[00:18] <SpeedEvil> it's irrelevant
[00:18] <SpeedEvil> the size of address that is
[00:18] <SpeedEvil> the important thing is the size of the type of address
[00:18] <SpeedEvil> sizeof(*address)
[00:18] <Laurenceb> u32 address;
[00:19] <SpeedEvil> It should also be objecting about poitners and integers.
[00:22] <Laurenceb> it seems to work now, I got rid of that
[00:22] <Laurenceb> http://wiki.ukhas.org.uk/code:i2c_eeprom
[00:23] <Laurenceb> this should now support up to 512KB of eeprom
[00:23] <Laurenceb> or FRAM for that matter
[00:23] <SpeedEvil> I suppose you're not interested in spelling in comments :)
[00:24] <SpeedEvil> The delays on large writes won't cause you problems elsewhere?
[00:24] <Laurenceb> no
[00:25] <Laurenceb> as it wont block interrupts
[00:25] <Laurenceb> its only 3ms for a page write
[00:26] <Laurenceb> basically you can paint the eeprom with magic number at the start of every record
[00:27] <Laurenceb> then find_top will find where your last record is
[00:27] <Laurenceb> there a 32 bit address space that spans page, block, and device boundaries
[00:27] <Laurenceb> so you could have a bus with several devices on... I hope
[00:28] <Laurenceb> the problem is the code hogs the bus
[00:28] <Laurenceb> nothing else can use the bus with the present code
[00:31] <Laurenceb> it keeps the bus open and only relinquishes control if its necessary to switch block or device

[00:32] <fnoble_> hi edmoore
[00:32] <Laurenceb> that made the write routine nicer, as the data is all internally buffered into the EEPROMs page memory
[00:32] <Laurenceb> hi ed
[00:32] <edmoore> hello
[00:32] <Laurenceb> then written when a page boundary is crossed
[00:33] <edmoore> just about to go to bed. been in library too long.
[00:33] <fnoble_> edmoore, the traking software is looking really fit now
[00:33] <edmoore> fnoble_: have procurred use of a usb bus analyser
[00:33] <edmoore> super useful, just about got my head around the protocol now
[00:33] <Laurenceb> grooo
[00:33] <fnoble_> edmoore, oh sweet
[00:33] <Laurenceb> rather you than me :P
[00:33] <edmoore> so we can nail badger
[00:33] <fnoble_> edmoore, what is this for? the badger?
[00:33] <fnoble_> ok
[00:34] <fnoble_> edmoore, can you please find the handheld gps for saturday?
[00:34] <edmoore> the software tells you the meaning of every byte and if there's an error and whatnot
[00:34] <fnoble_> awesome
[00:34] <edmoore> i have found it
[00:34] <edmoore> in that I have never not found it
[00:34] <fnoble_> ok, good, does it have a compass built in?
[00:34] <edmoore> yes, though I think the compass is actually pretty shit
[00:34] <fnoble_> well you told me you lost it
[00:35] <fnoble_> ok, maybe we should pick up an old school one
[00:35] <fnoble_> analogue

[00:35] <fnoble_> would improve our chances of seeing one land
[00:35] <edmoore> they're much better
[00:35] <edmoore> i would say yes, def
[00:35] <fnoble_> yeah, i know
[00:35] <edmoore> do you know if henry's splurge has arrived?
[00:36] <fnoble_> dont know
[00:36] <fnoble_> i phoned him earlier and he didnt mention it
[00:36] <edmoore> ok
[00:36] <edmoore> right, I am going to head to bed unless there's AOB.
[00:36] <edmoore> can do pcb this w/e as it's far less crap than the week
[00:36] <fnoble_> erm, no i think thats it
[00:36] <edmoore> my week of hell finishes with the 2 lab reports i need to hand in on friday
[00:36] <fnoble_> yeah, i should be more free then
[00:37] <edmoore> right, cya
[00:37] <fnoble_> ok, bye
[00:37] <edmoore> fnoble_: are we going to tag in with henry still or is it too late?
[00:37] <edmoore> for pcb
[00:37] <fnoble_> not too late
[00:37] <edmoore> ok
[00:37] <fnoble_> he has yet to get his act together either
[00:38] <edmoore> mentioned to steve about throwing on some of his things
[00:38] <fnoble_> really want to crack this damn sd card before sat too
[00:38] <fnoble_> on saturday? would be cool
[00:38] <fnoble_> whats he got to send up?
[00:38] <edmoore> no, i mean his thing for the thing
[00:38] <edmoore> the thing he's building for the thing
[00:38] <edmoore> so we can hear the thing
[00:38] <fnoble_> oh right yes
[00:38] <fnoble_> his thing is ready?
[00:39] <edmoore> more or less
[00:39] <edmoore> he said it could be by the weekend
[00:39] <fnoble_> tres excitant
[00:39] <edmoore> would be fun to get made up as we'd be good to roll then
[00:39] <edmoore> just mechanics left
[00:39] <fnoble_> (which is 90% probably)
[00:39] <edmoore> at least :)
[00:39] <fnoble_> i mean we need the big thing to carry the smaller thing
[00:39] <edmoore> mega KISS effort and we'll be fine
[00:40] <edmoore> the big thing is the bulk of thinging left to thing
[00:40] <fnoble_> yeah, at least we will be making progress
[00:40] <edmoore> how is the elec-thing to power the thing to make the big thing?
[00:40] <fnoble_> so we need to get herny to finish the control thing for the thing making think
[00:40] <fnoble_> *thing
[00:40] <edmoore> the thing-a-tron
[00:41] <edmoore> we need a url too that is very memorable
[00:41] <edmoore> so people can using a thing to track the thing
[00:41] <fnoble_> www.cuspaceflight.co.uk ?
[00:41] <edmoore> details
[00:41] <edmoore> well was thinking more general and ukhasey
[00:41] <fnoble_> www.cuspaceflight.co.uk/thing
[00:41] <edmoore> switch to #thing quickly
[00:41] <edmoore> by which i mean not actually '#thing'
[00:41] <edmoore> but thing
[00:42] <Laurenceb> are you talking about the *item removed for national security* ?
[00:42] <edmoore> that thing yes
[00:43] <Laurenceb> SpeedEvil: what do you think to that code?
[00:43] <Laurenceb> reacon it will work?

[19:24] <natrium42> hi
[19:25] <rjharrison> Hi natrium42. Have got ny callsign through. We should have a go at radioing through the internet one day
[19:25] <fnoble_> edmoore, you called?
[19:25] <rjharrison> fnoble_ Did you get your thing to work?
[19:25] <fnoble_> which thing?
[19:26] <natrium42> rjharrison, cool, congrats
[19:26] <edmoore> fnoble_: can't remember why
[19:26] <rjharrison> I'm not sure I got a bit lost last night
[19:26] <edmoore> actually
[19:26] <edmoore> are you around this eve?
[19:26] <fnoble_> the tracking thing?
[19:26] <fnoble_> edmoore, depends for what

[19:27] <rjharrison> Yep, I looked through the logs and there seemed to be alot of things on there :-P
[19:27] <fnoble_> the tracker is making progress, it was always working, but ive got the landing prediction working with it now
[19:27] <rjharrison> Excellent it looked impressive last w/e
[19:28] <fnoble_> yeah, but our yagi/decoding setup didnt seem to be getting as much as james
[19:28] <fnoble_> also it uses a crute method for finding strings
[19:28] <fnoble_> it kinda needs them to be on their own line
[19:28] <fnoble_> which i should improve, but it works with the badger
[19:28] <edmoore> may not if it's as cloudy as poo on sat
[19:29] <edmoore> would be nice to really test it
[19:29] <rjharrison> Is there another launch going up this w/e?
[19:30] <fnoble_> yeah
[19:30] <fnoble_> nothing major

[19:31] <fnoble_> just an up and down affair hopefully to get some pictures for sponsors
[19:31] <rjharrison> 434.650 or .075
[19:31] <Laurenceb> another launch?
[19:31] <fnoble_> and test various things
[19:31] <fnoble_> 650
[19:31] <fnoble_> rjharrison, you might get it through that repeater of yours :)
[19:32] <rjharrison> :) I'm going to put a .075 on my beacon before the next launch
[19:32] <fnoble_> yeah, its a good idea
[19:32] <rjharrison> I have a spare one here if someone wants to change the badger
[19:33] <fnoble_> well we havnt had any problems so far...
[19:33] <natrium42> fnoble_, cusf?
[19:33] <natrium42> when is it?
[19:33] <fnoble_> yeah, cusf, and saturday
[19:33] <fnoble_> dont know the time yet
[19:34] <rjharrison> Cool, my guess is that no bugger can work out the rtty and even if they did they wouldn't be able to follow it back
[19:34] <natrium42> nice, good luck
[19:34] <edmoore> the wind isn't supertastic for saturday
[19:34] <fnoble_> no, its not
[19:34] <fnoble_> a few hour launch window around 12
[19:35] <rjharrison> From Churchill
[19:35] <fnoble_> yup
[19:35] <Laurenceb> theres something every weekend :D
[19:35] <fnoble_> today otoh had brilliant winds
[19:35] <edmoore> may have to go for a clippy ascent
[19:36] <natrium42> you have asked for me? http://bananasfk.files.wordpress.com/2007/03/clippy.jpg

[19:37] <rjharrison> Very good natrium42
[19:38] <rjharrison> haha

[19:38] <rjharrison> That is a great button
[19:38] <natrium42> duh
[19:39] <fnoble_> edmoore, you never answered, what did you have in mind this evening?
[19:40] <edmoore> well i have to do a lab report then go to the gym. was wondering if after that you fancied a PCB/ham-cram
[19:40] <rjharrison> You're not going to play with your things again
[19:40] <edmoore> but it depends on how quickly i can write up this report
[19:40] <fnoble_> well, i have a few things im supposed to be doing
[19:41] <fnoble_> wouldnt be till 10 or 11 i was free
[19:42] <edmoore> no chance of me being done by then anyway :)
[19:43] <fnoble_> ok, ill see how it goes
[19:43] <fnoble_> epends weather i end up going out to see this play a friend is in
[19:47] <edmoore> i would probs do that anyway. I think I may be in for the long haul.
[19:47] <fnoble_> ok
[19:47] <edmoore> saturday at 12 is not great
