**** BEGIN LOGGING AT Sun Feb 07 02:59:58 2021 Feb 07 03:01:55 Oh. Feb 07 03:02:16 Well, the instructions are no good for what I thought they were going to be used to do. Feb 07 03:02:27 So, I kind of backed up in a corner for now. Feb 07 03:02:38 Reading will take place. Feb 07 03:12:15 I am not sure where to start for LCD panels dealing w/ FLIR stuff. So, I am out for now. Guessing first, shots in the dark, and then read, read, read. Feb 07 03:25:23 W/ SPI on this setup I have currently, BBGW w/ LCD Cape and FLIR Lepton v2 w/ cam, what is the master and would I use Linux as a slave for SPI at all? Feb 07 03:25:46 Theory. I can read in my spare time. Feb 07 03:26:24 I actually found a video, hence will brb, from FOSDEM17.org that highlights SZPI on 'embedded linux." Feb 07 03:26:49 Yikes. Sorry. SPI and not SZPI. Feb 07 11:48:56 Hi I have beaglebone black wireless and I have an issue with wifi module. Is there anyone who knows beaglebone wireless deeply Feb 07 12:37:48 INANC: tip: the best way to get help is to simply ask your question / explain your problem. plenty of knowledgable people glance at chat every now and then and may reply to questions if they have an answer or some suggestion Feb 07 12:38:24 while asking for someone to commit to support you with an unspecified problem will almost never get a response Feb 07 12:40:40 OK If I find someone to help me I will go in detail Feb 07 12:41:15 yeah, good luck with that Feb 07 12:41:20 ... did you even read what I just said? Feb 07 13:15:13 some people puzzle me Feb 07 13:36:39 * set_ puzzles? Feb 07 14:01:53 Is anyone messing w/ FLIR Lepton stuff w/ the BBB? I am asking b/c I am on p. 50 on a FLIR Lepton Datasheet and it seems there are only five pins needed to handle this breakout and cam. Feb 07 14:02:34 I thought, at first, I only needed SPI clock and data lines w/ GND and PWR/CMOS. Feb 07 14:03:41 Now, I have concluded that I need to have MISO so the slave can chat w/ the master. Feb 07 14:05:40 So, w/ MISO on the BBB, would writing a kernel driver or a userspace driver be better for this venture? Feb 07 14:07:28 For instance, I found that devicetree and drivers need to be there for utilizing the cam and breakout w/out using some lib. Feb 07 14:19:00 What is the MISO pin on the BBB? Feb 07 14:24:52 I found it on the BBBlue. Feb 07 14:37:04 set_ I recommend looking at the IO on the FLIR and the breakout information on the BBB header. You have at least 1 SPI port unallocated and it has MISO and MOSI IO already. SPI was made confusing by people at Motorola who are likely dead now (see 1980's). Feb 07 14:41:50 Oh. Feb 07 14:41:52 Okay. Feb 07 14:42:28 I found a couple of solid links. So, I need SCK /CS and MISO. Feb 07 14:42:52 Off to look those up. Feb 07 14:43:37 I was off on my wiring. Sheesh. Feb 07 14:44:19 I need the serial clock, chip select and MISO. Blah. Feb 07 14:45:08 I found a good link on elinux too about how to define, via devicetree, and find MISO and MOSI. Feb 07 14:45:15 set_ you do understand SPI don't you? Feb 07 14:45:23 A little... Feb 07 14:45:26 I have been reading. Feb 07 14:45:51 I am learning the datasheet and putting in tidbits here and there when I see something I do not understand. Feb 07 14:46:05 hmm have you ever used SPI Feb 07 14:46:11 Yes. Once! Feb 07 14:46:30 But, it was only four lines including the PWR/GND pins. Feb 07 14:46:36 So, I only used two pins really. Feb 07 14:48:15 that doesn't sound like SPI that sounds like a UART. Feb 07 14:48:53 I know. Feb 07 14:49:01 That is why I am clueless now. Feb 07 14:49:02 SPI has a lot of variations Feb 07 14:49:07 I understand. Feb 07 14:49:10 And modes! Feb 07 14:49:24 0 - 3 Feb 07 14:49:33 no you don't even with all the lines connected correctly you still have 4 possible configuration differences. Feb 07 14:49:53 I watched this hour long discussion on it and I have been reading. Feb 07 14:50:04 Right. Feb 07 14:50:11 right.. so do you understand what the modes are and why they are? Feb 07 14:50:44 Why they are, no. What the modes are, no. But, I can look them up again. I did not take notes. Feb 07 14:51:09 I know what you say...take notes. Feb 07 14:51:31 But...I was trying to listen to the talk and the doors kept slamming on his chat. Feb 07 14:51:48 Annoying. Feb 07 14:52:19 Okay. So, I am hardwired now. This is all fine and dandy. Feb 07 14:52:26 Five pin. Feb 07 14:52:39 you are aware of the 4 modes but don't understand them I guess? Feb 07 14:52:51 It is not that, i do not recall right now. Feb 07 14:53:15 You put me on the spot, matey. Feb 07 14:53:31 But...I will look it up again. Feb 07 14:54:11 right I didn't say know I said understand those are very different meaning words. Feb 07 14:54:18 Right. Feb 07 14:54:20 Okay. Feb 07 14:54:26 I could have used i2c. Feb 07 14:54:29 Sheesh. Feb 07 14:54:37 for example I know someones name but that doesn't mean I understand the person :D Feb 07 14:54:46 Right. Feb 07 14:54:47 Right. Feb 07 14:54:59 What if I knew the ideas you speak of? Feb 07 14:55:28 Would this chat go further? Feb 07 14:55:28 do you understand what polarity and phase are then? Feb 07 14:55:38 with regards to SPI. Feb 07 14:56:17 Stop. I understand so far that SPI handles serial communication by the falling or rising edge and w/ data and in time. Feb 07 14:57:21 W/out looking up external sources, that is what I have concluded. Feb 07 14:57:59 I understand that there are particulars. This is a big deal and I will deal w/ it in time. Feb 07 14:59:50 So, w/ my 'dev. kit,' it seems that I am using one of these modes. I read it but I would have to go back to read it again. Not noted. Feb 07 15:00:10 I knew I should have written it down. Argh. Feb 07 15:00:55 I have 14-bit data to handle w/ the grayscale video on this 'dev. kit.' Feb 07 15:01:05 this is why I told you to take notes. Feb 07 15:01:28 it's not just for remembering later LOL it's so you can remember later. Feb 07 15:01:50 Ha. Feb 07 15:01:52 Okay. Feb 07 15:02:09 I know we could have had a better discussion. Feb 07 15:02:16 * set_ owns up. Feb 07 15:02:33 so you need to know the polarity and phase they use on the SPI interface. Feb 07 15:02:44 Okay. Please hold. Feb 07 15:02:48 I will check. Feb 07 15:03:11 don't worry TI makes it's own mess of convoluted verbiage with regarding to SPI Feb 07 15:03:52 MODE 3 CPOL=1 && CPHA=1 Feb 07 15:04:37 It seems my scrolling back in time w/ that datasheet landed me right on the page! Feb 07 15:04:43 Ha. Feb 07 15:04:58 * GenTooMan waits for set_ to write things down. Feb 07 15:05:22 Paper, paper, paper. Oh and a pen! Feb 07 15:06:14 I am out of ink. Blah. Feb 07 15:07:12 Okay. Feb 07 15:11:01 I finally have notes. Nice. Feb 07 15:15:03 So, I am going to use Raw14 Mode to start on this dev. kit, which is default, and it is 160 bytes long. Feb 07 15:15:15 starters first. Feb 07 15:16:18 I would start with how to communicate BBB to FLIR actually. I'm sure the data sheet has a set of commands. Probably the best command to test is to check the FLIR status. Feb 07 15:17:29 Okay. Feb 07 15:18:18 I will look. There are two papers, i.e. a datasheet and what they call 'software interface description doc.' Feb 07 15:18:46 I am only on the datasheet right now. Feb 07 15:18:59 20 more pages! Feb 07 15:19:39 So, it seems that I was incorrect and that telemetry needs to be used for the default config, i.e. Raw14 mode. Feb 07 15:20:23 That is why I have 164 bytes instead of 160. Feb 07 15:23:30 I am stopping at thermal imaging basics for now, i.e. p. 63. Feb 07 15:24:14 GenTooMan: I looked in the kernel under tools for spi basics. Not so basic. Feb 07 15:24:35 Userspace may be easier on me to start. Feb 07 15:26:53 FLIR has a SDK. Feb 07 15:26:58 But... Feb 07 15:27:08 I cannot get it for some reason. Feb 07 15:27:25 I need to get on Ubuntu or Debian. Feb 07 15:28:01 heh? Feb 07 15:30:55 I tried on Win. Feb 07 15:30:57 So far. Feb 07 15:31:11 I have the sdk in .zip format. Feb 07 15:31:25 Three of them actually and there is a python section. Feb 07 15:32:04 But...I would need to install some other source to make everything work correctly. Feb 07 17:54:36 life is so much fun after rebooting (mutter). Feb 07 18:10:32 nah Feb 07 18:11:09 Have anybody run Android 10 - Android 11 on X15? Feb 07 18:31:18 hey, marcheu Feb 08 02:06:37 Well...and then some. **** ENDING LOGGING AT Mon Feb 08 03:01:12 2021
