**** BEGIN LOGGING AT Wed Aug 03 02:59:57 2022 Aug 03 03:01:31 Has anyone embedded the BeagleBone into a rugged enclosure with ports for power, GPIO etc. aka like a mini computer like  NUC or other mini PC? I am really interested in starting a business to do that if there is any sort of market for that. Most of the times I am struggling getting I/O pins especially glued on the P9/P8 connectors and getting Aug 03 03:01:32 regulated power from different sources. Aug 03 03:03:04 I want to do a full PCB layout with the BeagleBone installed on it and have a buck-boost converter to regulate power and trace out the I/O pins, Serial, USB, put in a CMOS battery circuit to keep clock Aug 03 03:04:26 Guest3742: I saw someone inc. the BBG to a CNC machine once or twice. Aug 03 03:05:25 There is the older version RepliCape too. It handles CNC and 3D Printing. There used to be a group or a person that handled the PocketNC too. Aug 03 03:05:40 That thing was nice. Aug 03 03:06:29 I have had some vendors of mine incorporate the board into their devices, especially RFID readers and they are super reliable. I have some of these that have worked for years without a glitch. Aug 03 03:07:18 Yeppers! I noticed that too. Did you ever want to build around the am335x, i.e. outside of a BBB or other related board? Aug 03 03:08:48 I got a chip a while back. OSDxxxxx from https://octavosystems.com/category/beaglebone-black/ . Aug 03 03:09:13 I wanted to do something w/ it but failed. I could not do it as easy as mentioned from the .org. Aug 03 03:09:28 Yeah I would love to do something like that. but I have worked full time for 17+ years, which means that I am more on the management side and it's impossible for me to get down to building stuff unfortunately Aug 03 03:09:51 Me too! Well, I am no manager. I mow. Aug 03 03:10:15 But...I am an avid learner when it comes to picked and placed needs/wants. Aug 03 03:10:36 But there is scant knowledge in our group on Linux as the whole focus is on Windows development. But with the advent of IoT, it's been a godsend as a hardware engineer to actually be able to work on device level stuff and not just as a hobby but get paid for it! Aug 03 03:11:14 Ya, ya. Funding. I know...it makes the world go around. Aug 03 03:11:20 Cash is king. Aug 03 03:11:20 I am working on feeding RFID, BLE tags, LoRaWAN tag data into other systems Aug 03 03:11:26 Nice. Aug 03 03:12:18 When 5G really hits and starts enabling massive machine to machine communications, there is going to be a tremendous amount of growth in embedded systems Aug 03 03:12:20 I have a click board for RFID. Aug 03 03:13:17 I never once did anything w/ it. I have owned this click for years, i.e. seven yrs. Aug 03 03:14:16 I read a headline, do not laugh, 7G. I wonder if I can find it. Aug 03 03:14:25 I usually get serial data from RFID readers and push them into other systems, the BeagleBoard is the perfect footprint for that. Raspberry Pi was also considered though I don't know why it did not happen Aug 03 03:15:42 Yeppers. I think so too. There are some nifty things about Open Source hardware/software. Aug 03 03:15:48 Yeah 7G is vaporware for now, it will take some years for 5G to actually fully get implemented and for us to feel the benefits too Aug 03 03:16:02 Oh. Aug 03 03:16:16 I read a bit into it. Something about lower latency will be gained. Aug 03 03:16:33 But, you are right. Aug 03 03:16:37 I was in DC the other day and at one location I got 1.1 Gbps on 5G, it was just incredible to even fathom. I took a screenshot and sent it to every nerd I know. Aug 03 03:16:37 Down the road. Aug 03 03:16:55 Fast...vroom. Aug 03 03:17:48 Guest3742: I always wanted to use that RFID click w/ a lock. I see people use them w/ BBBs from the past. Aug 03 03:18:31 I have fiber at home and max I will get is usually around 800, once they become pervasive, it will be just incredible. I can't reveal who I work for but there are division which work on vehicle to vehicle communication technologies, you will not need a waze app eventually, the cars will talk to each other when congestion starts and provide Aug 03 03:18:31 alternate routing to help everyone Aug 03 03:18:58 Now, the BBB by itself is bulky for end use in locks but for testing the am335x, it is perfect. Aug 03 03:19:00 Oh. Nice. Aug 03 03:19:16 That is a bit scary to me. Aug 03 03:19:23 Yep definitely scary Aug 03 03:19:35 Less control and more trust. Aug 03 03:20:25 Oh...you mean. Like, lane three in two seconds will take you to Park Ave. to get you to the coral sightings? Aug 03 03:20:26 ha. Aug 03 03:20:28 Everything comes at a price. You can imagine situations like an emergency hurricane or wildfire evacuation where you can route everybody quickly and safely so there are going to be some benefits. Aug 03 03:21:11 Right. You are right. Emergencies where things and people need to be evacuated are serious. Aug 03 03:21:29 Then, there are people that sit in their backyard during the Cat 4 storms. Aug 03 03:21:37 Odd w/ little trust. Aug 03 03:22:12 Weather is another nifty tool for communication. Aug 03 03:22:35 I saw a weather station based around the BBG already. Aug 03 03:23:02 Yeah I am going to help my daughter do something similar to that for a school project Aug 03 03:23:18 It was cool and hot, both actually, and I almost got it to work. Aug 03 03:23:50 https://beagleboard.org/p/lloydcbailey/gprs-weather-station-ea5d35 Aug 03 03:23:56 Nice...weather is awesome when you live in it. Runnin' from it creates panic. Aug 03 03:23:57 Nice. Aug 03 03:24:03 I will check that out now! Aug 03 03:25:08 I missed that one. Aug 03 03:25:25 Neat. Aug 03 03:25:32 Nice chat! Got to run, will try to be back here when time permits! Aug 03 03:25:40 Godspeed! Aug 03 20:07:00 hi, question about DS18B20 temp sensor. In arduino and esphome I use address as 0x6e0300a279d76428, I'd like to use same scheme in my software, 28 in the end is pretty simple as I can read it from directory name 28-0300a279d764, but from where can I get 6e crc? Aug 03 20:07:01 I can find it only in dmesg during boot. `w1_master_driver w1_bus_master1: Attaching one wire slave 28.0300a279d764 crc 6e` Aug 03 20:09:23 pszafer: uhh, the crc is not an actual part of the address, it's just a crc (a checksum used to protect against data corruption) Aug 03 20:11:02 so you could compute it from the rest of the address but I don't really understand why you would care, since the kernel handles the protocol layer Aug 03 20:12:11 zmatt do you what's the method to compute CRC from this? `0300a279d764` Aug 03 20:12:57 zmatt do you know what's the method to compute CRC from this? `0300a279d764` Aug 03 20:14:49 the 28 is part of the address... you can find the crc computation details in the DS18B20 datasheet or any other 1-wire protocol documentation Aug 03 20:15:23 though I still don't understand why you care, as long as you're using the kernel driver there should never be any need to concern yourself with crc computation Aug 03 20:18:06 beware btw that implementing 1-wire using a gpio on linux (i.e. using the w1-gpio kernel driver) is inherently inefficient and unreliable, compared to e.g. i2c Aug 03 20:19:15 zmatt thanks, I'm looking for that. In my software people will use interchangeably ds2482 i2c bus for ds18b20 and w1-gpio. DS2482 library I use has address similar to esphome. So I wanted to provide posibility to move temp sensor betwenn buses Aug 03 20:19:22 good to know! Aug 03 20:19:24 thanks! Aug 03 20:21:02 using an i2c-to-1wire bridge like that should avoid the issues of the w1-gpio driver yeah Aug 03 20:21:20 is there no kernel driver for this bridge? Aug 03 20:21:48 there is Aug 03 20:22:14 so if you use the kernel driver for the ds2482, the kernel should hide the differences between using it versus using w1-gpio Aug 03 20:29:40 you're right, never thought of it :) Aug 03 20:30:02 e.g. using a dt overlay: https://pastebin.com/raw/2erALYwa Aug 03 20:30:32 or you can create an instance at runtime via sysfs as shown here: https://docs.kernel.org/w1/masters/ds2482.html Aug 03 20:30:59 in either case, use the correct i2c bus and the appropriate i2c address (in range 0x18 .. 0x1b depending on the AD0/1 pins) Aug 03 20:32:42 (y) Aug 03 21:02:52 Hello,  I need to get into contact with Jason Krinder regarding a pending donation to the charity. Does someone have a phone number I can have to reach out to him? Aug 03 21:04:40 I tried the number on the website but it isn't connecting. My email is warmon@nptrust.org. Aug 03 21:04:52 jkridner: ping Aug 03 21:05:28 Guest27: have you emailed him? **** ENDING LOGGING AT Thu Aug 04 02:59:57 2022
