**** BEGIN LOGGING AT Fri Mar 23 03:00:04 2018 Mar 23 05:13:27 Hmmm Mar 23 05:13:57 m_w I was looking at pmezydlo's board, but some of the libraries used were not included (db9, 24c512,23x2 connectors etc) Mar 23 15:45:01 Pac23: Did you find about PRUDAQ ? coz its going to be a big deal and needed to be figured out and detailed in the proposal. Otherwise the project might yet again get stuck in the hardware-cycle. Mar 23 15:46:38 @zeekhuge yup Mar 23 15:48:53 although my project doesn't relly much on the prudaq except for some part of it so i dont see the hardware-cycle kind of thing happening. Mar 23 15:49:44 you might find this useful there are links at the bottom that explain things in detail like its performance,how to modify it etc Mar 23 15:49:49 https://github.com/google/prudaq/wiki Mar 23 17:06:01 jkridner: please provide feedback for the proposal Mar 23 18:12:57 @abhishek can you guide me more about the prudaq ? i have read the wiki on github but more info would be welcome Mar 23 18:14:00 what project are you proposing, Pac23? Mar 23 18:14:29 @ds2 anemometer/weatherstation Mar 23 18:15:06 much of previous years work relies on the prudaq Mar 23 18:15:12 ah that project Mar 23 18:15:27 what aspect are you trying to tackle? Mar 23 18:16:59 i am going to aim for finishing it for once since for the past two years(2016,2017) this has been proposed but never reached what i should be,i am going to tackle the additional sensors and remote deployment part + front end data generation Mar 23 18:17:11 get a working prototype ready Mar 23 18:17:44 okay, how are you proposing to do that? I was involved in that Mar 23 18:17:55 new HW? Better algs? Mar 23 18:19:55 yup additional sensors,for gas,barometric pressure,humidity,better temperature sensor that offer more control Mar 23 18:20:51 what kind of sensors are you thinking of? Mar 23 18:21:24 MCP9808 High prescision Temperature sensor Mar 23 18:21:24 CCS811 High prescision Air Quality Sensor Breakout - VOC and eCO2 Mar 23 18:21:24 BMP180 Air pressure sensor Mar 23 18:22:43 and a sma 800/900 module for cellular Mar 23 18:23:02 so that the weather station can be deployed remotely Mar 23 18:23:43 my elinux draft is https://goo.gl/Tmh8Jk feedback would be appreciated Mar 23 18:24:19 uh... few questions: 1) How does this relate to the annometer? 2) What exactly are you hoping to get from the CCS811? 3) Why are you using the CCS811/BMP180 instead of a BMP680? 4) Do you know what the CCS811 really measures? Mar 23 18:26:11 so you are proposing a weather station? Mar 23 18:26:23 yeah Mar 23 18:26:38 its supposed to be a anemometer + weather station Mar 23 18:27:04 yes i have done a bit of reasearch on the ccs811 and compare it to the bosch680 Mar 23 18:27:34 the thing is the *BMP680 can't differentiate between stuff Mar 23 18:27:47 eh? the CCS811 can't either Mar 23 18:27:48 whereas the ccs811 can Mar 23 18:27:56 it outputs a TVOC number and eCO2 number Mar 23 18:28:24 the eCO2 number can be absurd when compared to a real CO2 sensor (i.e. NDIR based) Mar 23 18:29:01 yeah but the BMP680 only gives one value Mar 23 18:29:04 depending on the TVOCs present you can read 4000ppm eCO2 which would be very bad if you read the wikipedia page Mar 23 18:29:20 *bme680 Mar 23 18:29:42 yes, but the eCO2 number is pretty useless for most purposes besides HVAC Mar 23 18:29:57 where are you geographically located? Mar 23 18:30:10 i have mentioned the bme680 as a optional thing in my proposal thank you for the heads up i did'nt really know this thing about the ec02 :-) Mar 23 18:30:24 i am located in a major city with heavy pollution Mar 23 18:30:28 mostly motor traffic Mar 23 18:30:44 but there's swamp all around me Mar 23 18:31:02 https://en.wikipedia.org/wiki/Mumbai Mar 23 18:31:31 ah... donno how easy it is to get but the SiLabs Thunderboard or a Nordic Thingy has a CCS811 in it Mar 23 18:31:40 that way you can get a feel of what it does or does not do Mar 23 18:32:50 afaict, the CCS811 is basically a tweaked SnO2 sensor...it;'ll react to many things Mar 23 18:34:05 sry to interrupt, but maybe also consider that the ccs811 has a driver in mainline iio, while bme680 doesn't. I never used it, so i don't know if it does everything that you want Mar 23 18:34:11 for general pollution monitoring, it'll probally be fine but that puts you back into the BME680 range Mar 23 18:34:16 so what exactly do you recommend give the environment around me ? this is why i put in the bme680 as optional because that thing does the job of three other sensors Mar 23 18:34:48 @hgonzalex the bme680 has a python module so there's that Mar 23 18:34:48 hgonzalez[m]: it is I2C... easy enough to put together a driver...prehaps upstream it :D Mar 23 18:35:23 yeah, it is one of the linux foundation gsoc projects, add channels for everything on the me680 Mar 23 18:36:18 Pac23: let me aanswer that in 2 ways - personal interest wise, I'd go with a the 680 unless it is a sourcing issue; gsocwise- I question the overall project... focus on cleaning up and making the annometer reliable may make more sense Mar 23 18:36:43 Pac23: I just like staying in the upstream, don't want to bother :) Mar 23 18:37:59 another tangental comment is - I wonder if these sensors really belong on the BB... from a power standpoint, it seems suboptimal. Pair them up with a small processor and have the Bone link to it over RF Mar 23 18:38:14 that way the sensor can be run on a few AA's or solar Mar 23 18:38:31 but that's outside of the scope of GSoC :D Mar 23 18:38:58 So, i wanted to say that a proposed a project, I don't know if I have to let someone know: Mar 23 18:38:59 https://elinux.org/BeagleBoard/GSoC/Port_am335x-pru-package_to_remoteproc_-_GSOC_2018 Mar 23 18:39:07 i have mentioned the solar part,but pairing them to a small processor sound nice Mar 23 18:39:45 @ds2 idk if i am asking too much but an you please expand little bit on cleaning up and focus on the anemometer part Mar 23 18:40:23 Pac23: the anemometer barely works as of last year Mar 23 18:40:34 think that is enough said :D Mar 23 18:40:47 there are 2 days left and i want to get my proposal all good to go by tomorrow morning if possible,i dont want to get rejected Mar 23 18:40:50 i forgot what the HW we settled on was... Mar 23 18:41:30 okay i will look into this and change accordingly,thanks :) Mar 23 18:41:33 has any mentor agreed with your proposal? I'll probally not be working on that this year Mar 23 18:42:06 hgonzalez[m]: reading it.... Mar 23 18:42:25 i have discussed it with @wormo she and @nerdboy are the mentors,i have been told to make some changes Mar 23 18:42:49 i have also tracked down the person who worked on it last year and contacted him today regarding this Mar 23 18:43:08 we are going to discuss where things were left of tomorrow Mar 23 18:43:45 'k Mar 23 18:44:47 hgonzalez[m]: have you see: git://git.ti.com/pru-software-support-package/pru-software-support Mar 23 18:44:48 -package.git Mar 23 18:45:45 yes, i have. I tested some examples using that Mar 23 18:46:00 how is what you are proposing different from that? Mar 23 18:46:44 thanks for the advice @ds2 Mar 23 18:46:56 not really different, but it was in the projects ideas. thought it had some value for the community Mar 23 18:47:30 hgonzalez[m]: I recommend figuring an answer to it Mar 23 18:47:45 I reckon the project was proposed last year too, maybe it's obsolete. As the PRU DMA is and it's still showing Mar 23 18:53:53 pru dma was to create examples to use dma...that ahs been done, AFAIK Mar 23 18:54:12 there is a next step - use the pru bits and create a "soft peripheral" example Mar 23 18:54:49 i.e. create a SPI master interface on the PRU and expose it through the spi subsystem... goal here is not writing that code but rather to provide an example Mar 23 18:55:16 an ambitious example would be to use the PRU as a video capture interface and expose it as a v4l2 interface Mar 23 19:01:58 Yes, i also wanted to propose sth on that line, but I tackled this one first. Mar 23 19:03:03 Will dig more on that then Mar 23 23:56:49 jkridner: cwicks: Wormo : Mar 23 23:56:50 https://elinux.org/BeagleBoard/GSoC/ProposalTemplate#Modern_.22Speak_.26_Spell.22_using_Pocketbeagle Mar 23 23:56:51 Please take a look at my proposal and suggest me any improvements. Mar 24 02:18:52 m_w: is there anything more I can change in the proposal? Mar 24 02:25:21 And for the final proposal are we supposed to export the wiki page as PDF and upload to summerofcode? **** ENDING LOGGING AT Sat Mar 24 03:00:01 2018
