Bertl: A quick FPGA question if you are there - I see a timing constraint file for HDMI -
00:21
danhanes
but I cannot find a reference to HDMI IP. Is HDMI implemented yet ?
00:22
Bertl
yes, what sub-project are you looking at?
00:22
danhanes
axi3_hdmi
00:23
Bertl
okay, hdmi configuration is done in userspace
00:23
Bertl
the FPGA code connects the analog devices HDMI encoder via i2c
00:24
Bertl
and it sends the actual sync and data
00:24
danhanes
Ah - that helps. It is slowly seeping in
00:25
Bertl
scan_hdmi generates the signals
00:25
Bertl
I will change that a little soon, because I found a simpler way to handle the scan generator
00:26
Bertl
but the basic concept stays the same

danhanes
Yes, I think I see. More study.
00:27
Bertl
no proplem, don't hesitate to ask if something is unclear
00:27
danhanes
Thanks. This is taking longer than I thought, but progressing steadily.
00:28
danhanes
I suppose I should look at the Zedboard schematic more closely.
00:29
Bertl
it helps, especially with HDMI, they screwed up big time there :)

On a somewhat related note - is there any open source SDI vhdl out there?
00:31
danhanes
The Xilinx IP costs real $

I've seen that there is one from Xilinx bundled with ISE, but I haven't checked under what license
00:35
danhanes
Well, I guess that is an issue for the future. I'm partial to 6G SDI at some point.
00:36
Bertl
but we did AXI Master/HP Slave, SPI, Video Scan Generator and many more already, so I'm not that afrain of SDI :)
00:36
danhanes
There seems to be adequate talent...

guesst
Bertl : we have used the Xilinx SDI core, but it is not a core.. just an SDI encoder/decoder. streams have to be constructed on ones own
07:38
guesst
basically it is a scrabler

Fun times.
16:07
troy_s_damn_ghos
So Bertl - some noise success?
16:07
Bertl
I'd say so
16:08
troy_s_damn_ghos
Did Gabe make any progress on the profile?
16:08
Bertl
the main problem with noise is that cmosis is somewhat uncooperative in this regard, so classification requires testing and trying out a few things
16:09
Bertl
but over all there is steady progress

Hola

got issues with quassel recently too
17:04
Bertl
connection reset and ping timeout sound more like provider issues
17:06
troy_s_damn_ghos
I am flip flopping wireless etc currently
17:06
troy_s_damn_ghos
Previously it was provider or something

Is there a recommendation for a free CAD program that works on OSX?
19:27
Bertl
googling for 'cad free osx' yields quite a number of hits, the first one being librecad

Alright thanks, I'll go that road. I thought somebody might have gone that way already and tried a few, thus being able to recommend one.
20:41
danhanes
shinokubo: I downloaded and installed the OSX version of Eagle a few days ago. It works OK.
20:41
danhanes
Not the greatest CAD, but unfortunately better than KiCAD for now.
20:42
Bertl
eagle = pcb layout/schematic tool, not necessarily cad (depends on your definition of cad)
20:42
danhanes
right - I assumed ECAD

thanks danhanes, I went for freeCAD. I want to CNC-Mill some small aluminium parts. Most of the things talked about in here are new to me, but I'll try my best.
