[00:01] <arko> anyone recommend a flow regulator for helium?
[00:02] <arko> that measures

[00:04] <arko> i mena flow meter
[00:09] <gonzo__> most people go by the neck lift
[00:09] <gonzo__> rather than the vol of gas
[00:09] <arko> yeah
[00:09] <arko> i have that
[00:10] <arko> a scale to measure neck lift
[00:12] <Randomskk> flow meters are hideously expensive
[00:12] <Randomskk> like $$$$ to $$$$$
[00:12] <Randomskk> for helium at even low flow rates
[00:13] <Randomskk> http://www.bronkhorst.co.uk/ make suitable ones
[00:13] <Randomskk> they are not cheap

[00:14] <chrisstubbs> arduino question: my code does not catch all of the serial buffer coming into tinygps. it works if i comment out rtty_txstring()
[00:14] <chrisstubbs> is there a way to increase the buffer, or make it read it as it comes in as well as transmit
[00:15] <chrisstubbs> using hardware serial
[00:15] <arko> i just wanted one so i didn't have to keep taking it off and on the filling station
[00:15] <arko> to adjust neck lift
[00:16] <Darkside> chrisstubbs: which gps are you using?
[00:16] <Darkside> because using polled mode might work better
[00:16] <chrisstubbs> right now just piping NMEA down serial monitor
[00:16] <chrisstubbs> ok yeah i see what you mean
[00:18] Habjoe (~Habjoe@83.2.189.80.dyn.plus.net) left irc: Ping timeout: 245 seconds
[00:19] <chrisstubbs> it only catches the first 63 chars of the string, becuase of the 64 byte buffer i guess
[00:20] <arko> Randomskk: i guess a flow meter and a stop watch is enough
[00:20] <Randomskk> I would use neck lift, really
[00:20] <arko> yes absolutely
[00:21] <arko> but to hit the target neck lift
[00:21] <arko> i just dont want to be going back and fourth a lot
[00:21] <Randomskk> I mean, use the scales
[00:21] <Randomskk> you shouldn't have to go back and forth?
[00:21] <arko> what do you mean?
[00:21] <Randomskk> when we fill with the scales, we just have the scales on the fill pipe
[00:21] <Randomskk> and measure until we're good
[00:21] <Randomskk> then turn off the valve

[00:24] <gonzo__> if the fill tube is not too heavy, you can leave it on when measuring the lift. But you still have to add the fill tube weight to the calc
[00:24] <Randomskk> exactly
[00:24] <gonzo__> snap
[00:25] <arko> cool
[00:25] <arko> makes sense

[00:25] <arko> that foam is ok to use?
[00:26] <arko> the inside

[00:26] <Randomskk> yea

[00:27] <Randomskk> I have a dnd naming scheme for computers
[00:27] <arko> cool, just wondering
[00:27] <Randomskk> it's not like I even play dnd any more
[00:27] <Randomskk> just it's a handy scheme
[00:27] <Randomskk> arko: yea it works well
[00:27] <Randomskk> nice being able to tear off different sizes
[00:27] <arko> excellent
[00:27] <arko> yeah,i bought a few pelican cases recently :D
[00:27] <arko> time to tear into them

[00:32] <Randomskk> why do you know this stuff
[00:32] <Darkside> he probably just googles it on demand
[00:33] <mfa298> fsphil: reading scrollback, I think some of the earlier RPi boards (and possibly current ones) had various e-fuses that would effectivly limit the current usb devices could draw meaning some devices had issues.

[02:18] <nigelvh> Randomskk, I figured out why my readings were so crappy.
[02:18] <nigelvh> Apparently the toroids I have are designed for power filtering, and just attempt to suck everything but DC.
[02:19] <nigelvh> I can get them to give me values I want, but the Q is always 1 or 2
[02:19] <nigelvh> Got some other toroids in the mail, so hopefully those will be better.

[11:20] <Hix> red LED == Good!!! http://i.imgur.com/HT6iDFG.jpg
[11:20] <Hix> Tracker pretty much done, just waiting for Royal Fail to deliver MAX6 and NTX2 and it's all done
[11:20] <fsphil> red LED at night, hackers delight
[11:21] <Hix> TQFP wasn't that shocking, couple of stubborn bridges but sorted in the end
[11:21] <Hix> http://i.imgur.com/FCTiDTO.jpg bridge fail
[11:22] <joph> do you have flux?
[11:22] <fsphil> bridges are perfectly normal
[11:22] <fsphil> flux + braid, and a touch of the iron, is usually enough to get rid of them
[11:22] <fsphil> that's pretty good soldering
[11:22] <Hiena> Flux it, smear it, braid it.
[11:22] <Hix> got flux, as you can see by the sticky mess on pcb, they are a pain to get shot of fsphil
[11:23] <fsphil> need some cleaning fluid
[11:23] <Hix> anything to use in it's absence?
[11:23] <Hiena> Isopropil, tequila, whatewer over 40%.
[11:24] <Hix> hmm, got some alcohol screen cleaner, I'll try that on a bud
[11:24] <fsphil> isopropyl alcohol, it's often found in first aid kits
[11:25] <Hiena> Also some paint thinners works.
[11:25] <fsphil> rubbing alcohol I think is another name for it
[11:25] <Hiena> Screen cleaner usually too weak to remove the flux, but worth a shot.
[11:26] <Hix> there was a wee bit too much on the first two pins, but it was ok, i erred on the side of caution rather than trying to remove it http://i.imgur.com/C6w8HI5.jpg]
[11:26] <fsphil> the braid shouldn't remove all of it
[11:27] <Hix> it had bridged and then gone underneath the pins

[11:28] <Hix> but for my first board, not too shabby i don't think

[11:52] <mfa298> reading back a bit you can get 1L tins of isopropyl alcohol (I've often seen it shorted to IPA) at maplin for about 15 quid. well worth the investment
[11:53] <Hix> I'll just obtain some from work, for now computer screenwipe fluid has cleaned most of the sticky residue up
[11:54] <chrisstubbs> hix i use acetone (nail varnish remover)
[11:54] <chrisstubbs> not quite as good as IPA but works
[11:54] <Hix> ahhh, thinkin tex
[11:59] <Hix> well that's positive, the sketch uploaded to the board first try :D
[12:00] <chrisstubbs> wow
[12:00] <Hix> that USBTinyISP thing is shite - buy once, buy right :/
[12:00] <chrisstubbs> if your going anything like as well as me the sketch wont run for at least a day
[12:01] <Hix> should be good, it's been tested a lot on the breadboard and the pcb is the same, so here's hoping
[12:01] <Hix> just need Royal Fail to deliver my MAX6 and NTX2 now :/
[12:01] <chrisstubbs> Hix are you using hardware serial and tinygps?
[12:02] <chrisstubbs> yeah im waiting on my NEO6, didnt realise it was from china
[12:03] <Hix> yes, HW with TinyGPS, though is a bit crap as lat and lon are floats
[12:03] <Hix> need to improve the sitch
[12:04] <chrisstubbs> are you using standard NMEA or ubxtinygps?
[12:04] <Hix> std NEMA to the best of my knowledge, forst i've heard of uxbtinygps
[12:04] <chrisstubbs> ooh
[12:05] <chrisstubbs> can i have a peek at your code?

[12:08] <Matt___> hey all
[12:09] <fsphil> howdy matt
[12:09] <Matt___> I come in search of a code guru....
[12:10] <Matt___> After attending the 2012 UKHAS conference I went away with every intention of having a go at a launch this year...
[12:10] <Matt___> Im a programming newbie
[12:10] <Matt___> but got loads of info from the wiki
[12:11] <Matt___> particularly $$Bob payload info
[12:11] <Matt___> Until last week, I had a payload working perfectly
[12:11] <Matt___> UBLOX, NTX2, Arduino.... the usual
[12:11] <fsphil> nice
[12:11] <Matt___> BUT......
[12:11] <fsphil> waiting for that bit :)
[12:12] <Matt___> I started messing with the code to integarte some temp sensors
[12:12] <Matt___> It didnt work, so I thought Id reload the old code
[12:12] <Matt___> firstly ....
[12:12] <Matt___> I kept getting a "not in sync" error during upload
[12:13] <Matt___> yes - I know.... Ive checked the port, board etc
[12:13] <Hix> disconnenct ublox from hw uart
[12:13] <Hix> or use icsp
[12:13] <Matt___> long story short - if I disconnect the UBLOX from the Arduino that message goes away
[12:13] <fsphil> that's it
[12:13] <Matt___> But now....
[12:13] <Matt___> whatever I do
[12:13] <Hix> you cant use arduino with hw serial attached
[12:14] <Matt___> and even uploading the original code which Im 100% was working....
[12:14] <Matt___> I get just one RTTY line on fldigi waterfall.... so I used the debug output to see what was going on...
[12:14] <Matt___> and I get this....
[12:15] <Matt___> Loop() Start Main loop
[12:15] <fsphil> your code might not do anything if there's no gps data being received
[12:15] <Matt___> Loop() Dont go around this loop more than once every 5 seconds
[12:15] <Matt___> Loop() Request Navigation Data from GPS module
[12:15] <Matt___> $PUBX,00,235958.00,0000.00000,N,00000.00000,E,0.00,NF,5303301,3750000,0.000,0.00,0.000,,99.99,99.99,99.99,0,0,0*2A
[12:16] <Matt___> Loop() ERROR Timed out in Serial.available
[12:16] <Matt___> .... and round and round it goes
[12:16] <fsphil> is your ublox wired the correct way?
[12:16] <Matt___> I know the Ublox is Ok as I uploaded the basic code that lets you view the NMEA output
[12:17] <Matt___> 0V, 5V, Tx, Rx
[12:17] <fsphil> check your rx/tx pins
[12:17] <Hix> try reversing just in case
[12:17] <Matt___> Ive tried it both ways just incase that was an issue!
[12:17] <Matt___> great minds think alike : )
[12:17] <Hix> we've all been there
[12:17] <Hix> i hope :)
[12:17] <Matt___> Is this the bit I need to be investigating?..... - Loop() ERROR Timed out in Serial.available
[12:18] <Hix> i have certainly
[12:18] <fsphil> receiving gps data on the usb uart might mean the gps tx is wired to the avr's tx pin
[12:18] <Matt___> My Ublox is wired to pins 0 & 1 on the Uno
[12:19] <Hix> which one goes to 0
[12:19] <Matt___> The thing is guys - this WAS working perfectly for so long. Its actually a charity launch that I hope to do nearer the summer... but Im feeling the pressure with issues like these
[12:19] <fsphil> the GPS TX pin should go to the RX arduino pin
[12:19] Action: Hix nods
[12:20] Action: chrisstubbs laughs at Hix's code commenting
[12:20] <Matt___> Silly question - lets say it was the wrong way round..... would that make anything go splat?
[12:20] <fsphil> just make it not work
[12:20] <Hix> chrisstubbs: the pause comment maybe?
[12:21] <fsphil> the avr chip wouldn't receive any data from the gps unit
[12:21] <Matt___> pause comment?
[12:21] <fsphil> and it may wait forever, or timeout, which is the error your seeing
[12:21] <chrisstubbs> yeah thats the one, for flight mode ;)
[12:21] <fsphil> you're*
[12:22] <Matt___> Gotchya.. but after putting them back the correct way - would there now be permanent damage
[12:22] <fsphil> IRC should have a feature for correcting already transmitted lines :)
[12:22] <fsphil> unlikely
[12:22] <Matt___> phew
[12:22] <fsphil> swapping the voltage pins around might damage something
[12:22] <Matt___> spot the newbie ! : )
[12:23] <Matt___> pretty sure I havent messed voltage polarity
[12:23] <fsphil> your ublox module, is it 5v tolerant?
[12:23] <Hix> chrisstubbs: it was back when i didn't know what was going on so i let the ublox come to terms with it and work it out itself :D
[12:23] <Matt___> Yes, its the Arduino 5V compatible version
[12:24] <fsphil> it's possible that might get damaged backwards
[12:24] <Matt___> Really!?
[12:24] <fsphil> depending on how it was wired
[12:24] <fsphil> the TX line from the ublox (3.3v) might not have any protection on it
[12:25] <fsphil> as the avr (5v) can accept 3.3v signals
[12:25] <Hix> is it Upu's board?
[12:25] <Matt___> Upu? ....sorry
[12:26] <Hix> HAB Supplies
[12:26] <Matt___> Yes
[12:26] <Hix> ah oki
[12:26] <Matt___> If it WAS knackered though, I wouldnt get the NMEA strings like I am in test mode, would i?
[12:27] Habjoe (~Habjoe@190.172.189.80.dyn.plus.net) joined #highaltitude.
[12:27] <Matt___> Guys... Just going back to the "not in sync" error I experienced during code upload, which went afetr removing the UBLOX...... Is that normal?
[12:28] <fsphil> I find it strange that you're seeing gps strings, unless your program is setup to repeat them?
[12:28] <fsphil> yes
[12:28] <fsphil> the ublox is on the same hardware uart as the programmer
[12:28] <Hix> yeah, the arduino uses the sam epin to upload the sketch
[12:28] <Hix> what he said :)
[12:28] <Matt___> And it kinda blocks it?
[12:28] <fsphil> basically
[12:28] <Hix> yup
[12:28] <Matt___> Cool
[12:29] <Hix> or not - depending on if its soldered or not :)
[12:29] <fsphil> I guess the gps module would have rx isolation too, otherwise programming it would have damaged it
[12:30] <Matt___> if you say so : )
[12:30] <fsphil> but I still believe it's wired up backwards
[12:30] <fsphil> unless your repeating the gps data in your code
[12:31] <Matt___> You know what - youve made me really paranoid now.... Im going to have to go and triple check that!
[12:31] <chrisstubbs> if its tinygps there is a function to do that
[12:31] <fsphil> can you take a picture?
[12:31] <Matt___> I may return red faced
[12:31] <Hix> did you follow this Matt___ http://ava.upuaut.net/store/wiki/doku.php?id=levelconvertor
[12:31] <fsphil> uart dyslexia is a common problem :)
[12:32] <Matt___> Yes I did, to see if Id killed the module. And after uploading that code and running U-Centre, it seemed to be working fine
[12:32] <Hix> speaking of that wiki what are these clips called http://goo.gl/F4QOH
[12:32] <Hix> i need me some of those
[12:33] <fsphil> if u-centre was showing good data, then the module is likely fine
[12:33] <fsphil> ic hooks
[12:33] <Matt___> thats what I thought
[12:33] <fsphil> yea they're great
[12:33] <Matt___> will go and check tx/rx polarity....
[12:33] <Hix> ah cool
[12:33] <Hix> cheers fsphil
[12:34] <Hix> always difficult searching for something you don't know name of :)
[12:37] <Matt___> Ok....
[12:37] <Hix> ahh, two fer a paand two fer a paaand, as they say round ere http://goo.gl/oWSgl
[12:37] <Matt___> Go figure....
[12:38] <Matt___> tx & rx were the opposite way to how you described ... BUT - I am almost positive thats how they were when working
[12:38] <Matt___> However - Im still getting an error on the degug console...
[12:38] <Matt___> This may make more sense to some of you now
[12:38] <Matt___> Permission to put it up on here?.....

[12:46] <fsphil> yea but that's not much help
[12:46] <Matt___> ah : (
[12:46] <fsphil> so your ublox tx is now going to the arduino rx?
[12:47] <Hix> paste the code you are using there too Matt___
[12:47] <Matt___> It seems to initialise and set parameters Ok, then when it gets to that part it just goes round and round there
[12:47] <fsphil> there's also the chance that your debug code is interfering

[12:54] <Hix> just a thought Matt___ have you tried it at 4800 baud?
[12:55] <Matt___> No
[12:55] <Matt___> you think its worth a try?.... could you see any other obvious issues with the code?
[12:56] <Hix> i remember something about 4800 ironing out some woes, worth a shot it's a qiuck thing to change
[12:56] <Hix> reading through now, though I am at a basic level
[12:57] <Matt___> Ditto!
[12:57] <Hix> give it a shot, may be an easy win
[12:57] <Matt___> Ill be honest... thats pretty much a Copy/Paste from $$Bobs payload - except Ive printed it and tried to understand it line for line
[12:59] <Matt___> Do i change the GPS to 4800, or the software serial debug output to 4800?
[12:59] <Hix> both
[13:00] <Matt___> ok : )

[13:03] <Hix> in fact my current working code doesn't have them at all
[13:03] <Matt___> Really!? Ill do that now. Ive just changed to 4800

[13:05] <Hix> oki, tried 76-86 yet?
[13:06] <Matt___> do you mean completely remove them?... or proceed them with // ?

[13:07] <Hix> if you see what i mean
[13:08] <Matt___> ok
[13:11] <Matt___> Thanks for the suggestions hix, but still getting same output as here....http://pastebin.com/ZS3cRLJC : (
[13:13] <Matt___> The closest this things gonna get to "near-space" is when I lauch it out of my window in the direction of the nearest tree!
[13:13] <Hix> oki, I'm thinking that it may be trying to do stuff straight away after setting nav mode
[13:13] <Hix> so
[13:14] <Hix> new line after #96 [getUBX_ACK(setNav);
[13:14] <Hix> and add

[13:15] <Matt___> Shall I undo last 2 mods that we did?
[13:15] <Hix> not yet, can reintroduce thinhgs as and when working
[13:18] <Matt___> did you mean to put a [ in the first line?
[13:18] <Hix> no
[13:19] <Matt___> ok

[20:06] <fsphil> ah, Bill got a position
[20:06] <fsphil> it's in a tree :(
[20:07] <nigelvh> Yay trees!
[20:07] <fsphil> very tall trees from the looks of it
[20:07] <Lunar_Lander> Bill = WB8ELK?
[20:07] <fsphil> ah, all the roads have an Austrlian theme
[20:07] <fsphil> Outback Road, Koala Road
[20:08] <fsphil> nearest road is Phil "That's not a tree!" Dundee Way
[20:08] <Lunar_Lander> XD
[20:08] <Lunar_Lander> does WB8ELK fly?
[20:08] <fsphil> he did
[20:08] <fsphil> now landed
[20:08] <Lunar_Lander> :)
[20:08] <Lunar_Lander> cool
[20:08] <fsphil> annoying some squirrels
[20:09] <Lunar_Lander> xD
[20:09] <Lunar_Lander> which modes did he transmit in?
[20:10] <fsphil> rtty, dominoex and aprs
[20:12] <Lunar_Lander> cool
[20:12] <Lunar_Lander> is dominoex difficult with arduino and NTX2 btw?
[20:13] <fsphil> not nearly as simple as rtty
[20:14] <Lunar_Lander> ohhh
[20:14] <Lunar_Lander> :(

[20:21] <Laurenceb_> that place looks more like a cinema
[20:22] <Lunar_Lander> cool Geoff-G8DHE
[20:24] <Geoff-G8DHE> Only grabs from GE, I just find that looking at the paths in GE is more informative than on a flat map ;-)
[20:25] <Geoff-G8DHE> Any idea who looks after the dl-fldigi code ?
[20:25] <fsphil> the guys in #habhub
[20:26] <Geoff-G8DHE> Nobody around much at present but I'll ask !
[20:27] <fsphil> ah, what's the question?
[20:28] <Geoff-G8DHE> I just wondered if they had clocked the new'ish DDE interface for SDR# which includes frequency control, its been written for the Wx sat guys by Ian Gilmour
[20:29] <Geoff-G8DHE> http://www.satsignal.eu/software/DDETracker.html
[20:29] <Geoff-G8DHE> Just wondering if fldigi could be modded to include use the same interface, he has already added a couple of different ones to the client interface.
[20:30] <Geoff-G8DHE> Make life a lot easier for tracking drifting signals, especially overnight!
[20:31] <fsphil> dde is pretty useless outside of windows sadly
[20:32] <fsphil> ideally we need some way of doing it over standard IP sockets
[20:32] <fsphil> and a method that all the sdr apps support
[20:32] <Geoff-G8DHE> Any tool is better than none ..
[20:33] <fsphil> better again would have it supported in hamlib
[20:33] <fsphil> then any app can use it
[20:34] <Lunar_Lander> thanks again for preparing that for my ascent Geoff-G8DHE
[20:35] <Geoff-G8DHE> No problem, if you want any other views shout, its not a problem to produce <Lunar_Lander>
[20:35] Action: fsphil is talking to the linksprite

[20:35] <Lunar_Lander> fsphil, you do?
[20:35] <Lunar_Lander> that thing still pulls my hair out
[20:35] <fsphil> well it's answering my reset command anyway
[20:36] <fsphil> not got as far as actually taking pictures yet
[20:36] <Lunar_Lander> yea
[20:36] <Lunar_Lander> do you call it from an AVR?
[20:36] <fsphil> yea
[20:37] <Lunar_Lander> ah
[20:37] <Lunar_Lander> arduino?
[20:37] <fsphil> 644p
[20:37] <Lunar_Lander> :) cool
[20:37] <fsphil> it's sending more data than I expect
[20:39] <Lunar_Lander> yeah
[20:39] <Lunar_Lander> do you have a 5V FTDI?
[20:39] <fsphil> nope

[20:43] <arko> afternoon gentlemen
[20:43] <fsphil> right, it sends text after it resets

[20:47] <arko> haha
[20:48] <fsphil> I am the alpha *and* the omega
[20:49] <nigelvh> I have to say as a side note, this channel does seem to have a lot of odd conversations.
[20:49] <fsphil> maybe helium is not as inert as we once thought
[20:49] <nigelvh> Entirely plausible
[20:50] <arko> this channel does not have odd conversations as much
[20:50] <arko> i do enjoy that about it
[20:51] <nigelvh> This is a great channel
[20:59] <fsphil> how far did you get with the camera Lunar_Lander?
[20:59] <fsphil> it seems to have composite output too. not sure what to use that for

[22:03] <fsphil> hehe, dell
[22:04] <arko> yeah
[22:04] <arko> 2950
[22:04] <fsphil> that's a lot of stuff
[22:04] <arko> made a vm that allows you to create a hourly instance
[22:04] <fsphil> they looks to be the same models as our old servers
[22:04] <arko> multiple hourly instances
[22:04] <arko> yeah.. all that
[22:04] <arko> was like less than a grand
[22:04] <arko> USC was selling them when they upgraded
[22:05] <arko> some of them are actually stupid powerful
[22:05] <fsphil> I'm considering taking ours when they're retired
[22:05] <fsphil> but they're noisy buggers
[22:05] <arko> and panasas
[22:05] <arko> for 40TB of data storage
[22:05] <arko> and we have fiber line
[22:06] <arko> i was hoping to get this vm interfaced to the web interface so people could start up their own hourly

[22:09] <arko> i dunno, or just buy tickets and move to the uk
[22:17] <fsphil> or we could all go over there :)
[22:17] <fsphil> or lots of remote stations that can be controlled remotely

[23:01] <arko> hah, it would have been cool if it landed in Roswell a little south from there
[23:04] <fsphil> this is weird. I have an if() statement, the result of which is false. but the else code is never executed

[23:21] <jonsowman> lol
[23:22] <fsphil> it was quite silly. my if() was never executed again because there was no more data coming in from the uart
[23:23] <fsphil> it worked the first time because in that case some extra data was transmitted
[23:23] <fsphil> now I have to make my code ugly to fix it
[23:23] <jonsowman> :)
[23:23] <jonsowman> at least it's not picaxe etc
[23:24] <fsphil> indeed
[23:25] <gonzo_> I had some loops that did that in my first tracker. The foreground is in a loop waiting for a flag to change to say there is a nmea packe in the buffer. would just hang the whole thing (and never get to the bit that periodically sends the gps refresh command)
[23:25] <gonzo_> put an extra get out of jail free count
[23:26] <fsphil> in this case it had just received two bytes describing the amount of data to follow
[23:27] <fsphil> but if that was zero bytes, it still had to wait on another byte before the test for zero happened
[23:27] <fsphil> just learned some C: if(0) if(1) printf("Hello!"); else printf("World!");
[23:28] <fsphil> prints nothing
[23:28] <fsphil> the else relates to the nearest if()
[23:28] <gonzo_> another fun lin e(that has caught me out more than once)
[23:28] <gonzo_> if (something) ;
[23:29] <gonzo_> the colon goes off the page so you are left wondering why the conditional code always executes, regardless of the condition
[23:30] <fsphil> I'm quite strict with my white space
[23:30] <gonzo_> sometimes one creeps in
[23:30] <fsphil> I'm surprised that doesn't generate a compiler warning
[23:30] <fsphil> useless conditional
[23:30] <gonzo_> easier to see with windows editors. Not so with text/command line editors
[23:31] <gonzo_> C compilers tend to assume you know what you are doing
[23:31] <fsphil> lol
[23:31] <fsphil> even so, nobody sane would write code that way
[23:32] <gonzo_> my old CS lecturer described languages in terms of a chain saw. Pascal was like one brought from B&Q. Lots of guards and protection, but they get in the way of chopping awkward trees
[23:33] <gonzo_> C was an industrial chainsaw. Will do serious work, but get it wrong and you loose an arm
[23:33] <gonzo_> so the common pitcalls, like if ( byByte = 1 )
[23:34] <gonzo_> would be refered to as a whole arm bug. Some smaller ones just cost you a finger
[23:34] <gonzo_> the = was always called a gozinta, not equals
[23:35] <gonzo_> cos this goz'inta' that
[23:35] <gonzo_> make a joke, you remember it!
[23:36] <fsphil> I've done = frequently
[23:38] <gonzo_> usually writes to zero page, so usually just kille the whole system dead. So gets found
[23:38] <gonzo_> I have been bitten so many times, the == is pretty much automatic for me.
[23:38] <fsphil> here too
[23:38] <fsphil> but it still happens
[23:39] <gonzo_> getting == in an asignment does happen though
[23:39] <gonzo_> my compilers woill happily do byByte == 0;
[23:40] <gonzo_> only gets flagged if it thinks you have ysed the var without initialising]
[23:40] <gonzo_> but that depends what comes before
