At a quick glance, I don’t see why One-Wire stuff wouldn’t work. It would be nice to know what I2C address those sensors use. Currently, with the OS board and the LCD my I2C address table looks like this:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: 20 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- 48 -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- -- -- -- -- 68 -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
The above is found my running `i2cdetect -y 1` for the Rev2 Pi. Those addresses translate to 0x20, 0x48 and 0x68. The 0x20 is the LCD and the 0x48 and 0x68 are the OSPi. Don’t quote me.
