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
Personal tools
