**** BEGIN LOGGING AT Mon Feb 17 02:59:57 2020
Feb 17 03:10:50 <GenTooMan> or an atari st too
Feb 17 03:26:13 <set_> debounce your switches!
Feb 17 03:48:33 <GenTooMan> I think the more difficult thing is formatted decimal code. I've don't half and single precision formatted output.
Feb 17 03:52:39 <set_> GenTooMan: How do you do half precision formatting?
Feb 17 03:54:41 <set_> I just looked it up. That seems terribly long winded.
Feb 17 03:55:40 <set_> binary16?
Feb 17 04:10:31 <set_> Well, I was reading more and now, "I absolutely know nothing more than when I started." I hope you are happy.
Feb 17 04:11:17 <set_> Something about 16 bits (2 Bytes), a exponent, and something called mantissa?
Feb 17 04:11:31 <set_> Man, talk about, talk about.
Feb 17 04:17:13 <set_> I see 754-2008 has been extinct for a bit. Look here: https://standards.ieee.org/standard/754-2019.html. It seems a person from LUSfiber holds the rights w/ another person.
Feb 17 04:17:33 <set_> It costs money, no!
Feb 17 04:21:12 <GenTooMan> Yes.. 10 bits mantissa wand 6 bits exponent. Doable but not easy.
Feb 17 04:22:07 <GenTooMan> Why bother just look up the info on wikipedia. It's not hard to do that much. the tough part comes from converting the mantissa into decimal numbers.
Feb 17 04:22:31 <GenTooMan> There are entire papers on how to do it.
Feb 17 04:24:35 <GenTooMan> Anyhow I did that for one job I was doing. I also had to make accurate routines to convert from single to half and back again.
Feb 17 04:24:48 <set_> No!
Feb 17 04:25:11 <GenTooMan> So half precision has 3 digits single has 6.5 digits and double has a LOT :D
Feb 17 04:25:34 <set_> Oh.
Feb 17 04:25:35 <set_> Okay.
Feb 17 04:25:59 <set_> What were you configuring? I mean, were you handling graphic chips?
Feb 17 04:28:01 <GenTooMan> No I had an embeded system and the 'printf' code used up like 7k of space. So I made a single precision decimal format code that used 1.5k. Then I had to store 1000's of readings into a log so I had to compress single precision values into half precision.
Feb 17 04:29:07 <set_> Oh.
Feb 17 04:29:24 <set_> I am not sure what that entails but I think you decribed it well enough.
Feb 17 04:30:10 <GenTooMan> well getting the code to print out and format correctly isn't as easy as one would like or think.
Feb 17 04:30:23 <set_> So, you had to have some program from your doing tally numbers, compress the tally, and then came the binary16 MATH "LOVE."
Feb 17 04:31:35 <set_> I know from looking at wikipedia, that math is not easy. It has no real, defined logic in my mind. As of now.
Feb 17 04:33:28 <GenTooMan> I wrote a paper up on it at work but my boss was really LAZY and didn't care. <-- typical "non manager"
Feb 17 04:34:21 <set_> Aw.
Feb 17 04:34:39 <set_> Yea. Sometimes it is worth getting fired over. I know. Now, I am no one in no one land.
Feb 17 04:35:13 <set_> GenTooMan: Sometimes work ethic is about not caring.
Feb 17 04:35:33 <set_> "Mike did good, who cares?" "I do nothing and it is fine too."
Feb 17 04:36:06 <set_> That reminds me of Python3 and the BBBW.
Feb 17 04:36:50 <set_> if b == no one cares or c == I do nothing:
Feb 17 04:36:53 <set_> pass
Feb 17 04:37:25 <GenTooMan> Anyhow their are several papers regarding it between 2003-2015 apparently it's not "resolved" professional libraries do not have the same precision
Feb 17 04:38:06 <set_> Just for reference, I spoke up enough to know my place in life. I am outside Joe for now. Boo but worth every damn second.
Feb 17 04:38:27 <set_> Oh.
Feb 17 04:38:37 <GenTooMan> If you want to print hex digits that shouldn't be hard at all.
Feb 17 04:38:56 <GenTooMan> You just have to think backwards :D
Feb 17 04:39:04 <set_> No, it is not. I found the python console to work at times.
Feb 17 04:39:49 <set_> But...the articles on hex printing is not valid w/ python3 or something. It says it should work.
Feb 17 04:40:47 <set_> I just know more now than when I started. This is good news for me. I can start to apply what I learned.
Feb 17 04:42:43 <set_> https://www.programiz.com/python-programming/methods/built-in/hex is something I can try next. See, I am already starting to learn how to compute better results in my searches.
Feb 17 04:43:38 <set_> hex()?
Feb 17 04:43:40 <set_> Hmmm.
Feb 17 04:50:09 <RakeshBabu> Hello
Feb 17 04:50:31 <set_> I am learning too!
Feb 17 04:50:35 <set_> Hello.
Feb 17 04:50:43 <RakeshBabu> i am newbie to the beaglebone technology
Feb 17 04:50:57 <RakeshBabu> can anyone help me out.
Feb 17 04:51:00 <set_> Me too. What do you need to know?
Feb 17 04:51:27 <set_> RakeshBabu: Do you need to put a new image on your board?
Feb 17 04:51:42 <RakeshBabu> 1)what is this used for and how to use this.
Feb 17 04:52:10 <RakeshBabu> 2) how is this different from other boards like; raspberry pi etc.
Feb 17 04:52:14 <set_> Robots, Sensors/Actuators, i2c communication, and other stuff.
Feb 17 04:52:32 <set_> You can do a lot w/ this board.
Feb 17 04:52:57 <RakeshBabu> can i find any tutorials for this technology.
Feb 17 04:53:02 <set_> Yep!
Feb 17 04:53:12 <RakeshBabu> where can i find?
Feb 17 04:53:14 <set_> Oh.
Feb 17 04:53:20 <set_> Look at this site bbb.io
Feb 17 04:53:31 <set_> That is their main page.
Feb 17 04:54:09 <RakeshBabu> what is the difference between beagleboard and beaglebone ai.
Feb 17 04:54:35 <set_> Oh. BBB has the am335x and the AI has the am5729.
Feb 17 04:54:42 <set_> Those are the chips.
Feb 17 04:55:00 <set_> Oh and...
Feb 17 04:55:33 <RakeshBabu> how can i use this beaglebone ai for data transferring i.e. files, audio, video etc.
Feb 17 04:55:47 <set_> Hmm. Linux.
Feb 17 04:56:08 <set_> You can use Linux to transfer data.
Feb 17 04:56:58 <set_> scp!
Feb 17 04:57:09 <RakeshBabu> how to connect this and how can i send the data to another device.
Feb 17 04:57:35 <set_> Plug in the usb. Sign in. Then, use scp.
Feb 17 04:58:10 <set_> You might have to install scp. I am not sure exactly. I can test it.
Feb 17 04:58:19 <RakeshBabu> should i connect the ai board to my laptop.
Feb 17 04:58:31 <set_> Sure. You can do that. Do you have a fan?
Feb 17 04:58:47 <RakeshBabu> what is that?
Feb 17 04:59:10 <set_> Fan? Oh, it is a oscilating device that spins.
Feb 17 04:59:29 <set_> Fan...you know.
Feb 17 04:59:31 <RakeshBabu> i am in 12th standard. i do not know much about this
Feb 17 04:59:53 <set_> Okay but you know how to program.
Feb 17 04:59:56 <set_> Right/
Feb 17 04:59:57 <set_> ?
Feb 17 05:00:01 <RakeshBabu> yeah i know.
Feb 17 05:00:11 <set_> See, you are good w/ something!
Feb 17 05:00:15 <set_> Okay.
Feb 17 05:00:19 <set_> So, do you have a fan?
Feb 17 05:01:07 <RakeshBabu> can i send files anywhere using it or it is having any limitations?
Feb 17 05:01:35 <set_> Oh. If you make something w/ it, I am sure you can send all types of files w/ smtp and google's gmail.
Feb 17 05:01:49 <set_> Or whatever mail client you use.
Feb 17 05:02:18 <RakeshBabu> through mail?
Feb 17 05:02:22 <set_> Yep.
Feb 17 05:02:37 <set_> gmail!
Feb 17 05:03:07 <RakeshBabu> can you give the glimpse about it. how to use it and i am using C programming for this.
Feb 17 05:03:25 <set_> Oh.
Feb 17 05:03:27 <set_> Okay.
Feb 17 05:03:30 <set_> Hey.
Feb 17 05:03:40 <set_> Did you plug in your device yet?
Feb 17 05:03:47 <set_> w/ fan attached?
Feb 17 05:04:08 <RakeshBabu> fan is used to cool the device
Feb 17 05:04:12 <set_> USB fans work too. Right!
Feb 17 05:04:27 <RakeshBabu> yeah device is working fine.
Feb 17 05:04:41 <set_> Yep. I found it keeps the processor cooler if the fan runs continuously.
Feb 17 05:04:55 <set_> Nice.
Feb 17 05:04:57 <set_> Okay.
Feb 17 05:05:07 <set_> So...what is the issue?
Feb 17 05:05:39 <RakeshBabu> i want to know that ai is usb device or uart or spi etc.
Feb 17 05:06:14 <set_> Hmm. I am pretty sure I cannot understand yet what you are asking.
Feb 17 05:06:16 <set_> I am sorry.
Feb 17 05:06:33 <set_> USB C to USB 3.0?
Feb 17 05:06:56 <RakeshBabu> do you know about USB UART I2C SPI communication protocols
Feb 17 05:07:18 <set_> Oh. Sort of. Not really. I mean, I read about them from time to time.
Feb 17 05:07:33 <set_> I use them in communication at times w/ the BBB.
Feb 17 05:08:09 <RakeshBabu> what coummunication protocol is used by beaglebone ai? USB UART SPI
Feb 17 05:08:23 <set_> Oh. Good Question!
Feb 17 05:08:54 <RakeshBabu> thank you. can you please elaborate that.
Feb 17 05:08:57 <set_> all of the above, mostly. There are some that the am5729 cannot handle b/c of the set up onboard the BBAI.
Feb 17 05:09:46 <set_> Only so many peripherals are available on the AI but you have choices, i.e. more than just GPIO, i2c, SPI, and UART.
Feb 17 05:09:46 <RakeshBabu> how to connect it and use
Feb 17 05:10:11 <set_> There are some other types of chips available onboard too.
Feb 17 05:10:43 <set_> Right. There is DSPs, EVEs, and some PRUs.
Feb 17 05:11:06 <set_> RakeshBabu: How would you like to use it?
Feb 17 05:11:23 <set_> You mean, like to make things happen? Communicate to another device?
Feb 17 05:11:31 <RakeshBabu> that means i want to learn more about this.
Feb 17 05:11:41 <set_> Okay.
Feb 17 05:11:52 <set_> Well, I can be quiet and maybe another person will come in.
Feb 17 05:11:56 <set_> Sorry to bother you.
Feb 17 05:12:00 <RakeshBabu> i need to use this for data transferring i.e. send audio files,
Feb 17 05:12:06 <set_> scp!
Feb 17 05:12:09 <set_> Use scp.
Feb 17 05:12:12 <RakeshBabu> yeah.
Feb 17 05:12:20 <set_> Are you on Linux or Win?
Feb 17 05:12:36 <RakeshBabu> i am using linux
Feb 17 05:12:39 <set_> Nice!
Feb 17 05:12:40 <set_> Okay.
Feb 17 05:12:51 <RakeshBabu> how to get started with.
Feb 17 05:13:05 <RakeshBabu> what programming language you are using
Feb 17 05:13:11 <set_> Use scp. Here: https://www.linuxtechi.com/scp-command-examples-in-linux/.
Feb 17 05:13:34 <set_> Oh me. I am just learning about programming (very slowly as some would point out).
Feb 17 05:13:55 <set_> Python, Um.
Feb 17 05:14:16 <RakeshBabu> ok.
Feb 17 05:14:20 <set_> I use node.js at times w/ that bonescript language that one of the founders made.
Feb 17 05:14:48 <set_> Sometimes, I use other languages but I am only one person.
Feb 17 05:14:59 <set_> It takes a lot of energy to learn new languages.
Feb 17 05:15:01 <RakeshBabu> good.
Feb 17 05:15:10 <RakeshBabu> yeah.
Feb 17 05:15:21 <RakeshBabu> i have a question for you.
Feb 17 05:15:27 <set_> RakeshBabu: Shoot!
Feb 17 05:16:03 <RakeshBabu> i am connecting the beagle bone to LAN network.
Feb 17 05:16:17 <set_> Okay. W/ Internet?
Feb 17 05:16:39 <RakeshBabu> using intranet.
Feb 17 05:16:48 <set_> Oh.
Feb 17 05:16:49 <set_> Okay.
Feb 17 05:17:01 <set_> It has been sometime since internet has been used.
Feb 17 05:17:08 <set_> I meant intranet.
Feb 17 05:17:19 <RakeshBabu> i am creating a loop for the beaglebone ai.
Feb 17 05:17:25 <set_> Nice.
Feb 17 05:17:54 <set_> So, this loop will send multiple file transmissions in time?
Feb 17 05:18:02 <RakeshBabu> did you get know what i meant by loop.
Feb 17 05:18:24 <set_> Yea. While, for do, etc...
Feb 17 05:18:35 <RakeshBabu> i will send the file and file is received by the same device.
Feb 17 05:18:56 <set_> Okay. Yikes. You mean, you need an entire mail server on your BBAI?
Feb 17 05:19:30 <set_> You might need to find a small, very small, client.
Feb 17 05:19:42 <RakeshBabu> i am not using mail server.
Feb 17 05:19:49 <set_> Okay.
Feb 17 05:20:25 <RakeshBabu> writing two programs using file handling and system calls.
Feb 17 05:20:30 <set_> Okay.
Feb 17 05:20:43 <set_> That is okay. So, what is the issue w/ making this file?
Feb 17 05:21:25 <RakeshBabu> i want to receive the same data in receiving side.
Feb 17 05:21:41 <set_> So, you send the data and receive a copy?
Feb 17 05:21:57 <set_> Make a copy.
Feb 17 05:22:03 <RakeshBabu> correct
Feb 17 05:22:24 <set_> So, you need to know how to set up a copy in .c format?
Feb 17 05:22:37 <RakeshBabu> yes.
Feb 17 05:22:40 <set_> Oh.
Feb 17 05:22:52 <set_> Um, wait for help. I am terrible w/ .c programming.
Feb 17 05:23:08 <set_> All those directives and Makefiles.
Feb 17 05:23:13 <set_> Yikes! They scare me.
Feb 17 05:23:17 <RakeshBabu> how to send the data to beagle and how to compile the programs.
Feb 17 05:23:37 <set_> Oh. Like any other linux device.
Feb 17 05:24:02 <set_> I mean. you use gcc for .c and g++ for c++ to compile, right?
Feb 17 05:24:10 <RakeshBabu> yes
Feb 17 05:24:13 <set_> Okay.
Feb 17 05:24:16 <set_> So...
Feb 17 05:24:19 <set_> Use 'em.
Feb 17 05:24:25 <set_> At least try first.
Feb 17 05:24:36 <RakeshBabu> those were not working for these
Feb 17 05:24:41 <set_> What is the error?
Feb 17 05:25:06 <set_> Oh. Install them w/ internet. sudo apt install gcc g++
Feb 17 05:26:06 <set_> If you have gcc or g++, you need to download the files to your BBAI somehow, right. But, you need to correct versions that work w/ the BBAI.
Feb 17 05:27:10 <set_> I do not know currently what versions are available on the BBAI but come back tomorrow. set_ is my name. I can help w/ that idea if you need help still w/ porting the gcc/g++ versions you need.
Feb 17 05:27:24 <RakeshBabu> last  question
Feb 17 05:28:06 <set_> Okay.
Feb 17 05:28:06 <RakeshBabu> arent you there
Feb 17 05:28:15 <set_> I guess. I am here.
Feb 17 05:28:40 <RakeshBabu> after using ssh command. i am able to acces the beaglebone.
Feb 17 05:29:20 <RakeshBabu> i want to downlaod some libraries for beaglebone to know the statistics at what speed the data is fetching.
Feb 17 05:29:36 <RakeshBabu> how to install the driver libraries in beaglebone.
Feb 17 05:29:55 <RakeshBabu> may i klnow the command for it.
Feb 17 05:30:46 <set_> Sure.
Feb 17 05:30:58 <set_> sudo apt update && sudo apt upgrade
Feb 17 05:31:24 <RakeshBabu> thank you.
Feb 17 05:31:31 <set_> You are welcome.
Feb 17 05:31:34 <RakeshBabu> are they working on your system.
Feb 17 05:31:38 <set_> Yep!
Feb 17 05:32:19 <RakeshBabu> thanks for sharing.
Feb 17 05:32:25 <set_> You are welcome.
Feb 17 05:32:27 <set_> Have fun!
Feb 17 05:33:14 <RakeshBabu> i will get to you if i had any doubts.
Feb 17 05:33:37 <RakeshBabu> :] :] :]
Feb 17 05:33:40 <RakeshBabu> byee
Feb 17 05:38:30 <set_> I won!
Feb 17 05:38:33 <set_> I won it all.
Feb 17 05:38:47 <set_> Learn well, Godspeed.
Feb 17 05:38:51 <set_> bbl
Feb 17 14:29:28 <Linus_SWE> Hi! Im having some problem when building my own debian distro for the BBB. The problem is that I cant get the power button to shutdown the BBB. Im not sure but I think its related to not having any /dev/input but Im not sure. Any ideas? How to I get stuff at /dev/input?
Feb 17 14:29:50 <zmatt> Linus_SWE: which kernel are you using?
Feb 17 14:30:25 <Linus_SWE> 4.19.90
Feb 17 14:30:29 <Linus_SWE> TIs
Feb 17 14:31:17 <zmatt> as in, rcn's 4.19-ti series or literally from TI's kernel repository?
Feb 17 14:32:02 <Linus_SWE> Its from TI's kernel repository.
Feb 17 14:32:38 <zmatt> any specific reason to not use rcn's kernel packages, like the default debian images for beaglebone use?
Feb 17 14:34:10 <Linus_SWE> We are designing a custom board (based on the AM3352) for a customer. Im doing some work on a Beaglebone before that custom card is ready.
Feb 17 14:35:29 <zmatt> okay, and? :)
Feb 17 14:35:37 <Linus_SWE> True ;)
Feb 17 14:36:14 <zmatt> if something like this is working differently on your kernel versus the default one, the obvious thing to look into would be whether any patches in rcn's kernels might be responsible for that
Feb 17 14:36:51 <zmatt> drivers/input/misc/tps65218-pwrbutton.c   is the driver responsible
Feb 17 14:36:59 <Linus_SWE> Godd idea, Ill go and have a look. Thanks!
Feb 17 14:39:45 <zmatt> lol wtf.... https://github.com/RobertCNelson/ti-linux-kernel-dev/blob/ti-linux-4.19.y/patches/drivers/tps65217/0001-HACK-tps65217_pwr_but.patch
Feb 17 14:40:04 <zmatt> I wonder what the story behind that is
Feb 17 14:41:04 <Linus_SWE> lol :)
Feb 17 14:41:35 <zmatt> that's the repository to use btw if you want to build a customized version of rcn's -ti kernel series
Feb 17 14:41:52 <zmatt> some further notes on that: https://pastebin.com/eLhrp1Hg
Feb 17 14:43:02 <Linus_SWE> Thanks!
Feb 17 16:04:33 <kremlin> m
Feb 17 16:37:41 <GenTooMan> m krem
Feb 17 21:22:44 <GenTooMan> hmmm I wonder if that is the results of splits
Feb 17 22:41:03 <set_> GenTooMan: Hey!
Feb 17 22:47:48 <set_> Anymore binary16 for you since yesterday?
Feb 18 01:02:12 <GenTooMan> ummm no ... I suppose I should write the code back up and put it on github. That way it's mine. The fun part would be testing it.  Last time it required 10E5 printfs using my code vs comercial and then verify the differences were correct on mine.
Feb 18 01:06:16 <set_> Aw. Yea. I might not do that at all. Sounds like a mess of work. Like momma always says, "BE LAZY, $#%& for brains."
Feb 18 01:06:41 <set_> wsl is working well now on Win. I wonder what I can accomplish now?
Feb 18 01:06:42 <set_> Hmm.
Feb 18 01:07:35 <GenTooMan> wsl?
Feb 18 01:07:59 <set_> I wonder if I can compile on it. Hold for the meaning.
Feb 18 01:08:29 <set_> Windows Subsystem for Linux.
Feb 18 01:08:41 <set_> I can use Debian and Ubuntu so far.
Feb 18 01:09:01 <set_> I am trying what veremitz told me to learn.
Feb 18 01:09:20 <set_> So, I am going to plug in that AVR chip to a programmer I build and learn from scratch. I need to learn more.
Feb 18 01:09:37 <set_> I know so little. It is embarrassing.
Feb 18 01:27:17 <GenTooMan> set_ you are way ahead of most people already, most people don't realize they know little :D
Feb 18 01:33:42 <GenTooMan> as for programming the AVR you have a terminal program for windows? If so you can experiment by sending hello world from the AVR to the serial port to get serial communications working. It is useful to learn communication with the micro controller.
Feb 18 02:00:00 <zmatt> set_: AVR programming? but why?
Feb 18 02:11:59 <set_> Ha.
Feb 18 02:12:35 <zmatt> tired of the luxury of the am335x, so you've decided to fiddle with annoying limited 8-bit microcontrollers?
Feb 18 02:12:53 <set_> @zmatt: it is a smaller chip. I thought i could do less w/ less.
Feb 18 02:12:54 <set_> Ha.
Feb 18 02:13:26 <set_> I am just going to try b/c setting up a USBtinyISP might be simpler on it.
Feb 18 02:13:48 <zmatt> it's indeed a smaller chip, which generally means most things will be more difficult due to the more limited resources
Feb 18 02:14:00 <set_> Oh.
Feb 18 02:14:12 <set_> I mean, I am not switching so to say. I just thought I would give it a go.
Feb 18 02:14:34 <zmatt> like, I'd rather be programming PRU than an 8-bit micro
Feb 18 02:15:11 <set_> Oh. I just figured I could learn about bin, dec, hex, oct, and so on w/ that chip a bit easier.
Feb 18 02:15:16 <zmatt> no?
Feb 18 02:15:21 <set_> Oh?
Feb 18 02:15:27 <zmatt> that doesn't even make any sense
Feb 18 02:15:32 <set_> Okay.
Feb 18 02:16:24 <zmatt> understanding different number systems needs no hardware of any kind, just some explanation and maybe a calculator that can switch between them
Feb 18 02:16:59 <set_> Right. I get that idea. But, referencing chips selected by BBB.io persons is difficult for me as you can tell.
Feb 18 02:17:08 <zmatt> ?
Feb 18 02:17:21 <zmatt> no I can't tell since I don't know what you mean
Feb 18 02:17:28 <set_> I thought if I got down to the "nitty_gritty," I could learn from the ground up.
Feb 18 02:18:18 <set_> I mean, get this.
Feb 18 02:18:42 <set_> I cannot even install specific libraries on my BBB yet b/c of my lack of knowledge on what goes where and when.
Feb 18 02:18:49 <set_> Does that make any sense?
Feb 18 02:19:33 <set_> Hell. It is not even easy to install them on full-on desktop environments w/ all the CPU power one man can stand.
Feb 18 02:19:41 <zmatt> nope, and it definitely doesn't seem to have anything at all to do with different number bases, nor does it offer any explanation of doing anything with AVR
Feb 18 02:19:51 <set_> Okay. Fine.
Feb 18 02:19:57 <set_> So, why did veremitz say it?
Feb 18 02:20:06 <zmatt> I have no idea, I'd need to know the context
Feb 18 02:20:41 <set_> veremitz: You said and I quote, "You should use a arduino." I think this is what was typed out.
Feb 18 02:20:51 <zmatt> oh, because you literally asked: 01:02 < set_> I need to get some small chips to program.
Feb 18 02:20:51 <set_> I am probably wrong.
Feb 18 02:21:17 <set_> Right. I thought smaller chips had smaller datasheets, TRMs, RMs, and etc...
Feb 18 02:21:18 <zmatt> so he reacted to what you literally asked for... not whether it made sense in context
Feb 18 02:21:26 <set_> Okay. Fine.
Feb 18 02:21:53 <set_> I just had a thought as usual. I got feedback and could not take it. You win.
Feb 18 02:21:56 <zmatt> they usually do, but why exactly do you think you need to read the AM335x TRM? for what specific purpose?
Feb 18 02:22:06 <set_> For programming.
Feb 18 02:22:13 <zmatt> programming what?
Feb 18 02:22:23 <set_> The chip, am335x.
Feb 18 02:22:34 <zmatt> like 99% of the people who program stuff on the beaglebone probably have never ever seen the TRM
Feb 18 02:22:58 <set_> Adafruit_BBIO might not exist in a couple of years and I feel like I am falling behind.
Feb 18 02:23:09 <GenTooMan> actually you need that only if you are touching bare metal.
Feb 18 02:23:17 <zmatt> ideally the only people who'd need to consult them are people who work on the linux kernel
Feb 18 02:23:26 <set_> Oh.
Feb 18 02:24:05 <zmatt> in practice, there can be useful reasons to consult the AM335x TRM as a non-kernel-programmer, but those are limited and rare circumstances, hence I asked for what purpose you needed to consult it
Feb 18 02:24:19 <zmatt> (and even then, you only need very small bits of it generally, not the whole 5000-page thing()
Feb 18 02:24:54 <set_> I thought that was how to make the programs work. Read the TRM, RM, and etc. Then, use common sense, understanding, and logic to reconcile the meaning of what "is" is.
Feb 18 02:25:05 <zmatt> you certainly don't need it for any of the various things I've seen you playing with the past few months
Feb 18 02:25:15 <set_> I know, I know.
Feb 18 02:25:34 <zmatt> I mean, clearly you didn't know, since you just said you thought you did need it
Feb 18 02:25:44 <set_> But. Who knows? One day, I might need it. For instance, I cannot make your script work w/ whatever knowledge I have currently.
Feb 18 02:25:45 <zmatt> although I'm pretty sure I've told oyu this before
Feb 18 02:25:56 <set_> Yes, you have told me before today.
Feb 18 02:26:00 <zmatt> the  TRM contains nothing useful for that
Feb 18 02:26:02 <zmatt> nothing
Feb 18 02:26:22 <zmatt> absolutely nothing in the TRM will help you with getting the servo cape to work
Feb 18 02:26:37 <set_> Okay. Fine. I was reading it the other day and got first hand experience w/ the SPI interface on the chip (am335x).
Feb 18 02:27:15 <set_> This helped me to better understand what it is I need to do w/ SPI and addressing wiring diagrams.
Feb 18 02:27:19 <zmatt> the SPI controller has a working linux driver so you don't need to be concerned with the AM335x-specifics, it uses the standard linux kernel interface, which is why you can use standard python modules for it
Feb 18 02:27:31 <set_> Oh. Okay.
Feb 18 02:27:32 <zmatt> (i.e. smbus2)
Feb 18 02:27:43 <set_> Right, right.
Feb 18 02:27:50 <zmatt> although the main reason you couldn't use my script is because you don't know python
Feb 18 02:27:54 <zmatt> and programming in general
Feb 18 02:27:59 <zmatt> hence, how's that python tutorial coming along?
Feb 18 02:28:13 <set_> Okay. Which Python tutorial? Where is this magic tutorial?
Feb 18 02:28:33 <set_> I read all sorts of tutorials constantly.
Feb 18 02:28:39 <set_> But...
Feb 18 02:28:50 <zmatt> dunno, have you tried one of the top few google results when searching for "python tutorial" ?
Feb 18 02:29:13 <set_> None of them have the smbus2 library in them or other libraries I plan on using at the "moment."
Feb 18 02:29:23 <set_> And no, I have not typed in that exact match of words.
Feb 18 02:29:23 <zmatt> that doesn't matter
Feb 18 02:29:37 <set_> Okay.
Feb 18 02:30:15 <set_> @zmatt: Why does shared-mime-info take so damn long to install?
Feb 18 02:30:56 <zmatt> like, I gave you code that would probably have worked, and avoided the need for you to know anything about the pwm controller, i2c, or python-smbus2 ... but you didn't grasp that, because you didn't understand what you were looking at.  the reason behind that is just general lack of programming knowledge, not knowledge in some specific hardware-related domain
Feb 18 02:31:08 <zmatt> no idea
Feb 18 02:31:44 <set_> Right.
Feb 18 02:31:46 <set_> Okay.
Feb 18 02:31:51 <set_> You said it! But...
Feb 18 02:32:20 <set_> General lack has nothing to do w/ hardware conversioning.
Feb 18 02:33:30 <set_> Literally, I can adapt tons of source in seconds and read algorythm texts to pursue Python, C, C++, or whatever language to issue commands via the console.
Feb 18 02:33:34 <set_> This is not my issue.
Feb 18 02:33:52 <zmatt> lol
Feb 18 02:34:06 <set_> I know you think it is but it is not. I just do not like to program a ton. I think this is why...fine.
Feb 18 02:34:09 <set_> You are right.
Feb 18 02:34:32 <set_> shared-mime-info takes ten years to install!
Feb 18 02:34:50 <zmatt> I've never seen even the slightest evidence that you have any grasp of what python code does
Feb 18 02:35:04 <zmatt> I've never noticed that package taking any significant time to install
Feb 18 02:35:08 <zmatt> why are you installing/updating it?
Feb 18 02:35:09 <set_> If this then that. If not this than that. and etc...
Feb 18 02:35:25 <set_> I am installing python on wsl.
Feb 18 02:35:38 <zmatt> ah
Feb 18 02:35:44 <set_> I want to use it to compile one day.
Feb 18 02:35:52 <set_> High hopes!
Feb 18 02:37:13 <set_> I see people have done it but I have not tried yet.
Feb 18 02:37:23 <zmatt> done what?
Feb 18 02:37:57 <set_> Compiled c/c++ source on it.
Feb 18 02:38:11 <zmatt> on what?  what does that have to do with python?
Feb 18 02:38:15 <set_> Then, cross-compiled to a board maybe. I have not read that much into it.
Feb 18 02:39:04 <set_> Python? Oh! Nothing. It has nothing to do w/ Python. I just wanted to try and install it first to test the capabilities of this wsl2.
Feb 18 02:39:33 <zmatt> I mean, it should basically just be an ubuntu system right?  so pretty much anything should work
Feb 18 02:39:40 <set_> I have debian.
Feb 18 02:39:45 <zmatt> or debian
Feb 18 02:39:45 <set_> Right.
Feb 18 02:39:55 <set_> Well, I am using debian right now.
Feb 18 02:40:30 <set_> I am using debian buster and things are taking "10 years" to install. I am blaming the package shared-mime-info for now.
Feb 18 02:40:42 <zmatt> sounds doubtful
Feb 18 02:40:50 <set_> I am at 50% and it has been at 50% for an hour or more.
Feb 18 02:41:05 <zmatt> sounds like something broke
Feb 18 02:41:11 <set_> Probably.
Feb 18 02:41:32 <set_> I pressed l and it started to work again.
Feb 18 02:41:35 <set_> Odd.
Feb 18 02:43:11 <set_> I was just trying to install git. I forgot to install git w/ gcc and g++.
Feb 18 02:43:12 <set_> Oops.
Feb 18 02:51:52 <set_> @zmatt: Have you ever ssh'ed into the BBB via wsl on Win?
Feb 18 02:52:57 <set_> If not, I am about to try and see if it is possible. Google made a ssh client too. I never one tried their version either.
Feb 18 02:53:07 <zmatt> it works 100% the same as from any other linux system
Feb 18 02:53:09 <zmatt> no difference
Feb 18 02:53:10 <set_> one = once
Feb 18 02:53:16 <set_> Seriously?
Feb 18 02:53:20 <set_> Neat.
Feb 18 02:53:55 <set_> You are right.
Feb 18 02:54:02 <set_> Double neat.
Feb 18 02:55:34 <set_> I have been using PuTTY all these years for a book interpretation.
Feb 18 02:55:49 <set_> It said use PuTTY. Guess what I did?
Feb 18 02:56:01 <zmatt> sure, putty is the classic choice, especially before wsl existed
Feb 18 02:56:19 <set_> Oh. Okay. I must have missed the conversion.
Feb 18 02:57:03 <set_> Do you know how to cross compile to the BBB from wsl?
Feb 18 02:58:20 <zmatt> depends.  if you want to cross-compile code that doesn't really depend on any libraries (other than libc) it's pretty much as easy as native-compiling.  but library-dependencies can become hell
