I2C is a simple communication standard intended to move small amounts of data a few inches between chips. See wikipedia.
We currently use the following addresses on the I2C bus:
| Device | I2C address |
| PCF50606 | 0001 000x |
| WM8753L | 0011 010x |
| LM4857 | 1111 100x |
Note that I2C addresses are 7 bit. The last bit, which is not part of the address, indicates whether this is a read or write operation. So "0001 000x" is 0x8, not 0x10.
