To finish off completely hijacking your thread :) does anyone know of
anything that can run a master/slave interface like pcf(4) which appears
to have been an ISA bus only device? I don't have C skills to write
one, though 400kHz master and slave routines in AVR asm were fun :)
Later: after nearly losing this in a pine crash (don't ask), I've since
seen John's reply to your later message. Could it be that smbus or
something is also using iicbus rather than something messing with ppbus?
Thanks for the hints. I don't have smbus in the kernel, nor do I have
any other i2c device drivers loaded in the system.
I stopped using smbus when it became pretty clear that it wasn't doing
anything useful for me (it could never see CPU fan readouts or anything
like that when I tried it on 3 different PIII era systems).
I agree a pcf(4) style interface would go some way towards solving the
problem, however, solder plus 74LS05 costs next to nothing, plus the
"leet value" of having a circuit schematic in the man page had to be
tried out. I think we're losing out there if it's not working, though.
PS OpenBSD look like they took NetBSD's i2c and ran with it...
cheers
