| 00:02.30 | wpwrak | DocScrutinizer05: do we have a final decision on BMX055 vs. BNO055 yet ? so far, i've seen only "this looks nice" and "there's also this". |
| 00:02.33 | DocScrutinizer05 | ~#neo900 bd is Block Diagram, see http://neo900.org/stuff/block-diagrams/neo900/neo900.html |

| 00:03.12 | Oksana | Ok, so what about BMX055 vs BNO055? |
| 00:03.30 | DocScrutinizer05 | BMX055 is the "stupid" version of BNO055 |
| 00:03.46 | DocScrutinizer05 | BNO has an embedded MC |
| 00:04.02 | DocScrutinizer05 | otherwise all the same sensores |
| 00:04.19 | wpwrak | yes, but do we have a decision yet ? :) |
| 00:04.38 | DocScrutinizer05 | and Nikolaus likes the BNO more, since he already knows that critter. Used in Pyra ;-) |
| 00:04.50 | DocScrutinizer05 | Yes, we have a decission |
| 00:05.07 | DocScrutinizer05 | the winner is: BNO055 |
| 00:05.21 | wpwrak | kewl, thanks ! adding ... |
| 00:05.28 | DocScrutinizer05 | (unless somebody finds some massive flaw in BNO) |
| 00:06.02 | DocScrutinizer05 | until somebody does, I assume the BNO does all the nice stuff BMX does, plus some more |
| 00:06.09 | wpwrak | (and killing that small army of single-function sensors) |
| 00:06.26 | DocScrutinizer05 | yes, which is *great* |
| 00:06.34 | DocScrutinizer05 | and cheaper too |
| 00:06.47 | DocScrutinizer05 | and sensors are even better |
| 00:06.49 | wpwrak | well, one box less. not *that* many, given that BMC180 already was 6-axis |
| 00:07.21 | DocScrutinizer05 | umm, maybe that's correct, yes |
| 00:13.52 | Oksana | Well, I'm just confused that "clever" BNO does not detect free-fall, tab, double-tap (BMX does). That's all. |
| 00:14.02 | Oksana | tap*, not tab |
| 00:17.58 | *** join/#neo900 silviof (~silviof@unaffiliated/silviof) |
| 00:24.12 | wpwrak | hmm, mouser will get the bno055 one week ago. seems that the time travellers have been at it again :) |
| 00:26.29 | Oksana | And since BNO and BMX are too different (size, number of pins), there isn't going to be an option to choose one of the two, right? |
| 00:27.16 | DocScrutinizer05 | Oksana: yes, that's indeed true |
| 00:28.34 | DocScrutinizer05 | but except of (double-)tap and free-fall I found nothing that's missing |
| 00:29.10 | DocScrutinizer05 | and for those 3 we still got LIS302 which can do all 3 |
| 00:29.21 | DocScrutinizer05 | ;-) |
| 00:29.46 | DocScrutinizer05 | when she joins again, somebody please tell her to read chanlog |
| 00:31.13 | svetlana | I did just tell. |
| 00:32.02 | DocScrutinizer05 | :-) |
| 00:32.46 | *** join/#neo900 Oksana (~chatzilla@129.94.239.199) |
| 00:34.16 | DocScrutinizer05 | wonders where from the line "I'm freeeeee, free falling" came in his mind |
| 00:36.47 | DocScrutinizer05 | tap and double-tap are somewhat mutually exclusive ;-) |
| 00:38.51 | DocScrutinizer05 | wonders if we should place BNO055 in lower right corner and LIS302 in upper left. So you could distinguish some acceleration by magnitude from both accels. |
| 00:39.27 | Oksana | Ok, so we replace BMC150+BMG160 with BNO055, LIS302DL stays here (to detect free-fall, tap and double-tap). | somewhat mutually exclusive? Well, you cannot detect them at the same time (and user is not going to tap the phone while it's in free-fall, either), but when two taps are very close to each other, they become double-tap? |
| 00:39.55 | DocScrutinizer05 | yes |
| 00:40.15 | DocScrutinizer05 | all 100% correct |
| 00:41.55 | wpwrak | seems that the interrupt pin of BNO055 is fixed at active-high, push-pull. so it'll need a dedicated input |
| 00:42.06 | wpwrak | (apart from the two new ones for reset and boot mode) |
| 00:43.40 | wpwrak | wonders if ti have the dm3730 also in a 1000+ ball bga :) |
| 00:44.13 | wpwrak | we still want to connect both INTs of the LIS320, right ? |
| 00:46.30 | DocScrutinizer05 | wpwrak: Oh shite! |
| 00:47.05 | DocScrutinizer05 | I guess we might want BMX in the end |
| 00:47.22 | wpwrak | ;-) |
| 00:47.42 | DocScrutinizer05 | toldya embedded MCU might be a PITA |
| 00:48.04 | DocScrutinizer05 | boot???? |
| 00:48.10 | DocScrutinizer05 | daf...q |
| 00:48.43 | DocScrutinizer05 | yes. we would want to keep pur nifty IRQ setup |
| 00:48.48 | DocScrutinizer05 | our* |
| 00:49.20 | DocScrutinizer05 | the purpose of which been to have only two GPIO sacrificed for that |
| 00:50.19 | DocScrutinizer05 | I don't like "windows ACME HID controller" crap |
| 00:50.21 | wpwrak | (boot) it has a nBOOT_LOAD_PIN to tell the boot loader to accept a firmware update. don't ask me why they think they need an extra pin for that ... |
| 00:50.24 | wpwrak | ;-))) |
| 00:50.54 | DocScrutinizer05 | ok, BNO is dead |
| 00:51.31 | Oksana | BMX055, then? |
| 00:51.33 | wpwrak | (when we get an mcu for nfc, and do all those things without extra pin, maybe we should patent it, then license it to bosch for a heap of money ;-)) |
| 00:51.36 | DocScrutinizer05 | I rather thoroughly checked and evaluated BMX, for BNO I was lazy |
| 00:52.16 | DocScrutinizer05 | and I still don't see the need for NFC MCU |
| 00:52.40 | wpwrak | BMX is basically BMC150 + BMG160 in the same package, right ? |
| 00:52.52 | DocScrutinizer05 | NFC has none of the restrictions/requirements that would ask for a dedicated MCU |
| 00:53.00 | DocScrutinizer05 | yep, right |
| 00:53.12 | DocScrutinizer05 | aiui |
| 00:54.24 | DocScrutinizer05 | it's kind of a pity since the accel in BNO has 2 bits higher resolution aiui. But when it needs firmware updates, boot and whatnot, and has a shitty push-pull IRQ, we better forget about it |
| 00:55.22 | DocScrutinizer05 | Nik will frown, but I can't help it |
| 00:56.48 | DocScrutinizer05 | naybe the "higher resolution" is a fake though. Might be 2 LSBs = 0 in 8g mode |
| 00:56.56 | wpwrak | i'll write a mail for the list ... |
| 00:57.00 | DocScrutinizer05 | 1 in 4g mode, 0 in 2g mode |

| 01:03.43 | Oksana | Good night |
| 01:12.50 | DocScrutinizer05 | hugs his Rigol a last time and heads out direction bedroom |
| 01:12.57 | DocScrutinizer05 | ;-D |
| 01:13.58 | wpwrak | ;-)) |
| 01:13.59 | DocScrutinizer05 | OOOOH how discourteous of me. Maybe Rigol also wants to sleep in own bed err bag |
| 01:14.48 | wpwrak | a true gentleneer would let his scope have the bed and sleep on the couch |
| 01:17.23 | DocScrutinizer05 | no couch here and I don't fit into the Rigol softbag |
| 01:18.04 | DocScrutinizer05 | it's a tight but snugly fir for this Rigol |
| 01:18.11 | DocScrutinizer05 | fit* |
| 01:20.42 | Oksana | :-) |
| 01:38.56 | wpwrak | so, no block diagram update for now. i hope we'll have a final verdict on BMX vs. BNO tomorrow. one more thing not to like about the BNO: contains closed firmware. (oh, and the FSF would have a fit, too, i guess ;-) |
| 01:44.47 | DocScrutinizer05 | "FSF would have to fit?" I agree that FSF won't like it, particularly for their RYF "project". But what counts much more: *I* don't like it, particularly since we have not a single benefit from such firmware |
| 01:45.25 | DocScrutinizer05 | I however fail to understand the meaning of "FSF would have to fit" |
| 01:45.47 | DocScrutinizer05 | ooh, mail |
| 01:48.13 | Oksana | would have *a* fit. We are not going to fit entire FSF inside anything, are we? |
| 01:48.34 | Oksana | :-) |
| 01:49.11 | DocScrutinizer05 | I prolly have no idea about the idiom "have a fit" |
| 01:49.32 | DocScrutinizer05 | ooh, but ding has. Yep |
| 01:49.35 | svetlana | "have a fit" http://en.wiktionary.org/wiki/have_a_fit |
| 01:50.02 | DocScrutinizer05 | ~dict have a fit |
| 01:50.06 | Oksana | To experience an epileptic seizure, or to become suddenly enraged. :-) |
| 01:50.13 | svetlana | Yes, exactly. (Etymology is unclear yet though.) |
| 01:50.48 | svetlana | FSF is not known to rage about non-free things; the advocacy doesn't go as far as rage, to my knowledge. :p |
| 01:50.53 | DocScrutinizer05 | "combusted"? that's even more bizarre ;-) |
| 01:51.09 | svetlana | hands a box of matches to DocScrutinizer05 |
| 01:51.14 | DocScrutinizer05 | svetlana: :nod: |
| 01:51.27 | Oksana | Fit: (medicine, dated) A seizure or convulsion. (medicine) A sudden and vigorous appearance of a symptom over a short period of time. A sudden outburst of emotion. A sudden burst (of an activity). Etymology: Unknown, possibly from Old English fitt (âconflictâ). |
| 01:51.50 | svetlana | :o |
| 01:51.55 | DocScrutinizer05 | oooh, yes that fits ;-D |
| 01:52.26 | DocScrutinizer05 | n8 (again) |
| 01:52.36 | Oksana | Good night :-) |
| 01:52.55 | svetlana | nn |

| 01:53.18 | svetlana | (He is sleeping with that box of matches!) |
| 01:53.32 | wpwrak | i'm a bit worried that DocScrutinizer05 may be the one who'll start the zombie apocalypse. already while alive, he goes to sleep a dozen times every day, yet is always awake. |
| 01:53.49 | Oksana | Or does he sleep on it? |
| 01:53.56 | svetlana | ( context: http://en.wikipedia.org/wiki/Polyphasic_sleep ) |
| 01:54.58 | DocScrutinizer05 | a trick of the senses, maybe that's already my AI answering |
| 01:55.22 | Oksana | Neat... |
| 01:56.02 | DocScrutinizer05 | some say I'm only some AI and statements like "I'm going to have a nap" are just to trick you into thinking I'm human |
| 01:56.45 | wpwrak | hah, now it all makes sense ! that's also why you never go to meetings/conferences :) |
| 01:57.50 | Oksana | Nay, not falling for the trick. If there was an AI already advanced enough to do this... It would have been used by military and mining industry first. You are neither. |
| 02:01.44 | DocScrutinizer05 | you're sure? ;-) |
| 02:03.54 | DocScrutinizer05 | Oksana: the mini newsletter is almost perfect |
| 02:04.09 | Oksana | :-) Comments are welcome. |
| 02:05.00 | DocScrutinizer05 | 2 or 3 details need some small adjustment |
| 02:05.49 | DocScrutinizer05 | the scope is not "for testing proto_v2", this sounds like we needed that scope and only that scope and couldn't test proto_v2 without it |
| 02:06.18 | DocScrutinizer05 | it's just another tool in the lab, that augments what and how we can do in R&D |
| 02:08.27 | DocScrutinizer05 | "We do our very best" sounds like we are not sure to succeed. And it lacks a reason why we strive for that. The reason I gave was "reduce number of board spins, by avoiding building a board with bugs we could have avoided if we just had checked more thoroughly beforehand" |
| 02:10.58 | DocScrutinizer05 | the RGB LEDs are a tad on the "too expensive" side before we cpllect funds for sourcing risk parts. We need 8 LEDs per board, x 1000 |
| 02:15.43 | DocScrutinizer05 | (board spins) ... are expensive, and for us take lots of time |
| 03:47.51 | wpwrak | what what what ? 8 of the side-facing RGB LEDs ? we have 6 at the moment, like N900. if you want more, we also need more controllers. |
| 03:48.43 | wpwrak | we also have three top-facing RGB LEDs, one for privacy, two for "aux" |
| 03:52.18 | DocScrutinizer05 | aux are side facing |
| 03:53.59 | wpwrak | oh. so only "privacy" is top-facing ? |
| 04:48.41 | DocScrutinizer05 | yup |

| 15:36.16 | DocScrutinizer05 | which night? |
| 15:36.21 | DocScrutinizer05 | ;-) |
| 15:37.43 | DocScrutinizer05 | nice, you actually met the colors |
| 15:38.03 | DocScrutinizer05 | stay tuned, soon coming |
| 15:38.52 | wpwrak | night = absence of light-carrying particles. since anti-particles can generally be considered largely equivalent to their non-anti counterparts, that would include anti-photons. so when sunlight is visible, it is due to the absence of anti-photons cancelling out the light. ergo this is night. |
| 15:39.31 | wpwrak | (colors) great ! the 4th one is pretty hard to see in rigol's marketing picture :) |
| 15:40.44 | DocScrutinizer05 | it's a tad lighter more ultramarine blue in rigol's display |
| 15:41.24 | DocScrutinizer05 | and the light blue is a tad more turquoise |
| 15:42.15 | DocScrutinizer05 | I already made the poor thing lock up twice ;-P |
| 15:42.41 | DocScrutinizer05 | every key just made a ack click but nothing happened |
| 15:43.28 | DocScrutinizer05 | maybe it didn't like USB and ethernet same time. Or it was the D-Link WLAN stick I plugged to where it expects a flash stick |
| 15:43.35 | DocScrutinizer05 | ;-P |
| 15:45.41 | DocScrutinizer05 | btw re IR: I wonder how they build those 1.4GHz bandwidth IR fiber things |
| 15:45.59 | DocScrutinizer05 | or even higer, 10GHz, 100 1000? |
| 15:48.29 | DocScrutinizer05 | there's a blind spot in my virtual library of reference application notes |
| 15:49.14 | DocScrutinizer05 | well, I guess they use sth like QAM or whatever |
| 15:58.45 | DocScrutinizer05 | sidenote: http://privatepaste.com/7841032023 |
| 15:59.44 | DocScrutinizer05 | idly wonders if USB devices per bus explode at 255 or at 999 |
| 16:00.17 | DocScrutinizer05 | I might manage to reach at least first limit |
| 16:04.01 | wpwrak | should be 127. that's the number of device addresses (this things that get assigned during enumeration) you have. (0 is for the reset state.) |
| 16:06.17 | wpwrak | there must be some sort of routing/filtering at the hub level, though. else, one couldn't enumerate when more than one new device is on the bus |
| 16:18.28 | DocScrutinizer51 | anyway USB would look faintly nice if the protocol in those 3 channels was known |
