| futarisIRCcloud | _florent_ : Should vga_out psave_n be tied high or low? I made the changes to hdmi2usb/firmware to add vga_out0, but can't seem to get any output. I haven't hooked up an oscilloscope or logic analyser though. | 02:51 |

| agronaught | hello... lca attendee here, anybody on? | 06:10 |
| futarisIRCcloud | Yep | 06:10 |
| agronaught | cool. I'm just playing with the litex-build bits and trying to find my way around, thought I should join IRC for the first time in > 20 years. | 06:11 |
| futarisIRCcloud | tumbleweed: the hdmi2usb pattern generator was fine by you right. It's yuv only right? Not RGB... | 06:13 |
| futarisIRCcloud | Most people use IRCcloud or riot / matrix to connect to IRC these days. Although, you could use any old IRC client if you prefer. | 06:16 |

| mithro | How do I edit that? | 21:09 |
| CarlFK[m] | I think it just lets you edit? | 21:19 |
| CarlFK[m] | looks like you figured it out | 21:19 |
| mithro | CarlFK[m]: can you see those edits? | 21:20 |
| CarlFK[m] | yes | 21:20 |
| CarlFK[m] | mithro (IRC): where is the details you need tested or something for the hdmi test pattern on Arty thing you said needed testing ? | 21:22 |
| mithro | It needs to be built first | 21:22 |
| mithro | And I don't have any instructions or time to write up a how to guide | 21:23 |

| CarlFK[m] | is that something that is ready to be be sent off to Oshpark and then solder a bunch of stuff to it? | 21:27 |
| futarisIRCcloud | CarlFK[m]: There are also these PMOD to DVI/HDMI boards: https://blackmesalabs.wordpress.com/2017/12/15/bml-hdmi-video-for-fpgas-over-pmod/ | 21:44 |

| mithro | futarisIRCcloud: That isn't very interesting due to the cost of the parts on that board | 21:45 |
| futarisIRCcloud | mithro: Yeah, the PTN3363 is a whole lot cheaper than the TFP410. | 21:49 |
| mithro | It's just a level shifter verses actual silicon which does stuff | 21:49 |
| futarisIRCcloud | I can order and solder up some PTN3363 boards, if you're sure the design will work. | 21:49 |
| mithro | futarisIRCcloud: It's copied from the apertus HDMI design -- so it is pretty likely to work | 21:50 |
| mithro | but nobody has actually tested it yet | 21:50 |
| futarisIRCcloud | mithro: 5mil/5mil, so OSH park should be fine? | 21:52 |
| mithro | futarisIRCcloud: I think you need to use the 4 layer process (but have two layers blank) | 21:52 |
| mithro | futarisIRCcloud: I also have a bunch of the PCBs with me -- I should have given them out at LCA.... | 21:53 |
| mithro | futarisIRCcloud: I can drop some in the mail tomorrow | 21:56 |
| mithro | CarlFK[m]: I can drop some in the mail to you too if it makes sense... | 21:56 |
