Tsk, tsk. ;) There is a beautiful schematic on the CD. You can't blame AD, their kit is excellent. Had I read it before posting, I wouldn't have to ask Sean about it (although my knowledge isn't sufficent to refuse confirmations). > I think that i2c-pcf-epp is for a Phillips I2C controller chip wired > to a parallel port.

You're right, i2c-pport is obviously what I need. I tweaked the values there to match what I read on the schematic. I think I have everything OK, but I can't get it to work for some reason. See my reply to Sean for details. -- Jean Delvare http://www.ensicaen.ismra.fr/~delvare/
