While waiting on Raspberry Pi I was looking for connecting 1-wire bus to it. Probably the easiest(apart from GPIO) way is to use I2C devices. The only problem is that Raspi uses 3.3V I2C but Stuart Poulton published designs with few transistors that handle the different levels http://raspberrypi.homelabs.org.uk/raspberrypi-1-wire-expansion/
But there is a new chip from Maxim/Dallas that does this conversion so you can have %v on 1wire and 1.8V or 3.3V on I2C. It comes in two packages SOT/6(this one's easy to solder) TDFN-EP/8. I've seen it maybe a month ago but I couldn't get it anywhere. Now samples are available. It has strong pull up so it's suitable for parasite powered networks. http://www.maxim-ic.com/datasheet/index.mvp/id/7630 And I think a question for Paul is it supported yet? Maybe it's not so different from older I2C converter DS2482? Do You plan to support it in the future? -- p4trykx ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
