Dear List,
this is my first post here and I am not sure if this is a suitable topic
here. Anyway I have a Velleman K8000 IO-card and it uses I2C over
parallel port to communicate.
when I modprobe i2c-parport it does not complain. I tested without card
connected and it complained so it seems to find the card.
modprobe pcf8591
modprobe i2c-core
modprobe i2c-dev
I am not sure I am doing it right. Should i2c-core probed first ?
anyway now I have
/dev/i2c-0 /dev/i2c-1
Now I don't know whether these i2c-devices refer to this Velleman board
or some other i2c-device which happen to be in the computer...
If these devices probably refer to Velleman - then how I can refer
different i2c-devices on the board.
I am totally new to this i2c thing (reading spec at the moment but it
does not help much with Linux).
I would be very greatfull if some could point me the way - thanks.
Best Regards
Kari Laine
