**** BEGIN LOGGING AT Sun Mar 20 02:59:58 2016 Mar 20 03:51:47 <_ZeekHuge> hey ds2 ! Mar 20 03:52:56 <_ZeekHuge> can you please go through this :https://docs.google.com/document/d/1GfnoWusWUeH2VsLbt1qJaRi20uNxCC8O_Xw1CHoGY9A/edit Mar 20 03:53:22 <_ZeekHuge> will Wormo be here ? Mar 20 04:01:06 nerdboy, will Wormo be here ? Mar 20 04:01:32 not sure Mar 20 04:01:44 might be game night Mar 20 04:01:53 ohk ... I have added some details to this https://docs.google.com/document/d/1GfnoWusWUeH2VsLbt1qJaRi20uNxCC8O_Xw1CHoGY9A/edit Mar 20 04:02:34 also .. can the proposal window be kept open ? for a few more days ? if a mentor wants ? Mar 20 04:04:00 that should be on the timeline Mar 20 04:09:03 25th is the last day no late exceptions Mar 20 04:09:26 okay.. Mar 20 04:11:47 that's what it says on the jkridner post, also on google-y timeline Mar 20 04:12:03 people should really read the fine stuff... Mar 20 06:25:54 Hi ZeekHuge Mar 20 06:26:01 Hey Wormo ! Mar 20 06:26:09 whats your timezone ? Mar 20 06:26:14 PST Mar 20 06:26:32 but I like staying up late Mar 20 06:26:49 https://docs.google.com/document/d/1GfnoWusWUeH2VsLbt1qJaRi20uNxCC8O_Xw1CHoGY9A/edit Mar 20 06:26:58 can you comment on this please .. Mar 20 06:27:24 though trying not to stay up too late tonight (tomorrow is Sunday, my church meets in morning) Mar 20 06:27:25 would you like to mentor this project ? Mar 20 06:28:21 just a quick read ? Mar 20 06:28:25 ZeekHuge: I was just reading it :) Mar 20 06:29:11 main question for now is if you've found any ADC yet that you want to try Mar 20 06:29:47 There are a few . . . I was thinking to use an evaluation board Mar 20 06:30:05 will that be fine ? Mar 20 06:30:24 yeah, what about the camera interface? Mar 20 06:30:26 yes eval board is suitable, but mention which Mar 20 06:30:36 ohk . Mar 20 06:33:30 camera interfaces ? Mar 20 06:34:32 like people hooking up the ADC into camera interfaces ? Mar 20 06:35:04 I think he means using the PRU parallel bus to capture from parallel camera interfaces Mar 20 06:36:15 oh .. ohk ! Well the idea is to make the PRU as a parallel bus .. in the generic and generalized form. So whatever the driver would want to do, it can do with it .. Mar 20 06:47:13 Wormo, still reading ? Mar 20 06:49:05 I see you're still working on the section about proposed software implementation Mar 20 06:50:02 yes but .. how about the direction ? Mar 20 06:50:24 and also would you like to mentor this project ? Mar 20 06:50:41 It makes sense to me, more specifics on the initial ADC and the software are still needed Mar 20 06:51:49 I think we're not supposed to talk about which projects will be selected... everybody needs to wait for google to announce Mar 20 06:52:42 No no ... I mean, the procedure says that "propose an idea and get a mentor is interested in that"... so I am talking about that part .. Mar 20 06:54:09 oh well.. maybe, I've not done PRU yet, so would be best to have somebody with PRU experience chip in Mar 20 06:54:24 normal kernel drivers I have done Mar 20 06:54:30 ohk .. nerdboy ? Mar 20 06:54:47 or ds2 ? you there ? Mar 20 06:56:42 probably idle, I'm up late for PST Mar 20 06:57:12 about midnight Mar 20 06:57:26 ohk .. any comments on adding details ? or corrections ? Mar 20 07:00:44 add the info for your proposed ADC eval board, and talk about the relationship between your new code & driver subsystems you plan on using (remoteproc, IIO, etc) Mar 20 07:02:01 aa.. yes .. ohk Mar 20 07:02:16 e.g. how wide is the data for this eval board, what level voltages (need level shifters?) stuff like that Mar 20 07:02:35 link to the datasheet Mar 20 07:02:43 right ... will do. Mar 20 07:02:49 and ? Mar 20 07:03:53 i'm not pru guy either Mar 20 07:04:11 although it's not really rocket science Mar 20 07:04:25 ohk .. but anything on the doc ? Mar 20 07:04:36 we got to write some drone-y specs Mar 20 07:05:00 *she* worked on the thermal camera thingie Mar 20 07:05:36 go ahead and keep adding some detail Mar 20 07:05:49 okay . Mar 20 07:12:47 also once you get the adc board datasheet, look at the timing diagrams for the parallel outputs and see how you're supposed to clock in each data sample Mar 20 07:13:34 okay .. searching ADC. Mar 20 07:13:40 http://www.digikey.com/product-search/en/programmers-development-systems/evaluation-boards-analog-to-digital-converters-adcs/2622527 Mar 20 07:26:49 how about this ? http://www.digikey.com/product-detail/en/texas-instruments/TLV5535EVM/296-10731-ND/381828 Mar 20 07:27:27 though I am aiming to get a sampling rate of 40Msps, is it ok to use an ADC with lower sampling rate ? Mar 20 08:00:01 any suggestions on the Proposal draft .. ? anyone ? Mar 20 08:05:07 that one says "Obsolete item" not available Mar 20 08:05:46 yes it doesn't have to be full 40Msps to be of interest Mar 20 08:06:09 just not low speed like the 1MHz example Mar 20 08:07:10 oh ! ohk, I missed that "Obsolete item" thing.. Mar 20 08:07:12 sorry . Mar 20 08:08:48 you want to make sure any hardware needed is available and no lead time Mar 20 08:18:54 maybe something like this http://www.digikey.com/product-detail/en/linear-technology/DC782A-P/DC782A-P-ND/4766042 Mar 20 08:19:19 gnight Mar 20 08:19:28 http://www.digikey.com/catalog/en/partgroup/ltc2226h-and-ltc2246h-demonstration-boards/59211?mpart=DC1350A-B&vendor=161&WT.z_ref_page_type=PS&WT.z_ref_page_sub_type=PD&WT.z_ref_page_id=PD&WT.z_ref_page_event=DC_Link_Table Mar 20 08:19:31 as similar one Mar 20 08:19:38 ohk .. good night :) Mar 20 10:56:20 panto-cloud: there?? Mar 20 13:57:05 Anybody knows some intricate details in ardupilot? Mar 20 14:15:28 hello icant seem to find my mentor can any body help Mar 20 14:25:32 i have come up with a own project and i need to know who is gona be my mentor Mar 20 14:26:45 the idea ia QR code based security system based on this http://beagleboard.org/project/rfid-authentication-for-hacker/ Mar 20 15:42:32 alexhiam, ds2,Are you there?I have some doubts regarding Rpmsg Mar 20 15:50:11 Is anybody familiar with Shubanghi Gupta's work last year?? Mar 20 15:50:16 pruss for newer kernels?? Mar 20 16:43:13 "Fix my supper, baby, let me go to bed... Guess that white lightnin' done gone to my head" Mar 20 18:41:34 * nerdboy still waiting for sonic anemometer proposal... Mar 20 19:02:30 hey ds2 ! you there ? Mar 20 19:54:21 Hey nerdboy, ds2 ! Mar 20 19:54:53 I have submitted my proposal for the project "Port/implement MAV (drone) stereo image processing , using the BeagleBone Black (via BBIO cape) as Ardupilot platform" Mar 20 19:55:38 Can I know your thoughts about it ? Mar 20 20:14:47 i don't see it in the google-y list... Mar 20 20:15:11 nerdboy, does the proposal have some limits ? Mar 20 20:15:27 I mean does it need to fit within some number of pages or so ? Mar 20 20:15:30 not sure what you mean Mar 20 20:15:37 size limit? Mar 20 20:15:44 yes size limit Mar 20 20:16:14 not sure, whatever the student submission guidelines say... Mar 20 20:16:30 nerdboy,could you guide me a bit about rpmsg? Mar 20 20:16:31 * ZeekHuge remembers that alexiam said its just the patience of the mentor. Mar 20 20:19:06 nerdboy,In it we are basically communicating using two Vring data structures and message inboxes between the PRU and ARM. Mar 20 20:20:37 nerboy,I don't understand how will we perform ioctl operations on it?I mean ioctl commands are fixed for a particular core?Would we have write a new set of ioctl commands for it? Mar 20 20:23:40 no idea Mar 20 20:24:09 but i thought you weren't using the msg interface directly Mar 20 20:24:48 aren't you using virtio interface? Mar 20 20:29:36 Well I am just exploring the options. Mar 20 20:30:29 It wouldn't be wrong to write all the options along with their merits and demerits(that I can find) in the proposal right? Mar 20 20:31:25 I mean it is pretty difficult to decide on one way without extensive testing. Mar 20 20:33:18 you should be able to eliminate based on theoretical overhead/performance Mar 20 20:35:32 okay.Any idea when Alexhiam or ds2 will be online? Mar 20 20:50:36 not really, they're back east and i'm not Mar 20 23:09:04 yashoza: can you upload a draft doc into the gsoc thing? Mar 20 23:12:27 or link your google-y doc or whatever... Mar 21 00:57:39 nerdboy : Sorry, I went for a nap! Mar 21 00:57:46 The link : https://groups.google.com/forum/#!topic/beagleboard-gsoc/qD_hMQg_uww Mar 21 00:58:41 I have written the project briefing accurately, but I still want your help with setting up the timeline perfectly Mar 21 01:03:23 Link to the Google doc : https://docs.google.com/document/d/1WDq5zcQAIUx6BA3M5C4u7m_gzjdtIAhn28mI-8iMgkQ/edit Mar 21 01:11:57 oh, can you add some detail on the capture interface? Mar 21 01:12:10 lepton is spi? Mar 21 01:26:53 that was quick... **** ENDING LOGGING AT Mon Mar 21 02:59:58 2016
