00:09 shimi 05d9
00:43 shimi rue i got an easy plane
00:43 shimi r u in the mood to see?
00:46 rue_mohr get it and we'll see
00:47 shimi i want just to link a video camera which records to mem card or somthing similar to this robot http://www.amazon.com/XPV-Mini-Blue-27-MHz/dp/B000RYQJEA/ref=sr_1_5?s=toys-and-games&ie=UTF8&qid=1319865901&sr=1-5
00:51 shimi do u know of more pro flying robot for buying?
00:51 shimi small sized one :)
01:49 rue_mohr no robot ones
01:49 rue_mohr how about just rc copters you ca mod for computer control
07:16 Tobias| Out of curiosity, what fraction of jobs in the robotics(/robotics engineering) field would you guys think pertained to intelligent robotics, as opposed to manufacturing and the like?
10:06 shimi rue...u here?
10:31 walkingfish Hi.. does anyone now on line have experience with socket can drivers
11:21 rue_mohr shimi,
11:21 rue_mohr walkingfish, socket can?
11:21 rue_mohr socket based canbus?
12:26 coppermine i have an old laptop i want to use as a the linux brains for my robot, what kind of DC motor specs would I need to haul 20-30lbs of payload? (ah battery + 7lbs laptop + other stuff) ?
12:38 Tom_itx that's alot of beer
14:02 coppermine can someone show me a 12vdc motor capable of 20-30lbs payload?
14:02 coppermine from http://www.robotcombat.com/products/motors_main.html
14:03 Tom_itx somewhat depends on gearing as well
14:03 Tom_itx i can get a pager motor to move 20-30 lbs
14:03 Tom_itx it may take a while to notice the movement though
14:04 Tom_itx look in the geared motor section
14:05 coppermine alright
14:05 coppermine i have calculators and stuff
14:05 Tom_itx or one of the other 'geared' sections
14:05 coppermine but they dont say "up to 20-30lbs"
14:05 Tom_itx some give an approx weight
14:06 coppermine it would be a 2 wheel drive system
14:06 coppermine i would put dummy wheels inthe back
14:06 coppermine and what does 300:1 ratio mean
14:06 coppermine i dont understand ratios in these motors
14:06 Tom_itx or get some cheap 12v screwdrivers and use them
14:18 coppermine http://www.ebay.com/itm/Copal-Gearhead-Motor-110-RPM-12-VDC-High-Torque-4-in-lb-LC37G-183VU-/270835488956?pt=LH_DefaultDomain_0&hash=item3f0f0d98bc
14:19 coppermine this looks like it would support 20-30lbs.. 2 of these motors, what do you think
15:00 pepsi_ sup
15:16 rue_mohr pneumatic muscle servo
16:15 rue_mohr ok I worked out a bit more of how to code this
16:16 rue_mohr if (force > 0) {
16:16 rue_mohr //!!!???!!! adjust pulse forward
16:16 rue_mohr } else if (force < 0) {
16:16 rue_mohr //!!!???!!! adjust pulse backward
16:16 rue_mohr }
16:16 rue_mohr hmmm
16:18 rue_mohr ok there are two output bits needed here, one for load, the other for unload
16:19 rue_mohr now, you never load and unload a muscle at the same time, so i wonder if its better to use a dir/pwm type signal instead of a sideA/sideB type
16:19 rue_mohr then again, I dont want to incurr more hardware here
16:20 rue_mohr than again, this is just a concept test, I'm not using an avr for this ultimitly...
16:23 rue_mohr I wonder if back to back switch-ons are a problem
16:24 rue_mohr so maybe I can do this like plain old pwm
16:24 rue_mohr but I need to make sure the output stays complimentrary
16:24 rue_mohr so I could just use one signed int
16:24 rue_mohr k
16:31 rue_mohr hmm, 255 counts is more than enough
16:32 coppermine can a pair of these motors carry 20-30lbs of payload?
16:32 coppermine http://www.trossenrobotics.com/store/p/5142-FIRST-CIM-Motor.aspx
16:32 rue_mohr with enough gearing they can take a 5000lb payload
16:32 rue_mohr use gearmotors
16:32 rue_mohr coppermine, what do you want the max speed of your robot to be?
16:33 coppermine rue_mohr: doesnt matter at this point.. not too slow but not very fast either
16:33 coppermine its my first build
16:33 rue_mohr aaah
16:33 coppermine but i do need 20-30lbs of payload
16:33 coppermine i chose my motor controllers
16:33 rue_mohr ok, get a gearmotor that can do...
16:33 coppermine http://www.pololu.com/catalog/product/1378
16:33 coppermine a pair of those
16:33 coppermine so i cant exceed the amps
16:33 coppermine 12A continous output
16:33 rue_mohr 200rpm max
16:33 coppermine at 12v
16:34 rue_mohr get a gearmotor that can do 200rpm
16:34 coppermine thats not enough for 20-30lbs
16:34 coppermine thats for small robots
16:34 rue_mohr rpm has NOTHING to do with load
16:34 rue_mohr this is for wheels?
16:34 coppermine well i checked robotcombat or something
16:34 coppermine and they all say up to 13lbs
16:34 coppermine for 200rpm
16:34 coppermine 20$ range
16:34 coppermine yes
16:34 coppermine 4 wheels
16:34 rue_mohr GEARmotor?
16:35 coppermine 2 front
16:35 coppermine 2 dummies back
16:35 coppermine yes gear brushed
16:35 rue_mohr 200rpm max
16:35 coppermine i tried a few caluclators
16:35 coppermine and they dont match up
16:35 coppermine for the 200rpm motors
16:35 rue_mohr 30lbs, you want a specific amount of torque
16:35 coppermine how much
16:35 coppermine gedit
16:35 coppermine oops
16:35 rue_mohr what slope do you want it to drive up?
16:36 coppermine ok im writting the specs
16:36 coppermine so i need 200rpms
16:36 coppermine gear motoro
16:36 coppermine brushed
16:36 coppermine anything else?
16:36 rue_mohr what slope do you want it to drive up?
16:36 coppermine how much torque
16:36 rue_mohr what slope do you want it to drive up?
16:36 coppermine 10% is fine
16:36 coppermine maybe up to 20
16:36 rue_mohr how much does the robot weigh, the 25lbs?
16:36 coppermine yes i want about 25lbs total robot weight
16:36 coppermine including battery
16:36 coppermine and cpu,etc
16:36 coppermine cameras
16:37 rue_mohr ok so its only pulling about 7lbs force on the wheels
16:37 rue_mohr about how big wheels are you gonna use?
16:37 coppermine if its 4WD you mean?
16:37 rue_mohr 4"
16:37 rue_mohr ?
16:37 coppermine sure
16:37 coppermine 4 inch diameter
16:37 rue_mohr so 7lbs@4" is 28inch-lbs
16:37 coppermine thats 4WD
16:37 coppermine with 4 motor controllers
16:37 rue_mohr do you need that in oz-in?
16:37 coppermine no
16:38 coppermine just show me a product that will work lol
16:38 rue_mohr this is for 1wd, it'll be twice as strong as it needs to be
16:38 coppermine so how much torque do i need for 200rpms for 28lbs
16:39 rue_mohr 28 inch-lbs
16:39 coppermine oh u said thwta already
16:39 coppermine what is it in oz-in too then
16:39 coppermine some caluclators dont have that
16:39 rue_mohr I aksed if you nwated it converted too
16:39 coppermine yes please
16:39 rue_mohr 448 inch-oz
16:40 coppermine ok let me start searching
16:40 rue_mohr http://www.baldor.com/pdf/literature/BR1502_0305.pdf
16:41 coppermine see you are wrong
16:41 coppermine it came up with these motors
16:41 coppermine http://www.robotmarketplace.com/products/0-BPK51.html
16:41 coppermine and it says up to 12lbs
16:41 coppermine or is that per motor?
16:41 coppermine or total
16:42 rue_mohr you dont understand what the 12lbs is in reference to
16:42 coppermine no
16:42 coppermine im learning
16:42 rue_mohr the 12V one looks fine, 396oz-in 190rpm
16:42 coppermine i can compile a gentoo kernel but im learning about dc motors :)
16:42 coppermine so the 12lbs is per wheel?
16:43 coppermine 5-12lbs/wheel?
16:43 rue_mohr no thats 25lbs per wheel
16:43 rue_mohr I use a 200% margin
16:43 coppermine These PK-Series motors are great for directly-driving wheels on small robots (5-12 pounds), and are available with two different gear ratios. Choose from either a high speed 27:1 or a high torque 51:1
16:43 coppermine confusing
16:43 rue_mohr yes, the 12lb limit will be the bearing limit, not hte motor limit
16:43 coppermine so with 2 of these
16:43 coppermine how much weight can i pull
16:44 rue_mohr the max is 14lbs
16:44 rue_mohr 7lbs is 25% grade
16:44 coppermine and 4 motors would mean 28lbs?
16:44 rue_mohr you can drag with 14lbs force
16:44 rue_mohr yes
16:44 coppermine ok so ill buy 4
16:44 rue_mohr if their not fighting each other
16:45 coppermine thats 200$ of dc motors
16:45 coppermine i would have to send forward instructions at the same time
16:45 coppermine on all 4
16:45 coppermine to advance
16:45 rue_mohr want to use a blender motor and make a gearbox?
16:45 coppermine start shell scripts in parallel
16:45 coppermine no
16:45 coppermine fun fun
16:45 rue_mohr do you understand they are saying you cannot push a wheel on those motors and stress the bearings with mroe than 12lbs force?
16:46 coppermine no
16:46 rue_mohr the bearing in those motors are the weak points
16:46 coppermine oh ok
16:46 coppermine i prefer 2 motors
16:46 coppermine with higher power
16:46 coppermine would cost less
16:46 coppermine and easier to manage
16:46 rue_mohr if you support the wheel and have a chain drive it, you can put as much weight as you want on the robot if you stay on a flat floor
16:46 coppermine with a caster wheel
16:47 rue_mohr mow much do two cordless drills cost?
16:47 coppermine 120$
16:47 coppermine with the battery
16:47 coppermine dewalt
16:47 coppermine no
16:47 coppermine thats 1
16:47 coppermine so 240$
16:47 rue_mohr hmm
16:47 rue_mohr how about cheap ones?
16:48 coppermine roybi?
16:48 rue_mohr no name brand
16:48 coppermine mayhbe half that
16:48 coppermine it wont becompatible
16:48 coppermine the holes wont match up
16:48 coppermine too much hackign for a beginner
16:48 rue_mohr what holes?
16:48 coppermine i need the shaft to match
16:48 coppermine with the wheel hub
16:48 coppermine etc
16:48 rue_mohr I can show you how o attach a wheel to a drill with les than $3 in parts
16:48 coppermine http://www.pololu.com/catalog/product/1084
16:49 coppermine these holes
16:49 rue_mohr seeing as its got a chuck
16:49 rue_mohr do you HAVE to use those brackets?
16:49 coppermine i can use what i want
16:49 coppermine its just easier
16:49 rue_mohr have you never walked up and down the isles of a hardware store?
16:50 coppermine have you?
16:50 rue_mohr if you want easy and fast, dont complain about the price
16:50 rue_mohr if you want low price and fast, dont complain about it not being easy
16:50 coppermine im not complaining
16:50 rue_mohr if you want low price and easy, dont complain about it taking a while
16:50 coppermine i want to find 2 motors 12vdc that can pull 25lbs of weight
16:50 coppermine is that too much to ask?
16:51 rue_mohr but thats it, its not PULLING the weight
16:51 coppermine its a payload
16:51 coppermine total weight
16:51 rue_mohr a robot that weighs 100000lbs will roll across a flat floor with even 1lb of force
16:51 coppermine im not good with physics/math
16:51 rue_mohr thats what were for
16:52 rue_mohr if you have a 100lb robot, going straight up, it takes 100lbs of force
16:52 rue_mohr if that robot is going up a 45 degree angle, your at 50lbs force
16:53 rue_mohr 22.5 degrees is 25lbs
16:53 coppermine shouldnt it force more with angles?
16:53 rue_mohr so flat is, in theroy, 0lbs force
16:53 coppermine ok got it
16:53 coppermine flat 180degrees
16:53 coppermine 0 lbs force
16:54 rue_mohr so tell us a little about the robot you want to make
16:54 coppermine thats all you need to know
16:54 coppermine it needs to haul 25lbs max
16:54 rue_mohr oh I see
16:54 coppermine i would be violating my patent if i told you
16:55 rue_mohr so, do you understand how to convert force to torque?
16:56 e_mohr goes back to his pwm
17:23 pepsi_ arent you disclosing information when you file for a patent anyhow?
17:23 pepsi_ wtf
17:23 Tom_itx yeah don't you know that's where all the chinese hang out?
19:09 Tom_itx what's up zhanx?
19:41 Tom_itx rue_mohr
19:41 Tom_itx wake up
19:41 Tom_itx zhanx ATTENTION!
19:57 Tom_itx well crap
19:57 m_itx takes a
20:14 zhanx Tom_itx i am back
20:14 zhanx i had to do a color guard detail
20:14 Tom_itx oh
20:14 Tom_itx well i was sittin here tryin to figure out what to do next
20:14 zhanx so color guard detail tonight was CRAZY
20:15 zhanx they had a full film crew there
20:15 Tom_itx fun
20:15 zhanx need to google the tv show we will be on
20:16 zhanx something with some dude from american idol
20:16 zhanx we had no clue on it
20:17 zhanx this guy was there http://en.wikipedia.org/wiki/Matthew_Rogers
20:17 zhanx Coming Home that is the name of it
20:18 zhanx i got to setup the family
20:18 zhanx i was asked to place a bag next to them and ask them to watch it for me since they were where the color guard was stopping etc.
20:19 zhanx it was the dad's bag and none of the family knew he was home etc.
20:20 Tom_itx cool
20:21 zhanx i left without getting the bag etc.. not sure what happened next as we got kicked etc
20:22 zhanx need to cook food (venison and rice) then start codeing
20:22 Tom_itx wanna help set up my tool chain?
20:22 zhanx aka that script for you... sure
20:22 zhanx what tool chain you using?
20:22 Tom_itx if i don't doo something soon i'm gonna fall asleep though
20:22 Tom_itx the one you suggested
20:22 zhanx ok
20:23 zhanx i setup up my apps/ tool chains in a different way.. what is your prefered method. i.e local or gobal
20:23 zhanx and os
20:23 Tom_itx ubuntu
20:23 zhanx verison
20:23 Tom_itx and i have no clue
20:23 Tom_itx 10.04
20:23 zhanx ok local for now and same verison
20:24 Tom_itx i copied the compiler to a dir already
20:24 zhanx ok here is the first couple things you need in a command
20:24 Tom_itx /tom/arm-cs-tools
20:24 Tom_itx and i have their makefile
20:24 Tom_itx but i get errors with it
20:24 zhanx sudo apt-get install patch libusb-dev automake libtool texinfo
20:25 zhanx textlive
20:25 Tom_itx lemme join on ubuntu and you can give it to me again
20:25 zhanx ok
20:26 zhanx will send it all on one line
20:26 Tom_itx mkay
20:26 atom1 when you're ready
20:26 zhanx sudo apt-get install patch libusb-dev automake libtool texinfo textlive gcc-arm-linux-guneabi
20:26 zhanx wait
20:26 zhanx you need to do this first
20:27 zhanx sudo add-apt-repository ppa:linaro-maintainers/toolchain
20:27 zhanx then that command line
20:27 Tom_itx https://github.com/jsnyder/arm-eabi-toolchain
20:27 Tom_itx i did some of that already
20:27 zhanx mine works....
20:28 Tom_itx ok i did the first one
20:28 zhanx let me know when the apt's are installed
20:29 atom1 Couldn't find package textlive
20:29 zhanx texlive sorry
20:29 rue_mohr hmm if I'm tired should I got to sleep
20:29 zhanx naa
20:29 zhanx_laptop or maybe you should
20:29 zhanx_laptop brb
20:30 atom1 Couldn't find package gcc-arm-linux-guneabi
20:30 atom1 rue, he assumes i'm linux savvy :)
20:31 zhanx sudo add-apt-repository ppa:linaro-maintainers/toolchain
20:31 zhanx you add that?
20:32 Tom_itx did that already per above
20:32 Tom_itx first
20:32 zhanx hmmm

20:33 zhanx you add the universe to your package list
20:33 zhanx under sources in the gui
20:35 atom1 where?
20:35 atom1 i've got it open
20:35 zhanx brb sorry
20:37 zhanx k
20:37 atom1 i'm in 'software sources window'
20:37 atom1 now what?
20:39 zhanx see the community-mainted open source software (universe)
20:39 zhanx is that checked
20:39 Tom_itx yes
20:39 zhanx weird
20:40 zhanx_laptop copied right off my command line
20:40 zhanx_laptop sudo apt-get install gcc-arm-linux-gnueabi
20:40 atom1 just a sec
20:40 zhanx th gun vs gnu
20:41 rue_mohr hmm I can make this not quite pwm, but a one-shot
20:41 atom1 better
20:41 Tom_itx but i already installed it once
20:41 rue_mohr I just need to make sure the new calcs aren't triggered till the pulse is finished
20:41 Tom_itx zhanx
20:41 rue_mohr but that might cause probelms for the code doing multiple axies at once
20:41 Tom_itx i downloaded their tar file and installed it
20:42 rue_mohr but this is just test code, I'm not running 20 muscles off this
20:42 Tom_itx is this a duplicate?
20:42 rue_mohr so I could just use a countdown
20:42 zhanx its a proper install of it
20:42 Tom_itx so i can delete the other files?
20:42 zhanx yep
20:42 zhanx well if you want local no
20:42 atom1 gone
20:42 zhanx i am doing gobal for you so its easier for you
20:43 atom1 no matter
20:43 atom1 but carry on
20:43 rue_mohr I dont need a flag, if its just a countdown then I can know its finished if the counter is zero
20:43 rue_mohr this brings up a number of interesting problems
20:43 zhanx now we need to setup the way your board sees the computer and viceversa
20:43 atom1 it won't screw up other compilers options will it?
20:44 zhanx nope its for arm is all
20:44 Tom_itx where did you copy the sample files?
20:44 zhanx_laptop to my workbook folder
20:44 zhanx_laptop git clone https://github.com/texane/stlink stlink.git
20:45 zhanx_laptop cd stlink.git
20:45 zhanx_laptop make -C build && sudo ./build/st-util [/dev/sgX]
20:45 Tom_itx want me to run that?
20:45 Tom_itx the git line?
20:45 zhanx_laptop yes
20:45 zhanx_laptop if it errors do sudo apt-get install git
20:46 Tom_itx yeah i knew i didn't have that
20:47 atom1 Reading package lists... Done
20:47 atom1 Building dependency tree
20:47 atom1 Reading state information... Done
20:47 atom1 Package git is not available, but is referred to by another package.
20:47 atom1 This may mean that the package is missing, has been obsoleted, or
20:47 atom1 is only available from another source
20:47 atom1 E: Package git has no installation candidate
20:47 rue_mohr what file are you looking for
20:48 atom1 git
20:48 rue_mohr haha you cant find git?
20:48 atom1 i'm sure it's in the package manager
20:48 atom1 but i was following directions
20:50 zhanx sorry
20:50 zhanx sudo apt-get install git-core
20:50 zhanx ( i forget your new at linux)
20:51 atom1 well i found it in the package manager
20:51 atom1 do i want the gui too?
20:51 rue_mohr apt-cache search git
20:51 atom1 shhh
20:52 zhanx your choice on the gui i never use it
20:52 rue_mohr wrong counts, its ssh
20:52 zhanx ssh is your freind
20:52 rue_mohr s^2h
20:52 rue_mohr sulfor hydroxide?
20:52 rue_mohr atom count is all wrong
20:53 atom1 it's like a windows install
20:53 atom1 grabbing all sorts of extras along the way
20:53 rue_mohr its a dependency tree
20:54 atom1 ok now what?
20:54 rue_mohr unlike windows pograms aren't 100% atomic
20:54 zhanx ok your tool chain is setup
20:54 zhanx :D
20:54 zhanx now you need to be able to program the board
20:54 zhanx which you need stlink for off google code.
20:55 Tom_itx hold on i'm getting the files now
20:55 zhanx k
20:55 atom1 git clone https://github.com/texane/stlink stlink.git
20:55 atom1 <zhanx_laptop> cd stlink.git
20:55 atom1 did that
20:55 zhanx_laptop make -C build && sudo ./build/st-util [/dev/sgX]
20:56 zhanx_laptop make
20:56 zhanx_laptop sudo ./build/st-util [/dev/sgX]

20:56 atom1 make: *** build: No such file or directory. Stop.
20:57 zhanx go to the next one

20:58 zhanx you did the sudo apt-install libusbdev?
20:58 atom1 beats me
20:58 rue_mohr you guys are working on the arm stuff right?
20:58 zhanx yep
20:58 atom1 not found
20:58 atom1 apt-install command not found
20:59 atom1 ;/
20:59 zhanx you did the sudo apt-install libusb-dev
20:59 rue_mohr apt-get install
20:59 zhanx you did the sudo apt-get install libusb-dev
20:59 atom1 i figgered it rue
20:59 zhanx better sorry
20:59 zhanx working on ten things at once
20:59 atom1 lib installed
21:00 atom1 limit it to one then
21:00 zhanx hmmm
21:01 atom1 you're losing me
21:02 zhanx looking up my guide
21:02 zhanx_laptop https://sites.google.com/a/stf12.net/developer-sw-fw/eclipse-demo
21:02 zhanx that is what i used to setup mine
21:03 zhanx and my laptop times out
21:03 Tom_itx says depreciated
21:03 Tom_itx see new demo
21:04 zhanx click it
21:05 Tom_itx did
21:05 zhanx http://www.stf12.org/developers/ODeV.html
21:05 zhanx that is the link sorry
21:05 zhanx my laptop timed out too fast
21:06 atom1 ok so where are we at now?
21:06 zhanx start at the beginning it will skip the duplicates etc
21:06 zhanx i needs to finish dinner for a minute
21:07 coppermine how do I connect http://www.robotcombat.com/products/BPDWC10.html to a motor's 6mm shaft?
21:08 Tom_itx you gonna drive it direct?
21:08 coppermine direct from the shaft yes
21:08 coppermine or I can put a hub
21:09 coppermine either
21:09 Tom_itx you gonna have to make a 6mm hub
21:09 Tom_itx doesn't look like that wheel has a hub
21:09 coppermine i can buy a 6mm hub
21:09 coppermine but there's nothing to screw it on
21:09 coppermine just a 1 3/16" bore
21:09 Tom_itx then you need a hub for it
21:10 coppermine is there a nice 4 inch diamater tire that connects to a 6mm motor shaft?
21:10 coppermine so i dont have to break my head
21:11 Tom_itx http://www.robotmarketplace.com/products/0-RW2.html
21:11 Tom_itx 3mm
21:12 coppermine and you can drill it it says
21:12 coppermine so i can make it 6mm
21:13 Tom_itx if you can center it accurately and there is enough metal there to remove, yes
21:13 coppermine probably cant then
21:13 coppermine ill keep looking for a 6mm tire
21:13 Tom_itx i'd email them and ask
21:13 coppermine anyways doesn say its 4 inches
21:14 coppermine i found a smaller tire.. 3 inch or so, but i realized that my motors will force more
21:14 coppermine if you go bigger tires, you get more torque
21:14 Tom_itx less
21:14 coppermine so its ok to buy a smaller tire?
21:14 Tom_itx more speed
21:14 coppermine i was gonna go with some sumo
21:15 coppermine http://www.robotcombat.com/products/BPDWC10.html
21:15 coppermine 2.88inches
21:15 coppermine but it changes the calculations
21:15 Tom_itx pretty small
21:15 coppermine wondering if it iwll be fine
21:15 coppermine i dont think so
21:15 Tom_itx smaller than the motor diameter?
21:15 coppermine they are 6mm
21:15 coppermine same as motor
21:15 Tom_itx then the motor will drag the ground
21:16 coppermine what does that mean
21:16 Tom_itx it won't work
21:16 coppermine ok
21:16 coppermine a 6mm shaft first in a 6mm bore
21:16 coppermine why wouldnt it work
21:16 coppermine first=fits
21:17 rue_mohr hmm how do I TEST this code...
21:18 Tom_itx motor diameter = 2.88", wheel diameter =3" means you have .22" clearance for the motor before it will drag the floor
21:18 coppermine no
21:18 coppermine i didnt say thata
21:18 Tom_itx is what you said
21:18 coppermine the wheel diameter is 2.88" as the link I gave you shows
21:19 coppermine I didnt talk about any motor diameter
21:19 Tom_itx so what is it then?
21:19 coppermine i'd have to check
21:19 Tom_itx you'd better check.
21:19 coppermine it doesnt matter
21:19 Tom_itx mkay
21:19 coppermine cause im screwing it to the top of the base
21:19 coppermine the platform
21:19 coppermine with a bracket
21:19 m_itx goes back to arm
21:21 Tom_itx zhanx, i need to install eclipse too?
21:21 zhanx only if you want it
21:21 zhanx i use it for the gui etc
21:21 Tom_itx i don't know what i want at this point
21:21 zhanx if you choose to use it, i would
21:22 zhanx i will send you my master template when its done for easy startup etc
21:22 Tom_itx doesn't mean it'll work for me :)
21:22 zhanx it will
21:23 zhanx i am making a template for eclipse etc
21:23 atom1 but i'm still sitting here with no arm dev env too
21:23 zhanx your arm dev env is done
21:23 Tom_itx then why do i need that page?
21:23 zhanx to finsih you board commo
21:23 zhanx stlink is the key
21:24 atom1 and where is that?
21:24 zhanx the arm dev env is easy and towards the end
21:24 atom1 i got the stlink.git
21:25 zhanx make
21:25 zhanx sudo makeinstall
21:25 rue_mohr sudo make install
21:25 e_mohr throws a bucket of spaces
21:25 zhanx opps
21:25 atom1 no rule to make install
21:25 zhanx rue is right
21:26 rue_mohr tom remembered the space
21:26 zhanx i have people over
21:26 rue_mohr the makefile dosn't have an install
21:26 rue_mohr wonder why not
21:26 rue_mohr what did tom make
21:26 rue_mohr ?
21:26 zhanx i dont type well tonight
21:26 zhanx stlink a port for linux and arm programming
21:27 rue_mohr ok
21:27 atom1 what about make all?
21:27 rue_mohr odd it'd have no make install
21:27 rue_mohr maybe there is a seperate install script
21:27 zhanx it is
21:27 atom1 well shite
21:27 rue_mohr Tom_itx, try the command less INSTALL
21:27 rue_mohr see what is says
21:27 zhanx tom should have done make first
21:27 coppermine less? haha
21:27 coppermine use vi
21:27 zhanx then a sudo make install
21:28 atom1 no such file or dir
21:28 rue_mohr hmm
21:28 rue_mohr this is quite odd
21:28 zhanx i need remote
21:28 zhanx can i ssh your box?
21:28 rue_mohr is there any file called isntall on there?
21:28 atom1 u 2 are gonna get me all messed up
21:28 zhanx if i can ssh to your box i can setup the whole thing
21:28 rue_mohr I'm about to go to bed
21:28 coppermine don't give him access
21:28 atom1 but i want to know how to
21:28 coppermine or set up a chroot
21:29 atom1 do it later
21:29 zhanx k
21:29 zhanx not on my linux box
21:29 atom1 i'm not quite sure of the end result here anyway
21:29 rue_mohr Tom_itx, want to guide me thru and I'll see if I can tell where the screwup is?
21:29 rue_mohr you have notes, right?
21:29 Tom_itx notes/
21:29 Tom_itx ?
21:30 Tom_itx no not yet
21:30 zhanx it to setup /dev/st000etc to be able to be able to program the board
21:30 zhanx your dev env is stetup
21:30 rue_mohr atom1, to have a compiled install of an arm compiler and toolchain
21:30 atom1 i only need one though
21:30 atom1 not several
21:31 zhanx its setup tom the issue is the stlink crap unless you want to jtag program the board
21:31 atom1 nope
21:31 atom1 i want it set up
21:31 atom1 i have th stlinks stuff
21:31 zhanx i would do as i am doing
21:31 atom1 but apparently it's not set up
21:31 atom1 i can dump it and start over
21:31 zhanx i use my linux box to make the program and my windows box to program it
21:32 atom1 why?
21:32 zhanx easier
21:32 om1 mutters some obsceni
21:32 zhanx and it complies smaller under linux for some odd reason
21:32 zhanx like 30% in some cases
21:33 zhanx heck the default programs are compling 15k small under linux vs windows
21:33 atom1 do they work the same?
21:33 zhanx yep
21:33 zhanx and debug the same
21:33 zhanx its odd to say the least
21:34 atom1 what's wrong with linux for uploading?
21:34 zhanx its a pita
21:34 atom1 what do you use in windows?
21:35 zhanx the stlink util
21:36 atom1 from them?
21:36 zhanx my blink the led was 4 bytes small under linux than windows ... odd and yes
21:36 atom1 so what's left to do for linux then?
21:37 zhanx stlink stuff
21:38 atom1 do i want passthru or raw?
21:38 atom1 2 different transport layers are used:
21:38 atom1 . STLINKv1 uses SCSI passthru commands over USB,
21:38 atom1 . STLINKv2 uses raw USB commands.
21:40 zhanx v2
22:08 Tom_itx zhanx do i need libusb-1.0-0 or libusb-1.0-0 dev?
22:08 Tom_itx or both
22:09 zhanx dev
22:09 zhanx bpth wont hurt
22:09 atom1 libusb-1.0/libusb.h: No such file or directory
22:09 Tom_itx k
22:09 Tom_itx that's probably why
22:09 Tom_itx no dev
22:09 zhanx dev you need to make etc
22:09 zhanx depends etc
22:10 Tom_itx ok
22:10 Tom_itx i did
22:11 atom1 make CONFIG_USE_LIBSG=0
22:11 atom1 and that worked
22:11 zhanx cool
22:11 atom1 per pdf i found in the files
22:11 atom1 what next?
22:11 zhanx so the make is done?
22:11 Tom_itx that one is
22:11 zhanx sudo makeinstall
22:12 zhanx or sudo make install
22:12 anx uses rue's sp
22:12 Tom_itx goddammit
22:12 Tom_itx no rule .....
22:12 zhanx link to pdf
22:13 Tom_itx i'll put it on my site hang on
22:13 zhanx k
22:16 atom1 http://tom-itx.dyndns.org:81/~webpage/rue/tutorial.pdf
22:16 Tom_itx under 3) installing stlink
22:17 Tom_itx but if you're using eclipse i want to set that up
22:18 zhanx eclipse is the first link
22:18 Tom_itx where?
22:19 zhanx from now on since you used ~/stlink.git all uploads will need to be from there unless you etc your bash rc
22:19 Tom_itx whatever is easiest in the end
22:20 zhanx this http://www.stf12.org/developers/odev-linux.html
22:20 zhanx that is easy for me
22:21 Tom_itx i'd like mine set up like yours since i'm gonna need help
22:21 zhanx ok do that link then
22:22 zhanx and ONLY do that link ( it will fubar if you add more like avr support etc)
22:22 Tom_itx ok but i'm running 10.04 ubuntu too
22:22 zhanx i have eclipse installs for arm / avr and java now due too the issues for it
22:22 Tom_itx it refers to 11.04
22:22 zhanx I am also
22:22 zhanx so what
22:22 Tom_itx you never know so what
22:22 zhanx true
22:23 zhanx it worked for me
22:23 Tom_itx just mentioned it
22:23 Tom_itx so forget the pdf for now then and follow that from here
22:23 Tom_itx i wanna fix the ~stlink.git thing too
22:23 zhanx yep and change the name to 10.04 vs 11.04
22:24 zhanx ok lets fix the ~/ thing first
22:24 zhanx in the terminal
22:24 zhanx cd ~
22:24 Tom_itx k
22:24 atom1 tom@atom1:~$
22:24 zhanx gedit .bashrc
22:25 atom1 ok
22:25 zhanx PATH=$PATH:$HOME/stlink.git <--- add that at the end
22:25 zhanx save and close
22:25 zhanx after logout it will be fixed
22:26 atom1 exit
22:26 atom1 term
22:26 zhanx then when you run a terminal command it will work fine
22:26 atom1 ok
22:26 zhanx now install eclipse per pdf
22:26 atom1 now what?
22:26 atom1 per pdf or html?
22:26 zhanx html sorry
22:27 zhanx watching halloween 2 and talking etc
22:27 anx is getting 4% of the brain p
22:27 m_itx gives zhanx some bubblegum
22:27 zhanx i also have 5 pads open with code on them
22:28 zhanx multi tasking FAIL
22:28 Tom_itx k, i'll keep goin on the html until i get stuck
22:28 zhanx k
22:28 Tom_itx which eclipse do i want?

22:29 Tom_itx Eclipse IDE for C/C++ Developers
22:29 zhanx yes
22:30 zhanx sh ./name of file in terminal
22:31 Tom_itx do i want developers or linux developers?
22:31 zhanx linux
22:32 zhanx getting your link
22:32 atom1 http://www.eclipse.org/downloads/packages/eclipse-ide-cc-linux-developers-includes-incubating-components/indigosr1
22:32 zhanx http://www.eclipse.org/downloads/download.php?file=/technology/epp/downloads/release/indigo/SR1/eclipse-cpp-indigo-SR1-incubation-linux-gtk.tar.gz&url=http://mirror.cs.rit.edu/mirrors/eclipse/technology/epp/downloads/release/indigo/SR1/eclipse-cpp-indigo-SR1-incubation-linux-gtk.tar.gz&mirror_id=483
22:38 Tom_itx guess i need java too
22:38 zhanx yep
22:38 Tom_itx where did you install eclipse?
22:38 zhanx eclipse is jave based
22:39 zhanx to ~/Applications
22:39 zhanx i have ~/Applications/EclipseArm
22:39 zhanx i have ~/Applications/EclipseAvr
22:39 zhanx i have ~/Applications/EclipseJave
22:40 Tom_itx what java do i need
22:40 Tom_itx i see several in package manager
22:40 zhanx the 6.0 one with the logo
22:41 zhanx i think its the first one
22:41 Tom_itx sun-java6-bin
22:42 zhanx yes
22:46 Tom_itx ok i think it's installed
22:46 zhanx ok run it
22:46 zhanx find the folder and double click the eclipse
22:47 Tom_itx it's open already
22:47 Tom_itx i think
22:47 zhanx if it fails to run right click and make exe on it
22:47 zhanx see a purple thingy?
22:47 atom1 yep
22:47 zhanx yep it is
22:47 zhanx ok follow the html on it from here
22:48 Tom_itx i'm not sure where i installed it :)
22:48 zhanx lol you extracted it to where?
22:49 Tom_itx it's in the downloads dir
22:49 zhanx ok its installed there
22:49 Tom_itx i should move it if that's where the install was
22:49 zhanx copy to your location etc
22:49 Tom_itx did you put it in the applications/eclipsearm dir?
22:49 zhanx yep
22:50 zhanx as the root of it
22:50 zhanx copy it to applications and rename it
22:55 Tom_itx where did you set your workspace?
22:56 zhanx default
22:58 Tom_itx the icon won't work
22:58 Tom_itx can't find shared lib
22:58 zhanx dont use the icon
22:58 Tom_itx pfft
22:58 zhanx look for the eclipse with a square rotated 90
22:58 zhanx err 45
22:59 Tom_itx i found it and copied it to the desktop
22:59 Tom_itx the rights look ok
22:59 zhanx dont
22:59 Tom_itx mmm
22:59 zhanx right click the desktop make a new launcher
22:59 zhanx and with that you can make it have the right icon
23:00 Tom_itx ok
23:12 e_bed notes the differences between being publically stoned and publically lo
23:13 Tom_itx is there?
23:13 rue_bed maybe we should say "we wont pubically stone you, but we will pubically log you"
23:13 rue_bed ok how long was my nap?
23:14 Tom_itx long enough?
23:14 rue_bed time to go code some air muscle
23:14 rue_bed did you find the install script for your toolchain?
23:15 Tom_itx i'm configuring eclipse now
23:15 rue_bed 'only comes around every million years
23:15 rue_bed ugh these cats need foood
23:15 Tom_itx i grabbed it while it was here
23:18 rue_bed hmm, I think I know how to proceede with the test code
23:19 rue_bed that'll get me a muscle going back and forth at a controlled speed
23:19 rue_bed then I just need to close the loop
23:27 Tom_itx ok rue
23:27 Tom_itx i may need some help
23:28 Tom_itx http://www.stf12.org/developers/ODeV.html#widget7
