mithrofutarisIRCcloud: That looks like maybe you don't have a strong enough drive strength?00:01

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/ ... 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: 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 pg 5 ... There aren't enough pins for the FIFO, without soldering directly to the board...04:12
