houkime | S901: 1v8 decoupling is missing. Also looks like inappropriate number of decouplers for so many spacially separated pins | 00:02 |
---|---|---|
houkime | *spatially | 00:03 |
houkime | inappropriate decoupling is a problem throughout several sensors on neo900 it looks like | 00:04 |
Joerg-Neo900 | add decoupling as you see fit | 00:04 |
houkime | filled a bit my new issue tracking page. https://notabug.org/Houkime/Neo900-Issues/issues | 00:21 |
houkime | it was just some blocks on UPPER using GND (from LOWER) for some reason instead of default GND3. | 06:28 |
houkime | fixed that | 06:28 |
houkime | https://notabug.org/Houkime/Neo900-Issues/issues/1 | 06:29 |
houkime | However there is a thing with microphones using GND3 on LOWER for some reason. | 06:29 |
houkime | they are digital mics, so no real reson for them to have a separate ground i guess? | 06:30 |
houkime | also, I doubt thhey can work on S2. | 06:31 |
houkime | in simsw.pdf there is a picture of a spacerframe relating to a slit for sim holder in it | 06:32 |
houkime | however, it needs to cut into a case to have an orifice for simcard low enough, it is all in the docs. | 06:33 |
houkime | So if we put a mic on S2 instead of, say, bottom surface of UPPER | 06:33 |
houkime | mic will be facing not spacerframe but mostly a case wall. | 06:34 |
houkime | which is a case in the current sch. | 06:35 |
houkime | even more interesting thing is with the "scrutiny LEDs" | 06:35 |
houkime | They are also supposed to be on S2 near spacebar area but will face a case. | 06:36 |
houkime | there is spacerframe a little bit higher but they will be facing the case. At least it seems like based on simsw,pdf | 06:37 |
houkime | *seems like it | 06:37 |
houkime | nap. | 06:37 |
Joerg-Neo900 | you're right. You found a "bug" there. for mics we either drill/cut a hole or get a slot of 0.8mm width and a few mm depth into UPPER | 06:44 |
Joerg-Neo900 | for LEDs we need to review | 06:45 |
Joerg-Neo900 | spacer frame has a rim that goes a bit further down to S2 than the edge of black plastic case | 06:45 |
Joerg-Neo900 | good find | 06:46 |
Joerg-Neo900 | btw same for fancy LEDs as well | 06:47 |
Joerg-Neo900 | scrutiny LEDs are actually not that big an issue, they are meant for the hackers and the paranoid, those will have no problem modding the black shell to see them. Regular users might rather feel annoyed by the scrutiny LEDs | 06:49 |
Joerg-Neo900 | btw I almost managed to get 30% of my WS system running again | 06:50 |
enyc | Joerg-Neo900: hooray =) | 07:37 |
Joerg-Neo900 | bbl, 42.3 -> 15 | 11:03 |
houkime | ok NOW all 3 boards + adapter are correctly separated and don't have common nets. | 17:22 |
houkime | beautiful, but still a mess. | 17:33 |
enyc | houkime: i think the world is a mess ... | 17:41 |
houkime | for world it is ok to be mess. You can;t put people to order really and I believe with some technical progress towards autonomous space dwellings it will be possible to be both government-less mess and prospering civ. | 17:44 |
houkime | but neo900 should be in order and beautiful | 17:44 |
houkime | ^_^ | 17:44 |
houkime | Joerg-Neo900: what is with a moster -through-hole testpoint for BQ_PGM (TP301)? | 17:57 |
houkime | is it needed so large? | 17:57 |
houkime | I remember I swapped some tp-s from through-hole stuff to usual ones back then | 17:58 |
houkime | probably forgot one | 17:59 |
DocScrutinizer51 | BQ PGM is high voltage programming | 18:02 |
DocScrutinizer51 | the larger it is the safer and simpler programming in a lab in testrig | 18:03 |
houkime | ok, so it needs to be like that. Ok, one more sacrifice to the ancient fuel gauge. It is both sides too... oh. | 18:04 |
DocScrutinizer51 | shrink as you think is needed | 18:05 |
DocScrutinizer51 | it's no religious dogma | 18:05 |
DocScrutinizer51 | prolly nobody ever will want to program bq27200 | 18:05 |
DocScrutinizer51 | maybe you find a nice otherwise useless free space for placing TP, e.g. under SIM holder in a hole or window of holder | 18:08 |
houkime | what are the frequencies of high-voltage programming | 18:20 |
houkime | ? | 18:20 |
DocScrutinizer51 | DC | 18:20 |
DocScrutinizer51 | iirc +9V | 18:20 |
houkime | checked datasheet it is a 21v pulse | 18:31 |
houkime | rises and falls are 21 v per 0.5 - 1.5 ms | 18:32 |
DocScrutinizer51 | errr | 18:33 |
DocScrutinizer51 | well, 1ms is almost DC ;) Anyway I thought the programming was via I2C and the Vpgm was only needed as long as flashing happens | 18:35 |
DocScrutinizer51 | no need to pulse it, I might be wrong | 18:35 |
houkime | Pulse seems to be a single time thing (length 10-100 ms) to enable pgm state. | 18:36 |
houkime | electrically edges are sth like 20-40-ish kHz equivalent for 1v8. Not much. | 18:38 |
Joerg-Neo900 | bq27200 indeed needs a ~50ms pulse of 22V on PGM for each of the 10 bytes | 19:36 |
houkime | condensed this into issue for future use https://notabug.org/Houkime/Neo900-Issues/issues/12 | 20:23 |
Joerg-Neo900 | THE fSCK, I've set konqueror as default browser but seems in suse15 some of my minetypes or whatever are totally messed up, andway when I click this URL, I have a 200 konqueror windows after only 15s and my only chance is ctrl+alt+F1 log in as root and killall konqueror | 20:43 |
Joerg-Neo900 | konqueror <thinking>: "HUH I'm smart, I got a file here and it looks like HTML, so let me see what the app for rendering HTML is. AAAH it's konqueror so let's invoke it" | 20:45 |
houkime | currently using falkon(former qupzilla)+pcman-fm-qt. Never used konqueror. Funny effects of having fm and a web browser as a single app. | 21:12 |
houkime | programs that are trying to bee too many things at once is a receipt for disaster i guess. | 21:19 |
atk | kitchen sink design | 22:08 |
Joerg-Neo900 | well, konqueror uses plugins, so it's just (literally) a frame and arbiter around most stuff | 22:11 |
Joerg-Neo900 | actually I think Firefox "does more" a lot, than konqueror core | 22:12 |
Joerg-Neo900 | e.g. konqueror has no own form varables and passwords store | 22:13 |
Joerg-Neo900 | FF does | 22:13 |
Joerg-Neo900 | konqueror usually used wget for download. Firefox download is built in | 22:14 |
Joerg-Neo900 | err kget | 22:14 |
Joerg-Neo900 | same with pdf, svg... | 22:27 |
