**** BEGIN LOGGING AT Wed Jun 26 02:59:57 2019 Jun 26 03:09:01 Maybe another LED or something might help... Jun 26 03:22:00 Well, I made believe the node/bonescript source code could understand one LED as two. I got only so far and now I am receiving this: Jun 26 03:22:21 errro: Unable to write to /sys/class/gpio/gpio1/value. Jun 26 03:22:32 Anyway...the software works but w/ errors during running. Jun 26 03:24:06 https://pastebin.com/GbDRHx8p is the amount of software that keeps telling me I am terrible. Anyway. Yea boy! Jun 26 03:26:23 This is what I think. The node.js people went back in the source of node.js itself to warn people in advance that they were changing things in the future. Beware! Jun 26 04:07:59 set_: it's complaining about the fact that your printStatus function has one parameter instead of two Jun 26 04:08:57 it should be (err,x) instead of (x) Jun 26 04:10:34 btw, did you see my remarks a few days ago? https://pastebin.com/rVDS3pfF Jun 26 12:29:55 ah, someone has found a strategy to have an even lower chance of getting help. instead of asking a vague and overly broad question here, he sent a vague and overly broad question to me in a private message, and then left before I could answer (the answer being to get the fuck out of my PM) Jun 26 12:59:58 m Jun 26 14:42:38 how's x15's routing performance? Jun 26 14:43:21 is an armv8 upgrade anywhere near? Jun 26 14:45:50 I'm not sure but http://www.ti.com/product/AM5728 it's an A15 as well as a dual core 1.6GHz processor can do I guess. It's not designed specifically for routing. Jun 26 14:46:42 hence why I asked whether an armv8 upgrade is near Jun 26 14:47:01 it's damned hard to get arm boards with dual ethernet ports Jun 26 14:48:21 true, they would have to use the keystone line which gives I believe 2 10G and from 0 to 8 1G ports. Jun 26 14:48:44 you mean TI? Jun 26 14:49:00 or beagle Jun 26 14:49:04 Well beagle boards tend to use TI SoC Jun 26 14:49:41 fine. I"m gonna google for ti keystone Jun 26 14:52:44 but is x15 enough for a residential gateway? Jun 26 14:55:30 It appears to be primarily for industrial or entertainment based on the feature set. The IC has 2 1Gig ethernet ports but only 1 is brought out on the X15 you might be able to bring out the second one if you can connect a PHY via IO expansion might be tough because the PHY requires strict control of the signal lines. Jun 26 14:57:07 so I have to write driver to process ethernet frames on the second one? Jun 26 14:57:55 that would be cute, since my telecom router talks in pppoe Jun 26 15:12:53 Well my thinking is it should just work, no driver needed. Because the drivers are already written it should recognize the new available ethernet port. If not likely some tweaks in configuration would do it Jun 26 15:14:07 that's what the i2c EEPROM device IO port configuration is for anyhow. Jun 26 17:37:20 GenTooMan: uhh no the X15 has two gigabit ethernetports Jun 26 17:38:54 thanks zmatt, always good to be sure things are correct Jun 26 17:39:32 emfipp_: "routing performance" sounds much too vague to give a clear answer, performance will no doubt depend heavily on exact workload, kernel, and configuration Jun 26 17:40:40 also why do you think ARMv8 matters? TI does have a new SoC with ARMv8 cores, but I'm pretty sure they are slower than the ARMv7 cores on the AM572x Jun 26 17:46:31 some keystone SoCs have cool stuff like hardware acceleration for some networking/routing tasks, but those processors are pretty special-purpose and I doubt there are (relatively) low-cost boards based on them Jun 26 17:47:28 just buying a decent router would be cheaper and simpler Jun 26 17:48:40 maintenance for 32-bit arm in upstream projects seems to be on the decline... Jun 26 17:51:17 ? Jun 26 17:55:22 zmatt: i don't think ARM has anyone working on 32-bit in the kernel anymore, for example Jun 26 17:55:29 at least, not officially Jun 26 17:57:58 there are so many millions of 32-bit arm linux devices still in active use, I'm not particularly worried Jun 26 17:58:35 true enough Jun 26 18:00:51 given TI's current focus markets, it makes perfect sense they're not in a huge hurry to use the latest and greatest cores Jun 26 18:07:10 They are focused on industrial which does not used the latest and greatest and have a VERY long service life. Industrial is typically 40 years. The only thing that's been driving new cores is cell phones and IoT type devices. Those are concerned about power more than performance. So it makes sense. Jun 26 18:09:43 "IoT type devices" seems doubtful, although it's vague to the point of meaninglessness anyway :P but yeah, TI was chasing new cores when they were still making OMAPs, and they've been riding those out for a while now, with the AM57xx being strongly derived from OMAP5 Jun 26 18:11:23 looks like they're now trying to switch to using a Keystone-based architecture for their SoCs, with the introduction of the remarkably "normal" (in terms of peripherals, interfaces, and pricing) K2G devices and more recently the clearly Keystone-derived AM65xx Jun 26 18:30:34 oof, looks like am65xx SR1.0 has some "fun" errata Jun 26 18:31:05 power connections may not be connected to external balls? ;) Jun 26 18:31:16 zmatt Errata 0: nothing works give up hope ye who press enter here? Jun 26 18:33:20 usb3 is entirely broken for one Jun 26 18:33:45 that is bad. Well it is in engineering samples. Jun 26 18:34:36 all yuv pixel formats are broken in dss somehow, which is probably a bit inconvenient when doing anything with video Jun 26 18:35:46 ecc scrubbing needs to be disabled since it may cause memory corruption Jun 26 18:36:12 some headaches with power supplies Jun 26 18:36:18 you know... fun stuff :) Jun 26 18:36:51 I wonder which revision of cortex-a53 they use, since that thing also has some awkward errata Jun 26 18:49:09 as I said good thing it's still in engineering samples, although if they have errata it means they already made the masks. Fixing those will not be cheap. **** BEGIN LOGGING AT Wed Jun 26 20:03:59 2019 Jun 26 20:29:07 re Jun 26 21:41:35 zmatt: Yes. I found the info. about the (err, x) in the function parameters instead of just one parameter. I also reviewed that info. about the PRU on the BBBlue. I understand what you are saying. I guess my question should have been related to how is input related. Jun 26 21:41:36 ... Jun 26 21:41:52 So... Jun 26 21:42:14 How is input via PRU related to making the BBBlue understand ArduCopter source? Jun 26 21:42:25 This is something I just do not get for now. Jun 26 21:43:11 I mean. I can go in to the PRU source on ArduCopter for viewing their ideas of making it work. Jun 26 21:43:43 But...I think w/ the lack of experience on my end w/ PRU, input via PRU is way past my scale for now. Jun 26 21:43:51 Aw! Jun 26 21:49:42 https://github.com/ArduPilot/ardupilot/tree/cd5c59773bb5d4d4cdd4ba77437b3ede40ff8662/Tools/Linux_HAL_Essentials/pru/aiopru is what I found so far. Jun 26 21:49:43 ... Jun 26 21:50:01 I will try some more things before falling into oblivion. Jun 26 22:10:27 anyway...bbl to finish up on this PRU instance and input some ideas into the BBBlue for flight"ness". Jun 26 22:16:16 set_: I don't understand your question Jun 26 22:19:43 that link suggests arducopter supports the bbblue Jun 26 22:19:47 so what's your question? Jun 26 22:21:41 note that it appears to use uio-pruss to load firmware, so make sure your /boot/uEnv.txt enables the AM335X-PRU-UIO overlay rather than one of the AM335X-PRU-RPROC overlays (via the uboot_overlay_pru variable) Jun 26 22:52:06 Okay. Jun 26 22:53:05 So, does the BBBlue work as is w/out a bunch of self-written source b/c of the ardupilot software? Jun 26 22:53:06 Or... Jun 26 22:53:19 Would I need to supply my own source based on their software? Jun 26 22:53:51 I don't know anything about what ardupilot does or doesn't do or how it is used Jun 26 22:53:59 Okay. Jun 26 22:54:49 No issue. Jun 26 22:54:56 Neither do I. Jun 26 22:55:32 I guess it is a well maintainted bunch of source that can work w/ the BBBlue or other am335x boards from BeagleBoard.org. Jun 26 22:56:09 I think that I need to get some more ideas circulating from their repo on github.com... Jun 26 22:56:29 I typed that b/c nothing has worked so far. Not even followin' the directions to the tee. Jun 26 22:57:07 @zmatt: No issue, though. It is not your issue. I get this idea. Jun 26 22:57:36 I have a schematic made up from mawk and I will try that idea out. Jun 26 22:57:42 ... Jun 26 22:59:32 https://imgur.com/EG7mOLO is the photo of the level shifter. It has a dated but useful set of instructions from TI.com. Jun 26 22:59:33 ... Jun 26 23:00:58 I guess this is my last chance on things. Anyway...do you think that the 1.1v on the PRU would be an issue for changing logic to 5v from 3.3v on the am335x on the BBBlue? Jun 26 23:01:32 hi set_ Jun 26 23:01:38 mawk! Jun 26 23:01:39 Hello. Jun 26 23:01:57 I keep looking at things incorrectly. Jun 26 23:02:18 The path is not from pru to 5v logic (receiver). Jun 26 23:02:30 set_: it was a remark in parenthesis where I literally said "but that's Jun 26 23:02:36 irrelevant since it's completely internal to the AM335x" Jun 26 23:02:39 I know. Jun 26 23:02:46 so why then do you ask about it? Jun 26 23:03:11 also you don't want to convert from 3.3v to 5v but the other way around Jun 26 23:03:22 B/c...I am trying to understand the connections which must be beyond my understanding. Jun 26 23:03:25 Aw! Jun 26 23:03:31 See. That is just what i figured out. Jun 26 23:03:35 (from sbus output to pru input) Jun 26 23:03:39 Right! Jun 26 23:03:47 input = pru! Jun 26 23:03:59 I keep getting that incorrect w/ the set up of the hardware. Jun 26 23:04:02 you said it was a rx pin from your device Jun 26 23:04:05 last time Jun 26 23:04:08 <--- foolish at times Jun 26 23:04:09 so now it's tx ? Jun 26 23:04:15 I think so. Jun 26 23:04:18 I was incorrect. Jun 26 23:04:28 the level shifter you showed can still be used Jun 26 23:04:28 yeah it's the output of a wireless receiver module of sorts Jun 26 23:04:40 ah, I see Jun 26 23:04:44 mawk: I remember you saying something about that last time. Jun 26 23:05:03 I have to interpret things backwards right? Jun 26 23:05:03 yes it converts Vcc to Vdd and Vcc can be > Vdd or < Vdd, doesn't matter Jun 26 23:05:06 so you can use it both ways Jun 26 23:05:11 Okay. Jun 26 23:05:12 no, it goes from input A to output E, always Jun 26 23:05:17 Oh. Jun 26 23:05:20 if you need to convert both ways you need two shifters Jun 26 23:05:27 I just change out the Vcc and Vdd, right? Jun 26 23:05:32 it just has 4 channels, hence inputs A B C D to outputs E F G H Jun 26 23:05:32 Oh. Jun 26 23:05:38 Got it. Jun 26 23:05:55 Oh. So, A to E and etc... Jun 26 23:05:58 yes Jun 26 23:06:23 but that's just one level shifter among many, use the cheapest/best available one that suits your specs Jun 26 23:07:09 Okay. I was thinking differently. So, instead of using the Vcc to power the module, I use Vdd? Jun 26 23:07:25 module = level shifter Jun 26 23:07:53 it takes care of the details for you Jun 26 23:08:00 Vcc is your input voltage, Vdd is your output voltage Jun 26 23:08:03 I think, check schematic Jun 26 23:08:09 I am slow on using this devices still to this day. It is like the info. will not stick to me. Jun 26 23:08:10 Okay. Jun 26 23:08:19 Checking info. Jun 26 23:08:20 normally Vcc means input voltage for bipolar transistor based circuits, and Vdd for FET based circuits Jun 26 23:08:30 here it's a bit meaningless they use it both for just "power input" Jun 26 23:08:54 c is collector, d is drain Jun 26 23:09:22 Vcc is the low voltage supply. Jun 26 23:09:32 it's interchangeable Jun 26 23:09:35 Oh. Jun 26 23:09:38 Vcc can be higher than Vdd Jun 26 23:09:55 Vcc is voltage for inputs A B C D and Vdd is voltage for outputs E F G H Jun 26 23:10:01 (or other way around, check) Jun 26 23:10:01 Oh. Jun 26 23:10:05 Okay. Jun 26 23:10:07 Checking. Jun 26 23:10:21 and it wants CMOS type logic levels, eg a logic high is > 0.7 Vcc Jun 26 23:10:23 usual stuff Jun 26 23:10:28 set_: btw, what makes you think that the sbus signal from your X8R (that was the one you use right?) is 5V ? Jun 26 23:10:53 Right. Jun 26 23:11:01 I willl look again. Jun 26 23:11:34 I thought since it was powered via 5v (4v to 10v), I could use this 5v circuitry to make it work. Jun 26 23:11:49 mawk: I saw the truth table. Jun 26 23:12:10 yes Jun 26 23:12:16 as usual with all this RC stuff there seems to be a serious lack of clear documentation, but I'm cautiously getting the impression that the sbus signal is 3.3V Jun 26 23:12:34 Okay. Jun 26 23:12:35 ignore the complicated Enable A/B/C/D pin set_ , truth table will just make a logical 1 at E if you have a logical 1 at A Jun 26 23:12:41 and same with logical 0 Jun 26 23:12:44 although it would be very wise to confirm this before connecting it directly to a beaglebone blue Jun 26 23:14:16 hmm, now I'm getting less sure Jun 26 23:14:21 The truth table says what you stated. Vcc is input while Vdd is output. Jun 26 23:14:51 why the fuck is this sort of basic stuff so hard to find for these devices. is it really so hard to put stuff like this in the datasheet? @!#! Jun 26 23:16:23 So, I can basically input one pin "A", PRU 15 via UIOPRU, like w/ what ardupilot wants, and then output the same pin w/ pin "E." Jun 26 23:17:04 Then, I can supply the voltage and use those two i/o pins as a bridge. Jun 26 23:17:23 That is this cmos shifter. Jun 26 23:17:36 ... Jun 26 23:18:13 x8r sbus output -> pin A of level shifter, pin E of level shifter -> E4.4 of bbblue Jun 26 23:18:19 zmatt good data sheets are getting rarer. For example many don't bother to book mark there data sheets anymore. It makes it hell when you have a 79 page data sheet with 19 sections and numerous subsections. Jun 26 23:18:33 Speaking of voltage dividers/shifters, I just got a 3.3v (in the mail) LCD screen to use. That last one from the directions was bogus. Jun 26 23:18:33 ... Jun 26 23:18:53 GenTooMan: lol I wish it were 79 sheets, it's 2 Jun 26 23:20:00 @zmatt: That is what I was thinking. I am hesitant. Since this is input, I would hate to bulge some input of a heavy circuit into my BBBlue. Should I use any other things, i.e. resistors or etc? Jun 26 23:20:23 set_: ? Jun 26 23:20:32 I am serious. What if? Jun 26 23:20:52 That voltage divider/shifter is all that needs to happen? Jun 26 23:20:57 set_: as long as you power the output-side of the level shifter using the 3.3v from the beaglebone, nothing can break Jun 26 23:20:58 as a bridge? Jun 26 23:21:17 Okay. That makes sense. Jun 26 23:21:26 you can use a series resistor if you want for peace of mind, it shouldn't be needed but it doesn't hurt either Jun 26 23:21:34 I think I was interpreting what you typed incorrectly again. Aw. Jun 26 23:22:04 I need to listen to jkridner, i.e. use a oscilloscope to see the evidence. Jun 26 23:22:06 if you screw up and manage to put 5v or something on the beaglebone pin, a series resistor probably isn't going to protect it really anyway Jun 26 23:22:09 yep Jun 26 23:22:16 Right. Jun 26 23:22:32 I wonder what would happen in that case zmatt Jun 26 23:22:42 it would go through a protection diode no ? if there's a resistor not much harm done Jun 26 23:22:45 I wouldn't want to try tho Jun 26 23:22:45 I think I can (Thomas Train 1985). Jun 26 23:23:18 It is time to test. Jun 26 23:23:21 bbl Jun 26 23:23:30 set_ tell us about the smoke? Jun 26 23:23:33 current would be forcefully injected into the 3.3V rail Jun 26 23:23:36 mawk: the protection diode is for diverting esd, it doesn't protect against continuous overvoltage. the pin could still go a diode-drop above 3.3v, which is absolutely too much Jun 26 23:24:02 GenTooMan: YOu got it, chum! Jun 26 23:24:05 ah, I see Jun 26 23:24:53 I guess the series resistor would still help, it'll make the destruction less instant Jun 26 23:26:21 Just to make sure, as I type this up, 3.3v to Vss? Jun 26 23:26:27 what ? Jun 26 23:26:29 Vss means ground Jun 26 23:26:33 Oh. Jun 26 23:26:34 Dang. Jun 26 23:26:35 like Vee Jun 26 23:26:41 Vss is ground for FET based circuits Jun 26 23:26:41 I am glad I did not test it yet. Jun 26 23:26:42 s for source Jun 26 23:26:46 Aw. Jun 26 23:26:57 and Vee for bipolar transistor based circuits Jun 26 23:27:05 e for emitter Jun 26 23:27:06 Got it. Jun 26 23:27:11 now you know all the names about transistors ! Jun 26 23:27:11 e is for emitter. Jun 26 23:27:20 Vdd = dwain .. or drain :D Jun 26 23:27:46 I have read about some complicated transistors. BJT and etc. Jun 26 23:28:03 All of them w/ their own particular set up and tear down. Jun 26 23:29:09 So, basically it is one wire to the shifter and one away from the shifter to the BBBlue? Jun 26 23:29:15 Nice. Jun 26 23:29:15 yes Jun 26 23:29:20 it's in series in your data line Jun 26 23:29:25 Okay. Right. Jun 26 23:29:34 set_: ;-) Jun 26 23:29:59 so if you have a 5V output you set Vcc = 5V, A = SBUS output, Vdd = 3.3V, E = bbb input Jun 26 23:30:07 check before the meanings of Vcc and Vdd I'm not extra sure Jun 26 23:30:14 Okay. Jun 26 23:30:21 but I guess that's it, I remember a fet circuit after the shifter Jun 26 23:30:25 push pull Jun 26 23:31:02 http://www.ti.com/lit/ds/symlink/cd40109b.pdf is the schematic and diagram. Jun 26 23:31:27 I thought this was a unidirectional shifter. Jun 26 23:31:48 bidirectional, I guess. Jun 26 23:33:08 uhh no? Jun 26 23:33:33 uni or bi! Jun 26 23:33:40 it's unidirectional Jun 26 23:33:54 I just read the info. It can be either. Jun 26 23:34:02 then you misread it Jun 26 23:34:18 I already told you the last time and this time set_ Jun 26 23:34:23 it's not bidirectionnal Jun 26 23:34:36 [01:05:12] .:mawk:. no, it goes from input A to output E, always Jun 26 23:34:36 [01:05:20] .:mawk:. if you need to convert both ways you need two shifters Jun 26 23:34:47 bidirectional bussing means what? Jun 26 23:35:27 than you can't down level and up level at the same time, in this context Jun 26 23:35:34 you need two chips if you want both directions Jun 26 23:35:50 (you don't need both directions) Jun 26 23:35:57 Right. Jun 26 23:36:03 I understand. Not right now. Jun 26 23:36:13 I might need tri! Jun 26 23:36:34 Just playin'. Jun 26 23:36:48 * zmatt checks out and goes to do other stuff Jun 26 23:37:15 Later @zmatt. Jun 26 23:37:24 As usual, it has been fun. Jun 26 23:37:34 "OFF TO TEST, BOY!" Jun 26 23:38:13 bbl...testing will ensue. Jun 26 23:50:13 I'll wait for the quiet boom Jun 26 23:51:38 BOOM Jun 27 00:59:55 Well...fellows. Jun 27 01:00:02 I tried. That is all I can do. Jun 27 01:00:28 No motor interaction w/ the ESCs and the arducopter software is on the BBBlue. Jun 27 01:00:46 I got the damn thing to work w/ an Arduino but that does not count. Jun 27 01:01:08 ... Jun 27 01:01:15 I tried these combos: Jun 27 01:01:31 All pins from the sBus: GND, Signal, and Power. Jun 27 01:02:40 I attached each to the breadboard along w/ the pinmux for the TI CD40109B. Jun 27 01:03:32 So, sBus power to Vdd on the switch. And, GND to gnd. Jun 27 01:03:42 GND = Vss. Jun 27 01:05:13 I tried. The 3.3v/Encoder 4 to the Vcc/switch. Jun 27 01:05:24 and Blah! Jun 27 01:05:50 No smoke, no foul, no one hurt. Yea! No working order, no flying, and no output. Boo! Jun 27 01:07:10 There must be some software I am missing. Oh well. Onto not caring again. Jun 27 01:20:20 https://pastebin.com/SmqYJkPs was the set up for me before trying other things. Jun 27 01:20:23 set_ how about if you get a logic probe and check the output signals first? Jun 27 01:20:24 brb Jun 27 01:20:32 Good idea. Jun 27 01:20:44 Logic probe. Jun 27 01:20:52 What is that? Oscilloscope? Jun 27 01:21:35 I can do it. Do I need to get a multimeter or oscilloscope? Jun 27 01:21:43 set_ sometimes I have ideas or they have me, Technically it could be a comparator driving an LED (going on and off) it just senses the state of an output or input. Jun 27 01:21:56 Okay. Jun 27 01:21:57 Got it. Jun 27 01:22:03 I will test more and test more. Jun 27 01:22:27 set_ just don't blow your mind it's a terrible thing Jun 27 01:22:45 GenTooMan: Okay, Okay. Man or yea boy! Jun 27 01:23:07 I keep trying over here. Years in the making. Jun 27 01:23:14 Flying a BBBlue over CinCin. Jun 27 01:23:30 Vroom. What a nightmare! Jun 27 01:23:49 set_ you can look up or buy a logic probe. But in the mean time you can use an Oscope to observe a signal as well. Jun 27 01:25:05 Okay. I need to take a break. brb. I will look up logic probe later. Jun 27 01:25:16 GenTooMan:! Jun 27 01:31:46 Logic Tester...0 or 1 or switching! Jun 27 01:31:55 Got it. I will have to one day. Jun 27 01:37:10 set_ not just a good idea a great idea in that case. A common embedded software debug tool is actually an oscope you need one really. Jun 27 01:39:30 I have a bottom line one. Jun 27 01:40:04 I rarely use it. Not only did I invest in cheap instrumentation, I am cheap enought to preserve it by not using it. Jun 27 01:40:49 Usually, I just check for volts coming out of the pinage. Jun 27 01:40:50 set_ sigh... the oscope can tell you considerable number of things. IE switching not switching voltage frequency etc. Jun 27 01:41:05 Oh. Jun 27 01:41:06 Okay. Jun 27 01:43:08 set_ use the trigger to see if the signal is changing (at all) if not that means nothing is actually happening. Not saying doing so is easy but it is doable. Jun 27 01:49:10 trigger? Jun 27 01:49:19 You mean on the BBBlue? Jun 27 01:49:38 or the Oscope? Jun 27 01:50:18 oscilloscope I hope you have used one at least :D Jun 27 01:50:51 I think the only issue I would come across is the PRU pin, the 3.3v pin, and the GND pin on the Encoder 4 pinage. Too tiny. Jun 27 01:51:04 Oscope trigger. I should learn how to use that tech. more. Jun 27 01:52:14 set_ yeah... that would make your testing a whole lot easier. As for small pins they probably don't have test pads. If there are vias connectted to them I often use 30AWG wire and connect the wire to the via. Jun 27 01:55:05 It takes some careful work and eye strain but doable Jun 27 01:56:40 I have some premade terminal pins for the BBBlue. This can be useful on this situation. Jun 27 01:57:16 I am learning right now on the Tektronics for triggering (rising and falling edges). Jun 27 01:58:34 I would start with the test stuff on the scope for doing that. Their should be some signal on the scope face for that, usually it's a weird looking chunk of metal that looks like a loop for you to clip the probe on. Jun 27 02:02:20 I am learning about the runt triggering right now. Nice! Jun 27 02:02:35 Digital anomolies! Jun 27 02:03:35 Should I go and plug this sucker in or what? Jun 27 02:03:45 bzzt, bzzt? Jun 27 02:04:18 and what is the first test I need to make? Do I need to make a test on the CD40109B or on the BBBlue or the Receiver? Jun 27 02:06:14 I would start at the CD40109B output then check the input (that should check the BBBlue output also) Jun 27 02:07:14 the input levels should be logically the same as the output levels at the very least (not by voltage but logic level wise). Jun 27 02:07:56 Okay. Jun 27 02:08:29 So, use power outside of the scope or just the scope? Jun 27 02:08:36 I am real new w/ the scope business. Jun 27 02:09:37 So like this: Vss from the CD40109B to the GND on the Scope. Jun 27 02:09:38 ? Jun 27 02:09:41 And then... Jun 27 02:10:21 Power from the Scope (Positive) to what inputs or what outputs? Like I say, I am new. Jun 27 02:11:24 e.g. maybe on "A" or Enable "A"? Jun 27 02:11:42 just to make sure the switch is in working order? Jun 27 02:12:01 I guess I got it now. Jun 27 02:12:22 you should need power just ground, you are testing a signal not if you can measure the power :d Jun 27 02:12:34 I can use Vss for GND. Then, I will test all avenues/pins on the CD40109B. Jun 27 02:12:35 Right. Jun 27 02:12:48 I just thought this may be more tricky than easy. Jun 27 02:13:10 shouldn't need LOL geesh I am gettng oldish. Well anyhow checking the enable pin might be good see if it toggles when you think it should. Jun 27 02:13:24 GenTooMan: I think you just talked me into testing. Jun 27 02:13:26 I understood. Jun 27 02:14:04 Off to test! Jun 27 02:14:14 brb w/ findings. Jun 27 02:27:58 the enable pin should be tied high in his case Jun 27 02:36:25 Okay. Jun 27 02:36:32 The Oscope states things. Jun 27 02:36:38 Like... Jun 27 02:36:47 Overcompensated. I did not fix this yet. Jun 27 02:37:18 I have to fix this overcompensation before using it. It is too late to goof around and goof up my machine. Jun 27 02:38:04 And they ripped me off. They did not provide the logic analyzer like stated they would in the materials. Jun 27 02:42:49 set_ or it's actually just an LED :D anyhow just be patient and do things methodically. Think before you act. Incidents are planned etc. Jun 27 02:43:03 Right-o. Jun 27 02:44:05 Hey GenTooMan: The machine did come w/ a plastic device, sort of like a driver, where I can use it to adjust the probe. Jun 27 02:44:25 The "instructions" stated try not to use something metal. Jun 27 02:44:32 Ha. Jun 27 02:45:04 Plastic drivers are not abundant. Jun 27 02:46:44 I guess some sandpaper and some normal plastics would do just fine if I lose this plastic driver piece. Jun 27 02:47:16 Anyway...I will test soon. I found out how to use it online. The materials fell short of entertaining. Jun 27 02:52:08 set_: https://photos.app.goo.gl/Q264RTqUWPeseNsn7 Jun 27 02:53:38 I saw it. Jun 27 02:53:55 I will test that soon. **** ENDING LOGGING AT Thu Jun 27 02:59:57 2019
