#apertus IRC Channel Logs

morning folks!

good morning

This channel is not very lively :(

https://twitter.com/cinema_open/status/725255085496799232)

that looks like a nice adapter

I see that there's discussion for adapters in the tweets

all soviet glass uses either a twist-in bayonet, or a very large but standardized metric thread

M42 is just a metric 42mm inner thread with a step/lead of 1mm(m42x1), M39 is the same, just m39x1.

Good info.

Hi Sebastian :-)

OK, soweit so gut ;-)

also, the channel is logged :)

So, I am successfully logged on.

do you have another monitor around

those so far proofed to work in most cases with the beta signal

no the ninja does not support 1080p60

Rebooting now.

Trying now…

I am supposed to use the port next to the green light, right?

Hi Alex :-)

AC7

Bottom HDMI is the one opposite the ethernet port?

OK.

:)

the correct nomenclature (which is a little confusing) is 'south' plugin slot

yep

two short pulses, pause, rinse and repeat

the green one is always on and when you are acquiring a picture the blue one will flash

The real question is, are the blinkenlights controlled by the FPGA or the ARM cores? :P

the blue one by the FPGA

Can I just pull out the card and use the other one?

but note: most PC monitors cannot handle 1080p30 :)

Did not work.

I will try a different HDMI cable.

I confirmed it just yesterday with my regular camera, switched output from 30p to 60p

weird

TVs are fine with anything you throw at them

unfortunately not

Is there a command to test board to sensor communication?

Yes Bertl.

so the blue one is flickering too?

are you logged into the Beta?

Yes.

try ./kick_manual.sh

so you already messed up the filesystem :)

what does the following give you:

BTW, the system hung after: S_VW 1.9531 V [ c80] -0.0391 mV [fff] -2.60 mA

yeah, that is kind of expected

Oh man!

btw, there is a reset button on the MicroZed (JFYI)

that's the other one

so that doesn't look completely wrong

both are blue, IIRC :)

yup

AndrewIsback: let's check with:

lrwxrwxrwx 1 root 16 Apr 27 15:47 cmv_hdmi3.bit -> cmv_hdmi3_30.bit

-rw-rw-r-- 1 500 2148463 Oct 24 2015 cmv_hdmi3x.bit

-rw-rw-r-- 1 500 2193379 Oct 26 2015 cmv_hdmi3z.bit

jan 1 1970

sounds wrong

Yeah, 1970…

wait, was it generated on the microzed?

yes

AndrewIsback: but they can be added easily

nevertheless, I suggest you get the networking up and running first

Is there an FTP server running?

OK

but sshd is running, so once it gets an IP, you can simply scp files over

How do I generate a public key?

Which file should I save it to?

In the session.

Maybe "/root/.ssh/authorized_keys"

you want to generate it on your PC

OK.

Generating it on my Mac.

Is that location good: "/Users/andrew/.ssh/id_rsa"

OK, I generated it.

Now how do I move it?

run cat >>/root/.ssh/authorized_keys

then copy/paste the key data

I got a line that starts with "ssh-rsa"

OK, did that

where <beta-ip> is the IP address the Beta got

then you made a mistake with copy/pasting the key

and cross check it with the one you generated

Bugger, it is different at the very end.

well, your copy/paste seems to be weird :)

anyway, you can edit it manually as well

yep, vi :)

yep, run:

type SHIFT-G

do you want to try to copy it in small pieces?

Or just scroll to the end…

which will put you into replace mode

OK

OK

: will put you in command mode

and x is the 'save' command

after that, check with the tail command

what?

ESC will end the paste mode

When I type x the last character is deleted

you want to press ':'

Ah!

Terminal

So, saved it…

It appears so.

nice

does ping 8.8.8.8 work?

Yes

oh... wifi

10 packets transmitted, 10 received, 0% packet loss, time 9013ms

The Beta is plugged into my router.

Working

ls -lga cmv_hdmi3.bit

It#s there now

maybe, let's do:

back

I see you are still fiddling :)

AndrewIsback: good, only problem is, that's the _60 version :)

Sounds faster :-)

Moved it

ln -s cmv_hdmi3_60.bit cmv_hdmi3.bit

Linked

e.g. with cat kick.sh

Yes

No

OK

OK

OK

./gen_init.sh 1080p60

okay, that means it is configure for PC monitor

now let's do:

so that we do not lose any data :)

and run ./kick_manual.sh again

Flashing blue!

\o/

it was, wasn't it?

How do I stop the transmitting?

Or do I just unplug the power?

you can run halt_manual.sh

shutdown -h now

*the

What could not halting it cause?

filesystem is log based, so normally it doesn't do anything

but if you are very unlucky, you could lose your latest data

probably, but you also need to download the 30FPS firmware

do some cooking, I'll see that we find a copy for you

I'll be back soon.

bbl

wb :)

Managed to replicate the key thingy on the laptop that I'll be taking to demonstrate the Beta in Berlin :-)

http://vserver.13thfloor.at/Stuff/AXIOM/BETA/cmv_hdmi3_30.bit

An :-)

Bertl, what's the difference between the 30 and 60 firmware?

one does 1080p60, the other 1080p30

it is only PLL settings, so they could be changed at runtime

why not implement the DMA communication between the two?

OK, installed it.

Don't want to ruin my fine file system :-)

I accidently rm -rf *'d a production server once

now I re-read the input command 6 times before I press enter

how is the bitstream loaded into the FPGA?

Press the little blue button?

ReSeT?

woaahh, Spirit532, that sounds awful (the production server thing)

I had a day-earlier backup :P

shutdown -r now

Andrew: all your questions are really great, i've made a note to answer them in the documentation

the important part for documentation though is to wrap it in such way, that it isn't a cooking recipe

though the Beta is very far from a manual right now

so I see two options there: 1) add a version number to each recipe

The Ninja 2 does not recognize the HDMI stream.

Can I check the FPS?

nah, not dumb user(s), but the camera should also be usable by non-nerds/non-techies (:

OK, that was in the shell script, right?

and remove the # from the SHOGUN line

# ./gen_init.sh 1080p60

Can I get some vi help please?

A tiny FTP server would make this kind of thing much easier.

i find vi(m) simpler (;

kaiserlich: it is actually vim

although I'd suggest to make a backup of your SD card first ;-)

for editing a file with vim, you'll have to first press i for INSERT

and to exit it again, press ESC

'i' is insert, 'r' is replace

http://vim.rtorr.com/

OK, fixed the script

Mental note: study vi commands :-)

Nice!

so, test with another reboot (shutdown -r now)

the most basic commands in vim really are i for the insert mode, then ESC for exiting the insert mode (so a lot of times, you will switch between the two) and then the colon followed by a letter, the most important of which are :w for writing, :q for quitting... :x is the two combined (i.e. saving and quitting)

whenever i accidentally nano things, i never know how to quit it again

ctrl+c N?

or ctrl+x N/Y

anyway, I'm not suggesting that everybody uses vi

Andrew_has_fed_h: run ./cmv_perf3

29.95 FPS

Looks right

Yes

./rf_sel.py A

Yes!

does the picture look okay?

Have to attach a lens…

lol

It's quite dark,

Yes :-)

e.g. with ./cmv_snap3 -e 50ms -z

yes, please

can you upload it somewhere?

or is that a problem?

Filming the screen I could create some moiré.

The two audio meters are like stuck in front of the logo.

And the border is only visible only top and right.

okay, but that seems to have everything as it should be, no?

Yes.

so it is the display on the ninja which cannot handle the full HD

Looks like it.

but the fact that it is recording the full overlay means that it understands the signal just fine

Here is the snapshot: ./pic_jtag_pcie.py 0x92 0x92

https://drive.google.com/folderview?id=0B23tS9bIjRt6R2o1T3JTRkNjRlk&usp=sharing

you might also want to move the logo to the right, if you want to have it

./mimg -a -o /opt/IMG/overlay_04.rgb

Thanks Bertl!

Exploring all the aspects will be FUN :-)

How does that experimental RAW recording work? Is there a page for that yet?

doesn't work with p30

Bertl, is the unit Andrew has a developer unit sent on schedule, or something special? He mentioned showing it in Berlin.

I see

I'm not sure if it's usable for this thing but I will be very happy to see a raspberry pi in a axiom camera :)

yes right ! :)

the SATA board will give you speeds up to 50MB/s

each SD card in the AXIOM Beta (there are two of them) can do 25MB/s

but if somebody actually builds an HDMI in addon for the RPi which uses the proprietary camera interface, then it would be possible to do 3D GPU magic on the AXIOM output on the RPi

note that this was already attempted but failed.

IIRC, with an older model

*raspberry pi 3

I am off to bed cave!

Rex0r: how's that?

You're clever lads.

admit it, you are just jealous :)

Well, yeah, but it's the financial outlay that makes me realise how lucky I am. Bills at the hair cave must be horrendous.

off to bed now ... have a good one everyone!

nn

Alex_Chooks: which RPi can do 4k on hdmi ? the pixel clock is limited to 165MHz.. so are you talking about 4k at 15Hz? :)
