The I2C is a simple communication standard intended to move small amounts of data a few inches between chips. Please See I2C Wikipedia page for additional information.
I2C addresses
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.
Neo1973
On the Neo1973, we currently use the following addresses on the I2C bus:
Device | I2C address |
PCF50606 | 0001 000x |
WM8753L | 0011 010x |
LM4857 | 1111 100x |
