mithroCarlFK[m]: Merged00:00
mithrofutarisIRCcloud: That looks like maybe you don't have a strong enough drive strength?00:01
mithrofutarisIRCcloud: What does the Vivado example set in the ucf file (or what ever replaced UCF in Vivado...)00:02

mithrofutarisIRCcloud: Well, don't see anything super special there00:13
futarisIRCcloudmithro: Me either.  I suspect pix or cd_pix isn't clocking...00:17

futarisIRCcloudmithro: Is there a PDF schematic for pmod-hdmi?  Or do I need to run KiCad?00:26
mithrofutarisIRCcloud: Run kicad probably00:26
futarisIRCcloudmithro: Cheers. Seems straightforward enough to write a targets/arty/video-pmod-hdmi-tx.py ... Nice that we can run HDMI off a single PMOD.  Did you have PCBs for RX too?01:12
mithrofutarisIRCcloud: I have a design but not actually tested -- it's a bit hard because of issues around the clock input routing01:12
futarisIRCcloudmithro: Ok. Do you have a part list / BOM for pmod-hdmi-tx?01:15
mithrofutarisIRCcloud: only in the kicad01:25

futarisIRCcloudI suspect, https://github.com/timvideos/HDMI2USB-fx2-firmware/issues will work on them.04:00
tpbTitle: Issues · timvideos/HDMI2USB-fx2-firmware · GitHub (at github.com)04:00
mithrofutarisIRCcloud: You want the sigrok firmware -> https://sigrok.org/wiki/Fx2lafw04:01
tpbTitle: fx2lafw - sigrok (at sigrok.org)04:01
mithrofutarisIRCcloud: But yes, you can use them for testing some of the fx2 firmware if you want04:01
futarisIRCcloudmithro: Yep.  Theoretically, a pattern generated from an arty would work with that, if there's enough bandwidth over 8 bits GPIO, right?04:06
mithrofutarisIRCcloud: Hrm?04:06
futarisIRCcloudmithro: Never mind. I just had a look at https://reference.digilentinc.com/_media/reference/programmable-logic/atlys/atlys_sch.pdf pg 5 ... There aren't enough pins for the FIFO, without soldering directly to the board...04:12

mithroCarlFK[m]: LGTM! Merged16:23
CarlFK[m]mithro: either one.  and yay.  now to figure out how to find the most resent existing build16:25
mithroCarlFK[m]: Can you look at running pep8 or something over that code too?16:30
CarlFK[m]mithro (IRC): um.. any quick tips on how to do that?16:31
CarlFK[m]sudo apt install pep8 ...16:31
mithroautopep8 should work I guess?16:31
mithroOr what was the other one -- yapf or something16:31
