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

| futarisIRCcloud | mithro: Me either. I suspect pix or cd_pix isn't clocking... | 00:17 |

| futarisIRCcloud | mithro: Is there a PDF schematic for pmod-hdmi? Or do I need to run KiCad? | 00:26 |
| mithro | futarisIRCcloud: Run kicad probably | 00:26 |
| futarisIRCcloud | mithro: 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 |
| mithro | futarisIRCcloud: I have a design but not actually tested -- it's a bit hard because of issues around the clock input routing | 01:12 |
| futarisIRCcloud | mithro: Ok. Do you have a part list / BOM for pmod-hdmi-tx? | 01:15 |
| mithro | futarisIRCcloud: only in the kicad | 01:25 |

| tpb | Title: fx2lafw - sigrok (at sigrok.org) | 04:01 |
| mithro | futarisIRCcloud: But yes, you can use them for testing some of the fx2 firmware if you want | 04:01 |
| futarisIRCcloud | mithro: Yep. Theoretically, a pattern generated from an arty would work with that, if there's enough bandwidth over 8 bits GPIO, right? | 04:06 |
| mithro | futarisIRCcloud: Hrm? | 04:06 |
| futarisIRCcloud | mithro: 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 |

| CarlFK[m] | mithro: either one. and yay. now to figure out how to find the most resent existing build | 16:25 |
| mithro | CarlFK[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 |
| mithro | autopep8 should work I guess? | 16:31 |
| mithro | Or what was the other one -- yapf or something | 16:31 |
