[00:01] <fsphil> all I can think of is that it's being optomised-out by the compiler
[00:01] Dan-K2VOL (~Adium@96-28-238-68.dhcp.insightbb.com) left irc: Ping timeout: 272 seconds
[00:06] <Zuph> I'm looking at the disassembly and it's all there..
[00:07] <fsphil> the call to the function in outputParse.c too?
[00:08] <Zuph> yes
[00:08] <fsphil> something in the function returning early?
[00:10] <fsphil> or the function in outputParse.c that calls the i2c stuff itself not being called or returning early before the call?
[00:11] <Zuph> Not that I can see.
[00:11] <fsphil> does something before or after the call get executed?
[00:12] <Zuph> Yes, and it does those things just fine.
[00:15] <fsphil> are you able to run it through a debugger at all?
[00:16] <Zuph> Yes, but my GDB skills are miserable.
[00:17] <fsphil> hehe, same here
[00:18] <fsphil> should be simple enough to set a breakpoint just before the function should get called
[00:18] <fsphil> break filename:line
[00:18] <fsphil> something like that
[00:18] <SpeedEvil> Turned off optimisation completely/
[00:19] <SpeedEvil> -Ofuckno
[00:19] <Zuph> Except I'm looking at the disassembly of the file I'm putting on the chip, and the function calls are there.
[00:20] <SpeedEvil> qh
[00:20] Last message repeated 1 time(s).
[00:20] <fsphil> how are you linking the objects?
[00:21] <SpeedEvil> hot-melt?
[00:21] <Zuph> Here's the exact line: avr-gcc -o bin/Debug/WSBFlightComputer.elf obj/Debug/lib/bmp085.o obj/Debug/lib/ds3231.o obj/Debug/lib/i2c.o obj/Debug/lib/tmp100.o obj/Debug/logging/openlog.o obj/Debug/main.o obj/Debug/parsing/epoch.o obj/Debug/parsing/gps.o obj/Debug/queue.o obj/Debug/comm/outputParse.o -mmcu=atmega324p -Wl,-Map=bin/Debug/WSBFlightComputer.elf.map,--cref -Wl,-u,vfprintf -lprintf_flt -Wl,-u,vfscanf -lscanf_flt -lm
[00:24] <fsphil> long shot, but try swapping the position of outputParse.o and main.o
[00:25] <Zuph> Tried it, no change.
[00:27] <fsphil> adding -Wall output any warnings?
[00:30] <Zuph> Just some minor pointer type mismatches in an unrelated part of the file.
[00:31] <SpeedEvil> Some processors skip addresses that end in 13, as they're superstitious.
[00:31] <NigeyS> lol
[00:32] <fsphil> Did you try putting a breakpoint on the calling line?
[00:33] <fsphil> Scary thing about Friday the 13th, is it's *always* followed by a Monday the 16th! Spooky.

[01:21] <Dan-K2VOL> that's lame
[01:22] <NigeyS> yup, im hoping its just a dodgy antenna, can get a new 1 for 8quid as opposed to a ublox module which is £40 :/

[14:21] <rjharrison_> Typical !
[14:21] <rjharrison_> But I have a bit more home that they will go with it now
[14:21] <Upu> I have someone near there who said we can launch from their land so applying for a NOTAM for there
[14:21] <Upu> as well
[14:21] <Upu> Can I pop over to see you some time
[14:22] <rjharrison_> Sure
[14:22] <Upu> sweet
[14:22] <rjharrison_> Do you have a date in mind?
[14:22] <Upu> Well weather is killing me atm
[14:22] <rjharrison_> Come and play with the toys and bring the pink box allong
[14:22] <Upu> a few weekends time, I was going to do a long distance test today but we are snowed in
[14:23] <Upu> annoying Audi have my car and I have this automatic 2 wd thing which sucks in the snow
[14:23] <rjharrison_> Yep my BMW is also crap in the snow
[14:23] <Upu> I'll come back to you on that
[14:23] <rjharrison_> Sure np
[14:23] <rjharrison_> Do you have my number
[14:24] <Upu> but appreciated, I'm good to launch tbh
[14:24] <Upu> no PM me it if you don't mine
[14:24] <Upu> mind
[14:24] <Upu> just have some questions about tracking it etc
[14:25] <rjharrison_> TBH it's pretty easy assuming it's txing the correct info
[14:25] <rjharrison_> You're not likely to loose it
[14:25] <rjharrison_> the signals are easy to pick up. you'll feel happier after you have done some long distance testing
[14:26] <Upu> yeah well my parents house has LoS to the moors 5 miles away
[14:26] <Upu> so I was going to hang it in their back bed room and take the dog up to the moors :)
[14:26] <rjharrison_> Yep sounds good if you can get 5 on the ground thats worth 100 in the air
[14:26] <Upu> If I can get it over 5 miles I should be good
[14:27] <rjharrison_> Yep have you got a gt 817?
[14:27] <Upu> then just the filler I need to work on these Hwyoee balloons have a very large filler
[14:27] <Upu> FT817 yeah
[14:28] <Upu> I've picked up telemetry from a number of launches but never been 100% happy with it
[14:30] Nick change: shenki_ -> shenki
[14:31] <rjharrison_> If I get 5 we could do a test from here
[14:31] <rjharrison_> im hd8 0wq
[14:32] <Upu> suspect you might be over the edge of the hill
[14:32] <Upu> hx3 7ny
[14:32] <Upu> possibly if drove up to my normal recieving spot
[14:33] <Upu> however thats not happening at the moment
[14:33] <rjharrison_> cool
[14:33] <Upu> you have a fixed antenna on the house ?
[14:33] <rjharrison_> I'm very near Emily moor mast
[14:33] <Upu> yeah I go up there alot
[14:33] <rjharrison_> Yep tri bander
[14:33] <rjharrison_> I'm about 3 min drive from the mast
[14:33] <Upu> I could go plug it in and try it
[14:34] <Upu> I go to Skelmanthorpe all the time
[14:34] <rjharrison_> I'v goto to take the kids out but perhaps tomorrow or this evening
[14:34] <Upu> sure
[14:34] <Upu> be interesting to see if you get get it
[14:35] <rjharrison_> Yep it's a lot easier than been out on the moore :)

[15:06] <jgrahamc> Afternoon
[15:06] <jgrahamc> Very exciting moment just now. First time my flight computer has transmitted RTTY which has been received on my radio and decoded by fldigi.
[15:06] SpikeUK (~chatzilla@pdpc/supporter/monthlybyte/spikeuk) joined #highaltitude.
[15:07] <jgrahamc> Not surprised it worked since I'd been pretty careful about testing, but seeing the string come out and hearing the RTTY was awesome.
[15:07] <NigeyS> aha! pretty neat when it starts working isn't it :D
[15:07] <NigeyS> i saw you had you parachute delivered to
[15:07] <jgrahamc> Only issue is the shift is too tight. It's about 300Hz so I need to mess with resistor values to get it to 425Hz
[15:08] <NigeyS> yeah the shift can take a bit of fiddling, i normally get 600ish then have to fiddle a bit to get down to 425 / 350
[15:09] <jgrahamc> Yes, I did also get the parachute. Looks good. I'm very close to competion now. Need to take some stuff off breadboards and do some soldering, but that's about it.
[15:09] <NigeyS> excellent, looks like you can make a march launch ?
[15:10] <rjharrison_> Laurenceb where are you ? you know the local wel
[15:10] <rjharrison_> l
[15:10] <jgrahamc> I'm hoping for a sunny, calm weekend in March. Next weekend I'm going up to my parents place and am planning to do a distance test of the transmitter with them. After that I think I'll be happy with everything.
[15:11] <NigeyS> hey robbie, didnt see you there :o
[15:11] <jgrahamc> Anyone else got an FT-790R?
[15:11] <NigeyS> i have
[15:11] <rjharrison_> yep
[15:11] <rjharrison_> off to ball park
[15:11] <jgrahamc> So, I bought one on eBay that's in immaculate condition but I need to replace the batteries because they are ancient. Has anyone tried replacing with NiMH?
[15:12] <NigeyS> let me check, cant remember what 1's i used in mine tbh
[15:14] <NigeyS> standard alkaline in mine, they seem to last a long time to
[15:15] <jgrahamc> OK. So you just stuck 9 C cells in and didn't worry about recharging. I guess I could just do that.
[15:15] <jgrahamc> Not a bad idea.
[15:17] <NigeyS> yups, theyre not expensive ones either, maplins own brand, have been in there for 5 months, no problems or power drain as of yet, i think if you use rechargeables they mention a dummie battery or something ?
[15:17] <rjharrison_> You can try MiMH it won't cause a problem. It might not work due to the slightly lower V
[15:17] <rjharrison_> On RX they should last a while
[15:17] <NigeyS> Robbie do you have a launch in March to?
[15:18] <jgrahamc> I think I'll just stick some C cells in there and forget about recharging.

[16:00] <MrCraig> was my post too long? I got booted
[16:03] <MrCraig> Anyway, I need voltage supply advice again. My processor requirements aren't as low as I'd hoped in practice. I can supply 4.5v (3xAAA) to drive the PIC and ntx2 (regulated internally 2.8) and regulate that myself to 3.3v for the lasseniQ - or I can supply 9v and regulate twice, once down to 5v for the pic and then again to 3.3v
[16:04] <MrCraig> I think 9v down to 5v is a large drop off and a lot of waste, but I fear the 4.5v option dropping too low during the flight.
[16:07] <Darkside> why are you using 9v?
[16:07] <Darkside> use a few AA lithiums
[16:07] ejcweb (~chatzilla@constantine.chu.cam.ac.uk) joined #highaltitude.
[16:08] <Darkside> they work at ridiculously low temperatures, have a high current capacity, and are light
[16:08] <Darkside> put in 4 of them, there's 6v, which you can probably wotk with
[16:08] <Darkside> work*
[16:09] <MrCraig> ok - you think 3xAA = 4.5v is too low then?
[16:09] <Darkside> for a 5v microcontroller, yes
[16:09] <Darkside> :P
[16:10] <Darkside> use more batteries, and if you're worried about regulaor cutoff, use a LDO regulator
[16:10] <Darkside> if you're worried about 'wasting' power, then use a switchmode regulator
[16:10] <MrCraig> yeah - I've not been getting results from the controller at much less, but the datasheet boasts a wide operating voltage range 2.0v - 5.0v :-/ had hoped to get away with less juice
[16:11] <MrCraig> Oh the waste it's self is not the biggest concern - it just felt like if I was wasting so much I was probably going about it the wrong way
[16:11] <ejcweb> Just wondering if anyone has ever used MMSSTV to decode SSTV images? I've got a test WAV file that I've generated that I want to test, but can't figure out how to load it...
[16:11] <MrCraig> ok - I'll go with 4xAA liths and build the flight computer to operate off of 6v, regulating as required.
[16:12] <Darkside> ejcweb: can that program decode wave files?
[16:12] <MrCraig> ty Darkside
[16:13] <ejcweb> Darkside: Perhaps not, I assumed it might be able to. It's got a menu option allowing you to load sound files, but only of a custom *.mmv format.
[16:13] <Darkside> ejcweb: thats pretty sucky then
[16:13] <Darkside> just use a loopback audio thingo
[16:13] <ejcweb> I've seen talk on some forums of people decoding wav files, though perhaps they were playing it through there soundcards.
[16:13] <Darkside> yeah
[16:14] <Darkside> or for more fun, play it via a radio link P
[16:14] <Darkside> :P
[16:14] <Darkside> then it's a bit more realistic
[16:15] <Darkside> anyway, its 2:45AM where I am

[19:00] <fsphil> quick question for those who've done their intermediate radio exams: the book seems to be suggesting the VFO be soldered with the pcb as gnd, and all the parts directly soldered together, and suspended above (not touching) the board. is that right?
[19:00] <fsphil> (not touching except for when it's a gnd)
[19:02] <SpeedEvil> that is one construction techniques - it's called dead-bug
[19:02] <fsphil> ah, I thought dead-bug skipped the pcb entirely
[19:02] <SpeedEvil> The advantageis it has a constant ground plane
[19:03] <SpeedEvil> Well - some can
[19:03] <SpeedEvil> The disadvantage is it can be not so robust
[19:03] <SpeedEvil> Microphonics are bad.
[19:04] <fsphil> I might just use some stripboard to be honest

[20:59] <mattltm> Lol - good call :)
[20:59] <MrCraig> not the greatest of distractions, but a distraction all the same :)
[21:00] <MrCraig> how 'bout you, anything new?
[21:01] <mattltm> Not much. Been on the radio most of today. Had a chat with a Maritime Mobile station and a few girl guides on the air.
[21:01] <MrCraig> well chat is good
[21:02] <mattltm> Sure is :)
[21:02] <MrCraig> especially when you're not paying BT for it
[21:02] <mattltm> Lol
[21:02] <mattltm> Hows the self hosted wordpress going?
[21:04] <MrCraig> Ahh - it's worked out quite well - I have regular subscribers - around 20 or so but it's growing slowly. The statistics through google analysis and I can edit, post and view stats all from my android... I've still to sort out the half broken theme though
[21:04] <mattltm> Good. Nothing like hosting it yourself :)
[21:05] <MrCraig> yeah - well I figured I have a server that I pay a monthly subscription for - might as well make use of it :)

[21:06] <mattltm> Sure. I can always help you out with a dedicated box if you get stuck :)
[21:06] <MrCraig> dedicated box?
[21:06] <mattltm> Server

[21:07] <mattltm> Got a whole bunch of 2.8Ghz P4 with 1Gb ram and 80Gb HD sitting in the rack in the data center
[21:07] <MrCraig> ahh no it's cool - I've had this windows server for a couple of years. Hosted in a datacenter and all - it's supporting a handful of websites and perfectly stable and all.
[21:07] <mattltm> Use them as my play things :)
[21:07] <MrCraig> oh wow, a bunch?
[21:08] <mattltm> Ther are blade servers that we recovered form a stock trading room.
[21:08] <mattltm> 24 in total.
[21:08] <mattltm> http://packethub.com/ runs on one
[21:08] <MrCraig> that's cool :-) Clustered data crunching
[21:09] <MrCraig> awesome :-)
[21:09] <MrCraig> you've got them sitting in rackspace's data center?
[21:09] <mattltm> Built a beowulf clusterwith 8 of them last week :)
[21:10] <rjharrison_> Upu Cool tape links
[21:10] <rjharrison_> I'm going to have to order some stuff from there
[21:10] <MrCraig> sweet - I was working on a beowulf cluster too a few years back - they were modified original xboxes. All gone now, I just have the one xbox left running linux as a nas drive

[22:33] <Upu> yeah no problems rjharrison_ I have a yagi if we can't pick it up on the whip
[22:33] <Upu> still chuffed to bits you could pick it up there
[22:34] <Upu> sorry been watching a film
[22:36] <NigeyS> upu
[22:37] <NigeyS> that tape..
[22:37] <Upu> yeah
[22:37] <NigeyS> 1 roll works out as 17quid! lol
[22:37] <Upu> yeah it wasn't cheap I think I got 2 rolls for £24
[22:37] <NigeyS> its that 6quid delivery that kills it!
[22:38] <NigeyS> however found some acrylic paint, 99p! for 59ml
[22:38] <Upu> all I can say is its great to work with :)
[22:38] <Upu> fair enough :)
[22:39] <NigeyS> wonder how the lassens doing outside, put it on the roof, might get a bloody lock there!
[22:39] <Upu> I use this Inventek ISM300 which is suppose to be rubbish, no one seems to rate them but they lock within about 5 seconds of being powered on, get satellites indoors etc
[22:40] <NigeyS> dam thats good, this lassen is evil, 2 sats, and thats outside with a clear unobstructed sky
[22:41] <Upu> and they are only £22 a pop *
[22:41] <NigeyS> i do have a locosys which i got for a pico flight, thats excellent, 6 sats inside in under 5 secs, but its cocom limited :(
[22:41] <Upu> * Horrible surface mount soldering nightmare + transatlantic delivery + customers = meh
[22:41] <NigeyS> hehe ouch
[22:42] <Upu> honestly amazed it still works was convinced we'd cooked it
[22:42] <NigeyS> lol, is it the c3 or c4 type ?
[22:42] <Upu> http://ava.upuaut.net/files/avafc.jpg
[22:42] <Upu> don't know the difference
[22:42] <Upu> what's C3/C4 ?
[22:43] <NigeyS> http://www.inventeksys.com/html/gps_modules.html
[22:43] <NigeyS> bottom 2
[22:43] <Upu> oh C4 sorry
[22:43] <NigeyS> nice pcb dude!
[22:43] <Upu> high altitude build
[22:43] <Upu> not perfect but it works
[22:43] <NigeyS> as long as it works :D
[22:44] <Upu> indeed
[22:44] <NigeyS> trying to do my own but meh eagle hates me
[22:44] <Upu> yeah it is a bit of a fight
[22:44] <Upu> note by the sma connector on the NTX2 there is a little line linking the GND pins
[22:44] <Upu> I could never get rid of it :)
[22:45] <Upu> it wasn't a problem but it just didn't need to be there
[22:45] <NigeyS> oh yeah, ive seen that on the board tim did for the ntx2 aswell
[22:46] <NigeyS> brb go rescue the lassen from the roof and see if its picked up a lock, wish theyd add a dam led to it!
[22:46] <Upu> have fun
[23:04] <NigeyS> yey got a lock
