Jul 29 08:02:25 <karki> :0
Jul 29 08:32:08 <Abhishek_> Morning
Jul 29 11:52:54 <karki> panto alexanderhiam jkridner : I have a I have while(1) {__R30 = 2;} on PRU1; i'm getting 1.3V op
Jul 29 11:53:09 <karki> on pin r30[1]
Jul 29 11:53:19 <karki> if I do __R30 = 1
Jul 29 11:53:51 <karki> I get 3.3V on pin r30[0]
Jul 29 11:53:57 <karki> which is as expected
Jul 29 11:54:19 <karki> idk why r30[1] is giving me weird problems
Jul 29 13:20:11 <Abhishek_> hi jkridner
Jul 29 13:37:28 <Abhishek_> jkridner: There are serious scaling issues with using WaveDrom for rendering the logic waveforms; anything more than ~4K of samples is very likely to freeze the browser window for a couple of seconds
Jul 29 13:39:42 <Abhishek_> jkridner: I am pushing the work on the web interface so far, wanted to know if you could check it out when you have got some time
Jul 29 14:05:24 * karki wonders where everyone is...........
Jul 29 14:05:49 <Abhishek_> not far
Jul 29 14:19:13 <alexanderhiam> karki: R30[1] is muxed to the LCD_DATA1 signal on the schematic, which is one of the boot config pins with a 100k pull-down resistor on the board
Jul 29 14:21:08 * vvu vvu is here but still in the shadows
Jul 29 14:23:23 * alexanderhiam has to reboot into windows now :(
Jul 29 16:08:25 <Abhishek_> karki: does it still read 1.3 V?
Jul 29 16:08:35 <karki> hhmm
Jul 29 16:08:39 <karki> not sure
Jul 29 16:08:45 <karki> should check.
Jul 29 16:09:00 <karki> why? do you have a solution  :)
Jul 29 16:09:25 <Abhishek_> nope; just wondered if the issue is still there
Jul 29 16:09:31 <Abhishek_> *wondering
Jul 29 16:11:01 <Abhishek_> btw, got wavedrom to render dynamically generated signals today
Jul 29 16:11:04 <karki> it's the weirdest of problems I've encountered
Jul 29 16:17:28 <alexanderhiam> karki: I answered ^above^ at some point, that pin is muxed to the signal labled LCD_DATA1 on the schematic which is used for the SYSBOOT1 bit in the boot configuration and has a 100k pulldown on the board
Jul 29 16:18:29 <karki> but the pin muxing has been done properly.......
Jul 29 16:18:39 <karki> and sometimes it works fine
Jul 29 16:18:44 <karki> sometimes it doesnt
Jul 29 16:18:49 <Abhishek_> karki: Have you disabled the HDMI cape?
Jul 29 16:18:51 <alexanderhiam> wiat, you're driving it high though?
Jul 29 16:18:57 <karki> yeah
Jul 29 16:19:07 <karki> __R30 = 0b01;
Jul 29 16:19:11 <karki> I get 3.3V
Jul 29 16:19:20 <karki> put it in a loop I get 1.3V
Jul 29 16:19:27 <karki> no joking
Jul 29 16:19:33 <karki> I double checked
Jul 29 16:19:38 <alexanderhiam> nevermind, with the 100k pulldown 1.3v would mean an output impedance of ~150k
Jul 29 16:19:48 <karki> re booted the BBB, now it's fine
Jul 29 16:20:07 <Abhishek_> today's screenshot: http://s29.postimg.org/uh1mktxid/Screenshot_from_2014_07_29_19_50_44.png
Jul 29 16:20:08 <karki> giving me 1.66V at 50% duty cycle in soft PWM
Jul 29 16:20:29 <alexanderhiam> karki: do you have a scope?
Jul 29 16:20:39 <karki> nope :(
Jul 29 16:21:19 <alexanderhiam> what meter are you using?
Jul 29 16:22:36 <alexanderhiam> digital?
Jul 29 16:26:53 <rseethamraju> Abhishek_: cool!
Jul 29 16:32:13 <karki> alexanderhiam : yes, a multi meter!
Jul 29 17:02:12 * karki hates interviews :(
Jul 29 17:03:19 <Abhishek_> clearly indicates that you just rocked one :)
Jul 29 17:04:00 <karki> nah, interviews start tomorrow, I'l be going for ebay on friday though
Jul 29 17:04:14 <Abhishek_> All the best :)
Jul 29 17:04:18 <karki> I don't see the meaning behind interviews
Jul 29 17:04:22 <karki> thanks :)
Jul 29 17:04:53 <karki> like 2-3 hrs with the person is good enough to know whether he/she is worth it?
Jul 29 17:05:49 <vvu> karki: did you prep hardcore for algo questions ?
Jul 29 17:05:55 <Abhishek_> might not be good enough, but there's no better option actually
Jul 29 17:06:12 <karki> vvu : no, and that is the problem
Jul 29 17:06:15 <karki> :p
Jul 29 17:06:39 <karki> I don't get the point of sitting and solving complex questions on paper
Jul 29 17:07:00 <Abhishek_> as embedded developers, we might be spared that
Jul 29 17:07:24 <karki> and the 'complexness' of those questions are *much* different than any real world application need.
Jul 29 17:09:02 <karki> For a backend cloud engineer I don't find the point of some really convoluted on paper problem. Rather it's more advantageous to understand distributed systems, virtulization etc
Jul 29 17:09:27 <karki> ARM didn't bother with any of those luckily
Jul 29 17:09:29 <karki> :)
Jul 29 17:09:36 <Abhishek_> Well, IIRC a recruiter had pointed out that competitive programming had no meaning on the CV
Jul 29 17:09:45 <Abhishek_> (on Quora)
Jul 29 17:09:48 <karki> Robert Love
Jul 29 17:11:05 <karki> competitive programming as an element on the resume may not be a big thing, but the fact that it teaches you to solve algorithmic questions is what makes the difference.
Jul 29 17:11:43 <karki> thats why it seems that competitive programming is a big thing to have on your resume
Jul 29 17:11:53 <karki> doesn't apply for embedded folk though
Jul 29 17:13:14 <Abhishek_> yep, embedded seems to be a different ball game altogether
Jul 29 17:17:33 <karki> I've seen many a competitive programmer who've lost their mind trying to get around hardware :p
Jul 29 18:12:51 <Abhishek_> karki: you could say that they are nearly "orthogonal" skills
Jul 29 18:16:54 <_av500_> praveendath92: ping
Jul 29 18:18:45 <praveendath92> _av500_: pong
Jul 29 22:12:31 <Abhishek_> @All: http://beaglelogic.github.io/webapp/
Jul 29 23:53:30 <vvu> Abhishek_: 404
Jul 29 23:53:53 <Abhishek_> vvu: I've repushed the site and I'm getting the same error too
Jul 29 23:54:02 <Abhishek_> It was functional an hour ago
Jul 29 23:54:16 <vvu> :(
Jul 29 23:54:39 <vvu> maybe they are just refreshing stuff
Jul 29 23:54:55 <vvu> changes do not get reflected fast
Jul 29 23:55:27 <vvu> oh well gn Abhishek_ !
Jul 29 23:55:32 <Abhishek_> No actually I had created a new repo for the web page, and then I deleted it, and created it again as a spin-off of the main repo
Jul 29 23:55:44 * vvu lurks in the shadow
Jul 29 23:55:54 <Abhishek_> gn vvu
Jul 29 23:56:14 * Abhishek_ is going to sleep in the mornine lecture today
Jul 29 23:56:19 <Abhishek_> *morning
Jul 29 23:57:42 <vvu> that is the spirit!
Jul 30 01:19:59 <Abhishek_> vvu: The issue was with github, I got it resolved via IRC
