| cr1901_modern | mithro: You need me to create a freq counter, but the minispartan6 currently does not use the HDMI2USB core. Should I wait for shenki, or just try to brute-force support for now? | 00:04 |
|---|---|---|
| cr1901_modern | wait for shenki* to finish the port | 00:04 |
| mithro | cr1901_modern: You should be able to do everything independently | 00:05 |
| mithro | In terms of urgency, I need that frequency counter stuff yesterday too... | 00:06 |
| cr1901_modern | So did you implement it yourself? Or do you not need it anymore? | 00:06 |
| mithro | cr1901_modern: No, I haven't had the time yet | 00:06 |
| cr1901_modern | Alright, let's see what I can do. | 00:07 |
| cr1901_modern | It can't be THAT tough to add a freq counter. You just need me to add two CSR registers and some defines for it, right? | 00:08 |
| mithro | cr1901_modern: well, I think we want a little more then that - but probably a good start | 00:08 |
| cr1901_modern | mithro: Why do you think that I can do everything independently? The BaseSoC doesn't have HDMI support? I mean, sure I guess I could write something that sniffs the traffic, but I assumed that you already had gateware that handled being able to extract data from HDMI streams (or at least split it). | 00:12 |
| cr1901_modern | Doesn't matter I guess; I mean, I have the warmcat article open | 00:12 |
| mithro | cr1901_modern: yeah - you only care about the two vsync/hsync pins | 00:12 |
| cr1901_modern | I hope my computer isn't "too smart" and doesn't try to stop sending data when it doesn't actually detect a valid monitor lol | 00:13 |
| mithro | I think we can start with number of cycles the pin is high and number of cycles the pin is low? | 00:16 |
| cr1901_modern | Sure, that's cool | 00:19 |
| cr1901_modern | May I take a bit of time to ask about project layout? | 00:19 |
| cr1901_modern | mithro: ^^ | 00:19 |
| mithro | cr1901_modern: see the existing repo | 00:33 |

| xfxf | mithro: you around? | 08:54 |
| mithro | xfxf: kinda | 08:55 |
| xfxf | mithro: i notice the boards have headers for LED's and reset, should i hook any of the case things to it? | 08:55 |
| xfxf | like, is there a power button / LED? | 08:55 |
| mithro | xfxf: yes - but the firmware doesn't support them yet :P | 08:55 |
| xfxf | ah, np | 08:55 |
| xfxf | cases arrived today | 08:55 |
| xfxf | i'm assembling two for testing and will leave the rest for the hackfest | 08:55 |
| xfxf | yuou're right, those cases i bought are horrible | 08:55 |
| xfxf | can i recommend we put these new cases up on the hdmi2usb site somewhere as recommended? | 08:56 |
| mithro | you mean like https://opsis.hdmi2usb.tv/getting-started/case.html ? | 08:56 |
| mithro | xfxf: Also signed up for Amazon referral program, so we get money if people buy through that link | 08:57 |
| xfxf | ah neat, didn't see that | 08:57 |
| mithro | xfxf: It's about 7 days old I think :) | 09:00 |
| xfxf | the power is a bit annoying | 09:03 |
| xfxf | i saw a bunch of very short barrel extension cables, getting a few of those might be nice | 09:04 |
| mithro | xfxf: How big are your power bricks? | 09:20 |
| xfxf | i have a mix of power bricks and wall warts | 09:20 |
| xfxf | power bricks are 3A | 09:20 |
| xfxf | i've plugged ine of the power bricks | 09:20 |
| xfxf | i don't like how the cable now hangs out of the case with the brick on it | 09:20 |
| xfxf | i can see the connector on the board getting damaged | 09:21 |
| xfxf | CarlFK: when do you leave the US? | 09:21 |
| xfxf | http://littlebirdelectronics.com.au/products/barrel-jack-extension-cable-m-f-3-ft | 09:23 |
| xfxf | mithro: thinking about getting 10x of those | 09:23 |
| mithro | xfxf: I had a plan of mounting the brick inside the case where the fan is | 09:23 |
| mithro | xfxf: but I'm guessing your bricks are too big? | 09:23 |
| xfxf | they are yes | 09:24 |
| xfxf | i don't think you'd get a brick that would fit, it's a fairly small area | 09:24 |
| mithro | xfxf: we have ones at work that do | 09:24 |
| xfxf | ok, i'd need models, because i had very little to go by when ordering | 09:24 |
| xfxf | you literally said >1a 12v :P | 09:24 |
| mithro | xfxf: they aren't the right voltage | 09:25 |
| xfxf | ah, right | 09:25 |
| xfxf | thoughts on ordering those extension cables? | 09:25 |
| mithro | xfxf: It would be good if we could get some "plugs" which fit in the holes somehow with them | 09:26 |
| xfxf | i'm not sure we've got the time to be too picky now | 09:26 |
| xfxf | given we need these in a week | 09:26 |
| mithro | xfxf: are they long enough? | 09:26 |
| xfxf | well, with an extension cable, i think so | 09:26 |
| xfxf | it's a hell of a lot better than the ~1m they are now | 09:27 |
| mithro | xfxf: pics? | 09:27 |
| mithro | xfxf: I think you are probably right | 09:27 |
| xfxf | not sure there's much to take a picture of | 09:27 |
| xfxf | power pack with ~1m cable | 09:27 |
| *** rohitksingh has joined #timvideos | 09:36 | |
| mithro | xfxf: I mean of how you are putting things in the case | 09:42 |
| mithro | xfxf: what standoff size are you using? | 09:42 |
| xfxf | i put the board in the case and screwed it in using the supplied screws | 09:42 |
| mithro | xfxf: hrm? | 09:43 |
| xfxf | i'm confuused as to your question | 09:43 |
| mithro | you need standoffs between the board and the holes in the case | 09:43 |
| xfxf | okay, that's not going to be obvious to others | 09:44 |
| xfxf | i have one working fine without them | 09:44 |
| xfxf | i hope i haven't fried anything | 09:44 |
| xfxf | mithro, there's nothing about standoffs on the case page | 09:48 |
| xfxf | i'm utterly confused, what do you mean by 'standoffs' | 09:48 |
| xfxf | and where am i supposed to get them? | 09:48 |
| mithro | xfxf: http://apexfasteners.com/fasteners/images/categories/MaleFemaleStandoff.png | 09:48 |
| xfxf | i mounted it into the case like i'd mount any motherboard | 09:48 |
| xfxf | the case already has raised bits | 09:49 |
| xfxf | the case also doesn't come with any of those | 09:49 |
| xfxf | https://usercontent.irccloud-cdn.com/file/H1rTNFxF/irccloudcapture1752555174.jpg | 09:54 |
| xfxf | i'm lost why you'd want to add standoffs on top of those when those are good enough for normal matx motherboards | 09:55 |
| mithro | xfxf: I'm pretty sure a motherboard isn't designed to be directly mounted on those? | 09:59 |
| xfxf | fairly confident it is, it's how most cases are these days | 10:00 |
| xfxf | well, the tiny ones anyway | 10:00 |
| xfxf | the case doesn't come with any standoffs | 10:01 |
| xfxf | there are plastic standoffs with the hdmi2usb, but they're way longer then the screws provided, so won't work | 10:04 |
| xfxf | and they're female on both ends so also won't work | 10:04 |
| xfxf | i still think we need to 3d print cases for these things so all ports are exposed | 10:10 |
| mithro | xfxf: I ordered a bunch of standoffs to be delivered to your place (and a second copy to be delivered here) | 10:13 |
| xfxf | i'm not convinced they're needed for this case - nothing on the board is touching the case | 10:13 |
| xfxf | and they come with a clear plastic sheet with MATX holes already cut in it - i've just mounted the hdmi2usb on top of it as insulation | 10:14 |
| xfxf | given the plastic sheet is there, and there's no standoffs, i'm fairly confident these are designed to be used without standoffs | 10:14 |
| xfxf | especially given the height of the board is aligned to the back open panel to where i'd expect it to be | 10:15 |
| xfxf | i.e. ~3mm up | 10:15 |

| mithro | xfxf: https://opsis.hdmi2usb.tv/getting-started/layout.html | 12:52 |
| xfxf | cool! | 12:58 |
| xfxf | what are the plans for the SD card btw? | 12:58 |
| xfxf | and is it micro SDXC compatible? | 12:58 |
| xfxf | i'm also assuming both TOFE boards i got currently don't do anything? | 12:58 |
| xfxf | because as a prior VJ i'm pretty damned keen to play with the milkymist stuff at some point | 12:58 |
| xfxf | but assume no firmware support yet | 12:59 |
| mithro | xfxf: it should work at pretty large capacities / high speeds but it doesn't have the extra pins of the newest standards | 12:59 |
| mithro | xfxf: just software :) | 12:59 |
| xfxf | so who is making the milkymist stuff work? _florent_ ? | 13:00 |
| xfxf | obviously not critical for LCA, just personally curious | 13:00 |
| mithro | Nobody at the moment | 13:16 |
| mithro | Insert developers here :-P | 13:17 |
| mithro | I didn't get a chance to look at the 30fps problem | 13:18 |
| xfxf | that's fine, i've been building hardware and trying to organise venue/bump in logistic stuff tonight | 13:21 |
| xfxf | mithro: okay, possible issue that needs to be fixed - my pro cameras, being australian, won't do 720p60. 720p50 only. they don't work with hdmi2usb with the 720p60 mode at all, no picture ever comes in | 14:07 |
| xfxf | and on 720p50 mode, it's not working properly either - i get a few frames and then it stops | 14:07 |
| xfxf | input0: shows 1280x0 | 14:07 |
| xfxf | then 0x0 | 14:07 |
| xfxf | is it possible to get your firmware to capture at 25fps - australia is 720p50, not 60, i can see problems having to put everything at 60 in terms of captured video looking a bit juddery | 14:08 |
| xfxf | + i'm still dubious the uni doesn't have scan converters for their gear in each room which is locked to 50 | 14:09 |
| micolous | Plus the lights will flicker | 14:10 |
| xfxf | yes, that too | 14:13 |
| xfxf | actually i'm pretty much going to say we need 25fps/50hz capture as a requirement | 14:13 |

| xfxf | re me asking about when you were leaving I was going to see if I could get some power cables express shipped to you | 23:19 |
| xfxf | but I found a local vendor that wasn't too much more expensive so went that route | 23:19 |
