**** BEGIN LOGGING AT Sat Jun 17 03:00:02 2017 Jun 17 19:03:20 Hi All, Had anyone experienced working with UniFlash for BBB flashing? Jun 17 19:44:08 Hi All, Had anyone experienced working with UniFlash for BBB flashing? Jun 18 00:18:15 Okay...I am back and boring as ever. Jun 18 00:18:36 What are people reading these days in regards to the BBB and variants? Jun 18 00:19:14 to know about the differences you mean? Jun 18 00:19:32 No...just in general. Jun 18 00:20:58 I'm reading this channel? sometimes anyway Jun 18 00:21:19 and the schematics of newer variants, if I care to know what they're about and how they differ from the BBB Jun 18 00:22:03 I have a couple of books and some references from online sources. I really NEED/WANT some type of reference on programming in the Linux environment with embedded in mind. Jun 18 00:22:04 ... Jun 18 00:22:09 Do you recommend anything? Jun 18 00:22:25 I don't think I'm the right person to ask Jun 18 00:22:31 Why not? Jun 18 00:22:44 What is wrong with you? Jun 18 00:23:09 because I'm pretty sure I've never read (or looked for) something resembling what you're describing Jun 18 00:23:24 Oh...no problem. I will keep searching. Jun 18 00:23:33 it sounds oddly specific though Jun 18 00:23:40 and yet too generic Jun 18 00:24:02 I pick up books every now and then. I read them and leave myself guessing. Jun 18 00:24:16 linux userspace programming is mostly the same on embedded, desktop, and server Jun 18 00:24:30 heh? That is great news. Jun 18 00:24:53 zmatt: There is something I am missing when I program items. Jun 18 00:25:27 For instance...I program the BBB/BBG/BBBlue and so on. I use books and ideas from the opensource world. Jun 18 00:26:07 I do not try what I have learned because there is always something that needs tending to. Jun 18 00:26:21 I have absolutely no idea what you're trying to say Jun 18 00:26:29 Tending to = some syntax error or something. Jun 18 00:26:52 then fix your typos and try again Jun 18 00:26:56 Where can I look up syntax errors when applying software to the BBB? Jun 18 00:26:58 Ha! Jun 18 00:27:06 nowhere, since that makes no sense Jun 18 00:27:21 See...there is something I am missing. Jun 18 00:27:38 a compiler or interpreter isn't suddenly going to accept different syntax because you run it on a different architecture Jun 18 00:29:07 Augh. So, for instance, what I learn in Python actually works on our BBB/Linux environment if the syntax is correct? Jun 18 00:29:27 ehm, what? Jun 18 00:29:37 See sir...I am missing something. Jun 18 00:29:40 python understands... (ta-da) Python! Jun 18 00:29:57 just be mindful if you're using python 2 or pythong 3 Jun 18 00:30:01 *python 3 Jun 18 00:30:07 Right...it understands what I tell it as long as it understands. Jun 18 00:30:50 if you get a syntax error on the BBB, you'll get a syntax error on every other system too Jun 18 00:30:58 it's just python Jun 18 00:31:24 it's just python, running on just a linux system Jun 18 00:32:38 Oh...okay. So, let us say, I am off to look up syntax errors in Python. Where would I start? For instance, I have been working with JavaScript too. I want to find an error and I have no idea where to start. What books are available for reading about error info? Jun 18 00:32:39 ... Jun 18 00:32:45 Sorry for all this typing. Jun 18 00:32:58 any python tutorial or javascript tutorial respectively Jun 18 00:33:03 I'm sure the internet has plenty of both Jun 18 00:33:14 at least, if they're *syntax* errors Jun 18 00:34:11 You are right. The Internet has both. If I was to receive other errors, including syntax errors, what books are available to make me understand why it is that I keep running into specific errors? Jun 18 00:34:15 of course if you're using python modules or nodejs modules that provide BBB-specific functionality, and have problems with those, *then* .... figure out who made the module and complain to them :P Jun 18 00:34:26 Oh. Jun 18 00:34:28 Okay. Jun 18 00:34:40 but a syntax error is not a problem with a module Jun 18 00:34:43 it's a syntax error Jun 18 00:35:10 it means that python's or javascript's code looked upon your code, and thought "wha?" Jun 18 00:35:25 :) Jun 18 00:35:34 So, a module is a listed "phrase" for my code that has bindings? Jun 18 00:35:51 i.e. to C++ or C. Jun 18 00:35:52 ? Jun 18 00:36:24 a module is a chunk of code (e.g. python or javascript) that you can use Jun 18 00:37:24 and yeah it's also possible to write python modules in C or nodejs modules in C++ ... generally though when using a module you don't need to care how it was implemented Jun 18 00:37:43 Oh. Jun 18 00:38:43 Like the Motor Bridge Cape: it has the .py software to call in a library, e.g. import MotorBridge. Jun 18 00:39:05 which imports some library they presumably also provided Jun 18 00:39:14 (library, module, whatever) Jun 18 00:39:50 Yes Sir. They provided it. This library/module works. I have used it and set up a couple of different software options. Jun 18 00:40:08 I can make a big chunk of metal do some things. Jun 18 00:40:13 hurray Jun 18 00:40:20 Heh! Jun 18 00:41:01 So, there are no people on GitHub.com that use this software for some reason or they do not admit to it. Jun 18 00:41:24 ? Jun 18 00:41:36 Either/or...I do not care. I just care enough to make this Cape work for me and my needs. Jun 18 00:42:01 I see an outstanding pull request even, and an open issue... so evidently people are using it Jun 18 00:42:23 Does the BBB.io 'org have any ideas for motor control that...wha? I must have been looking in the wrong section. Jun 18 00:42:30 ? Jun 18 00:42:47 I'm just referring to the github page of the MotorBridgeCape Jun 18 00:42:53 you said no people on github used it Jun 18 00:43:00 Serious. I starred it. Jun 18 00:43:34 I thought people admitted to their interest more than is reality. Jun 18 00:43:41 most people who use it will just download/clone it... there's no way to tell how many people have done that Jun 18 00:44:13 My issue. Moving on. Oh and you are right. I just thought people would work together more on it, i.e. with the software and hardware aspects. Jun 18 00:46:24 there, I think I closed the open issue :P Jun 18 00:46:39 (well, I can't actually close it as such, but you know what I mean) Jun 18 00:47:14 zmatt: I have a real interesting theory that probably has been done over and over again. Jun 18 00:47:20 but yeah, it seems poorly maintained Jun 18 00:47:35 considering the "open issue" was completely trivial to address Jun 18 00:48:16 but in general I don't get a particularly good impression from seeed Jun 18 00:48:32 I tried to get a good impression and I have been let down at times. Jun 18 00:49:11 They have helped some but their site for the Hub is kind of lacking. People do not go and post there much. Jun 18 00:49:39 I try to help out at times and I keep getting no replies. Jun 18 00:50:28 For instance, one person asked about stacking Capes. I wondered if he knew about the issue with stacking. Jun 18 00:51:38 Open pins were what I brought up. I thought if this fellow/gal knew about if the pins were being used or not, he/she could then move on from there. Jun 18 00:52:02 It has been weeks. No reply yet. Jun 18 00:52:32 I do like their Wikis. They have some, although sometimes short, useful info. Jun 18 00:52:54 ... Jun 18 00:54:05 zmatt: I was bringing up all that garbage talk to discuss something with someone. I am glad you have arrived and I like that you keep chatting. So... Jun 18 00:54:34 I don't understand stuff like this: https://pastebin.com/raw/8jxnD0kM Jun 18 00:54:52 and then he sat around for a while without saying anything and then left Jun 18 00:55:55 oh well, *shrug* Jun 18 00:56:24 So, people just sit and wait. Jun 18 00:57:02 They are looking for the next thing to prey on maybe or they could be like you and I, i.e. people that only know so much about specific subjects. Jun 18 00:57:41 I understand from chatting w/ you that you are better prepared to handle Linux, the BBB, and items of those subjects. Jun 18 00:58:16 well...in comparison to me. Jun 18 00:58:43 I only know specific methods and most of what you say is better than what I say. Jun 18 00:58:57 the point was that he just repeated his question as if nothing had happened Jun 18 00:59:07 I have a long, drawn out way. You can pinpoint the situation. Jun 18 00:59:08 Oh. Jun 18 00:59:33 Maybe that person just wanted your info. Jun 18 00:59:50 ? Jun 18 01:00:06 i.e. what yoy know. Like, maybe that person just wanted answers. Jun 18 01:00:16 yoy = you Jun 18 01:00:26 which I had given him the day before Jun 18 01:00:42 People have terrible memories, unlike the BBB. Jun 18 01:00:53 Who knows? I have no clue who that person is. Jun 18 01:01:17 me neither, it's just one of many people I just don't understand Jun 18 01:02:04 Heh, "it takes all kinds." Not only do people around Linux and the BBB act oddly, they also may never meet. Jun 18 01:02:08 (even more puzzling: https://pastebin.com/raw/kgLAHHpK ) Jun 18 01:02:46 (left again without saying more of course) Jun 18 01:03:11 Who are all these people sitting around never saying anything? Jun 18 01:03:28 I see a list of people >>>>>>> Jun 18 01:03:29 just people Jun 18 01:03:32 Oh. Jun 18 01:03:37 and probably a few bots Jun 18 01:03:40 Bots? Jun 18 01:03:52 I think those things like to post repeatedly. Jun 18 01:03:59 So I thought. Jun 18 01:04:09 you have as many sorts of bots as there are automated tasks to be performed Jun 18 01:04:16 logging for example Jun 18 01:04:26 Yea? Jun 18 01:04:41 You have all that covered? Jun 18 01:04:47 ? Jun 18 01:05:08 So, somehow you can remember for later what has taken place. Jun 18 01:05:47 That is something I never got about computers. What in the world would it be if things were just erased for good. Jun 18 01:05:55 ? Jun 18 01:05:59 oh, my irc client logs too, but I meant there are one or more bots whose purpose here will be solely to log the chat, for public archives Jun 18 01:06:10 Oh. Jun 18 01:06:14 Ut oh. Jun 18 01:06:23 I better sound dumber than expected. Jun 18 01:07:04 Hey zmatt: who would pay or want to review that info. about this client? Jun 18 01:07:22 Hint, hint? Jun 18 01:07:24 The man? Jun 18 01:07:27 Ha! Jun 18 01:07:51 (the official logs seem to be broken at the moment though -> https://beagleboard.org/static/irclog/ ) Jun 18 01:07:55 uhh, what? Jun 18 01:08:02 Nothing. I joke at times. Jun 18 01:08:05 I so often have no idea what you're saying Jun 18 01:08:22 I understand. People do not "get me." Jun 18 01:12:39 Okay. So. Can I use the BBB to run a small power utility? Jun 18 01:13:25 For instance, I want my mower to be able to charge the battery when it runs down. This would be all on the same piece of metal frame. Jun 18 01:17:17 see "I so often have no idea what you're saying" Jun 18 01:17:21 but I'm off anyway Jun 18 01:17:44 BBG > Motor Bridge Cape > DC Motor > Battery / Solar Power > Battery > DC Motor? Jun 18 01:17:47 Okay... Jun 18 01:17:53 zmatt: see you later. Jun 18 01:18:39 I would use a chain to drive the DC Motor back into the Battery when it runs down, i.e. the first battery. Jun 18 01:20:12 I will be around if anyone knows what I am discussing. Jun 18 01:24:34 "regenerative breaking" Jun 18 01:24:41 Maybe. Jun 18 01:25:08 or just "power generation" ... Jun 18 01:25:25 This is what I wanted to learn about with my BBB. I tried some robots and grew into wanting to do this. Jun 18 01:25:42 (I'm half-off btw :P ... off-ish ...) Jun 18 01:25:49 Okay...no issue. Jun 18 01:26:25 zmatt: If you know of a book that encompasses aspects to this idea. I may want to pick one up. Jun 18 01:26:56 I will keep up the research and idea making. Jun 18 01:34:38 Oh and thank you. Jun 18 02:18:08 Regenerative braking is only when my motor would produce a brake in function when on certain slopes/inclines which in turn would stop the heat from escaping my battery. Jun 18 02:20:38 I am thinking of something different I guess. My BBB needs to control the mechanical function of a DC Motor to produce a refueling of battery supply via light/solar power. Jun 18 02:23:37 How can I produce my BBB to make it known when my solar power is ready to be discharged into my battery? Jun 18 02:24:09 I think that is the question that will start where I am headed. Jun 18 02:29:30 For instance... Jun 18 02:36:17 I am sure it is just a software to hardware fix but connections are my downfall. **** ENDING LOGGING AT Sun Jun 18 03:00:01 2017
