mithrocr1901_modern: Ping?05:36
cr1901_modernmithro: This weekend is kinda shot, sorry. I'll try working on something later this morning06:08
mithrocr1901_modern: At some point I would like you to try and replicate my sigrok stuff06:09
cr1901_modernmithro: Okay, what I _was_ gonna write was "I'll be gone from about 2:00 PM EDT today till possibly 9:00 PM EDT", but...06:09
cr1901_modernthat sounds like something perhaps low cognitive bandwidth I could do when I get back :)06:10
mithrocr1901_modern: No huge hurry06:10
cr1901_modern(famous last words)06:10
mithrocr1901_modern: Also like comments / thoughts on

Ishan_Bansalmithro : ping07:20
Ishan_BansalI have made the changes on the pull request for huffman module, kindly review whenever you are free.07:21
tpbTitle: Adding Huffman to JPEG encoder by ishan98 · Pull Request #3 · timvideos/litejpeg · GitHub (at
Ishan_Bansalmithro : Also two of your comments I'm not able to understand so can you elaborate on that.07:22
mithroIshan_Bansal: I'll try and get to it shortly07:23
Ishan_Bansalmithro : Np, going for lunch back in about 30 minutes.07:24
paddatrappermithro: pong?11:19
mithropaddatrapper: Pong :-)11:19
tpbTitle: GitHub - mithro/libsigrok at litescope (at
mithropaddatrapper: I think we can use this to capture the FX2 on the Opsis signals11:21
paddatrappermithro: ah awesome! That would be incredibly useful11:21
mithropaddatrapper: Will you have a couple of hours to see if we can get it going for you?11:22
paddatrappermithro: sure. Will be able to a bit later today11:23
mithroOkay, I'll be around for ~5ish hours11:24
paddatrappermithro: OK, ready to test14:41
mithropaddatrapper: It's 12:43 here, so I'm actually thinking about bed...14:44
paddatrappermithro: no worries, I'll give it a try (I assume just build and run?) and post any issues I run into14:46
mithropaddatrapper: Ha! No :-P14:46
paddatrappermithro: I guess I should stop living in the hope that eventually one day a project will be that easy to work on!14:48
mithropaddatrapper: You'll want to build sigrok from source and then replace libsigrok with mine version at
tpbTitle: GitHub - mithro/libsigrok at litescope (at
paddatrappermithro: ok cool14:49
mithropaddatrapper: Then you'll need to build some gateware for the Opsis which has litescope in it14:50
mithropaddatrapper: I was working on some of that here ->
tpbTitle: GitHub - mithro/HDMI2USB-litex-firmware at litescope (at
mithropaddatrapper: You'll want to set it up so you can talk to the FPGA via the Ethernet14:50
paddatrappermithro: ok need to scavenge a power supply for a switch somewhere then14:52
* paddatrapper has 3 switches sitting on my desk, without a single power supply between them...14:52
mithropaddatrapper: You probably don't want a switch between you and the Opsis14:53
paddatrappermithro: ok14:53
mithroI'd recommend picking up something like this ->
tpbTitle: USB 3.1 Type-C 3-Port Hub + Gigabit Ethernet Network Adapter (at
tpbTitle: Belkin USB 3.0 3-Port Hub with Gigabit Ethernet Adapter - Apple (at
CarlFK[m]paddatrapper: if you are worried about crossover, gig-e does that automatically.14:54
mithropaddatrapper: They should be like $10-$15 USD on Amazon or Ebay14:54
paddatrapperCarlFK[m]: it's more I still would like to be connected to the internet, and the tower I'm working on doesn't have a second NIC14:55
paddatrappermithro: I've got a gig-e NIC lying around somewhere, I just need to find it14:56
CarlFK[m]ah - yeah, 2nd nic is the way to go.  card or usb, both are fine14:57
paddatrappermithro: though that would be useful for my laptop, which only has 10/10014:59
mithropaddatrapper: Yeah14:59
mithropaddatrapper: That above picture is from this gateware design ->
tpbTitle: HDMI2USB-litex-firmware/ at litescope · mithro/HDMI2USB-litex-firmware · GitHub (at
mithropaddatrapper: But of course you can't use the FX2 as a serial port for litescope if you debug it -- so you need to use either the ethernet or lsio uart15:01
paddatrappermithro: yeah, makes sense15:02
mithroI was working on making this SoC work ->
tpbTitle: HDMI2USB-litex-firmware/ at litescope · mithro/HDMI2USB-litex-firmware · GitHub (at
mithroBut got distracted15:02
mithroWell, I heave to head to bed, since it's 1:30am here15:22
mithropaddatrapper: You should also test the scripts in the ./test/ directory15:22
paddatrappermithro: ok will do15:22
mithropaddatrapper: I would try and get to run as the first step15:26
tpbTitle: HDMI2USB-litex-firmware/ at litescope · mithro/HDMI2USB-litex-firmware · GitHub (at
mithropaddatrapper: Oh, you'll need your machine to be configured as and the FPGA will appear as
paddatrappermithro: ok, busy building sigrok at the moment15:27
