Bertl_zZ: I look at the mDP thing on the weekend, it was at the stage of trying to figure out the pin outs

morning folks!

good morning

Bertl
mithro: okay, tx
09:04

Bertl: As you have the axiom side done now, it makes it easier to finish the Opsis side, most of the were I was stuck was figuring out how to balance Opsis<->axiom verses Opsis<->Opsis verses axiom<->axiom using the same design
09:05
Bertl
the question is, if it wouldn't be simpler to make an Opsis -> Axiom 2x PCIE-36 adapter
09:05
Bertl
because then all the AXIOM Plugins can be used, including the 3xmDP one
09:08
mithro
Bertl: that is what I was wondering

Bertl: Can you take a look at the following? https://docs.google.com/spreadsheets/d/15rivtOcSG4kqKf0AUK_OwBfs67XQtW8byr8kc5FUTgE/edit#gid=1654125645
12:10
mithro
Bertl: if the ""apertus pins mapped to TOFE header" section looks okay, it should be pretty trivial to finish off doing a Opsis->Axiom adapter
12:10
mithro
Bertl: the hard part is the mechanical design....

hi all
12:13
Bertl
mithro: the only difference I can see on the AXIOM pinout is that VCC should be N_VCC and S_VCC as they can differ
12:13
Bertl
(similar with V_I2C -> N_V_I2C and S_V_I2C
12:13
Bertl
)
12:14
Bertl
but that should not matter for an adapter, you can supply both with the same rail
12:15
tyrone
hey bertl i have a small question, at the embedded world you said it would be nice to have a pcb/gerber viewer whats the main target rendering in blender or webgl viewing?
12:15
Bertl
both would be nice of course
12:16
mithro
Bertl: have you seend http://gerblook.org/?
12:16
tyrone
and other wishes? a six pack of beer? :-)
12:16
Bertl
personally I'd say webgl is more important as long as we can produce some STL (or similar) which can be imported into blender + co
12:16
Bertl
tyrone: world peace please :)
12:17
mithro
s/seend/seen/
12:18
tyrone
ohh thats a easy task :-D
12:18
Bertl
mithro: no, not yet, what does it take as "gerber files"?
12:18
tyrone
backend wise is it okey when you need some backend software? or only javascript?
12:19
mithro
Bertl: yes
12:20
Bertl
"yes" is as helpful as the page, it doesn't take zip or tar.bz2 archives, so much I already know :)
12:21
Bertl
always says: couldn't find top soldermask layer
12:22
Bertl
same with individual gerber files, I guess they have to have a special names
12:26
Bertl
tyrone: what do you mean by backend?
12:28
Bertl
note that it is fine if it is a conversion, i.e. you input board designs, part libraries, 3D models (parts) and then run some tool which makes nice 3D models of the entire PCB
12:28
Bertl
the "model" then can be used for blender or webgl (so the idea)
12:32
tyrone
there are two ways todo make the complete conversion from gerber to mesh data in javascript runs in the webbrowser second one should be a smaller tast use on the server some software (Kicad) that loads gerber and creates 3d mesh(stl or obj) and load that data on the web viewer.
12:32
tyrone
tast -> task
12:42
Bertl
well, in general, the gerber data is not sufficient
12:43
Bertl
it does the trick for unpopulated boards but not for populated ones
12:43
Bertl
you need at least some kind of placement data/list and 3D models for the parts
12:47
tyrone
i was thinking to use kicad in the backend so i don't have to deal with all the file formats and try to get the best output format or create a custom export. i have seen something of a obj export but i'm not sure if it's still working.
12:49
tyrone
small offset question the axiom beta the module slot are they pmod compatible? (when there is a adapter board of cause)

12:53
Bertl
you can see the Triple PMOD Dual Slot Plugin here
12:53
Bertl
no idea why it isn't on the wiki yet, se6astian?
12:54
Bertl
or maybe it is and I just can't find it :)

12:54
tyrone
ahh cool just haven't seen it :-)
12:56
Bertl
we even used it at the last Linuxwochen for HDMI output :)
12:56
tyrone
because of your idea with the storage system i haven seen this: http://store.digilentinc.com/pmodsd-sd-card-slot/ and there are so many other modules....
12:56
Bertl
https://www.apertus.org/sites/default/files/GEZ_2594.jpg
12:56
Bertl
yeah, we also had some PMOD modules from the Alpha, so it was one of the first plugin modules to create
12:57
tyrone
nice :-)
13:02
davidak
the original with the pink cable :D
13:03
Bertl
more interesting are the two I2C pullups in the MicroZed PMOD header :)
13:03
Bertl
(which we had forgotten on the PCBs back then :)
13:06
tyrone
well at least i know now you are not 100% perfect..... :-)

Bertl: I thought the gerblook person had merged my change which made it find kicad output automatically...
13:49
Bertl
well, I tried the gerbers I made for OSHpark, and they are not understood
13:49
Bertl
but I found the patterns in the FAQ :)
