[00:00] <fnoble> why is it always this time in the evening i find myself trying to recompile gcc :)
[00:05] <edmoore> how do I curl the contents of a folder
[00:06] <edmoore> fnoble: why are you doing that now?
[00:08] <fnoble> want proper gnu gcc to do some OS stuff with
[00:08] <fnoble> rather than crappy xcode gcc
[00:09] <fnoble> well actually, more specifically, I need the gnu ld, as the xcode one doesnt support linker scripts or ELF output
[00:10] <fnoble> whats curl?
[00:11] <edmoore> wget
[00:11] <edmoore> but newer
[00:12] <akawaka> fnoble: you just need to compile binutils then, right?
[00:12] <fnoble> i dont know if xcode gcc is compatable with non xcode binutis
[00:13] <fnoble> so i just got the whole macports i386-elf toolchain

[08:27] <akawaka> awesome
[08:27] <akawaka> just finished adding an ir sensor to my lcd monitor so i can access all the button functions with a remote control
[08:28] <akawaka> thats probably the most complex electronics project i've ever tried without any external guide

[16:35] <jcoxon> anyone around for some advice on making a circuit with a PIC?
[16:37] <akawaka> what kind of advice?
[16:38] <jcoxon> well what pins need to be connected to actually get it to turn on?
[16:39] <jcoxon> VSS and VDD
[16:39] <jcoxon> got them
[16:39] <Laurenceb> PICs ?! blerg
[16:39] <jcoxon> haha, its a rocketboy radio PIC
[16:39] <akawaka> pics rock
[16:39] <Laurenceb> ah cool
[16:39] <jcoxon> so its already programmed
[16:39] <Laurenceb> do you need HV to program a PIC?
[16:39] <jcoxon> am just wiring it up
[16:39] <Laurenceb> I see
[16:40] <jcoxon> i've got all the connections between the radio and the PIC
[16:40] <jcoxon> but i'm not sure what else is needed
[16:40] <jcoxon> do i need to tie the reset line somewhere?
[16:40] <Laurenceb> crystal?
[16:40] <jcoxon> i've got an external one
[16:40] <jcoxon> 3.686
[16:40] <Laurenceb> cool, and caps?
[16:40] <jcoxon> 2 pins
[16:41] <jcoxon> does that literally go between OSC1 and OSC2?
[16:41] <Laurenceb> you'll need caps to gnd off those pins as well
[16:41] <Laurenceb> but the crystal goes inbetween
[16:41] <Laurenceb> 22pf caps
[16:42] <akawaka> microchip have a good doc on osc setup
[16:42] <jcoxon> got 2 of the 22pf caps
[16:42] <akawaka> do you need an external osc?
[16:42] <Laurenceb> your ready to go then :P
[16:42] <jcoxon> rocketboy sent me one
[16:42] <jcoxon> Laurenceb, so do they go between each pin and gnd?
[16:42] <Laurenceb> yes
[16:43] <Laurenceb> and you might need to tie reset to vcc if its anything like AVR
[16:43] <akawaka> depends on how the config flags are set
[16:44] <Laurenceb> I only ever use AVR
[16:44] <akawaka> i hadn't noticed:)
[16:44] <Laurenceb> AVR > PIC
[16:44] <akawaka> been meaning to try avr, all their good stuff seems to be smd though
[16:44] <Laurenceb> smd isnt too bad, boards are
[16:45] <Laurenceb> but you can get smd mega168 and mega32
[16:45] <akawaka> you haven't seen my soldering
[16:45] <Laurenceb> they are some of the nicest
[16:45] <Laurenceb> lol
[16:45] <Laurenceb> s/smd/DIP
[16:45] <akawaka> i ain't no college edumacated solderist
[16:46] <akawaka> do the avrs have a similiar serial programming interface to the pics?
[16:46] <Laurenceb> they have spi programming
[16:48] <Laurenceb> lots of cheap programmers, you can just use a parallel port if your a cheapskate
[16:49] <jcoxon> right i've grounded the xtal with the caps
[16:49] <akawaka> i'll make a programmer with a pic
[16:49] <akawaka> muhahaha!
[16:49] <Laurenceb> might be tricky
[16:50] <Laurenceb> the programming protocol is fairly complex IIRC
[16:50] <Laurenceb> if you use an AVR to make the programmer theres code out there to do it
[16:50] <Laurenceb> but how do you program your first avr?  :P
[16:51] <jcoxon> chicken or the egg
[16:51] <edmoore> you use the parallel port
[16:51] <edmoore> it's trivial
[16:51] <edmoore> about 3 components
[16:51] <Laurenceb> exactly
[16:51] <jcoxon> sooooooo
[16:51] <Laurenceb> what I was leading up to :D
[16:52] <jcoxon> do i tie the reset to +ve or gnd?
[16:52] <Laurenceb> is it a reset or a /reset  ?
[16:53] <jcoxon> ummmm
[16:54] <akawaka> /reset
[16:54] <akawaka> do you have the source code?

[16:55] <fnoble> jcoxon: what yo makin'?
[16:55] <jcoxon> a rocketboy radio modem
[16:55] <jcoxon> i have the bits
[16:55] <fnoble> ooh nice
[16:55] <jcoxon> and a bit of a circuit
[16:55] <jcoxon> but am a little confused
[16:55] <fnoble> on perfboard?
[16:55] <jcoxon> my breadboard right now
[16:56] <fnoble> cool, reset is pulled high btw
[16:56] <jcoxon> is there a way of seeing if the pic is working?
[16:56] <jcoxon> its preprogrammed by rocketboy
[16:57] <jcoxon> no pin that goes high on start up?
[16:57] <fnoble> erm, depends on the code thats in it
[16:57] <Laurenceb> check the led pin
[16:57] <fnoble> if its programmed to flash an LED or something then
[16:57] <fnoble> yeah, just connect that up first
[16:57] <Laurenceb> theres an led on one of the pins in his design
[16:57] <jcoxon> yeah
[16:57] <jcoxon> but i'm not sure what pin thats on
[16:58] <jcoxon> its not in the diagram he gave me
[16:58] <Laurenceb> check the radio enable line
[16:58] <fnoble> should only need power, crystal, and reset pulled high to work
[16:58] <fnoble> and decoupling caps on the supply
[16:59] <jcoxon> so i've got 3.3v, a crytal with caps gnd the pins, reset is high
[16:59] <jcoxon> need to stick decoupling caps
[16:59] <jcoxon> between +ve off my reg and VDD?
[17:01] <fnoble> yeah
[17:02] <fnoble> as close as possible to the power pins on the PIC
[17:04] <edmoore> pics have vdd and vss next to each other
[17:04] <edmoore> so you can just stick the decoupling caps across
[17:04] <edmoore> most micros do for that very reason, infact
[17:04] <Laurenceb> anyone got any idea whats going on here: RCPT TO <email_address> failed: Requested action not taken: mailbox unavailable
[17:05] <Laurenceb> my email client keeps giving me that error when I send recieve
[17:06] <jcoxon> PICs are quite tough, if i screw up it should survive?
[17:07] <fnoble> yeah, should be ok
[17:07] <jcoxon> good good :-)
[17:07] <jcoxon> right i've taken the radio off
[17:07] <jcoxon> and stuck and led on the radio enable line
[17:09] <Laurenceb> it should light for a couple of seconds
[17:12] <jcoxon> hmmm nope
[17:12] <Laurenceb> power off
[17:12] <fnoble> the LED is the right way round?
[17:12] <jcoxon> :-p
[17:13] <fnoble> Laurenceb: do you have a good way of remembering the transformation of speeds formulae in special relativity?
[17:13] <fnoble> sorry, OT I know
[17:13] <Laurenceb> well... I just remeber it :P
[17:14] <fnoble> i can never remember which is the speed goes where
[17:14] <Laurenceb> if you understand whats going on, then its obvious, seriously, there not much to in physics you have to remember like that
[17:15] <Laurenceb> maybe some of the qm thats really weird
[17:15] <jcoxon> crap i hope i haven't broken it
[17:15] <jcoxon> no magic smoke has escaped :-p
[17:15] <Laurenceb> check all the wiring carefully
[17:15] <Laurenceb> then go for a walk
[17:15] <Laurenceb> then check it again
[17:15] <Laurenceb> :D
[17:15] <fnoble> check there is power on the pins

[17:18] <jcoxon> there is power on the pins
[17:18] <Laurenceb> might be the crystal
[17:18] <Laurenceb> an avr will work on breadboard with 22pf, but the tracks are 15pf
[17:19] <Laurenceb> so you have 37pf or so in effect
[17:24] <Laurenceb> how do I investigate processor use on linux?
