Re: [Owfs-developers] OWFS 3.2P4 will build on Raspberry Pi

Hello!
Thank you confirming that. I do not plan on using the kernel driver for the functions.

Be aware the DS28E17 is a 3.3V only device. It's not 5V tolerant. At
first it appears to be but you will fry it instantly if a 5V onewire is
connected while the power is disconnected.

The DS28E17 is only supported by the kernel driver. So you need to use
it with one of the Onewire host adapters that is supported by the
kernel. OWFS isn't involved but may be run in parallel with the --w1
option, or independently on other host adapters.

Do not use both the ds2482 kernel driver and the --i2c option of OWFS on
the same I²C Onewire hostadapter. This meant concurrent access on the
DS2484 chip and leads to all kind of tricky malfunctions.

Kind regards
