough: https://www.youtube.com/watch?v=VeZXQf77hhk
2015-03-17T05:20:51 < jadew> PHP Parse error: parse error in SCRIPT on line 1
2015-03-17T05:21:06 < jadew> ignore the parse error, stupid script
2015-03-17T05:21:46 < jadew> and I think I'm gonna watch a disney classic soon
2015-03-17T05:22:01 < dongs> looks like unfunny american rap
2015-03-17T05:22:20 < jadew> R2COM, rap battle between cindarella and belle
2015-03-17T05:22:35 < jadew> very well made
2015-03-17T05:22:54 < jadew> belle - the character from the beauty and the beast
2015-03-17T05:22:55 < dongs> yes, but its (c)rap so that automatically disqualifies it
2015-03-17T05:23:04 < jadew> nah, it's really fun

2015-03-17T05:25:18 < jadew> I can't explain funny
2015-03-17T05:25:48 < jadew> I suppose you have to know the stories too
2015-03-17T05:26:36 < jadew> I saw a cinderalla based movie like... two days ago
2015-03-17T05:27:02 < jadew> nah, regular movie

2015-03-17T05:36:03 < jadew> anyway, I love fairytales and I didn't watch the disney movie either, but we were told the story in kindergarden
2015-03-17T05:39:21 < jadew> there was another one with some kids and an evil step mom and they threw her in the stove
2015-03-17T05:39:32 < jadew> another one where they tortured her
2015-03-17T05:39:47 < jadew> I guess disney never made movies out of these tho
2015-03-17T05:40:06 < emeb_mac> grimm and dark
2015-03-17T05:41:08 < jadew> I only heard about the red army a couple of years back
2015-03-17T05:44:16 < jadew> I was playing EVE online and was going to war with some russians and the guys in my fleet were joking that the russians listen to red army songs in fleet comms
2015-03-17T05:45:12 < jadew> had to look it up
2015-03-17T05:46:45 < emeb_mac> my mom grew up in .de during WWII
2015-03-17T05:46:58 < emeb_mac> they made a lot of jokes about the russian army
2015-03-17T05:47:31 < emeb_mac> yes - they were terrified of them. had to do something to make light.
2015-03-17T05:47:40 < jadew> they passed through romania and I heard they were jackasses
2015-03-17T05:49:06 < jadew> my grandmother told me that they would go into people's homes, drink, eat and afterwards spill all the remaining wine
2015-03-17T05:49:14 < jadew> we weren't even at war with them
2015-03-17T05:50:08 < jadew> I'm not familiar with the history of the ww2, but it sounded like they were doing whatever they wanted in here
2015-03-17T05:51:14 < jadew> so romania was pretty much conquered?
2015-03-17T05:51:37 < jadew> that too
2015-03-17T05:52:10 < jadew> not everyone is happy about that
2015-03-17T05:52:44 < jadew> on the other hand it's a safe move
2015-03-17T05:53:07 < jadew> it's not like we can stand our ground and hold off any attack
2015-03-17T05:53:09 < jadew> from anyone
2015-03-17T05:54:04 < jadew> it's not gonna happen
2015-03-17T05:54:51 < jadew> chances of that happening are lower than that of russia deciding they want a new piece of land and getting it
2015-03-17T05:56:45 < jadew> I suppose they'd want Ukraine first
2015-03-17T05:59:27 < jadew> I don't know, if they want access to europe, it seems like a straight line
2015-03-17T06:00:43 < jadew> well, technically if any NATO country is attacked, they all go to war
2015-03-17T06:00:56 < jadew> which is probably why we joined NATO
2015-03-17T06:01:16 < jadew> nobody will attack us unless there's already a world war going on, in which case it doesn't matter anymore
2015-03-17T06:03:34 < jadew> the only downside to this is that in case someone decides to start a world war, the anti-missile bases will be the first ones to be targetted
2015-03-17T06:04:29 < jadew> you don't need to wipe an entire country in order to destroy them :)
2015-03-17T06:07:44 < jadew> I'm not worried about it, it's not gonna happen anyway

2015-03-17T08:22:38 < dongs> wouldnt that heat up>?
2015-03-17T08:22:51 < dongs> to get reasonable adc voltage it would need to be like 1R
2015-03-17T08:23:23 < dongs> iwht 0.1R i get some useless shit like ~50lsb
2015-03-17T08:23:45 < jpa-> 10 milliohms + oversampling would get you the 100mA resolution and dissipate 0.002 W.. i would probably use 0.1 ohms
2015-03-17T08:23:47 < zyp> reasonable? you're talking about less than three bits of resolution
2015-03-17T08:23:49 < jpa-> oversample
2015-03-17T08:24:09 < dongs> ya? hm i thought i calculated with 0.1R and it would have been unreasonable
2015-03-17T08:24:11 < dongs> ill look over it again then
2015-03-17T08:25:08 < jpa-> 0.1 ohms should give you 100mA resolution even if you have terrible +-5 noise and no oversampling

2015-03-17T15:26:43 < Steffanx> We were only allowed to have fun with novell network chat crap.
2015-03-17T15:26:58 < Steffanx> @ highschool
2015-03-17T15:27:11 < ReadError> some IT guy in my school district
2015-03-17T15:27:22 < ReadError> fucked up and sent some message to the entire district
2015-03-17T15:27:35 < ReadError> and it had 'fuck' in it
2015-03-17T15:27:43 < ReadError> so it popped up on every computer
2015-03-17T15:27:46 < Steffanx> Actually that's what we did too, just because some network admin enabled the chat by accident :P
2015-03-17T15:27:56 < karlp> baird was that the +++\ATH0; or somthing?
2015-03-17T15:28:10 < karlp> hooray for modems not escaping escapes....
2015-03-17T15:28:57 < baird> A Uni X Term lab used to have everything "xhost +" .. The guys in the Postgrad Apollo lab would xv-root the public terminal's backgrounds with porn. Good times.
2015-03-17T15:30:13 < akaWolf> Steffanx is doing something at Qt...
2015-03-17T15:30:14 < baird> karlp: Not much like it. It would crash every ?4.2BSD-based TCP/IP stack.. which most real systems obsoleted years earlier.. except Microsoft.
2015-03-17T15:30:40 < Steffanx> i lurk in #qt if that's what you mean akaWolf
2015-03-17T15:30:49 < akaWolf> yeah
2015-03-17T15:31:29 < baird> A funny thing was at the time, MS were claiming up-and-down that they'd rewritten their networking from scratch to claim I.P licencing rightd..
2015-03-17T15:32:39 < karlp> baird: yar, you ping with the payload of +++ath0, and the ping reply going out "looked" like the user had entered it.

2015-03-17T15:33:39 < kakeman> early internet times m ust been weird
2015-03-17T15:34:03 < Steffanx> Yeah, was the entire internet based on trust ( or something ) back then?
2015-03-17T15:34:07 < baird> The Ping of Death then was packets of >32kB
2015-03-17T15:34:11 < kakeman> yes
2015-03-17T15:34:36 < kakeman> nowdays internet is about untrust
2015-03-17T15:35:46 < baird> An early DDoS was to have a compressed-PPP link, and pump out large ping packets
2015-03-17T15:36:48 < dongs> heh

2015-03-17T15:38:41 < kakeman> if i send stream of UDP packets directly from board to my computer do i need to number them or can I trust packets are recorded in order received?
2015-03-17T15:38:42 < dongs> wahts the significance of 4 switch
2015-03-17T15:39:00 < dongs> kakeman: udp is not guaranteed to be in order or arrive
2015-03-17T15:39:03 < dongs> you need toh ave your own header

2015-03-17T15:39:50 < kakeman> if I have direct cable to board to computer can my computer actually change order of packets?
2015-03-17T15:40:02 < baird> kakeman: you can't. look at the name of the protocol
2015-03-17T15:40:28 < karlp> U == user, not unreliable

2015-03-17T15:40:55 < kakeman> ok is there easy simple solution?
2015-03-17T15:41:01 < Steffanx> use tcp ?
2015-03-17T15:41:11 < kakeman> maybe
2015-03-17T15:41:13 < karlp> kakeman: the udp rfc even starts with, "Applications requiring ordered reliable delivery of
2015-03-17T15:41:16 < karlp> streams of data should use the Transmission Control Protocol (TCP)"
2015-03-17T15:41:18 < baird> I got LIED to at one point..
2015-03-17T15:41:34 < karlp> baird: better to think of it as unreliable, but it's not what it stands for :)
2015-03-17T15:41:51 < kakeman> I just want shitload of bitstream from board to computer and recorded in order
2015-03-17T15:41:57 < baird> I wonder if the l33t-est of hackerz still use FSP.
2015-03-17T15:42:03 < kakeman> faster is faster
2015-03-17T15:42:04 < englishman> bitbang phy direct
2015-03-17T15:42:07 < karlp> man, rfc768 is tiny.
2015-03-17T15:42:24 < kakeman> bitbang directly to cat5
2015-03-17T15:42:24 < dongs> haha
2015-03-17T15:42:43 < Steffanx> some AVR does it.
2015-03-17T15:42:49 < Steffanx> *AVR project

2015-03-17T15:44:02 < baird> Hah. I wrote a system for multiplex communcation between a C64 and a SYM1 a few years ago, with nearly the same format.. (checksum was at the end)
2015-03-17T15:44:07 < kakeman> I rather number my UDP packets I think it will be lighter
2015-03-17T15:44:23 < karlp> "I hope you know what you're doing"
2015-03-17T15:44:27 < dongs> if I have both 5V and 12V, and using a switcher to step to 3.3V, which is better go from 12V or 5V/
2015-03-17T15:44:39 < karlp> (before you know it, you'll have reimplemented a bunch of tcp)
2015-03-17T15:44:46 < Steffanx> also keep i mind you could loose packets kakeman
2015-03-17T15:44:50 < dongs> i think i recall hearing that 12V woould be better
2015-03-17T15:45:12 < englishman> depends on your switcher
2015-03-17T15:45:50 < dongs> im about to look at effeicencty graphs
2015-03-17T15:46:10 < englishman> does efficiency matter in the end procuct
2015-03-17T15:46:18 < dongs> no
2015-03-17T15:46:21 < Steffanx> The 5V also comes from some switcher?
2015-03-17T15:46:23 < englishman> then use whatever is easier
2015-03-17T15:46:41 < dongs> Steffanx: no, 5V is plugged into the board with PC molex shit.

2015-03-17T15:47:12 < englishman> so it comes from atx switcher
2015-03-17T15:47:15 < dongs> yeah
2015-03-17T15:47:21 < dongs> dumbfuck datasheet only shows efficiency for 12V in
2015-03-17T15:48:17 < kakeman> efficiency aproaching 0% at Vmax
2015-03-17T15:48:26 < dongs> more like vabsmax
2015-03-17T15:48:30 < jpa-> dongs: all other things equal, i would say that from 12V requires smaller coil, while from 5V gives less noise
2015-03-17T15:48:46 < jpa-> small efficiency difference also
2015-03-17T15:48:51 < dongs> hmm and neither really matter
2015-03-17T15:48:56 < jpa-> (all of these differences are quite tiny anyway)
2015-03-17T15:49:50 < Steffanx> So go for cheapest solution
2015-03-17T15:50:12 < dongs> its just a matter of routing 12 or 5 to same switcher.
2015-03-17T15:50:20 < dongs> maybe ill do 12, and then find reason to not need 5 at all
2015-03-17T15:50:28 < dongs> then i can make the 12V plug smaller.
2015-03-17T15:50:59 < jpa-> (hmm, actually for buck regulator, doesn't matter for coil size; not so sure about noise)
2015-03-17T15:54:46 < kakeman> if I know remote mac address do I need ARP?

2015-03-17T15:56:55 < kakeman> no I don't need
2015-03-17T15:57:06 < kakeman> one direction flood
2015-03-17T15:57:34 < dongs> is tehre any power to harvest off ethernet if PoE is not involved?
2015-03-17T15:57:57 < dongs> im guessing no
2015-03-17T15:58:12 < kakeman> not enought to drive ethernet
2015-03-17T15:58:19 < kakeman> I bet
2015-03-17T15:58:34 < jpa-> you can charge a supercap and communicate occassionally
2015-03-17T15:58:53 < dongs> http://electronics.stackexchange.com/questions/55617/how-could-i-power-an-ic-over-the-ethernet
2015-03-17T15:59:16 < jpa-> why UDP flood? you'll need a gigabit device to do anything useful that way
2015-03-17T15:59:38 < jpa-> IMO much more devious is ARP poisoning, i.e. reply to ARP queries with false addresses causing random connection failures

2015-03-17T19:54:01 < edmoore> about 190 sensor channels in total
2015-03-17T19:54:01 < kakeman> those taps must be quite small
2015-03-17T19:54:15 < edmoore> distributed among boxes of 16 channels, each having an stm32f407
2015-03-17T19:54:22 < edmoore> which dumps back over ethernet
2015-03-17T19:54:22 < kakeman> thrust scale elements?
2015-03-17T19:54:29 < edmoore> the taps are small, the engine is also fairly sizeable
2015-03-17T19:54:45 < edmoore> yeah we have a 6-axis load-cell to measure thrusts and any off-axis stuff
2015-03-17T19:54:56 < kakeman> :)
2015-03-17T19:55:02 < qyx_> much data
2015-03-17T19:55:31 < kakeman> edmoore: what kind of budgets we are talking about in this kind of projects?
2015-03-17T19:55:36 < edmoore> we're flirting with the limits of nozzle stability (to confirm CFD results as much as anything) so the off-axis stuff is very useful for corroborating unstable separation in the nozzle
2015-03-17T19:55:48 < edmoore> kakeman, that's probably commercially sensitive
2015-03-17T19:55:54 < kakeman> yes
2015-03-17T19:56:07 < edmoore> but sort of $1M < x < $10M
2015-03-17T19:56:28 < kakeman> testrigging own rocket engines would be nice hobby
2015-03-17T19:56:38 < edmoore> it was a hobby
2015-03-17T19:56:40 < edmoore> became a job

2015-03-17T20:00:39 < edmoore> but yes we have a bit of a happy niche because we understand electronics and rocket engines
2015-03-17T20:00:44 < edmoore> and especially the interface between them
2015-03-17T20:00:47 < Getty> kakeman: why so serious???
2015-03-17T20:00:54 < edmoore> usually people understand strictly one or the other and fear the other
2015-03-17T20:01:02 < Laurenceb> I'll just leave this here   http://i.imgur.com/HEvIAzT.jpg
2015-03-17T20:01:04 < edmoore> so being able to do both has served well
2015-03-17T20:01:41 < Laurenceb> I think its sensible to fear rocket engines
2015-03-17T20:01:56 < edmoore> I respect them
2015-03-17T20:02:06 < edmoore> our safety philosophy is to assume every test will result in an explosion
2015-03-17T20:02:11 < edmoore> and design all the systems around that
2015-03-17T20:02:15 < edmoore> that way nothing is surprising
2015-03-17T20:02:37 < edmoore> and you automatically have things like isolated propellant feeds on separate sides of blast-walls that close in the event of a power failure or whatever
2015-03-17T20:02:53 < edmoore> because you've thought about what happens if the power (or the firing officer) get taken out
2015-03-17T20:02:55 < kakeman> is there anything to learn about rocket engine nozzle design anymore?
2015-03-17T20:03:08 < edmoore> yes
2015-03-17T20:03:12 < edmoore> a lot
2015-03-17T20:03:16 < edmoore> but i can't go into much detail
2015-03-17T20:03:24 < edmoore> it's public that we're working on altitude-compensating nozzles
2015-03-17T20:03:27 < edmoore> so it's all related to that
2015-03-17T20:04:04 < kakeman> it means moving parts?
2015-03-17T20:04:10 < kakeman> in nozzle?
2015-03-17T20:04:37 < edmoore> this answer can be gleaned from the academic literature: no, not strictly
2015-03-17T20:04:54 < edmoore> there are other ways involving very careful geometry

2015-03-17T20:05:38 < edmoore> as a starting point see expansion-deflection nozzles and aerospikes
2015-03-17T20:05:52 < kakeman> ok thats cool
2015-03-17T20:07:47 < edmoore> if you can crack that nut then you have a very useful addition to the problem of making an engine that can go from ground to orbit as a single stage
2015-03-17T20:08:11 < edmoore> whereas with expendable stages you can just tailor each stage's nozzles to their more limited pressure-range
2015-03-17T20:09:11 < kakeman> less weight

2015-03-17T22:06:43 < qyx_> but there may be a difference - li-ion cells are usually contained in a rigid housings with gas vents
2015-03-17T22:07:03 < qyx_> li-po cells are packaged in a foil which can expand/tear in an overpressure condition
2015-03-17T22:07:29 < qyx_> so you probably risk the whole thing exploding if it is hermetically sealed

2015-03-18T00:06:44 < kakeman> can you utilize all 3?
2015-03-18T00:06:51 < bvernoux> a good example : 1 Core for LCD (M0), 1 Core for computation (M4F) and last core (M0s) for peripheral SGPIO/SPI
2015-03-18T00:07:01 < bvernoux> and you have a killer product
2015-03-18T00:07:18 < bvernoux> and I have forgotten REAL ADC High SPeed 12bits up to 80MSPS !!
2015-03-18T00:07:51 < bvernoux> just for info ADC 12bits 20MSPS cost is 2 time bigger than the LPC4370 ;)
2015-03-18T00:08:04 < englishman> meanwhile nucleo is 1/5 price of arduino zero and has stm32f1 debugger
2015-03-18T00:08:27 < bvernoux> yes nucleo and other stm32fx are 10x better than arduino stuff ...
2015-03-18T00:09:19 < bvernoux> arduino is good to learn how work basic embedded stuff but for serious project it's a no go
2015-03-18T00:10:08 < kakeman> you shouldn't take that path
2015-03-18T00:10:18 < bvernoux> anyway we see now all cool project quad copter and other stuff do NOT use arduino ;)
2015-03-18T00:10:57 < bvernoux> but they are using STM32Fx and mainly the STM32F405 which is small /easy to solder (LQFP64 or LQFP100) and fast
2015-03-18T00:11:03 < scrts> can you make it IQ?
2015-03-18T00:11:11 < scrts> I mean it's a single channel only?
2015-03-18T00:11:21 < bvernoux> about what ?
2015-03-18T00:11:28 < bvernoux> ADCHS LPC4370 ?
2015-03-18T00:11:42 < bvernoux> there is 1 differential channel
2015-03-18T00:11:46 < bvernoux> fully diff
2015-03-18T00:11:56 < bvernoux> and the other channel are single ended
2015-03-18T00:12:09 < bvernoux> and no it's not IQ internally just RAW ADC samples

2015-03-18T00:43:03 < Getty> yes, its mean to be airplane ;) not cargo on a ship ;)
2015-03-18T00:44:58 < zyp> what's this proposal? «let's start a new airline that'll pay pilots even less»?
2015-03-18T00:45:40 < Getty> its ryanair http://www.wort.lu/en/business/transatlantic-flights-rumours-rife-of-14-euro-ryanair-flights-to-us-5507eb750c88b46a8ce5591c
2015-03-18T00:45:47 < zyp> of course it's ryanair
2015-03-18T00:45:52 < Getty> yeah ;)
2015-03-18T00:46:05 < Getty> who else but quagmire ;)
2015-03-18T00:46:06 < zyp> I flew ryanair once
2015-03-18T00:46:09 < zyp> once.
2015-03-18T00:46:12 < BrainDamage> "passengers will be held in place by nipple clamps"
2015-03-18T00:47:31 < zyp> sitting all the way across the atlantic on a ryanair plane sounds like a pretty horrible experience
2015-03-18T00:47:38 < Getty> yeah
2015-03-18T00:47:53 < zyp> especially if they'll still have the seats that won't recline
2015-03-18T00:48:02 < Getty> but i am more interested in what the plane is like, i mean, they cant use the same planes i know of them
2015-03-18T00:48:12 < BrainDamage> it might be useful to force the hand of other companies to lower the prices a bit
2015-03-18T00:48:21 < Getty> its hard to imagine a gigantic cheap box
2015-03-18T00:48:31 < zyp> why? transatlantic flights are plenty cheap already
2015-03-18T00:49:09 < Getty> yeah but the planes i knew of transatlantic flights are always far above ryanair quality
2015-03-18T00:49:30 < Getty> i just try to imagine something so big like a transatlantic plane, but with the ryanair quality
2015-03-18T00:49:40 < zyp> I don't want to.
2015-03-18T00:50:36 < Getty> i remember, one of those flights i had from brazil to europe had pretty bad air conditions, and you really saw the wing going up and down, only the trust in the airline kept me sane.... ;)
2015-03-18T00:52:14 < Getty> hahaha found another article saying: "It's dependent on attaining viable long-haul aircraft and we estimate that's four to five years away,"
2015-03-18T00:52:23 < Getty> so this is ACTUALLY the core of the problem why its not there yet ;-)
2015-03-18T00:53:06 < zyp> sounds like what they're saying is that they're waiting for other airlines to upgrade their aircraft so they can snag the old ones
2015-03-18T01:02:19 < Steffanx> i read somewhere some norwegian airliner is currently the cheapest to go to newyork
2015-03-18T01:03:59 < Steffanx> Norwegian Air Shuttle, london to ny for 208eur, where ryanair is expected to be 138e
2015-03-18T01:04:23 < Steffanx> but that NAS stuff costs them more than they get -_-

2015-03-18T01:10:12 < Getty> so the planes they want must be actually constructed first ;)
2015-03-18T01:10:35 < Getty> they probably wanna use standing cocoons for the passanger

2015-03-18T01:16:57 < GargantuaSauce> and there was something like a 20% survival rate
2015-03-18T01:17:07 < zyp> Steffanx, NAS is shit though
2015-03-18T01:18:32 < zyp> they're kinda going the way of ryanair, to the point of having a bunch of aircraft registered in ireland because that allows them to act shittier than what norwegian laws would allow

2015-03-18T01:20:54 < zyp> their pilots just had a two week long strike because they were opposed to some new shitting on their terms
2015-03-18T01:27:35 < zyp> that said, I'm still willing to fly NAS, that's more than I can say about ryanair :p
2015-03-18T01:28:04 < Steffanx> hmm, my trip to finland went pretty smooth.
2015-03-18T01:28:11 < Steffanx> with ryanair
2015-03-18T01:28:26 < Steffanx> but it was only a 1.5 hour flight, so no big deal
2015-03-18T01:29:45 < zyp> I flew to london with them in 2007, they fucked up their plane and had to delay the flight until the next day
2015-03-18T01:29:58 < zyp> which is of course a thing that can happen
2015-03-18T01:30:55 < zyp> took half a year before they would refund me for the hotel stay that added to my trip
2015-03-18T01:31:36 < Steffanx> ah fun times
2015-03-18T01:32:16 < zyp> first they tried the «this happened for a reason outside our control, and therefore you are not entitled to compensation» excuse
2015-03-18T01:32:22 < zyp> which was an outright lie
2015-03-18T01:34:24 < zyp> and I'm not interested in supporting companies like that, so I'd rather pay more to travel with a competitor :p
2015-03-18T01:34:55 < zyp> which is not hard to rationalize when ryanair are also flying to/from inconvenient airports

2015-03-18T04:25:19 < dongs> im not sure, I bought some for zyp
2015-03-18T04:25:21 < dongs> and got some left over
2015-03-18T04:25:32 < dongs> basically I think any SMT pinheader would have to be reflow rated
2015-03-18T04:25:41 < dongs> cuz it has to go through the oven
2015-03-18T04:26:06 < dongs> those melt very fast

2015-03-18T04:30:34 < dongs> or do you mean just 2 pin like single row
2015-03-18T04:30:54 < dongs> i'd say very expensive then.
2015-03-18T04:31:14 < dongs> so youre saying
2015-03-18T04:31:17 < dongs> those are high temp?
2015-03-18T04:31:24 < dongs> where does it say that
2015-03-18T04:31:34 < dongs> cuz of HLF? in part#?
2015-03-18T04:32:06 < dongs> i see
2015-03-18T04:32:54 < dongs> zyp's shit has been through hundreds of reflow cycles
2015-03-18T04:32:57 < dongs> and its fine
2015-03-18T04:33:12 < dongs> they're sitting on the oven floor, and rising pcb around 8mm off of it
2015-03-18T04:34:14 < dongs> tehy were just china grabbag stuff 2x13 SMT 2.54mm pitch
2015-03-18T04:34:21 < dongs> like i said, SMT would generally mean high-temp stuff.

2015-03-18T06:44:06 < ds2> space
2015-03-18T06:44:32 < ds2> I'd love a 9 axis chip + BLE + M0 in a package around that size
2015-03-18T06:44:59 < ds2> the MPU9xxx isn't that far from that.
2015-03-18T06:45:25 < ds2> in what way?
2015-03-18T06:45:57 < ds2> I have used them. seems fine other hten their damn DMP
2015-03-18T06:46:10 < ds2> it matches
2015-03-18T06:46:22 < ds2> at least the MPU6xxx series

2015-03-18T06:47:12 < ds2> i used them for a dev board for such folks. the specs in those products match the specs fine

2015-03-18T08:17:25 < Getty> there is no magical "trick" that makes it more value as the production cost
2015-03-18T08:17:27 < jpa-> $14 can buy good headphones IMO, even though $14 headphones probably cost $6 to make
2015-03-18T08:17:42 < Getty> it is really a shitty cheap produced headphone with "dr. dre" written on it
2015-03-18T08:17:51 < Getty> that was from start on the plan, its not like they dont know what they make
2015-03-18T08:18:37 < jpa-> it's been the same for decades already: people can't really tell the supposed difference in audio quality in high-quality stuff, they just want to pay more to feel better

2015-03-18T09:39:36 < PeterM> PaulFester what packaging is the cell you want to weatherproof? Pouch, cylinder, block, coin, strip?
2015-03-18T09:41:42 < PaulFertser> PeterM: I don't know yet, it's my buddy innovating something, not me.

2015-03-18T09:44:32 < PeterM> if its a pouch cell and you are using long time per cycle you probably want some type of clamping/compession on the cell. if its a cylinder cell, adhesive lined heatsink is pretty good
2015-03-18T09:45:38 < PaulFertser> PeterM: can you please clarify, why might I want clamping/compression for a pouch cell?
2015-03-18T09:46:07 < ReadError> PaulFertser look at the 18650s?
2015-03-18T09:46:12 < ReadError> they are pretty high capacity
2015-03-18T09:46:18 < PaulFertser> ReadError: seen them :)))
2015-03-18T09:46:22 < PaulFertser> Who didn't?
2015-03-18T09:48:05 < PeterM> PaulFester heating and cooling cycles can cause the internal layers to slightly seperate causing slight outgassing during charge/discharge cycles, clamping the cells prevents this to a degree
2015-03-18T09:48:55 < PaulFertser> PeterM: can't that harm the cell? If I understood him right, zyp says they allow some space for that process instead of clamping.
2015-03-18T09:49:00 < dongs> zyp: apparently thats xbone or osmething, there's no 3rd party shits
2015-03-18T09:49:29 < zyp> oh, idk
2015-03-18T09:50:24 < PeterM> PaulFertser, it can if yu clamp too tight or do uneven pressure, but unclamped cells just tnd to baloon - once they start to expand its a bit fo a runaway process
2015-03-18T09:50:27 < zyp> I guess that shit isn't HID, but that other MS game controller profile
2015-03-18T09:51:07 < zyp> mostly just a descriptor change though
2015-03-18T09:51:13 < PaulFertser> PeterM: aren't the cells in the consumer equipment unclamped? Or am I missing something?
2015-03-18T09:51:28 < PeterM> PaulFester: example?
2015-03-18T09:52:04 < jpa-> PaulFertser: usually they are quite tightly in the enclosure

2015-03-18T09:52:44 < jpa-> but i do not know if the clamping is good or bad
2015-03-18T09:52:49 < PeterM> often they are clamped by the housing of the device itself if they are a pouch type cell
2015-03-18T09:53:09 < dongs> zyp, maybe thre's a new nichemarket for you

2015-03-18T09:53:57 < zyp> xbox wireless isn't BT as far as I know
2015-03-18T09:54:21 < dongs> > Wacky-slightly-edited Bluetooth hid.
2015-03-18T09:54:22 < dongs> > like the PS3/PS4 does
2015-03-18T09:54:26 < dongs> ^ according to my propal
2015-03-18T09:54:34 < zyp> huh
2015-03-18T09:54:41 < dongs> xbox one
2015-03-18T09:54:42 < PeterM> although that is LiFePO4, physical construction of the cells is incrediubly similar
2015-03-18T09:55:02 < zyp> from what I've heard, using xbox controllers on pc requires a special usb dongle
2015-03-18T09:55:17 < zyp> while PS3/wii can be used through plain BT
2015-03-18T09:55:47 < dongs> The new proprietary protocol.to be clear, it's not WiFi nor Bluetooth, which Alam said was too slow for their needs.should reduce controller-to-console latency by 20% compared to the old 360 connection. How fast? Alam says that the time from button press on an Xbox One controller to the console receiving the signal should be 9 milliseconds.
2015-03-18T09:55:51 < PeterM> PS3 requires special driver, xbox requires  dong(le) + special driver
2015-03-18T09:55:52 < dongs> oh hm
2015-03-18T09:55:52 < dongs> maybe it is some proprietary shit

2015-03-18T14:58:50 < englishman> Getty: apple has like 10x as much cash as facebook.
2015-03-18T14:58:56 < englishman> they really have no idea what to do with it
2015-03-18T14:59:14 < englishman> they can buy whatever they want, but theyve pretty much just been paying excessive dividends
2015-03-18T14:59:34 < Getty> englishman: yeah still the amount of companies they actually can buy is very low, there is literally no option to buy "robust and solid" companies
2015-03-18T15:00:03 < englishman> well im not executive
2015-03-18T15:00:10 < englishman> but you dont make money buying established companies
2015-03-18T15:00:29 < Getty> the problem is the missing synergy, apple is not having this concept at all
2015-03-18T15:00:31 < Getty> they just consume
2015-03-18T15:00:36 < englishman> yes
2015-03-18T15:00:40 < englishman> good for shareholders
2015-03-18T15:01:00 < Getty> yeah but if you buy a "good product" in that kind of situation, you are just "killing" the good name and integrate the product, which would be a shareholder lost
2015-03-18T15:01:06 < Getty> thats why apple is limited in what they can buy
2015-03-18T15:01:16 < Getty> beats is like the prime reference example of what they can buy ;)
2015-03-18T15:01:25 < Getty> next on my list would be red bull ;-)
2015-03-18T15:12:06 < jpa-> englishman: what makes the dividends excessive?
2015-03-18T15:12:35 < englishman> i guess cuz under steve jobs there never were any
2015-03-18T15:13:07 < Getty> it is actually now interesting to see if the mentality is apple or if it was really just jobs
2015-03-18T15:13:29 < englishman> and after the 7:1 split the dividend amount didnt split...
2015-03-18T15:13:31 < Getty> jobs did everything to give apple exclusive positions on every market, i dont know if apple still tries todo that "at all cost"
2015-03-18T15:14:03 < Getty> you should read up the revealed emails between jobs and the book publisher ;)
2015-03-18T15:14:27 < englishman> or maybe it did i forget
2015-03-18T15:27:57 < jpa-> Getty: what did jobs do to "give apple exclusive positions"?
2015-03-18T15:39:43 < Getty> jpa-: find those emails, that is the best about it
2015-03-18T15:40:06 < Getty> jpa-: to make it short: he really blackmailed the shit out of them all "you join our concept exclusive or you dont come in at all"
2015-03-18T15:40:22 < Getty> and the content owners felt pushed
2015-03-18T15:40:46 < jpa-> ah, haven't seen; business as usual, like how microsoft (allegedly) gets its OS on every PC sold
2015-03-18T15:41:06 < Getty> microsoft is somehow a sheep against apple tactics
2015-03-18T15:41:15 < jpa-> so i guess you are talking about itunes, doesn't count as "every market" to me
2015-03-18T15:41:42 < Getty> yeah well, it is like all media, and every market they are in, yes :)
2015-03-18T15:42:05 < Getty> i mean that also includes the cell phone market, they enforce rules on the carriers which are not normal
2015-03-18T15:42:32 < Getty> and the carriers go with it, ensure this way apples power and apple gets their solid position
2015-03-18T15:43:27 < Getty> in the end, all history of apple is not based on "its a good product, thats why it has its position" its always based on brutal deals that enforce market positions
2015-03-18T15:46:49 < jpa-> hmm, what kind of brutal deals did they do to market Apple I?
2015-03-18T15:47:58 < Getty> well...... if you check it out detailed, you will see that even there steve jobs was not correct and told different numbers to different people ;)
2015-03-18T15:48:24 < Getty> but that part is not actually what i meant, the start of apple was still pretty normal, even tho, jobs already there was... straightforward
2015-03-18T15:48:32 < Getty> didnt you watched the movie??? ;)
2015-03-18T15:48:44 < Getty> even tho the movie was somehow horrible extreme
2015-03-18T15:49:13 < jpa-> no, i actually don't give a shit about this stuff
2015-03-18T15:49:32 < jpa-> i just saw someone talking stupid on internet and engaged
2015-03-18T15:49:37 < Getty> hehehe you should watch it :) interesting history
2015-03-18T15:49:45 < Getty> that will explain what i said, and you will understand
2015-03-18T15:50:05 < Getty> i mean there are many documentations about apple, see them all and you know what has happened

2015-03-18T18:52:46 < trepidaciousMBR> kakeman: Yup we've had that issue - board hangs => either PHY is not giving us a clock, or maybe the RTC crystal is not working :)
2015-03-18T18:53:12 < kakeman> what device?
2015-03-18T18:53:14 < trepidaciousMBR> kakeman: Doesn't it depend on your startup code though? I don't hink you HAVE to wait for the phy clock
2015-03-18T18:53:18 < trepidaciousMBR> STM32F437
2015-03-18T18:54:00 < kakeman> ok even rtc can cause device to hang :o
2015-03-18T18:54:04 < kakeman> mad
2015-03-18T18:54:51 < trepidaciousMBR> kakeman: I guess they are fairly basic things, so if they break you probably can't really do a lot anyway, but it is kind of annoying
2015-03-18T18:55:20 < trepidaciousMBR> But I think if you look at the startup code, you can probably give up on waiting for either of those clocks. We use ChibiOS, which will just wait forever.
2015-03-18T19:04:46 < kakeman> could rmii clock be used as core clock=
2015-03-18T19:05:09 < kakeman> .. external clock source
2015-03-18T19:05:23 < kakeman> it would explain
2015-03-18T19:06:04 < kakeman> or is it actually used to make system clock that is in sync to ethernet phy :o

2015-03-18T19:11:24 < kakeman> is there relationship between main clock and rmii refernce clock?
2015-03-18T19:28:03 < trepidaciousMBR> kakeman: Ah right
2015-03-18T19:28:44 < trepidaciousMBR> kakeman: AFAIK the RMII clock is independent of other clocks, it's generated by the PHY, it needs to be (I think) exactly 50 or 100MHz, something like that
2015-03-18T19:29:07 < kakeman> 50ppm or so
2015-03-18T19:30:03 < trepidaciousMBR> You can get odd effects from a small amount of jitter, for example if using MCO with PLL on the MCU

2015-03-18T19:31:03 < trepidaciousMBR> I can't actually remember what setup we use, you can do something quite neat, I think it's a 25MHz clock for the MCU, passed straight through to MCO without PLL for a PHY that accepts a 25MHz clock, then it passes backa  50MHz clock for comms... that could be completely wrong ;)
2015-03-18T19:32:15 < trepidaciousMBR> Might be this one :) http://media.digikey.com/pdf/Data%20Sheets/SMSC/LAN8720.pdf

2015-03-18T19:35:35 < Steffanx> reichelt maybe?

2015-03-18T19:36:24 < Steffanx> oh they too, for expensive.
2015-03-18T19:38:06 < Steffanx> need more Fleck?
2015-03-18T19:40:13 < Fleck> Only farnell has the part I need, those two don't
2015-03-18T19:41:48 < Fleck> And I usually leave farnell as last option :p

2015-03-18T19:42:33 < Steffanx> Why? They tend not to be the cheapest, but neither are the alternatives in the EU
2015-03-18T19:43:23 < Fleck> I usually order from tme.eu
2015-03-18T19:44:06 < kakeman> lpc board has own ocillator for
2015-03-18T19:44:11 < kakeman> lan8720
2015-03-18T19:45:30 < Steffanx> oh there is RS too, but RS is weird.
2015-03-18T19:45:48 < edmoore> i do farnell for everything
2015-03-18T19:46:00 < edmoore> and RS for everything farnell doesn't have, usually more in hardware and industrial control
2015-03-18T19:46:08 < edmoore> but i use both a lot
2015-03-18T19:49:02 < Steffanx> all company stuff i guess? RS and farnell don't like non-company customers.
2015-03-18T19:49:12 < kakeman> i see stm32 has more dope ethernet than lpc in same range
2015-03-18T19:49:12 < Steffanx> At least here in dutchland.
2015-03-18T19:49:22 < kakeman> by features
2015-03-18T19:50:20 < Fleck> Thanks
2015-03-18T19:50:23 < BrainDamage> i've bought few times both as private and company from RS and didn't have troubles except for prices
2015-03-18T19:51:40 < Steffanx> here farnell requires you to order by email and over 50eur. , but over 50eur is easy
2015-03-18T19:52:04 < Steffanx> oh actually they tell you to email, but then they tell you to enter so code and order using hte website.
2015-03-18T19:52:25 < Steffanx> and the accept a screenshot of your payment as proof you paid <3
2015-03-18T19:52:35 < Steffanx> *they
2015-03-18T19:53:44 < Steffanx> perhaps that last part only applies to the dutch farnell.

2015-03-18T21:44:43 < edmoore> and normally 30+% discounts for large orders (>£1000?)
2015-03-18T21:44:47 < qyx_> they are nice to me too
2015-03-18T21:44:59 < qyx_> and i am not even a company

2015-03-18T21:46:26 < edmoore> for a mars-sample-return mission study
2015-03-18T21:46:43 < edmoore> in that case you just split the CO2 atmosphere into CO + O2
2015-03-18T21:47:16 < edmoore> we looked at some more exotic and mastier things that were also synthesiable (e.g. cyanogens) but the CO+O2 had pleasing behaviour
2015-03-18T21:48:11 < qyx_> i like that blueish fire
2015-03-18T21:48:45 < edmoore> yeah it was pretty

2015-03-18T21:52:13 < edmoore> whereas the mars propellants was a bit of publically funded fun
2015-03-18T21:52:25 < edmoore> it's a shame as some of the hardware is quite pleasing to the eye, i think
2015-03-18T21:52:39 < edmoore> i've always been attracted to things that blend a lot of mechanics and electronic together

2015-03-19T05:36:43 < dongs> lol simulating
2015-03-19T05:36:53 < dongs> thats why just get someone else to do that shit
2015-03-19T05:37:09 < upgrdman> im that someone else ;)
2015-03-19T05:37:21 < upgrdman> im officially a pro troll in training now
2015-03-19T05:37:29 < Getty> you wish
2015-03-19T05:37:42 < upgrdman> i am. landed a job as an EE intern
2015-03-19T05:37:47 < dongs> lol
2015-03-19T05:37:55 < dongs> nice
2015-03-19T05:37:58 < dongs> whats your job description
2015-03-19T05:38:28 < upgrdman> help with the development, testing and debugging of medial electronic equipment
2015-03-19T05:38:37 < upgrdman> and since im an intern, probably lots of bitch work too
2015-03-19T05:38:49 < dongs> ""rework these 0402 parts asap""
2015-03-19T05:39:04 < upgrdman> actually their flagship model is all PTH. only ass design
2015-03-19T05:39:08 < dongs> you better not tlel them you prefer opensores eda tools
2015-03-19T05:39:13 < upgrdman> they're redoing it though. part of why i was hired
2015-03-19T05:39:23 < upgrdman> they have a 4-layer, smd prototype
2015-03-19T05:39:49 < upgrdman> dongs, they use altium. that's part of why im learning altium now.
2015-03-19T05:40:19 < dongs> R2COM is a perm intern
2015-03-19T05:40:42 < upgrdman> ya, they started by throwing a copy of IEC 60601 at me.
2015-03-19T05:41:00 < upgrdman> so boring, but not surprised considering my position
2015-03-19T05:41:44 < upgrdman> ya. but im at the bottom of the totem pole now.
2015-03-19T05:42:09 < upgrdman> but im not complaining.
2015-03-19T05:42:22 < GargantuaSauce> not like you'll be there long
2015-03-19T05:42:25 < upgrdman> i LOVE that they're close to me. i live 2 miles from the office.
2015-03-19T05:42:42 < dongs> finally someone in the channel has a real job
2015-03-19T05:42:53 < GargantuaSauce> we are collectively validated by this
2015-03-19T05:43:08 < dongs> dont fuck it up, so we can hear stories of continuous fuckups
2015-03-19T05:43:13 < upgrdman> ya. not sure how they handle interns. they indicated that full time positions would be a possibiliy, but dunno if they were being honest.
2015-03-19T05:43:51 < upgrdman> they seems like nice people tho. no one appeared to be an ass hole, or dead weight, etc.
2015-03-19T05:44:50 < upgrdman> R2COM, you've seen my boards. no PTH, except for 0.1" header that a "make" smd anyway.
2015-03-19T05:45:20 < upgrdman> :)
2015-03-19T05:45:33 < upgrdman> if they pay for it, i'll etch whatever the fuck they want
2015-03-19T05:45:56 < upgrdman> and if they want to made for made-in-usa fast fab'ing, i'd do that too
2015-03-19T05:46:04 < upgrdman> 8L all-the-things
2015-03-19T05:47:14 < upgrdman> that balancing robot i made was a big conversation piece during my interview. i guess i impressed their senior engineer, considering that im finished a CS degree instead of CE/EE
2015-03-19T05:47:40 < dongs> chief trolling officer
2015-03-19T05:47:50 < upgrdman> "you know more than almost all of the EE students i've talked to"

2015-03-19T05:48:12 < upgrdman> not the engineering majors.

2015-03-19T12:52:44 < dongs> jpa, if the clock is not there, waht are you resetting
2015-03-19T13:02:58 < jpa-> the peripherals keep their state even if clock is disabled, and disabling clocks when peripheral is not in use saves some power
2015-03-19T13:03:22 < jpa-> but i ended up doing sysreset and jumping from main() to elsewhere.. too much hassle trying to reset everything manually

2015-03-19T13:06:57 < dongs> that might be a neat trick
2015-03-19T13:07:06 < dongs> so if you kill clock, it keeps state?
2015-03-19T13:09:02 < edmoore> this bit of equipment uses a 3-pin XLR for power
2015-03-19T13:09:12 < edmoore> there should be legal consequences for such bad design choices
2015-03-19T13:11:10 < Steffanx> that's just a bad as using a mono jack for power edmoore imho
2015-03-19T13:11:31 < Steffanx> especially when the male connector is terrible cheap and bad
2015-03-19T13:11:39 < Steffanx> *female
2015-03-19T13:12:32 < jpa-> dongs: yeah, AFAIK

2015-03-19T13:17:01 < edmoore> Steffanx, sure
2015-03-19T13:17:12 < edmoore> and especially when 4-pin xlr is the standard in the broadcast industry
2015-03-19T13:17:17 < edmoore> and this is a bit of video switching kit
2015-03-19T13:18:42 < jpa-> Steffanx: nope, this clock toggling stuff is done by someone else
2015-03-19T13:19:04 < jpa-> i'm not optimizing power now so haven't measured if it does anything useful
2015-03-19T13:19:35 < jpa-> now, on a separate note - wtf is going on with these abstraction layers
2015-03-19T13:19:58 < jpa-> there is 121 lines of "code" and 2 files - and all it does is call a single function

2015-03-19T13:37:47 < jpa-> meh, i'll just rewrite this shit
2015-03-19T13:38:51 < dongs> use libopenstm32aids
2015-03-19T13:39:49 < edmoore> is it just me or....
2015-03-19T13:39:59 < edmoore> is anyone else really happy just doing a cortex m0 in assembly?
2015-03-19T13:40:06 < dongs> ... no
2015-03-19T13:40:08 < dongs> just you.
2015-03-19T13:40:11 < edmoore> i've been thinking this after a few days of doing battle with chibios
2015-03-19T13:40:19 < dongs> thats cuz youre using chibios.
2015-03-19T13:40:26 < edmoore> and 9 levels of indirection per peripheral setup
2015-03-19T13:41:02 < jpa-> if you don't want the abstraction, do not use it
2015-03-19T13:41:13 < jpa-> but if you don't want premade register definitions, i think you are crazy
2015-03-19T13:41:30 < jpa-> and if you want assembler instead of C, i think you don't want to get stuff done
2015-03-19T13:41:50 < edmoore> yes that certainly happens :)
2015-03-19T13:46:10 < edmoore> i get little attacks of wanting to rewrite everything from scratch in a clean, pure, and above all invented-here way

2015-03-19T14:33:51 < Laurenceb> atm it "works"
2015-03-19T14:34:07 < Laurenceb> im trying to fix the USB, but i need the scripting to work
2015-03-19T14:35:29 < dongs> i duno. all i know s newer firmware blacklisted more SD cards
2015-03-19T14:35:34 < dongs> as they dont deem them "fast enough"
2015-03-19T14:35:39 < dongs> so i never bothered upgrading mine
2015-03-19T14:35:40 < Laurenceb> arg
2015-03-19T14:36:00 < Laurenceb> well I have a decent SanDisk card
2015-03-19T14:36:03 < Laurenceb> should be ok
2015-03-19T14:36:24 < Laurenceb> im tempted to try powering it via the 30pin connector
2015-03-19T14:36:39 < dongs> why cant you
2015-03-19T14:36:43 < Laurenceb> atm I have 3 batteries on the balloon payload, pretty stupid
2015-03-19T14:36:50 < Laurenceb> dunno... havent tried yet
2015-03-19T14:37:09 < Laurenceb> do you know why AfroESC is using 45mA ?
2015-03-19T14:37:17 < Laurenceb> is it the failmega?

2015-03-19T14:39:11 < dongs> 45mA idle?
2015-03-19T14:39:15 < Laurenceb> yes
2015-03-19T14:39:27 < Laurenceb> is there a schematic available?
2015-03-19T14:39:27 < dongs> its failmega + ~15mA led + just idle current of other crap
2015-03-19T14:39:34 < Laurenceb> hmm
2015-03-19T14:39:36 < dongs> edit firmware and kill led
2015-03-19T14:39:40 < dongs> the standby green one
2015-03-19T14:40:12 < qyx_> 15mA for a led is quite much
2015-03-19T14:40:28 < Laurenceb> yeah, its not even on
2015-03-19T14:40:50 < Laurenceb> its not the LED

2015-03-19T14:42:50 < Laurenceb> how much current does that take?
2015-03-19T14:43:09 < dongs> thermistor is vcc -> 3.3K > 10K ntc > gnd

2015-03-19T14:43:18 < Laurenceb> ok
2015-03-19T14:43:23 < dongs> voltage monitor is 18k/3.3k divider

2015-03-19T14:54:05 < Laurenceb> thats not the issue
2015-03-19T14:54:17 < dongs> does that acutally work/
2015-03-19T14:54:24 < dongs> i forgot if we set internal atmega shit to nopull
2015-03-19T14:54:28 < dongs> so you can use lower voltage levels
2015-03-19T14:54:31 < Laurenceb> i disabled that
2015-03-19T14:54:33 < dongs> ah ok
2015-03-19T14:54:53 < Laurenceb> is the i2c interrupt based?
2015-03-19T14:56:45 < Laurenceb> guess i should read the firmware lol
2015-03-19T14:56:48 < Laurenceb> asm :-S
2015-03-19T14:57:09 < Laurenceb> 78l05 isnt 500mA
2015-03-19T14:57:19 < Laurenceb> but spec sheet says 500mA "BEC"
2015-03-19T15:02:35 < dongs> wrong
2015-03-19T15:02:39 < dongs> ther's a regular 7805
2015-03-19T15:02:44 < dongs> in SOT223 or someshit
2015-03-19T15:02:44 < ReadError> 2 7805
2015-03-19T15:02:47 < dongs> zano style
2015-03-19T15:02:51 < Laurenceb> oh
2015-03-19T15:02:52 < ReadError> or 2 ldo right?
2015-03-19T15:03:01 < dongs> 78l05 is only for mcu
2015-03-19T15:03:06 < Laurenceb> ah
2015-03-19T15:03:10 < dongs> you can probly desolder the 2 7805s
2015-03-19T15:03:17 < dongs> i wonder how their Iq is
2015-03-19T15:03:22 < Laurenceb> wait there are 3 total?
2015-03-19T15:03:25 < dongs> yes
2015-03-19T15:03:30 < Laurenceb> sheeet
2015-03-19T15:03:39 < Laurenceb> thats whats using the current
2015-03-19T15:03:52 < dongs> haha
2015-03-19T15:03:54 < dongs> 6.5mA
2015-03-19T15:03:55 < Laurenceb> which manufacturer?
2015-03-19T15:03:55 < dongs> per 7805
2015-03-19T15:03:58 < dongs> accordint to TI
2015-03-19T15:04:03 < dongs> Laurenceb: i'd guess UTC
2015-03-19T15:04:04 < dongs> chinabrand
2015-03-19T15:04:13 < Laurenceb> prob higher then
2015-03-19T15:04:13 < dongs> http://www.unisonic.com.tw/datasheet/LM78XX.pdf
2015-03-19T15:04:23 < dongs> 8mA
2015-03-19T15:04:28 < Laurenceb> rofl
2015-03-19T15:04:43 < Laurenceb> ok this makes sense then
2015-03-19T15:05:06 < Laurenceb> 18mA AVR, ~24mA regulators then a few for the pot dividers

2015-03-19T15:28:29 < Laurenceb> dongs: do you know anything about the avr firmware?
2015-03-19T15:28:41 < Laurenceb> is there a wait routine somewhere that busy loops?
2015-03-19T15:29:14 < dongs> with i2c, im not really sure
2015-03-19T15:30:01 < Laurenceb> oh it seems to use timer1 overflow
2015-03-19T15:30:05 < Laurenceb> seems sensible
2015-03-19T15:30:31 < Laurenceb> i should just be able to replace all wait calls with an added idle state entry
2015-03-19T15:39:45 < Laurenceb> looks like i should eb able to knock it down to 9mA by removing regs and
2015-03-19T15:40:02 < Laurenceb> inserting idle state at		rjmp	i_rc_puls2 at line 2856

2015-03-19T18:08:28 < Laurenceb> Simon--: hi
2015-03-19T18:08:50 < Laurenceb> im trying to make afro esc save power
2015-03-19T18:09:00 < Steffanx> replace it with a stm32l0
2015-03-19T18:09:04 < Simon--> Laurenceb: ok
2015-03-19T18:09:05 < Laurenceb> lol
2015-03-19T18:09:20 < Laurenceb> im going to rip off the 7805 reg
2015-03-19T18:09:21 < Simon--> I tinhk most of the problem will probably be through the high-side NPNs
2015-03-19T18:09:34 < Laurenceb> but it looks like i can save another 11mA using idle mode
2015-03-19T18:09:36 < Laurenceb> ah
2015-03-19T18:09:49 < Laurenceb> this is afro nfet
2015-03-19T18:09:55 < Simon--> could probably make it turn them on if idle for a while though
2015-03-19T18:09:59 < Simon--> yeah
2015-03-19T18:10:07 < Laurenceb> hmm
2015-03-19T18:10:18 < Laurenceb> i tried to work out a current budget
2015-03-19T18:10:19 < Steffanx> Laurenceb, maybe you can cheat and call a avr-libc sleepmode functions from the assembly code
2015-03-19T18:10:21 < Simon--> "off" state sinks quite a bit of current since there's only single npns per high side phase
2015-03-19T18:10:25 < Steffanx> -s
2015-03-19T18:10:30 < Laurenceb> oh
2015-03-19T18:10:38 < Laurenceb> i get 47mA at 12v
2015-03-19T18:10:40 < Simon--> what's the application?
2015-03-19T18:10:47 < Laurenceb> its a balloon payload
2015-03-19T18:10:59 < Laurenceb> i need to run off a 350mAh cell for low mass
2015-03-19T18:11:09 < Laurenceb> and it might be connected for ~5hours total
2015-03-19T18:11:22 < Laurenceb> ideally i need <20mA current draw
2015-03-19T18:11:27 < Simon--> so you need 12V support and what current for operation?
2015-03-19T18:11:40 < Laurenceb> as much as possible during spinup
2015-03-19T18:11:50 < Laurenceb> pref >30A with little dropout
2015-03-19T18:11:59 < Laurenceb> so an external fet looks tricky
2015-03-19T18:12:42 < Laurenceb> i tried to calculate the current draw, got 20mA for the AVR, then 16mA for the 2x 7805 vregs and 2mA for the pot dividers
2015-03-19T18:12:55 < Laurenceb> so <9mA for other stuff
2015-03-19T18:13:19 < Laurenceb> im going to remove the BEC vreg and attempt some sleep mode
2015-03-19T18:13:38 < Laurenceb> do you think i could change the gpio idle states to save some current?
2015-03-19T18:14:36 < Simon--> yah. can you use a 40A or maybe one of the newer escs with drivers, maybe? that would probably save the most
2015-03-19T18:14:47 < Simon--> though you're probably trying to save weight, too..
2015-03-19T18:15:00 < Laurenceb> yeah
2015-03-19T18:15:02 < Simon--> would it hurt to have braking enabled when idle?
2015-03-19T18:15:12 < Laurenceb> this one is more than good enough
2015-03-19T18:15:22 < Laurenceb> accept for the current
2015-03-19T18:15:26 < Laurenceb> no that makes no difference
2015-03-19T18:15:31 < Simon--> I'd probably change the brake to be high side instead of low side, then jam a sleep in the idle loop
2015-03-19T18:15:39 < Laurenceb> i just need ~100rpm to ~12krpm in <300ms
2015-03-19T18:15:45 < Laurenceb> and for it to work once :P
2015-03-19T18:15:55 < Simon--> ~100rpm means "started"?
2015-03-19T18:15:57 < Laurenceb> ok, where is the idle loop?
2015-03-19T18:15:58 < Laurenceb> yes
2015-03-19T18:16:08 < Laurenceb> line 2856?
2015-03-19T18:16:15 < Laurenceb> rjmp	i_rc_puls2
2015-03-19T18:16:34 < Simon--> which tree you looking at
2015-03-19T18:16:52 < Laurenceb> erm my custom one lol
2015-03-19T18:16:53 < Laurenceb> 1 sec
2015-03-19T18:17:06 < Simon--> that's the arming loop which waits for input from any input
2015-03-19T18:17:36 < Simon--> depending on how you feed it, you could do it there
2015-03-19T18:18:00 < Laurenceb> http://pastebin.com/nAB6mMcs
2015-03-19T18:18:12 < Laurenceb> its running over i2c
2015-03-19T18:18:37 < Laurenceb> i poll the i2c regularly to get voltage and temperature, even when motor isnt running
2015-03-19T18:18:46 < Simon--> ahh
2015-03-19T18:19:15 < Laurenceb> this is a branch from balrog-kuh on github, with simple i2c mode
2015-03-19T18:19:34 < Simon--> ok
2015-03-19T18:19:45 < Simon--> I need to still look at merging that
2015-03-19T18:20:06 < Laurenceb> his ADC code can cause missed commutation at high rpm
2015-03-19T18:20:20 < Simon--> maybe for your application you should kill rc_timeout or the entire arming part to not introduce more problems?
2015-03-19T18:20:24 < Simon--> yeah, I suspected it would
2015-03-19T18:20:26 < Laurenceb> i disabled it at high rpm as a simple fix
2015-03-19T18:20:30 < Simon--> ok
2015-03-19T18:20:56 < Laurenceb> not a major issue
2015-03-19T18:21:05 < Laurenceb> in fact, i was running motor without a prop
2015-03-19T18:21:13 < Laurenceb> so the added moment of inertia may fix it
2015-03-19T18:21:51 < Simon--> so err, I've only looked at sleep stuff on stm32f3 :) I think on avr, though, the default for sleep is like WFI
2015-03-19T18:21:58 < Simon--> which should work for your case
2015-03-19T18:21:59 < Laurenceb> yes
2015-03-19T18:22:15 < Simon--> then the only other change you might want to do is just turn on all high side fets while waiting
2015-03-19T18:22:37 < Simon--> that should stop the conduction through the npns, though..let me check schematic
2015-03-19T18:23:12 < qyx_> wht
2015-03-19T18:23:43 < qyx_> when you turn them on, the gate is pulled low through the npns
2015-03-19T18:23:57 < qyx_> so a current flows through the gate pullup
2015-03-19T18:24:04 < qyx_> if you keep them off, no current flows
2015-03-19T18:24:10 < Simon--> yah sorry, it's "on" meaning low in this case
2015-03-19T18:24:33 < Simon--> it's inverted because of this setup :)
2015-03-19T18:25:28 < Simon--> to do it safely, though, you'll rpobably need a delay before trying to drive it, or the gate caps will discharge and may be half-charged while trying to start the motor
2015-03-19T18:29:19 < Laurenceb> im confused
2015-03-19T18:29:38 < Laurenceb> i could only be seeing 3mA max per channel
2015-03-19T18:29:42 < Laurenceb> is that feasible?
2015-03-19T18:29:48 < Laurenceb>  (of leakage)
2015-03-19T18:30:33 < Simon--> leakage per phase when high side is off?
2015-03-19T18:30:39 < Laurenceb> doh
2015-03-19T18:30:40 < Simon--> (gate on)?
2015-03-19T18:30:51 < Laurenceb> i should just get my scope out and probe this thing
2015-03-19T18:30:52 < Simon--> er, npn base conducting
2015-03-19T18:30:53 < Simon--> hehe
2015-03-19T18:30:54 < Simon--> ok
2015-03-19T18:31:49 < Simon--> it's batt->diode->2k->NPN(collector-emitter)->gnd per phase (and the loss of 5V gpio via 4.7k to base)
2015-03-19T18:31:53 < Laurenceb> all outputs are 0v
2015-03-19T18:32:04 < Laurenceb> apart from avery 16 seconds or so
2015-03-19T18:32:12 < Laurenceb> the beep
2015-03-19T18:32:21 < Simon--> set BEACON to 0 to kill that
2015-03-19T18:32:45 < Laurenceb> well thats helpful to let me know its alive
2015-03-19T18:32:51 < Laurenceb> and quite low current draw
2015-03-19T18:32:53 < Laurenceb> http://i.stack.imgur.com/S1jym.png
2015-03-19T18:32:56 < Laurenceb> ^like that?
2015-03-19T18:33:28 < Simon--> yeah
2015-03-19T18:33:46 < Laurenceb> thats 16mA
2015-03-19T18:33:58 < Laurenceb> brb

2015-03-19T18:38:54 < Laurenceb> jcoxon has done worse...
2015-03-19T18:39:30 < edmoore> ?
2015-03-19T18:41:36 < Laurenceb> his exploding hand removing cutdown
2015-03-19T18:42:17 < edmoore> i don't think his hand exploded
2015-03-19T18:44:14 < Laurenceb> not quite
2015-03-19T18:44:17 < Laurenceb> ok im back
2015-03-19T18:44:39 < Laurenceb> i see now, if those transistors are on its ~16mA
2015-03-19T18:45:17 < Laurenceb> hmm
2015-03-19T18:45:39 < Laurenceb> yeah current budget matches exactly, its just dongs was wrong about the number of vregs
2015-03-19T18:45:44 < Laurenceb> there are only 2
2015-03-19T18:46:07 < Laurenceb> Simon--: so if i enable break it will turn the npn transistors off?
2015-03-19T18:56:41  * Laurenceb tries to understand brake code and fries his brain
2015-03-19T18:56:43 < Simon--> no, unfortunately, brake is typically on low side because it's "easier" to do it there
2015-03-19T18:56:47 < Laurenceb> yeah
2015-03-19T18:56:56 < Simon--> brake is optionally "soft start"/pulsed, but ignore that
2015-03-19T18:57:04 < Laurenceb> ok
2015-03-19T18:57:40 < Simon--> the problem with high side drive with N-ch FETs (in pretty much all cases) is that the bootstrap cap to drive them will eventually discharge, since the gate has to be held above bat voltage as long as they are on
2015-03-19T18:57:43 < Simon--> so typically, they can't stay on forever
2015-03-19T18:58:12 < Simon--> with that configuration, humidity/leakage plays a big part in how long that cap stays charged, or how long holding them on actually keeps them on
2015-03-19T18:58:34 < Simon--> this is why on those escs, pulling the power makes the motor hard to turn for "a while" (sometimes minutes)
2015-03-19T18:58:51 < Laurenceb> ah
2015-03-19T18:58:58 < Simon--> with all of the high or low fets on at once, it just shorts all of the motor wires together
2015-03-19T18:59:41 < Simon--> now, if the transistor is turned back on again, the cap starts charging back up, but you just have to be careful not to start driving current through the fets while the cap is near fet on/off threshold voltage
2015-03-19T18:59:42 < Simon--> make sense?
2015-03-19T18:59:54 < Laurenceb> yes i think so
2015-03-19T19:01:04 < Laurenceb> could i just change the idle state gpio config?
2015-03-19T19:01:21 < Laurenceb> so lower fet gates are low
2015-03-19T19:01:23 < Simon--> so we cold just turn on the high side indefinitely to save power and make sure there's enough delay for it to charge..it's only 4.7uF so there's probably enough delay already
2015-03-19T19:01:31 < Laurenceb> as are high side drive lines
2015-03-19T19:01:45 < Simon--> "turn on" -> gpio low, npn off
2015-03-19T19:01:50 < Laurenceb> yes
2015-03-19T19:02:10 < Simon--> if you change the .inc file where the idle state is defined, the rest of the code starts driving it inverted.. which means bang
2015-03-19T19:02:25 < Laurenceb> yeah, so i need to change the asm?
2015-03-19T19:02:44 < qyx_> wat, there are high side drivers?
2015-03-19T19:02:51 < qyx_> ahy are you talking about npns then
2015-03-19T19:03:03 < Laurenceb> with no brake, idle low gate state is 0v ?
2015-03-19T19:03:15 < Laurenceb> qyx_: http://i.stack.imgur.com/S1jym.png
2015-03-19T19:03:18 < Simon--> yah. is disarmed really how you want it to idle? if you want to start the motor really quickly, do you need to react quickly to something?
2015-03-19T19:03:36 < Simon--> qyx_: no drivers here. if there were, idle current would be much better
2015-03-19T19:03:46 < Laurenceb> i only want to ramp quickly
2015-03-19T19:03:52 < Laurenceb> i dont care about any delay
2015-03-19T19:03:57 < qyx_> what the hell is that
2015-03-19T19:03:59 < qyx_> much innovation
2015-03-19T19:04:16 < Simon--> it's pretty typical for cheap escs
2015-03-19T19:05:33 < qyx_> then i was wrong of course because i assumed p-mosfets on the high side
2015-03-19T19:05:49 < Simon--> Laurenceb: ok, fine, just add some crap aroud that loop and sleep in the middle, I guess..
2015-03-19T19:06:02 < Simon--> sorry, no all_pFETs_on macro because it's usually not what you want
2015-03-19T19:06:04 < Laurenceb> the line 2856 loop?
2015-03-19T19:06:49 < Simon--> Laurenceb: before 2837
2015-03-19T19:07:22 < Simon--> its spits on wdr to reset the watchdog while waiting
2015-03-19T19:07:26 < Simon--> err, spins
2015-03-19T19:07:30 < Laurenceb> ok
2015-03-19T19:07:45 < Laurenceb> will it still get to that point after the motor has been spun once?
2015-03-19T19:07:58 < Simon--> if you stop sending stuff for a while, it should disarm and go back there
2015-03-19T19:08:08 < Laurenceb> ah ok, perfect
2015-03-19T19:08:31 < Simon--> (default "a while" is 128ms)
2015-03-19T19:08:45 < Simon--> err
2015-03-19T19:08:59 < Simon--> that's power cut. disarm is like 2s
2015-03-19T19:09:40 < Laurenceb> no problem
2015-03-19T19:09:47 < Laurenceb> im thinking about like 20hours :P
2015-03-19T19:10:02 < Laurenceb> if recovery takes a while
2015-03-19T19:11:04 < Simon--> ah. if you want, you can change beep volume (current) by tweaking numbers in beep routines

2015-03-19T20:16:42 < Laurenceb> SPMCR?
2015-03-19T20:17:17 < Laurenceb> no
2015-03-19T20:17:18 < Laurenceb> argggg
2015-03-19T20:17:40 < Laurenceb> this is why cortex was standardised
2015-03-19T20:18:26 < Steffanx> and still you can't really use code used for some stm32f1 on a f4.
2015-03-19T20:20:05 < Simon--> Laurenceb: you looking for sleep mode or something?
2015-03-19T20:20:13 < Simon--> it's in MCUCR on that cpu
2015-03-19T20:20:22 < Laurenceb> ok
2015-03-19T20:20:35 < Laurenceb> should i be careful about INT0 and 1 config in the same register?
2015-03-19T20:21:45 < Simon--> yeah, actually, the icp int walks all over it
2015-03-19T20:21:45 < Steffanx> does Laurenceb have the atmega8 datasheet open at page 33?
2015-03-19T20:22:09 < Laurenceb> yes
2015-03-19T20:22:29 < Simon--> in your case, you could just set USE_everything to 0 except I2C
2015-03-19T20:22:55 < Laurenceb> ok
2015-03-19T20:23:14 < Simon--> oh wait, int0 isn't used on that board
2015-03-19T20:23:16 < Simon--> so you're fine

2015-03-19T20:25:38  * Laurenceb has never used avr asm
2015-03-19T20:25:57 < Simon--> whoever invented avr never actually talked to the guys who made 88/328 series
2015-03-19T20:26:07 < Laurenceb> sbi MCUCR, 7
2015-03-19T20:26:22 < Simon--> on the 8, the regs are packed to be mostly (except mcucr :P) reachable by most bit-mod instructions
2015-03-19T20:26:32 < Laurenceb> oh
2015-03-19T20:27:00 < Simon--> n the 48/88/168/328, they just (for no apparent reason) put huge gaps between them all, so now you basically have to use not just in/out but mmio for lots of stuff
2015-03-19T20:27:10 < Simon--> and mmio sucks on avr because the instructions are huge and slow
2015-03-19T20:27:16 < englishman> Steffanx: reason for atmega8 is china bargain basement economics. they are selling $5 escs after all
2015-03-19T20:27:44 < Simon--> so in the case of this particular esc code, the critical parts end up being slower/bigger even though the chip runs at 20MHz
2015-03-19T20:28:14 < Simon--> but yeah. at least it's not a 2560 :)
2015-03-19T20:29:28 < Simon--> all I want is a $.50 arm with muxable comparator ;)
2015-03-19T20:29:46 < superbia> where can i run parametric search

2015-03-19T22:13:05 < qyx_> why do you want m0 for eth?
2015-03-19T22:13:37 < Fleck> cause F091 got 8 UART's :D
2015-03-19T22:13:54 < qyx_> and that's the only reason?
2015-03-19T22:13:58 < qyx_> 6 is not enough?
2015-03-19T22:14:21 < Fleck> maybe 6 is ok also
2015-03-19T22:16:46 < Lux> if wifi is ok, you could use those cheapo esp8266 modules
2015-03-19T22:16:48 < barthess>  Fleck: why not to use SPI-UART bridge?
2015-03-19T22:17:04 < barthess> MAX14830 for example
2015-03-19T22:18:09 < Fleck> barthess: ok, I'll take a look! :)
2015-03-19T22:18:17 < barthess> it is not such ugly like enc28j60
2015-03-19T22:18:29 < Fleck> ;p
2015-03-19T22:18:37 < Fleck> good point! :p
2015-03-19T22:19:38 < qyx_> then it would be good to have something like F401/411 with ethernet
2015-03-19T22:19:48 < qyx_> you either have to use F107 or F407
2015-03-19T22:20:03 < qyx_> the first on is old and the second one is overkill :
2015-03-19T22:20:04 < qyx_> :S
2015-03-19T22:24:48 < barthess>  qyx_: why overkill?
2015-03-19T22:25:33 < barthess>  qyx_: also,  are F401/411 supports Ethernet?
2015-03-19T22:26:29 < qyx_> no, thats the reason i am saying that
2015-03-19T22:27:02 < Fleck> I have DP83848 laying around here... :/

2015-03-20T00:35:38 < edmoore> nothing more fun
2015-03-20T00:35:59 < edmoore> does anyone else have a black magic debug probe that just hangs up every now and then?
2015-03-20T00:36:58 < zyp> not really, no
2015-03-20T00:37:14 < edmoore> wonder if i've a dud
2015-03-20T00:37:15 < zyp> you mean randomly, or under specific conditions?
2015-03-20T00:37:18 < edmoore> or osx is just being silly
2015-03-20T00:37:28 < zyp> I'm using osx myself
2015-03-20T00:37:32 < edmoore> if it is under specific conditions, i haven't determined them and they're not obvios
2015-03-20T00:37:53 < zyp> how new is the firmware you're running?
2015-03-20T00:38:00 < edmoore> maybe every 50th attempt to fire up gdb it fails

2015-03-20T00:38:25 < edmoore> not that new - last time i looked updating the firmware on osx was a pain compared to linux so i thought i'd do it on my thinkpad and i never got my thinkpad
2015-03-20T00:38:31 < edmoore> i'll try and actually do that
2015-03-20T00:38:35 < zyp> uh, what?
2015-03-20T00:38:52 < zyp> it's as straight forward on OS X as it is on linux
2015-03-20T00:38:55 < edmoore> so i might have not parsed the firmware updating stuff correctly?
2015-03-20T00:39:24 < edmoore> i will have another go
2015-03-20T00:39:47 < zyp> I think the included dfu-script might be broken, I tend to just use dfu-util
2015-03-20T00:40:07 < Steffanx> i've only had issues where it sometimes hangs after i issued a load/flash command in gdb
2015-03-20T00:40:14 < zyp> «dfu-util -D src/blackmagic.bin -s 0x8002000»
2015-03-20T00:40:21 < edmoore> thanks
2015-03-20T00:40:54 < zyp> Steffanx, yeah, if something in the commands fails, the comms can come out of sync
2015-03-20T00:41:16 < zyp> I've had that happen, but mainly when I was working on the flash drivers

2015-03-20T09:14:41 < ReadError> like 450$ on ebay
2015-03-20T09:15:02 < zyp> huh, that's cheap

2015-03-20T09:48:49 < zyp> dongs, what's that footprint for 25MHz crystals?
2015-03-20T09:49:18 < zyp> and is it the same for 12MHz, in case I want a smaller crystal for the MCU as well?
2015-03-20T09:50:50 < dongs> 3225
2015-03-20T09:51:01 < dongs> or oyu mean
2015-03-20T09:51:03 < dongs> on dildo?
2015-03-20T09:51:06 < dongs> thats 2520
2015-03-20T09:51:07 < dongs> 16mhz
2015-03-20T09:53:22 < zyp> I just mean, what should I put on this shit?
2015-03-20T09:54:19 < zyp> I already made footprint for that RTC crystal you suggested, and I'm just wondering about going for something smaller for HSE too
2015-03-20T09:54:29 < zyp> and then ethernet needs 25 MHz
2015-03-20T09:56:06 < edmoore> semi-related point - if anyone finds a v small footprint 12MHz tcxo, i'm all ears
2015-03-20T09:56:53 < dongs> oh
2015-03-20T09:57:02 < dongs> i'd use 3225
2015-03-20T09:57:29 < dongs> cant y ou just MCO 25mhz for ethernet?
2015-03-20T09:57:32 < dongs> to save a crystal
2015-03-20T09:58:30 < zyp> hmm, you'd have to be able to generate 25MHz then
2015-03-20T09:58:48 < zyp> maybe if I made HSE 25MHz
2015-03-20T09:59:24 < zyp> but fuck that, I'm not going to experiment with that and fuck it up :p
2015-03-20T10:01:21 < edmoore> looks like fun on the balloon channel with all the high altitude balloons trying to chase the solar eclipse. various things not working
2015-03-20T10:01:32 < dongs> < zyp> maybe if I made HSE 25MHz
2015-03-20T10:01:39 < dongs> but thats 25mhz on f4-disco
2015-03-20T10:01:55 < zyp> what is?
2015-03-20T10:02:14 < zyp> f4-disco have 8MHz HSE
2015-03-20T10:02:47 < zyp> and I'm pretty sure you can't get it to output 25MHz on MCO with default PLL settings
2015-03-20T10:02:50 < dongs> izzit?
2015-03-20T10:02:53 < dongs> oh.
2015-03-20T10:02:54 < dongs> hm
2015-03-20T10:03:14 < zyp> so you'd have to run some retarded sysclk, like 175 MHz, and then that breaks usb
2015-03-20T10:03:36 < zyp> anyway, it's not like crystals are expensive?
2015-03-20T10:03:47 < dongs> yeah, not expensive.
2015-03-20T10:03:55 < dongs> i ahvente tried looking for 12mhz in < 3225 tho
2015-03-20T10:04:08 < dongs> 2520 i used was 16 and 27
2015-03-20T10:04:33 < zyp> that's ok, I'll use 3225
2015-03-20T10:04:54 < zyp> well, I guess I don't have to do 12 MHz
2015-03-20T10:07:18 < zyp> hmm, HSE supports 4-26 MHz, and the PLL can cope with any whole number there, just by setting PLLM to that
2015-03-20T10:09:20 < zyp> might as well just do 2520 then

2015-03-20T10:16:20 < zyp> yeah, it's fine, just set PLLM=25
2015-03-20T10:16:21 < qyx_> but you can usually get sane freq on two steps
2015-03-20T10:16:34 < qyx_> or that

2015-03-20T10:17:40 < qyx_> don't know if 12MHz, 26MHz for sure

2015-03-20T11:22:55 < dongs> my shit was some LGA/leadless shit
2015-03-20T11:23:00 < dongs> i can ask if its afvailable

2015-03-20T11:23:36 < dongs> IP4220CZ6,125 right?
2015-03-20T11:23:43 < zyp> yeah
2015-03-20T11:24:05 < dongs> er duno where 125 shit came from
2015-03-20T11:24:08 < zyp> it was the cheapest thing on digikey, and none of the other options looked any better
2015-03-20T11:24:22 < zyp> no idea, it seems to be an NXP thing
2015-03-20T11:24:29 < zyp> other NXP chips tend to have same shit
2015-03-20T11:24:47 < dongs> why does it need vcc
2015-03-20T11:24:53 < dongs> does it actively protect from something?
2015-03-20T11:25:18 < zyp> it doesn't need vcc
2015-03-20T11:25:25 < dongs> 5 VP supply voltage
2015-03-20T11:25:36 < zyp> but there's a zener on it, that'll protect vbus
2015-03-20T11:28:43 < dongs> oo, it can do two ports, its not inline thing
2015-03-20T11:28:48 < zyp> yeah
2015-03-20T11:28:55 < dongs> anyway, china has htem
2015-03-20T11:28:56 < dongs> lots

2015-03-20T11:29:31 < zyp> I was hoping to find some with built-in 22ohm resistors, but all I could find that had that also had 1.5k built in
2015-03-20T11:29:40 < dongs> heh
2015-03-20T11:29:47 < dongs> not a lot of places need 22R
2015-03-20T11:29:55 < dongs> a lot of cheapass usb shit has it built in
2015-03-20T11:30:22 < zyp> true
2015-03-20T11:32:16 < zyp> okay, next up is doing the power schematic
2015-03-20T11:33:41 < zyp> I guess I have supercap figured out and 3.3V rails will just be plain LDOs
2015-03-20T11:34:56 < zyp> so I need to figure out overvoltage protection on 12V input, and draw a buck to 5V
2015-03-20T11:35:16 < zyp> I think you recommended some buck controller last time
2015-03-20T11:35:29 < zyp> RT7257B
2015-03-20T11:39:06 < zyp> that part looks straight forward enough

2015-03-20T12:27:21 < Taxman> external, yes
2015-03-20T12:29:04 < _Sync_> oh wow the MPS site is completetly fucked
2015-03-20T12:29:19 < Taxman> yeah
2015-03-20T12:29:26 < Taxman> and some datasheets are nda or so :(
2015-03-20T12:30:12 < _Sync_> still wondering what I should use for my servotroller
2015-03-20T12:30:42 < _Sync_> need 15V for the gatedrivers, 5V for the encoder and 3.3V for the controller
2015-03-20T12:30:45 < jpa-> yay eclipse
2015-03-20T12:30:49 < _Sync_> currently it is all analog
2015-03-20T12:30:51 < _Sync_> but eh
2015-03-20T12:30:54 < _Sync_> eh, linear
2015-03-20T12:35:24 < zyp> http://bin.jvnv.net/f/j6lhi.png <- does this look sane?
2015-03-20T12:36:00 < zyp> haven't made a symbol for supercap on vbat yet
2015-03-20T12:36:23 < jpa-> u5 u6 mystery chips
2015-03-20T12:36:34 < zyp> some generic LDO
2015-03-20T12:37:49 < jpa-> does not conform to usb spec because too much caps!
2015-03-20T12:38:12 < zyp> eh, this doesn't have anything to do with USB
2015-03-20T12:38:29 < jpa-> it has usb_vbus
2015-03-20T12:38:39 < zyp> normally this would be powered by 12V on VIN
2015-03-20T12:39:28 < zyp> vbus power is just for when it's used standalone for flashing/testing/debugging/whatever
2015-03-20T12:39:59 < zyp> I assume the buck regulator will cope just fine with 5V feeding back with 0V on VIN
2015-03-20T12:40:14 < jpa-> probably
2015-03-20T12:40:46 < jpa-> no need for polarity protection on 12V input?
2015-03-20T12:41:08 < zyp> not polarity, but I need overvoltage protection
2015-03-20T12:41:58 < zyp> though, I guess polarity protection is just another diode, so adding it probably won't hurt
2015-03-20T12:44:50 < dongs> zyp: i use 75k/24k for r1/2
2015-03-20T12:45:03 < zyp> yeah, that's for 3.3V
2015-03-20T12:45:05 < dongs> oh
2015-03-20T12:45:10 < dongs> youre doing 5V?
2015-03-20T12:45:14 < zyp> 62/11.8 is the suggested values for 5V
2015-03-20T12:45:19 < dongs> ic, k
2015-03-20T12:45:24 < dongs> dont bother with C29 also
2015-03-20T12:45:26 < dongs> waste of space
2015-03-20T12:45:34 < dongs> that 2.2/33 c omp is fine
2015-03-20T12:45:56 < zyp> hmm, right
2015-03-20T12:45:57 < Taxman> dongs: Where do you buy your sunlord chokes?
2015-03-20T12:46:06 < dongs> i use CAP1206 22uF 6.3V X5R for  those 22uFs
2015-03-20T12:46:23 < dongs> Taxman: i tell my chinagirl "need 6045 6.8uH coil" she comes back wiht the sunlord part#
2015-03-20T12:46:47 < Taxman> hehe :)
2015-03-20T12:48:05 < zyp> hmm, what's good choices for D1 and D2? schottky or something with low forward voltage
2015-03-20T12:48:21 < zyp> and D2 needs low reverse leakage too
2015-03-20T12:48:22 < dongs> which d1?
2015-03-20T12:48:54 < zyp> http://bin.jvnv.net/f/j6lhi.png <- D1 and D2 here
2015-03-20T12:49:02 < zyp> D2 is the supercap charge diode
2015-03-20T12:49:08 < dongs> oh i didnt scroll to the right
2015-03-20T12:49:09 < dongs> lol
2015-03-20T12:49:15 < zyp> you need to scroll?
2015-03-20T12:49:31 < zyp> :p

2015-03-20T12:55:13 < edmoore> farnell/datasheet, schemayic, layout
2015-03-20T12:55:23 < dongs> yes
2015-03-20T12:55:28 < dongs> schematic/layout across monitors is great
2015-03-20T12:55:32 < edmoore> yeah
2015-03-20T12:55:37 < edmoore> makes such a nice difference
2015-03-20T12:55:47 < dongs> you click/slect some parts in schema and they highlight in layout and shit, very handy, no need to tab windows etc
2015-03-20T12:55:58 < edmoore> yep
2015-03-20T12:56:25 < dongs> zyp, just pick whaever, 1N4148 lol etc.

2015-03-20T13:55:52 < Lux> shitty china lasercutter?
2015-03-20T13:56:03 < ReadError> yea
2015-03-20T13:56:11 < ReadError> i just need to cut some shitty light ply
2015-03-20T13:56:17 < ReadError> and misc
2015-03-20T13:56:37 < edmoore> everything is shitty

2015-03-20T13:57:00 < Lux> especially those cheap china co2 lasers
2015-03-20T13:57:00 < edmoore> i'm having a shitty bug in my stm32
2015-03-20T13:57:14 < Lux> just make sure you get the alignment right
2015-03-20T13:57:19 < edmoore> but i'm ignoring it in favour of just running the damn test and fixing the bug later
2015-03-20T13:57:23 < Lux> on ours that stuff was all bent
2015-03-20T13:58:02 < _Sync_> and get non suck mirrors
2015-03-20T13:58:19 < edmoore> my box crahses after about 1 minute when installed in a cabinet in the test bay
2015-03-20T13:58:24 < edmoore> and runs happily for hours on the desk
2015-03-20T13:58:29 < edmoore> it's just the best

2015-03-20T14:30:05 < Laurenceb> http://www.sigrok.org/blog/new-protocol-decoders-arm-tpiu-itm-etmv3
2015-03-20T14:31:06 < edmoore> ?
2015-03-20T14:31:37 < Laurenceb> for finding you bug
2015-03-20T14:31:41 < Laurenceb> *your
2015-03-20T14:32:43 < edmoore> o
2015-03-20T14:33:54 < Laurenceb> but youd need a saleae clone plugged in and connected to something in the test bay
2015-03-20T14:34:09 < Laurenceb> ive got some for £4 on ebay
2015-03-20T14:34:31 < edmoore> i have a couple of actual salaes
2015-03-20T14:34:40 < Laurenceb> heh spendy
2015-03-20T14:34:57 < edmoore> i'm standing next to the world's most experimental rocket engine
2015-03-20T14:35:01 < edmoore> salaes are not spendy
2015-03-20T14:35:31 < _Sync_> I was gonna say
2015-03-20T14:35:34 < Laurenceb> lol
2015-03-20T14:35:44 < _Sync_> most tools are cheaper than your time if you need to find a fault
2015-03-20T14:36:12 < edmoore> yep
2015-03-20T14:36:23 < edmoore> although i can't buy that R+S 5GHz scope that i want
2015-03-20T14:36:25 < edmoore> even if it helps
2015-03-20T14:36:28 < edmoore> as that is a bit spendy
2015-03-20T14:36:35 < _Sync_> even if you value an R&D hour just at $100
2015-03-20T14:36:43 < _Sync_> everything under 10k quickly pays for itself
2015-03-20T14:37:33  * Laurenceb is getting confused by lipo discharge curves
2015-03-20T14:37:44 < edmoore> that was an adjustment period from being an undergrad
2015-03-20T14:37:52 < edmoore> just throwing $1000 at a problem to make it go away
2015-03-20T14:37:55 < Laurenceb> its seems 25C outperforms 65C at ~15C discharge
2015-03-20T14:38:03 < Laurenceb> http://rightbattery.com/wp-content/uploads/2013/07/1s-3-7v-600-mah-turnigy-nano-tech-35-70c-lipo-capacity.jpg
2015-03-20T14:38:19 < Laurenceb> why is the voltage at 0A lower
2015-03-20T14:38:54 < Laurenceb> than
2015-03-20T14:38:55 < Laurenceb> http://rightbattery.com/wp-content/uploads/2013/08/3s-11-1v-180-mah-turnigy-nano-tech-25-40c-lipo-battery-capacity.jpg
2015-03-20T14:39:30 < Laurenceb> they changed the chemistry as well as adding more copper foil?
2015-03-20T14:39:32 < _Sync_> haha, depending on what the budget in your university is, that's probably true edmoore
2015-03-20T14:40:10 < edmoore> i helped run a student group
2015-03-20T14:40:13 < edmoore> evenings and weekends
2015-03-20T14:40:16 < edmoore> budget = $0
2015-03-20T14:40:37 < Laurenceb> wait wut
2015-03-20T14:40:39 < _Sync_> we just blew 7M on a new implanter
2015-03-20T14:40:48 < Laurenceb> O_o
2015-03-20T14:40:49 < _Sync_> "because it was cheap"
2015-03-20T14:40:53 < Laurenceb> implanter?
2015-03-20T14:40:57 < Laurenceb> ion implanter?
2015-03-20T14:40:59 < _Sync_> yes
2015-03-20T14:41:03 < Laurenceb> ah
2015-03-20T14:41:11 < Laurenceb> wait wtf
2015-03-20T14:41:21 < Laurenceb>  "65C" lipo fails at 20C
2015-03-20T14:41:33 < Laurenceb> something is clearly screwed in those plots
2015-03-20T14:41:40 < _Sync_> yeah
2015-03-20T14:41:43 < _Sync_> something is fucky
2015-03-20T14:41:55 < edmoore> we have that laminated at work on the side of the test bay
2015-03-20T14:42:06 < edmoore> along with bob widlar giving the photographer the middle finger
2015-03-20T14:42:10 < Laurenceb> i think im going to guess that 65C is better than 25C
2015-03-20T14:42:12 < Laurenceb> lol
2015-03-20T14:42:39 < Laurenceb> aiui most of the difference in C rating is the foil plate thickness / area etc ?
2015-03-20T14:42:48 < _Sync_> probably
2015-03-20T14:43:29 < Laurenceb> hmm
2015-03-20T14:43:47 < Laurenceb> my spin system needs 30A for 200ms, then 3.5A for 600ms
2015-03-20T14:43:57 < _Sync_> but I hate how it is easier to justify buying new machines instead of maintaining old hardware when doing contract research
2015-03-20T14:44:04 < _Sync_> our old implanter still worked
2015-03-20T14:44:05 < Laurenceb> im going to go for 350mah turnigy "nanotech" i think
2015-03-20T14:44:13 < Laurenceb> ive got a working implanter
2015-03-20T14:44:15 < _Sync_> but would have needed some replacement parts
2015-03-20T14:44:18 < Laurenceb> its in my pants
2015-03-20T14:51:51 < Laurenceb> these guys seem to do lots of testing  http://rightbattery.com/
2015-03-20T14:51:59 < Laurenceb> odd that they would screw it up
2015-03-20T14:55:32 < _Sync_> or maybe the cell was shitty
2015-03-20T15:01:39 < Laurenceb> wtf
2015-03-20T15:01:41 < Laurenceb> http://www.maxamps.com/Lipo-6500-74-Pack-T.htm
2015-03-20T15:01:44 < Laurenceb> 150C
2015-03-20T15:02:03 < dongs> <zano> Ohh,is there going to be any more updates on the camera modules? I remember the creators contemplating on the one that will be fitted on by default to be capable of 4K video taking,etc before, not much has been shared regarding the matter since then.
2015-03-20T15:02:07 < dongs> rofl
2015-03-20T15:02:10 < dongs> 4k
2015-03-20T15:03:13 < Laurenceb> going to try this then   http://www.maxamps.com/Lipo-430-111-Pack.htm

2015-03-20T16:22:49 < kakeman> what fight?
2015-03-20T16:23:14 < edmoore> lwip
2015-03-20T16:28:09 < zyp> hmm, looks like I'll have tons of spare area on this board
2015-03-20T16:28:35 < dongs> pic
2015-03-20T16:28:37 < zyp> still missing a couple of buttons and leds
2015-03-20T16:28:39 < dongs> i thought it was empty

2015-03-20T16:28:42 < zyp> http://bin.jvnv.net/f/5pJSo.png
2015-03-20T16:28:58 < dongs> ah, not to bad
2015-03-20T16:29:12 < dongs> .. is that double-sided?
2015-03-20T16:29:38 < zyp> in what sense? only parts on bottom are the stacking connectors
2015-03-20T16:29:48 < dongs> yes, in that sense :)
2015-03-20T16:29:58 < Laurenceb> I think i understand lipo voltage behaviour
2015-03-20T16:30:11 < Laurenceb> its related to cell aspect ratio
2015-03-20T16:30:18 < Laurenceb> long thin cells are worse
2015-03-20T16:30:24 < kakeman> edmoore: can you provide me design hints for basic fixed altitude fixed speed rocket engine?
2015-03-20T16:30:51 < kakeman> :)
2015-03-20T16:31:09 < edmoore> no because that sounds like a missile :)
2015-03-20T16:31:21 < edmoore> rocket propulsion elements by sutton is the good introductory text
2015-03-20T16:31:34 < Laurenceb> i have it on my shelf
2015-03-20T16:31:43 < edmoore> if you read and grok that you'll be able to size up and do a rocket engine conceptual design
2015-03-20T16:31:43 < Laurenceb> not much on spin stabilised solids tho :P
2015-03-20T16:32:03 < dongs> whats wrong with missile design
2015-03-20T16:32:04 < edmoore> it doesn't do a massive treatment of anything in particular (heat transfer or turbopumps or whatever) but it's a very good overview
2015-03-20T16:32:09 < dongs> add in some of those 10kdps gyros
2015-03-20T16:32:28 < edmoore> and huzel+Huang is a better text for more in depth liquid engine design
2015-03-20T16:32:39 < edmoore> i'm not interested in missile design
2015-03-20T16:33:31 < dongs> zyp, gonna need 1mm copper, 1mm border w/omask/copper fiducials in opposite corners
2015-03-20T16:33:55 < zyp> sure
2015-03-20T16:34:03 < zyp> both sides?
2015-03-20T16:35:45 < dongs> http://i.imgur.com/FFEUy7X.png
2015-03-20T16:35:52 < dongs> no, bottom side is ok
2015-03-20T16:36:08 < dongs> in diagonal corners on top side
2015-03-20T16:37:49 < dongs> how i ended up makign the shit work is put 1mm pad, 1mm anti-mask, then a 2mm diameter keepout arc (not keepout layer, but like dashed circle one)
2015-03-20T16:38:07 < dongs> if you dont put keepout arc it fills copper into it until clearance rules
2015-03-20T16:38:45 < zyp> I already have fiducial rules, I made some for arcin
2015-03-20T16:38:56 < dongs> how d id you make them?
2015-03-20T16:39:02 < dongs> just expanded clerance around the 1mm pad?
2015-03-20T16:39:03 < kakeman> edmoore: what do you think about running rocket engine with compressed air?
2015-03-20T16:39:13 < kakeman> instead of oxygene

2015-03-20T16:39:28 < edmoore> it works
2015-03-20T16:39:40 < edmoore> obviously the performance is worse
2015-03-20T16:39:41 < dongs> that looks good
2015-03-20T16:39:47 < edmoore> as 80% by volume is no use

2015-03-20T16:41:05 < kakeman> these books look like legit stuff
2015-03-20T16:41:11 < zyp> it's just a custom SolderMaskExpansion rule, with expansion set to 0.75mm
2015-03-20T16:41:24 < dongs> zyp, but how does that get around copper fill
2015-03-20T16:41:26 < edmoore> kakeman, they are
2015-03-20T16:41:37 < edmoore> RPE is good if you're serious about wanting to get a good grounding in rocket propulsion
2015-03-20T16:41:45 < edmoore> i can't think of a better book off the top of my head
2015-03-20T16:42:24 < edmoore> i'm actually about to go and fire an air+hydrogen engine myself, so it's funny you asked :)
2015-03-20T16:42:42 < dongs> http://i.imgur.com/LrE5xM4.png i have to do this
2015-03-20T16:43:18 < zyp> hang on, let me check
2015-03-20T16:43:23 < kakeman> edmoore: what is burning chamber preasure of air rockets typically around?
2015-03-20T16:43:34 < edmoore> there is no typical thing
2015-03-20T16:43:39 < kakeman> ok
2015-03-20T16:43:45 < edmoore> it will be very specific to your design
2015-03-20T16:43:48 < kakeman> it can be anything
2015-03-20T16:43:55 < edmoore> air+fuel rockets basically don't reallt exist except in a couple of places
2015-03-20T16:44:15 < edmoore> unless you define a jet engine to be one in which case they're everywhere
2015-03-20T16:45:46 < dongs> oh nice, i can put that same cutout into the fiducial component itself
2015-03-20T16:45:50 < dongs> and i dont need t o rmeember to do it on pcb
2015-03-20T16:45:51 < dongs> yay!
2015-03-20T16:46:04 < dongs> so i dont need to make special clerance/etc rules
2015-03-20T16:46:48 < zyp> ah, I have a Clearance_fiducial as well
2015-03-20T16:46:51 < Laurenceb> edmoore: are you familiar with shell stability equations?
2015-03-20T16:46:52 < edmoore> kakeman, i think what will constrain you is the thermal flux into the walls of your combustion chamber
2015-03-20T16:46:58 < edmoore> and how well you can cool that
2015-03-20T16:46:59 < ReadError> i would like to use your pcb factory for boards
2015-03-20T16:47:13 < ReadError> but i dont think u will come off the sores ;(
2015-03-20T16:47:19 < Laurenceb> ive written my own 6dof sim and avoided dealing with that stuff :-S
2015-03-20T16:47:24 < edmoore> Laurenceb, no
2015-03-20T16:47:29 < Laurenceb> ok :P
2015-03-20T16:47:40 < Laurenceb> custom sim says the rockoon needs >10krpm
2015-03-20T16:47:47 < Laurenceb> which seems rather high
2015-03-20T16:47:56 < dongs> zyp, dump all that and make it into a single component
2015-03-20T16:48:00 < edmoore> brb
2015-03-20T16:48:06 < Laurenceb> but i can get 15krpm on the bench, so shrug
2015-03-20T16:50:28 < dongs> http://i.imgur.com/0ldErn1.png this for pad, then make a 'top layer' full arc with same diameter as outside, then tools->convert->convert to region, then chcekbox 'cutout' , and delete the original top-layer arc
2015-03-20T16:50:58 < dongs> then you can just assign it as a footprint for stuff, or just drop on pcb

2015-03-20T17:02:50 < ReadError> great i can move what im looking at up or down
2015-03-20T17:03:00 < gxti> and panning is more precise anyway
2015-03-20T17:03:18 < gxti> so i just changed it to zoom instead.
2015-03-20T17:03:34 < zyp> I find it perfectly intuitive, it's far from the only application with that behavior

2015-03-20T21:09:48 < rkreis> if you find any flaws or anything suspicious (except for the battery being charged from USB, just don't plug both in at the same time!), please tell me :)
2015-03-20T21:11:46 < jpa-> hmm, does STM32L052 require the 22ohm usb resistors? L0 discovery doesn't have them
2015-03-20T21:12:26 < zyp> board I made doesn't have them either
2015-03-20T21:12:35 < zyp> http://bin.jvnv.net/f/u9XvV.JPG
2015-03-20T21:12:39 < rkreis> so, they're not needer or am i actually better off leaving them out?
2015-03-20T21:12:55 < jpa-> better off, if they are not needed it means they are internal to the chip
2015-03-20T21:13:02 < zyp> yeah
2015-03-20T21:13:09 < rkreis> *snip*
2015-03-20T21:13:20 < rkreis> actually, i'll try finding some info in the ds first :)

2015-03-20T21:13:33 < zyp> your schematic doesn't look very minimal compared to mine :)
2015-03-20T21:13:43 < zyp> jpa-, usb to jvs (rs485)
2015-03-20T21:14:05 < rkreis> zyp, heh, i thought it has *two* usb connectors :)
2015-03-20T21:14:11 < zyp> it has
2015-03-20T21:14:17 < jpa-> rkreis: i would add a pull-up resistor to NRST.. there is internal pull-up but it is quite weak
2015-03-20T21:14:20 < zyp> jvs is using usb connectors for rs485
2015-03-20T21:14:27 < gxti> brilliant
2015-03-20T21:14:43 < rkreis> jpa-, alright :)
2015-03-20T21:14:55 < rkreis> zyp, ok, makes sense that way :)
2015-03-20T21:15:27 < rkreis> this will be on a huge 4x5cm board
2015-03-20T21:15:59 < rkreis> which has plenty of room... i tried with an 8 bit avr earlier, and it was way messier
2015-03-20T21:16:23 < rkreis> to be fair, i had a 20 pin jteg header, too
2015-03-20T21:16:46 < jpa-> rkreis: i can't find datasheet for LD117AS33TR; does it allow Vout > Vin without breaking?
2015-03-20T21:17:01 < rkreis> oh, i should totally check that
2015-03-20T21:17:12 < rkreis> you can't find it because it's actually an LD1117 and the eagle lib is dumb
2015-03-20T21:17:20 < jpa-> ah
2015-03-20T21:17:33 < jpa-> the classic 1117
2015-03-20T21:17:39 < jpa-> "very low quiescent current: 5mA"
2015-03-20T21:17:56 < rkreis> :D

2015-03-20T21:18:17 < rkreis> (it doesn't, does it?)
2015-03-20T21:18:29 < Steffanx> it will
2015-03-20T21:18:59 < jpa-> it might; i'm too stupid to understand the schematic in the datasheet
2015-03-20T21:20:26 < zyp> jpa-, while you're at it, can you tell me if RT7257B will allow Vout at 5V while Vin is 0V?
2015-03-20T21:20:48 < jpa-> sure

2015-03-20T21:22:12 < jpa-> i would say yes, as the two output FETs will be off and probably the wire going to the triangle goes to a fet gate also
2015-03-20T21:22:36 < rkreis> any recommendations for a regulator that will not drain any current from Vout when Vin is floating?
2015-03-20T21:22:54 < rkreis> i need VUSB -> 3.3V at 200mA

2015-03-21T00:50:03 < Getty> and software wise, at least PaulFertser can say that vaguely said my code works (as he had to adapt the code to his specific board its not of course "identical")

2015-03-21T01:06:23 < zyp> I bought a 10gbe card, but I didn't have any spare x8 slots left: http://bin.jvnv.net/f/emEVb.JPG
2015-03-21T01:07:22 < Getty> totally worth it then ;)
2015-03-21T01:07:39 < zyp> sure
2015-03-21T01:08:28 < zyp> I just ran a test, reading a big file over nfs, got 390 MB/s
2015-03-21T01:08:38 < zyp> and that's before tweaking any tcp settings or shit
2015-03-21T01:09:00 < zyp> I'm pretty happy with a >3x speedup :p
2015-03-21T01:09:42 < Getty> reminds me of the those times where you bought the first 1gb cards to get full 100mbit on your 100mbit only network
2015-03-21T01:10:08 < zyp> who did that?
2015-03-21T01:10:18 < zyp> I bought 1G cards to get 1G :p

2015-03-21T16:01:22 < specing> well, I wasn't aware of the existance of Ada until about a year ago
2015-03-21T16:02:14 < specing> last time I seriously coded for AVRs/ARMs was well over two years ago
2015-03-21T16:04:09 < Steffanx> assembly => seriously.. :P

2015-03-21T16:08:40 < englishman> sbrs skips next instruction if true, no?
2015-03-21T16:08:49 < englishman> so i2c mode is 1, lext line is skipped

2015-03-21T16:09:03 < englishman> actually its up now -_-

2015-03-21T16:09:17 < englishman> do you even asm

2015-03-21T16:09:53 < Laurenceb_> so it disables the unused stuff
2015-03-21T16:09:57 < Laurenceb_> that makes sense
2015-03-21T16:09:59 < englishman> yeah, must do that
2015-03-21T16:10:08 < Laurenceb_> ok this makes more sense
2015-03-21T16:10:30 < Laurenceb_> so it beeps with three beep_f4 calls
2015-03-21T16:10:38 < Laurenceb_> still very odd
2015-03-21T16:11:10 < Laurenceb_> as im polling it over i2c, and i get commutation count ramping up almost immediately
2015-03-21T16:11:43 < Laurenceb_> pity i cant run any more tests until i get my new hardware finished
2015-03-21T16:12:07 < Laurenceb_> i dismantled the test hardware a couple of weeks ago and only have the data and videos of it running :-/

2015-03-21T20:23:28 < Simon--> Laurenceb_: pong
2015-03-21T20:23:41 < Simon--> yah, it needs to be written in at least inline asm, but the avr C abi sucks balls
2015-03-21T20:23:47 < Laurenceb_> ok
2015-03-21T20:23:56 < Laurenceb_> I think i worked out whats going on now
2015-03-21T20:24:05 < Simon--> you find the beep stuff?
2015-03-21T20:24:06 < Laurenceb_> my matlab code was removing the startup stuff :P
2015-03-21T20:24:14 < Laurenceb_> yeah, i time it as 120ms * 3
2015-03-21T20:24:23 < Simon--> yup
2015-03-21T20:24:24 < Laurenceb_> but the code says 240ms, im confused by that
2015-03-21T20:24:38 < Simon--> I blame quax (I didn't actually write that part)
2015-03-21T20:25:05 < Simon--> you mean wait240ms is wrong?
2015-03-21T20:25:06 < Laurenceb_> wait240ms:	rcall	wait120ms
2015-03-21T20:25:13 < Laurenceb_> i think it only waits 120ms
2015-03-21T20:25:18 < Simon--> oh. that's just typical delay trick
2015-03-21T20:25:23 < Simon--> yaeh, but look at the next instruction
2015-03-21T20:25:33 < Simon--> it's call, not jmp
2015-03-21T20:25:33 < Laurenceb_> oh it calls the next line
2015-03-21T20:25:34 < Laurenceb_> i see
2015-03-21T20:25:58 < Laurenceb_> something seems to be wrong, as it takes 120ms according to my 240fps camera
2015-03-21T20:26:01 < Laurenceb_> but shrug
2015-03-21T20:26:20 < Laurenceb_> i count ~28frames
2015-03-21T20:26:35 < Laurenceb_> so the i2c commutation count will read zero during the beeps?
2015-03-21T20:26:46 < Laurenceb_> oh you didnt write that bit lol
2015-03-21T20:26:51 < Simon--> donno, didn't write that part, but I would guess so
2015-03-21T20:26:58 < Laurenceb_> but commutation will be zero
2015-03-21T20:27:00 < Laurenceb_> yeah
2015-03-21T20:27:01 < Laurenceb_> cool
2015-03-21T20:27:17 < Simon--> just rip it out if you don't want it?
2015-03-21T20:27:25 < Laurenceb_> also one more question, the initial throttle setting over i2c or usart needs to be zero?
2015-03-21T20:27:42 < Laurenceb_> hmm i might leave it, just need to understand whats going on
2015-03-21T20:27:47 < Simon--> yeah. all of the inputs take the same code path, so think of it as "arming" as you do with pwm
2015-03-21T20:27:58 < Laurenceb_> it will make a nice sync signal for the GoPro video
2015-03-21T20:27:59 < Laurenceb_> ok
2015-03-21T20:28:18 < Laurenceb_> ill upload to filebin so you can see what im working on
2015-03-21T20:29:01 < Simon--> do I want to? I'd probably rather see a diff ;)
2015-03-21T20:29:14 < Laurenceb_> i meant a video :P
2015-03-21T20:29:20 < Laurenceb_> of the hardware
2015-03-21T20:29:22 < Simon--> oh cool
2015-03-21T20:29:32 < Laurenceb_> yeah diff is like ten lines lol
2015-03-21T20:29:50 < Simon--> that's like 2 instructions/day coding rate
2015-03-21T20:29:53 < Laurenceb_> im trying not to modify it too much, i just need to understand how it works as my use is very unconventional
2015-03-21T20:29:57 < Laurenceb_> hehe
2015-03-21T20:30:02 < Laurenceb_> wow
2015-03-21T20:30:04 < Laurenceb_> heh
2015-03-21T20:30:11 < Simon--> ;)
2015-03-21T20:30:47 < Simon--> yeah, I think about redoing it in C (I already have on stm32f3).. but I'd probably end up writing my own compiler ;P

2015-03-21T21:29:18 < edmoore> as long as it takes england to not score the single try they need against france
2015-03-21T21:29:28 < edmoore> but srsly like 100ms?
2015-03-21T21:29:32 < edmoore> depends on the davey actually
2015-03-21T21:29:36 < edmoore> some are quick, some are slow
2015-03-21T21:29:41 < edmoore> you want the low ones for motor ignition
2015-03-21T21:29:59 < Laurenceb_> yeah
2015-03-21T21:30:09 < Laurenceb_> ok, i have ~1 second to play with
2015-03-21T21:30:28 < Laurenceb_> before the inertia of the launcher starts to do really bad things to the suspension lines
2015-03-21T21:30:35 < edmoore> that should be fine
2015-03-21T21:30:43  * Laurenceb_ is trying to work out launch sequencing
2015-03-21T21:31:01 < Laurenceb_> i can do 0 to 15krpm in 250ms, so all good so far
2015-03-21T21:31:16 < edmoore> do some tests of course
2015-03-21T21:31:24 < Laurenceb_> yeah
2015-03-21T21:31:25 < edmoore> in thermal vac if poss
2015-03-21T21:31:34 < edmoore> as that is what affects success to a large degree
2015-03-21T21:31:34 < Laurenceb_> i dont have a big enough chamber
2015-03-21T21:31:47 < Laurenceb_> yeah we have tested static ignition
2015-03-21T21:31:50 < edmoore> c.f. the consistant el reg vulture cockups
2015-03-21T21:31:51 < Laurenceb_> in vacuum
2015-03-21T21:31:53 < Laurenceb_> heh
2015-03-21T21:32:08 < Laurenceb_> but the whole launch system is too big to fit
2015-03-21T21:32:25 < Laurenceb_> just a silicone nozzle plug
2015-03-21T21:32:54 < Laurenceb_> is what we used for the static tests, worked fine

2015-03-22T00:39:01 < malinus> I got a stm32f4 discovery board, and trying to flash this blinky example https://github.com/rowol/stm32_discovery_arm_gcc/blob/master/blinky/main.c . It all works fine right after flashing it (led blinks), however, if I reset the device, the program doesn't seem to run. Starting debugging (st-util), seems to "kick-start" the flash too, hence debugging with gdb on the device, shows nothing unusual (to me?).
2015-03-22T00:40:14 < malinus> Any ideas what might be wrong?

2015-03-22T00:48:24 < malinus> Also, even after disconnecting power, I can force the program to run, by launching "st-util". So it must be on the flash, no?
2015-03-22T00:51:51 < Getty> i really love C debugging.... when i yesterday started to learn about the registers of my PHY i thought at first all my changes to it are not existing..... well if you debug just the first 8bit of the 16bit field and do the changes only in the upper 8 bit
2015-03-22T00:52:29 < upgrdman> malinus, are you familiar with gdb?
2015-03-22T00:52:34 < Getty> i will not fall in that trap again, for sure..  i think..... welll i actually dont think but i pretend, but its just crazy that no matter how many years of "upper languages" you have, those kind of stuff is just "new"
2015-03-22T00:53:02 < malinus> upgrdman: somehow, yes. Not an expert however. I know the basics and used it in various scenarios before.
2015-03-22T00:53:39 < upgrdman> malinus, i would start by having gdb reset the mcu, then step through the code line by line. see if anything seems weird.
2015-03-22T00:53:54 < Getty> or set some wise breakpoints ;)
2015-03-22T00:54:06 < upgrdman> nah, just step like a mad man
2015-03-22T00:54:09 < upgrdman> ;)
2015-03-22T00:54:11 < Getty> ;)
2015-03-22T00:54:20 < Getty> ok ok ;) we must tell him that he needs to make it step by step
2015-03-22T00:54:23 < Getty> from start on
2015-03-22T00:54:26 < Getty> thats much more funny, i get it :)
2015-03-22T00:54:45 < upgrdman> no, really, i would in this case. sounds like a startup issue. so step through all of it
2015-03-22T00:55:15 < Getty> oh i wanst actually looking at the case, but in general you should have so much "external debugging" that you see a start point
2015-03-22T00:55:22 < Getty> even tho, yeah, for a beginner, everything counts!
2015-03-22T00:56:17 < qyx_> wat
2015-03-22T00:56:38 < malinus> Okay, actually I'm getting some funky behaviour when debugging. Like, gdb only stops on a breakpoint (in a infinit for loop), once.
2015-03-22T00:57:42 < Getty> hey, tell us what you do, step by step, and we might tell you if its good
2015-03-22T00:57:44 < upgrdman> where do you end up if you ctrl-c while waiting for it to break
2015-03-22T00:58:01 < Getty> i am also totally no gdb expert, but most here are, and they tell you what SHOULD be
2015-03-22T00:58:11 < Getty> (cause if you dont get what SHOULD BE then you have something to fix)
2015-03-22T00:59:11 < malinus> looking at: https://github.com/rowol/stm32_discovery_arm_gcc/blob/master/blinky/main.c I make a breakpoint @ line 27. I run it (with continue), it breaks as expected, I 'continue' again, but it never breaks again. HOWEVER the led keeps blinking.
2015-03-22T00:59:58 < Getty> oh good question i never "reused" a breakpoint, should it recatch?
2015-03-22T01:01:13 < upgrdman> malinus, press ctrl-c in gdb. where do you end up?
2015-03-22T01:02:04 < malinus> upgrdman: oh sorry - was just about to respond. I usually end up on either line 12 or 13. As expected(?).

2015-03-22T01:13:46 < malinus> looks like it
2015-03-22T01:14:06 < malinus> Would you even suggest using the library at all?

2015-03-22T01:14:23 < upgrdman> bsod and everything
2015-03-22T01:15:08 < malinus> I've heard the STM library getting a lot of hate before. Not sure whatever I should try setting everything up by hand instead. Meaning - actually reading the datasheet now :).
2015-03-22T01:15:47 < qyx_> datasheet and reference manual
2015-03-22T01:15:55 < qyx_> you should read them either way
2015-03-22T01:16:20 < malinus> I should. And I will, just wanted to kickstart. Obviously this was the wrong approach.
2015-03-22T01:16:41 < Getty> yeah well.. i also did recently a "kickstart"
2015-03-22T01:16:55 < Getty> and yes, STM32 original libs would assure me "it works" but they are also like 100times more complex
2015-03-22T01:17:06 < Getty> as using like libopencm3 or "public solutions"
2015-03-22T01:17:11 < upgrdman> malinus, my old and not-so-good notes:  http://www.farrellf.com/projects/hardware/2012-06-28_STM32F4_Basics:_GPIOs/
2015-03-22T01:17:18 < Getty> seriously, looking at STM32 code is just HORRIBLE
2015-03-22T01:17:24 < malinus> thanks
2015-03-22T01:17:25 < upgrdman> but theres a quick way to do it without stdperiphlib
2015-03-22T01:17:26 < Getty> its PAIN in the eyes, in the head, and everywhere
2015-03-22T01:18:06 < malinus> Getty: what kind of kickstarter?
2015-03-22T01:18:25 < Getty> not a real  kickstarter, but i made a hardware project with my dad, so i had to dive into all this on my own
2015-03-22T01:18:40 < Getty> i do like 20< years software development, my dad 50< years of device engineering
2015-03-22T01:18:53 < Getty> so it was a bit of an awkward joint venture
2015-03-22T01:19:17 < Getty> but its like, i know whats relevant for "software" and my dad is more thinking "meh its just software i can exchange it"
2015-03-22T01:19:29 < Getty> he values hardware things more as software things, but in the end, if you do software, value it
2015-03-22T01:19:40 < Getty> and the software will play with you
2015-03-22T01:19:44 < qyx_> sometimes the years say nothing
2015-03-22T01:19:45 < Getty> libopencm3 is SUPEREASY
2015-03-22T01:19:50 < Getty> the functions are making sense
2015-03-22T01:19:53 < Getty> and you KNOW what you do
2015-03-22T01:19:55 < Getty> on STM32 libs
2015-03-22T01:20:01 < Getty> you have.....a  lot of not-functions stuff
2015-03-22T01:20:07 < Getty> and a lot of ... things you just copy
2015-03-22T01:20:16 < Getty> its all awkward and all not common coding way
2015-03-22T01:20:20 < Getty> libopencm3 is a charme
2015-03-22T01:20:25 < Getty> you hug it, you like it
2015-03-22T01:20:28 < qyx_> meh, thats the same as comparing chibios+hal to anything else
2015-03-22T01:20:36 < Getty> yeah sure, thats a next step
2015-03-22T01:20:38 < qyx_> chibios is full of defines and static const structs
2015-03-22T01:20:41 < Getty> but in the base first, STM32 libs are just horrible
2015-03-22T01:20:57 < Getty> they are just "provided by producer" but are not "a good thing in the big picture"
2015-03-22T01:21:09 < Getty> they are more like a "Prove of concept" then an actual really plan for a bigger deal
2015-03-22T01:21:18 < Getty> s/really/real/
2015-03-22T01:22:56 < Getty> and yeah, OS means commitment
2015-03-22T01:23:02 < Getty> if you pick an OS, be sure you WANT IT 100%
2015-03-22T01:23:14 < malinus> Getty: OS?
2015-03-22T01:23:19 < Getty> something more as "Just libs"
2015-03-22T01:23:22 < Getty> like chibios
2015-03-22T01:23:28 < Getty> or ..... what else? shit i am too drunk
2015-03-22T01:23:30 < Getty> but if you use a system
2015-03-22T01:23:36 < Getty> you must be 100% sure you dont need to change it
2015-03-22T01:23:39 < Getty> else all your code is worthless
2015-03-22T01:23:50 < malinus> Getty: btw. yes a break should be "reused" each time :)
2015-03-22T01:23:56 < qyx_> wat
2015-03-22T01:23:57 < Getty> malinus: thanks ;)
2015-03-22T01:24:07 < qyx_> Getty: i exchanged chibios with freertos in like 2 days
2015-03-22T01:24:11 < qyx_> without refriting much
2015-03-22T01:24:14 < qyx_> *rewriting
2015-03-22T01:24:25 < Getty> qyx_: cause you are no beginner and did all stuff before in a pretty independent way, cause you know what you do
2015-03-22T01:24:36 < qyx_> of course if your code is ummodular and heavily using its HAL, you have bigger problem
2015-03-22T01:24:39 < Getty> qyx_. if a beginner starts with chibios he will do all in the chibios way, using chibios defines and things
2015-03-22T01:24:51 < qyx_> yes, i have such projects
2015-03-22T01:24:56 < Getty> so on a switch he just can say "fuck it, lets start over"
2015-03-22T01:24:59 < Getty> thats why i say: OS means commitment
2015-03-22T01:25:01 < Getty> caus:
2015-03-22T01:25:14 < Getty> cause: on software its NO commitment, you can often swith OS easily, but on hardware.... => no option
2015-03-22T01:25:37 < Getty> should be pointed out to beginners
2015-03-22T01:26:11 < upgrdman> depends on how much code youve written
2015-03-22T01:26:16 < upgrdman> os can be "flavor of the month" too
2015-03-22T01:26:19 < Getty> yeah sure ;)
2015-03-22T01:26:22 < Getty> can be!

2015-03-22T01:37:43 < Getty> what a luck, eh?
2015-03-22T01:37:44 < Getty> ;)
2015-03-22T01:37:57 < upgrdman> malinus, how is what possible?
2015-03-22T01:38:42 < malinus> upgrdman: that kind of line-jumping. I'm stepping, however it seems to move back and forward.
2015-03-22T01:39:04 < Getty> well often it takes 1000-2000 times till a "IO thing" is back ready
2015-03-22T01:39:05 < upgrdman> normal
2015-03-22T01:39:09 < Getty> step through that 1000-2000 times
2015-03-22T01:39:13 < Getty> then you see its NOT back and forward
2015-03-22T01:39:19 < Getty> its actually just 2000 times forward ;)
2015-03-22T01:39:25 < malinus> upgrdman: really? How so?
2015-03-22T01:39:27 < upgrdman> step tried to step by line of code. 1 line of code is almost never 1 line of assembly
2015-03-22T01:39:33 < Getty> but you are fucking lazy bastard andcomplain already after 200 times hitting continue
2015-03-22T01:39:38 < upgrdman> so it tries to be close
2015-03-22T01:40:11 < malinus> upgrdman: ah okay, thanks
2015-03-22T01:40:24 < malinus> upgrdman: I guess I should look on the asm instead
2015-03-22T01:45:27 < Laurenceb_> just hit enter after the first "c"
2015-03-22T01:45:37 < Laurenceb_> gdb remembers last command
2015-03-22T01:45:56 -!- edmoore [~ed@cpc69047-oxfd25-2-0-cust446.4-3.cable.virginm.net] has quit [Quit: This computer has gone to sleep]
2015-03-22T01:46:09 < malinus> ah yes ofc. :D
2015-03-22T01:46:23 < malinus> upgrdman: also yay, your code works just fine - (seems to reload after resetting)
2015-03-22T01:48:47 < upgrdman> cool
2015-03-22T01:48:53 < malinus> Now I can't rest before figuring out why the other code didn't work.
2015-03-22T01:48:58 < upgrdman> for a lazy blinky led you can spin wait
2015-03-22T01:48:59 < upgrdman> e.g
2015-03-22T01:49:15 < upgrdman> for(volatile uint32_t i = 0; i < 1000000; i++);
2015-03-22T01:49:40 < malinus> gonna take a lot of loops. This guy got a wooping ~150Mhz
2015-03-22T01:49:53 < malinus> :D
2015-03-22T01:49:59 < upgrdman> not a problem
2015-03-22T01:50:44 < malinus> How do you guys usually solder your stm? Oven?
2015-03-22T01:50:45 < upgrdman> 32bit can represent like 4giga
2015-03-22T01:50:53 < upgrdman> hand or hot air
2015-03-22T01:51:03 < malinus> you can do those packages in hand?
2015-03-22T01:51:14 < upgrdman> here my f0: http://www.farrellf.com/projects/hardware/2013-06-01_PCB_Design_and_Etching/
2015-03-22T01:51:23 < upgrdman> yes. flux is your friend.
2015-03-22T01:51:29 < upgrdman> i almost never use oven now
2015-03-22T01:51:35 < upgrdman> hot air or hand solder
2015-03-22T01:52:13 < qyx_> yes, hand solder (drag)
2015-03-22T01:52:14 < malinus> and you did it on some home made board without mask
2015-03-22T01:52:22 < qyx_> some of us do reflow
2015-03-22T01:52:24 < qyx_> oven
2015-03-22T01:52:29 < qyx_> no
2015-03-22T01:52:37 < upgrdman> FUCK the lattice programmer on my xo2 board shit the bed
2015-03-22T01:52:46 < qyx_> you can order pcbs for as low as $1 for 5x5cm
2015-03-22T01:53:16 < upgrdman> malinus, yes. this ugly ass board was 100% hand soldered: http://farrellf.com/temp/assembled_pcb.jpg
2015-03-22T01:53:26 < malinus> yeah pcbs are not a problem. I can even have some (poorly) made for free. Soldering worries me though.
2015-03-22T01:53:53 < malinus> not that ugly :)
2015-03-22T01:54:21 < upgrdman> well my newer stuff is prettier
2015-03-22T01:54:22 < upgrdman> :)
2015-03-22T01:54:43 < upgrdman> like this  http://www.farrellf.com/projects/hardware/2014-09-27_Servo_Tester,_2.4GHz_Spectrum_Analyzer,_Tetris/pic4.jpg
2015-03-22T01:55:32 < malinus> upgrdman: I would be guessing it isn't home made though :D
2015-03-22T01:56:09 < upgrdman> ya
2015-03-22T01:56:14 < upgrdman> it was fab'd in china
2015-03-22T01:56:23 < upgrdman> but this was 100% at home:
2015-03-22T01:56:40 < upgrdman> http://farrellf.com/temp/boost_converter_pcb.jpg
2015-03-22T01:57:13 < malinus> oh that board looks nice
2015-03-22T02:08:53 < malinus> also, if anyone would actually be intrested in why the code I was trying to run before, behaved the way it did (didn't appear to run after restart), here is a great explenation: https://github.com/rowol/stm32_discovery_arm_gcc/issues/1

2015-03-22T06:14:32 < dongs> englishman: sup?
2015-03-22T06:14:39 < englishman> three questions
2015-03-22T06:14:46 < englishman> first, that excellent usb footprint
2015-03-22T06:15:01 < emeb_mac> dongs: not ragequit - still here
2015-03-22T06:15:05 < englishman> so for mounting i put two fills, top and bottom
2015-03-22T06:15:13 < englishman> then a pad with no size for the slotted hole
2015-03-22T06:15:25 < englishman> but then in pcb, i get drc errors that top/bottom are shorted to the pad
2015-03-22T06:15:27 < englishman> how2fix
2015-03-22T06:16:32 < dongs> pads should be same number, i usually use '0' for useless GND ones
2015-03-22T06:16:35 < dongs> http://i.imgur.com/O0rvAsD.png
2015-03-22T06:16:37 < dongs> i have this
2015-03-22T06:16:44 < englishman> but fills dont have numbers
2015-03-22T06:16:48 < dongs> but underneath each dip pad, I also have a top-layer smt with same dimensions
2015-03-22T06:16:49 < dongs> dont use fills
2015-03-22T06:16:51 < dongs> just use a pad
2015-03-22T06:16:53 < englishman> oh you went with simple shit
2015-03-22T06:16:54 < englishman> :/
2015-03-22T06:17:01 < englishman> k
2015-03-22T06:17:09 < englishman> next question
2015-03-22T06:17:14 < englishman> pcb, board area
2015-03-22T06:17:24 < englishman> to export to gerbz, i need to have outline on a mechanical layer right
2015-03-22T06:17:28 < dongs> GKO
2015-03-22T06:17:34 < dongs> put rectangle/. into keepout layer
2015-03-22T06:17:36 < dongs> then select it all
2015-03-22T06:17:45 < englishman> so i do design->board shape -> create primitive
2015-03-22T06:17:48 < dongs> design->board shape->from selected object
2015-03-22T06:17:48 < dongs> yes
2015-03-22T06:17:49 < dongs> no
2015-03-22T06:17:57 < dongs> just draw a rectangle/wahtever on keepout layer
2015-03-22T06:18:02 < englishman> if i put stuff in keepout layer i get drc errors everywhere
2015-03-22T06:18:03 < dongs> then click one line, click tab to select all
2015-03-22T06:18:13 < dongs> why? are your parts so close to it?
2015-03-22T06:18:19 < englishman> sometimes
2015-03-22T06:18:23 < dongs> make gko line like 0.01mm
2015-03-22T06:18:27 < dongs> for board outline
2015-03-22T06:18:27 < englishman> ok
2015-03-22T06:18:32 < englishman> let me try now
2015-03-22T06:18:38 < englishman> 3rd question is 3d parts
2015-03-22T06:18:39 < dongs> it doesnt matter how thin it is, its only used for outline making
2015-03-22T06:18:55 < dongs> if you have stuff that close to the board edge, you might be doing somethign wrong anyway.
2015-03-22T06:19:01 < englishman> ok
2015-03-22T06:19:17 < englishman> i think it error'd the whole thing, but i may have drawn a fill, dont remember
2015-03-22T06:19:34 < dongs> yeah, after you ahve outline you need to t-g-a all the fills
2015-03-22T06:19:45 < dongs> because it adds a small pullback area to fills
2015-03-22T06:19:57 < englishman> so for simple 3d parts, it seems like im supposed to draw a mechanical 1 then use the tools->manage 3d bodies
2015-03-22T06:19:59 < englishman> ah ok
2015-03-22T06:20:12 < englishman> im already tga'ing a lot
2015-03-22T06:20:15 < dongs> you can use any layer really
2015-03-22T06:20:22 < dongs> i use 1 or 13
2015-03-22T06:20:29 < englishman> well only mechanical 1 is available in component editor
2015-03-22T06:20:41 < dongs> no its not
2015-03-22T06:20:41 < dongs> hit l
2015-03-22T06:20:45 < dongs> and you can check any others.
2015-03-22T06:20:53 < dongs> but anyway
2015-03-22T06:20:55 < dongs> layer its on doesnt matter
2015-03-22T06:21:01 < dongs> what is tehre in manage 3d bodies that you cant do elsewhere?
2015-03-22T06:21:03 < englishman> 1 doesnt do anything? only 2 and 3
2015-03-22T06:21:09 < dongs> L not 1
2015-03-22T06:21:11 < englishman> heh
2015-03-22T06:21:14 < dongs> fgt
2015-03-22T06:21:28 < dongs> i coudltn get that dialog to do anything useful
2015-03-22T06:21:40 < englishman> oh cool
2015-03-22T06:21:45 < englishman> yeah its easy
2015-03-22T06:21:50 < englishman> draw mecahnical or whatever
2015-03-22T06:22:01 < englishman> click on "not in component"
2015-03-22T06:22:03 < englishman> set height
2015-03-22T06:22:03 < englishman> done
2015-03-22T06:22:35 < dongs> anyway, back to usb socket, even if you did use a region and then slap a pad into it, and configure mask/paste stuff, it should work
2015-03-22T06:22:39 < dongs> dont see why it would be shorting
2015-03-22T06:22:51 < englishman> yeah i dono either
2015-03-22T06:22:59 < englishman> but theres no way to turn a fill into a pad
2015-03-22T06:23:07 < englishman> and theres no way to have complex shaped pads
2015-03-22T06:23:23 < englishman> despite my googlin

2015-03-22T06:41:12 < englishman> the slotted holes are pads, i tried with designator=0 and designator=null
2015-03-22T06:41:17 < englishman> not in schematic
2015-03-22T06:41:36 < dongs> add pin0 to schematic component for it.
2015-03-22T06:41:48 < englishman> actually in this one i skipped schematic and went right to pcb
2015-03-22T06:41:50 < englishman> but il do that now
2015-03-22T06:43:13 < englishman> added to schematic + hidden

2015-03-22T08:38:10 < Getty> wait, do i see this right, its a chip with like "random pin distance"? ;)
2015-03-22T08:38:12 < dongs> audiophile quality
2015-03-22T08:38:20 < dongs> extra pins cause noise
2015-03-22T08:38:50 < Getty> yeah sure, valid point, still this charts looks like you need a compass to define the holes ;)
2015-03-22T08:39:18 < dongs> this one audiophile guy made a PCB for TQFP48
2015-03-22T08:39:23 < dongs> he didnt put any pads for unused pins
2015-03-22T08:39:25 < Getty> really sad that we didnt get a contract from this audio company

2015-03-22T08:39:52 < Getty> you know for priests and shit
2015-03-22T08:39:53 < PeterM> why didnt they just package it in a standart tssop-38 and make the other pins NC instead of removing the leads
2015-03-22T08:40:04 < dongs> PeterM: cuz linear, its $10 anyway
2015-03-22T08:40:15 < Getty> PeterM: after the fuckup i had with the network, i can understand that people just reduce "problem points"
2015-03-22T08:40:17 < dongs> they can spend extra $ to get tssop38 with pins removed
2015-03-22T08:40:51 < Getty> its funny as long you have someone who knows what he does, else it gets just a horrible experience ;)

2015-03-22T08:47:50 < dongs> i kinda caught up wiht all innovation currently
2015-03-22T08:48:14 < dongs> crapqueue  finally getting smaller
2015-03-22T08:48:24 < PeterM> how'd the teledildonics go?
2015-03-22T08:50:19 < dongs> making 100 'final production' shits this week
2015-03-22T08:50:40 < dongs> had to add a pulldown to motor gate , when mcu was fully power off, the gate would flaot enough to eventualyl start conducting lols
2015-03-22T08:50:52 < dongs> and parts for 5k sitting here
2015-03-22T08:52:35 < PeterM> ahh yeah, thats a good move
2015-03-22T08:52:44 < englishman> PeterM: send it to those zeptobars guys instead
2015-03-22T08:52:51 < englishman> oh, already posted

2015-03-22T08:54:01 < englishman> judging by the ancient russian crap they are always decapping, they are using what they have
2015-03-22T08:54:03 < PeterM> if thats the case i'd throw in some other expensive as fuck LT chips i got
2015-03-22T08:55:51 < PeterM> i've got a few LT3791s and a few LT8490s

2015-03-22T13:01:09 < malinus> ?
2015-03-22T13:01:32 < qyx_> wat
2015-03-22T13:01:42 < qyx_> i am just saying that you don't need to buy another stlinkv2
2015-03-22T13:01:49 < qyx_> you already have one on the devboard

2015-03-22T15:26:01 < dongs> does it become random
2015-03-22T15:27:15 < malinus> dongs: from the very short experience with stm32 - it flots.
2015-03-22T15:27:18 < malinus> *floats, even
2015-03-22T15:28:06 < malinus> dongs: so if nothing connected (no reference), then "random".
2015-03-22T15:29:41 < dongs> thats what i thought
2015-03-22T15:29:46 < dongs> i better bluewire a resistor then
2015-03-22T15:29:56 < malinus> bluewire?

2015-03-22T15:31:33 < malinus> (if we are talking about a stm32 pin at all)
2015-03-22T15:33:47 < zyp> it's only undefined when it's not 0
2015-03-22T15:33:49 < zyp> :p
2015-03-22T15:34:59 < zyp> capacitance tends to keep undefined signals around their last defined level
2015-03-22T15:35:23 < zyp> so it'll probably be low most of the time
2015-03-22T15:36:37 < malinus> touch a cat, and bring your finger close - it won't be low no more :D

2015-03-22T15:38:57 < zyp> malinus, regarding linker scripts, they mainly do two things; the first is defining where you want stuff to go in memory
2015-03-22T15:39:10 < green1> can i save  opened pdf files on foxitreader, as a group ?  so i can reopen those later ?
2015-03-22T15:39:32 < zyp> the second is to export a set of symbols that tells the startup code where stuff actually went in memory, so startup code knows how to initialize the right stuff
2015-03-22T15:39:50 < zyp> and for that reason, startup code goes hand in hand with linker scripts
2015-03-22T15:40:20 < zyp> people tend to use slightly different symbol names, so you can't just mix and match without changes
2015-03-22T15:41:45 < zyp> green1, try #foxitreader, this is not a pdf reader support channel
2015-03-22T15:41:57 < Fleck> or #windows :D

2015-03-22T15:51:08 < zyp> I don't know why the startup code is even assembly, cortex-m were designed to be able to boot directly to C
2015-03-22T15:54:20 < malinus> So I'm guessing most people end up with their own startup-code+linker script?

2015-03-22T15:56:44 < zyp> there's probably mostly people like me who love to waste time that decides to write their own of everything :p

2015-03-22T16:10:11 < malinus> haha
2015-03-22T16:10:43 < zyp> you can just download the tarball, put it somewhere and add it to your path
2015-03-22T16:12:52 < zyp> random distribution-supplied builds tend to have shitty or outright broken multilib support, which results in you linking in code for the wrong architecture, leading to a nice INVSTATE hardfault as soon as you try calling a libc function
2015-03-22T16:15:24 < zyp> a good reason to use something else is along the lines of «I want to use compiler feature X which is not supported in this build, and I know what I'm doing and can ensure that I'm building a correctly working toolchain»
2015-03-22T16:15:48 < dongs> (like when you wanna use armcc)
2015-03-22T16:16:08 < dongs> with "compiler feature X" being "compiling smaller, faster code than gcc 99.999% of the timte
2015-03-22T16:16:14 < zyp> heh
2015-03-22T16:16:22 < zyp> well, all this is gcc specific
2015-03-22T16:17:03 < zyp> dongs, it's good that armcc is building smaller, because you need to make it fit in 32k unless you want to pay :D
2015-03-22T16:17:53 < dongs> that is true
2015-03-22T16:18:01 < dongs> but a bunch of projects for nrf51 abuse it this way
2015-03-22T16:18:22 < dongs> they load softdevice stuff then the main app is generally < 32k unless youre doing something crazy
2015-03-22T16:18:28 < dongs> lets you use a proper compiler/ide
2015-03-22T16:19:00 < zyp> true
2015-03-22T16:19:28 < zyp> I still haven't done a project, even with gcc, that's as large as 32k
2015-03-22T16:21:33 < zyp> arcin is like <7k, and I don't think I've done anything larger yet

2015-03-22T16:28:07 < qyx_> 15K are unit tests, i can drop them
2015-03-22T16:28:29 < qyx_> 411 should be pin and sw compatible

2015-03-22T16:40:40 < qyx_> thats for things like voice and message delivery in a more realtime fashion

2015-03-22T16:43:37 < Laurenceb_> most of the ISM band transceivers have sync pins that are directly driven by the modem hardware
2015-03-22T16:43:46 < Laurenceb_> so you can use them for time of flight

2015-03-22T18:22:50 < qyx_> hm, this is caused by a string constant

2015-03-22T18:23:50 < qyx_> so its not actually a code causing that, it is a const char * parameter

2015-03-22T23:50:13 < zyp> wat
2015-03-22T23:52:21 < qyx_> huh
2015-03-22T23:53:09 < zyp> MAC is a generic term for the block handling the lowlevel part of any protocol stack, an ethernet MAC is a particular thing
2015-03-22T23:53:39 < zyp> the usb cores we have can be called USB MACs
2015-03-22T23:54:57 < qyx_> btw speaking of MACs
2015-03-22T23:55:18 < qyx_> would you include FEC processing in the MAC layer?
2015-03-22T23:55:35 < qyx_> it seems that there is some slight inconsistency
2015-03-22T23:56:06 < zyp> there's always inconsistencies when you try to fit real world implementations into ideological models
2015-03-22T23:56:22 < qyx_> there doesn't seem to be a iso osi layer for doing media level encoding
2015-03-22T23:56:38 < BrainDamage> if it's a soft decisor, adding FEC allows you to adjust the tresholds of the symbols
2015-03-22T23:56:45 < BrainDamage> in the mac layer*
2015-03-22T23:56:56 < zyp> http://en.wikipedia.org/wiki/Media_access_control#Functions_performed_in_the_MAC_sublayer states that FCS is a function of the MAC layer
2015-03-22T23:57:01 < qyx_> but that would need to be implemented probably in the phy layer
2015-03-22T23:57:06 < qyx_> speking of radio
2015-03-22T23:57:38 < zyp> but it doesn't say anything about FEC
2015-03-22T23:57:43 < qyx_> but thats frame checking, not error correction
2015-03-22T23:57:48 < qyx_> yes
2015-03-22T23:57:56 < zyp> well, it says «protection against errors»
2015-03-22T23:58:08 < zyp> whether it's checking or correcting it doesn't really matter, I guess

2015-03-23T01:49:58 < kakeman> why it does not?
2015-03-23T01:50:13 < kakeman> just tried. it seems to do it

2015-03-23T01:52:10 < kakeman> kicad push and shove etc.
2015-03-23T01:58:21 < Laurenceb_> qyx_: two different boards with same firmware?
2015-03-23T01:58:34 < Laurenceb_> and it is consistent on each board if you power cycle?
2015-03-23T01:58:40 < qyx_> Laurenceb_: yes.. and yes
2015-03-23T01:58:46 < qyx_> but like
2015-03-23T01:58:49 < qyx_> priv key is const
2015-03-23T01:58:52 < qyx_> pub key is const
2015-03-23T01:58:58 < qyx_> message is the same
2015-03-23T01:59:03 < qyx_> and yet different signature
2015-03-23T01:59:08 < qyx_> when i move the code around, it changes
2015-03-23T01:59:12 < Laurenceb_> hmm
2015-03-23T01:59:21 < Laurenceb_> maybe race condition involving the hardware timing?
2015-03-23T01:59:31 < qyx_> i am trying in python to see which sig is actually the correct one
2015-03-23T02:00:08 < qyx_> now could be a library function dependent on hardware timing?
2015-03-23T02:00:33 < qyx_> i mean it doesn't use anything external

2015-03-23T08:00:57 < englishman> wow dental xrays are cheap
2015-03-23T08:01:32 < englishman> how do you develop?
2015-03-23T08:01:59 < dongs> uh its USB
2015-03-23T08:02:05 < dongs> oh you mean photo ones
2015-03-23T08:02:12 < dongs> there's some instant shits you can get
2015-03-23T08:02:18 < englishman> cool
2015-03-23T08:02:31 < englishman> i can use dental xray to irradiate enemies
2015-03-23T08:02:37 < dongs> basically like a small pouch that you tear up and squeeze around then run under water and its done
2015-03-23T08:02:40 < dongs> yeah
2015-03-23T08:02:50 < dongs> the ray gun thing is cheap in china like 300bux or someshit
2015-03-23T08:03:00 < englishman> yeah same
2015-03-23T08:04:10 < englishman> you can even see the bonding wires in that xray
2015-03-23T08:04:19 < dongs> yea
2015-03-23T08:04:28 < dongs> thats USB one tho, shitty rez. photo one is way better
2015-03-23T08:05:01 < dongs> http://pbx.mine.nu/random/haxray.jpg thats a photo one
2015-03-23T08:05:14 < dongs> can def see bonding wires.
2015-03-23T08:13:49 < upgrdman> dongs, so you have a usb xray imager? you just place board on it and aim an x-ray source at it?
2015-03-23T08:14:29 < dongs> i hold the shit in hand with sensor behind board, xray it, save pic.
2015-03-23T08:14:44 < upgrdman> link to device?
2015-03-23T08:14:47 < englishman> still less radiation than nearby nagasaki
2015-03-23T08:14:52 < dongs> ^
2015-03-23T08:14:59 < dongs> upgrdman: its kodak rvg dental imaging shit
2015-03-23T08:15:06 < dongs> there's a few, some popup on ebay for cheap occasionally.
2015-03-23T08:16:39 < upgrdman> placing an order with mouser. is there shit you guys tend to forget to order, or tend to throw onto orders?
2015-03-23T08:19:22 < dongs> i usually do and then i ahve to call to add shit up

2015-03-23T08:38:09 < PeterM> i don't use chip inductor i used... lemmeh check digikey order
2015-03-23T08:38:34 < upgrdman> this is smd but not chip. seem reasonable for AA->3.3V? http://www.mouser.com/ProductDetail/Taiyo-Yuden/BRL3225T470K/?qs=sGAEpiMZZMsg%252by3WlYCkU5iuzh4MJmq0zdGqFb4VRwg%3d
2015-03-23T08:40:16 < PeterM> yeah
2015-03-23T08:40:19 < PeterM> should do no worries
2015-03-23T08:40:48 < PeterM> i assume 3v3 @80-120ma
2015-03-23T08:41:04 < PeterM> max ofc
2015-03-23T08:42:19 < upgrdman> ya
2015-03-23T08:43:40 < PeterM> at these low voltages the lowest Vfwd diodes really make a difference too

2015-03-23T12:00:48 < zyp> anything can be used for audio, it's just a question of quality
2015-03-23T12:01:26 < lieron> I understand :-) Question is more if anyone did it an can comment on the quality

2015-03-23T12:05:45 < edmoore> was for detecting instabilities in a gas flow
2015-03-23T12:06:05 < edmoore> i basically used it as a highish bandwidth AC pressure sensor
2015-03-23T12:07:04 < lieron> that's a cool application :-)
2015-03-23T12:08:21 < edmoore> i got into electronics via the cool applications

2015-03-23T12:54:37 < PaulFertser> yots: my point is that in-kernel ftdi driver can set higher speeds and does it correctly at least for some ftdi chips.
2015-03-23T12:55:34 < yots> oh yes, but a quick look at the driver showed they handle this series differently

2015-03-23T12:56:56 < yots> didn't think it was the cause, i supposed if they handle it differently then it's for the purpose of handling it correctly

2015-03-23T16:44:03 < baird> "Does DICSS work with LaTeX?"
2015-03-23T16:44:58 < vvirag> hey! a week ago or so i asked your opinion to get a small version of the stm32f4-discovery board, and we came to the conclusion that Mini-M4 STM32 (from mikroelektronika) is a nice candidate. since then i ordered some, and try to run my already existing app on it. it turned out that the default bootloader, which it gets shipped, supports only 120MHz programs, so they suggested me to use external programmer. as the stm32f4-discovery board support flash
2015-03-23T16:44:58 < vvirag> ing external MCUs, i used it to flash my Mini-M4 board (using SWD interface). However, it seems that the Mini-M4 does not work -- maybe it just doesn't start up? do you think this could happen?
2015-03-23T16:54:29 < PaulFertser> vvirag: just debug it over swd, step-by-step.

2015-03-24T02:41:29 < yan_> can there be a reason why my stm32l152 ignores which GPIO bank to trigger an EXTI interrupt on? I am trying to set it on GPIOB (tried GPIOC as well) but it keeps setting the trigger on GPIOA?
2015-03-24T02:42:17 < dongs> wut
2015-03-24T02:42:49 < zyp> isn't all banks orred together? for EXTI?
2015-03-24T02:42:52 < dongs> ^
2015-03-24T02:43:26 < yan_> I am setting an EXTI interrupt to trigger on falling edge on pin 11 on GPIOB.. (i'm using libopencm3's exti_select_source()) i mean it ignores pin 11 on every other bank except A
2015-03-24T02:43:40 < yan_> configuring with: https://gist.github.com/anonymous/99ee0066cd6b20d11aa4
2015-03-24T02:44:31 < dongs> does one of those configure exti line stuff?
2015-03-24T02:44:42 < dongs> libopencm3 sure likes to rename shit

2015-03-24T02:47:10 < yan_> also, getting the priority of the interrupt from the ISR from the EXTI_PR register returns 0, not 4 (or 4 shifted)
2015-03-24T02:49:06 < zyp> of course it does, there's no priority 4
2015-03-24T02:49:55 < zyp> if you want 0x40, you have to write that
2015-03-24T02:51:33 < yan_> zyp: i mean it has a default priority, but it comes back as 0
2015-03-24T02:51:55 < zyp> no, you're missing the point
2015-03-24T02:52:09 < zyp> there is no priority 4 on stm32

2015-03-24T02:52:37 < yan_> sorry, i meant 20 (16 + 4 in user pri)
2015-03-24T02:53:01 < zyp> stm32 only have four bits of interrupt priority implemented, so the lower four bits will always read 0
2015-03-24T02:53:13 < zyp> you only have priorities 0, 16, 32, and so on
2015-03-24T02:54:00 < yan_> zyp: ugh, i have been assuming the libopencm3 func effectively did set it to pri<<4
2015-03-24T02:54:08 < zyp> no, that's dumb
2015-03-24T02:54:57 < zyp> if you were supposed to use it like that, the registers would read like that
2015-03-24T02:55:32 < yan_> zyp: ok nvic priorities make more sense now, but it's still triggering on GPIOA only
2015-03-24T02:55:50 < GargantuaSauce> never clued into the granular priorities thing. that explains a bit
2015-03-24T02:56:12 < zyp> there is a very good reason for the top bits being implemented rather than the bottom ones
2015-03-24T02:56:43 < GargantuaSauce> hurts portability marginally less
2015-03-24T02:57:02 < zyp> it's so priorities next to each other would fold into each other when you move code to an architecture with lower number of bits, rather than wrapping and fucking up everything
2015-03-24T02:57:08 < GargantuaSauce> yeah
2015-03-24T02:57:19 < GargantuaSauce> makes perfect sense, i just had noidea
2015-03-24T02:57:25 < yan_> zyp: +1, thanks
2015-03-24T02:57:26 < zyp> you're supposed to treat it like a decimal number, 0x80 being like .5

2015-03-24T03:00:06 < zyp> yan_, by the way, have you turned on the SYSCFG clock?
2015-03-24T03:00:34 < yan_> hmm
2015-03-24T03:00:53 < zyp> the EXTI registers are located in the SYSCFG block
2015-03-24T03:01:27 < zyp> no, actually, only the EXTI source registers are
2015-03-24T03:01:40 < GargantuaSauce> bingo
2015-03-24T03:01:56 < zyp> so that explains why trigger/enable config works but not source selection

2015-03-24T03:07:36 < zyp> I think sleep mode can turn off stuff like that automatically

2015-03-24T03:08:40 < zyp> but I'd argue that you shouldn't worry about it before you have to

2015-03-24T05:01:09 < englishman> R2COM: all hobby uav shit is amateur analolgue video shit
2015-03-24T05:01:16 < englishman> thers a couple digital systems for $800-2k
2015-03-24T05:01:21 < englishman> but nobody uses them
2015-03-24T05:01:38 < englishman> 150k long distance records etc. on <1w transmitters usually
2015-03-24T05:01:47 < dongs> none
2015-03-24T05:01:50 < englishman> hd video
2015-03-24T05:03:21 < GargantuaSauce> lol
2015-03-24T05:03:40 < GargantuaSauce> good luck with that
2015-03-24T05:05:13 < englishman> h.264
2015-03-24T05:05:39 < englishman> DJI INSPIRE ONE for $2900 is ready to fly quadcopter with digital wireless hd video
2015-03-24T05:05:40 < GargantuaSauce> yeah and then you get packet loss during a keyframe and a couple seconds of garbage
2015-03-24T05:05:54 < GargantuaSauce> quality
2015-03-24T05:06:18 < englishman> yeah, analolgue video it is much easier to view weak signal, interference etc manually
2015-03-24T05:06:28 < englishman> and to have short dropouts even
2015-03-24T05:06:32 < GargantuaSauce> or perhaps you use a reliable transport protocol and then you get variable latency
2015-03-24T05:06:34 < GargantuaSauce> great for flying
2015-03-24T05:07:27 < GargantuaSauce> if you come up with a good solution i will buy it
2015-03-24T05:07:44 < dongs> just use OFDM and send with a bunch of FEC but thats still worse than analog
2015-03-24T05:09:14 < dongs> there is one chip mpeg2ts>ofdm transmitter (dvb-t, isdb-t standards). they're cheap, too. even in samples. you can combine with a low latency h264 encoder and have a decent link, but most people wont like it cuz of latency
2015-03-24T05:10:37 < dongs> ive had one in my desk drawer for nearly 2 years now
2015-03-24T05:10:50 < dongs> if I would get off my ass i could probly make some cash from dumb drone flyers
2015-03-24T05:13:21 < dongs> huh?
2015-03-24T05:13:23 < dongs> affordable fpga?
2015-03-24T05:13:28 < dongs> the ofdm>rf chip is a few bucks
2015-03-24T05:13:31 < dongs> like < $5
2015-03-24T05:13:34 < dongs> in samples
2015-03-24T05:14:07 < dongs> it takes parallel/serial mpeg2ts
2015-03-24T05:14:21 < dongs> you can get mpegts out of pretty much any SoC w/hardware mpeg encoder
2015-03-24T05:14:36 < dongs> or specialized ch ip, like BT858 whatever shit -> h264/mpeg encode -> TS out
2015-03-24T05:14:54 < dongs> parallel rgb , BT.something i forget the number
2015-03-24T05:15:05 < dongs> yes
2015-03-24T05:15:09 < dongs> yea
2015-03-24T05:15:39 < dongs> $2000 apple tax
2015-03-24T05:15:49 < dongs> i duno wat dji wankton does
2015-03-24T05:16:10 < GargantuaSauce> well you cant really get away with selling a product that transmits in the dvb spectrum can you?
2015-03-24T05:16:22 < GargantuaSauce> dji uses wifi
2015-03-24T05:16:31 < dongs> GargantuaSauce: you dont have to
2015-03-24T05:16:35 < dongs> the chip outputs IF
2015-03-24T05:16:37 < dongs> you can mix it wiht wahtever LO
2015-03-24T05:16:49 < dongs> you can transmit same "ofdm" in 2.4g
2015-03-24T05:16:51 < GargantuaSauce> well if you want an off the shelf receiver i mean
2015-03-24T05:16:51 < dongs> if y ou want really
2015-03-24T05:17:01 < dongs> yeah, but they have pair receiver chips too
2015-03-24T05:17:09 < dongs> or you can just use anything off the shelf
2015-03-24T05:17:15 < dongs> and use a different tuner frontend
2015-03-24T05:17:19 < dongs> that picks up from 2.4ghz or whatenot
2015-03-24T05:17:29 < GargantuaSauce> and then hope nobody walks nearby with their phone V
2015-03-24T05:17:49 < dongs> heh
2015-03-24T05:18:50 < GargantuaSauce> do you want a pony too
2015-03-24T05:36:08 < dongs> hm chinagirl claims her fab can do 2/2mil trace/space
2015-03-24T05:37:52 < GargantuaSauce> that is...impressive?
2015-03-24T05:38:05 < dongs> yeah
2015-03-24T05:38:18 < dongs> maybe  i can do some 0.5mm pitch bga junk and route not one but TWO traces between ballz
2015-03-24T05:38:54 < dongs> still garbage silk tho
2015-03-24T05:39:25 < GargantuaSauce> with traces like that you can practically use copper space for part designations and whatever
2015-03-24T05:40:07 < dongs> GargantuaSauce: hm?
2015-03-24T05:40:14 < dongs> write refdes in copper?
2015-03-24T05:40:36 < dongs> i've done some text using unmasked copper, it looks super pro
2015-03-24T05:40:38 < GargantuaSauce> yeah if you arent using pro black soldermask
2015-03-24T05:52:30 < dongs> no way???
2015-03-24T05:52:35 < dongs> you better email hello@flyzano.com
2015-03-24T05:52:37 < dongs> with those news
2015-03-24T05:52:57 < GargantuaSauce> wifi sucks
2015-03-24T05:59:40 < GargantuaSauce> limited buffer space and probably negotiating a pretty conservative bitrate

2015-03-24T06:02:14 < GargantuaSauce> so it can send without the master's participation
2015-03-24T06:02:26 < dongs> all those stm32+broadscum shits use "ThreadX" rtos
2015-03-24T06:02:32 < dongs> some payware shit w/payweare IP stack
2015-03-24T06:02:41 < dongs> just sayin
2015-03-24T06:02:43 < dongs> it should be pretty pro
2015-03-24T06:02:45 < dongs> cuz its payware
2015-03-24T06:02:49 < dongs> youre probly not using it corectly
2015-03-24T06:02:57 < dongs> were you dumping all this data with UDP?
2015-03-24T06:02:59 < dongs> or TCP?
2015-03-24T06:03:01 < dongs> and waiting for acks
2015-03-24T06:03:04 < dongs> for each fucking packet
2015-03-24T06:03:09 < dongs> well wtf
2015-03-24T06:03:11 < dongs> what do you expect then
2015-03-24T06:03:33 < dongs> douknohowTCPworks???????????????????
2015-03-24T06:03:57 < dongs> repeat your test blasting UDP, and it might do a fair bit better
2015-03-24T06:05:17 < dongs> you dont need each packet to be delivered
2015-03-24T06:05:29 < dongs> frame your UDP packets with sequence and some FEC if you're worried
2015-03-24T06:05:36 < dongs> manage retransmissions when needed
2015-03-24T06:06:02 < englishman> you need each packet delivered but you arent waiting for acks?
2015-03-24T06:06:34 < dongs> im saying thats why its slow tho
2015-03-24T06:11:01 < dongs> haha dude
2015-03-24T06:11:03 < dongs> like FSK
2015-03-24T06:11:04 < dongs> or wahtever
2015-03-24T06:11:16 < dongs> why would you care about bandwidth
2015-03-24T06:11:17 < dongs> on a mouse?
2015-03-24T06:14:40 < dongs> pretty sure wifi cameras use rtp of some kind
2015-03-24T06:14:49 < dongs> unless you talking those non-pro mjpeg shits
2015-03-24T06:14:51 < dongs> that work with browser
2015-03-24T06:14:59 < dongs> but high bandwidth stuff will use rtp
2015-03-24T06:15:28 < dongs> also you generally dont care if you lose a packet of camera live  video
2015-03-24T06:21:53 < dongs> god damn, my pal is drawing a schematic in altidong and it looks like complete shit http://i.imgur.com/E4AX6H5.png
2015-03-24T06:22:05 < dongs> those f ucking traces
2015-03-24T06:22:10 < dongs> he might as well be using eagle
2015-03-24T06:22:50 < dongs> also he managed to use like 6 different values of 4x resistor arrays
2015-03-24T06:23:01 < dongs> how do i DFM???

2015-03-24T06:58:34 < dongs> i mean what does that achieve?
2015-03-24T06:58:39 < dongs> was the package broken or something
2015-03-24T06:58:46 < dongs> that prevented it from using you know, sane mounting methods?
2015-03-24T06:58:53 < dongs> or is it just one of those"i did it because icould" shits

2015-03-24T07:01:41 < GargantuaSauce> i have a hard time believing wiring that up took less time than waiting for a pcb to ship
2015-03-24T07:01:51 < dongs> hasha
2015-03-24T07:02:14 < dongs> yea, waht do you do if you get a ball disconect in teh mdidle

2015-03-24T13:23:11 < dongs> the frequency bands are all built in?
2015-03-24T13:23:16 < dongs> or depends on model#?
2015-03-24T13:26:13 < dongs> A package size of 0201 is
2015-03-24T13:26:14 < dongs> recommended but a 0402 is acceptable.
2015-03-24T13:26:18 < dongs> well, thanks TI
2015-03-24T13:26:25 < dongs> i'll use 0402
2015-03-24T13:27:41 < Laurenceb> looks like they do 868 and 916
2015-03-24T13:27:59 < dongs> 1st page of the pdf you linked mentions liek 5 bands
2015-03-24T13:28:03 < dongs> from VHF  to UHF
2015-03-24T13:28:08 < Laurenceb> i meant the module

2015-03-24T16:32:31 < dongs> in demo  video it lands on your HAND

2015-03-24T16:36:01 < zyp> okay

2015-03-24T16:37:02 < dongs> 6. Motor testing is coming along very nicely. We are narrowing in on the most efficient motor. We had over 20 of the same physical size from various manufacturers to test. We should have this completed within the next week to ten days.
2015-03-24T16:37:11 < dongs> they ordered motors t hat they havent tested yet???????????????
2015-03-24T16:37:45 < dongs> what is this bullshit generalization anyway
2015-03-24T16:37:48 < dongs> <over xx> of something
2015-03-24T16:37:49 < _Sync_> well dongs I need 15V for gate drive, 5V for some logic shit and 3.3V for the stm
2015-03-24T16:37:55 < _Sync_> which is annoying
2015-03-24T16:38:11 < dongs> synic: start wiht 5V, use voltage doubler trash for 15V, ldo for 3.3V
2015-03-24T16:38:29 < dongs> zano it up
2015-03-24T16:39:09 < synic> it's always some guy named sync who screws me over
2015-03-24T16:39:14 < dongs> yeah
2015-03-24T16:39:16 < _Sync_> yeah
2015-03-24T16:39:23 < dongs> pumpers need new nicks
2015-03-24T16:39:28 < dongs> so unoriginal
2015-03-24T16:39:30 < synic> ;-)
2015-03-24T16:39:37 < _Sync_> well, eh
2015-03-24T16:39:43 < _Sync_> I got 24V in that thing
2015-03-24T16:40:04 < dongs> time to use that  MPS2403 thing
2015-03-24T16:40:24 < _Sync_> and depending on the load the gate drive might take a bit
2015-03-24T16:40:42 < _Sync_> so I thought 24 -> 15 and then down the order
2015-03-24T16:40:45 < _Sync_> but bleh
2015-03-24T16:40:48 < _Sync_> dem real estate
2015-03-24T16:41:02 < dongs> i thought the gate vcc stuff is very low current
2015-03-24T16:41:21 < dongs> which is why chinks usually use cheapo capacitor voltage doublers for it
2015-03-24T16:41:25 < _Sync_> controlling 8 power fets
2015-03-24T16:41:41 < _Sync_> at full tilt 2W or so for gate drive
2015-03-24T16:41:42 < dongs> yes, controlling like ~30 cascaded fets
2015-03-24T16:42:01 < dongs> but doesnt driver IC have your 24V also?
2015-03-24T16:42:08 < dongs> which is where it would be drawing from mostly
2015-03-24T16:42:24 < dongs> and 15V is for something low-current
2015-03-24T16:42:40 < dongs> at least that was my udnerstanding last i looked,i dont  even know what part youre using.
2015-03-24T16:44:15 < dongs> hmm I got TXB0104 ordered last june or so. I wonder if I will be able to find them
2015-03-24T16:44:17 < _Sync_> well I guess I could connect the drivers to the 24V
2015-03-24T16:44:18 < _Sync_> hmm
2015-03-24T16:44:35 < dongs> some might not take it taht high.
2015-03-24T16:45:12 < _Sync_> using ir2184 trash, they can't take it
2015-03-24T16:45:13 < _Sync_> 20V max
2015-03-24T16:45:49 < dongs> absolute max 25V
2015-03-24T16:45:50 < dongs> live on the edge
2015-03-24T16:46:14 < dongs> anyway
2015-03-24T16:46:16 < dongs> lowside min is 10V
2015-03-24T16:46:55 < _Sync_> yeah
2015-03-24T16:47:07 < _Sync_> probably just going to leave the three linear vregs on there
2015-03-24T16:47:10 < _Sync_> and see how it works
2015-03-24T17:02:07 < dongs> hm. still not found txb0104
2015-03-24T17:04:06 < dongs> ah there it is

2015-03-24T17:20:11 < ReadError> <Ollis> Hi, Im playing around with the CC3D on a new build. When the FC reboots the USB port stop working, Is there a workaround without removing the USB cable ?
2015-03-24T17:20:11 < ReadError> <pulsar> Ollis: works "as designed"
2015-03-24T17:20:12 < ReadError> <pulsar> or implemented
2015-03-24T17:20:12 < ReadError> <pulsar> whenever the fc reboots, the usb stack is not re-initialized properly
2015-03-24T17:20:12 < ReadError> <Ollis> lol, is it design to bee slow as well ?
2015-03-24T17:20:12 < ReadError> <pulsar> yup
2015-03-24T17:20:12 < ReadError> <pulsar> the VCP implementation is better than nothing but far away from fun
2015-03-24T17:20:39 < dongs> well, hes not wrong about usb
2015-03-24T17:20:47 < dongs> saveds a gpio for disconnect
2015-03-24T17:20:57 < dongs> but that means  usb stack must initialize very quickly at boot
2015-03-24T17:21:13 < pulsar> hmm?
2015-03-24T17:21:39 < dongs> hmm wat
2015-03-24T17:21:40 < ReadError> unplugging and replugging a board doesnt sound like a good solution
2015-03-24T17:21:52 < dongs> but thats the only way to do it the way hardware is done
2015-03-24T17:22:01 < pulsar> nvm. going back to idle.
2015-03-24T17:22:27 < edmoore> a good epitaph^

2015-03-24T18:55:00 < dongs> just went through my inbox and cleaned shit up to march 1st
2015-03-24T18:55:05 < dongs> found a few emals I didnt reply : (
2015-03-24T18:55:20 < dongs> i really need to switch to outlook, gmail folders/labels shit is idiotic
2015-03-24T18:55:24 < dongs> for actually getting any work done
2015-03-24T18:55:25 < Laurenceb> scummos: for launching rockets from balloons
2015-03-24T18:55:39 < scummos> *from* balloons, wow
2015-03-24T18:55:48 < scummos> what do you do with those rockets?
2015-03-24T18:55:58 < dongs> Laurenceb is already on one homeland secuirty watchlist, he wants to get on others
2015-03-24T18:56:07 < Laurenceb> get to 100km
2015-03-24T18:56:10 < Laurenceb> lol
2015-03-24T18:56:17 < dongs> 100km? fuck off
2015-03-24T18:56:26 < scummos> wow 100km
2015-03-24T18:56:27 < dongs> what kinda propulsion do you think you will use for that
2015-03-24T18:56:37 < Laurenceb> official boundary of space
2015-03-24T18:56:41 < dongs> thats getting into super pro territory
2015-03-24T18:56:47 < Laurenceb> off the shelf HPR reloads
2015-03-24T18:56:49 < scummos> you need quite a rocket for that, no? to get from the ... 40km? of the balloon to 100
2015-03-24T18:57:15 < Laurenceb> most cheap HPR reloads will do 100km if there is virtually no drag
2015-03-24T18:57:36 < scummos> (I will not ask how you ever want to get a approval for launching that thing :D)
2015-03-24T18:58:08 < BrainDamage> you get NOTAM for the balloon
2015-03-24T18:58:24 < Laurenceb> rocket launch is outside of controlled airspace
2015-03-24T18:58:31 < dongs> jej
2015-03-24T18:58:32 < Laurenceb> the rocket is safe according to FAA
2015-03-24T18:58:42 < dongs> is there gonna be video
2015-03-24T18:58:44 < dongs> or wat
2015-03-24T18:58:45 < Laurenceb> too light to cause death :P
2015-03-24T18:58:51 < scummos> if it launches into the wrong direction it will get into controlled airspace quickly :D
2015-03-24T18:58:54 < Laurenceb> yes, theres a gopro onboard
2015-03-24T18:59:00 < Laurenceb> scummos: no
2015-03-24T18:59:01 < kekman> http://paste.dy.fi/60K weird round up in line 10. why?
2015-03-24T18:59:03 < dongs> why not a mobius
2015-03-24T18:59:09 < Laurenceb> it disintegrates quickly
2015-03-24T18:59:16 < scummos> it ... disintegrates?
2015-03-24T18:59:19 < Laurenceb> yes
2015-03-24T18:59:31 < scummos> how can I imagine that?
2015-03-24T18:59:44 < Laurenceb> it will rip itself apart if it goes in the wrong direction
2015-03-24T18:59:57 < scummos> because of the additional acceleration?
2015-03-24T19:00:06 < Laurenceb> because of the air desnity
2015-03-24T19:00:10 < BrainDamage> because the further you godown the higher the density
2015-03-24T19:00:11 < scummos> aah, I see
2015-03-24T19:00:14 < BrainDamage> and therefore friction
2015-03-24T19:00:34 < Laurenceb> its not really friction
2015-03-24T19:00:45 < Laurenceb> more a case of inertia of the displaced air
2015-03-24T19:01:04 < dongs> Laurenceb: so how will youmake sure the trash launches "up"
2015-03-24T19:01:08 < Laurenceb> CF honeycomb is fun once you get past the initial learning curve
2015-03-24T19:01:09 < dongs> instead of "burn down"
2015-03-24T19:01:09 < scummos> hmm, does it make much of a difference whether you launch the rocket from 0km or from 40km altitude-gain wise? I thought most of the counterforce would come from the gravitational potential
2015-03-24T19:01:20 < Laurenceb> dongs: hang the payload the right way up
2015-03-24T19:01:25 < scummos> :D
2015-03-24T19:01:35 < dongs> Laurenceb: then it will go right through teh baloon
2015-03-24T19:01:40 < Laurenceb> shrug
2015-03-24T19:01:41 < dongs> probly entanling itself in that shit
2015-03-24T19:01:43 < BrainDamage> scummos: the same rocket if launched from ground would do 100m or so
2015-03-24T19:01:47 < dongs> entangling
2015-03-24T19:01:55 < Laurenceb> its doing Mach 1.3 when it hits the envelope
2015-03-24T19:02:14 < dongs> how many tries do you get
2015-03-24T19:02:17 < dongs> wiht this
2015-03-24T19:02:18 < scummos> ah hm, so it is very quick-burning
2015-03-24T19:02:23 < Laurenceb> going to pick up a few mg of envelope max
2015-03-24T19:02:29 < Laurenceb> 1 try :P
2015-03-24T19:02:32 < scummos> :D
2015-03-24T19:02:41 < Laurenceb> well - as many as i can be bother to attempy
2015-03-24T19:02:45 < Laurenceb> *t
2015-03-24T19:03:06 < BrainDamage> laurencebsat, fire #376
2015-03-24T19:03:14 < Laurenceb> lol
2015-03-24T19:03:14 < scummos> mach 1.3 in a few meters sounds like the engine basically explodes
2015-03-24T19:03:19 < Laurenceb> yup
2015-03-24T19:03:21 < scummos> how long does the engine burn?
2015-03-24T19:03:28 < Laurenceb> 1.5 seconds
2015-03-24T19:03:33 < dongs> uh
2015-03-24T19:03:33 < scummos> ok
2015-03-24T19:03:36 < dongs> and  you expect
2015-03-24T19:03:38 < dongs> to go 60km
2015-03-24T19:03:40 < dongs> form that?
2015-03-24T19:03:46 < Laurenceb> no
2015-03-24T19:03:54 < Laurenceb> 110km according to sim code
2015-03-24T19:04:00 < Laurenceb> so 150km total altitude
2015-03-24T19:04:01 < scummos> ;D
2015-03-24T19:04:06 < dongs> no way
2015-03-24T19:04:17 < BrainDamage> did you have to reshape the nozzle?
2015-03-24T19:04:28 < Laurenceb> not yet
2015-03-24T19:04:38 < Laurenceb> im going to do that once i can find a decent lathe
2015-03-24T19:05:39 < BrainDamage> what tracking system do you use? gps+imu onboard sent as telemetry?
2015-03-24T19:05:40 < kekman> mach 1.3 ibn few meters?
2015-03-24T19:05:49 < kekman> what are you guys doings?
2015-03-24T19:05:58 < BrainDamage> or do you use time of arrival of a beacon
2015-03-24T19:06:13 < Laurenceb> BrainDamage: synthetic aperture on the ground
2015-03-24T19:06:45 < kekman> is it most optimum way to lauch to burn fast and reach maximum velocity quickly?
2015-03-24T19:06:52 < Laurenceb> kekman: no
2015-03-24T19:06:58 < BrainDamage> not from the ground
2015-03-24T19:07:03 < Laurenceb> but thats what off the shelf reloads do
2015-03-24T19:07:09 < Laurenceb> so thats what we are stuck with
2015-03-24T19:07:18 < BrainDamage> from space, not much either, it's not very controllable, etc
2015-03-24T19:07:22 < kekman> create your own
2015-03-24T19:07:39 < Laurenceb> thats no legal without a ton of paperwork
2015-03-24T19:07:47 < Laurenceb> also its hard at this scale
2015-03-24T19:07:58 < Laurenceb> to get much longer than a few seconds

2015-03-24T20:11:07 < gxti> input packets will only be chained if you made them that way
2015-03-24T20:11:40 < gxti> output packets, depends on where they came from. i think with TCP you can get them if it puts multiple chunks into one segment.

2015-03-24T20:15:22 < kekman> UDP
2015-03-24T20:15:59 < gxti> in UDP lwip isn't going to cause any chaining itself
2015-03-24T20:16:13 < kekman> good
2015-03-24T20:17:50 < gxti> just make sure your outgoing pbufs have enough room for headers
2015-03-24T20:19:31 < gxti> i.e. pbuf_aloc(PBUF_TRANSPORT, ...)
2015-03-24T20:20:38 < gxti> that way it can just move the pointer back and scribble the header into the existing pbuf, otherwise it has to allocate a new one and chain your data to it.

2015-03-24T20:25:17 < GargantuaSauce> doing anything in the bootloader menu voids the warranty of most devices i think
2015-03-24T20:25:21 < GargantuaSauce> it's not for consumer use
2015-03-24T20:26:26 < GargantuaSauce> and prettying it up would bloat it and make it more fault-prone anyway
2015-03-24T20:26:26 < kekman> ethernet padding is some sort of alignment hack?
2015-03-24T20:26:46 < gxti> kekman: yes.
2015-03-24T20:26:57 < kekman> oh it doesn't leave the mcu
2015-03-24T20:27:04 < gxti> right.
2015-03-24T20:27:54 < kekman> I was thinking for a time it's some sort of ethernet property to add paddings between packets
2015-03-24T20:28:20 < gxti> no, it just shifts alignment of pbuf by 2 bytes so the IP header starts on a word boundary
2015-03-24T20:28:32 < kekman> you use it?
2015-03-24T20:28:35 < gxti> yes
2015-03-24T20:29:00 < kekman> difference?
2015-03-24T20:29:16 < gxti> speed, probably. haven't tested it.
2015-03-24T20:29:43 < gxti> unaligned accesses are slow, and on some architectures (like cortex-m0) they fail
2015-03-24T20:31:07 < kekman> if I add padding do I need to pay attention to something?
2015-03-24T20:31:40 < gxti> if you copied low-level input and output from somebody else it probably works already
2015-03-24T20:32:23 < kekman> no I have to write my own

2015-03-24T21:32:58 < kekman> in low level input

2015-03-24T23:23:44 < Laurenceb_> lol download
2015-03-24T23:24:01 < Laurenceb_> malinus: its for launching rockets from balloons
2015-03-24T23:24:20 < malinus> oh, that's pretty cool. What is the stm used fore?
2015-03-24T23:24:21 < malinus> *for
2015-03-24T23:24:54 < Laurenceb_> controller/datalogging/uplink/downlink etc
2015-03-24T23:25:37 < malinus> why would one launch rockets from a balloon :)?
2015-03-24T23:25:45 < malinus> Like fireworks?
2015-03-24T23:25:49 < Laurenceb_> theres a 434mhz link to the payload, then the stm32 controls stuff
2015-03-24T23:26:08 < Laurenceb_> no, Karman line
2015-03-24T23:26:22 < Laurenceb_> balloon to ~40km then rocket to >100km altitude
2015-03-24T23:27:25 < Laurenceb_> so that thing spins the rocket up at close to 20k rpm then launches it

2015-03-24T23:28:06 < BrainDamage> actually that makes me wonder, have you run a sim for horizontal range?
2015-03-24T23:28:15 < Laurenceb_> yes
2015-03-24T23:28:26 < Laurenceb_> depends how bad the launch goes :P
2015-03-24T23:28:32 < Laurenceb_> theres lots of failsafes
2015-03-24T23:28:44 < Laurenceb_> and its got human oversight too
2015-03-24T23:28:49 < BrainDamage> what's the longest you can reach?
2015-03-24T23:28:56 < Laurenceb_> actual launch is via uplink only
2015-03-24T23:29:05 < Laurenceb_> i have actually tried that
2015-03-24T23:29:16 < scummos> any chance to get into orbit with that tactics?
2015-03-24T23:29:16 < Laurenceb_> its going to depend on re entry dynamics
2015-03-24T23:29:16 < malinus> Laurenceb_: is the stm on the rocket?
2015-03-24T23:29:29 < Laurenceb_> scummos: yes, defiantly
2015-03-24T23:29:39 < malinus> Really? that's impressive
2015-03-24T23:29:45 < Laurenceb_> BrainDamage: I'd guess ~150km horizontal
2015-03-24T23:29:53 < scummos> do you get enough horizontal speed?
2015-03-24T23:29:58 < Laurenceb_> youd need to scale it up an order of magnitude
2015-03-24T23:30:02 < scummos> to stay in an orbit ;P
2015-03-24T23:30:04 < Laurenceb_> and make it two stage
2015-03-24T23:30:11 < scummos> okay
2015-03-24T23:30:17 < Laurenceb_> but its still doable with balloon launch imo
2015-03-24T23:30:18 < BrainDamage> aw, 150 is too short
2015-03-24T23:30:24 < Laurenceb_> lol what for?
2015-03-24T23:30:25 < malinus> Laurenceb_: do you have all the legal stuff in order?

2015-03-24T23:30:38 < malinus> :D
2015-03-24T23:30:38 < BrainDamage> to deliver payloads to HaD legal location
2015-03-24T23:30:46 < Laurenceb_> I have talked about this with FAA and CAA
2015-03-24T23:30:53 < malinus> And they said?
2015-03-24T23:30:57 < Laurenceb_> US launch is pretty trivial
2015-03-24T23:31:22 < Laurenceb_> there is a standard FAA risk assesment, I completed it and it comes out as "zero hazard"
2015-03-24T23:31:46 < BrainDamage> say, 500g of  PETN and some rudimentary ballistic guidance
2015-03-24T23:31:49 < Laurenceb_> that means less than 10^-6 normalized fatalities per launch iirc :D
2015-03-24T23:31:55 < Laurenceb_> lol BrainDamage
2015-03-24T23:32:06 < scummos> hahaha 10^-6
2015-03-24T23:32:19 < scummos> how does that calculation work?
2015-03-24T23:32:22 < Laurenceb_> its very simple
2015-03-24T23:32:48 < Laurenceb_> we launch above the limit for controlled airspace
2015-03-24T23:32:49 < scummos> "probability of explosion" "numer of people who die when it explodes"
2015-03-24T23:33:05 < Laurenceb_> then launch over an area of closed airspace for it to fall through
2015-03-24T23:33:21 < scummos> ah, I see
2015-03-24T23:33:23 < Laurenceb_> then multiple proabability of it hitting someone on the head by population density
2015-03-24T23:33:56 < Laurenceb_> by fatality probability if it hits someone on the head, which is another assessment procedure
2015-03-24T23:34:06 < scummos> haha
2015-03-24T23:34:11 < malinus> will it kill?
2015-03-24T23:34:12 < Laurenceb_> that gives 0 probability of fatality
2015-03-24T23:34:20 < Laurenceb_> from the mass, velocity etc
2015-03-24T23:34:27 < malinus> Laurenceb_: the parashoot could fail
2015-03-24T23:34:36 < Laurenceb_> so its safe to launch anywhere, providing you follow ATC rules
2015-03-24T23:34:43 < Laurenceb_> malinus: there is no chute
2015-03-24T23:35:03 < malinus> hmm
2015-03-24T23:35:12 < Laurenceb_> after burnout and re entry its a singed 25gram alu tube in freefall
2015-03-24T23:35:25 < Laurenceb_> not hazardous according to FAA
2015-03-24T23:35:34 < scummos> okay that will not kill you even if it hits you on the head
2015-03-24T23:35:39 < scummos> what about the balloon it is launched from?
2015-03-24T23:35:47 < malinus> Laurenceb_: how do you take pictures/data of the flight then :O?

2015-03-24T23:40:17 < Laurenceb_> well it runs off its own battery

2015-03-24T23:42:00 < edmoore> i got iain to climb a rocket once whose motor ignition was controlled only by my software not having detected iain performing an action
2015-03-24T23:42:12 < edmoore> and so if it mis-detected it then it would have launched and probably killed him

2015-03-25T01:21:22 < qyx_> mhm, non-mag jacks are smaller

2015-03-25T01:29:02 < qyx_> order him some $1 passive injector

2015-03-25T04:07:49 < dongs> yep, i think theres no way to do it without via in pad everyfuckingwehre
2015-03-25T04:07:55 < emeb_mac> ya

2015-03-25T14:17:27 < edmoore> Laurenceb, (or anyone) is texane's st-link still the way to use gdb with the discovery boards on nix systems?
2015-03-25T14:17:39 < Laurenceb> it is for me...
2015-03-25T14:17:46 < Laurenceb> but most people use openocd
2015-03-25T14:17:54 < Laurenceb> but the config is annoying
2015-03-25T14:18:04 < Laurenceb> texane is easy to use, but a little glitchy
2015-03-25T14:18:26 < edmoore> the alternative is i just use my black magic probe directly
2015-03-25T14:18:49 < Laurenceb> yeah, i cant make mine work lol
2015-03-25T14:18:50 < edmoore> there's the swd header on there which i presume i can just attach to
2015-03-25T14:18:57 < Laurenceb> i mean, the hardware works fine
2015-03-25T14:19:03 < Laurenceb> but its all weird
2015-03-25T14:19:55 < jpa-> openocd works much better than texane for me nowadays
2015-03-25T14:20:31 < jpa-> you can steal the configs from e.g. here: https://github.com/PetteriAimonen/STM32_Trace_Example/blob/master/Makefile
2015-03-25T14:21:11 < edmoore> great thanks
2015-03-25T14:21:23 < Laurenceb> hmm maybe i should too
2015-03-25T14:22:29 < Laurenceb> https://github.com/PetteriAimonen/STM32_Trace_Example/blob/master/configure-trace.openocd
2015-03-25T14:22:35 < Laurenceb> source [find interface/stlink-v1.cfg]
2015-03-25T14:22:40 < Laurenceb> does that have to be defined too?
2015-03-25T14:23:04 < jpa-> well that file is totally separate and only related to configuring the tracing
2015-03-25T14:23:18 < jpa-> the makefile only has the basic program / debug rules, that file is not necessary for it
2015-03-25T14:27:04 < Laurenceb> ok
2015-03-25T14:27:16 < Laurenceb> its still more complex than texane :D
2015-03-25T14:27:34 < Laurenceb> s/complex/confusing
2015-03-25T14:28:21 < jpa-> yes, more commands and you have to know if you have stlink-v1 or stlink-v2 or something else
2015-03-25T14:28:30 < jpa-> but once you have it working, who cares
2015-03-25T14:28:40 < jpa-> also: RTOS thread support (when it works)

2015-03-25T17:12:20  * Taxman is designing a 5V -> 3.3V power supply for the F4
2015-03-25T17:14:47  * specing watches as Taxman PhD's in 5V->3.3V power supplies
2015-03-25T17:17:22 < Taxman> i need 100µF bulk capacitance at the input. what should i use? tantal polymer or MLCC?
2015-03-25T17:19:26 < edmoore> you need that much?
2015-03-25T17:19:30 < edmoore> that's a lot
2015-03-25T17:19:42 < edmoore> an F4 microcontroller or an F4 phantom jet engine?
2015-03-25T17:21:07 < qyx_> 100uF input? is that some 20kHz '90 switcher?
2015-03-25T17:22:03 < Taxman> no, 2,5 MHz
2015-03-25T17:22:31 < qyx_> which one?
2015-03-25T17:22:37 < Taxman> the problem is a microSD card slot, which creates a high inrush current when a card is inserted
2015-03-25T17:22:51 < Taxman> SC189
2015-03-25T17:23:41 < Taxman> well, 47µF is enough, too
2015-03-25T17:23:49 < qyx_> and your power supply cannot manage that?
2015-03-25T17:24:00 < qyx_> i mean the one supplying the wsitching regulator
2015-03-25T17:24:04 < Taxman> but the price does not differ that much between 100µ and 47µ tantal
2015-03-25T17:24:30 < Taxman> there is a cable between. this is the second pcb within a case
2015-03-25T17:24:40 < qyx_> meh
2015-03-25T17:24:53 < Taxman> and the power goes over a standard 0.14mm^2 industrial data cable
2015-03-25T17:25:20 < qyx_> either a tantal one or ~200uF of mlcc
2015-03-25T17:25:35 < qyx_> they would derate a bit on 5V
2015-03-25T17:25:50 < Taxman> 200µF and 16V or so
2015-03-25T17:25:55 -!- barthess [~barthess@86.57.155.106] has quit [Quit: Leaving.]
2015-03-25T17:26:04 < qyx_> or less, but higher voltage rating/physical size
2015-03-25T17:26:50 < qyx_> you can google some graphs depicting %C change over temp/package/voltage
2015-03-25T17:26:55 < Taxman> the avx TCJB107M006R0070 is nice, but expensive
2015-03-25T17:27:01 < Taxman> tantal polymer
2015-03-25T17:27:31 < Taxman> thanks, i know, the capaticance decrease of MLCC is hugh
2015-03-25T17:27:33 < qyx_> i would go for 10V
2015-03-25T17:27:34 < Taxman> huge
2015-03-25T17:27:43 < qyx_> 6.3V is a bit meh for 5V
2015-03-25T17:28:00 < Taxman> the avx fae tole me, 25% margin is enough for tantal polymer
2015-03-25T17:28:04 < qyx_> tantals like to explode on overvoltage
2015-03-25T17:28:19 < qyx_> mhm, ok then
2015-03-25T17:28:28 < Taxman> yeah, the polymers, too?
2015-03-25T17:29:11 < Taxman> the murata GRM32ER61A107ME20L is a 100 10V mlcc where 47µ are remaining at 5V
2015-03-25T17:29:11 < qyx_> i don't know for polymers actually
2015-03-25T17:29:38 < Taxman> it is a bit cheaper than the tantal
2015-03-25T17:31:47 < Taxman> a small electrolytic one would be an option, too, but i can't find types with more than 2000 hours in a small smd package
2015-03-25T17:34:35 < Taxman> and for the mps fans in here: has one used already the MP2161?
2015-03-25T17:37:35 < Taxman> it has a COT regulator, and i have no experiences how fast it reacts to load transients

2015-03-26T11:50:22 < zyp> M2 can carry x4, IIRC
2015-03-26T11:50:23 < qyx_> so they must be available even at farnell

2015-03-26T11:53:58 < qyx_> and M2 are cool, they are even cheaper but require 0.8mm or 1mm pcb thickness, i don't remember exactly

2015-03-26T11:58:51 < dongs> that shit needs 1mm pcb
2015-03-26T11:59:02 < dongs> i just wanna abuse it to make a L-shaped mounting of boards

2015-03-26T11:59:16 < dongs> but i really dont wanna use DIP socket
2015-03-26T12:00:37 < dongs> anythign else thats similar, at least 34 pins?
2015-03-26T12:00:42 < dongs> that I can just plug PCB edge into
2015-03-26T12:00:56 < dongs> and qyx how were you gonna abuse it

2015-03-26T16:31:35 < Steffanx> wouldn't be surprised he will tell you he uses X pF, not because the datasheet tells it, but because it works :)
2015-03-26T16:32:23 < zyp> yeah, I'm just waiting for that reply :p

2015-03-26T17:03:23 < yan_> have a firmware arch question: i am planning on using queues (freertos) to synchronize messages of up to 32 bytes in length that are received/sent via a spi bus, approx 100-200/second. I am trying to decide whether to create a pool of memory for mesages (6-8, since the consumer shouldn't lag much behind the producer)  and just pass pointers down the queues, or to pass the 32 byte messages by value and let the queue itself contain them.. the latter would greatly si
2015-03-26T17:03:44 < yan_> this will be running on a stm32l1xx series clocked at about 24mhz
2015-03-26T17:04:00 < jpa-> your first line was cut of at ... greatly si
2015-03-26T17:04:23 < yan_> '... the latter would greatly simplify memory management, but is it considered bad practice to pass around values greater than an ordinal type'
2015-03-26T17:04:53 < jpa-> queue will mean 2x extra copies, i.e. 50-100 cycles per message; if you have less than 10 000 messages per second, that is probably nothing to worry about
2015-03-26T17:05:35 < jpa-> bad practices are only guidelines anyway; more bad designs are made by blindly following "good practices", than by ignoring them after analysis
2015-03-26T17:05:38 < yan_> jpa-: my hunch was to do it by value, and only optimize if i notice it being insufficient
2015-03-26T17:05:51 < jpa-> yep, should work
2015-03-26T17:06:04 < Getty> weeks of work can easily replace hours of planning
2015-03-26T17:07:30 < jpa-> i've spent way too much debugging bugs in code that should never have existed

2015-03-26T17:15:31 < dongs> zyp, to answer your q, i dont know. i used 12pf on the rtc
2015-03-26T17:15:42 < dongs> and 12pf on the 2520
2015-03-26T17:15:47 < dongs> but that was just copypaste from nrf shite
2015-03-26T17:15:51 < zyp> hmm
2015-03-26T17:15:54 < dongs> 12pf for rtc should be accurate at least
2015-03-26T17:16:11 < dongs> i generally use 18pf for everything else 12-27mhz
2015-03-26T17:17:38 < zyp> I once got it wrong enough to matter, so I tend to be careful about it now
2015-03-26T17:20:37 < zyp> but ok, I'll put 18p, that's probably fine
2015-03-26T17:20:51 < dongs> why not just use 12p for both
2015-03-26T17:22:05 < zyp> because 25MHz crystals generally have higher load capacitance than the RTC crystal
2015-03-26T17:22:11 < dongs> o
2015-03-26T17:22:43 < gxti> real pro EEs actually look at the datasheet and stuff
2015-03-26T17:23:45 < zyp> okay, only supercap charge limiting resistor left
2015-03-26T17:23:48 < gxti> or not even that, you can get the load capacitance figure from the digikey listing if you're lazy
2015-03-26T17:23:52 < zyp> wonder how fast I can charge it
2015-03-26T17:23:59 < gxti> CL -> multiply by 2 and subtract 5 -> done
2015-03-26T17:24:15 < zyp> yeah, as long as you know CL for the actual part used
2015-03-26T17:25:33 < trepidaciousMBR> Never look at the datasheet when you can do it arduino-style and just guess or make something up ;)
2015-03-26T17:25:48 < trepidaciousMBR> If it works once, it's basically completely right and will work forever - ship it!
2015-03-26T17:25:59 < gxti> yes yes very witty
2015-03-26T17:27:04 < jpa-> looking at the datasheet doesn't really help when you don't know the part number

2015-03-26T21:11:15 < jadew> edmoore, the nokia app doesn't need a data connection

2015-03-26T21:11:42 < edmoore> nice
2015-03-26T21:11:48 < jadew> it still uses data for some stuff tho, but it's optional

2015-03-26T21:12:02 < edmoore> might consider that next time
2015-03-26T21:12:03 < jadew> and the voice is a british chick
2015-03-26T21:12:07 < jadew> so it's also hot

2015-03-26T22:06:28 < scummos> python
2015-03-26T22:06:29 < scummos> sorry
2015-03-26T22:06:31 < gxti> python
2015-03-26T22:06:35 < scummos> I typed it before I read your message
2015-03-26T22:06:45 < kekman> *rage*
2015-03-26T22:06:51 < scummos> why? python does all these
2015-03-26T22:06:52 < scummos> :D
2015-03-26T22:09:29 < zyp> doesn't most hex editors have conversion shit like that?
2015-03-26T22:10:13 < zyp> I tend to just use python myself though :D
2015-03-26T22:10:50 < kekman> how to get python output hex or bin?
2015-03-26T22:11:18 < kekman> bin
2015-03-26T22:11:20 < kekman> ()
2015-03-26T22:11:32 < kekman> hex()
2015-03-26T22:11:40 < kekman> ok this is goode
2015-03-26T22:12:52 < scummos> good that you noticed
2015-03-26T22:12:54 < scummos> :D
2015-03-26T22:13:21 < zyp> and then you have .encode('hex') and .decode('hex') for converting from/to ascii
2015-03-26T22:13:53 < zyp> and int(…, 16)
2015-03-26T22:14:03 < zyp> or whatever other radix you'd like
2015-03-26T22:21:15 < scummos> also 0x and 0b literals
2015-03-26T22:21:57 < jadew> strtol IIRC in C
2015-03-26T22:22:43 < jadew> why is everyone using python so much?
2015-03-26T22:22:48 < scummos> yes, clearly use a c interpreter instead
2015-03-26T22:23:05 < jadew> didn't meant that
2015-03-26T22:23:13 < jadew> out of context question
2015-03-26T22:23:18 < jadew> since everyone seems to enjoy it
2015-03-26T22:23:22 < BrainDamage> if you're on lunix, qalculate is quite good
2015-03-26T22:23:31 < BrainDamage> it handles all that + much more
2015-03-26T22:23:48 < BrainDamage> including physical units, and plenty of builtin functions
2015-03-26T22:24:11 < jadew> oh, right and if you're on windows, calc can do that too
2015-03-26T22:24:55 < jadew> http://dumb.ro/screenshot/qiejE.png
2015-03-26T22:26:15 < gxti> why python? because it's easy to learn but quite nicely designed at the core
2015-03-26T22:26:36 < scummos> also there's numpy
2015-03-26T22:27:36 < jadew> I guess I should get over the syntax and spend a day or two to get familiar with it
2015-03-26T22:27:43 < gxti> and easy to keep learning because it's self-consistent. absolutely everything is an object, and extending the language works the same as how the core does.
2015-03-26T22:28:01 < jadew> oh man... I almost threw up in my mouth
2015-03-26T22:28:16 < jadew> languages that force everything to be an object are stupid
2015-03-26T22:28:22 < gxti> u wot m8
2015-03-26T22:28:53 < jadew> can you have stand alone procedures?
2015-03-26T22:29:05 < gxti> yes.
2015-03-26T22:29:18 < jadew> in a library?
2015-03-26T22:29:21 < gxti> "everything is an object" not "you have to put all your code in classes i.e. java"
2015-03-26T22:29:44 < jadew> so why is everything an object then?
2015-03-26T22:30:19 < gxti> like functions are objects, so you can pass them as parameters to other functions
2015-03-26T22:30:28 < jadew> ah, got it
2015-03-26T22:31:03 < jadew> I wrote a language some years back that had some really neat features regarding callbacks
2015-03-26T22:31:16 < jadew> you could pass a callback with specific parameters as default
2015-03-26T22:31:48 < jadew> given f(a, b, c) you could pass it as @f(c: 10)
2015-03-26T22:32:32 < gxti> functools.partial does that in python.
2015-03-26T22:32:49 < jadew> interesting
2015-03-26T22:32:53 < jadew> I'll check it out
2015-03-26T22:33:09 < scummos> functions are objects too
2015-03-26T22:33:24 < scummos> "everything is an object" is the only sane approach to object-orientation imo
2015-03-26T22:33:32 < scummos> and python does it really well mostly
2015-03-26T22:33:40 < jadew> not everything is object oriented
2015-03-26T22:33:51 < gxti> well, it's the ideal way but it's not practical to do something at the level of c++ like that
2015-03-26T22:34:04 < jadew> some things just use objects, they don't have to be objects themselves
2015-03-26T22:34:24 < scummos> it makes a lot of things quite elegant to have everything be an object
2015-03-26T22:34:31 < jadew> also, I'm not sure how functions are objects, but if they instead are functors by default, then that's stupid too
2015-03-26T22:34:38 < jadew> if they're not, then they're not objects
2015-03-26T22:35:23 < gxti> not in a mathematical sense maybe, but who cares
2015-03-26T22:36:00 < jadew> for the record, in an interpreted language, everything is an object in how it's implemented
2015-03-26T22:36:11 < jadew> any chance they're refering to that?
2015-03-26T22:36:38 < jadew> but that's kinda irrelevant, all that matters is how it's presented to you
2015-03-26T22:37:14 < gxti> it means that a variable can hold a scalar, a list, a function, a class, a module, an exception, a stack frame, or literally anything else that's part of the language.
2015-03-26T22:38:07 < gxti> in terms of the core C implementation it's a pointer to a struct that has a type and a set of attributes.
2015-03-26T22:38:18 < jadew> that doesn't make it an object tho
2015-03-26T22:38:26 < jadew> the implementation is irrelevant
2015-03-26T22:38:27 < gxti> depends on the definition of 'object'.
2015-03-26T22:38:38 < jadew> can you do $x = 10; $x-
2015-03-26T22:38:42 < jadew> can you do $x = 10; $x->whatever();
2015-03-26T22:39:03 < jadew> if you can, it's an object
2015-03-26T22:39:06 < jadew> if you can't, it's not
2015-03-26T22:39:28 < gxti> yes
2015-03-26T22:39:34 < jadew> yes, you can?
2015-03-26T22:39:40 < gxti> x = 1; x.__add__(2) works
2015-03-26T22:39:44 < jadew> got it
2015-03-26T22:39:45 < Getty> wait wait
2015-03-26T22:39:49 < jadew> same goes for functions?
2015-03-26T22:39:50 < Getty> you are still discussing it?
2015-03-26T22:40:01 < gxti> Getty: got anything better to talk about

2015-03-26T22:40:10 < gxti> jadew: yes, functions have attributes
2015-03-26T22:40:14 < Getty> yeah no do you still need to convert hex/bin stuff?
2015-03-26T22:40:21 < Getty> whoever wanted to know it
2015-03-26T22:40:34 < gxti> jadew: and methods are just a type of attribute that is callable, by the way
2015-03-26T22:41:22 < jadew> I'll check it out, sounds interesting

2015-03-26T22:46:13 < jadew> I agree, PHP is garbage
2015-03-26T22:46:54 < jadew> javascript is okish for scripting but it sucks in some regards
2015-03-26T22:47:17 < Steffanx>  but it gets the job done :P

2015-03-26T22:47:48 < jadew> what trashtalk?
2015-03-26T22:47:56 < Fleck> superbia: craptalk is common in this channel, sadly!
2015-03-26T22:48:09 < Steffanx> and i see jadew uses it too for his website :P

2015-03-26T22:53:11 < Steffanx> don't know haven't seen him for a while
2015-03-26T22:53:14 < superbia> who is dongs
2015-03-26T22:53:30 < Steffanx> [NickServ] Last seen  : now <= he's there, somewhere
2015-03-26T22:55:12 < superbia> i am going to write a book

2015-03-26T22:56:12 < jadew> "the troll from under the #"
2015-03-26T22:58:23 < kekman> if you have macro defines with multiple values in them
2015-03-26T22:58:35 < kekman> do you use some python bitfield trick`?
2015-03-26T22:59:00 < jadew> I think that's wasteful in interpreted languages
2015-03-26T22:59:14 < jadew> it only makes sense in compiled ones since that stuff can be optimized out
2015-03-26T22:59:28 < jadew> (if you're thinking about configuration flags)
2015-03-26T22:59:37 < kekman> doing bits from x to y by hand is prone to errors
2015-03-26T23:00:00 < jadew> it would probably be more efficient to just use separate variables for each thing
2015-03-26T23:00:11 < kekman> wait
2015-03-26T23:00:17 < kekman> in C actually
2015-03-26T23:00:20 < qyx_> what are you trying to achieve?
2015-03-26T23:00:25 < kekman> bitshifting and
2015-03-26T23:00:31 < kekman> or
2015-03-26T23:00:31 < qyx_> with python?
2015-03-26T23:00:43 < kekman> single hexadecimal value
2015-03-26T23:01:19 < kekman> nothing mate bitshift and OR is the way. always
2015-03-26T23:01:43 < kekman> and you also see what is happening
2015-03-26T23:01:55 < kekman> not just hexcrypt
2015-03-26T23:02:40 < Steffanx> lol, can you repeat that kekman? :D
2015-03-26T23:03:18 < kekman> I'm doing chip initialisation code and I need to set register stuff
2015-03-26T23:03:21 < qyx_> i don't understand you but thats probably because of my engrish
2015-03-26T23:03:31 < qyx_> so just set it
2015-03-26T23:03:55 < qyx_> like register |= (1 << BIT);
2015-03-26T23:04:09 < superbia> its not gay enough
2015-03-26T23:05:23 < kekman> just that example had all as single hex but what benefits it actually has
2015-03-26T23:07:44 < zyp> I used to write hex values by hand before, my old code looks pretty unreadable compared to the one I'm writing nowadays :p
2015-03-26T23:08:19 < malinus> zyp: lol
2015-03-26T23:08:22 < superbia> can i see it
2015-03-26T23:08:26 < emeb> zyp: what do you do instead of hex now?
2015-03-26T23:08:44 < zyp> (1 << 5) | (1 << 3)
2015-03-26T23:08:58 < Fleck> ;)
2015-03-26T23:09:02 < zyp> often with a comment afterwards naming the bits
2015-03-26T23:09:15 < emeb> better
2015-03-26T23:09:31 < emeb> any reason not to use the reg/bit defs in stm32fxxx.h?
2015-03-26T23:09:33 < kekman> how about doind 0b00000000000000000000000000000001
2015-03-26T23:09:47 < zyp> yes, that's more maintainable than 0x24
2015-03-26T23:09:59 < zyp> 0x28 actually
2015-03-26T23:10:31 < zyp> well
2015-03-26T23:10:33 < gxti> counting bits sucks
2015-03-26T23:10:38 < zyp> I like my C++ register defs
2015-03-26T23:10:43 < superbia> i think you need to get laid
2015-03-26T23:10:46 < zyp> and I'm too lazy to do bit defs
2015-03-26T23:10:58 < kekman> mixed hex, bin and bitshifted integer would be the way
2015-03-26T23:11:00 < zyp> superbia, who?
2015-03-26T23:11:14 < superbia> like all of dicked people inhere

2015-03-27T00:07:18 < MrCircuitMatt> I then initialize the I2C with HAL_I2C_Init() and try to send stuff, but it's just not making it out of the pin

2015-03-27T00:09:02 < zyp> if you're interested in an alternative, you might want to take a look at libopencm3
2015-03-27T00:10:11 < MrCircuitMatt> zyp: well if I could I'd use no library at all, but I thought since things are a bit inter-mingled and not straight-forward for a beginner I'd take the top-down approach

2015-03-27T00:13:48 < zyp> okay, first of all, you said you turned on the GPIO clock, did you also set the pins to AF mode and opendrain, and select the right AF?
2015-03-27T00:14:19 < MrCircuitMatt> yes
2015-03-27T00:14:19 < zyp> that should be everything required on the GPIO side of it

2015-03-27T00:15:35 < MrCircuitMatt> zyp: I understand you're not familiar with the library but this is how I do it, maybe there is something wrong with those constants or I failed to understand the datasheet: http://pastebin.com/aeiVKZVB
2015-03-27T00:15:37 < zyp> you're certain that the pins remain high, you don't even see a start condition?
2015-03-27T00:16:25 < zyp> okay, that looks right to me

2015-03-27T00:20:10 < MrCircuitMatt> I don't think I'm seeing a start condition
2015-03-27T00:20:30 < MrCircuitMatt> zyp: when I program both pins go low, but I have the impression that this is when I start programming
2015-03-27T00:20:58 < zyp> when you program, both pins are floating
2015-03-27T00:21:13 < zyp> so that's natural

2015-03-27T00:22:26 < zyp> you should probably set a breakpoint after initializing I2C and check the registers
2015-03-27T00:22:39 < zyp> then set another breakpoint after reading or writing and check again
2015-03-27T00:23:47 < MrCircuitMatt> OK I think I have set it up that I can do this, with openocd and gdb and the remote stuff
2015-03-27T00:24:12 < MrCircuitMatt> zyp: by the way the I2C peripherial "finds" the proper output pins by checking which ones are set to that alternate mode?
2015-03-27T00:24:14 < zyp> say, are you certain that the functions you're using are actually doing a full read/write transaction, not just the act of transferring data to/from the data register?
2015-03-27T00:24:19 < zyp> yes
2015-03-27T00:24:19 < MrCircuitMatt> there is no hidden magic there that could go wrong?
2015-03-27T00:24:25 < MrCircuitMatt> OK
2015-03-27T00:24:42 < MrCircuitMatt> checking
2015-03-27T00:26:35 < MrCircuitMatt> zyp: the function that I'm using does write stuff to the DR register and then waits until some flags get cleared, presumably indicating that the operation has happened
2015-03-27T00:26:55 < zyp> can you pastebin it?
2015-03-27T00:27:53 < MrCircuitMatt> zyp: http://pastebin.com/b5BDp93r
2015-03-27T00:28:15 < MrCircuitMatt> it does look like a full transaction to me
2015-03-27T00:28:46 < zyp> yeah, it does
2015-03-27T00:29:03 < MrCircuitMatt> I have to say that I have nothing hooked up to the bus
2015-03-27T00:29:11 < MrCircuitMatt> so the transaction should fail indeed
2015-03-27T00:29:14 < MrCircuitMatt> but I should still see it
2015-03-27T00:29:25 < zyp> how are you checking it?
2015-03-27T00:29:37 < MrCircuitMatt> I have a scope hooked up to the bus
2015-03-27T00:29:48 < MrCircuitMatt> and this is after the LA showed nothing
2015-03-27T00:30:09 < zyp> hmm, okay
2015-03-27T00:30:09 < MrCircuitMatt> and I'm single-shot-triggering on a falling edge of the clock line
2015-03-27T00:30:37 < MrCircuitMatt> I mean I should at least see the start condition
2015-03-27T00:30:42 < zyp> check the return code of that function?
2015-03-27T00:30:44 < MrCircuitMatt> and in fact also the slave address...
2015-03-27T00:30:50 < MrCircuitMatt> the function returns clean
2015-03-27T00:31:07 < MrCircuitMatt> no wait sorry the init that I didn't show you returns clean
2015-03-27T00:31:13 < MrCircuitMatt> this one returns with the BUSY error
2015-03-27T00:31:22 < zyp> okay

2015-03-27T00:31:56 < zyp> or 94
2015-03-27T00:32:48 < MrCircuitMatt> hm right didn't even see that one
2015-03-27T00:33:03 < MrCircuitMatt> zyp: I can stick a breakpoint in there if that helps
2015-03-27T00:33:09 < zyp> hmm, looks weird
2015-03-27T00:33:23 < zyp> yeah, check which of the conditions it fails on
2015-03-27T00:33:36 < zyp> either way, both fails before it sends start condition, so that explains it
2015-03-27T00:33:40 < MrCircuitMatt> I'm sure it's failing because of a rookie mistake on my side :(

2015-03-27T00:38:49 < zyp> set a breakpoint on the function entry
2015-03-27T00:38:55 < zyp> then single step through it
2015-03-27T00:39:20 < MrCircuitMatt> yeah that's what I tried

2015-03-27T00:39:32 < MrCircuitMatt> I sure hope so... let me check
2015-03-27T00:39:46 < zyp> well, I guess you wouldn't be able to set the breakpoint if not
2015-03-27T00:42:14 < MrCircuitMatt> yeah
2015-03-27T00:42:31 < MrCircuitMatt> so I recompiled with -ggdb instead of -g, let's see

2015-03-27T00:48:50 < zyp> because I suspect you have a timing related issue, your code is so fast that you're trying to start a transaction right after configuring the gpios, before the pullups have had enough time to actually pull the signals high

2015-03-27T01:05:24 < zyp> what you see is still consistent with my «too fast» theory
2015-03-27T01:06:04 < zyp> also, you shouldn't really rely on the internal pullups for i2c, they are rather weak
2015-03-27T01:06:13 < zyp> and with external pullups, this problem wouldn't exist
2015-03-27T01:06:46 < MrCircuitMatt> I added 500 ms
2015-03-27T01:07:30 < MrCircuitMatt> so I have init gpio; 500 ms; init i2c; 500 ms; while(1) {transfer; 500 ms;}
2015-03-27T01:07:34 < zyp> hmm, does your init function touch the SWRST bit in CR1? if not you're probably supposed to call a separate reset function before calling the init

2015-03-27T02:23:46 < dongs> its gonna get arrayed
2015-03-27T02:23:51 < dongs> so y our paste layer wont get used anyway

2015-03-27T02:26:05 < zyp> yeah
2015-03-27T02:26:39 < zyp> they should be at ~12-14V, then there's some at 5V and the rest are all 3.3V
2015-03-27T02:26:55 < zyp> but higher are good because of derating and shit
2015-03-27T02:27:17 < dongs> ok. most of my stuff is 6.3V-16V for <10uF and 50V for pF stuff
2015-03-27T02:27:36 < dongs> wait wat
2015-03-27T02:27:38 < dongs> 22uF 06034

2015-03-27T02:29:58 < Simon--> ah
2015-03-27T02:34:01 < zyp> hmm, I see I forgot to specify U5/U6, those should both be 3.3V regs

2015-03-27T02:38:52 < qyx_> probably 22uF 0603 is about the same as 10uF 0805

2015-03-27T02:44:23 < zyp> wat
2015-03-27T02:44:40 < zyp> origin should be bottom left, and it should be way taller than it's wide
2015-03-27T02:44:44 < zyp> hang on, let me check the file

2015-03-27T10:07:22 < zyp> when I said I'll pay for 1k, $300 is what I had in mind

2015-03-27T10:46:57 < zyp> yeah, I rented one of these last time: http://www.globaladvancedcomm.com/pocketwifi.html
2015-03-27T10:47:58 < zyp> before I've just rented a japanese simcard, but that shit were cheaper and since I were travelling alone last time I didn't really need the ability to call anybody
2015-03-27T10:48:46 < Laurenceb_> cuz you have no friends
2015-03-27T10:49:27 < dongs> zyp, but that was a jap thing
2015-03-27T10:49:32 < dongs> i was asking if euroband shit would work
2015-03-27T10:49:55 < zyp> Laurenceb_, oh, I have plenty of friends, just none that had time to spontaneously take a two week vacation in jp
2015-03-27T10:49:59 < dongs> is dat some wimax trash
2015-03-27T10:50:02 < dongs> 165mbps
2015-03-27T10:50:11 < zyp> no, I think it's LTE
2015-03-27T10:50:19 < dongs> then they're full of shit
2015-03-27T10:50:26 < zyp> and fwiw, my european phone works fine in jp
2015-03-27T10:50:44 < dongs> LTE or 3G?
2015-03-27T10:50:51 < zyp> 3G
2015-03-27T10:51:28 < dongs> wonder if that was covered by 2100mhz band
2015-03-27T10:51:28 < zyp> still using nexus 4
2015-03-27T10:51:47 < zyp> I don't think my friends with nexus 5 and other shit with LTE had any problems either
2015-03-27T10:55:05 < dongs> http://www.ebay.com/itm/221722304717 so you think this will work with rageberrypi?
2015-03-27T10:55:42 < zyp> looks like norwegian LTE is mainly 2600mhz and some 1800mhz
2015-03-27T10:55:55 < PaulFertser> dongs: btw, 3G is not really a standard for communications, it's a standard mandating minimal throughput etc. GSM EDGE and DECT are technically 3G too.
2015-03-27T10:56:23 < zyp> PaulFertser, just like HSPA is 4G? :p
2015-03-27T10:58:39 < dongs> i guess ill blow 10 bucks on it
2015-03-27T10:58:39 < dongs> and find out
2015-03-27T10:59:01 < dongs> that guys feedback is stellar
2015-03-27T10:59:25 < dongs> maybe its locked to chinatel or something

2015-03-27T12:34:34 < zyp> oh, regarding board qty, since there's three boards per panel I guess you might as well assemble 12
2015-03-27T12:34:50 < dongs> right
2015-03-27T12:35:02 < dongs> that wasnt even gonna up for  discussion :)

2015-03-27T12:36:14 < dongs> ¥169 rage yen
2015-03-27T12:36:36 < zyp> 1.34 at digikey, so it's actually cheaper from mouser even

2015-03-27T12:36:58 < dongs> but probly not cheaper at dk either
2015-03-27T12:38:15 < zyp> the difference is pretty irrelevant considering shipping will be more than the chips

2015-03-27T12:49:38 < Getty> told my dad bold "hey, i know how i would program it in C, i just dont know how you can do it in BASCOM" he replied: "yeah, hey, then why you dont do it yourself directly? then i have more time for the rest"
2015-03-27T12:52:07 < Laurenceb> heh BASCOM
2015-03-27T12:52:14 < Getty> yeah ;)
2015-03-27T12:52:50 < Getty> i mean, we cant actually talk bad about him in this case, when he started doing BASCOM there were probably not many options to choose from
2015-03-27T12:53:02 < Laurenceb> yeah
2015-03-27T12:53:08 < Laurenceb> i used bascom in 2005
2015-03-27T12:54:21 < zyp> I used C on AVR in 2005
2015-03-27T12:54:43 < Getty> yeah well, i dont talk about 2005 ;-)
2015-03-27T12:54:46 < Getty> hhehehehehe
2015-03-27T12:54:53 < zyp> were you even born then?
2015-03-27T12:55:34 < malinus> Daily reminder that humans born in 2005 can actually speak now.
2015-03-27T12:55:45 < malinus> JustScaryStuff.png
2015-03-27T12:58:11 < zyp> uh, learning to speak doesn't take that long
2015-03-27T12:58:27 < zyp> I would expect a fair amount of humans born in 2010 to be able to read now
2015-03-27T12:58:32 < Getty> well, not all of them probably ;-)
2015-03-27T12:58:45 < Getty> about the speaking
2015-03-27T12:59:37 < zyp> actually, when do people generally learn how to read?
2015-03-27T13:00:36 < zyp> I remember I read an article a while back, about parents feeling pressured to teach their kids to read before they started school
2015-03-27T13:00:41 < Getty> i just remember when i learned to code and LOAD"$",8
2015-03-27T13:00:56 < Getty> does that count as "reading"? ;)
2015-03-27T13:01:23 < zyp> and that sounded pretty weird to me, since I learned to read when I was 4
2015-03-27T13:01:46 < Getty> yeah i had a C64 at that time already
2015-03-27T13:02:02 < Getty> \o/ and a nerd was born
2015-03-27T13:02:06 < zyp> I mean, even if all kids doesn't learn how to read when they are 4, you'd expect them to at least be able to when they are 6?
2015-03-27T13:02:47 < Getty> its probably a motivating thing, these days kids will learn to read early through using of mobile phones, but in previous years... parents didnt pushed them.... dont know
2015-03-27T13:03:17 < zyp> we didn't have smartphones in my time :p
2015-03-27T13:03:43 < Getty> yeah thats what i mean ;) i also could imagine, without a computer i might have not read so early
2015-03-27T13:04:01 < Getty> but who knows what i would have done in those 16 hours a day else ;-)

2015-03-27T13:04:48 < zyp> I don't think I had a computer before I were 6
2015-03-27T13:05:20 < Getty> my dad is electronican, he made robots arm at that time, of course he bought his son a computer before it made any sense ;)
2015-03-27T13:05:37 < zyp> but I remember my grandpa had one, that was the best part of the yearly visit
2015-03-27T13:05:41 < Getty> i do remember that he loaded the games for me previously, till i copied his movements
2015-03-27T13:06:11 < zyp> I liked my grandpa's password policy
2015-03-27T13:06:18 < zyp> username: p, password: p
2015-03-27T13:06:29 < zyp> «because that's the closest letter to the enter button»
2015-03-27T13:06:37 < Getty> he had a password login? ;)
2015-03-27T13:06:53 < zyp> to some database stuff he had
2015-03-27T13:06:57 < Getty> ah ok
2015-03-27T13:07:14 < Getty> i just remember that at this time, without Windows for WOrkgroups you actually didnt had a login anywhere
2015-03-27T13:07:18 < Getty> ;)
2015-03-27T13:08:08 < zyp> he did a bunch of genealogy stuff, in some dos-based database system
2015-03-27T13:08:28 < zyp> on windows 3.1
2015-03-27T13:08:31 < Getty> that sounds awesome cool
2015-03-27T13:08:34 < Getty> dont you have the old data?
2015-03-27T13:09:33 < zyp> I believe I do have a copy on a disc somewhere, and I know some other relatives also do
2015-03-27T13:10:49 < zyp> he also made a book out of the data, my mom got one of those

2015-03-27T13:15:08 < Getty> nice would be probably a backup of his system, to see what software he used overall, a "state of time"
2015-03-27T13:15:42 < zyp> heh
2015-03-27T13:15:43 < Getty> a real "digital picture" of a computer in time....
2015-03-27T13:15:59 < zyp> I think he got a windows version of the database software in the later years
2015-03-27T13:16:15 < zyp> so that's probably what I have a copy of
2015-03-27T13:16:28 < Getty> as i didnt had much contact with other people before the windows 3.1 conquer, i am often curious how people used the stuff before
2015-03-27T13:16:40 < Getty> the world pre windows 3.x and pre DOS 5.x was for sure very interesting

2015-03-27T23:04:28 < MrCircuitMatt> zyp: I went ahead and re-did the whole clocking stuff and the I2C stuff without the librar
2015-03-27T23:04:29 < MrCircuitMatt> y
2015-03-27T23:05:15 < MrCircuitMatt> zyp: The good news is that now I'm starting to see how this all hangs together. Tha bad news is that it still does not work. I am getting the start condition though, but the line remains low and I don't get the address on the bus :(
2015-03-27T23:05:31 < MrCircuitMatt> zyp: https://gist.github.com/mweyland/e05b6769c0e50acceaca if you are in the mood for a peek
2015-03-27T23:18:49 < zyp> did you write MODIFY_REG_BITS?
2015-03-27T23:19:07 < zyp> and if so, are you sure it does what you expect?
2015-03-27T23:21:01 < MrCircuitMatt> zyp: good point, I did write it yes
2015-03-27T23:21:23 < MrCircuitMatt> #define MODIFY_REG_BITS(reg, clear, set) MODIFY_REG(reg, clear, ((set) << POSITION_VAL(clear)))
2015-03-27T23:21:58 < zyp> uh, what does MODIFY_REG do?
2015-03-27T23:22:51 < MrCircuitMatt> macros all the way down I guess, that was part of the header file
2015-03-27T23:24:16 < MrCircuitMatt> I'll dig out that definition, one sec. Essentially it takes the register, a mask and some value, and replaces that part of the register specified by the mask with the value
2015-03-27T23:24:24 < MrCircuitMatt> #define MODIFY_REG(REG, CLEARMASK, SETMASK)  WRITE_REG((REG), (((READ_REG(REG)) & (~(CLEARMASK))) | (SETMASK)))
2015-03-27T23:25:02 < zyp> ugh :p
2015-03-27T23:25:27 < MrCircuitMatt> from stm32f4xx.h
2015-03-27T23:27:10 < MrCircuitMatt> also from there: #define POSITION_VAL(VAL)     (__CLZ(__RBIT(VAL)))
2015-03-27T23:28:19 < zyp> oh, right
2015-03-27T23:28:26 < qyx_> wut
2015-03-27T23:28:33 < zyp> cute trick
2015-03-27T23:29:49 < MrCircuitMatt> zyp: I'm not really sure how I'm supposed to use the registers in the form they are given in the header file so I cooked up that MODIFY_REG_BITS macro
2015-03-27T23:30:10 < zyp> I have no idea how they're given in the header file, as I don't use it
2015-03-27T23:31:23 < MrCircuitMatt> just the mask and the bits

2015-03-27T23:31:32 < MrCircuitMatt> I'm concerned that I messed up TRISE, CCR or FREQ
2015-03-27T23:32:20 < zyp> why are you doing the math by hand instead of making the compiler do it for you?
2015-03-27T23:32:47 < zyp> also, what chip is this? why is APB1 running at 25MHz?
2015-03-27T23:34:18 < MrCircuitMatt> OK chip is STM32F411. It's running at 25 MHz because there is a limit (I think 42 MHz) and an example I found online actually exceeded that limit. So I cut it down. The internal oscillator is running at 16 MHz, I use the PLL to push that to 100 MHz and divide this by 4 to get the 25 MHz
2015-03-27T23:34:52 < zyp> uh, weird
2015-03-27T23:34:56 < MrCircuitMatt> and I could just as well have the compiler do the math, but at this stage this would increase the risk of introducing bugs without helping me much
2015-03-27T23:35:04 < MrCircuitMatt> zyp: 25 MHz is not a good frequency?
2015-03-27T23:35:08 < qyx_> is the limit 42MHz for F411?
2015-03-27T23:35:15 < zyp> 84 IIRC
2015-03-27T23:35:22 < zyp> I think it's half as fast as a F407
2015-03-27T23:35:34 < MrCircuitMatt> I thought I could set it to anything I want as long as I respect the datasheet
2015-03-27T23:35:42 < qyx_> yes, you can
2015-03-27T23:35:54 < zyp> yes, unless you need to feed specific clocks into other stuff
2015-03-27T23:36:02 < zyp> like usb, which requires a 48 MHz clock
2015-03-27T23:36:19 < zyp> which in practice means that your sysclk needs to be divisible by 24
2015-03-27T23:36:27 < zyp> (on F407)

2015-03-27T23:37:47 < zyp> http://cgit.jvnv.net/laks/tree/i2c/i2c.cpp#n93 <- this is what I do
2015-03-27T23:37:58 < zyp> clk in that code refers to the specific bus clock
2015-03-27T23:37:59 < MrCircuitMatt> and I have it running at 100 MHz... maybe this is messing up things, I'll fix that
2015-03-27T23:39:00 < MrCircuitMatt> zyp: so clk is in Hz, and that would be 25 MHz in my case?
2015-03-27T23:40:02 < zyp> no, clk is Hz
2015-03-27T23:40:09 < zyp> ah, yeah

2015-03-27T23:41:40 < MrCircuitMatt> zyp: what's your I2C clock rate?
2015-03-27T23:41:52 < zyp> 100000
2015-03-27T23:43:02 < zyp> I haven't touched that code in years, so I'm not sure how sane it is, but it worked last time I used it
2015-03-27T23:43:38 < MrCircuitMatt> hehe OK
2015-03-27T23:44:37 < emeb> that USB clock business makes me wonder how useful the higher speeds on the F42x/F43x are in practice.
2015-03-27T23:44:55 < emeb> or the upcoming F7xx parts.

2015-03-27T23:49:34 < zyp> emeb, not useful at all, you can't run F429 at 180 MHz and still use internal USB PHY
2015-03-27T23:49:54 < zyp> when you use ULPI, I think it doesn't matter

2015-03-28T03:13:46 < qyx_> looks like windows dll name from 1990
2015-03-28T03:13:48 < dongs> oh some kinda hardware multiplier
2015-03-28T03:13:57 < dongs> no its the shit in the msp430/432
2015-03-28T03:14:00 < dongs> https://github.com/energia/Energia/blob/master/hardware/msp430/libraries/DriverLib/utility/mpy32.c
2015-03-28T03:14:49 < dongs> Communication: Up to 4 I2C, 8 SPI, 4 UART
2015-03-28T03:14:50 < karlp> ergia is different
2015-03-28T03:14:50 < dongs> 8 spi is nice
2015-03-28T03:14:55 < dongs> karlp: its same
2015-03-28T03:15:01 < karlp> energia is the arduio ui for msp430/432
2015-03-28T03:15:05 < dongs> right
2015-03-28T03:15:14 < dongs> point is, the sores explained enough of what MPY32 was
2015-03-28T03:15:17 < karlp> it's not the "BSL" "rom" code you can get though i sit
2015-03-28T03:15:17 < dongs> Digital: Advanced Encryption Standard (AES256) Accelerator, CRC, DMA, HW MPY32
2015-03-28T03:15:38 < dongs> was wondering why mpy was bunchd in with crypto stuff

2015-03-28T03:20:10 < baird> zyp: a bad ISA for writing a compiler for, definitely. Geriatrics like me raised on 8-bit think it's the best thing since the 6809..
2015-03-28T03:20:29 < qyx_> that too

2015-03-28T14:57:38 < dongs> the stderiph examples cover polling/non-interrupt style i2c i believe

2015-03-28T15:30:37 < MrCircuitMatt> but I'm now writing the short over and over and that seems to be fine
2015-03-28T15:31:00 < dongs> https://github.com/multiwii/baseflight/blob/master/src/drv_i2c.c#L346 you might wanna do this adjusted to your stm32 version before trying any i2c comms
2015-03-28T15:31:23 < MrCircuitMatt> so it's either still something with reloading the DR and the corresponding shift register, or the stuff I'm loading is not what I should be loading
2015-03-28T15:31:44 < dongs> this will make sure any slave devices areng hogging the bus

2015-03-28T16:22:08 < Laurenceb_> chip scale core memory could be a thing?
2015-03-28T16:22:31 < Laurenceb_> i guess integrating the magnetic materials into the chip fab would be an issue
2015-03-28T16:25:17 < BrainDamage> the ferrites would have likely to be CVD'ed

2015-03-28T16:27:50 < BrainDamage> it sounds a bit of a pain tough,the sintered powder toroids have separate small grains structure, so they have low circiuation areas for the eddy currents at high freq
2015-03-28T16:28:20 < BrainDamage> i guess making the entire toroid tiny would compensate for being a single piece
2015-03-28T16:34:47 < Laurenceb_> yeah theres other stuff now
2015-03-28T16:35:01 < Laurenceb_> like ReRAM and Ferroelectrics and stuff

2015-03-28T20:19:22 < karlp> do they have any real reason to? or just "tradition"
2015-03-28T20:19:34 < karlp> because the rest of the industry is only building them 2.4gig solyutions :)
2015-03-28T20:20:15 < karlp> Laurenceb_: there's a few other transceivers in the atmel line, microchip hav ea new mrfxa, but it's not real common
2015-03-28T20:20:32 < upgrdman> iirc 800/900MHz can give better range
2015-03-28T20:20:33 < karlp> I've got some in a tube here I've never got around to doing anythign with, less bugs, more features than mrf24j
2015-03-28T20:20:53 < upgrdman> 2.4g is only nice because very small anennas and ~global unlicensed support
2015-03-28T20:21:03 < karlp> which is a very major niceity
2015-03-28T20:21:26 < upgrdman> sure, but wouldnt industry value performance over saving $2.
2015-03-28T20:22:03 < emeb> interesting... zyp's cyclesleep doesn't work on an F051
2015-03-28T20:22:11 < emeb> wonder if that feature is missing from the M0?
2015-03-28T20:24:44 < karlp> upgrdman: hard to say isn' tit? :)  if 2.4gig standard stuff is more reliable, but needs 15% more nodes per square meter, and cost 25% less, does it make a difference if 900meg reaches further?
2015-03-28T20:24:50 < karlp> (numbers all made up)
2015-03-28T20:24:57 < Laurenceb_> interesting, thanks for the info
2015-03-28T20:25:33 < upgrdman> k
2015-03-28T20:25:41 < Laurenceb_> well you can transmit 2W on 868
2015-03-28T20:25:50 < karlp> in some jurisdictions
2015-03-28T20:25:55 < Laurenceb_> and it propogates much better in industrial settings
2015-03-28T20:25:56 < Laurenceb_> sure
2015-03-28T20:26:13 < karlp> that "some jurisdictions" really is a major fucking pain in the arse, as I'm sure you're aware
2015-03-28T20:26:21 < Laurenceb_> yes
2015-03-28T20:26:24  * karlp shrugs
2015-03-28T20:26:28 < karlp> 433meg all the way right?
2015-03-28T20:26:32 < Laurenceb_> im looking at the numbers
2015-03-28T20:26:54 < Laurenceb_> 868 uses 1 to 2 orders of magnitude fewer nodes for my application
2015-03-28T20:26:57 < karlp> just make sure it's tiny packets and toss out security, because, "it's only critical industry control systems anyway right?"
2015-03-28T20:26:58 < Laurenceb_> than 2.4G
2015-03-28T20:27:04 < Laurenceb_> heh
2015-03-28T20:27:07 < karlp> heh, you actually modeled that yet?
2015-03-28T20:27:18 < Laurenceb_> yes, 434 is worse
2015-03-28T20:27:22 < Laurenceb_> which is suprising
2015-03-28T20:27:23 < karlp> I really doubt you'd get two orders of magnitude less in real life.
2015-03-28T20:27:34 < Laurenceb_> also 434 has more licensing issues
2015-03-28T20:27:45 < karlp> I'm not convinced you'd get one order of magnitude, but *shrugs*
2015-03-28T20:27:54 < Laurenceb_> well 3 times the range
2015-03-28T20:27:56 < Laurenceb_> so 3^2
2015-03-28T20:28:14 < Laurenceb_> much better in mining applications
2015-03-28T20:28:16 < karlp> I do know this, in our work, we're not getting, "900 is ok, 2.4 is out", we're getting, "wireless is FUCKN USELESS, plz use moah wirez"
2015-03-28T20:28:37 < Laurenceb_> it waveguides down the tunnels best at ~900
2015-03-28T20:28:39 < Laurenceb_> heh
2015-03-28T20:29:07 < karlp> surely that depneds on the shape of the tunnels of the particular mine?
2015-03-28T20:29:10 < Laurenceb_> sure
2015-03-28T20:29:17 < Laurenceb_> for the "average" mine
2015-03-28T20:29:21 < karlp> haha
2015-03-28T20:29:34 < Laurenceb_> 434 is good two
2015-03-28T20:29:46 < Laurenceb_> but 868 outperforms 868 in most mines
2015-03-28T20:29:53 < Laurenceb_> erm outperforms 434
2015-03-28T20:30:22 < Laurenceb_> 2.4G is completely useless in mines, line of sight only
2015-03-28T20:30:49 < Laurenceb_> the water mops it all up
2015-03-28T20:31:46  * Laurenceb_ is trying to create 868mhz "Zigbee + indoor positioning"
2015-03-28T20:32:04 < Laurenceb_> dunno if the ZigBee part is worth it, or if it should all be custom
2015-03-28T20:32:14 < karlp> depends who's paying the bill I guess :)
2015-03-28T20:32:48 < Laurenceb_> custom GPS style PRN beacons gives more lick budget
2015-03-28T20:32:50 < karlp> also, that corearray is fucking cool, neat to see that tiny
2015-03-28T20:32:53 < Laurenceb_> *link
2015-03-28T20:34:23 < _Sync_> Laurenceb_: what do you want to use for indoor pos?

2015-03-28T20:34:54 < emeb> Yeah - looks like the F0x0 parts don't implement the DWT cycle counter. :(
2015-03-28T20:35:05 < karlp> lame :(
2015-03-28T20:35:25 < _Sync_> no, what system not on where
2015-03-28T20:35:36 < _Sync_> I tried the decawave trash now, and it seems to work okay
2015-03-28T20:35:54 < Laurenceb_> _Sync_ a custom system
2015-03-28T20:36:00 < Laurenceb_> that im trying to design
2015-03-28T20:36:17 < _Sync_> sounds uneccessary 0o
2015-03-28T20:36:22 < Laurenceb_> as there doesnt seem to be anything on the market
2015-03-28T20:36:27 < Laurenceb_> decawave is UWB
2015-03-28T20:36:34 < _Sync_> but reminds me of my boss trying to to make something similar with BLE
2015-03-28T20:36:34 < Laurenceb_> big licensing issues
2015-03-28T20:36:40 < Laurenceb_> heh
2015-03-28T20:36:46 < _Sync_> is it?
2015-03-28T20:37:03 < Laurenceb_> well if you use the high bands UWB is fine
2015-03-28T20:37:12 < Laurenceb_> so for most applications thats no problem
2015-03-28T20:37:39 < Laurenceb_> industrial applications and mining, sub Ghz works with far fewer nodes
2015-03-28T20:37:52 < Laurenceb_> but sub Ghz UWB has licensing issues
2015-03-28T20:38:02 < _Sync_> yeah
2015-03-28T20:38:08 < Laurenceb_> ok if you only want to satisfy the FCC
2015-03-28T20:38:58 < Laurenceb_> so I'm thinking of something like this on 868/915
2015-03-28T20:39:00 < Laurenceb_> http://www.omnisense.co.uk/
2015-03-28T20:39:11 < Laurenceb_> modified Zigbee
2015-03-28T20:39:28 < _Sync_> I dunno, wouldn't it be easier to just throw down enough nodes with the decawave stuff instead of rolling your own
2015-03-28T20:39:40 < Laurenceb_> too many nodes
2015-03-28T20:39:42 < Laurenceb_> http://www.omnisense.co.uk/images/product-banner-1401.jpg
2015-03-28T20:39:47 < Laurenceb_> is dat some ubuntu
2015-03-28T20:40:07 < _Sync_> if you put down some every 20m that should work
2015-03-28T20:40:16 < _Sync_> but yeah that's a huge number in a mine
2015-03-28T20:40:26 < _Sync_> we also have to put a lot down in ships
2015-03-28T20:40:41 < Laurenceb_> every 20m  O_o
2015-03-28T20:40:50 < Laurenceb_> more like every 2km
2015-03-28T20:40:56 < Laurenceb_> or its too impractical
2015-03-28T20:40:59 < _Sync_> wat
2015-03-28T20:41:00 < _Sync_> 2km
2015-03-28T20:41:36 < Laurenceb_> ok maybe not that extreme, but it needs a lot of range
2015-03-28T20:42:02 < _Sync_> well, all the steel in ships forces us to I think 35m on average
2015-03-28T20:42:11 < _Sync_> but that's just some dumb troll research project
2015-03-28T20:42:16 < _Sync_> hence all the BLE shit
2015-03-28T20:42:22 < Laurenceb_> interesting
2015-03-28T20:42:25 < _Sync_> because dem sensormesh
2015-03-28T20:42:36 < _Sync_> but that's not going to work at all
2015-03-28T20:43:00 < Laurenceb_> im most interested in mining, there doesnt seem to be a practical location system there
2015-03-28T20:43:49 < _Sync_> same with ships, or at atleast nobody has really done stuff there

2015-03-28T21:16:14 < emeb> apparently I need to tweak the compiler options so that it doesn't use stuff that M0 can't handle. Thoughts?
2015-03-28T21:22:27 < kakeman> Basic Ethernet rate = 12.5 Mbps
2015-03-28T21:22:35 < kakeman> this sucks
2015-03-28T21:23:04 < scrts2> MBps or Mbps?
2015-03-28T21:23:14 < scrts2> because this is reasonable for MBps :)
2015-03-28T21:23:14 < kakeman> Mbps
2015-03-28T21:23:30 < PaulFertser> emeb: "-mthumb -march=armv6s-m" should be enough
2015-03-28T21:23:42 < kakeman> it would be just perfectly fine for  MBps
2015-03-28T21:24:04 < kakeman> user manual is saying maximum speed per direction is that
2015-03-28T21:24:14 < kakeman> for lpc1769
2015-03-28T21:25:31 < emeb> PaulFertser: hmmm... still doing the same thing
2015-03-28T21:26:23 < PaulFertser> emeb: frame 2; disassemble
2015-03-28T21:27:19 < PaulFertser> emeb: should show you exactly the instruction that caused it. Then you can try to figure what's wrong. Are you using gcc-arm-embedded btw? "arm-none-eabi-gcc -print-multi-lib" prints the options I cited here. If you're using something else, you might be getting wrong libgcc.

2015-03-28T21:33:36 < emeb> PaulFertser: thanks
2015-03-28T21:33:39 < PaulFertser> emeb: and what's the exact gcc command line when you build and link it?
2015-03-28T21:33:44 < emeb> figured it out
2015-03-28T21:33:47 < PaulFertser> emeb: what was it?
2015-03-28T21:34:05 < emeb> My Makefile was hosed - the final link stage didn't have the CPU flags set right.
2015-03-28T21:34:16 < PaulFertser> Aha
2015-03-28T21:34:59 < emeb> PaulFertser: I've got a lot of "cargo cult" in my Makefile
2015-03-28T21:35:08 < emeb> I really don't understand these things well enough...
2015-03-28T21:35:36 < PaulFertser> emeb: I like libopencm3's makefiles, they seem sane enough.
2015-03-28T21:36:27 < emeb> PaulFertser: thx - I'll take a look.
2015-03-28T21:39:07 < emeb> PaulFertser: what's the difference between -mcpu=cortex-m0  and -march=armv6s-m?
2015-03-28T21:39:12 < emeb> seems to do the same thing
2015-03-28T21:41:55 < kakeman> it seems maximum payload would be around 8Mbps
2015-03-28T21:42:20 < kakeman> 8-10
2015-03-28T21:45:09 < PaulFertser> emeb: I think no difference in this specific case, but probably makes sense for some other targets supported by GCC.
2015-03-28T21:47:12 < emeb> PaulFertser: thx!
2015-03-28T22:39:27 < kakeman> if I add section attribute do I need to exlude varibles from sections data or bss?
2015-03-28T22:40:11 < kakeman> or does added section override bss or data section of varible?

2015-03-29T11:23:15 < dongs> Selection of TI (Texas Instruments) as the main processor is dictated by several reasons. With almost equal energy consumption of both processors, energy consumption of TI allows computing of operations in sleep mode. Digit capacity and throughput of Cortex is higher, but Ritot watch has no need in additional computational capabilities. The organization of operation of peripheral devices at RISC is more optimal than ARM, including processing of some peripheral device
2015-03-29T11:23:27 < dongs> Choice of MSP430 processor is also caused by the economic reasons. Since we will use the periphery of TI,economically expedient to use processors from the same manufacturer.

2015-03-29T13:11:54 < PeterM> dongs, in a buck converter, thats the sync rectifier fet, so it sees the output current rather than the input current, and usually it is also on longer than the main switch

2015-03-29T14:59:00 < PeterM> karlp it's a standard halfbridge config, so you use them fr anything that needs a halfbridge
2015-03-29T15:00:38 < karlp> hrm, I haven't driven a motor since uni I don't think, with discrete BJTs, forgotten most of this stuff.
2015-03-29T15:01:17 < karlp> so that richtek driver part, with three phases, shows it wired to three half-bridges?
2015-03-29T15:01:42 < karlp> how's that work? I thought full bridge was two halfs, not 3 halfs?
2015-03-29T15:02:09 < PeterM> three phase motors
2015-03-29T15:02:15 < karlp> ahh, they expect you to use it as three halfs for fans and shit too, not for motors.
2015-03-29T15:02:24 < PeterM> yeah
2015-03-29T15:02:34 < PeterM> or dc dc converters (sync buck sync boost etc
2015-03-29T15:02:49 < PeterM> well 3phase motors too
2015-03-29T15:03:37 < PeterM> that richtek part is designed for dc-dc converters but it conveniently works for brushless dc motors too
2015-03-29T15:04:24 < karlp> just using two of the channels though?
2015-03-29T15:04:50 < PeterM> no, brushless dc motors are just 3phase motors but with higher inductance to bne driuven wiht squarewaves

2015-03-29T15:06:20 < dongs> yes brushed stuff
2015-03-29T15:06:46 < PeterM> the magnetic fields are mechanically commutated instead of being electrically commutated

2015-03-29T20:03:34 < kakeman> could you limit flying height of balloon by having a very thin long wire hanging from it?
2015-03-29T20:03:59 < kakeman> that would be all way to ground

2015-03-29T20:06:11 < kakeman> when lift and weight become equal
2015-03-29T20:07:31 < kakeman> acceleration = 0
2015-03-29T20:07:44 < BrainDamage> it wouldn't be very stable
2015-03-29T20:08:14 < BrainDamage> balloon leaks
2015-03-29T20:08:35 < BrainDamage> also it gets heated from sun, so expands / contract during the day

2015-03-30T03:53:10 < dongs> waht does a nigga do with powdered milk
2015-03-30T03:53:28 < karlp> some old australian christmas food recipes, rum balls for instance,
2015-03-30T03:53:38 < karlp> also making your own backpacking meals
2015-03-30T03:56:18 < dongs> Combining the technology associated with .glamping. and the outdoorsy craftsmanship it takes to build a campfire, the BioLite BaseCamp is a completely off-the-grid cooking and energy solution powered by wood that you can cook your meals on. Yes, you.ll still need to collect fallen branches and firewood, giving you that .Survivorman. feeling that pairs nicely with camping -- but smaller and easily manageable pieces will suffice to make this fire burn.

2015-03-30T21:45:34 < superbia> and get a cheap road bike for city.. one that you wont have to worry some1 will steal

2015-03-30T21:49:15 < superbia> that franken-bike
2015-03-30T21:49:51 < kakeman> there is no excuse not to have hydraulic brakes
2015-03-30T21:50:01 < superbia> except the price
2015-03-30T21:50:14 < kakeman> cheapest shimano 20eur
2015-03-30T21:50:21 < kakeman> +discs
2015-03-30T21:50:25 < superbia> and the fact you need 200eur to get good hydros, where vbrakes outperform everything cheaper
2015-03-30T21:50:58 < kakeman> I put 200eur to my hydros
2015-03-30T21:51:08 < superbia> what model
2015-03-30T21:51:13 < superbia> i cant tell from the pic
2015-03-30T21:51:17 < superbia> i see its a shimano
2015-03-30T21:51:26 < superbia> but not know the model
2015-03-30T21:51:49 < kakeman> http://www.chainreactioncycles.com/fi/en/shimano-xt-m785-disc-brake/rp-prod67208 this looks like it

2015-03-30T21:52:26 < superbia> the lever has those plastic shina part right?
2015-03-30T21:52:37 < superbia> or does yours have metal plastic shining part
2015-03-30T21:52:49 < kakeman> metal shining plastic crap
2015-03-30T21:52:56 < superbia> its plastic or metal
2015-03-30T21:52:57 < kakeman> actually glassfiber
2015-03-30T21:53:05 < superbia> its plastic that emulates metal?
2015-03-30T21:53:16 < superbia> but you can feel its plastic
2015-03-30T21:53:18 < kakeman> I scrached it and it looks like composite inside
2015-03-30T21:53:25 < kakeman> can not feel it
2015-03-30T21:53:25 < superbia> y friend had bought those
2015-03-30T21:53:30 < superbia> 200eur indeed
2015-03-30T21:54:04 < superbia> good brakes indeed, but would preffer something like a SAINT, or even some XX, or any stronger avid brakes
2015-03-30T21:54:23 < superbia> similar price, or maybe 250eur, and i have tried avid's and they are monsters
2015-03-30T21:54:34 < superbia> ofc. i tried on xc/freeride
2015-03-30T21:55:13 < kakeman> by braking power you can't clearly beat these without adding some serious money to equation
2015-03-30T21:55:20 < superbia> you can
2015-03-30T21:55:32 < superbia> i wrote SAINT groupset brakes
2015-03-30T21:55:37 < superbia> or avid's
2015-03-30T21:55:48 < superbia> saint is like a downhill groupset shimano makes
2015-03-30T21:56:05 < kakeman> I have 203mm rotor at front
2015-03-30T21:56:39 < superbia> on that frame its a joke :)

2015-03-30T21:58:40 < superbia> i can get like 200eur for mine.. and i collected the items to put it together.
2015-03-30T21:59:08 < superbia> dont think i can get anything for that money.. and V-brakes dont draw much attention :)
2015-03-30T21:59:44 < kakeman> you know what frame I have there?

2015-03-30T22:01:12 < superbia> also SPD is more "gay" round here

2015-03-30T22:05:32 < superbia> preiss :)
2015-03-30T22:05:49 < superbia> and its used for extreme shit like freeride/xc
2015-03-30T22:05:58 < superbia> for city you can use 4x cheaper tire..
2015-03-30T22:06:29 < kakeman> those 50mm I have cost under 20eur per one
2015-03-30T22:06:54 < superbia> if you haave buy the arduinos
2015-03-30T22:07:56 < superbia> on mine i have ritchy tires, paid 8eur per tire.. still have 80% meat on them after 1 season
2015-03-30T22:08:07 < superbia> its something ment to be replaced

2015-03-30T22:11:08 < superbia> kakeman: also you would be surprised if you try something off-roadish, how much impact can tire have on the ride
2015-03-30T22:11:37 < superbia> from handling, agility, stability, cornering speed etc..
2015-03-30T22:12:12 < superbia> not saying everything schwalbe makes is "Perfect"... and you could find some cheaper tires suit your driving better
2015-03-30T22:13:00 < kakeman> I offroad using these I just lower preasure to 2bar
2015-03-30T22:13:11 < kakeman> trails on hillside and stuff
2015-03-30T22:13:44 < superbia> not everything schwalbe makes is the best
2015-03-30T22:14:03 < kakeman> I got these purely by how these look
2015-03-30T22:14:29 < superbia> that is the best way how to do LIFE
2015-03-30T22:15:00 < superbia> what is the average speed you are driving
2015-03-30T22:15:07 < superbia> and maximum speed you had driven
2015-03-30T22:15:42 < Steffanx> dutchland is too flat, so the only "fun" here is a SPD bike.
2015-03-30T22:15:58 < Steffanx> racing* whatever you call it

2015-03-30T22:16:28 < Steffanx> down hill kakeman :P
2015-03-30T22:16:41 < kakeman> I think my average is around 23-25
2015-03-30T22:16:47 < superbia> km/h
2015-03-30T22:16:49 < kakeman> yes
2015-03-30T22:16:59 < superbia> some maximums?
2015-03-30T22:17:23 < kakeman> how long duration?
2015-03-30T22:17:32 < superbia> minute

2015-03-30T22:18:20 < superbia> are you in a bike club or just hobbying
2015-03-30T22:18:27 < kakeman> just times to place A to B
2015-03-30T22:18:33 < Steffanx> you don't record you're trips using gps?

2015-03-30T22:19:03 < PaulFertser> I have a cheap MTB and an entry-level road racing bicycle. The feeling is considerably different.
2015-03-30T22:19:12 < superbia> he cant text and drive
2015-03-30T22:19:22 < kakeman> I have entry level road cycle too
2015-03-30T22:19:46 < kakeman> I use it when I don't want to sweat to form on my skin
2015-03-30T22:20:24 < kakeman> or I'm in hurry
2015-03-30T22:20:36 < PaulFertser> I got RST F1RST fork off ebay, it seems to be a rather nice fit for a crappy MTB.
2015-03-30T22:20:53 < superbia> crappy fork for crappy mtb
2015-03-30T22:21:17 < superbia> there was a slovakian company that made kickass mtb-s like 2 years ago
2015-03-30T22:21:52 < superbia> i am sorry i didnt get their mtb..
2015-03-30T22:22:18 < superbia> today same mtb costs 1kilo eur, and they sold it for 400eur.
2015-03-30T22:22:21 < Steffanx> ask ranewen if he can help you get one
2015-03-30T22:22:32 < PaulFertser> This F1RST can be adjusted by varying air pressure in one of its legs. And I really need that because all the spring coils forks I've tried were too sturdy for my weight.

2015-03-30T22:41:01 < kakeman> next thing is a mask with heat exchanger so I can go -35

2015-03-30T23:48:11 < kakeman> after that ok

2015-03-31T00:00:07 < baird> The bicycle tire leak-sealer I've used gets very nasty in extreme heat (i.e: Australia). Can't use it on tires that've already been patched, because it'll dissolve the glue..
2015-03-31T00:02:18 < kakeman> different things leak-sealer and tubeless sealant
2015-03-31T00:05:03 < kakeman> with tubeless tyre and tubeless wheel you can ride even without sealant if you don't puncture tyre

2015-03-31T01:21:03 < malinus> I just realized that the atmega328p costs ~2.5x more than the (cheaper ones) stm32f0.
2015-03-31T01:21:28 < malinus> atmega328p would be ~3E, the stm32f0 is around 1.5E

2015-03-31T01:46:11 < ds2> was the paperwork from a guy with horns and a redcape?
2015-03-31T01:46:17 < malinus> and a pencil is probably 100x cheaper
2015-03-31T01:48:28 < malinus> At least he doesn't imply (the chinese guy), that it's useful.
2015-03-31T01:50:24 < dongs> Two former U.S. government agents face charges related to stealing hundreds of thousands of dollars worth of bitcoin while assisting with an investigation of the Silk Road underground online marketplace, with one accused of using a fake online persona to extort money from operators of the site. Facing charges of wire fraud and money laundering are Carl Force, 46, of Baltimore, a former special agent with the U.S. Drug Enforcement Agency, and Shaun Bridges, 32, of Lau
2015-03-31T01:50:32 < dongs> lol the irony
2015-03-31T01:51:44 < _Sync_> yeah
2015-03-31T02:04:54 < malinus> Hmm element14(farnell), seems to be much cheaper than mouser. It looks like they only exepect to ship to companys though (they require a company number and name etc.).
2015-03-31T02:11:41 < baird> Not here in Australia, at least. Certainly eased up when they became a Raspberry Pi supplier.
2015-03-31T02:12:35 < baird> I had to get a Visa card, though.
2015-03-31T02:15:19 < malinus> It's not like they will check it anyway -_o_-

2015-03-31T02:52:14 < qyx_> huh, i have no company name and "company number" (whats that?)
2015-03-31T02:54:43 < malinus> Well I have to fill those in, after pressing "order". A "comapny number" is called different things all around: http://en.wikipedia.org/wiki/Central_Business_Register_%28Denmark%29

2015-03-31T03:06:07 < zyp> I can say for a fact that farnell does only send to business customers in norway
2015-03-31T03:07:22 < zyp> or didn't, I've not even tried ordering from them for a while
2015-03-31T03:07:30 < zyp> did*
2015-03-31T03:08:38 < malinus> zyp: sounds like the same thing then. I wonder what they do if I just ship to my private address, providing a fake company name.

2015-03-31T03:12:46 < malinus> would they really bother with that?
2015-03-31T03:13:05 < zyp> would they bother asking if they didn't need it?
2015-03-31T03:13:22 < dongs> they're making sure youre not building bombs
2015-03-31T03:13:25 < zyp> might be for tax purposes
2015-03-31T03:13:25 < malinus> maybe it's just some law-thing.
2015-03-31T03:13:50 < malinus> exactly. But you have to pay full tax anyway (and can get it returned later, instead).

2015-03-31T03:19:08 < zyp> like having to do a more complex tax return, and you have other rights with regards to unemployment benefits and so on
2015-03-31T03:19:11 < dongs> you can start a japcorp with 1 yen
2015-03-31T03:19:21 < dongs> but it takes ~$2500 for paperwork

2015-03-31T06:06:20 < PeterM> i get the feeling the luggage in this picture was not the intended subject http://en.wikipedia.org/wiki/File:Girls_in_Harajuku_---_Kawaii%3F.jpg
2015-03-31T06:06:34 < dongs> haha
2015-03-31T06:06:58 < PeterM> i mean, if it was the framing on the luggage would be half decent

2015-03-31T06:15:56 < emeb> yay - F030F4 blinking
2015-03-31T06:17:59 < PeterM> aww yeee' now you start innovating

2015-03-31T06:18:45 < emeb> next project: get it talking -> https://github.com/emeb/f051_discovery_talk
2015-03-31T06:18:57 < emeb> just need to re-arrange some IO

2015-03-31T06:42:42 < emeb> could probably run it at 16MHz if the PWM didn't need 1k period to get the full resolution
2015-03-31T06:43:18 < emeb> so if you had an MCU with on-chip DAC or SPI DAC then you could run it slower.
2015-03-31T06:43:55 < dongs> nwat
2015-03-31T06:43:56 < dongs> er
2015-03-31T06:43:57 < dongs> neat
2015-03-31T06:44:26 < emeb> OK - got it working on the 030F4. Cheep speech
2015-03-31T06:44:53 < upgrdman> any video clips of it talking?

2015-03-31T06:46:03 < upgrdman> lol nice
2015-03-31T06:46:33 < emeb> that all fits in ~8kB
2015-03-31T06:47:23 < upgrdman> guessing it takes syllables and maps them to a sequence of PWM values?
2015-03-31T06:48:04 < emeb> this one actually uses complete words and splits them into 20ms frames of encoded data
2015-03-31T06:48:23 < emeb> each frame has pitch, energy and filter coefficients to model the vocal tract.
2015-03-31T06:49:48 < emeb> so a word looks like this: https://github.com/emeb/f051_discovery_talk/blob/master/main.c#L54
2015-03-31T06:50:35 < upgrdman> cool
2015-03-31T06:52:52 < dongs> emeb: wahts with little pops sometimes
2015-03-31T06:53:56 < emeb> in the instagram?
2015-03-31T06:54:06 < dongs> y
2015-03-31T06:54:19 < emeb> dunno - could be something with the way he ganked my code.
2015-03-31T06:54:41 < emeb> LPC stuff is kinda funky though - it has some discontinuities. Goes with the territory
2015-03-31T06:57:12 < emeb> oh - another thing it could be: I did dig into the lattice filter a bit and saw that it had some truncation errors building up.
2015-03-31T06:57:33 < emeb> end result is slight DC offset in the output that may translate into pops when words start/stop.
2015-03-31T06:57:43 < emeb> should be easy to fix with some rounding.

2015-03-31T11:35:29 < PeterM> i assume you hve a round pcb that will sit in the bottom of a cylinder which you wish to thermally attachg to the bottom with a thermal pad or something? if this is the caser, make a few long thin tracks tht run around the pcb edge so they act as a resistor, tehn PWM it for desired power dissipation
2015-03-31T11:37:16 < trepidaciousMBR> You can get flexible PCB heaters, with adhesive to bond them to whatever you are heating.
2015-03-31T11:38:35 < PeterM> thats an idea. and if they're too expensive, just get some shitty LED tape and put resistors in place of the LEDs
2015-03-31T11:46:58 < dongs> he's reinventing 3d dicker heatbed

2015-03-31T14:20:40 < ReadError> you can snap it off and use it for other shit if you want
2015-03-31T14:22:12 < malinus> All the f0 should be almost 100% compatible, right? In which case I might as well just get the nucleo. The idea was that I wanted to make a custom board, because there was no devboards with that particular chip (which I'm panning to use in a specific application).
2015-03-31T14:23:40 < dongs> theres the F100
2015-03-31T14:23:42 < dongs> which is old
2015-03-31T14:23:45 < dongs> and F0xx
2015-03-31T14:23:49 < dongs> which is cortex m+
2015-03-31T14:23:52 < dongs> er m0+
2015-03-31T14:23:54 < dongs> f100 is m0
2015-03-31T14:24:01 < dongs> which one were you going to use?
2015-03-31T14:24:18 < zyp> isn't all f0 m0?
2015-03-31T14:24:23 < dongs> no?
2015-03-31T14:24:24 < zyp> while l0 is m0+?
2015-03-31T14:24:28 < dongs> i thought the new shit is 0+
2015-03-31T14:24:30 < malinus> m0 (f0xx)
2015-03-31T14:24:41 < zyp> l0 is the new shit
2015-03-31T14:24:46 < dongs> oh hm
2015-03-31T14:24:50 < dongs> ohhh right yeah
2015-03-31T14:25:04 < dongs> the l0 as opposed to l15x stuff
2015-03-31T14:25:12 < malinus> STM32F030x8 to be specific
2015-03-31T14:25:25 < dongs> i thought the new f0x0 shit was also m+ but i guess thier salespoint is just being cheapshit
2015-03-31T14:25:48 < dongs> maybe we should all switch to MSP432
2015-03-31T14:25:51 < dongs> for max pro
2015-03-31T14:25:52 < malinus> yep, like 1.5E each
2015-03-31T14:25:57 < karlp> dongs f100 is not f0, it's f1 value line
2015-03-31T14:26:08 < dongs> but its m0, isnt it?
2015-03-31T14:26:15 < dongs> or did i fuck that up too
2015-03-31T14:26:23 < jpa-> F1 is M3
2015-03-31T14:26:26 < dongs> meh, its m3. k
2015-03-31T14:26:30 < malinus> msp? I thought they gave up
2015-03-31T14:26:34 < malinus> :P
2015-03-31T14:26:34 < dongs> disregard everythign i said, i suck cocks
2015-03-31T14:26:57 < dongs> malinus: they renamed tiva line again and now its msp432 with cortex m4
2015-03-31T14:27:09 < malinus> oh
2015-03-31T14:27:21 < zyp> so dumb
2015-03-31T14:27:22 < malinus> Is there a free toolchain for that?
2015-03-31T14:27:23 < jpa-> because it's so freaking logical to have a totally different CPU under almost the same product name
2015-03-31T14:27:29 < dongs> stellaris -> tiva -> msp432. the story of TI failing it
2015-03-31T14:27:42 < jpa-> malinus: free toolchain for ARM? yes, it's the same cortex m4 as anything else
2015-03-31T14:27:55 < malinus> I wrote that before reading it was the m4
2015-03-31T14:28:19 < dongs> thre's some ROM wiht like ~32k? worth of some propriteary TI library on it tho
2015-03-31T14:28:21 < dongs> with driversr + shit
2015-03-31T14:28:39 < dongs> maybe it has a built in arduino interpreter
2015-03-31T14:28:44 < malinus> lol'd
2015-03-31T14:29:16 < malinus> when I can have mongoDB?
2015-03-31T14:29:37 < jpa-> what is stopping you?
2015-03-31T14:30:23 < malinus> no node.js based compiler
2015-03-31T14:30:43 < jpa-> you can compile clang to javascript

2015-03-31T15:21:20 < dongs> ohh
2015-03-31T15:21:22 < dongs> a new zano update
2015-03-31T15:21:47 < dongs> We have completed our motor tests and had two stand out winners with efficiency well above all the others. The most efficient would have been my preference but it did lack the extra lift required to comfortably support the extended battery so the next choice was the next most efficient motor (95% as efficient as the best motor) but has substantially more lift.
2015-03-31T15:21:52 < dongs> haha
2015-03-31T15:22:02 < dongs> I am currently working on the tuning of Zano for this motor. Every change results in a butterfly effect. So changing the motors, changes magnetic fields on Zano which need to be adjusted for. Different motors have different output per watt of input. This requires retuning of the PID control systems. All routine but need to be done and done carefully.
2015-03-31T15:22:07 < dongs> w u t
2015-03-31T15:22:27 < dongs> To find the best mix of power efficiency for the digital electronics and performance, the digital supply rail voltage has been adjusted. This change requires a voltage sensing array update to better accommodate the battery voltage sensing. Once again, only a single change to short lead time parts on the bill of materials.
2015-03-31T15:22:33 < dongs> haha
2015-03-31T15:22:34 < dongs> this guy is just spreading bullshit nonstop
2015-03-31T15:23:00 < dongs> One thing has arisen that may slow us down. All consumer products require compliance certification for the regions they will be sold in.

I know not as much footage as people would like to see but it is there including some footage of Zano flying without any plastic parts. The next video footage of Zano flying that we will publish will be of the latest version as we enable each part of the autonomy and document it. It is coming but as I have mentioned, our priorities had to shift and focus on the project deliverables (ordering, bill of mat
2015-03-31T15:24:15 < dongs> For me, I am working right now with the new motors and tuning Zano. Got a few funny vibration issues that I need to resolve but all part of the process.

2015-03-31T16:16:06 < Getty> it will be massivly limited if they ever release it, it will for sure not be able to follow your bike ride through the wood
2015-03-31T16:16:08 < Lux> you could build something like zano, that works
2015-03-31T16:16:19 < Getty> yeah bigger and with higher price
2015-03-31T16:16:22 < Lux> but it won't do image processing etc

2015-03-31T16:31:36 < karlp> jpa-: is it still gpl incompatible?
2015-03-31T16:31:50 < karlp> it was in the past, but they cleared up lots of the licensecing dind't they?

2015-03-31T20:12:48 < qyx_> Laurenceb: xeno XL-205F is 19Ah and weights 97g
2015-03-31T20:12:57 < qyx_> it looks a bit better
2015-03-31T20:14:19 < Laurenceb> nice, thanks
2015-03-31T20:14:37  * Laurenceb is looking for power sources for a wireless sensor node
2015-03-31T20:14:50 < qyx_> me too
2015-03-31T20:15:00 < Laurenceb> ive seen some 38Ah DD cells
2015-03-31T20:15:05 < qyx_> but my "low power" wireless node needs ~15mA continuously
2015-03-31T20:15:10 < Laurenceb> eek
2015-03-31T20:15:13 < Laurenceb> zigbee?
2015-03-31T20:15:21 < qyx_> no, 433MHz
2015-03-31T20:15:27 < Laurenceb> ah
2015-03-31T20:15:28 < qyx_> with just CSMA MAC
2015-03-31T20:15:32 < Laurenceb> ok
2015-03-31T20:15:39 < qyx_> i should innovate something more practical
2015-03-31T20:15:40 < Laurenceb> SPIRIT1 looks quite nice
2015-03-31T20:16:01 < qyx_> yep, i have an unpopulated borad for it
2015-03-31T20:16:05 < Laurenceb> but si446x with preamble detect/sleep mode is ~3.5mA, so a lot better
2015-03-31T20:16:27 < qyx_> huh, can it listen while sleeping?ň
2015-03-31T20:18:58 < Laurenceb> yes
2015-03-31T20:19:29 < Laurenceb> it you have a double length preamble, then it wakes up and looks for bit edges
2015-03-31T20:19:48 < Laurenceb> for ~1.5 bit periods every few bytes
2015-03-31T20:20:25 < Laurenceb> you could try synchronising the network too
2015-03-31T20:20:40 < Laurenceb> so everything sleeps for ~10 seconds the wakes up for ~1 second
2015-03-31T20:20:44 < Laurenceb> *then
2015-03-31T20:21:14 < qyx_> yep, i am about to try this timeslot approach
2015-03-31T20:21:22 < qyx_> but with much shorter slots
2015-03-31T20:21:32 < qyx_> and some distributed timeslot allocation algo
