rohitksingh_workfutarisIRCcloud: Indeed! Circuit design as well as simulation using single library is super-cool!! After all the experiment with Spice, just import the netlist into KiCad, route it and good to go!03:57

futarisIRCcloudHi all. Looking to hack on PMOD-VGA again this weekend. Anyone have any further suggestions on where to start?  I've got an oscilloscope and logic analyser now. Best to remove things from the config, and work up? Hard code clocks? Or just get pix_clk for vga outputting on a pin?07:42
futarisIRCcloudI haven't really tried setting up just a bridge, and the vga peripheral either, as I don't quite follow how to do that.07:42
futarisIRCcloud_florent_ & mithro: Any notes or documentation on how set up a bridge and single peripheral?07:43

futarisIRCcloudmithro: Or am I better off running FuPY and connecting to it using iPython, and writing to the registers manually?08:14

_florent_futarisIRCcloud: it's probably better to just debug where you are. First thing is to have the right pix_clk. You can probe it with your scope or output it on one led with a counter dividing it14:20

mithroDid you see my stuff from last night?22:28
CarlFKmithro: kinda.  I clicked around but didn't try running anything yet22:28
mithroI didn't update the download-prebuilt script - I was leaving that to you22:31
mithroCarlFK: but in theory it should be like 2 or 3 http requests now22:32

CarlFKmithro: add those do the top of the dl script - I don't expect to work on it for at least a few days23:06
CarlFKpointers to the code that creates them would be good too - i some how expect to wonder "how did this happen?"23:07

futarisIRCcloudmithro: Thanks for the link. Any examples of a bridge without a CPU?23:43
mithrofutarisIRCcloud: That is a bridge without a CPU23:43
futarisIRCcloudAhh. Whoops. Didn't see kwargs['cpu_type'] = None ...23:44
futarisIRCcloudmithro: So I can just connect sigrok to that? I saw in the litescope repo some references to vcd and sigrok...23:48
futarisIRCcloudAnd some csv and py...23:49
mithrofutarisIRCcloud: litescope is different from the bridge23:55
futarisIRCcloudmithro: Ok.23:59
mithrolitescope is the "analyzer" thing in that example23:59
