**** BEGIN LOGGING AT Fri Apr 10 02:59:57 2020 Apr 10 03:00:12 https://howthingsfly.si.edu/flight-dynamics/roll-pitch-and-yaw <<< This is an "informative" rendition of info. Apr 10 03:00:33 For flight, at least, that page does its job. Apr 10 03:01:15 flight or fight? Apr 10 03:01:32 Green is for Growbotics Apr 10 03:02:32 Well, I am fighting it so far but in the name of flight. Apr 10 03:02:46 i just bough the black so my green is freed up Apr 10 03:02:51 what is growbotics Apr 10 03:02:51 Nice. Apr 10 03:03:17 i guess it kind of makes sense since it is made by Seeed Apr 10 03:03:18 lol Apr 10 03:03:39 set_ you only need to get 1 motor going the right direction then alternate the direction for each proper per motor as you go clockwise from that one Apr 10 03:03:57 Oh. Is that all? Apr 10 03:04:09 if you had one motor blowing just use the oposite direction prop yes that's all Apr 10 03:04:20 I tried. Apr 10 03:04:26 It did not work. Apr 10 03:04:38 I rearranged the props earlier. Same effect. Apr 10 03:04:47 * GenTooMan practices his confused look and fails. Apr 10 03:05:01 I just shook my head from left to right. Apr 10 03:05:03 Okay. Apr 10 03:05:09 So you have one prop correct? Apr 10 03:05:17 Two are correct. It is a quad. Apr 10 03:05:39 Two are a bit confused and two are just right. Apr 10 03:05:43 go the side oposite and try the same direction prop? Apr 10 03:05:57 If two have props and are wrong flip the props? Apr 10 03:06:49 I exchanged them out for one another instead of flipping them. Apr 10 03:06:54 Ba. Apr 10 03:07:06 I need to flip 'em instead. Apr 10 03:07:19 It is like a three year puzzle. Apr 10 03:07:47 Oh well. Not tonight. I will do it tomorrow during our April shower. Apr 10 03:07:53 well swap not flip if you swapped them that should work Apr 10 03:08:02 I swapped 'em. no good. Apr 10 03:08:12 They both still blow upward. Apr 10 03:08:36 The mfg. could be playing a joke on me. Apr 10 03:08:40 Who knows? Apr 10 03:08:56 I have some other five inch props. Apr 10 03:09:04 I should try those too. Apr 10 03:09:10 brb Apr 10 03:13:33 Okay. I am going to take a photo and annotate it. This should solve some questions. Apr 10 03:19:44 well you could have the wrong props on both of them woo hoo? Apr 10 03:21:09 I know. Apr 10 03:21:12 It is odd. Apr 10 03:21:23 I have been battling this prop biz for a year now. Apr 10 03:21:29 well if you have more props look at ones that thread the oposite direction Apr 10 03:21:34 There are unlimited configs. Apr 10 03:23:18 https://drive.google.com/file/d/1rCk-QdQQvOaGK5IlUFFa2DDElVT_mIjO/view?usp=sharing is the idea so far. Apr 10 03:23:37 Oh and yes sir, the reverse threads are a pain too. Apr 10 03:24:56 So, in that photo... Apr 10 03:25:11 The bottom left and top right are the reverse threads. Apr 10 03:30:59 sorry. Scratch that idea from above this line. Apr 10 03:31:08 Bottom right and bottom left are reverse threaded. Apr 10 03:31:31 Should I exchange out the motors for different positions? Apr 10 03:33:17 https://drive.google.com/file/d/1rCk-QdQQvOaGK5IlUFFa2DDElVT_mIjO/view?usp=sharing there. Apr 10 12:41:16 back Apr 10 12:42:40 i am not sure if anyone responded to my plight Apr 10 12:42:43 i may of missed it Apr 10 12:42:46 got disconnected Apr 10 12:47:37 MattB0ne: there has been no messages in chat in the 9 hours before you said "back" Apr 10 13:06:36 :D Apr 10 13:07:50 MattB0ne I think zmatt is infering if you had a plight those on the channel are likely unaware Apr 10 13:09:06 *implying Apr 10 13:09:14 but yeah Apr 10 13:11:51 you have not (successfully) communicated any plight recently Apr 10 14:03:10 hmmm Apr 10 14:03:24 well i am getting the message Apr 10 14:03:25 qt.qpa.screen: QXcbConnection: Could not connect to display Apr 10 14:03:36 if I run my program with ssh -X Apr 10 14:03:38 it works Apr 10 14:03:46 but I cannot get my cape to show my program Apr 10 14:03:54 the cape is working Apr 10 14:04:08 before I flashed it was functional and after flashing to buster I see the logon Apr 10 14:04:53 when I ssh into it the screen does not change. I am not sure how I can tell the beagle where the display is Apr 10 14:04:54 if you want to run the program with X11 then you'll need X11 running (and, if trying to start the application via ssh, you should have the DISPLAY environment variable setup to ":0") Apr 10 14:05:04 though qt5 applications usually don't require X11 Apr 10 14:05:17 but using a different QPA may require setting up some other environment variables Apr 10 14:12:02 MattB0ne: if you want to try running a qt5 application without X11, this may be of use: https://pastebin.com/SHw7VjWd Apr 10 14:13:03 (using qt5 with egls should also be possible but requires a bit more effort) Apr 10 14:13:07 *eglfs Apr 10 14:25:29 zmatt: thanks for the link Apr 10 14:25:32 will check it out Apr 10 14:30:40 I remember that last time I fiddled with it (which is quite a while ago) I also needed to setup some variables to get input working right Apr 10 14:31:03 and it had a habit of making the cursor of my ssh terminal invisible... there was a way to prevent it from doing that but I can't remember Apr 10 18:12:02 Good might bb community Apr 10 18:12:26 I have a questin about the bb AI Apr 10 18:14:09 As far as the datasheet of the mpu says that the pru's incorporate delta sigma demodulator Apr 10 18:14:21 With the sinc filters Apr 10 18:15:16 Does the bb AI entire drivers support this interface Apr 10 18:16:02 As the project we are working requires 7 channel of this peripheral this topic is important for us Apr 10 18:16:15 drivers? I don't see what drivers have to do with this Apr 10 18:17:11 Lets name them sdk Apr 10 18:17:45 also, are you sure the am572x PRU supports this? I know I've seen the feature on some recent TI SoCs but I'm not sure the am5729 is one of them Apr 10 18:18:31 Let me check again on pinmux Apr 10 18:19:03 Just a moment Apr 10 18:20:17 there's no mention of it in the PRU chapter of the AM572x TRM, and bits 26-29 of the PRUSS_GPCFG registers (which would be used to select this mode) say "Reserved. Keep at reset value." Apr 10 18:21:22 though it could be a TRM error or a censored feature (wouldn't be the first time) Apr 10 18:21:33 Yes you are right Apr 10 18:22:16 Sigma delta decimator is on 571x and 574x Apr 10 18:24:26 As this feature is very important for us maybe someone here can guide us on using this pru feature Apr 10 18:25:02 If possible it will be nice to get help on am437x platform Apr 10 18:25:35 that's out of scope for this channel, it would be more appropriate to ask TI on their forum (e2e.ti.com) Apr 10 18:26:14 Okay zmat thank you Apr 10 18:33:16 For many things like that it's best to ask TI directly as they say. Apr 10 18:42:20 is there a quick way to findout how your system is labeling displays and scrrens Apr 10 18:42:23 is there a file somewhere Apr 10 18:42:32 what do you mean by "labeling" Apr 10 18:45:03 like 0:1 vs 1:0 Apr 10 18:45:10 the number of the device and screen Apr 10 18:45:17 oh you're talking about X11 Apr 10 18:45:21 yeah Apr 10 18:45:27 i guess Apr 10 18:46:02 are there alternatives to x11? that is the same as xorg right? Apr 10 18:48:47 x11 (often shortened to just "x") is the general system, xorg is the x11 implementation by the X.Org Foundation, which is the only maintained x11 implementation afaik Apr 10 18:49:11 ok Apr 10 18:49:31 i installed xorg but I cannot run functions like XScreenCount() Apr 10 18:50:26 the alternative would be Wayland or not using a window system at all (which is often fine for single-window-fullscreen applications, e.g. for touchscreen interfaces in embedded applications) Apr 10 18:51:40 whats your recommendation. I am making a single window application Apr 10 18:53:05 and I'm not sure if multiple screens (in the old x11 meaning of the word) are still supported, normally if you have multiple physical screens on one x11 server they're glued together to form one screen (which is what people usually expect), so the part after the "." in DISPLAY will always be 0 in practice nowadays Apr 10 18:54:03 I'd personally not bother with x11 for a single-window qt5 application, which is why I suggested using its linuxfb backend Apr 10 18:55:33 ok Apr 10 18:56:12 but different people have different opinions about this, so I suggest you form your own Apr 10 18:56:43 some feel using x11 is easier, I felt it was just an unnecessary headache Apr 10 19:02:28 btw if you're curious about the precise meaning of the DISPLAY variable: https://www.x.org/archive/X11R6.8.1/doc/X.7.html#sect4 Apr 10 19:04:16 the only part they don't clarify is that when TCP is used, the port number is 6000+displaynumber, so since the screennumber is basically unused and superfluous nowadays, it's essentially just "hostname:port" except for 6000 being subtracted from the port number Apr 10 19:05:03 the connection to the default display (:0) however typically doesn't use TCP but a local unix domain socket Apr 10 19:05:35 which is faster and a tad more secure. Apr 10 19:06:24 X real strength is for headless display IE no local display hardware you can use a remote display with it. Apr 10 19:17:00 it seems that on linux, if the hostname is omitted it will try the following ways to connect: https://pastebin.com/KSRbyWHe Apr 10 19:17:51 which is quite an enigmatic order to try things in... why try ipv4 first for udp but ipv6 first for tcp? why prefer udp over tcp, yet it doesn't use SOCK_DGRAM or SOCK_SEQPACKET for AF_UNIX ? Apr 10 19:18:57 I wasn't even aware x11 ever used udp Apr 10 19:24:34 GenTooMan: Whenever you want to get involved w/ this fascination of flight again, https://ardupilot.org/copter/_images/motororder-quad-x-2d.png. Apr 10 19:24:35 ... Apr 10 19:24:55 I will attempt to try that idea out. Apr 10 19:33:01 weird, based on the libxcb source code it shouldn't attempt to use udp, only tcp... yet strace says otherwise Apr 10 19:33:15 set_ you do realize the props you have are all ccw you need 2 cw props for things to work right don't you? and you can tell which rotation the prop goes Apr 10 19:33:49 GenTooMan: How do you know? Apr 10 19:34:43 My props should have been cw and ccw too. I will go and look again. Apr 10 19:34:52 set_ I can see what the leading edge is on the prop as I've used so many of those props Apr 10 19:35:07 Oh. Apr 10 19:35:29 Okay. The larger, fatter side of the prop goes against the wind, right? Apr 10 19:36:06 So, if my blades/props are turning, the fatter/larger side hits the air first? Apr 10 19:36:50 set_ right .. or look at it like it's a screw which way will it thread toward you when you turn it? Apr 10 19:37:42 Okay. Apr 10 19:38:15 The props have a larger side and a thinner side. I need to have the large side got against the air. Okay. Apr 10 19:38:57 zmatt hmm I only spent a terse amount time with it, UDP though is faster and IP4 is probably less over head to use maybe? Apr 10 19:39:51 set_ thing of going in the direction of movement ... that determines the direction of the pitch. Anyhow if you have more props go look at them and find the ones that go the other way that are the same pitch and diameter. Apr 10 19:40:14 GenTooMan: I'm pretty sure X11 doesn't support udp though, I haven't found any evidence of that, so I'm quite puzzled why I'm seeing attempts to connect via udp via strace Apr 10 19:41:29 (and the question wasn't why ipv4 over ipv6, the question was why, based on strace, it seems to use the order udp4, udp6, tcp6, tcp4 ...) Apr 10 19:41:34 zmatt is it used with 127.0.0.1? Apr 10 19:41:46 it's like getaddrinfo is ignoring the SOCK_STREAM specification Apr 10 19:44:40 yeah I'm not seeing that behaviour if I specify a hostname (although things are quite puzzling in that case too, since I gave it a hostname that has both an ipv6 and ipv4 address, but it only attempted to connect to ipv6 and then gave up) Apr 10 19:46:34 hmm interesting ... you are making me want to set up a window display on this machine and setting and running a X program on my BBB Apr 10 19:47:21 I need to have complete thoughts expressed in my sentences ... really. Apr 10 19:47:28 oh I'm just testing on my laptop with e.g. DISPLAY=:1 strace -e trace=connect,socket xeyes Apr 10 19:48:12 I never run X11 stuff on a beaglebone Apr 10 19:53:02 zmatt: this line QT_QPA_PLATFORM=linuxfb:tty=/dev/tty1 works Apr 10 19:53:03 sort of Apr 10 19:53:17 i get a permission denied but I see my widget on the lcd cape Apr 10 19:53:41 the size is wrong so I cannot close it Apr 10 19:53:55 and killing the process does not clear the widget from the cape Apr 10 19:54:26 if it's using the legacy fb interface then it won't clear the screen on exit Apr 10 19:56:03 is it stuck in a loop re running the program i get display error again Apr 10 19:56:21 ? Apr 10 19:57:09 please just share the command(s) you used + full output using pastebin (or similar paste service) Apr 10 19:59:03 as for the size, I'd assume the top-level window is automatically resized to the screen size but I'm not sure about that... Apr 10 19:59:29 do I remember correctly that you're using debian buster, or are you using stretch? Apr 10 20:00:02 i am on buster Apr 10 20:00:30 okay, so qt 5.11 .. then yeah, the docs say "the first top-level window is forced to cover the entire screen" Apr 10 20:01:04 ... Apr 10 20:01:11 GenTooMan: You were right. Dang props. Apr 10 20:01:28 The co. sold me cw as cw and ccw. They lied. Oh well. Apr 10 20:01:31 MattB0ne: are you testing with QT_QPA_FB_DRM=1 or without that? Apr 10 20:06:54 i ran it first without it Apr 10 20:06:59 I am going to reset and set to 1 Apr 10 20:08:16 set_ be sure to match the cw and ccw prop diameter and pitch and you should be fine. Apr 10 20:09:07 I did. five inches. Apr 10 20:09:27 All four are five inches and the pitch, cough, might not be the same. Apr 10 20:09:39 set_ um that's the diameter there should be 2 numbers 5-2 or something Apr 10 20:09:45 I have two sets of two. Each of are different pitch. Apr 10 20:10:25 they sold you the wrong stuff no wonder you had troubles. Apr 10 20:10:29 It flips easy now. I cannot wait to take it outdoors. It is way too wild thus far for indoor use. Apr 10 20:10:32 No joke! Apr 10 20:10:49 I was like der when I should have been like wow? Apr 10 20:10:53 Ha. Apr 10 20:11:20 well check amazon for props for it? and get a proper matched set. Apr 10 20:12:37 Anyway, I have three sets of props w/ all matching characteristics/diameter. I just need to figure out if they are cw and ccw now. I know some, at least two of one set, is ccw. Apr 10 20:13:33 Oh the glory of bots! Apr 10 20:17:01 well from the immage the yellow and dark orange ones are all CCW so check the leading edge on the remaining 2 if they are facing a different direction you have the props Apr 10 20:18:31 also you need to swap motor wires so side oposits turn the right direction. Apr 10 20:30:59 Okay. Apr 10 20:31:29 Right now, all wind is headed downward through my props. Apr 10 20:39:09 I do not catch any breezes looking down on my bot while I trottle my motors lightly. Nice! Apr 10 20:43:21 Ok however if you look at the diagram on page one of the setup you need to reverse 2 of your motors. Apr 10 20:45:09 look at your google drive and compare notes Apr 10 20:45:15 image that is. Apr 10 20:47:45 Okay. Apr 10 20:48:34 No issue. So, the motors need to turn cw and ccw, like in the image, and the corresponding props need to be set as cw or ccw too? Apr 10 20:48:46 right Apr 10 20:48:49 Oh. Apr 10 20:48:51 Got it. Apr 10 20:48:52 Okay. Apr 10 20:48:56 then it will work correctly Apr 10 20:49:11 For stability and flight control, got it. Apr 10 20:49:16 do you know about prop torque? Apr 10 20:49:23 Not yet. Apr 10 20:49:29 I mean, no. Apr 10 20:50:08 I have read about it before on specific sites but it does not ring a bell right now. Apr 10 20:50:47 I think when I was bogged down reading too often, things started to get conflicted. My readings were not all associated w/ one another. Apr 10 20:51:06 So, it was this topic this day and that topic the next day. Apr 10 20:51:24 None of which were looking back at the pervious subject matter. Apr 10 20:51:33 sorry. previous. Apr 10 20:52:31 Now, it is time to figure out which of my motor turn correctly and then add the props later. Apr 10 20:52:41 in any case prop torque will cause the quad copter to spin weird if not negated that's why they have 2 CCW and 2 CW they need to be staggered so it actually works correctly is all. Apr 10 20:52:55 Okay. Apr 10 20:55:05 prop torque is friction drag? Apr 10 20:57:52 have you ever tried to put a screw into something that's not held fast? It turns right? That's what happens with a prop without something to resist it's rotational torque. Apr 10 21:00:25 hence why planes have vertical stabilizers and helicopters have that small rotor to keep the thing from spin crazily. Apr 10 21:00:36 Okay. Okay. Apr 10 21:00:53 Look here: I found the drag coeffecient and some nasa explanation on the whole entity. Apr 10 21:00:59 https://www.grc.nasa.gov/www/k-12/airplane/drageq.html Apr 10 21:01:03 Simplistic terms. Apr 10 21:01:25 Sort of. Apr 10 21:02:14 I have to experiment to receive Cd, i.e. which is what i like to do but might never have the equipment to do so. Apr 10 21:02:36 So, no space time for me but nevertheless, it is interesting. Apr 10 21:02:45 well as is you may be able to fly your quad copter but it likely will drift some Apr 10 21:03:14 Right. Drifting, flipping, crashing, flying away on its own, and etc. Apr 10 21:03:44 GenTooMan: Did you see the fellow that put his drone w/ the BBBlue on a leash and documented it? Apr 10 21:04:22 Supposedly, the 35 to 50' leash kept the FAA from making him associate his drone in their banks. Apr 10 21:07:02 loop holes, I presume... Apr 10 21:07:25 Hi. I flashed my newly acquired Beaglebone Black rev C with Debian 9.9. Connecting to my display via HDMI does not work properly (it worked with the original OS). The display receives signal but the screen is black with occasional gleams. I have searched for the issue but seem to find no cases. Is there a know solution? Apr 10 21:07:59 GNUbahn: what image did you flash onto it? Apr 10 21:08:39 zmatt, bone-debian-9.9-lxqt-armhf-2019-08-03-4gb.img Apr 10 21:09:24 oh I think that one doesn't actally fit properly on eMMC, and the lack of free space causes startup failures Apr 10 21:09:52 Yeah, I had some issue with lack of space. Apr 10 21:10:06 You suggest I flash a different image? Apr 10 21:10:21 in general, a graphical desktop environment takes up a lot of space and runs poorly on the BBB, and very few people use it, so generally an image without graphical desktop environment is recommended Apr 10 21:11:28 I see. But I need a graphical DE as I hope to make it into a media center. Is that too ambitious? Apr 10 21:11:41 a beaglebone as media center? that sounds horrible Apr 10 21:12:17 Not really feasible? Apr 10 21:12:19 that doesn't use any of the beaglebone's strengths while simultaneously putting demands on the beaglebone's weakest points Apr 10 21:12:58 Which might mean I have chosen the wrong device then. Apr 10 21:14:13 very much so. the AM335x SoC on the beaglebone is designed for industrial control applications. it has no features for accelerating video en-/decoding, and only the most basic display output facilities (intended e.g. for a simple touchscreen interface) Apr 10 21:16:22 Now this may not be a question for this forum but is a Raspberry Pi better suited for that? Apr 10 21:16:32 i think they make a pi for that in mind Apr 10 21:16:42 i think read somewhere about cheap HTPC Apr 10 21:16:52 do you just want a DVR or something Apr 10 21:17:07 MattB0ne, what is HTPC? Apr 10 21:17:11 i would just get a playstation =D Apr 10 21:17:17 home theater PC Apr 10 21:17:25 GNUbahn: I have zero experience with the rpi, but I vaguely recall that the SoC on it is from a family of SoCs generally used for set-top boxes and other media applications, so I'd assume the rpi is probably better suited for it than the bbb Apr 10 21:17:36 i was looking at it found it not worth the effort Apr 10 21:18:35 zmatt: any reason why i would get a permission denied for opening tty ? Apr 10 21:18:56 this is probably a qt creator thing Apr 10 21:19:13 works fine if I lanuch my program on the board itself Apr 10 21:19:19 The thing is, I wish to make a free software media center. as you may have guessed I have little experience with computers but hoping that the bbb could be used. Apr 10 21:19:32 to store movies? Apr 10 21:19:43 record TV Apr 10 21:19:45 etc... Apr 10 21:20:22 GNUbahn: I've tried to play video on a BBB once and it was basically a slide-show, even at low resolution Apr 10 21:20:32 Actually I just want to play videos from my hard disk (yeah, I know: very old fashioned) and use the internet. Apr 10 21:20:32 I am a noob in embedded systems so take my words with a grain of salt Apr 10 21:20:53 budget? Apr 10 21:21:23 i am guessing low since you grabbed a BBB or do you want the learning experience of building from scratch Apr 10 21:22:37 Money is not the issue. Not that I have loads - I have not - but I just wish to make a simple solution based on free software. For now I use a laptop but would like to spare the space and avoid the fan noise Apr 10 21:23:00 you look into plex Apr 10 21:23:04 ? Apr 10 21:23:11 plex? Apr 10 21:23:48 zmatt, thanks for sharing that experience. Apr 10 21:23:59 https://www.plex.tv/ Apr 10 21:24:32 i used it for a bit before jumping on the tablo train Apr 10 21:26:34 I see. My mission here is primarily to find the hardware to run a media center on. The actual software comes next. I am already running Kodi which more or less suits my needs software-wise. Apr 10 21:29:13 I say do it. Apr 10 21:29:20 W/ the BBB or AI! Apr 10 21:29:33 Let me see if I can find my old book on KODI. Apr 10 21:30:29 set_, you mean do it like try running kodi on the bbb? Apr 10 21:31:17 GNUbahn: I found some performance numbers done on some AM335x-based board (not the BBB), and H.264 decoding at 480x272 pixels (24 fps) was doable (63% cpu load at 720 MHz) but 720x406 pixels at 24 fps was not Apr 10 21:33:54 so if you're fine with 360p24 video then I guess you could give the BBB a try :D Apr 10 21:34:51 I have the XMBC book. I was wrong. Apr 10 21:35:09 I labeled it KODI for some reason. Apr 10 21:35:21 XBMC. sorry. Apr 10 21:37:38 set_, kodi is the new name for xbmc Apr 10 21:38:59 I just noticed. Apr 10 21:39:06 I looked up what happened just now. Apr 10 21:39:12 zmatt, in that case I would have to downgrade all of my videos! I found this book/course on how to turn your bbb into a media center: https://www.packtpub.com/hardware-and-creative/beaglebone-media-center Apr 10 21:39:23 There seems to be no support for the BBB as of now for some reason. Apr 10 21:39:30 PRobably b/c of what @zmatt stated. Apr 10 21:40:24 indeed Apr 10 21:40:27 :D Apr 10 21:40:28 If anyone uses buildroot and wonders why the gpio-of-helper driver doesn’t work: That’s because the device driver is not enabled per default. :D Wish I figured that out sooner… Apr 10 21:41:01 buckket: in fact, when using buildroot you'd probably need to patch your kernel to add support for it Apr 10 21:41:14 zmatt, MattB0ne set_ It seems that I have chosen the wrong path. I will be searching for another solution for my media center AND for other ways to play with my bbb. Thanks for your time. Apr 10 21:41:16 since such basic functionality is inexplicably missing from mainline Apr 10 21:41:32 Okay. Enjoy! Apr 10 21:41:48 BB-AI might be a better start or the beagle X-15 if you want some resolution Apr 10 21:42:09 I mean, for music, okay but video might have some issues. Apr 10 21:42:39 Of course, real time video, my webcam work is way awesome! Apr 10 21:42:40 Boy! Apr 10 21:43:30 You should see the imaging that is gathered via the webcam on my bot from a simple webcam and server. Apr 10 21:43:37 It is awesome w/ the new image. Apr 10 21:43:58 zmatt: So far it seems to work without any patch, using the latest 4.19.94 from github.com/beagleboard/linux Apr 10 21:46:04 of course since that one is already patched Apr 10 21:46:30 GenTooMan: The props are labeled as this Dalprop Cyclone T5050C. Apr 10 21:46:51 pretty sure those are snapshots of the patched kernel trees equivalent to the debian kernels Apr 10 21:47:17 to rcn's beaglebone kernels I mean (the default kernels on the beaglebone debian images) Apr 10 21:47:33 specifically the 4.19-ti series in this case Apr 10 21:53:41 GenTooMan: On this photo, https://ardupilot.org/copter/_images/motororder-quad-x-2d.png, does the number one mean I have to set up a specific motor to that number or can it be any motor that goes CCW? Apr 10 21:55:13 Any of the two CCW motors right? I should be able to have two motors going CCW and two motors going CW. Apr 10 21:55:15 Off to test. Apr 10 22:02:24 set_ go by position notice 1 and 2 are CCW and 3 and 4 are CW Apr 10 22:02:34 GenTooMan: You were right. All four of the motors are CCW now. Apr 10 22:02:41 So, time to solder. Apr 10 22:02:47 Dang it! Apr 10 22:04:14 I will rewire this way ---> take two wires and exchange them for one another on one motor and then apply this idea on the other motor. Apr 10 22:04:47 i get the odd photo. I just could not slow down the props to figure out the dir. of the motors. Apr 10 22:04:55 Now, i got that part down. Yikes! Apr 10 22:05:00 Up, up, and otay!@ Apr 10 22:05:16 you could have used your google drive photo to figure it out Apr 10 22:05:19 :D Apr 10 22:07:21 Ha. I am slow, mate. You know this, man. Apr 10 22:07:24 Sorry. Sir. Apr 10 22:26:51 well just remember when you stop banging your head against the wall it quits hurting Apr 10 22:34:36 I bought a BB Black and the Load Cape. Can somebody where I can find code samples on how to use the Load Cape? Thank you. Apr 10 22:36:12 Lui! Apr 10 22:36:16 I have a load cape. Apr 10 22:36:20 Please wait. Apr 10 22:36:43 I will show you something in a bit. I am soldering something right now. I will be back in a bit. Apr 10 22:39:07 Hi, can anyone help me get a rohs declaration for pn 76Y2810? Apr 10 22:51:08 Lui: Are you still around? Apr 10 22:54:04 The Cape uses GPIO for the pins w/ the srew terminals. Apr 10 22:54:26 So, if you are to make it work, use GPIO typed source. Apr 10 22:54:28 For wiring... Apr 10 22:55:48 https://pastebin.com/0T1QfFqs <<< does this make sense to you? Apr 10 22:57:01 GenTooMan: Okay. Apr 10 22:57:17 I soldered those little buggers together. I burnt my thumb too. Blah. Apr 10 22:58:07 I will keep you updated on if my solder job did its duty Apr 10 23:11:39 the duty is done... Apr 10 23:12:12 The motors are working and now for the grand entrance w/ a couple of prop changes. Ha. Apr 10 23:23:01 Okay. So... Apr 10 23:23:26 Testing is over w/ the drone. It bangs against the inside wall well. Oh and it flies! Apr 10 23:23:59 BBBlue! Apr 10 23:53:13 Yes, I just back to the screen. Give me a sec to read your messges Apr 10 23:54:42 Okay. Apr 10 23:55:30 The pastebin link shows how to connect a DC Motor to the Cape w/ a battery. Apr 10 23:56:20 In the past, I used Adafruit_BBIO as a library for GPIO but I think it may be a library that is not longer viable. I am not sure just yet. I can look that up, too. Apr 10 23:59:32 Thanks a lot, Then, to control the motor, should I use the GPIO signals? Apr 11 00:01:38 Yes. Apr 11 00:01:56 Let me make sure. Please hold. Apr 11 00:03:25 Lui: https://github.com/silver2row/loadcape is something to start w/. Apr 11 00:03:38 I made that a while back but it is working still, I think. Apr 11 00:03:50 I have not tested my loadCape in a bit of time now. Apr 11 00:04:17 I used Adafruit's Library during that stage of source. Apr 11 00:04:39 Yes GPIO. That will work. Apr 11 00:05:47 I can plug it in to test if necessary. Apr 11 00:06:05 Lui: It may take a while for me to set up but I can do it if necessary. Apr 11 00:17:51 Oh and Lui, you need to power the board, BBB or whatever, w/ the barrel jack for use of your loads. Apr 11 00:18:44 yeap. Thank you Apr 11 00:19:02 Even w/ LEDs or other actuators, the barrel jack needs to be plugged in. Apr 11 00:19:04 Okay. Apr 11 01:16:25 GenTooMan: You are not joking. LCD stuff is very complicated. I am just reviewing this book and they have some script for pushing two lines out on a LCD from the BBB. Yikes! Apr 11 01:22:44 set_ well once you can do a line you can do the rest Apr 11 01:28:21 Maybe. I am reading and this book is wowzering me. From the different approaches one can take to the magnitude of the amount of LEDs in one, single unit, there is too much to consume in time. I need to read less so I know less. Ha. Apr 11 01:28:49 I am just reading, Apr 11 01:28:56 "Bad to the Bone." Apr 11 01:29:25 It is simply descriptive and easy to understand but the ideas hitting my mind are boundless. Apr 11 01:32:19 Whats goin on boys? Apr 11 01:33:42 Posted a message to google BBB group https://pastebin.com/Wsx9YXcp Apr 11 01:34:31 Hey KenUnix: I am reading again finally. Apr 11 01:35:22 Check out my posting Apr 11 01:35:35 I saw it. BBBW or BBGW or BBAI? Apr 11 01:35:51 'BBB' brb Apr 11 01:36:10 Why would you bother w/ "hit or miss" source and old drivers when things are being updated/upgraded constantly? Apr 11 01:39:22 I wanted a simple program to display rows and columns for any terminal to make sure the terminal setup matched the stty settings. Here it is https://paste.debian.net/1139646/ Apr 11 01:40:30 Perfboards! Apr 11 01:40:42 I am going to get a perfboard to test things. Apr 11 01:41:15 I went through several upgrades. no difference.;( ;( Apr 11 01:42:00 I remember way, way back getting them from Radio Shack Apr 11 01:42:50 Okay. Apr 11 01:43:00 You are upgrading things, i.e. the image and what else? Apr 11 01:43:18 Phila. had a radio row (electronics) back in the 60's Apr 11 01:43:38 https://elinux.org/Beagleboard:Latest-images-testing Apr 11 01:43:57 And beagleboard.org/latest-images have already put together images for testing. Apr 11 01:44:00 Image , kernel. The works Apr 11 01:44:43 Before World Trade Center NY had a great radio row! Apr 11 01:45:24 When RCA meant something and not just a name Apr 11 01:46:35 Me thinks WiFi never worked well. Apr 11 01:46:54 Oh. It used to says some books but those are old books w/ old drivers in the older kernels. Apr 11 01:47:28 People update things. I guess a start would be to check the current kernel drivers that are available. Apr 11 01:48:04 Then, find a module that works w/ that current driver. Apr 11 01:48:55 It is never that easy, though. Sometimes, source is off or connections are poor. I know those WiFi adapters are power suckers. Apr 11 01:49:29 I stuck one in my linux machine. I touched it. It felt like it was on fire. Apr 11 01:49:30 According to RCN Debian 10.3 has the latest (not always the best)8) 8) Apr 11 01:49:49 Right. Apr 11 01:49:58 The latest but not all of them. Apr 11 01:50:02 Only the ones that made it. Apr 11 01:50:23 For instance... Apr 11 01:50:35 I think the RTL8188EU drivers go way back. Apr 11 01:51:09 If I have a lkm or a already produced driver that was not in the kernel, I would have put the driver in the kernel. Apr 11 01:51:58 For instance, let us take the RTL8188EU. Apr 11 01:52:23 Getting the source is the trick Apr 11 01:52:32 It once worked. It might still work but w/out the proper driver or lkm on your machine, it does not work. Apr 11 01:53:12 So, one can either type up their own and add it to the current image or get one from someone and add it to the current image. Apr 11 01:53:29 It is not C & P from what I understand. Apr 11 01:53:44 It should be OK to look up things like messages Apr 11 01:54:25 I just drank some Strawberry Limeade drink from Tropicana. Apr 11 01:54:32 It is nice and soothing. Apr 11 01:54:47 Since it is Debian I think they call the shots. Apr 11 01:55:00 KenUnix: You can add your own if you know how. Apr 11 01:55:08 Sounds goooood Apr 11 01:55:20 brb Apr 11 01:55:22 I do not. I mean, I have read articles on it but things have changed since then. Apr 11 01:56:19 I would think is any body knows it would be RCN Apr 11 01:57:57 That's why the posting. Do you get daily abbridged summarys daily from Google group? Apr 11 01:58:43 Me, no. Apr 11 01:59:06 I get ideas only when I am involved. Apr 11 01:59:08 I think. Apr 11 01:59:18 Why not. It's a nice list of what's happening Apr 11 01:59:22 I am not sure exactly. Apr 11 01:59:40 It must have set me up for the basics? Apr 11 01:59:44 Hmm. I have no clue. Apr 11 02:02:08 I am on Chapter 5 and reading about the SeaPerch! Apr 11 02:03:18 If you want so see software stuff link to this https://groups.google.com/forum/#!categories/beagleboard/support/newbies/beaglebone-black/software/debian Apr 11 02:05:00 I am going to try to build something w/ the BBB or related board! I have not done it yet on my own but it shall be done and done well (one day). Right now, I am just learning w/out acting (hopefully). Apr 11 02:06:09 mm hmm :D Apr 11 02:06:22 If interested in everything link this https://groups.google.com/forum/#!categories/beagleboard/support/newbies/beaglebone-black Apr 11 02:06:37 Hi GenTooMan Apr 11 02:09:20 Why would someone want to install FreeBSD on BBB? Apr 11 02:12:56 FreeBSD is too retro Apr 11 02:18:26 Man...this SeaPerch thing is nifty. I never would have thought to use a bilge pump for underwater propulsion. Apr 11 02:19:11 Almost, it is like a octopus scooting away w/ bursting. Apr 11 02:21:43 and this is overboard. A Jones connector. Nice! Apr 11 02:25:14 You know because of the coronvirus and less travel air quality is up and smog is down... Apr 11 02:33:19 Breathe freely. Apr 11 02:37:43 Good night Apr 11 02:38:42 Who built the Mountain Maze from that book I have been reading? Apr 11 02:38:50 That is cooler than neat. Apr 11 02:41:12 I saw the photo of all that bondo. I went bonkers! Apr 11 02:44:32 some people are use to using Freebsd kenunix Apr 11 02:46:58 someone commented that when they were driving through NYC. **** ENDING LOGGING AT Sat Apr 11 02:59:57 2020
