<whitequark> SINGLE WIRE CAN
<whitequark> WHY
<sorear> what if: truly single wire using rf space changes
<whitequark> wtf, this is really confusing
<whitequark> the nmigen branch hangs before an applet finishes running
<whitequark> but... in python code
<whitequark> regardless of gateware even
<_whitenotifier-3> [GlasgowEmbedded/Glasgow] whitequark pushed 1 commit to master [+0/-0/±1] https://git.io/fjQNA
<_whitenotifier-3> [GlasgowEmbedded/Glasgow] whitequark 984e8cb - applet.internal.benchmark: fix unnecessarily r/w register to be r/o.
<_whitenotifier-3> [GlasgowEmbedded/Glasgow] whitequark pushed 10 commits to nmigen [+1/-1/±64] https://git.io/fjQNx
<_whitenotifier-3> [GlasgowEmbedded/Glasgow] whitequark 54f0e10 - Bulk port of all gateware to nMigen compatibility layer.
<_whitenotifier-3> [GlasgowEmbedded/Glasgow] whitequark b022bc0 - gateware.analyzer: adjust for nMigen.
<_whitenotifier-3> [GlasgowEmbedded/Glasgow] whitequark 5ba4f74 - gateware.pads: adjust for nMigen.
<_whitenotifier-3> [GlasgowEmbedded/Glasgow] ... and 7 more commits.
<whitequark> `glasgow run benchmark` succeeds on nmigen!!!
<tnt> whitequark: what was cuasing the hangup ?
<whitequark> no idea
<whitequark> still hangs
<tnt> oh, ok, I thought when you said benchmark was running that you had found the issue.
<whitequark> it hangs after the benchmark is done
<whitequark> but before the latest nmigen fixes, it didn't actually succeed
<whitequark> there was a problem with ResetInserter in compat mode

<kc8apf> whitequark: apparently Tesla use that single wire CAN for data transfer between car and charger
<ebb> Makes sense for short runs
<ebb> Short, relatively point-to-point runs
<TD-Linux> looks like the "single wire CAN" is just normal CAN but not differential. already "supported" by any CAN applet for glasgow
<TD-Linux> (nevermind that LIN already exists for this)
<whitequark> ahhh
<whitequark> but... why would you voluntarily make something not differential
<whitequark> this looks like pure penny pinching?
<whitequark> unless they're pin limited
<tnt> maybe you can put it over fiber ?
<TD-Linux> one wire versus 2. cars are extreme penny pinching
<gruetzkopf> pin limited, at least for charging connectors
<gruetzkopf> the european one is PE+N+3P, plus detect plus comm (usually square wave bullshit), plus maybe 2x high current DC
<kc8apf> Tesla uses it on the pilot signal on the connector
<zkms> there's also the BEAN bus on Toyotas, iirc it's also a single wire bus

<TD-Linux> kc8apf, I think that's 2 wire CAN though. same for chademo
<kc8apf> nope, it's that chip. Came from a Tesla wall charger teardown
<TD-Linux> oh lol nice
<TD-Linux> gruetzkopf, the square wave thing for L2 chargers is actually the best thing ever. analog, reliable, DRM impossible
<TD-Linux> cute how it has provisions for lead acid batteries
