* BAndiT1983:

Can I add a new recipe in the existing makefile itself ?

by the way, why are there often 2 long messages from you? something wrong with your client?

<BAndiT1983 "by the way, why are there often "> can you send a screenshot, I am using element.

http://irc.apertus.org/index.php?day=17&month=03&year=2021

no

element supports that

are they required and used somewhere?

you can add it, if they are required, otherwise i don't see a necessity at the moment, as the challenge task is about 2bit icons, to smooth them out, so they will be probably replaced when this new feature is done

does your irc render emoji?

the makefile is broken, `convert -density 200 $(TEMP_DIR)/TempRocket.svg -trim +repage -filter point -monochrome -resize 200x200 xbm:- | ./convert_xbm_to_h.sh $@ -`

magick apparently isn't shipped as a binary

it depends on the system one is using, as the makefile was tested i doubt that it's broken

my system (manjaro) understands both fine

as the CI container uses ubuntu, it was building just fine, so maybe something changed in-between

convert is a symbolic link in the newer version, maybe you need to check how old your IM is or maybe ubuntu has some own flavour, that's why i stick to manjaro for a couple of years (linuxmint before)

good morning

<BAndiT1983 "vedant16: looks like magick is t"> I'll update my version

hi BAndiT1983, great to see so much activity here vedant16[m]!

printing aluminum like a normal FDM printer does

Hi se6ast1an_ I am working on the qualifying statement :)

interesting, maybe i can modify my prusa ;)

<se6ast1an_ "printing aluminum like a normal "> woahh, this is nice

in this function, color means the color of the pixel to be displayed, so what color codes should I use for the 4 colors in 2-bit pixels ?

transparent, light grey, dark grey, black. I'll use ascii codes for these

just found utils.h, I'll use RGB565 function

please elaborate

yes, i know that, but how should it help in the firmware?

<vedant16[m] "just found utils.h, I'll use RGB"> I was just being verbose, and then I found this function

haven't found suitable conversion in IM, as the .h one is rather rudimentary

<BAndiT1983 "what's the most important topic "> Yup, imagemagick one doesn't work. I'll use a .h for now

something very strange

see the extreme right column ?

you can see a diamond there

yes, it's normal, as values change for every pixel, so you can see the image in the file map, what is your trouble regarding that?

but the general image shapes can already be easily seen

we just need a proper compression of 4 pixels into 1 byte, 2 bit depth, so the expected values are from 0 to 3, where 0 is transparent and 3 opaque

<BAndiT1983 "would suggest to grab smaller pi"> ohk, will do that

good day!

vedant16[m]: in fact it's almost good evening here ;) just joking ist 13:46 (CET)

<BAndiT1983 "vedant16: in fact it's almost go"> It was actual evening here (IST) when I replied, it was 6pm xD

vedant16[m]: i know, we had many students from India, so learned to take the time shift into account

Also vup can you brief a little on how the current load of the camera can be made accessible to the frontend for the task 2?

mohitdmak: do you mean processor load?

found around 6-10 ways how to get the load in the terminal, as far as i've understood you're already grabbing the wifi networks from NetwrokManager, so it should work in similar way

Thanks though :)

you should look around linux first, but that's my opinion

Hi, I have forked&cloned the repository and able to run the project locally in my system. Also, understood the flow of the project. I am focusing on task 1 of the challenge ( fancy wifi list ). So what my understanding is that currently simple HTML table is being used , you want it to be replaced with more beautiful table may be material-table which has the sorting functionality based on different keys. Wifinetworks key in state contains the data

Please correct me if I am wrong.

@vup is my understanding correct ?

also one should think about which side of the communication, host or client, needs to do what in the process

https://github.com/VedantParanjape/AXIOM-Remote/commit/a66c637e201ecbdab801a1727e5dee42ceec3b1f

I still can't figure why image is getting cyclically rotated.

which coding guideline are you following there? -> color_map

how is the image behaving on different backgrounds? e.g. balck, white, gray?

<BAndiT1983 "how is the image behaving on dif"> not tested yet. lemme do that

umm, the right hand is getting displayed on the left

<BAndiT1983 "which coding guideline are you f"> sorry, updated

vedant16[m]: The drawing origin (X,Y = 0,0) is located in the top left corner, do you also read the image pixels from top left?

I read sequentially, used lvgl.io's image to .h convertor

like starting of array is the right most pixel

as we haven't written the converter, we don't know, it was listed as example and starting point, our overal goals ragarding that topic were listed by me today before

That converter doesn't work properly

<markus_ "That converter doesn't work prop"> ohhh

I wrote my own in Python instead, I can link to my repo in a second

like i said, the converter was listed as reference, but we expect that students provide some solution which fits the task and is maybe suitable for automation, like calling from the makefile

I had a question regarding coding style.

Since there was a link to the isocpp faq in the challenge

so should I prefer using std::array or just plain C-arrays?

you can see the style in the firmware code, but it should be mainly C++ style, so pixelData and not pixel_data

markus_: generally you should keep in mind, that it's a pic32 MCU, so C++11 or similar, are not that much possible, but to some extent

alright I see

thanks for testing and verifying the online converter doesnt work, I removed it from the challenge description

probably, but not for us :)

of course, as i can't automate that in the CI build

https://stackoverflow.com/questions/8707183/script-tool-to-convert-file-to-c-c-source-code-array

xxd does a great job

markus_: you can test it with XC32, it shows nice memory summary for the build, also cutter/radare2 can help to disassemble the resulting ELF file, to check the sizes and sections

<BAndiT1983 "vedant16: how do you want to con"> image magic -> xxd -> sed

alright, looking forward to it, but don't forget that it needs also width and height info, maybe also format info like 1 bit or 2 bits

python with PIL and templating was not that difficult also, have created a template file with placeholders, python can substitute them easily, just as a tip

I was thinking of a very minimal solution

manual way is also possible, am just having quite some tasks at work regarding CI/CD, so automation is my focus

ohk, then I'll go forward with python

vedant16[m]: didn't want to stop you from your plan, am just giving advices regarding possibilities

as we have some python for the remote programmer and in the future probably a mock service to mimic the camera, so it's one of possible things to use

this is only for passing in the 4 colors to be used btw

in the favor of c-arrays and pointers

markus_: which task do you target, by the way, just so we can keep the track of which tasks students want to do, firmware or bootloader?

alright, thank you

but you can also use the 4 values, although just 2 would be needed there, for calculations, haven't done any prototype yet, usually i create one for gsoc to compare against the student challenge code and often learn new things and ways

no problem, just mentioning it, the goal is also important, but the challenge is mostly about how students integrate and collaborate in the project, also the code style is bigger factor

lambamansha: If you read the log: Yes there are several ways the wifi display could be improved for example making the table more beautiful, by using the material-ui table, highlighting the current IN-USE wifi network or showing the SECURITY values using chips. Be creative :)

Hi,yea its like a charm,I had logged in from two devices (mobile and laptop) so just loging out of phone to have just one account..

awesome, btw there is also a quassel app for android (and for ios aswell I think)
