<mjmdavis[m]> is there an existing appelet that will let me just read a clocked spi like signal?
<whitequark[cis]> i don't think so
<mjmdavis[m]> I guess I could write SPI to an unconnected pin?
<mjmdavis[m]> no, it doesn't stay open
<whitequark[cis]> wait, who drives the clock here?
<mjmdavis[m]> good point
<mjmdavis[m]> didn't think of that
<mjmdavis[m]> spi-controller

<alephbias[m]> reading through the code, it looks like there's no support for cJTAG in the Glasgow. There's an allusion to it here: https://github.com/GlasgowEmbedded/glasgow/blob/560d8dcbfb15282cd530ab6ffffed87824abc4dd/software/glasgow/applet/interface/jtag_probe/__init__.py#L7
<alephbias[m]> Is anyone aware of work to support cJTAG? Or is this a "Patches welcome" situation? 🙂
<whitequark[cis]> there is no work on cJTAG that i'm aware of; i have a board with cJTAG but the spec is uhhh nightmarish

<alephbias[m]> That's the conclusion I'm coming to as well :Melting:
<whitequark[cis]> I kind of want to implement it one day but I'm kind of busy with other things right now
<whitequark[cis]> I expect I'll have more time for Glasgow later this year and ideally I will spend a year or two working full time on it
<alephbias[m]> I've now run into two manufacturers that use it, and I suspect if I run into a third I'll try my hand at something. But the spec sure is pricey
<whitequark[cis]> I should have it somewhere...
<whitequark[cis]> or a spec-equivalent document

<darius0949[m]> you know, I was expecting an Australia tax for shipping here but not quite this much
<darius0949[m]> the Euro store has slightly less "fuck you" shipping cost at least 😭
<whitequark[cis]> wow
<whitequark[cis]> that's uh , painful
