In AmigaOS one can use the i2c.resource component [25] for AmigaOS 4.x and MorphOS 3.x or the shared library i2c.library by Wilhelm Noeker for older systems. Arduino developers can use the "Wire" library. CircuitPython and MicroPython developers can use the busio.I2C or machine.I2C classes respectively.
English: Sample Inter-Integrated Circuit (I²C) schematic with one master (a microcontroller) and three slave nodes (an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), and a microcontroller)
The Power Management Bus (PMBus) is a variant of the System Management Bus (SMBus) which is targeted at digital management of power supplies.Like SMBus, it is a relatively slow speed two wire communications protocol based on I²C.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]

The System Management Bus (SMBus or SMB) is a single-ended simple two-wire bus for the purpose of lightweight communication. Most commonly it is found in chipsets of computer motherboards for communication with the power source for ON/OFF instructions.
To begin communication, the SPI main first selects a sub device by pulling its CS low. (Note: the bar above CS indicates it is an active low signal, so a low voltage means "selected", while a high voltage means "not selected")
