[00:25] <Laurenceb> I've just got rprintf from procyon avrlib working
[00:26] <Laurenceb> its 1KB smaller than printf
[00:26] <natrium42> cool
[00:26] <Laurenceb> so room for I2C
[00:26] <natrium42> push it to the limit! :P
[00:26] <Laurenceb> and ground control on the mini rogallo now
[00:26] <Laurenceb> yeah
[00:27] <Laurenceb> I'm just writing some I2C code atm
[00:27] <Laurenceb> pity I cant get FRAM
[00:27] <natrium42> bbl
[00:27] <SpeedEvil> Laurenceb: yay!
[00:27] <SpeedEvil> Laurenceb: ground control - for taxiing?
[00:28] <Laurenceb> so you can guide it in for a nice landing
[00:28] <Laurenceb> hopefully it will reach the target with altitude to spare, and start circling, so if there someone there with a 47MHz tx they can guide it down
[00:29] <Laurenceb> basically it just takes the ICP unit and a state machine
[00:29] <Laurenceb> running in an input captine ISR
[00:29] <Laurenceb> *capture
[00:29] <SpeedEvil> You mean go to R/C mode?
[00:29] <SpeedEvil> or fly by wire?
[00:30] <Laurenceb> got to RC mode yes
[00:30] <Laurenceb> tho I could do a fancy fly by wire where you input a target bearing with your stick
[00:31] <Laurenceb> I'm using every single pin on my atmega now
[00:32] <Laurenceb> if I really wanted to take it to the limit, I'd get a little camera and stick a FAT library on the radio to grab jpegs off and SSTV them
[00:32] <Laurenceb> but thats probably not possible without an ARM

[00:43] <Laurenceb> if (((TWSR & 0xF8) != TW_START)&&((TWSR & 0xF8) != TW_REP_START))
[00:43] <Laurenceb> is there a better way to do htat?
[00:44] <Laurenceb> logic soetimes gets me confused...
[00:44] <Laurenceb> TW_START and REP_START are 0x10 and 0x08

[19:21] <natrium42> hi
[19:21] <fnoble> edmoore, hi
[19:21] <natrium42> what's the news?
[19:21] <edmoore> nothing much
[19:21] <edmoore> fnoble: thurs is looking to be subject to the presenter being available
[19:21] <edmoore> darn
[19:22] <fnoble> bugger it
[19:22] <fnoble> could do it anyway
[19:22] <fnoble> or maybe do the parkside launch
[19:22] <edmoore> they're on half term
[19:22] <fnoble> i see
[19:23] <fnoble> so what are the chances of the presenter being free?
[19:23] <edmoore> also college want a lot more hoops jumped through for H&S if there's hoardes of small kids about
[19:23] <edmoore> he didn't give me a number
[19:23] <fnoble> yup
[19:23] <rjharrison> hi edmoore
[19:23] <edmoore> just that he'd get back to me tomorrow morning
[19:23] <fnoble> ok
[19:23] <edmoore> we should do some badger...
[19:23] <fnoble> not until wednesday evening im afraid
[19:24] <edmoore> ok
[19:24] <fnoble> ive got a lot of work to plough through
[19:24] <edmoore> well, do you have the list of things that need to be done?
[19:24] <edmoore> i could at least start on the schematic
[19:24] <fnoble> ive done most of the schematic now
[19:24] <edmoore> i did 1.5 examples papers thisafternoon so I can justify myself some off-time
[19:25] <edmoore> well, i can do some layout then
[19:25] <rjharrison> It looks like the wind is going to be coming from the north over the w/e does that pose a problem for launching?
[19:25] <edmoore> your call, but looking at sat we wouldn't launch from cam
[19:25] <fnoble> rjharrison, are you launching again this w/e?
[19:27] <rjharrison> no
[19:27] <edmoore> fnoble: I will happily do some routing for the next hour or two
[19:27] <rjharrison> there is a lot going on
[19:27] <rjharrison> bbiab
[19:28] <fnoble> edmoore, i'd rather do it together if thats ok
[19:28] <edmoore> ok np
[19:28] <edmoore> i'll try and keep wednesday eve free
[19:28] <fnoble> may be able to do some stuff tomorrow or wed daytime depending on how work goes
[19:29] <edmoore> tomorrow is a pretty good day from my pov
[19:29] <fnoble> ive been at it since 6.30am, still got 1.5 examples sheets to go before i can call it a night
[19:29] <fnoble> :(
[19:29] <edmoore> eeeek
