I have drawn up a modest size schematic in KiCAD, for the first time.
It seemed more or less straight forward. But now that I run the ERC error checker, I get boatloads of errors with seemingly disconnected pins even though the automatic junctions appears. The most frequent error being:
"Pin connected to other pin but not driven"
It's random where it comes and where it doesn't even in setups that were copy pasted. Sometimes I need to unplug things and put them back together one by one, sometimes it's the little power components and sometimes the passive ones and sometimes I just move out the entire chip and put it back in. It sometimes fixes those problems and sometimes I rip my hair out doing it over and over and it just won't go away. Here is one on pin 1 of U24, no matter what I do it comes back. Similar problems on pins 2, 3, and 4 although they don't appear in the error box near this one.
This is very annoying and it must be bugs in KiCAD that is showing components connected, even with junctions, but the underlying model is apparently randomly different from what's shown.
Or can I just ignore those errors? And is there a way to tell the checker to ignore particular errors — I know one can suppress classes of errors and warnings, but I mean particular occurrences of them. For example the second error (warning) "Conflict problem between pins …" tri-state signal pin connected to fixed GND or +5V, the warning is fine once, but once I checked and find it correct, I want to acknowledge the particular warning and make it not be raised again, I don't want to see it any more. Same thing with disconnected pins, disconnected outputs shouldn't be a problem, I want to tell the checker that it is fine in particular cases.
