After spending quite a bit of time with my 1 wire components. I would like to know if I can use owfs directly on one of the gpio inputs of the raspberry, without going through another component in the interface. With the DS2423 and DS18B20, it's doable, but I have not found a solution for the DS2450.
On Arduino, I managed to do it, but on my 4 A / D channels, I only have a precision of 0.1 volts, which is insufficient for my pressure and humidity sensor. I probably need to go through a modofication of the DS2450 library, but I am not very comfortable at this level.
