The sets of addresses do not intersect: the 7 bit address 0x10 is not the same as the 10 bit address 0x10 (though a single device could respond to both of them). You select a 10 bit address by adding an extra byte after the address byte: - S Addr7 Rd/Wr .... + S Addr7 Rd/Wr .... becomes S 11110 Addr10 Rd/Wr S is the start bit, Rd/Wr the read/write bit, and if you count the number of bits, you will see the there are 8 after the S bit for 7 bit addresses, and 16 after the S bit for 10 bit addresses. -WARNING!

There are several places in the code that will cause SEVERE PROBLEMS with 10 bit addresses, even though there is some basic handling and hooks. Also, almost no supported adapter handles the 10 bit addresses correctly. -- 1.7.1.251.gf80a2 -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
