This group defines all used Inter-Integrated Circuit (I2C) interfaces.

Each I2C interface is a sub group with the I2C name as the group name.

Serial Clock.

type: String

serial data signal.

type: String

name of the I2C peripheral to use.

type: String

Describes the role in the communication. Possible values are:

• master
• slave

type: enum

7bit Address or 10 bit Address

fastest speed (shotest bit time) to use on the SCL line.

• Standard Speed (up to 100 kHz)
• fast mode (up to 400 kHz)
• fast mode plus (up to 1000 kHz = 1 MHz)
• high speed mode (up to 3.4 MHz)
• ultra fast mode (up to 5 MHz)
