Jun 08 03:32:30 <foreverska> Has anyone heard of a beaglebone being used to generate a carrier frequency for AM transmission before?
Jun 08 03:38:45 <pjustice> I've heard of it being used to generate RF, though the case in question wasn't specifically AM
Jun 08 03:39:45 <foreverska> Yea, AM would require some external hardware but if you can generate RF then you can generate a carrier freq.
Jun 08 03:56:03 <foreverska> Oh... this is nowhere near accurate enough.  If you could find one specific frequency you wanted maybe but it's not fast enough.
Jun 08 03:58:47 <pjustice> using the PRU?
Jun 08 03:59:31 <foreverska> Yea.  Well I mean if you think about it.  1 cycle on and off is 200Mhz.  2 cycle on and off is 100Mhz.  There's just not enough resolution there.
Jun 08 04:01:49 <foreverska> I mean if you push out to 500+ cycles you start being able to pick frequencies in the 160Meter ham band but you'd have to give the middle finger to band spacing.
Jun 08 04:03:05 <foreverska> *100+ cycle
Jun 08 04:08:55 <foreverska> Well... there's an idea...  Maybe using both with a mixer.  Pru 1 can pick a wide number and if that can get you within 3 or so MHz of intended band you might be able to not piss too many people off.
Jun 08 04:30:14 <ds2> foreverska: why are you thinking of doing it with the PRU?
Jun 08 04:30:50 <foreverska> What other option do we have?  It's the fastest with the best accuracy isn't it?
Jun 08 04:30:57 <ds2> no
Jun 08 04:31:08 <ds2> what mode you want to do?
Jun 08 04:31:15 <ds2> AM? FM? CW? SSB? Digital?
Jun 08 04:31:27 <foreverska> AM, CW, SSB
Jun 08 04:31:43 <ds2> AM and SSB is going to be hard
Jun 08 04:31:51 <ds2> actually no
Jun 08 04:31:54 <ds2> do it as DDS
Jun 08 04:32:05 <ds2> there is HW in there that might as well be a DDS
Jun 08 04:32:16 <ds2> but you need an ADC
Jun 08 04:32:21 <ds2> oops DAC
Jun 08 04:33:42 <foreverska> Well for AM the usual circuits can be applied when you get a frequency.  SSB you can just bandpass (I know that wastes but that's easiest).
Jun 08 04:39:40 <ds2> Oh you willing to externally modulate it?
Jun 08 04:39:50 <foreverska> Here's what I'm seeing:  Pru 1 coarse, Pru 2 medium, adjustable oscillator to fine tune freq.
Jun 08 04:40:16 <ds2> what about the video system?
Jun 08 04:40:23 <ds2> why not use that as a DDS?
Jun 08 04:40:40 <ds2> it clocks out data from RAM at a fixed speed
Jun 08 04:40:46 <ds2> put the clocks into a DAC
Jun 08 04:40:55 <ds2> low pass it
Jun 08 04:42:29 <foreverska> Video system?
Jun 08 04:42:57 <foreverska> Oh you mean LCD subsystem?
Jun 08 05:05:07 <ds2> yes

Jun 08 08:23:44 <tbr> ds2: you are going to invest this into beaglebones?
Jun 08 08:42:39 <steven_> is there a way to increase the period/frequency beyond 1 second for hardware PWM on the beaglebone black?
Jun 08 08:45:00 <foreverska> At that pace you could turn the bit on and off yourself
Jun 08 08:49:40 <steven_> I agree I can, just a bit more programming.  Had my fingers crossed for hardware solution.  I tried to increase through the "/sys/devices/ocp.3/pwm_test_P9_14.16/period", but it throws back an out of range.
Jun 08 08:52:17 <foreverska> That sounds pretty damning.  I really haven't played with PWN much sorry I'm not more help.
Jun 08 08:59:32 <tbr> steven_: look at the TRM if it's a HW limitation, if not it might just be a kernel thing
Jun 08 08:59:52 <tbr> so looking at the kernel code that controls the PWM would also be a good idea
Jun 08 09:05:22 <steven_> thanks tbr and forever
Jun 08 12:33:39 <milad> hi, i want to change the uboot logo when loading kernel, i mean the logo in upper corner and is it possible to change it's size? tnx
Jun 08 12:36:38 <milad> well
Jun 08 12:40:40 * tbr never noticed an uboot logo
Jun 08 12:41:06 <tbr> but just rebuild u-boot, I guess
Jun 08 12:42:18 <milad> i mean the pinguin. when the kernel is loading...
Jun 08 12:44:25 <tbr> that is NOT u-boot
Jun 08 12:44:28 <tbr> that's the kernel
Jun 08 12:45:06 <milad> so is there any chance to change it without compiling the kernel?
Jun 08 12:45:14 <tbr> hahahaha, no
Jun 08 12:46:05 <tbr> if you care for fancy graphics, turn off fbconsole and use psplash or such
Jun 08 12:47:00 <milad> how can i do that?
Jun 08 12:49:38 <tbr> I'd suggest to do it by reading documentation and applying what I learn
Jun 08 12:50:16 <tbr> console you can probably turn off on the u-boot command line and I bet that's well documented too
Jun 08 12:56:11 <milad> you mean i should change uEnv file? or sth else?
Jun 08 12:59:51 <tbr> yes
Jun 08 13:05:33 <milad> sorry tbr: but i don't have any idea of what to search for , could you explain more please?
Jun 08 13:08:08 <tbr> milad: I'd recommend to read a book about embedded linux
Jun 08 13:09:01 <milad> oh come on: read an entire book for changing a tiny logo?
Jun 08 13:09:27 <tbr> you seem to lack the basic understanding of embedded linux, so, yes.
Jun 08 13:09:32 <milad> if i had time i did but i need it earlier
Jun 08 13:10:25 <milad> i should do it today and may be i should read 1 page/sec
Jun 08 13:11:08 <tbr> why do you care about something as superficial as a boot logo if you have a deadline to meet?
Jun 08 13:17:48 <dogrocket> anyone know spi, i have beagle all hooked up thru device tree and everythings install but i dont know how to talk to codec thru spi
Jun 08 13:17:56 <dogrocket> i just want to know its responding
Jun 08 13:19:20 <milad> changing boot logo is vital for our company
Jun 08 14:38:29 <aef> is there any way to debug the boot process of the BeagleBone Black if it doesn't get as far as displaying things through HDMI?
Jun 08 14:50:54 <Defiant> aef: the serial
Jun 08 15:37:45 <aef> Defiant: how do i access that? is there an usb adapter?
Jun 08 15:37:53 <Defiant> aef: you have to buy one
Jun 08 15:38:32 <aef> Defiant: is there maybe a way that doesn't actually convert to the classic serial port but uses USB on both sides? because I don't have any PC that has a native serial port anymore
Jun 08 15:38:53 <Defiant> aef: http://elinux.org/Beagleboard:BeagleBone_Black_Serial
Jun 08 15:47:59 <yoyo> hey hi
Jun 08 15:59:45 <tbr> aef: just get a usb2serial cable. costs less currency units than a beer at the bar.
Jun 08 16:00:13 <tbr> bonus points if you buy one that uses the right voltage level out of the box (3.3V)
Jun 08 16:20:37 <aef> Defiant, tbr: thanks for the info
Jun 08 16:21:54 <aef> tbr: you recommended to use a specific kernel to me for my BBB. is there any info available on how to build that kernel by yourself?
Jun 08 16:26:28 <tbr> aef: I think the RCN kernel is on github. There are probably instructions on his pages how to build it.
Jun 08 18:13:47 <piranha32> has anybody tried to boot RCN's 3.7 kernel on BB-XM?
Jun 08 18:14:06 <vagrantc> why 3.7 specifically?
Jun 08 18:14:24 <piranha32> because it is supposed to support ulcd7
Jun 08 18:15:38 <piranha32> newer kernels don;t wirk, because there is not DT support for the board
Jun 08 21:43:59 <treeherder> guys i accidentally my MMC, what's a good resource for reconfiguring it with fdisk?
Jun 08 23:27:46 <treeherder>  feel like sucha  boss right now
Jun 08 23:28:01 <treeherder> upgrading my router from the command line with an image i compiled
Jun 08 23:31:51 <myself> while ssh'd in from another country
Jun 09 00:01:56 * piranha32 once recovered cluster of 32 computational nodes which crapped after kernel upgrade, while sitting on the other side of Atlantic Ocean
Jun 09 00:04:18 <foreverska> ya just gotta one up the kid dont'cha?
Jun 09 00:34:52 <foreverska> When you cast from (int32_t *) to (int16_t *) is the first 16 bits in [0] or [1]?
Jun 09 02:12:24 <jeronimo> hi folks. got a rev c and am a little confused at the readme.htm. it seems to be telling me to go to latest-images and install angstrom. but i thought rev c didn't do angstrom and came with debian
Jun 09 02:13:36 <veremit> lol documentatino fail
Jun 09 02:13:48 <veremit> yeah don't go back to angstrom
Jun 09 02:13:56 <veremit> only gonna cause you a headache
Jun 09 02:14:05 <jeronimo> yeah, no intention to
Jun 09 02:14:07 <veremit> there should be a debian image on latest-images ..
Jun 09 02:14:18 <jeronimo> i figured it was doc fail but checking since i'm new to BBB
Jun 09 02:14:27 <jeronimo> and the debian image there was all 2g
Jun 09 02:14:27 <veremit> but .. yeah .. that lot really needs a clear-up
Jun 09 02:14:30 <jeronimo> figured it'd be 4g
Jun 09 02:16:14 <veremit> w00t
Jun 09 02:16:16 <veremit> there we go again
Jun 09 02:16:39 <jeronimo> flaky connection?
Jun 09 02:17:03 <veremit> yeah terrible night for my 3G's .. both of 'em :(
Jun 09 02:17:26 <jeronimo> bleh
Jun 09 02:17:43 <jeronimo> so on http://beagleboard.org/latest-images they mention to different 2gig debian images
Jun 09 02:17:59 <jeronimo> do i need one of those? little confused at it being only 2gig. i thought it was bigger
Jun 09 02:18:15 <veremit> there shouldn't be a need for a bigger image :)
Jun 09 02:18:24 <veremit> or they haven't updated yet :p
Jun 09 02:19:01 <jeronimo> well, i thought the whole deal with the bump from rev b to c was they moved from 2g to 4g so they could fit in a proper debian. but i fully admit to not having read in depth
Jun 09 02:19:33 <veremit> its just ppl adding more packages used to run out of eMMC
Jun 09 02:19:42 <veremit> there's no need for a 'bigger' debian ..
Jun 09 02:19:53 <jeronimo> huh
Jun 09 02:20:35 <veremit> remember .. its not a desktop computer .. its an embedded processor board :)
Jun 09 02:21:13 <veremit> no 1TB disk drives and 16GB RAM lol
Jun 09 02:21:31 <veremit> scale Down! :)
Jun 09 02:22:02 <jeronimo> hey, i'm not the guy making the OS distribution ;)
Jun 09 02:22:31 <veremit> no .. the ppl that are know what they're doing .. trus tme :)
Jun 09 02:22:46 <jeronimo> never said they didn't
Jun 09 02:25:29 <jeronimo> any way to tell what debian image is currently on the bbb?
Jun 09 02:27:24 <veremit> probably .. but I don't know it :)
Jun 09 02:27:40 <Shadyman> Wow. Very Beagle. http://hackaday.com/2014/06/08/the-in-circuit-sd-card-switch/
Jun 09 02:29:14 <jeronimo> the BBB is set up to use dhcp if on ethernet, right?
Jun 09 02:29:16 <jeronimo> by default
Jun 09 02:33:35 <veremit> should dhcp on ethernet, yes
Jun 09 02:33:59 <jeronimo> cool, thanks. next step is to try to get an asus usb-n10 wifi adapter working with it
Jun 09 02:34:24 <jeronimo> seems like some people have gotten it working, at least with angstrom. but i haven't found any sort of format howto
Jun 09 02:34:30 <jeronimo> for debian
Jun 09 02:35:00 <veremit> oh joy .. good luck!
Jun 09 02:35:14 <foreverska> what comes up in dmesg when you plug it in?
Jun 09 02:35:18 <veremit> wifi seems very difficult .. but Oh So desireable
Jun 09 02:35:31 <veremit> I just plug my beagle in
Jun 09 02:35:32 <jeronimo> i haven't actually cut open the packaging yet. i was going to check if there was any "it just works" solution for debian
Jun 09 02:35:37 <veremit> if I want wifi .. I use the wandboard :D
Jun 09 02:35:45 <foreverska> Oh god no...
Jun 09 02:35:58 <jeronimo> unfortunately, the ethernet solution would involve me trying to run a cord through the wall to the second story of my 1933 house
Jun 09 02:36:04 <jeronimo> so its pick your poison
Jun 09 02:36:14 <veremit> buy an AP :) probably simpler
Jun 09 02:36:27 <foreverska> even when it "just works" you still have to dick around with all the rigamaro of WPA in debian without a wifi manager
Jun 09 02:36:36 <jeronimo> yeah, true. but it's JUST for the BBB, so it seems a little overkill
Jun 09 02:36:44 <jeronimo> bleh
Jun 09 02:36:49 <jeronimo> sometimes i really hate linux
Jun 09 02:36:59 <jeronimo> those times are when i have to do anything related to hardware setup
Jun 09 02:37:45 <jeronimo> the end goal for this is to serve octoprint for my taz4 3d printer, with a video feed
Jun 09 02:38:20 <veremit> cool
Jun 09 02:38:29 <veremit> some crazy innovative stuff going on
Jun 09 02:40:09 <jeronimo> i should probably just bite the bullet and try to just run a wire. it's actually in my office and i already have a dinky access point up there. i suppose i COULD just slap a hub on it.
Jun 09 02:40:22 <jeronimo> i think it only has two ports
Jun 09 02:40:59 <jeronimo> but man, the last time i tried to figure out the trajectory for getting the wire run, it gave me the willies. doesn't help that i have hardwood floors
